Sidelink discovery message forwarding

Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for sidelink discovery message forwarding. In some implementations, a first user equipment (UE) may receive a discovery message from a second UE. The discovery message may be part of a beam training procedure between the first UE and the second UE. The first UE may forward the discovery message to one or more other UEs based on a condition associated with one or more forwarding termination parameters being satisfied. The first UE may, in some implementations, select one of a broadcast transmission or a unicast transmission for forwarding the discovery message based on one or more parameters associated with the UE. The first UE may transmit the discovery message from the second UE to the one or more other UEs using the selected broadcast or unicast transmission when the condition is satisfied.

Dependencies are inferred from the claim text.
