| 主权项 | 1. A method in a user equipment comprising: controlling a receiver to monitor a control channel during a discontinuous reception (DRX) active time; stopping from transmitting an uplink sounding reference signal (SRS) responsive to said DRX active time ending; and maintaining an SRS resource configuration for the user equipment after said DRX active time ends, wherein the SRS resource configuration is associated with a time-frequency resource; and restarting transmission of SRS responsive to said DRX active time restarting. | ||
