Description

Technical Field



[0001] Embodiments of the present application relate to a field of wireless communication, and more particularly relate to a method for transmitting data and a terminal device.

Background



[0002] In a 5G system, both grant-based uplink transmission and grant-free uplink transmission are supported. For the grant-based uplink transmission, a base station may send Uplink Grant (UL Grant) to a terminal device to schedule transmission of a physical uplink channel; for the grant-free uplink transmission, a terminal device may directly perform uplink transmission by using a pre-configured resource without waiting for scheduling by a base station.

[0003] When a terminal device supports the grant-based uplink transmission and the grant-free uplink transmission, if UL Grant is received on a same time domain resource, and there is a resource for the grant-free transmission, the terminal device may not effectively transmit data.

Summary



[0004] Embodiments of the present application provide a method for transmitting data and a terminal device, the terminal device may effectively select an appropriate transmission mode so as to transmit data based on grant-free transmission in a resource scheduled by a network device or a resource used for the grant-free transmission.

[0005] In a first aspect, a method for transmitting data is provided. The method includes: receiving, by a terminal device, a first signaling, wherein the first signaling indicates the terminal device to transmit a first physical uplink channel on a first resource; determining, by the terminal device, whether a transmission parameter used for transmitting the first physical uplink channel satisfies a preset condition; carrying, by the terminal device, data of a first type on the first physical uplink channel for transmission when the transmission parameter satisfies the preset condition, and the data of the first type is data based on grant-free transmission.

[0006] Therefore, the terminal device judges a resource scheduled by the network device to determine whether data based on grant-free transmission to be transmitted is transmitted in the resource scheduled by the network device or in the resource used for grant-free transmission, so that the terminal device can flexibly select the resource when receiving uplink grant information and a resource available for grant-free transmission has already existed, so as to effectively transmit the data, thereby satisfying a service transmission requirement of low delay and high reliability.

[0007] In a possible implementation, the first resource is a resource for transmitting data of a second type, and the data of the second type is data of grant-based transmission.

[0008] For example, the first signaling may be uplink grant (UL Grant) information sent by the network device to the terminal device to schedule the terminal device to use the resource indicated by the uplink grant information to send data. The resource indicated by the uplink grant information may include resource information, such as, a time-frequency domain resource, reference symbol information, a modulation and coding scheme, a power control parameter.

[0009] In a possible implementation, the transmission parameter of the first physical uplink channel include at least one of following: a number of bits of data carried on the first physical uplink channel, a transmission block size (TBS) of data carried on the first physical uplink channel, a position of a starting time domain symbol of the first resource, a position of an ending time domain symbol of the first resource, a time domain length occupied by the first physical uplink channel, and whether the data of the second type carried on the first physical uplink channel is data transmitted for a first time.

[0010] Here, the number of bits of the data carried on the first physical uplink channel refers to a number of bits of data originally expected to be scheduled by the network device, that is, the number of bits of data carried on the first physical uplink channel indicated by the first signaling; the TBS of the data carried on the first physical uplink channel refers to a TBS of data originally expected to be scheduled by the network device, that is, a TBS of data carried on the first physical uplink channel indicated by the first signaling; whether the data of the second type carried on the first physical uplink channel is the data transmitted for the first time refers that whether data of a second type originally expected to be scheduled by the network device is the data transmitted for the first time.

[0011] In a possible implementation, the method further includes:, carrying, by the terminal device, the data of the first type on a second physical uplink channel when the transmission parameter does not satisfy the preset condition, wherein the second physical uplink channel is a physical uplink channel transmitted on a second resource.

[0012] Specifically, when the terminal device determines that the transmission parameter of the first physical uplink channel does not satisfy the preset condition, the terminal device will select the second physical uplink channel from the second resource used for transmitting the date of the first type and carry the data of the first type to be transmitted on the second physical uplink channel for transmission. When the terminal device determines that the transmission parameter of the first physical uplink channel satisfies the preset condition, the terminal device may carry the data of the first type to be transmitted on the first physical uplink channel indicated by the first signaling for transmission.

[0013] In a possible implementation, the method further includes: not transmitting, by the terminal device, the first physical uplink channel.

[0014] In a possible implementation, when a total power used for simultaneously transmitting the first physical uplink channel and the second physical uplink channel is limited, the method further includes: not transmitting, by the terminal device, the first physical uplink channel; or reducing, by the terminal device, a power used for transmitting the first physical uplink channel, and using, by the terminal device, a reduced power to transmit the first physical uplink channel.

[0015] That is, when the transmission parameter of the first physical uplink channel does not satisfy the preset condition, the terminal device will use the second physical uplink channel in the second resource to transmit the data of the first type. In this case, in order to preferentially ensure normal transmission of the data of the first time, the terminal device may temporarily not transmit the first physical uplink channel, or transmit the first physical uplink channel with a lower power.

[0020] In a possible implementation, the first length relationship includes any one of following: the time domain length of the first physical uplink channel is equal to the time domain length of the second physical uplink channel; a difference between the time domain length of the first physical uplink channel and the time domain length of the second physical uplink channel is greater than or equal to a fifth threshold and less than or equal to a sixth threshold.

[0032] Various embodiments are described herein in connection with network devices in the present application. A network device may be a device for communicating with a terminal device, such as a Base Transceiver Station (BTS) in a GSM system or CDMA, a NodeB (NB) in a WCDMA system, or an Evolutional Node B (eNB or eNodeB) in an LTE system, or the network device may be a relay station, an access point, a vehicle-mounted device, a wearable device, a network side device in a future 5G network, or a network side device in a future evolved PLMN network, etc.

[0033] FIG. 1 is a schematic diagram of an application scenario of an embodiment of the present application. A communication system in FIG. 1 may include a network device 10 and a terminal device 20. The network device 10 is configured to provide a communication service for the terminal device 20 and access to a core network. The terminal device 20 may access a network by searching for a synchronization signal, or a broadcast signal, etc., transmitted by the network device 10, to communicate with the network. Arrows shown in FIG. 1 may represent uplink/downlink transmission through cellular links between the terminal device 20 and the network device 10.

[0034] A network in an embodiment of the present application may refer to a Public Land Mobile Network (PLMN) or a device-to-device (D2D) network or a machine-to-machine/man (M2M) network or other networks. FIG. 1 is a simplified schematic diagram of an example, and other terminal devices may be included in the network and are not shown in FIG. 1.

[0035] In a 5G system, many special service types, such as low latency and high reliability services (URLLC) are introduced. Characteristic of the URLLC service is to realize ultra-high reliability (e.g. 99.999%) transmission within a very short (e.g. 1ms) delay. In order to achieve this goal, a grant-free transmission is proposed to satisfy a requirement of low delay and high reliability service transmission. Those skilled in the art may know that the grant-free transmission may also be called other names, such as unscheduled transmission, non-scheduled transmission, unauthorized transmission, etc.

[0036] In an embodiment of the present application, the data may include service data or signaling data. A transmission resource used for the grant-free transmission may include, but not limited to, one or a combination of following resources: a time domain resource, such as a radio frame, a subframe, a symbol; a frequency domain resource, such as a subcarrier, a resource block; a space domain resource, such as a transmitting antenna, a beam; a code domain resource, such as a Sparse Code Multiple Access (referred to as "SCMA") code group, a Low Density Signature (referred to as "LDS") group, a CDMA code group, an uplink pilot resource; an interleaved resource; a channel coding scheme.

[0037] The above transmission resource may be used for transmissions according to control mechanisms including, but not limited to, uplink power control, such as an upper limit control of uplink transmission power; a modulation coding scheme configuration, such as transmission block size configuration, code rate configuration, and a modulation order configuration; a retransmission mechanism, such as HARQ mechanism, etc.

[0038] The grant-free transmission adopts a pre-configured or semi-continuous resource configuration mode. When a terminal device has uplink data to transmit, a pre-configured resource may be used to directly transmit uplink data without waiting for scheduling by a base station. The grant-free transmission avoids processes of Schedule Request (SR) and Buffer Status Report (BSR) and increases effective transmission time of the terminal device.

[0039] At present, the grant-free transmission configuration may have two types, namely Type 1 and Type 2. In the Type1, a resource used for the grant-free transmission is semi-statically configured by using a Radio Resource Control (RRC) signaling, the resource at least includes a time-frequency domain resource, reference symbol information, a modulation and coding scheme, a power control parameter, etc. In Type2, a resource used for the grant-free transmission is semi-statically configured or dynamically activated or deactivated by using a way of a combination of a RRC signaling and a physical layer signaling, and the resource configured by the RRC signaling at least include a time domain resource period and a power control parameter, etc., and the resource configured by the physical layer signaling at least include a frequency domain resource, reference symbol information and a modulation and code scheme, etc.

[0040] In addition, in a 5G system, transmission of grant-based uplink data is still supported. When the terminal device supports a transmission mode based on base station scheduling, that is, the base station transmits UL grant to the terminal device to schedule data transmission, and also supports a transmission mode based on the grant-free transmission, since the base station may not predict a transmission situation of data of the grant-free transmission, therefore, for the terminal device that supports both grant-free and grant-based transmission, on a same time domain resource, the terminal device not only receives the corresponding information of a resource scheduled through UL grant, but also has a resources that may be used for grant-free transmission, the terminal device does not know which resource to use, then the transmission of data can not effectively be performed.

[0041] In An embodiment of the present application, a resource scheduled by the network device is judged to determine whether the data to be transmitted based on the grant-free transmission is transmitted in the resource scheduled by the network device or in the resource available for the grant-free transmission. Since high reliability and efficiency is obtained by using the resource scheduled by the network device to transmit data, when the terminal device receives uplink grant information and there is data to be transmitted based on the grant-free transmission, the terminal device can use a more reliable and effective way to transmit data, thus satisfying a service transmission requirement of low delay and high reliability.

[0042] FIG. 2 is a schematic flowchart of a method for transmitting data according to an embodiment of the present application. The method shown in FIG. 2 may be performed by a terminal device, which may be, for example, the terminal device 20 shown in FIG. 1. As shown in FIG. 2, the method for transmitting data includes acts 210-220.

[0043] In act 210, the terminal device receives a first signaling, wherein the first signaling is used for indicating the terminal device to transmit a first physical uplink channel on a first resource.

[0044] Optionally, the first resource is a resource for transmitting data of a second type, the data of the second type is data of grant-based transmission.

[0045] For example, the first signaling may be uplink grant information sent by a network device to the terminal device to schedule the terminal device to send data by using a resource indicated by the uplink grant information. The resource indicated by the uplink grant information may include, for example, a time-frequency domain resource, reference symbol information, a modulation and coding scheme, a power control parameter, and other resource information.

[0046] In act 220, the terminal device determines whether the transmission parameter for transmitting the first physical uplink channel satisfies a preset condition.

[0047] Optionally, the transmission parameter of the first physical uplink channel includes at least one of following: a number of bits of data carried on the first physical uplink channel, a transmission block size (TBS) of data carried on the first physical uplink channel, a position of a starting time domain symbol of the first resource, a position of an ending time domain symbol of the first resource, a time domain length occupied by the first physical uplink channel, and whether the data of the second type carried on the first physical uplink channel is data transmitted for a first time.

[0048] Here, the number of bits of data carried on the first physical uplink channel refers to a number of bits of data originally expected to be scheduled by the network device, that is, a number of bits of data carried on the first physical uplink channel indicated by the first signaling; the TBS of data carried on the first physical uplink channel refers to a TBS of data originally expected to be scheduled by network device, that is, a TBS of data carried on the first physical uplink channel indicated by the first signaling; whether the data of the second type carried on the first physical uplink channel is the data transmitted for the first time refers that whether the data of the second type originally expected to be scheduled by the network device is the data transmitted for the first time.

[0049] After act 220, the terminal device may execute acts 230 or 240. If the transmission parameter for transmitting the first physical uplink channel satisfies the preset condition, then act 230 is executed, and if the transmission parameter does not satisfy the preset condition, then act 240 is executed.

[0050] In act 230, if the transmission parameter satisfies the preset condition, the terminal device carries the data of the first type on the first physical uplink channel for transmission.

[0051] Wherein, the data of the first type is data of grant-free transmission.

[0052] In 240, if the transmission parameter does not satisfy the preset condition, the terminal device carries the data of the first type on a second physical uplink channel, the second physical uplink channel is a physical uplink channel transmitted on a second resource.

[0053] Optionally, the second resource is a resource for transmitting the data of the first type, that is, a resource used for grant-free transmission.

[0054] Herein, the terminal device may receive a second signaling used for indicating the second resource sent by the network device to obtain the second resource; or, the second resource may be pre-configured in the terminal device, that is, agreed between the terminal device and the network device in advance.

[0055] Specifically, when the terminal device determines that the transmission parameter of the first physical uplink channel does not satisfy the preset condition, the terminal device will select the second physical uplink channel from the second resource used for transmitting the data of the first type and carry the data of the first type on the second physical uplink channel for transmission.

[0056] When the terminal device determines that the transmission parameter of the first physical uplink channel satisfies the preset condition, the terminal device may carry the data of the first type to be transmitted on the first physical uplink channel indicated by the first signaling for transmission. At this case, optionally, if the number of bits of the data carried on the first physical uplink channel is greater than or equal to the number of bits of the data of the first type, or if the TBS of the data carried on the first physical uplink channel is greater than or equal to the TBS of the data of the first type, the terminal device may simultaneously carry the data of first type and the data of the second type to be transmitted on the first physical uplink channel for transmission. The data of the second type to be transmitted may be data originally expected to be scheduled by the network device.

[0057] Optionally, in act 240, when the transmission parameter does not satisfy the preset condition, the terminal device may not transmit the first physical uplink channel.

[0058] Optionally, in act 240, when the transmission parameter does not satisfy the preset condition, if a total power used for simultaneously transmitting the first physical uplink channel and the second physical uplink channel is limited, the terminal device may not transmit the first physical uplink channel; or the terminal device reduces a power for transmitting the first physical uplink channel and transmits the first physical uplink channel by using a reduced power.

[0059] That is, when the transmission parameter of the first physical uplink channel does not satisfy the preset condition, the terminal device will use the second physical uplink channel in the second resource to transmit the data of the first type. At this case, in order to preferentially ensure normal transmission of the data of the first type, the terminal device may temporarily not transmit the first physical uplink channel, or transmit the first physical uplink channel with a lower power.

[0060] Therefore, in the embodiment of the present application, the terminal device judges the resource scheduled by the network device to determine whether the data to be transmitted of the grant-free based transmission is transmitted in the resource scheduled by the network device or in the resource available for the grant-free transmission. Since high reliability and efficiency is obtained by using the resource scheduled by the network device to transmit data, when the terminal device receives uplink grant information and there is data to be transmitted based on the grant-free transmission, the terminal device may use a more reliable and effective way to transmit data, thus satisfying a service transmission requirement of low delay and high reliability.

[0061] In an embodiment of the present application, when the terminal device determines whether the transmission parameter for transmitting the first physical uplink channel satisfies the preset condition, at least one of following preset conditions may be used:

the number of bits of data carried on the first physical uplink channel is greater than or equal to the number of bits of the data of the first type;

the TBS of data carried on the first physical uplink channel is greater than or equal to the TBS of the data of the first type;

a position relationship between a position of a starting time domain symbol of the first resource and a position of a starting time domain symbol of the second resource satisfies a first position relationship;

a position relationship between a position of an ending time domain symbol of the first resource and a position of an ending time domain symbol of the second resource satisfies a second position relationship;

a length relationship between a time domain length of the first physical uplink channel and a time domain length of the second physical uplink channel satisfies a first length relationship;

the data of the second type carried on the first physical uplink channel is data transmitted for a first time.



[0062] Herein, optionally, the first position relationship includes any one of following: the position of the starting time domain symbol of the first resource is same as the position of the starting time domain symbol of the second resource; the position of the starting time domain symbol of the first resource is located before the position of the starting time domain symbol of the second resource, and a time difference between the starting time domain symbol of the first resource and the starting time domain symbol of the second resource is less than or equal to a first threshold; the position of the starting time domain symbol of the first resource is located after the position of the starting time domain symbol of the second resource; the position of the starting time domain symbol of the first resource is located after the position of the starting time domain symbol of the second resource, and an absolute value of a time difference between the starting time domain symbol of the first resource and the starting time domain symbol of the second resource is less than or equal to a second threshold.

[0063] Herein, optionally, the second position relationship includes any one of following: the position of the ending time domain symbol of the first resource is same as the position of the end time domain symbol of the second resource; the position of the ending time domain symbol of the first resource is located after the position of the ending time domain symbol of the second resource, and a time difference between the ending time domain symbol of the first resource and the ending time domain symbol of the second resource is less than or equal to a third threshold; the position of the ending time domain symbol of the first resource is located before the position of the ending time domain symbol of the second resource; the position of the ending time domain symbol of the first resource is located before the position of the ending time domain symbol of the second resource, and an absolute value of a time difference between the ending time domain symbol of the first resource and the ending time domain symbol of the second resource is less than or equal to a fourth threshold.

[0064] Herein, optionally, the first length relationship includes any one of following: the time domain length of the first physical uplink channel is equal to the time domain length of the second physical uplink channel; a difference between the time domain length of the first physical uplink channel and the time domain length of the second physical uplink channel is greater than or equal to a fifth threshold and less than or equal to a sixth threshold.

[0065] Optionally, before the terminal device determines whether the transmission parameter for transmitting the first physical uplink channel satisfies the preset condition, the method further includes: the terminal device receives indication information, wherein the indication information is used for indicating threshold information; or the terminal device acquires threshold information pre-stored in the terminal device. The threshold information includes at least one of following: the first threshold, the second threshold, the third threshold, the fourth threshold, the fifth threshold and the sixth threshold.

[0066] For example, the first resource and the second resource shown in FIG. 3, assuming that the preset condition is that the position of the starting time domain symbol of the first resource is same as the position of the starting time domain symbol of the second resource, and the position of the ending time domain symbol of the first resource is same as the position of the ending time domain symbol of the second resource. Herein the first resource is a resource where the first physical uplink channel, is located, indicated by the network device through the first signaling, and the second resource is a resource used for the grant-free transmission. It can be seen that since a time domain resource occupied by the first resource and a time domain resource occupied by the second resource are same and satisfy the preset condition, the terminal device may carry the data to be transmitted of the first type, that is, data of grant-free transmission, on the first physical uplink channel for transmission (shown in the black bold box).

[0067] For another example, the first resource and the second resource shown in FIG. 4, assuming that the preset condition is that the position of the starting time domain symbol of the first resource is same as the position of the starting time domain symbol of the second resource, or the preset condition is that the position of the starting time domain symbol of the first resource is located after the position of the starting time domain symbol of the second resource, and the position of the ending time domain symbol of the first resource is located before the position of the ending time domain symbol of the second resource. Herein the first resource is a resource where the first physical uplink channel indicated by the network device through the first signaling is located, the second resource is a resource used for the grant-free transmission, and data of the grant-free transmission is repeatedly transmitted by using multiple sub-resources included in the second resource. It can be seen that since the preset condition is satisfied between the first resource and the second resource, the terminal device may carry the data of first type to be transmitted, i.e. data of the grant-free transmission, on the first physical uplink channel for transmission (shown in the black bold box).
