| 主权项 | 1. A non-transitory computer readable medium having stored therein computer executable instructions for implementing a method in a user equipment, the method comprising: controlling a receiver to use discontinuous reception associated with configured on periods and off periods; maintaining a configuration of a set of sounding reference signal transmission resources; transmitting a request for an uplink transmission resource during one of the off periods; and transmitting a sounding reference signal transmission, using at least one of the set of sounding reference signal transmission resources associated with the configuration, responsive to transmitting the request for the uplink transmission resource. | ||
