To facilitate understanding of the embodiments of the present application, some terms or concepts that may be involved in the present application are described here.

1. Timing in advance

The timing advance means that the sending boundary of the terminal device for the uplink subframe is advanced by a certain period of time relative to the receiving boundary of the downlink frame, and the certain period of time may be called a TA value. The network device controls the TA value of each terminal device based on TA, and controls the time when uplink signals or uplink channels from different terminal devices arrive at the network device, so that the time for uplink signals or uplink channels from different terminal devices to reach the network device is basically aligned.

For example, please refer to FIG. 2. FIG. 2 is a schematic diagram of a timing advance provided by the embodiment of the present application. As shown in FIG. The uplink signal or uplink channel, after a propagation delay of TA/2, the time when the uplink signal or uplink channel arrives at the network device is aligned with the frame boundary of the downlink subframe.

2. Timing advance group

TAG means that the TAs of one or more cells associated with the TAG are the same, that is, the group here is for multiple cells, and the TAs of the multiple cells are the same, it can be said that the multiple cells are associated with the same TAG . In this application, each TAG has a TAG identifier, so in an association relationship, being associated with a TAG can also be understood as being associated with a TAG identifier.

3. Resource configuration information

In an optional implementation manner, the resource configuration information is used to configure an association relationship between uplink signal or uplink channel resources and each TAG.

In another optional implementation manner, the resource configuration information is used to configure an association relationship between uplink signal or uplink channel resources and CORESETPoolIndex. In the existing protocol, it can be considered that one control resource set pool index (CORESETPoolIndex) is associated with one TRP, and different control resource set pool indexes are associated with different TRPs, such as CORESETPoolIndex=0 is associated with one TRP, and CORESETPoolIndex=1 is associated with Another TRP. In other words, if a signal or channel is associated with a control resource set pool index, it can be considered that the signal or channel is associated with the TRP associated with the control resource set pool index, that is, the signal or channel comes from this TRP Send, or send towards this TRP. In this embodiment, the resource configuration information is used to configure the association relationship between uplink signal or uplink channel resource and CORESETPoolIndex, so the terminal can know the association relationship between each uplink signal or uplink channel resource and each TRP.

Wherein, the resource configuration information is configured through radio resource control (radio resource control, RRC), or configured through medium access control-control element (medium access control-control element, MAC-CE).

The embodiments of the present application will be further described below in conjunction with the accompanying drawings.

S101. The network device determines resource configuration information of an uplink signal or an uplink channel;

S102. The network device sends resource configuration information to the terminal device, and the terminal device receives the resource configuration information accordingly;

The resource configuration information needs to configure the association relationship between the resource of the uplink signal or the uplink channel and each TAG. Therefore, the network device needs to determine the TA of the uplink signal or uplink channel for each TRP, and then determine the relationship between the resources of each uplink signal or uplink channel in the resource configuration information and each TAG according to the TA of each TRP's uplink signal or uplink channel. relationship between.

S103. The terminal device determines a timing advance TA of an uplink channel or an uplink signal according to the resource configuration information.

TA value of the signal or uplink channel.

For a PUCCH triggered by downlink control information (DCI), the TRP or CORESETPoolIndex associated with the PUCCH is consistent with the TRP or CORESETPoolIndex associated with the PDCCH carrying the DCI, and then the TAG associated with the PUCCH can be known. Similarly, for a PUSCH triggered by DCI, the TRP or CORESETPoolIndex associated with the PUSCH is consistent with the TRP or CORESETPoolIndex associated with the PDCCH carrying the DCI, and the terminal device can also know the TAG associated with the PUSCH, and then obtain its TA value.
