    BACKGROUND



    [0002] In researches on a 5th-Generation (5G) mobile communication technology, a Beamforming (BF) technology is an important technology for improving coverage and spectrum efficiency.

    DETAILED DESCRIPTION



    [0006] The technical solutions in the embodiments of the disclosure will be clearly and completely described below in combination with the drawings in the embodiments of the disclosure.

There are no limits made in the embodiments of the disclosure.

    [0010] In the embodiments of the disclosure, a network device may be a device configured to communicate with the terminal device. The network device may be a Base Transceiver Station (BTS) in the GSM or the CDMA, may also be a NodeB (NB) in the WCDMA system, may also be an Evolutional Node B (eNB or eNodeB) in the LTE system and may further be a wireless controller in a Cloud Radio Access Network (CRAN) scenario. Alternatively, the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network device in the future 5G network, a network device in the future evolved PLMN or the like. There are no limits made in the embodiments of the disclosure.

    [0011] FIG. 1 is a schematic diagram of an application scenario not being part of the invention. A communication system in FIG. 1 may include a terminal device 10 and a network device 20. The network device 20 is configured to provide communication service for the terminal device 10 and access to a core network. The terminal device 10 searches a synchronization signal, broadcast signal and the like sent by the network device 20 to access the network, thereby communicating with the network. Arrows illustrated in FIG. 1 may represent uplink/downlink transmission implemented through a cellular link between the terminal device 10 and the network device 20.

    [0012] In researches on 5G, a Beamforming (BF) technology is an important technology for improving coverage and spectrum efficiency. BF is an implementation manner for an intelligent adaptive array antenna as well as a digital signal processing technology implemented on an antenna array consisting of multiple array elements. With the BF technology, differences of a desired signal and an interference signal in spatial channel characteristics such as an angle of arrival are utilized, a proper weighted value is set for the antenna array and the desired signal and the interference signal are spatially isolated, so as to reduce interference between users and improve a system capacity.

    [0013] In order to conveniently understand the embodiments of the disclosure, the BF technology will be simply introduced below with dual-stream BF in FIG. 2 not being part of the invention. As illustrated in FIG. 2, two data streams of a sender are scrambled and modulated respectively, then are subjected to antenna layer mapping and precoding processing and enter a BF unit. Two groups of beamforming coefficients are calculated for the two different data streams to beamform the two data streams respectively, and the beamformed data streams are sent to antenna ports and pointed to different users.

    [0014] During uplink transmission, a terminal device may adopt different beams to send multiple signals and a network device indicates the beam with optimal receiving quality in the beams as a beam for subsequent uplink signal transmission. Meanwhile, the terminal device may also adopt the same beam to send multiple same signals, and the network device adopts different beams to receive the multiple signals, thereby selecting the beam with optimal receiving quality as a beam for subsequent signal receiving.

    [0015] Similarly, during downlink transmission, the network device may adopt different beams to send multiple signals and the terminal device indicates the beam with the optimal receiving quality in the beams as a beam for subsequent downlink signal transmission. Meanwhile, the network device may also adopt the same beam to send multiple same signals, and the terminal device adopts different beams to receive the multiple signals, thereby selecting the beam with the optimal receiving quality as a beam for subsequent signal receiving.

    [0016] Therefore, during both of uplink transmission and downlink transmission, a receiver is required to know whether the same beam or different beams are adopted for multiple signals sent by a sender, so as to determine a beam used for receiving or sending a subsequent signal.

    [0017] FIG. 3 is a schematic block diagram of a signal transmission method 100 according to the invention. As illustrated in FIG. 3, the method is executed by a terminal device and, for example, may be executed by UE. The method 100 includes the following operations.

    [0018] In S110, beam indication information sent by a network device is received, the beam indication information being configured to indicate whether the same beam is adopted for transmission of N signals and N being an integer greater than 1.

    [0019] In S120, transmission of the N signals is performed with the network device according to the beam indication information.

    [0020] Specifically, the network device may predetermine whether beams for transmission of multiple signals by the terminal device or the network device are the same. The network device may further send the beam indication information to the terminal device through RRC signaling and the like and may notify the specific signals for which the same beam is adopted or specific signals for which different beams are adopted in the multiple signals to the terminal device through the beam indication information, and then the terminal device may determine how to send or receive the multiple signals according to the beam indication information. For example, the network device notifies the terminal device that, when multiple uplink signals are transmitted, the same beam may be adopted for two uplink signals therein, then the network device may adopt different beams to receive the two signals and the network device may further select an optimal beam adopted for subsequently receiving the uplink signals from the beams for receiving the two signals.

    [0021] According to the signal transmission method of the embodiment of the disclosure, it is determined whether the same beam is adopted for transmission of the multiple signals according to the beam indication information and signal transmission is performed based on the determination, so that the terminal device and the network device may determine respective optimal beams adopted for signal sending or signal receiving. Therefore, performance of subsequent signal detection is improved.

    [0022] Three points are to be noted. First, descriptions are made in the embodiment of the disclosure with the condition that the network device sends the beam indication information to the terminal device to notify the terminal device whether the same beam is adopted to transmit the multiple signals. Similarly, the terminal device may also send beam indication information to the network device to notify the network device whether the same beam is adopted to transmit the multiple signals. Specifically, the beam indication information may be carried through some dedicated signaling. The disclosure is not limited thereto.

    [0023] Second, the N signals may be uplink signals and may also be downlink signals. They may be synchronization signals, may be broadcast signals such as PBCHs and System Information Blocks (SIBs), may also be PRACHs and BRSs, and may further be downlink reference signals such as CSI-RSs, DMRSs and SRSs.

    [0024] Third, transmission of the N signals with the network device refers to transmission and reception of the signals with the network device. The terminal device may receive the N signals sent by the network device, and the terminal device may also send the N signals to the network device.

    [0025] In at least one embodiment of the disclosure, the beam indication information is configured to indicate that the network device would send the N signals to a terminal device using different beams. The operation that transmission of the N signals is performed with the network device according to the beam indication information includes that: the N signals are received according to the beam indication information. The method further includes the following operation. First indication information is sent to the network device, and the first indication information is configured to indicate K signals of the N signals, 1≤K≤N and K being an integer.

    [0026] Those skilled in the art know that the BF technology may be divided into a codebook-based manner and a channel-reciprocity-based manner according to a channel information feedback manner. In the first manner, the network device determines a precoding codebook for next transmission based on codebook information fed back by a terminal. In the second manner, downlink channel information is obtained by use of channel reciprocity according to an SRS sent during uplink and a precoding matrix required by downlink is calculated and selected. When the terminal device adopts N different beams to beamform the N signals and sends the N beamformed signals to the network device, the network device may usually adopt the same beam to receive the N signals and report one or more beam indexes or an index of a CSI-RS resource corresponding to the one or more beam indexes to the terminal device. The network device may also report one or more signal indexes and the like to the terminal device for the terminal device to perform BF on a subsequent signal. Specifically, the signal index reported by the network device may be an index of the signal with the optimal signal quality in the downlink signals that is sent by the terminal device with different beams, and may also be a signal index corresponding to the second optimal signal quality or another beam index. There are no limits made thereto in the disclosure.

    [0027] In at least one embodiment of the disclosure, the beam indication information is configured to indicate the terminal device to send the N signals to the network device using different beams. The operation that transmission of the N signals is performed with the network device according to the beam indication information includes that: the N signals are sent according to the beam indication information. The method further includes the following operation. Second indication information sent by the network device is received, and the second indication information is configured to indicate L signals of the N signals, 1≤L≤N and L being an integer.

    [0028] When the network device adopts N different beams to beamform the N signals and sends the N beamformed signals to the terminal device, the terminal device may usually adopt the same beam to receive the N signals and report one or more beam indexes or an index of a CSI-RS resource corresponding to the one or more beam indexes to the network device. The terminal device may also report one or more signal indexes and the like to the network device for the network device to perform BF on a subsequent signal. Specifically, the signal index reported by the terminal device may be an index of the signal with the optimal signal quality in the downlink signals that is sent by the network device with different beams, and may also be a signal index corresponding to the second optimal signal quality or another beam index. There are no limits made thereto in the disclosure.

    [0029] Furthermore, the terminal device, after sending the multiple signals by using different beams, may further determine a beam used for sending a subsequent signal according to the second indication information. Specifically, the terminal device determines a beam used for sending a signal indicated by the second indication information according to the received second indication information and determines the determined beam as the beam used for sending the subsequent signal.

    [0030] In at least one embodiment of the disclosure, the beam indication information is configured to indicate that the network device would send the N signals to the terminal device using the same beam. The operation that transmission of the N signals is performed with the network device according to the beam indication information includes that: different beams are adopted to receive the N signals according to the beam indication information. The method further includes the following operation. A beam used for receiving a subsequent signal is determined from the beams for receiving the N signals.

    [0031] Similarly, when the terminal device determines according to the beam indication information that the network device adopts the same beam to send the multiple signals to the terminal device, the network device may adopt different beams to receive the multiple beamformed signals and determine the beams adopted for the signal with the optimal receiving quality in the multiple signals, thereby determining the specific beams subsequently adopted to receive the signal with the optimal signal quality. It is to be understood that there may be one or more signals with the optimal receiving quality. There are no limits made thereto in the disclosure.

    [0032] In at least one embodiment of the disclosure, the beam indication information is configured to indicate the terminal device to send the N signals to the network device using the same beam. The operation that transmission of the N signals is performed with the network device according to the beam indication information includes the following action. The N signals are sent by using the same beam according to the beam indication information.

    [0033] Similarly, when the terminal device determines according to the beam indication information that the terminal device adopts the same beam to send the multiple signals, the terminal device may adopt the same beam to transmit the multiple signals. The network device may adopt different beams to receive the multiple signals, and the network device may determine the beams adopted for the signal with the optimal receiving quality in the multiple signals, thereby determining the specific beams subsequently adopted to receive the signal with the optimal signal quality. It is to be understood that there may be one or more signals with the optimal receiving quality. There are no limits made thereto in the disclosure.

    [0034] It is to be understood that the abovementioned embodiment is only a schematic description and should not limit the embodiment of the disclosure. For example, when the terminal device determines according to the beam indication information that the terminal device should send the multiple signals to the network device by using different beams, the terminal device may adopt different beams to send the multiple signals to the network device, and the terminal device may also adopt the same beam to send the multiple signals to the network device. The terminal device may determine the beam indication information as reference information and send or receive the multiple signals according to its own condition.

    [0035] It is also to be understood that the N signals in the embodiment may not only include uplink signals but also include downlink signals. That is, the beam indication information may indicate that the same or different beams are adopted for the uplink signals in the N signals and may also indicate that the same or different beams are adopted for the downlink signals in the N signals. The embodiment of the disclosure is not limited to a scenario that the N signals only refer to uplink signals or downlink signals.

    [0036] In at least one embodiment of the disclosure, the beam indication information is carried in at least one of the following signaling or signals: RRC signaling, MAC signaling, DCI signaling, a downlink synchronization signal, a downlink random access signal or a downlink pilot signal.

    [0037] Specifically, the beam indication information is transmitted through the RRC signaling or the MAC signaling or the DCI signaling, or the beam indication information is carried in a downlink signal. For example, the beam indication information may be carried in a Primary Synchronization Signal (PSS) or a Secondary Synchronization Signal (SSS) or a PBCH. The beam indication information may also be implicitly indicated through other information in DCI. The beam indication information may further be sent to the terminal device together with transmission resource configuration information for the multiple signals. For example, when the transmission resource configuration information for the multiple signals is configured through RRC signaling, the beam indication information may be sent or received together with the transmission resource configuration information in the same RRC information field. A beam indication signal may also be carried through some dedicated downlink control signals.

    [0038] Furthermore, the MAC signaling carrying the beam indication information is configured to activate or deactivate the N signals; and/or, when the N signals are reference signals, the DCI signaling carrying the beam indication information is configured to trigger the N signals, and when the N signals are channels, the DCI signaling carrying the beam indication information is configured to schedule the N signals. For example, when a CSI-RS resource is activated through the MAC signaling, the beam indication information may be carried through the MAC signaling.

    [0039] In at least one embodiment, the DCI signaling triggering or scheduling the multiple signals and/or the MAC signaling activating or deactivating the multiple signals may also not carry the beam indication information. The beam indication information is carried in other signaling such as the RRC signaling. The embodiment of the disclosure is not limited thereto.

    [0040] It is to be understood that when the beam indication information and the transmission resource configuration information corresponding to the multiple signals are transmitted together, the multiple signals may be the same type of signals with different transmission resource configurations or different types of signals with different transmission resource configurations. For example, the multiple signals are pilot signals of the same type or channels of the same type. For example, all of the multiple signals are PRACH signals, or SRSs, or DMRSs, or CSI-RSs, or BRSs, or synchronization signals, or Physical Downlink Shared Channel (PDSCH) signals, or PBCH signals, or Physical Uplink Shared Channel (PUSCH) signals.

    [0041] In at least one embodiment of the disclosure, the beam indication information includes beam information in one-to-one correspondence with each signal in the N signals, and the beam indication information indicates whether the same beam is adopted for the N signals through at least one of the followings. When contents indicated by beam information for a first signal and a second signal in the N signals are the same, the same beam is adopted to transmit the first signal and the second signal; when contents indicated by beam information for a third signal and a fourth signal in the N signals are different, different beams are adopted to transmit the third signal and the fourth signal; when beam information for a fifth signal and a sixth signal in the N signals is a first preconfigured value (for example, the first value may be 0), the same beam is adopted to transmit the fifth signal and the sixth signal; when beam information for a seventh signal and an eighth signal in the N signals is a second preconfigured value (for example, the second value may be 1), different beams are adopted to transmit the seventh signal and the eighth signal, the first value being different from the second value; when a content indicated by beam information for a ninth signal in the N signals includes an index of a tenth signal in the N signals, the same beam is adopted to transmit the ninth signal and the tenth signal; or when a content indicated by the beam information for an eleventh signal in the N signals includes an index of a twelfth signal in the N signals, different beams are adopted to transmit the eleventh signal and the twelfth signal.

    [0042] Specifically, the beam indication information may be a bit table. In the bit table, each bit corresponds to a signal in the multiple signals and each bit represents the beam information adopted for the signal. For example, eight bits are adopted to represent eight signals. It may be predetermined that the same beam is adopted for the signals corresponding to the bits 0 and different beams are adopted for the signals corresponding to the bits 1. It may also be predetermined that the same beam is adopted for the signals corresponding to the bits 1 and different beams are adopted for the signals corresponding to the bits 0. For another example, in the eight pieces of beam information included in the beam indication information, when a content indicated by a certain piece of beam information includes an index of another signal, it may be predetermined that the same beam is adopted for the two signals and it may also be predetermined that different beams are adopted for the two signals. It is to be understood that the above is only exemplary description and not intended to limit the scope of protection of the embodiment of the disclosure.

    [0043] FIG. 4 is a schematic block diagram of a signal transmission method 200 not being part of the invention. The method 200 may be executed by a network device and, for example, may be executed by a base station. As illustrated in FIG. 4, the method 200 includes the following operations.

    [0045] In S220, transmission of the N signals is performed with the terminal device.

    [0046] According to the signal transmission method of the embodiment of the disclosure, the network device sends the beam indication information used for determining whether the same beam is adopted for transmission of the multiple signals to the terminal device, so that the terminal device and the network device may determine respective optimal beams adopted for signal sending or signal receiving. Therefore, performance of subsequent signal detection is improved.

    [0047] In at least one embodiment of the disclosure, the beam indication information is configured to indicate that a network device would send the N signals to the terminal device using different beams.

    [0059] It is to be understood that interaction with the terminal device and related characteristics, functions and the like described in the signal transmission method for a network device side correspond to related characteristics and functions of the signal transmission method for a terminal device side and will not be elaborated herein for simplicity.

Specifically, the same beam is adopted for the CSI-RSs corresponding to the CSI-RS resources configured with the same indication information and different beams are adopted for the CSI-RSs corresponding to the CSI-RS resources configured with different indication information. For example, when N=4, the beam indication information corresponding to a CSI-RS resource 0 and a CSI-RS resource 2 indicate 0, the beam indication information for a CSI-RS resource 1 indicates 1 and the beam indication information for a CSI-RS resource 3 indicates 2, it is indicated that the same beam (recorded as Beam 1) is used for transmitting the CSI-RSs corresponding to the resource 0 and the resource 2, a different beam (recorded as Beam 2) is used for transmitting the CSI-RS corresponding to the resource 1 and another different beam (recorded as Beam 3) is used for transmitting the CSI-RS corresponding to the resource 3. The CSI-RSs sent by the same beam may be configured for determining downlink receiving beams, and the CSI-RSs sent by different beams may be configured for determining downlink sending beams.

    [0062] Embodiment 2: a network-side device configures N SRSs resources and allocates 1-bit beam indication information for each SRS resource. The beam indication information is indicated together with resource configuration information of each SRS resource. A terminal determines whether the same beam is adopted for different SRSs according to the beam indication information of each SRS resource. Specifically, the same beam is adopted for the SRSs corresponding to the SRS resources configured with indication information 0 and different beams are adopted for the SRSs corresponding to the SRS resources configured with indication information 1. For example, when N=8, the beam indication information corresponding to the SRS resources {0, 1, 2, 3} indicates 0 and the beam indication information corresponding to the SRS resources {4, 5, 6, 7} indicates 1, the same beam (recorded as Beam 1) is used for transmitting the SRSs corresponding to the SRS resources {0, 1, 2, 3} and different beams (recorded as Beam 2, Beam 3, Beam 4 and Beam 5) are used for transmitting the SRSs corresponding to the SRS resources {4, 5, 6, 7). The SRSs sent by the same beam may be configured for determining uplink receiving beams, and the SRSs sent by different beams may be configured for determining uplink sending beams. The same method may also be applied to PRACH transmission.

    [0063] Embodiment 3: a network-side device configures N CSI-RS resources in advance through RRC signaling and triggers a terminal through downlink DCI to perform aperiodic CSI-RS measurement based on K CSI-RS resources in the N CSI-RS resources, K being an integer less than or equal to N. The DCI contains 1-bit beam indication information. When the indication information indicates 0, it is indicated that the same beam is used for transmitting CSI-RSs corresponding to the K triggered CSI-RS resources. When the indication information indicates 1, it is indicated that different beams are used for the CSI-RSs corresponding to the K triggered CSI-RS resources. The CSI-RSs sent by the same beam may be configured for determining downlink receiving beams and the CSI-RSs sent by different beams may be configured for determining downlink sending beams.

    [0064] Embodiment 4: a network-side device triggers a terminal to perform aperiodic SRS transmission through DCI, and every time when the terminal is triggered, N SRSs are required to be repeatedly sent. For the N SRSs, the same frequency-domain resource/sequence may be adopted and different frequency-domain resources/sequences may also be adopted. The DCI contains 1-bit beam indication information. When the indication information indicates 0, it is indicated that the same beam is used for transmitting the N triggered SRSs. When the indication information indicates 1, it is indicated that different beams are used for the N triggered SRSs. The SRSs sent by the same beam may be configured for determining uplink receiving beams and the CSI-RSs sent by different beams may be configured for determining uplink sending beams.

    [0065] Embodiment 5: during downlink synchronization signal transmission, beam indication information may be carried through a PSS sequence or an SSS sequence or a PRACH. A PSS is taken as an example herein. Different PSS sequences may be adopted to implicitly indicate the beam indication information. That is, different information corresponds to different PSS sequences. For example, information 0 corresponds to a PSS sequence 1 and information 1 corresponds to a PSS sequence 2. Such a correspondence may be predetermined. The terminal performs blind detection on the PSS sequences to obtain the information corresponding to each PSS sequence, and then determines whether the same beam is adopted for multiple PSS sequences according to the information. Two determination methods may specifically be adopted. The information 0 indicates that the same beam is used for transmitting a plurality of corresponding PSS sequences and the information 1 indicates that different beams are used for transmitting a plurality of corresponding PSS sequences. N different PSS sequences are used to correspond to N different beam indication information, the same beam is used for the PSS sequences with the same beam indication information and different beams are used for the PSS sequences with different beam indication information. For example, when the beam indication information is K, it is indicated that a Kth beam is used for transmitting a PSS sequence.
