The technical solution provided by the present application can implement SRS antenna selection of three antenna groups. Mapping of Antenna Port to Physical Antenna Port: There is no strict mapping of antenna ports to physical antenna ports in NR as well as in LTE. For example, for a 1T4R NR SRS antenna-switching capability, the NR SRS may switch across four antennas even if the LTE Tx is blanked due to shared cross-switch/antennas. The application provides a method for transmitting a sounding reference signal, which is characterized by comprising the following steps: the terminal equipment transmits the number n according to the SRS SRS And the antenna group number Lambda is selected from the Lambda antenna groups with the serial number a (n) SRS ) Such that each of the Λ antenna groups transmits the SRS at least once .

For the special case of 1T4R antenna switching with aperiodic SRS requiring two slots to complete, an exception is made such that two aperiodic sets may be configured, thus allowing a split of the four resources across two different slots (either as a 2+2 split or a 1+3 split). 11A, the first switch 1140-1 is coupled to the third switch 1140-3, and the second switch 1140-2 is coupled to the fourth switch 1140-4. UE performs antenna switching in various way depending on RRC parameter setting in SRS-ResourceSet as described in 38.214 6.2.1.2. 8.15 would imply that the UE needs to report 1T1R capability since it can only transmit SRS from one of the receive antennas as there is no antenna switching implemented. For SRS antenna switching with 1T4R, it is contemplated that N p =1 and that the eNB configures four different SRS resources for Λ p =4 antennas. module is coupled to the multiple antennas via the switch pair. Here, UE capabilities that indicate that the UE support such switching are defined as 1T2R, 1T4R, or 2T4R. So the first step is to create a proper sequence for SRS and this process is pretty simple as follows. SRS gives information about the combined effect of multipath fading, scattering, Doppler and power loss of transmitted signal. MWC22 Barcelona runs from February 28 to March 3 in Barcelona, Spain.
