Title:
SOUNDING REFERENCE SIGNAL TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2019/218108
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to methods, devices and computer readable mediums for sounding reference signal (SRS) transmission. In example embodiments, a method implemented at a terminal device is provided. According to the method, in response to at least one set of SRS resources being configured for transmitting a SRS to a network device and antenna switching being enabled for the terminal device, the terminal device determines at least one guard period required for transmitting the SRS. Uplink transmission to the network device is expected to be scheduled outside the at least one guard period. In response to the uplink transmission being scheduled outside the at least one guard period, the terminal device transmits the SRS to the network device over the at least one set of SRS resources. In response to the uplink transmission being scheduled within the at least one guard period, the terminal device disables at least a part of the at least one set of SRS resources for transmitting the SRS.
