Document Type and Number:
WIPO Patent Application WO/2019/158064
Kind Code:
A1
Abstract:
Provided in the present application is a method for transmitting a sounding reference signal (SRS), comprising: determining the number of ports corresponding to each SRS resource among a plurality of SRS resources on a first time domain resource, the plurality of SRS resources belonging to a first SRS resource set; determining the transmission power of each port corresponding to each SRS resource among the plurality of SRS resources according to the number of ports corresponding to each SRS resource among the plurality of SRS resources and transmission power that corresponds to the first SRS resource set on a first time unit, wherein a sum of the transmission power of all the ports corresponding to the plurality of SRS resources is less than or equal to the transmission power corresponding to the first SRS resource set, the first time unit comprises the first time domain resource, or the first time unit is the first time domain resource; simultaneously transmitting SRSs carried by the plurality of SRS resources on the first time domain resource according to the transmission power of each port. The described method may support the allocation of transmission power of respective ports when a plurality of SRSs are simultaneously transmitted.
