Description

TECHNICAL FIELD



[0001] Embodiments of the application relate to the field of communications, and more particularly to a bandwidth allocation method and device.

BACKGROUND



[0002] For reducing power consumption of a terminal device, a Discontinuous Reception (DRX) transmission mechanism is introduced into a Long Term Evolution (LTE) system. When no data is transmitted, the terminal device may stop receiving a Physical Downlink Control Channel (PDCCH) to reduce power consumption, thereby prolonging life of a battery. A DRX cycle is configured by the DRX transmission mechanism for a terminal device in a Radio Resource Control (RRC) connected state. The DRX cycle consists of an On Duration and an Opportunity for DRX. Within the On Duration, the terminal device monitors and receives a PDCCH. Within the Opportunity for DRX, the terminal device does not receive any PDCCH and thus the power consumption is reduced.

[0003] Within the On Duration, the terminal device may usually open the whole radio frequency bandwidth for data transmission. However, in a New Radio (NR) system, a terminal device may support a radio frequency bandwidth of hundreds of MHz, and if the terminal device still opens the whole radio frequency bandwidth when the volume of transmitted data is small, unnecessary power consumption may be brought.

[0004] Therefore, a bandwidth allocation method is needed to avoid unnecessary power consumption of a terminal device.

DETAILED DESCRIPTION



[0015] The technical solutions in the embodiments of the application will be clearly and completely described below in combination with the drawings in the embodiments of the application.

[0016] It is to be understood that the technical solutions of the embodiments of the application may be applied to various communication systems, for example, a Global System of Mobile communication (GSM), a Code Division Multiple Access (CDMA) system, a Wideband Code Division Multiple Access (WCDMA) system, a General Packet Radio Service (GPRS), an LTE system, an LTE Frequency Division Duplex (FDD) system, an LTE Time Division Duplex (TDD) system, a Universal Mobile Telecommunication System (UMTS) or a Worldwide Interoperability for Microwave Access (WiMAX) communication system, a 5th-Generation (5G) system or an NR system.

[0017] In the embodiments of the application, a terminal device may include, but not limited to, a Mobile Station (MS), a mobile terminal, a mobile telephone, User Equipment (UE), a handset, portable equipment, a vehicle and the like. The terminal device may communicate with one or more core networks through a Radio Access Network (RAN). For example, the terminal device may be a mobile phone (or called a "cell" phone), a computer with a wireless communication function and the like. The terminal device may also be a portable, pocket, handheld, computer-embedded or vehicle-mounted mobile device.

[0018] A network device involved in the embodiments of the application is a device deployed in a RAN to provide a wireless communication function for a terminal device. The network device may be a base station, and the base station may include macro base stations, micro base stations, relay stations, access points and the like in various forms. In systems adopting different radio access technologies, a device with a base station function may have different names, for example, it is called an Evolved NodeB (eNB or eNodeB) in an LTE network, and is called a Node B in a 3rd-Generation (3G) network, etc.

[0019] FIG. 1 illustrates a bandwidth allocation method according to an embodiment of the application. As shown in FIG. 1, the method 100 includes the following operations.

[0020] In S110, DRX indication information is determined, the DRX indication information being used for a terminal device to determine a working bandwidth to be used within a DRX cycle and/or a frequency point of the working bandwidth.

[0021] In S120, the DRX indication information is transmitted to the terminal device.

[0022] It is to be noted that the working bandwidth in S110 may include a transmitting bandwidth and a receiving bandwidth.

[0023] It is also to be noted that the bandwidth (not 0MHz) determined by the terminal device according to the DRX indication information in S110 is a default working bandwidth of the terminal device within a DRX On Duration. On such a basis, a network device may also determine the working bandwidth to be used by the terminal device within a DRX cycle according to a data volume required to be transmitted by the terminal device within the cycle. Under the condition that the data volume required to be transmitted by the terminal device is relatively large, the network device may usually determine a relatively large working bandwidth for the terminal device, to ensure rapid transmission of the terminal device. Under the condition that the data volume required to be transmitted by the terminal device is relatively small, the network device may determine a relatively small working bandwidth for the terminal device, to reduce power consumption of the terminal device.

[0024] The DRX indication information in S110 directly indicates the working bandwidth to be used by the terminal device within the DRX cycle and/or the frequency point of the working bandwidth. In such case, the DRX indication information may indicate that the working bandwidth to be used by the terminal device within the DRX cycle is 0MHz. If the working bandwidth indicated by the DRX indication information is 0MHz, it is indicated that the terminal device has no service to be transmitted within a next DRX On Duration, and then the terminal device is not required to monitor a PDCCH within the DRX On Duration.

[0025] If a system bandwidth is divided into multiple bandwidth parts, the network device and the terminal device may predetermine multiple types of bandwidth-part allocations and a bandwidth-part allocation index number of each bandwidth-part allocation. Or, the network device may notify the terminal device of the multiple types of bandwidth-part allocations and the bandwidth-part allocation index number of each bandwidth-part allocation through broadcast signaling or RRC signaling. The DRX indication information in S110 may directly indicate a bandwidth-part allocation index number, and the terminal device may learn the bandwidth-part allocation required to be adopted according to the bandwidth-part allocation index number indicated by the DRX indication information. For example, the DRX indication information is carried in Downlink Control Information (DCI) on a PDCCH, and the DRX indication information includes K information bits, and can indicate 2K index numbers of working-bandwidth allocations to correspond to 2K bandwidth-part allocations, a value of K being determined by the number of the bandwidth-part allocations.

[0026] Or, the network device may transmit first allocation information to the terminal device, the first allocation information including at least one of the following corresponding relationships: a corresponding relationship between a time-frequency resource used to carry the DRX indication information and the bandwidth-part allocation index number indicated by the DRX indication information, a corresponding relationship between an orthogonal sequence used to generate the DRX indication information and the bandwidth-part allocation index number indicated by the DRX indication information, a corresponding relationship between a cyclic shift adopted for the orthogonal sequence used to generate the DRX indication information and the bandwidth-part allocation index number indicated by the DRX indication information, or a corresponding relationship between indication states of multiple pieces of DRX indication sub information used to form the DRX indication information and the bandwidth-part allocation index number indicated by the DRX indication information.

[0027] For example, if there are M bandwidth-part allocations, M bandwidth-part allocation index numbers and M time-frequency resource positions used to carry the DRX indication information, the first allocation information includes a one-to-one corresponding relationship between the M time-frequency resource positions used to carry the DRX indication information and the M bandwidth-part allocation index numbers indicated by the DRX indication information, and/or the first allocation information includes a one-to-one corresponding relationship between M orthogonal sequences configured to generate the DRX indication information and the M bandwidth-part allocation index numbers indicated by the DRX indication information, and/or the first allocation information includes a one-to-one corresponding relationship between M cyclic shifts adopted for the orthogonal sequences configured to generate the DRX indication information and the M bandwidth-part allocation index numbers indicated by the DRX indication information, and/or, if the DRX indication information consists of multiple pieces of DRX indication sub information at multiple time-frequency resource positions, the first allocation information may include a one-to-one corresponding relationship between different combinations of indication states of the multiple pieces of DRX indication sub information and the bandwidth-part allocation index numbers indicated by the DRX indication information. For example, the DRX indication information at each time-frequency resource position has two indication states (for example, transmitting DRX indication sub information on one time-frequency resource represents an indication state "1" and not transmitting DRX indication sub information on the time-frequency resource represents a state "0"), the indication states of the DRX indication sub information at N time-frequency resource positions form 2N different states to indicate at most 2N bandwidth-part allocation index numbers, namely to indicate at most 2N bandwidth-part allocations. For example, if a value of N is 3, totally eight indication states "000", "001", "010", "011", "100", "101", "110" and "111" can be formed to indicate eight bandwidth-part allocations respectively.

[0028] Correspondingly, the terminal device, after receiving the DRX indication information, may determine the bandwidth-part allocation index number indicated by the DRX indication information according to the time-frequency resource where the DRX indication information is received and the first allocation information. Or, the terminal device may determine the bandwidth-part allocation index number indicated by the DRX indication information according to the orthogonal sequence adopted for the received DRX indication information and the first allocation information. Or, the terminal device may determine the bandwidth-part allocation index number indicated by the DRX indication information according to the cyclic shift for the orthogonal sequence adopted for the received DRX indication information and the first allocation information. Or, the terminal device may determine the bandwidth-part allocation index number indicated by the DRX indication information according to the indication states of the multiple pieces of DRX indication sub information in the received DRX indication information and the first allocation information. After the bandwidth-part allocation index number indicated by the DRX indication information is determined, the bandwidth-part allocation required to be adopted can be learned.

[0029] Optionally, as an example, each bandwidth-part allocation is configured to indicate the number of bandwidth parts and/or center frequency points of the bandwidth parts, and different bandwidth-part allocations may indicate different numbers of bandwidth parts and/or center frequency points of the bandwidth parts. In such case, the terminal device may learn the bandwidth-part allocation required to be adopted to know the number of available bandwidth parts and/or the center frequency points of the bandwidth parts, and the terminal may determine the working bandwidth to be used within the DRX cycle according to a bandwidth of each bandwidth part and the number of the bandwidth parts, and may determine the frequency point of the working bandwidth to be used within the DRX cycle according to the center frequency points of the bandwidth parts.

[0030] Optionally, as another example, each bandwidth-part allocation is configured to indicate a bandwidth size of a bandwidth part and/or a center frequency point of the bandwidth part. In such case, the terminal device may learn the bandwidth-part allocation required to be adopted to know an available working bandwidth and/or a center frequency point of the working bandwidth. Moreover, the terminal device may determine one or more bandwidth parts where to work according to the bandwidth of each bandwidth part and the bandwidth size, indicated by the bandwidth-part allocation, of the bandwidth part.

[0031] Each bandwidth-part allocation is configured to indicate a bandwidth part available for the terminal device. In such case, the terminal device may learn the bandwidth part required to be adopted to determine the working bandwidth to be used within the DRX cycle and the frequency point of the working bandwidth. For example, as shown in Table 1, if there are four bandwidth parts, i.e., a bandwidth part 0, a bandwidth part 1, a bandwidth part 2 and a bandwidth part 3 respectively, and when the DRX indication information indicates that the bandwidth-part allocation index number is 0, the terminal device determines to use the bandwidth part 0. When the DRX indication information indicates that the bandwidth-part allocation index number is 3, the terminal device determines to use the bandwidth part 0 or the bandwidth part 1.

0 Bandwidth part 0
1 Bandwidth part 1
2 Bandwidth part 2
3 Bandwidth part 0/1
4 Bandwidth part 1/2
5 Bandwidth part 0/1/2


[0032] Optionally, the four bandwidth parts may be obtained in a manner that the network device divides a system bandwidth according to a method shown in FIG. 2. In FIG. 2, the four bandwidth parts have different center frequency points, and may further have different bandwidths. Or, the four bandwidth parts may be obtained in a manner that the network device divides a system bandwidth according to a method shown in FIG. 3. In FIG. 3, the bandwidth part 0 and the bandwidth part 1 are at a high-frequency end of the system bandwidth and have the same center frequency point but different bandwidth sizes, and the bandwidth part 2 and the bandwidth part 3 are at a low-frequency end of the system bandwidth and have the same center frequency point but different bandwidth sizes.

[0033] Specifically, in some embodiments, under the condition that the bandwidth parts are divided by adopting the method shown in FIG. 3, the bandwidth-part allocation may be used to indicate a bandwidth size of a bandwidth part and/or a center frequency point of the bandwidth part, and the terminal device may determine the specific bandwidth part where it is required to work according to the bandwidth-part allocation. For example, if a bandwidth of the bandwidth part 0 in FIG. 3 is 10MHz, a bandwidth of the bandwidth part 1 is 20MHz, a bandwidth of the bandwidth part 2 is 15MHz, a bandwidth of the bandwidth part 3 is 30MHz and the bandwidth size, indicated by the bandwidth-part allocation, of the bandwidth part is 20MHz, the terminal device may determine that the working bandwidth is 20MHz and a center frequency point of the working bandwidth is the center frequency point of the bandwidth part 1.

[0034] It can be understood that the network device and the terminal device may predetermine a bandwidth-part division method and the network device may also notify the terminal device of the bandwidth-part division method through allocation information, the allocation information specifically indicating allocation information of the bandwidth and/or center frequency point of each bandwidth part.

[0035] In the embodiment of the application, if the system bandwidth is divided into multiple bandwidth parts, the network device may transmit second allocation information to the terminal device, the second allocation information including at least one of the following corresponding relationships: a corresponding relationship between a time-frequency resource used to carry the DRX indication information and a bandwidth part, a corresponding relationship between a orthogonal sequence used to generate the DRX indication information and the bandwidth part, a corresponding relationship between a cyclic shift adopted for the orthogonal sequence used to generate the DRX indication information and the bandwidth part, or a corresponding relationship between the indication states of the multiple pieces of DRX indication sub information used to form the DRX indication information and the bandwidth part.

[0036] Correspondingly, the terminal device, after receiving the DRX indication information, directly determines an available bandwidth part according to the time-frequency resource where the DRX indication information is received and the second allocation information. Or, the terminal device directly determines an available bandwidth part according to the orthogonal sequence adopted for the received DRX indication information and the second allocation information. Or, the terminal device directly determines an available bandwidth part according to the cyclic shift for the orthogonal sequence adopted for the received DRX indication information and the second allocation information. Or, the terminal device directly determines an available bandwidth part according to the indication states of the multiple pieces of DRX indication sub information in the received DRX indication information and the second allocation information. The terminal device, after determining the available bandwidth part, may know the available working bandwidth and/or the frequency point of the working bandwidth.

[0037] In the embodiment of the application, for each DRX cycle or every L DRX cycles, L being a positive integer greater than 1, the network device determines, according to an instantaneous service condition of the terminal device, a bandwidth-part allocation which is used by the terminal device within the DRX cycle. For example, if the terminal device has a relatively large downlink service packet arriving, the network device may adopt the DRX indication information to instruct the terminal device to use a relatively large number of bandwidth parts or a bandwidth part with a relatively large bandwidth for transmission within an On Duration of the DRX cycle, to ensure rapid service transmission of the terminal device. Otherwise, if the terminal device only has a relatively small downlink service packet arriving, the network device may adopt the DRX indication information to instruct the terminal device to use a relatively small number of bandwidth parts or a bandwidth part with a relatively small bandwidth for transmission within the DRX On Duration.

[0038] Optionally, in S120, the network device sends the DRX indication information to the terminal device at a starting moment of the DRX cycle, or sends the DRX indication information to the terminal device on an early subframe (for example, a first subframe) within the On Duration of the DRX cycle.

[0039] The bandwidth allocation method according to the embodiments of the application is described above from a network device side in combination with FIG. 1 to FIG. 3 in detail. A bandwidth allocation method according to the embodiments of the application will be described below from a terminal device side in combination with FIG. 4 in detail.
