    Abstract: Systems and methods for using a relay user equipment (UE) to transport data of interest received from a first remote UE to a second remote UE on a UE to UE relay within a wireless communication system are discussed herein. These methods may be performed at Layer 2 of a protocol stack of the wireless communication system. Data packets sent on the UE to UE relay may include an adaptation header including routing information (e.g., Layer 2 addresses, a bearer-specific index, etc.) for the UE to UE relay. An adaptation layer may accordingly be provided within Layer 2 to decode these adaptation headers. In some cases, a per-bearer approach may be used to map between individual direct bearers of a hop by hop path configuration of the UE to UE relay. Embodiments eschewing the adaptation header and instead using logical channel identifiers (LCIDs) to make routing indications are also described.

    Abstract: A user equipment (UE) is configured to enter a radio resource control (RRC) state with a base station wherein network operations are performed using a main radio (MR), receive a first set of parameters from the base station for wakeup radio (WUR) state operation wherein the UE enables a WUR and powers down the MR to an off or deep sleep state, the first set of parameters including a parameter enabling the WUR state operation and a configuration of WUR reference signaling (WUR-RS), receive a second set of parameters from the base station for WUR setup and a WUR signal (WUR-S) configuration and enter the WUR state from the RRC state, wherein, while in the WUR state, the UE performs uses the WUR including at least one of monitoring for the WUR-S, measuring the WUR-RS, or implementing a WUR discontinuous reception (DRX) cycle for WUR-S and WUR-RS signal monitoring.
