Relaying in a device-to-device communication system

Abstract:

The present aspects relate to device-to-device (D2D) relaying in a wireless communication system. In an aspect, a remote user equipment (UE) may transmit, on at least one sidelink channel, a scheduling request to a relay UE connected with a network entity. The remote UE may further receive, on one or more sidelink channels, a scheduling indication including a resource grant from the relay UE in response to transmitting the scheduling request. In a further aspect, a relay UE may receive, on at least one sidelink channel, a scheduling request from a remote UE. The relay UE may further determine, a resource grant for the remote UE in response to receiving the scheduling request. The relay UE may further transmit, on one or more sidelink channels, a scheduling indication including the resource grant to the remote UE.
