Abstract
Methods and apparatus for SL SRS transmission are disclosed. One method of a relay/remote UE comprises transmitting a SRS on a SL. The SRS is based on a SL SRS configuration which configures location information of the SRS in time-frequency domain. The transmission of SRS can be either periodic or aperiodic. Further, the SRS is a single SRS or a set of SRS.
Claims26
An apparatus comprising a first user equipment, the apparatus further comprising:
- a transceiver that:
- receives a sidelink sounding reference signal configuration corresponding to a sounding reference signal (SRS) from a network equipment or a sidelink (SL) apparatus comprising a second user equipment;
- in response to receiving the sidelink sounding reference signal configuration from the network equipment:
- transmits the same sidelink sounding reference signal configuration received from the network equipment to the sidelink apparatus for the sidelink apparatus to be configured with the sidelink sounding reference signal configuration prior to receiving the sounding reference signal;
- and
- transmits the sounding reference signal to the sidelink apparatus;
- and
- in response to receiving the sidelink sounding reference signal configuration from the sidelink apparatus, transmits the sounding reference signal to the sidelink apparatus without transmitting the sidelink sounding reference signal configuration because the sidelink apparatus already is aware of the sidelink sounding reference signal configuration.
