In the embodiment of the present application, determining the transmission of the sounding reference signal specifically refers to determining a transmission mode and a transmission power of the sounding reference signal and a spatial relationship when the sounding reference signal is transmitted. Specifically, the transmission mode includes, for example, an aggregate transmission, a non-aggregate transmission, in which order or priority the transmission is performed, and the like. The transmit power is then specific to the transmit power of each or every sounding reference signal. It should be noted that the transmission mode, the transmission power and the spatial relationship of the first sounding reference signal transmitted in the aggregation are important contents of the present application. Through effective control, the first detection reference signal can be better assisted in position measurement, and higher positioning accuracy can be obtained. Since the total power of the terminal for transmitting the sounding reference signal is fixed, the transmission power of some sounding reference signals can be configured and set according to parameters such as priorities, carrier bandwidth ratios and the like of different sounding reference signals. Determining the transmission of the sounding reference signal further includes determining a spatial relationship of the sounding reference signal, where the spatial relationship of the plurality of sounding reference signals may be consistent or inconsistent.

And determining according to the third priority rule which configuration information the sounding reference signal is actually sent according to. It can be understood that one or more sounding reference signals are generally configured according to configuration information of the sounding reference signal with the highest priority. In an embodiment, if different configuration information is configured for a plurality of first carriers or first units, the sounding reference signal determines, according to a priority or a third priority rule, the configuration information used for sending the sounding reference signal. For another example, when multiple sounding reference signals are aggregated to be a first sounding reference signal, the configuration information of the multiple sounding reference signals is different, and the configuration information of the first sounding reference signal is determined according to a priority or a third priority rule.
And configuring the spatial relationship of the plurality of sounding reference signals according to a fourth priority rule. It can be understood that priority guarantees that the spatial relationship of the sounding reference signal with higher priority is successfully configured. Or it can be understood that, sounding reference signals transmitted simultaneously or on multiple carriers transmitted in an overlapping manner have different spatial relationships, and the spatial relationship of the sounding reference signals is determined according to a priority rule or a fourth priority rule. In one embodiment, 3 sounding reference signals are configured with spatial relationship 1, spatial relationship 2, and spatial relationship 3, respectively. However, the terminal can only transmit the sounding reference signal according to one spatial relationship or two spatial relationships at the same time within a certain time.

Assuming that events A, B, C and D are present, the protocol may specify a priority for at least one of A, B, C, D and may also specify an order of the A, B, C, D events. Of which A, B, C, D are merely illustrative examples, there may be more or fewer events.

The first priority rule further includes a power allocation priority of the plurality of sounding reference signals, that is, a priority order of some or some sounding reference signals or carriers in the plurality of sounding reference signals or the plurality of carriers corresponding to the sounding reference signals is determined, it can be understood that the priority ensures that the transmission power of the sounding reference signal with higher priority or the carrier corresponding to the sounding reference signal is configured.

The first priority rule further comprises a power allocation priority of other signals or channels, the other signals or channels being different signals or channels than the sounding reference signal. It will be appreciated that the power allocation of the other signals or channels is determined according to a priority or priority rule. It can also be understood that the transmission power of other signals or channels is determined according to the priority on the premise of ensuring that the transmission power of the reference sounding signal is configured. And can be understood as the priority of the transmission power of the sounding reference signal and the power allocation of other signals or channels.
The first priority rule further comprises a power allocation priority of the first sounding reference signal and the other signal or channel. Specifically, the priority of the first sounding reference signal is higher than the priority of other signals or channels, that is, when power allocation is performed on the first sounding reference signal and other signals or channels, it is preferentially guaranteed that the transmission power of the first sounding reference signal is configured, and vice versa.
