In order to better understand the technical solution provided by the embodiments of the present application, first, technical terms related to the embodiments of the present application are described.

(1) Timing advance command (Timing Advance Command, TAC)

The network device sends the TAC to the terminal device to indicate the specific content of the terminal device TA. Illustratively, the TAC may indicate a TA value.

(2) Timing advance group (Timing Advance Group, TAG)

One TAG may be associated with one or more cells. For example, if TAG1 is associated with cell a and cell b, then the TA values associated with TAG1 for cell a and cell b may be the same.

In the current third generation partnership project (3rd Generation Partnership Project,3GPP) 38.331 protocol, a cell is configurable to be associated with a TAG. In the embodiment of the application, one cell may be configured to be associated with one or more TAGs, and illustratively, a first cell may be configured to be associated with a first TAG, and optionally, the first cell may also be configured to be associated with a second TAG.

In the current protocol, each primary cell group (Master Cell group, MCG) or secondary cell group (Secondary Cell group, SCG) may be configurable to associate up to 4 TAGs, each cell in the MCG or SCG may be configurable to associate one TAG, and different cells may be configurable to associate different TAGs.

(3) A control resource set (Control Resource Set, coreset); control resource pool index (Control Resource Set Pool Index, coresetPoolIndex)

Coreset is used to configure information such as frequency domain resources occupied on the physical downlink control channel (Physical Downlink Control Channel, PDCCH) frequency domain and the number of orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbols occupied on the time domain. Coreset can comprise a plurality of physical resource blocks (Physical Resource Block, PRBs) in the frequency domain and 1-3 OFDM symbols in the time domain.

Coreset can be configured by the high-level parameter PDCCH-Config, the high-level parameter ControlResourceSet can configure the value of CorestPoolIndex, which can be 0, 1.

It will be appreciated that the control resource set is associated with the coresetpoinlindex contained in its configuration information. The PDCCH is associated with coresetpoinlindex, which can be considered as the coresetpoinlindex with which the PDCCH is associated with its associated controlresource. In the examples herein, coresetpoolndex has the same meaning as coresetpoolndex.

Alternatively, in the embodiment of the present application, the first coresetpoil index may be a coresetpoil index having a value of 0, and the second coresetpoil index may be a coresetpoil index having a value of 1. Alternatively, the first coresetpoil index may be a coresetpoil index of value 1 and the second coresetpoil index may be a coresetpoil index of value 0.

(4) Transmitting and receiving point (transmission and reception point, TRP)

It is understood that in the embodiment of the present application, TRP may be considered as a network side transmission receiving point associated with coresetpoolndex. For example, the network side transmission and reception point associated with coresetpoolndex having a value of 0 is the first TRP, and the network side transmission and reception point associated with coresetpoolndex having a value of 1 is the second TRP.

It is understood that in the embodiment of the present application, 1 cell may be configured of 1 TRP, or may be configured of a plurality of TRPs. The TRP is a logical concept here, and 1 TRP may be a physical network site such as: the remote radio head (Remote Radio Head, RRH), base station, 1 TRP may also be made up of multiple physical network stations.

The specific definition of TRP is not limited in this application and will not be described in detail.

Referring to fig. 2, a flow chart of a configuration method provided in the embodiment of the present application is shown, and in the corresponding embodiment of fig. 2, the first configuration information is used to configure a TA corresponding to coresetpoolndex. As shown in fig. 2, the configuration method may include, but is not limited to, the following steps:

s201, the network equipment determines first configuration information; the first configuration information is used for configuring a first TA corresponding to the first CorestPoolIndex and/or a second TA corresponding to the second CorestPoolIndex; the first coresetpoinolindex and the second coresetpoinolindex are each associated with a first cell.

The first configuration information may include first configuration information 1 and/or first configuration information 2, where the first configuration information 1 is used to configure a first TA corresponding to the first coresetpoolndex, and the first configuration information 2 is used to configure a second TA corresponding to the second coresetpoolndex.

Wherein the meaning of the first TA corresponding to the first coresetpoolndex is: for a terminal device that is within the coverage of a first cell, the TA value of the uplink transmission may be obtained by the first TA in case the terminal device sends an uplink channel or uplink signal associated with the first coresetpoolndex to the network device. The meaning of the second TA corresponding to the second coresetpoolndex is: for a terminal device that is within the coverage of the first cell, the TA value of the uplink transmission may be obtained by the second TA in case the terminal device sends an uplink channel or uplink signal associated with the second coresetpoolndex to the network device.

It may be appreciated that the uplink channel or uplink signal associated with the first corespolol index may be an uplink channel or uplink signal scheduled or triggered by the PDCCH associated with the first corespolol index, or may be an uplink channel or uplink signal associated with the first corespolol index configured by the network or predefined by the protocol.

It may be appreciated that the uplink channel or uplink signal associated with the second corespolol index may be an uplink channel or uplink signal scheduled or triggered by the PDCCH associated with the second corespolol index, or may be an uplink channel or uplink signal associated with the second corespolol index configured by the network or predefined by the protocol.

In one implementation, the first coresetpoolndex may have an association with a first TRP, where TA of the first TRP is the first TA; the second coresetpoolndex may have an association with a second TRP, the TA of the second TRP being the aforementioned second TA; the first TRP and the second TRP both belong to the first cell. In other words, according to the TA corresponding to a corespoolindex (e.g., the first corespoolindex) and the association relationship between corespoolindex and TRP, the TA of the first TRP associated with the first corespoolindex may be determined, where the TA of the first TRP is the TA corresponding to the first corespoolindex. Alternatively, according to the TA of a certain TRP (e.g., the first TRP) and the association relationship between coresetpool index and TRP, the TA corresponding to the first coresetpool index associated with the first TRP may be determined, where the TA corresponding to the first coresetpool index is the TA of the first TRP.

The first coresetpoil index has an association with the first TRP, the second coresetpoil index has an association with the second TRP, and in other implementations, the first coresetpoil index may have an association with the second TRP, and the second coresetpoil index may have an association with the first TRP.

Wherein the meaning of TA of the first TRP is: for a terminal device in the coverage area of a first cell, a TA value for uplink transmission may be obtained by the TA in case the terminal device sends an uplink channel or uplink signal associated with a first TRP to a network device first TRP. Similarly, the meaning of TA of the second TRP is: for a terminal device in the coverage area of a first cell, a TA value for uplink transmission may be obtained by the TA in case the terminal device transmits an uplink channel or uplink signal associated with a second TRP to a network device second TRP.

S202, the network equipment sends the first configuration information. Correspondingly, the terminal equipment receives the first configuration information.

The network device sends the first configuration information to the terminal device. The network device illustratively broadcasts the first configuration information in a first cell. Accordingly, the terminal device in the coverage area of the first cell may receive the first configuration information. Alternatively, the first cell may be a serving cell of the terminal device.

The first configuration information 1 and the first configuration information 2 may be carried in the same message or may be carried in different messages. In the case where the first configuration information 1 is carried in the message 1 and the first configuration information 2 is carried in the message 2, the order in which the network device sends the message 1 and the message 2 is not limited in the embodiment of the present application. For example, the network device may send message 1 first, or may send message 2 first, or may send both message 1 and message 2. Optionally, the first configuration information may be carried in a media access Control-Control Element (MAC-CE) signaling.

In one implementation, the first cell may be associated with a TAG (e.g., a first TAG), where the TA corresponding to the first TAG is the first TA. At this time, the network device may configure the first TAG associated with the first cell by issuing configuration information. The network device sends, for example, second configuration information, which is used to configure the first TAG associated with the first cell, and the terminal device receives, for example, the second configuration information, which may include identification information (TAG ID) of the first TAG. Wherein the first TAG has an association with the first CoresetPoolIndex. Optionally, the first cell may be further associated with a second TAG, where the TA corresponding to the second TAG is a second TA. At this time, the first cell is associated with two TAGs, and the aforementioned second configuration information may also be used to configure the second TAG associated with the first cell. Wherein the second TAG has an association with the second CoresetPoolIndex. Optionally, the second configuration information may be carried in a radio resource control (Radio Resource Control, RRC). In the embodiment of the application, the association relationship between the TAG and coresetpoolndex may be predefined by a protocol, or may be indicated by a network device. The network device sends the third configuration information to the terminal device, and the terminal device receives the third configuration information. The third configuration information may be used to configure the first TAG to have an association with the first coresetpoolndex and/or the third configuration information may be used to configure the second TAG to have an association with the second coresetpoolndex.

For example, referring to fig. 3, the MAC CE shown in fig. 3 may explicitly indicate an association between TAG and coresetpoolndex. In fig. 3, coresetPool ID field is used to indicate the value of CoresetPool index, and TAG ID field is used to indicate a TAG. If the CoresetPool ID field in fig. 3 has a value of 0, then CoresetPool index having a value of 0 has an association with the TAG indicated by the TAG ID field in fig. 3. In fig. 3, the serving cell identifier may be an identifier of the first cell (such as a PCI of the first cell), and a partial Bandwidth Part (BWP) identifier is used to indicate the allocated Bandwidth. T (T) _i For transmitting an identification of the configuration indication (Transmission Configuration Indicator, TCI) State (State). T (T) _i Has a value of 1 or 0, for indicating that T is present _i An active or inactive state of the TCI state of (c). In fig. 3, oct represents a byte, a character following Oct represents an index of the byte, one byte occupies 8 bits, a trellis represents a bit in fig. 3, and R represents a reserved field.

Optionally, in this embodiment of the present application, the first TAG is a first TAG in the network configuration or the first configuration information or the second configuration information or the third configuration information, and the second TAG is a second TAG in the network configuration or the first configuration information or the second configuration information or the third configuration information.

Optionally, in this embodiment of the present application, the first TAG is a second TAG in the network configuration or the first configuration information or the second configuration information or the third configuration information, and the second TAG is a first TAG in the network configuration or the first configuration information or the second configuration information or the third configuration information.

Alternatively, in the embodiment of the present application, the first TAG is the TAG with the smallest ID, and the second TAG is the TAG with the largest ID. Illustratively, the first TAG is the smallest ID TAG of the TAGs associated with the first cell; the second TAG is the TAG with the largest ID among TAGs associated with the first cell.

Alternatively, in embodiments of the present application, the first TAG is the TAG with the largest ID and the second TAG is the TAG with the smallest ID in the practice of the present application. Illustratively, the first TAG is the largest ID TAG of the TAGs associated with the first cell; the second TAG is the smallest ID TAG among TAGs associated with the first cell.

In one implementation, the aforementioned second TA may be determined by the first TA. In particular, the second TA may be determined by the first TA, and an offset (offset-1) of the second TA relative to the first TA. Illustratively, second TA value = first TA value + (offset-1). It should be noted that, the second TA is determined by the first TA, and the second TA is determined by the first TA and the offset (offset-1) of the second TA relative to the first TA are used for example, and in other implementations, the first TA may be determined by the second TA, and the first TA may be determined by the second TA and the offset (offset 2) of the first TA relative to the second TA. Illustratively, first TA value = second TA value+ (offset-2).

Alternatively, the aforementioned offsets (e.g., offset1, offset 2) may be predefined by the protocol, or may be indicated by the network device. The network device sends an offset to the terminal device, and the terminal device receives the offset, and further determines a second TA according to the offset and the first TA. Optionally, the offset may be carried in RRC, MAC CE or downlink control information (Downlink Control Information, DCI). The offset may or may not be included in the first configuration information. The offset may be included in the same message as the first configuration information.

The corresponding embodiment of fig. 2 may include the following 2 cases:

case 1: the first cell is associated with two TAGs (i.e., a first TAG having an association with a first coresetpooolindex, a second TAG having an association with a second coresetpooolindex). The TA corresponding to the first coresetpoolndex is the same as the TA corresponding to the first TAG and the TA corresponding to the second coresetpoolndex is the same as the TA corresponding to the second TAG. Therefore, the TA corresponding to coresetpoolndex can be configured by configuring the TA corresponding to TAG. For specific configuration of the TA corresponding to the TAG, see the example diagrams of fig. 4 and fig. 5, where fig. 4 and fig. 5 take the example of carrying the first configuration information through the MAC CE.

Taking the first cell to associate two TAGs as an example. In fig. 4, a network device may transmit two MAC CEs, both of which contain a TAG ID field and a TAC field. One of the MAC CEs is used for indicating a TA corresponding to one of the TAGs (e.g., the first TAG) associated with the first cell, i.e., the TAG ID field in the MAC CE is used for indicating one of the TAGs associated with the first cell, and the TAC field in the MAC CE is used for indicating the value of the TA corresponding to the TAG indicated by the TAG ID field. The other MAC CE is used to indicate the TA corresponding to the other TAG (e.g. the second TAG) associated with the first cell, i.e. the TAG ID field in the MAC CE is used to indicate the other TAG associated with the first cell, and the TAC field in the MAC CE is used to indicate the value of the TA corresponding to the TAG indicated by the TAG ID field. It should be noted that the MAC CE may also carry other contents, and only the TAG ID field and the TAC field are shown in fig. 4 and 5. In fig. 5, a network device may transmit one MAC CE containing 2 TAG ID fields and 2 TAC fields, which is different from the structure of the MAC CE in fig. 4. The content of Oct1 in the MAC CE shown in fig. 5 may be understood as the same content as one of the MAC CEs in fig. 4, and the content of Oct2 may be understood as the same content as the other MAC CE in fig. 4.

Although NR system Release 16 (Release 16, rel-16) supports multi-TRP (M-TRP) transmission based on multi-DCI (multi DCI), the multi-TRP belongs to the same cell. Since one cell configuration is associated with one TAG and one TAG configures one TA in the current protocol, the current protocol does not support separately configuring the TAs for different TRPs, which are associated with corespoolindices, and thus the current protocol does not support separately configuring corresponding TAs for different corespoolindices. However, in case 1 of the embodiment of the present application, a plurality of TAGs may be configured for the first cell, one TAG for each TA, so that the TAs may be configured for different coresetpoolndexs belonging to the first cell, i.e. each coresetpoolndex is each TA (per CoresetPoolIndex per TA).

Case 2: the first cell is associated with a TAG (e.g., a first TAG) having an association with a first coresetpoolndex; the TA corresponding to the first corespoolindex is the same as the TA corresponding to the first TAG (e.g., the first TA), so that the configuration of the TA corresponding to the first corespoolindex can be achieved by configuring the TA corresponding to the first TAG. For the second TA of the second coresetpoolndex, it may be determined by the first TA (i.e., the TA corresponding to the TAG associated with the first cell) or may be indicated by the TAC. For case 2, the aforementioned second configuration information may be used to configure a first TAG associated with the first cell, and the aforementioned first configuration information may include, but is not limited to, at least one of: identification information of the first TAG (first TAG ID), TAC for indicating the first TA, TAC for indicating the second TA. How to configure the TA corresponding to coresetpoolndex can be seen in the example diagram of fig. 6, fig. 6 taking the first configuration information carried by the MAC CE as an example. In fig. 6, a network device may transmit one MAC CE containing 1 TAG ID field, 2 TAC fields, and reserved field R. Each of Oct1 and Oct2 includes a TAC field, where the TA value indicated by the TAC field in Oct1 is a TA value corresponding to the TAG indicated by the TAG ID field in the MAC CE, where the TAG ID field may be used to indicate the TAG associated with the first cell. Note that the TA value indicated by Oct1 in fig. 6 is applicable to corespoolindices (e.g., the first corespoolindex) associated with the TAG (associated with the first cell), and the TA value indicated by Oct2 is applicable to other corespoolindices (e.g., corespoolindices other than the first corespoolindex, i.e., the second corespoolindex). In this way, even if the first cell is associated with one TAG, the TA can be configured separately for the different coresetpoolndexs associated with the first cell, i.e. each coresetpoolndex per TA (per CoresetPoolIndex per TA) can be implemented.

For case 2, in one implementation, the TAG associated with the first cell may be associated with the first coresetpoolndex or the second coresetpoolndex by default. In another implementation, the network device may configure to which coresetpoolndex the TAG (associated with the first cell) is associated.

S203, the terminal equipment obtains the first TA and/or the second TA according to the first configuration information.

After receiving the first configuration information, if the first configuration information is used for configuring a first TA corresponding to the first coresetpoolndex, the terminal device may obtain the first TA according to the first configuration information. If the first configuration information is used for configuring a second TA corresponding to the second coresetpoolndex, the terminal device may obtain the second TA according to the first configuration information. If the first configuration information is used for configuring a first TA corresponding to the first coresetpoolndex and a second TA corresponding to the second coresetpoolndex, the terminal device may obtain the first TA and the second TA according to the first configuration information.

By implementing the embodiment of the application, the TA configuration can be carried out for each CoresetPoolIndex, namely, each TRP, so that the time synchronization of the network equipment side is ensured. Specifically, for case 1, multiple TAGs may be configured for a first cell, one TAG for each TA, so that TAs may be configured for different coresetpoolndexs associated with the first cell, respectively. For case 2, even though the first cell is associated with one TAG, TAs may be configured separately for different coresetpooolindices associated with the first cell. Per CoresetPoolIndex per TA can be implemented in both case 1 and case 2.

Referring to fig. 7, a flowchart of another configuration method provided in the embodiment of the present application is shown, and fig. 7 corresponds to a first configuration information in the embodiment of the present application, which is used to configure a TA of a TRP. As shown in fig. 7, the configuration method may include, but is not limited to, the following steps:

s701, the network equipment determines first configuration information; the first configuration information is used for configuring a first TA of a first TRP and/or a second TA of a second TRP, and the first TRP and the second TRP belong to a first cell.

The first configuration information may include first configuration information 1 and/or first configuration information 2, where the first configuration information 1 is used to configure a first TA of the first TRP, and the first configuration information 2 is used to configure a second TA of the second TRP.

The meaning of the first TA of the first TRP is: for a terminal device in the coverage area of a first cell, in the case that the terminal device sends an uplink channel or an uplink signal associated with a first TRP to a first TRP of a network device, a TA value of an uplink transmission may be obtained by the first TA. Similarly, the meaning of the second TA of the second TRP is: for a terminal device in the coverage area of a first cell, in the case that the terminal device sends an uplink channel or an uplink signal associated with a second TRP to a network device, a TA value of uplink transmission can be obtained by the second TA.

In one implementation, the first configuration information may be specifically used to configure a first TA corresponding to the first coresetpoolndex and/or a second TA corresponding to the second coresetpoolndex. For example, the first configuration information 1 is specifically configured to configure a first TA corresponding to a first corespoolindex, and the first configuration information 2 is configured to configure a second TA corresponding to a second corespoolindex. Wherein the first coresetPoolIndex has an association with the first TRP and the second coresetPoolIndex has an association with the second TRP. Illustratively, a coresetpoil index of 0 has an association with a first TRP and a coresetpoil index of 1 has an association with a second TRP. In other words, the TA configuring the TRP can be specifically realized by the following embodiments: the TA corresponding to corespoolindex is configured to implement the configuration of the TA of the TRP having an association with the corespoolindex, and a specific description of how the TA corresponding to corespoolindex is configured may be found in the corresponding embodiment of fig. 2. The first configuration information is specifically configured to configure a first TA corresponding to a corespoolindex with a value of 0, and/or specifically configured to configure a second TA corresponding to a corespoolindex with a value of 1.

S702, the network equipment sends the first configuration information. Correspondingly, the terminal equipment receives the first configuration information, and the terminal equipment is in the coverage area of the first cell.

The network device sends the first configuration information to the terminal device. For example, the network device may broadcast the first configuration information in the first cell. Accordingly, the terminal device in the coverage area of the first cell may receive the first configuration information. Alternatively, the first cell may be a serving cell of the terminal device.

In one implementation, the first cell may be associated with a TAG (e.g., a first TAG), where the TA corresponding to the first TAG is the first TA. At this time, the network device may configure the first TAG associated with the first cell by issuing configuration information. The network device sends, for example, second configuration information, which is used to configure the first TAG associated with the first cell, and the terminal device receives, for example, the second configuration information, which may include identification information (TAG ID) of the first TAG. Wherein the first TAG has an association relationship with the first TRP. Optionally, the first cell may be further associated with a second TAG, where the TA corresponding to the second TAG is a second TA. At this time, the first cell is associated with two TAGs, and the aforementioned second configuration information may also be used to configure the second TAG associated with the first cell. Wherein the second TAG has an association with the second TRP. Optionally, the second configuration information may be carried in a radio resource control (Radio Resource Control, RRC).

In the embodiment of the present application, the association relationship between the TAG and the TRP may be predefined by the protocol, or may be indicated by the network device. The network device sends the third configuration information to the terminal device, and the terminal device receives the third configuration information. The third configuration information may be used to configure the first TAG to have an association with the first TRP, and/or the third configuration information may be used to configure the second TAG to have an association with the second TRP. For example, referring to fig. 3, the MAC CE shown in fig. 3 may explicitly indicate an association between the TAG and the coresetpooolindex, and thus, the MAC CE may implicitly indicate an association between the TAG and the TRP because the coresetpooolindex has an association with the TRP. If the CoresetPool ID field in fig. 3 has a value of 0, then CoresetPool index having a value of 0 has an association with the TAG indicated by the TAG ID field in fig. 3. If the coresetpoolndex having the value of 0 has an association with the first TRP, it indicates that the TAG indicated by the TAG ID field in fig. 3 has an association with the first TRP.

Alternatively, the aforementioned offsets (e.g., offset1, offset 2) may be predefined by the protocol, or may be indicated by the network device. The network device sends an offset, and the terminal device receives the offset, and further determines a second TA according to the offset and the first TA. Optionally, the offset may be carried in RRC, MAC CE or downlink control information (Downlink Control Information, DCI). The offset may or may not be included in the first configuration information. The offset may be included in the same message as the first configuration information.

The corresponding embodiment of fig. 7 may include the following 2 cases:

case 3: the first cell is associated with two TAGs (i.e., a first TAG having an association with a first TRP in the first cell, a second TAG having an association with a second TRP in the first cell). The TA of the first TRP is the same as the TA corresponding to the first TAG, and the TA of the second TRP is the same as the TA corresponding to the second TAG. Therefore, the configuration of the TAs of the TRP can be realized by configuring the TAs corresponding to the TAGs. How to configure the TA corresponding to the TAG can be specifically described with reference to fig. 4 and 5 in the corresponding embodiment of fig. 2.

Although NR system Release 16 (Release 16, rel-16) supports multi-TRP (M-TRP) transmission based on multi-DCI (multi DCI), the multi-TRP belongs to the same cell. Since one cell configuration is associated with one TAG and one TAG configures one TA in the current protocol, the current protocol does not support configuring TAs for different TRPs, respectively. However, in case 3 of the embodiment of the present application, a plurality of TAGs may be configured for the first cell, and one TAG for one TA, so that the TAs may be configured for different TRPs belonging to the first cell, i.e., each TRP may be implemented for each TA (per TRP per TA).

Case 4: the first cell is associated with a TAG (such as a first TAG), and the first TAG has an association relationship with a first TRP in the first cell; the TA of the first TRP is the same as the TA corresponding to the first TAG (e.g., the first TA), so that the configuration of the TA of the first TRP can be achieved by configuring the TA corresponding to the first TAG. The TA for the second TRP in the first cell may be determined by the TA for the first TRP or may be indicated by the TAC. For case 4, the foregoing second configuration information may be used to configure a first TAG associated with the first cell, and the foregoing first configuration information may include, but is not limited to, at least one of: identification information of the first TAG (first TAG ID), TAC for indicating the first TA, TAC for indicating the second TA. The TA of how to configure TRP specifically may be referred to as an example diagram of fig. 6, fig. 6 taking the first configuration information carried by MAC CE as an example. In fig. 6, a network device may transmit one MAC CE containing 1 TAG ID field, 2 TAC fields, and reserved field R. Each of Oct1 and Oct2 includes a TAC field, where the TA value indicated by the TAC field in Oct1 is a TA value corresponding to the TAG indicated by the TAG ID field in the MAC CE, where the TAG ID field may be used to indicate the TAG associated with the first cell.

Note that, the TA value indicated by Oct1 in fig. 6 is applicable to the TRP (e.g., the first TRP) associated with the TAG (associated with the first cell), and the TA value indicated by Oct2 is applicable to other TRPs (e.g., TRP other than the first TRP, i.e., the second TRP) in the first cell. In this way, even if the first cell is associated with one TAG, the TA can be configured separately for different TRPs belonging to the first cell, i.e. each TRP can be realized per TA (per TRP per TA).

For case 4, in one implementation, the TAG associated with the first cell may be associated with the first TRP or the second TRP by default. In another implementation, the network device may configure which TRP in the first cell the TAG (associated with the first cell) is associated with.

S703, the terminal equipment obtains the first TA and/or the second TA according to the first configuration information.

After receiving the first configuration information, if the first configuration information is used for configuring the first TA of the first TRP, the terminal device may obtain the first TA according to the first configuration information. If the first configuration information is used for configuring the second TA of the second TRP, the terminal device may obtain the second TA according to the first configuration information. If the first configuration information is used for configuring the first TA of the first TRP and the second TA of the second TRP, the terminal equipment can obtain the first TA and the second TA according to the first configuration information.

By implementing the embodiment of the application, the TA configuration can be performed on one or more TRPs in the first cell, so that time synchronization of the network equipment side is ensured. Specifically, for case 1, multiple TAGs may be configured for the first cell, one TAG for each TA, so that TAs may be configured for different TRPs belonging to the first cell, respectively. For case 2, even if the first cell is associated with one TAG, the TA may be configured separately for different TRPs belonging to the first cell. Both case 1 and case 2 can implement the per TRP per TA.
