Abstract
A cellular base station (BS) which determines an aperiodic sounding reference signal (SRS) triggering offset configuration specifying an offset between an aperiodic SRS trigger received by a user equipment (UE) and transmission of the SRS by the UE. The cellular base station may determine that the SRS triggering offset should be adjusted. In response, the cellular base station may transmit signaling to the UE specifying a new value for the aperiodic SRS triggering offset. The new SRS triggering offset value may be partly based on a minimum timing offset for the UE and may be contained in a medium access control (MAC) control element (CE) or in downlink control information (DCI). Additionally, the new triggering offset value may be applicable for a plurality of component carriers or bandwidth parts. The cellular base station may also determine a new triggering offset value due to conflicts regarding the AP-SRS transmission.
