To facilitate an understanding of the embodiments of the present application, some terms or concepts that may be referred to herein are set forth.
1. Timing advance
The timing advance is that the sending boundary of the terminal equipment for the uplink subframe is advanced relative to the receiving boundary of the downlink frame by a certain time length, and the size of the certain time length can be called as a TA value. The network device controls the TA value of each terminal device based on the TA, and controls the time when the uplink signal or uplink channel from different terminal devices arrives at the network device, so that the time when the uplink signal or uplink channel from different terminal devices arrives at the network device is basically aligned.
For example, referring to fig. 2, fig. 2 is a schematic diagram of timing advance provided in the embodiment of the present application, as shown in fig. 2, a terminal device sends an uplink signal or an uplink channel with respect to a sending boundary of an uplink subframe and a receiving boundary of a downlink subframe by a time period TA, and after the uplink signal or the uplink channel passes through a propagation delay TA/2, a time when the uplink signal or the uplink channel arrives at a network device is aligned with a frame boundary of the downlink subframe.
2. Timing advance group
TAG means that the TA of 1 or more cells associated with the TAG are the same, i.e. the group here is for a plurality of cells whose TA are the same, which may be referred to as the plurality of cells associating the same TAG. In this application, each TAG has a TAG identifier, so that association with one TAG in the association relationship can be understood as association with one TAG identifier.
3. Resource configuration information
In an optional implementation manner, the resource configuration information is used for configuring an association relationship between resources of an uplink signal or an uplink channel and TAGs.
In another alternative embodiment, the resource configuration information is used to configure an association between the resources of the uplink signal or the uplink channel and the coresetpoolndex. In existing protocols, one control resource set pool index (coresetpoolndex) may be considered to be associated with one TRP, different control resource set pool indexes being associated with different TRPs, e.g. coresetpoolndex=0 being associated with one TRP, CORESETPoolIndex =1 being associated with another TRP. In other words, if a signal or channel is associated with a certain 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, i.e. the signal or channel is transmitted from or towards the TRP. In this embodiment, the resource allocation information is used to allocate the association between the resources of the uplink signal or the uplink channel and the coresetpoolndex, so that the terminal can obtain the association between the resources of each uplink signal or uplink channel and each TRP.
Wherein the resource configuration information is configured through radio resource control (radio resource control, RRC) or through a medium access control-element (MAC-CE).
Embodiments of the present application are further described below with reference to the accompanying drawings.
Referring to fig. 3, fig. 3 is a flowchart of a timing advance determining method 100 according to an embodiment of the present application. As shown in fig. 3, the timing advance determination method 100 includes, but is not limited to, the steps of:
s101, network equipment determines resource allocation information of an uplink signal or an uplink channel;
s102, the network equipment sends resource configuration information to the terminal equipment, and correspondingly, the terminal equipment receives the resource configuration information;
and because the association relation between the uplink signal or the uplink channel resource and each TAG is required to be configured in the resource configuration information. Therefore, the network device needs to determine the TA of the uplink signal or the uplink channel for each TRP, and further determine the association relationship between the resources of each uplink signal or uplink channel in the resource configuration information and each TAG according to the TA of the uplink signal or the uplink channel for each TRP.
S103, the terminal equipment determines timing advance TA of the uplink channel or the uplink signal according to the resource configuration information.
And the terminal can obtain the TA of each uplink signal or uplink channel according to the association relationship between the resources of each uplink signal or uplink channel configured in the resource configuration information and each TAG.
Therefore, through the association relationship between the resources of the uplink signal or the uplink channel and the TAGs in the resource configuration information, the TA enhancement aiming at each TRP can be realized, and the alignment effect of the uplink signal or the uplink channel is further improved.
The embodiment of the present application further provides a timing advance determination method 200, where the timing advance determination method 200 is different from the timing advance determination method 100 described above in that the resource configuration information is used to configure an association relationship between resources of an uplink signal or an uplink channel and coresetpoolndex.
The terminal equipment can acquire the association relation between the CORESETPoollIndex and each TAG, so that the terminal equipment can determine the association relation between the uplink signal or the uplink channel resource and each TAG according to the resource allocation information in the method, and the TA value of each uplink signal or each uplink channel can be determined. Therefore, through the association relationship between the resources of the uplink signal or the uplink channel and each coresetpoolndex in the resource configuration information, the TA enhancement for each TRP can be realized, and the alignment effect of the uplink signal or the uplink channel is further improved.
Optionally, in the timing advance determination method 200, there is an association relationship between the coresetpooolindex and each TAG, and the association relationship between the coresetpooolindex and each TAG is predefined or configured by the network device for the terminal device, such as configured in an RRC or MAC-CE manner.

That is, in the timing advance determination method 100, for periodic PUCCH or semi-persistent scheduled PUCCH, the network device may configure its associated TAG through RRC or MAC-CE to obtain its TA value.
In the timing advance determination method 200, for periodic PUCCH or semi-persistent scheduled PUCCH, the network device may configure its associated coresetpoolndex through RRC or MAC-CE. And the terminal equipment determines the periodic PUCCH or the TAG associated with the semi-persistent scheduling PUCCH based on the association relation between the CORESETPoolIndex and the TAG, and further obtains the TA value of the terminal equipment.
For the PUCCH triggered by the downlink control information (downlink control information, DCI), the TRP or coresetpoolndex associated with the PUCCH is identical to the TRP or coresetpoolndex associated with the PDCCH carrying the DCI, so that the TAG associated with the PUCCH can be obtained. Similarly, for the PUSCH triggered by DCI, the TRP or coresetpoolndex associated with PUSCH is consistent with the TRP or coresetpoolndex associated with PDCCH carrying the DCI, and the terminal device can also obtain the TAG associated with PUSCH, thereby obtaining the TA value thereof.

That is, in the timing advance determination method 200, for PUSCH of configuration grant type 1, the network device may configure its associated TAG through RRC or MAC-CE to obtain its TA value.
In the timing advance determining method 200, for PUSCH of configuration grant type 1, the network device may configure its associated corespoolindex through RRC or MAC-CE, and then the terminal device determines, based on the association relationship between corespoolindex and each TAG, the TAG associated with the periodic PUCCH or the semi-persistent scheduled PUCCH, and further obtains the TA value thereof.
In an alternative embodiment, the uplink signal is a channel sounding reference signal (Sounding reference signal, SRS).
That is, in the timing advance determination method 100, for SRS, the network device may configure its associated TAG through RRC or MAC CE to obtain its TA value.
In the timing advance determination method 200, for SRS, the network device may configure its associated coresetpoolndex through RRC or MAC CE, and the terminal device may learn the TAG associated with SRS, and further obtain its TA value. Alternatively, the SRS may be a periodically or continuously scheduled SRS.
In an alternative embodiment, for the timing advance determination method 100, the uplink signal or the resource of the uplink channel is associated with the second TAG or the first TAG or the largest TAG of the serving cell. Wherein the serving cell is a cell in which the terminal device resides. One cell may be associated with multiple TAGs, and this embodiment may clarify one TAG that the terminal device may use.
In an alternative embodiment, for the timing advance determination method 200, the control resource set pool coresetpoolndex of the resource association of the uplink signal or the uplink channel has a value equal to the first value.
