Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may communicate, with a second UE, an indication relating to physical sidelink shared channel (PSSCH) beam training. The UE may transmit, to the second UE on symbols included in a transmission time interval, PSSCH data and beam training reference signals to be used by the second UE to perform beam measurements. Numerous other aspects are described.
Claims30
A method of wireless communication performed by a first user equipment (UE), comprising:
- communicating, with a second UE, an indication identifying a frame structure for physical sidelink shared channel (PSSCH) beam training;
- transmitting sidelink control information (SCI) indicating a transmission time interval for beam training;
- and
- transmitting, based at least in part on the frame structure and to the second UE on symbols included in flail the transmission time interval, PSSCH data and beam training reference signals to be used by the second UE to perform beam measurements.
A method of wireless communication performed by a first user equipment (UE), comprising:
- receiving, from a second UE on symbols included in a control channel of a transmission time interval, physical sidelink shared channel (PSSCH) data and beam training reference signals;
- receiving, from the second UE, sidelink control information (SCI) indicating that the transmission time interval is for beam training;
- decoding the PSSCH data received in the transmission time interval;
- and
- performing beam training based at least in part on the beam training reference signals received in the transmission time interval.
A first user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- communicate, with a second UE, an indication identifying a frame structure for physical sidelink shared channel (PSSCH) beam training;
- transmit sidelink control information (SCI) indicating a transmission time interval for beam training;
- and
- transmit, based at least in part on the frame structure and to the second UE on symbols included in the transmission time interval, PSSCH data and beam training reference signals to be used by the second UE to perform beam measurements.
