Abstract:
A method for configuring aperiodic sounding reference symbols is disclosed. The method avoids transmission of unused configuration parameters. In particular, parameters for use with DCI format 4 are not configured for user equipment that does not support the format. Accordingly, the method may include: configuring UL transmission mode equal to 1; configuring aperiodic SRS for DCI format 0/1a; and not configuring aperiodic SRS parameter sets for DCI format 4. The method may also include: configuring UL transmission mode equal to 2; configuring aperiodic SRS for DCI format 0/1a; and not configuring aperiodic SRS parameter sets for DCI format 4.
