Description

Communication method, device, chip and module equipment

Technical Field

The present application relates to the field of communications, and in particular, to a communication method, device, chip, and module device.

Background

In a communication system, in order to enable an uplink signal transmitted by a terminal device to arrive at a network device synchronously, timing Advance (TA) is proposed. Currently, for the same serving cell, the terminal device may be configured or associated with a timing advance group (timing advance group, TAG) or a TA.

In release 18 (R18) of the communication protocol, multiple transmission reception points (M-TRP) based on multiple downlink control information (multiple downlink control information, M-DCI) are supported and for the same serving cell the terminal device may support TA enhancements, i.e. the terminal device may be configured with multiple TAGs or multiple TAs. At this time, how to determine the uplink transmission timing (UL transmission timing) by the terminal device is a problem to be solved.

Disclosure of Invention

The application provides a communication method, a device, a chip and a module device, which are used for determining uplink transmission timing under the condition that terminal equipment is configured with a plurality of TAGs or a plurality of TAs.

In a first aspect, a communication method is provided, the method comprising: acquiring at least one timing advance or at least one timing advance group of a serving cell; and transmitting a first uplink channel or a first sounding reference signal on the serving cell according to a first timing advance or a first timing advance group, wherein the first timing advance is one of at least one timing advance, and the first timing advance group is one of at least one timing advance group. It can be seen that in case the terminal device supports only one uplink transmission timing, it is achieved that one timing advance or timing advance group is selected from at least one timing advance or at least one timing advance group of the serving cell for transmitting the first uplink channel or the first sounding reference signal on the serving cell. In other words, in the case where the terminal device supports only one uplink transmission timing, the terminal device may determine the uplink transmission timing from at least one timing advance or at least one timing advance group for uplink transmission.

Optionally, the serving cell is a primary cell in a primary cell group of the terminal device; or the service cell is an auxiliary cell in an auxiliary cell group of the terminal equipment; or the service cell is a main cell in the auxiliary cell group of the terminal equipment; or, the serving cell is a main cell of the terminal device.

Optionally, the first timing advance is a minimum or maximum timing advance of the at least one timing advance; or, the first timing advance is a first timing advance or a second timing advance of the at least one timing advance; or, the control resource set pool index associated in advance by the first timing is a first value.

Optionally, the first timing advance group is a timing advance group identifying a minimum or maximum of at least one timing advance group; or, the first timing advance group is a first timing advance group or a second timing advance group in at least one timing advance group; or, the control resource set pool index associated with the first timing advance group is a first value.

Optionally, according to the first timing advance or the first timing advance group, transmitting a first uplink channel or a first sounding reference signal on the serving cell includes: in the case that the uplink transmission time corresponding to the timing advance of the primary cell group of the terminal device is different from the uplink transmission time corresponding to the timing advance of the secondary cell group of the terminal device, transmitting a first uplink channel or a first sounding reference signal on the serving cell according to the first timing advance; or if the uplink transmission time corresponding to the timing advance group of the main cell group of the terminal device is different from the uplink transmission time corresponding to the timing advance group of the auxiliary cell group of the terminal device, sending a first uplink channel or a first sounding reference signal on the serving cell according to the first timing advance group. It can be seen that, in the case that the terminal device supports only one uplink transmission timing, the terminal device may determine that the uplink transmission timing is performed when the uplink transmission time corresponding to the timing advance of the primary cell group of the terminal device is different from the uplink transmission time corresponding to the timing advance of the secondary cell group of the terminal device, or when the uplink transmission time corresponding to the timing advance group of the primary cell group of the terminal device is different from the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device.

Optionally, according to the first timing advance or the first timing advance group, transmitting a first uplink channel or a first sounding reference signal on the serving cell includes: under the condition that the uplink transmission time corresponding to the first timing advance is different from the uplink transmission time corresponding to the timing advance of the auxiliary cell group of the terminal equipment, a first uplink channel or a first sounding reference signal is sent on the serving cell according to the first timing advance; or if the uplink transmission time corresponding to the first timing advance group is different from the uplink transmission time corresponding to the timing advance group of the auxiliary cell group of the terminal equipment, sending a first uplink channel or a first sounding reference signal on the serving cell according to the first timing advance group. It can be seen that, in the case that the terminal device supports only one uplink transmission timing, the terminal device may determine that the uplink transmission timing is to be uplink transmitted when the uplink transmission time corresponding to the first timing advance is different from the uplink transmission time corresponding to the timing advance of the secondary cell group of the terminal device, or when the uplink transmission time corresponding to the first timing advance group is different from the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device.

Optionally, the serving cell is a primary cell in a primary cell group of the terminal device, and the sending, according to the first timing advance or the first timing advance group, the first uplink channel or the first sounding reference signal on the serving cell includes: under the condition that the uplink transmission time corresponding to the first timing advance is the same as the uplink transmission time corresponding to the timing advance of the auxiliary cell group of the terminal equipment, a first uplink channel or a first sounding reference signal is sent on the serving cell according to the timing advance of the main cell group of the terminal equipment; or, if the uplink transmission time corresponding to the first timing advance group is the same as the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device, sending a first uplink channel or a first sounding reference signal on the serving cell according to the timing advance group of the primary cell group of the terminal device. It can be seen that, in the case where the terminal device supports only one uplink transmission timing, the terminal device may determine that the uplink transmission timing is to be uplink transmitted when the uplink transmission time corresponding to the first timing advance is the same as the uplink transmission time corresponding to the timing advance of the secondary cell group of the terminal device, or when the uplink transmission time corresponding to the first timing advance group is the same as the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device.

Optionally, the method further comprises: under the condition that the uplink transmission time corresponding to the first timing advance is the same as the uplink transmission time corresponding to the timing advance of the auxiliary cell group of the terminal equipment, a second uplink channel or a second sounding reference signal of the auxiliary cell group is sent according to the timing advance of the auxiliary cell group of the terminal equipment; or, if the uplink transmission time corresponding to the first timing advance group is the same as the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device, sending a second uplink channel or a second sounding reference signal of the secondary cell group according to the timing advance group of the secondary cell group of the terminal device. It can be seen that, in the case where the terminal device supports only one uplink transmission timing, the terminal device may determine that the uplink transmission timing is to be uplink transmitted when the uplink transmission time corresponding to the first timing advance is the same as the uplink transmission time corresponding to the timing advance of the secondary cell group of the terminal device, or when the uplink transmission time corresponding to the first timing advance group is the same as the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device.

Optionally, the method further comprises: according to the first timing advance or the first timing advance group, a second uplink channel is sent, and the sending time of the first uplink channel is the same as the sending time of the second uplink channel; or, according to the first timing advance or the first timing advance group, transmitting a second sounding reference signal, wherein the transmission time of the first sounding reference signal is the same as that of the second sounding reference signal; wherein the first uplink channel and the second uplink channel are associated with different timing advances or timing advance groups, and the first sounding reference signal and the second sounding reference signal are associated with different timing advances or timing advance groups. It can be seen that in case different uplink data are associated with different timing advances or timing advance groups, since the terminal device supports only one uplink transmission timing, it is necessary to simultaneously transmit different uplink data using the same timing advance or timing advance group. By transmitting different uplink data simultaneously, the data transmission efficiency can be improved.

In a second aspect, a communication method is provided, the method comprising: transmitting a first uplink channel of the plurality of uplink channels on a first time unit; transmitting a second uplink channel of the plurality of uplink channels over a second time unit; the first time unit and the second time unit are time units with the same duration, and the first time unit and the second time unit are overlapped. It can be seen that, by making the duration of the overlapped time units the same, and further making the terminal device able to send the first uplink channel and the second uplink channel on different time units, the problem that the uplink channel cannot be sent because the duration of the later time unit is shortened by the TA command is solved. Meanwhile, by sending different uplink channels in different time units, the resource utilization rate can be improved, and the problem of data loss is avoided.

Optionally, the first time unit and the second time unit overlap due to a timing advance command.

Optionally, the plurality of uplink channels are received by the plurality of sending and receiving points, and the uplink channels are physical uplink control channels or physical uplink shared channels.

Optionally, the uplink channel is a physical uplink control channel, and the spatial information of the plurality of uplink channels is different.

Optionally, the uplink channel is a physical uplink control channel; different uplink channels belong to different channel sets; or, different uplink channels are associated with different sets of power control parameters.

Optionally, the uplink channel is a physical uplink shared channel, and different uplink channels are associated with different sounding reference signal resource sets.

In order to facilitate understanding of the solution provided by the embodiments of the present application, the terms or related techniques related to the solution are first introduced, and will not be repeated in the following description.

1. In a dual connectivity (dual connectivity, DC) or carrier aggregation (carrier aggregation, CA) scenario, one terminal device is configured with two cell groups (cell groups), one of which is a primary cell group (master cell group, MCG) and the other of which is a secondary cell group (secondary cell group, SCG). The primary cell group (master cell group, MCG) refers to one cell group associated with a primary base station (master eNB, meNB) including a primary cell (PCell) and zero or at least one secondary cell (SCell). The secondary cell group (secondary cell group, SCG) refers to one cell group associated with a secondary eNB (SeNB) and includes a primary secondary cell (primary secondary cell, PSCell) and zero or at least one secondary cell.

Wherein, DC may include: evolved universal terrestrial radio access NR dual connectivity (E-UTRA NR dual connectivity, ENDC), NRE-UTRA dual connectivity (NR E-UTRA Dual Connectivity, NEDC), NRDC, etc. The ENDC refers to that the terminal equipment accesses to the NR network through the 4G access network equipment, the 4G access network equipment is used as a main base station, and the 5G access network equipment is used as an auxiliary base station. NEDC refers to 5G access network equipment as a primary base station, and 4G access network equipment as a secondary base station. NRDC refers to two 5G access network devices, one 5G access network device being a primary base station and the other 5G access network device being a secondary base station. For example, in the example shown in fig. 1, the network device 1 may be a primary base station and the network device 2 may be a secondary base station.

It can be appreciated that a primary cell refers to a cell that establishes a radio resource control (radio resource control, RRC) connection with a terminal device, the primary cell being responsible for providing security related parameters and being configured with physical uplink control channel (physical uplink control channel, PUCCH) resources; the primary and secondary cells refer to secondary cells in a secondary cell group configured with PUCCH resources.

It should be understood that when a cell provides service for a terminal device, the cell may be referred to as a serving cell. Such as a primary serving cell (i.e., the primary cell is the serving cell), a primary secondary serving cell (i.e., the primary and secondary cells are the serving cells), a secondary serving cell (i.e., the secondary cell is the serving cell), and so on.

In the DC scenario, one cell may be a serving cell of the terminal device, or multiple cells may be serving cells of the terminal device in the primary cell group and the secondary cell group.

2. A control resource set pool index (coresetpoolndex) is used to indicate a control resource set pool or a control resource set group in which 1 or more control resource sets are included. Different control resource set pool indices may be associated with different TRPs of the same cell, or may be associated with different control resource set groups or different control resource set pools. Illustratively, a control resource set pool index of 0 may be associated with a first TRP of a cell, a control resource set pool index of 1 may be associated with a second TRP of the cell, and vice versa.

3. The set of power control parameters includes power control parameters for determining transmit power of a PUCCH or physical uplink data channel (physical uplink shared channel PUSCH) or a sounding reference signal (Sounding reference signal, SRS).

4. One set of sounding reference signal (sounding reference signal, SRS) resources may include one or more SRS resources, and one SRS resource may include at least one of: time domain resources (including period of periodic resources and slot level offset within the period, slot level offset of non-periodic resources relative to the slot where the activation signaling is located or orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol index within the slot, etc.), frequency domain resources (including bandwidth, frequency hopping configuration or frequency domain comb configuration), power control parameters, and spatial relationship parameters.

5. The TA is generally used for uplink transmission of the terminal device. In order to enable uplink data sent by the terminal equipment to reach the network equipment at a desired time, the transmission delay caused by the distance is estimated, and the uplink data/channel is sent out in advance by corresponding time. For carrier aggregation or dual connectivity configuration, different carriers supported by the terminal device (e.g. comprising one primary carrier and the rest of secondary carriers) are allowed to have different TA values, introducing the concept of timing advance groups (Timing Advance Group, TAG). One timing advance group (timing advance group, TAG) may include one or more serving cells, with the same TA. In general, one MCG or SCG can be configured to associate up to 4 TAGs. In addition, the same carrier may also be configured with different TAs. It should be appreciated that in the present application, a TA may be referred to as an upstream TA and a TAG may be referred to as an upstream TAG group.

6. The time units may be time slots, minislots, symbols, etc., and are not limited herein.

In R18, M-TRP of M-DCI is supported and for the same serving cell the terminal device may support TA enhancements, i.e. the terminal device may be configured with multiple TAGs or multiple TAs. However, in the case that the terminal device supports one uplink transmission timing, how the terminal device determines the uplink transmission timing is a problem to be solved. In order to solve the problem, refer to fig. 2, fig. 2 is a schematic flow chart of a communication method according to an embodiment of the present application. As shown in fig. 2, the communication method includes the following steps 201 to 202. The method execution body shown in fig. 2 may be a terminal device. Alternatively, the method execution body shown in fig. 2 may be a chip in the terminal device. Fig. 2 illustrates an example of a method performed by a terminal device. It should be understood that the terminal device in fig. 2 supports one uplink transmission timing, i.e. the terminal device supports only one TA corresponding to one TA or one TAG for one time.

201. The terminal device obtains at least one TA or at least one TAG of the serving cell.

Wherein the number of the service cells in the present application may be one or more, i.e. the terminal device may be configured with at least one service cell. In the DC or CA scenario, the at least one serving cell may include only cells in the primary cell group, may include only cells in the secondary cell group, may include both cells in the primary cell group and cells in the secondary cell group, and the present application is not limited. One serving cell may be configured with at least one TA or at least one TAG.

For example, if the serving cell includes serving cell 1 and serving cell 2, the TA of serving cell 1 includes TA1 and TA2, and the TA of serving cell 2 includes TA3 and TA4, at least one TA of the serving cell acquired by the terminal device includes TA1, TA2, TA3 and TA4.

The TAG acquiring a serving cell may understand that the TAG to which the serving cell belongs is acquired for one serving cell, for example, if the serving cell 1 belongs to TAG1 and also belongs to TAG2, at least one TAG of the serving cell 1 acquired by the terminal device includes TAG1 and TAG2.

Illustratively, if the serving cell in the present application includes the serving cell 1 and the serving cell 2, the TAG to which the serving cell 1 belongs includes the TAG1 and the TAG2, and the TAG to which the serving cell 2 belongs includes the TAG3 and the TAG4, at least one TAG of the serving cells acquired by the terminal device includes the TAG1, the TAG2, the TAG3 and the TAG4.

In one possible implementation, in a DC or CA scenario, the serving cell may include one or more of the following: a primary cell in a primary cell group of the terminal device (i.e., the serving cell is the primary serving cell in the foregoing), a secondary cell in a secondary cell group of the terminal device (i.e., the serving cell is the secondary serving cell in the foregoing), a primary secondary cell in a secondary cell group of the terminal device (i.e., the serving cell is the primary secondary serving cell in the foregoing), and a secondary cell in a primary cell group of the terminal device.

In another possible implementation, the serving cell is a primary cell of the terminal device. It should be understood that when the terminal device is configured with a serving cell, the serving cell may be referred to as a primary cell of the terminal device; when the terminal device is configured with a plurality of serving cells, one of the plurality of serving cells may be referred to as a primary cell of the terminal device, and the other of the plurality of serving cells may be referred to as a secondary cell of the terminal device.

In another possible implementation, the serving cell is a secondary cell of the terminal device. It should be understood that when the terminal device is configured with a serving cell, the serving cell may be referred to as a primary cell of the terminal device; when the terminal device is configured with a plurality of serving cells, one of the plurality of serving cells may be referred to as a primary cell of the terminal device, and the other of the plurality of serving cells may be referred to as a secondary cell of the terminal device.

In another possible implementation, the serving cells are a primary cell and a secondary cell of the terminal device. It should be understood that when the terminal device is configured with a serving cell, the serving cell may be referred to as a primary cell of the terminal device; when the terminal device is configured with a plurality of serving cells, one of the plurality of serving cells may be referred to as a primary cell of the terminal device, and the other of the plurality of serving cells may be referred to as a secondary cell of the terminal device.

It will be appreciated from the above description that the application scenario of the present application is not limited to DC or CA scenarios, but may also be applied in other scenarios.

Optionally, step 201 may include: the terminal device receives at least one TA or at least one TAG of the serving cell from the network device, and the network device sends the at least one TA or the at least one TAG of the serving cell to the terminal device accordingly. The at least one TA or the at least one TAG of the serving cell may be carried in, for example, a message 2 of four-step random access (Msg 2) or a message B of two-step random access (MsgB) or a medium access control (media access control, MAC) Control Element (CE), which are not limited herein.

202. And the terminal equipment transmits a first uplink channel or a first sounding reference signal on the serving cell according to a first TA or a first TAG, wherein the first TA is one of the at least one TA, and the first TAG is one of the at least one TAG.

The terminal device sends a first uplink channel or a first sounding reference signal on the serving cell according to the first TAG, which can be understood as: and the terminal equipment sends a first uplink channel or a first sounding reference signal on the serving cell according to the TA corresponding to the first TAG.

In the first case (denoted as case one), the first TA may be the smallest or largest TA of the at least one TA. At this time, the terminal device may determine a minimum or maximum TA (i.e., a first TA) from among the at least one TA, and transmit a first uplink channel or a first sounding reference signal on the serving cell according to the minimum or maximum TA. Optionally, when the number of serving cells is multiple, the first TA is the smallest or largest TA among the at least one TA, which can be understood as: the first TA is the smallest or largest TA of the first cells in the at least one TA. In one possible implementation manner, the first cell is a primary cell in a primary cell group of the terminal device, or a secondary cell in a secondary cell group of the terminal device, or a primary and secondary cell in a secondary cell group of the terminal device, or a secondary cell in a primary cell group of the terminal device. In another possible embodiment, the first cell is a primary cell of the terminal device.

In the second case (denoted as case two), the first TA is either the first TA or the second TA of the at least one TA. At this time, the terminal device may determine a first TA or a second TA (i.e., a first TA) from at least one TA, and send a first uplink channel or a first sounding reference signal on the serving cell according to the first TA or the second TA. Wherein the first TA is a TA which is arranged in the first TA from front to back or from back to front in at least one TA, and the second TA is a TA which is arranged in the second TA from front to back or from back to front in at least one TA. In one possible embodiment, the first TA is the smallest TA of the at least one TA and the second TA is the largest TA of the at least one TA; or, the first TA is the largest TA of the at least one TA, and the second TA is the smallest TA of the at least one TA. In another possible implementation, the first TA-associated control resource set pool index is different from the second TA-associated control resource set pool index, e.g., the first TA-associated control resource set pool index is 0, the second TA-associated control resource set pool index is 1, and vice versa. Optionally, when the number of serving cells is multiple, the first TA is a first TA or a second TA in the at least one TA, which can be understood as: the first TA is a first TA or a second TA of the first cell in the at least one TA. At this time, in one possible implementation, the first TA is the smallest TA of the first cell, and the second TA is the largest TA of the first cell; or, the first TA is the largest TA of the first cell, and the second TA is the TA of the first cell. In another possible implementation, the first TA-associated control resource set pool index and the second TA-associated control resource set pool index are different, and the first TA-associated control resource set pool index and the second TA-associated control resource set pool index are the control resource set pool index of the first cell.

In a third case (denoted as case three), the first TA-associated control resource set pool index is a first value. Wherein, in the present application, the first value may be 0 or 1. At this time, the terminal device may determine the first numerical control resource set pool index first, then determine the TA (i.e., the first TA) associated with the first numerical control resource set pool index according to the association relationship between the TA and the control resource set pool index, and send the first uplink channel or the first sounding reference signal on the serving cell according to the TA. As can be seen from the above, the control resource set pool index may be associated with a TRP, if the control resource set pool index of the first value is associated with the first TRP of the serving cell. At this time, the sending of the first uplink channel or the first sounding reference signal on the serving cell according to the first TA may be understood as: and transmitting a first uplink channel or a first sounding reference signal to the first TRP on the serving cell according to the first TA. Optionally, when the number of the serving cells is multiple, the control resource set pool index associated with the first TA is the control resource set pool index of the first cell. Optionally, when the number of the serving cells is multiple, the first TA is a TA associated with the control resource set pool index of the first cell and the control resource set pool index of the first value. For example, if the serving cell includes serving cell 1 and serving cell 2, the TA of serving cell 1 includes TA1 and TA2, the TA of serving cell 2 includes TA3 and TA4, and the at least one TA of the acquired serving cells includes TA1, TA2, TA3 and TA4. If the first TA is TA3, the terminal device sends a first uplink channel or a first sounding reference signal on the serving cell 1 and the serving cell 2 according to TA 3.

In case 1 (denoted as case 1), the first TAG is the TAG identifying the smallest or largest of the at least one TAG. At this time, the terminal device may determine a TAG (i.e., a first TAG) that identifies the minimum or maximum among the at least one TAG, and transmit a first uplink channel or a first sounding reference signal on the serving cell according to a TA corresponding to the minimum or maximum TAG. Alternatively, when the number of serving cells is plural, the first TAG is a TAG identifying the smallest or largest of at least one TAG, which can be understood as: the first TAG is the TAG of at least one TAG with the smallest or largest identity of the first cell.

In case 2 (denoted as case 2), the first TAG is the first TAG or the second TAG of the at least one TAG. At this time, the terminal device may determine a first TAG or a second TAG (i.e., a first TAG) from the at least one TAG, and transmit a first uplink channel or a first sounding reference signal on the serving cell according to a TA corresponding to the first TAG or the second TAG. Wherein the first TAG is a TAG which is arranged in the first TAG from front to back or from back to front in at least one TAG, and the second TAG is a TAG which is arranged in the second TAG from front to back or from back to front in at least one TAG. In one possible embodiment, the first TAG is the TAG that identifies the smallest of the at least one TAGs and the second TAG is the TAG that identifies the largest of the at least one TAGs; alternatively, the first TAG is the TAG that identifies the largest of the at least one TAG and the second TAG is the TAG that identifies the smallest of the at least one TAG. In another possible embodiment, the control resource set pool index associated with the first TAG and the control resource set pool index associated with the second TAG are different. If the control resource set pool index associated with the first TAG is 0, the control resource set pool index associated with the second TAG is 1, and vice versa. Alternatively, when the number of serving cells is plural, the first TAG is the first TAG or the second TAG in the at least one TAG, which can be understood as: the first TAG is a first TAG or a second TAG of a first cell of the at least one TAG. In a possible implementation manner, the first TAG is the TAG with the smallest identifier of the first cell, and the second TAG is the TAG with the largest identifier of the first cell; or, the first TAG is the TAG with the largest identifier of the first cell, and the second TAG is the TAG with the smallest identifier of the first cell. In another possible embodiment, the control resource set pool index associated with the first TAG and the control resource set pool index associated with the second TAG are different, and the control resource set pool index associated with the first TAG and the second TAG is the control resource set pool index of the first cell.

In case 3 (denoted as case 3), the control resource set pool index associated with the first TAG is a first value. At this time, the terminal device may determine the control resource set pool index of the first value first, then determine the TAG (i.e., the first TAG) associated with the control resource set pool index of the first value according to the association relationship between the TAG and the control resource set pool index, and send the first uplink channel or the first sounding reference signal on the serving cell according to the TA corresponding to the TAG. As can be seen from the above, the control resource set pool index may be associated with a TRP, if the control resource set pool index of the first value is associated with the first TRP of the serving cell. At this time, the sending of the first uplink channel or the first sounding reference signal on the serving cell according to the TA corresponding to the first TAG may be understood as: and transmitting a first uplink channel or a first sounding reference signal to the first TRP on the serving cell according to the TA corresponding to the first TAG. Optionally, when the number of the serving cells is multiple, the control resource set pool index associated with the first TAG is the control resource set pool index of the first cell. Optionally, when the number of the serving cells is multiple, the first TAG is a TAG associated with a control resource set pool index of the first cell, where the control resource set pool index is a first value. Illustratively, if the serving cell includes serving cell 1 and serving cell 2, the TAG to which serving cell 1 belongs includes TAG1 and TAG2, and the TAG to which serving cell 2 belongs includes TAG3 and TAG4, then the at least one TAG of the acquired serving cells includes TAG1, TAG2, TAG3 and TAG4. If the first TAG is TAG3, the terminal equipment sends a first uplink channel or a first sounding reference signal on the serving cell 1 and the serving cell 2 according to the TA corresponding to the TAG 3.

The first uplink channel may be PUCCH or PUSCH.

Alternatively, step 202 may be understood as any of the following ways.

Mode 1, when uplink transmission time corresponding to a TA of a primary cell group of a terminal device is different from uplink transmission time corresponding to a TA of a secondary cell group of the terminal device, the terminal device sends a first uplink channel or a first sounding reference signal on a serving cell according to a first TA; or under the condition that the uplink transmission time corresponding to the TAG of the main cell group of the terminal equipment is different from the uplink transmission time corresponding to the TAG of the auxiliary cell group of the terminal equipment, the terminal equipment sends a first uplink channel or a first sounding reference signal on the serving cell according to the first TAG. In the present application, the uplink transmission time is understood as the uplink transmission time, and the uplink transmission time corresponding to a TA is understood as the time for uplink transmission determined according to the TA. In the present application, the uplink transmission time may be understood as an uplink transmission timing, and the uplink transmission time corresponding to one TA may be understood as an uplink transmission timing determined according to the TA.

In the present application, the uplink transmission time corresponding to the TA of the primary cell group of the terminal device may be understood as: uplink transmission time corresponding to TA of partial or all cells in the main cell group of the terminal equipment. Illustratively, the uplink transmission time corresponding to the TA of the primary cell group of the terminal device may be understood as: and uplink transmission time corresponding to one TA (e.g. any one or preset one) in the main cell group of the terminal equipment. Similarly, the uplink transmission time corresponding to the TAG of the primary cell group of the terminal device can be understood as: and uplink transmission time corresponding to TAGs of part or all cells in the main cell group of the terminal equipment. The uplink transmission time corresponding to the TAG of the primary cell group of the terminal device can be illustratively understood as: and (3) uplink transmission time corresponding to one TAG (e.g. any one or preset one) in the main cell group of the terminal equipment. The uplink transmission time corresponding to the TA of the secondary cell group of the terminal device can be understood as: uplink transmission time corresponding to TA of partial or all cells in the secondary cell group of the terminal equipment. The uplink transmission time corresponding to the TAG of the secondary cell group of the terminal device can be understood as: and uplink transmission time corresponding to TAGs of part or all cells in the secondary cell group of the terminal equipment.

Mode 2, when the uplink transmission time corresponding to the first TA is different from the uplink transmission time corresponding to the TA of the secondary cell group of the terminal device, the terminal device sends a first uplink channel or a first sounding reference signal on the serving cell according to the first TA; or, if the uplink transmission time corresponding to the first TAG is different from the uplink transmission time corresponding to the TAG of the secondary cell group of the terminal device, the terminal device sends the first uplink channel or the first sounding reference signal on the serving cell according to the first TAG.

In modes 1 and 2, "transmitting the first uplink channel or the first sounding reference signal on the serving cell according to the first TA" can be understood as: and transmitting a first uplink channel or a first sounding reference signal on the serving cell by adopting the first TA. "transmitting the first uplink channel or the first sounding reference signal on the serving cell according to the first TAG" can be understood as: and transmitting a first uplink channel or a first sounding reference signal on the serving cell by adopting the TA corresponding to the first TAG.

Mode 3, when the uplink transmission time corresponding to the first TA is the same as the uplink transmission time corresponding to the TA of the secondary cell group of the terminal device, the terminal device sends a first uplink channel or a first sounding reference signal on the serving cell according to the TA of the primary cell group of the terminal device; or under the condition that the uplink transmission time corresponding to the first TAG is the same as the uplink transmission time corresponding to the TAG of the auxiliary cell group of the terminal equipment, the terminal equipment sends a first uplink channel or a first sounding reference signal on the serving cell according to the TAG of the main cell group of the terminal equipment.

In mode 3, the first uplink channel or the first sounding reference signal is sent on the serving cell according to the TA of the primary cell group of the terminal device, which can be understood as: the terminal device sends a first uplink channel or a first sounding reference signal on the serving cell according to (e.g., using) one TA (e.g., any one TA or a preset TA) of the primary cell group of the terminal device. Similarly, the terminal device sends the first uplink channel or the first sounding reference signal on the serving cell according to the TAG of the main cell group of the terminal device, which can be understood as: the terminal device sends a first uplink channel or a first sounding reference signal on the serving cell according to (e.g. using) a timing advance corresponding to one TAG (e.g. any one TAG or a preset TAG) of the primary cell group of the terminal device.

In modes 1 to 3, the first TA of the first case, the second case, or the third case is specifically adopted, or the first TAG of the first case 1, the second case, or the third case is specifically adopted, which may be determined by the terminal device, configured by the network device, or may be pre-configured by a protocol specification or other modes, and the present application is not limited.

It can be seen that in any of the above modes 1 to 3, in the case where the terminal device supports only one uplink transmission timing, the terminal device can determine the uplink transmission timing at which the uplink transmission is performed.

In one possible embodiment, for any one of modes 1 to 3, the method further includes: under the condition that the uplink transmission time corresponding to the first TA is the same as the uplink transmission time corresponding to the TA of the auxiliary cell group of the terminal equipment, the terminal equipment sends a second uplink channel or a second sounding reference signal of the auxiliary cell group according to the TA of the auxiliary cell group of the terminal equipment; or, under the condition that the uplink transmission time corresponding to the first TAG is the same as the uplink transmission time corresponding to the TAG of the auxiliary cell group of the terminal equipment, the terminal equipment sends a second uplink channel or a second sounding reference signal of the auxiliary cell group according to the TAG of the auxiliary cell group of the terminal equipment.

The second uplink channel may be PUCCH or PUSCH.

Optionally, the terminal device sends the second uplink channel or the second sounding reference signal of the secondary cell group according to the timing advance group of the secondary cell group of the terminal device, which can be understood as: and the terminal equipment sends a second uplink channel or a second sounding reference signal of the secondary cell group according to (e.g. adopting) a timing advance corresponding to one timing advance group (e.g. any one TAG or a preset TAG) of the secondary cell group of the terminal equipment.

It can be seen that, in the case where the terminal device supports only one uplink transmission timing, the terminal device may determine that the uplink transmission timing is to be uplink transmitted when the uplink transmission time corresponding to the first timing advance is the same as the uplink transmission time corresponding to the timing advance of the secondary cell group of the terminal device, or when the uplink transmission time corresponding to the first timing advance group is the same as the uplink transmission time corresponding to the timing advance group of the secondary cell group of the terminal device.

In another possible embodiment, for any one of modes 1 to 3, the method further includes: the terminal equipment sends a second uplink channel according to the first TA or the first TAG, and the sending time of the first uplink channel is the same as that of the second uplink channel; or the terminal equipment sends a second sounding reference signal according to the first TA or the first TAG, and the sending time of the first sounding reference signal is the same as the sending time of the second sounding reference signal; wherein the first uplink channel and the second uplink channel are associated with different TAs or TAGs, and the first sounding reference signal and the second sounding reference signal are associated with different TAs or TAGs.

Optionally, the terminal device sends the second uplink channel according to the first TAG, which can be understood as: and the terminal equipment sends the second uplink channel according to (for example, by adopting) the TA corresponding to the first TAG. Similarly, the terminal device sends the second sounding reference signal according to the first TAG, which can be understood as: the terminal device sends a second sounding reference signal according to (e.g., using) the TA corresponding to the first TAG.

It can be seen that in case different uplink data are associated with different timing advances or timing advance groups, since the terminal device supports only one uplink transmission timing, it is necessary to simultaneously transmit different uplink data using the same timing advance or timing advance group. By transmitting different uplink data simultaneously, the data transmission efficiency can be improved.

Currently, there may be a problem that two adjacent slots overlap due to a TA command (TA command). In this case, the duration of the latter time slot may be shortened so that the uplink channel is not transmitted on the latter time slot. However, not transmitting the uplink channel on the latter slot may have problems of reduced resource utilization and data loss. In order to solve the problem, reference may be made to fig. 3, and fig. 3 is a schematic flow chart of another communication method according to an embodiment of the present application. As shown in fig. 3, the communication method includes the following steps 301 and 302. The method execution body shown in fig. 3 may be a terminal device. Alternatively, the method execution body shown in fig. 3 may be a chip in the terminal device. Fig. 3 illustrates an example of a method performed by a terminal device. It should be understood that the terminal device in fig. 3 supports multiple uplink transmission timings, that is, the terminal device supports uplink transmission with multiple TAs or TAs corresponding to multiple TAGs at the same time. Meanwhile, the terminal device in fig. 3 also supports multiple PUCCHs, or the terminal device also supports multiple PUSCH simultaneous transmissions, or the terminal device also supports at least one PUCCH and at least one PUSCH simultaneous transmission.

301. The terminal device transmits a first uplink channel of the plurality of uplink channels on a first time unit.

Correspondingly, the network device receives the first uplink channel.

302. The terminal device transmits a second uplink channel of the plurality of uplink channels on a second time unit. The first time unit and the second time unit are time units with the same duration, and the first time unit and the second time unit are overlapped.

Correspondingly, the network device receives the second uplink channel.

The plurality of uplink channels may be a plurality of PUCCHs, or the plurality of uplink channels may be a plurality of PUSCHs, or the plurality of uplink channels may be at least one PUCCH and at least one PUSCH, which is not limited herein.

In a possible implementation manner, the first uplink channel may be PUCCH or PUSCH.

In a possible implementation manner, the second uplink channel may be PUCCH or PUSCH. It should be appreciated that the first uplink channel and the second uplink channel may be the same type or different types of channels. The first and second uplink channels may also carry the same or different data.

Optionally, the plurality of uplink channels are received by a plurality of TRPs, e.g. the plurality of PUCCHs are received by a plurality of TRPs, or the plurality of PUSCHs are received by a plurality of TRPs, or the at least one PUCCH and the at least one PUSCH are received by a plurality of TRPs.

Optionally, the plurality of uplink channels are a plurality of PUCCHs. In one case, the spatial information of the plurality of uplink channels is different, that is, the spatial information of the plurality of PUCCHs is different. In another case, different uplink channels belong to different channel sets, which may include at least one PUCCH; or, different uplink channels are associated with different sets of power control parameters.

Optionally, the plurality of uplink channels are a plurality of PUSCHs, and different uplink channels are associated with different sounding reference signal resource sets.

Optionally, the plurality of uplink channels includes at least one PUCCH and at least one PUSCH. At this time, the spatial information of different PUCCHs is different, or different PUCCHs belong to different channel sets, or different PUCCHs are associated with different power control parameter sets. Different PUSCHs are associated with different sets of sounding reference signal resources. The first uplink channel and the second uplink channel may be the same type of channel, for example, PUCCH, where spatial information of the first uplink channel and the second uplink channel is different or belongs to different channel sets or associates different power control parameter sets, and for example, PUSCH, where the first uplink channel and the second uplink channel are associated with different sounding reference signal resource sets. The first uplink channel and the second uplink channel may also be different types of channels, for example, one may be PUCCH and the other may be PUSCH.

Wherein the first time unit and the second time unit overlap, which can be understood as: the first time unit and the second time unit partially or completely overlap. In a possible embodiment, the first time unit and the second time unit overlap due to a TA command. It should be appreciated that the first time unit and the second time unit are adjacent before the terminal device receives the TA command. After the terminal device receives the TA command, the first time unit and the second time unit may overlap due to the TA command.

Optionally, step 301 may include: and the terminal equipment transmits a first uplink channel on the first time unit according to the first TA or the TA corresponding to the first TAG. The first TA may be one of at least one TA of a serving cell of the terminal device, and the first TAG may be one of at least one TAG of the serving cell of the terminal device. For relevant descriptions of the serving cell, the first TA, and the first TAG, reference is made to the above, and no further description is given here.

Optionally, step 302 may include: and the terminal equipment sends a second uplink channel on a second time unit according to the second TA or the TA corresponding to the second TAG.

In fig. 3, the first TA and the second TA may be the same or different, and the first TAG and the second TAG may be the same or different.

There is no necessary precedence relationship between step 301 and step 302. As step 301 may be performed before step 302, or step 301 may be performed after step 302, or step 301 and step 302 may be performed simultaneously.

It can be seen that, by making the duration of the overlapped time units the same, and further making the terminal device able to send the first uplink channel and the second uplink channel on different time units, the problem that the uplink channel cannot be sent because the duration of the later time unit is shortened by the TA command is solved. Meanwhile, by sending different uplink channels in different time units, the resource utilization rate can be improved, and the problem of data loss is avoided.
