TECHNIQUES FOR TRAFFIC STEERING BETWEEN ACCESS LINKS AND SIDELINKS IN WIRELESS COMMUNICATIONS SYSTEMS

Abstract:

Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for a user equipment (UE) to receive a logical channel configuration indicating whether logical channels at the UE are configured to use an access link, a sidelink, or both. A UE may determine that data is available on one or more logical channels and may transmit a buffer status report and a scheduling request to a base station based on the determination. In response, the base station may transmit an uplink grant to the UE allocating resources for transmitting the available data based on the logical channel configuration. The UE may transmit the available data on the access link, the sidelink, or both, based on the received uplink grant, the logical channels to which the available data applies, and the logical channel configuration.
