Abstract: A method of performing a random access procedure includes randomly selecting a backoff time from within a backoff window ranging from 0 to a specified multiple of a random access preamble unit, waiting until a time initialized with the backoff time expires, and retransmitting a random access preamble.

Abstract: A UE comprises: a memory comprising instructions; and one or more processors in communication with the memory, wherein the one or more processors execute the instructions to: wirelessly communicate with a source node, perform a handover from the source node to a target node using L2 signaling in response to a handover decision between the source node and the target node, and wirelessly communicate with the target node in response to the handover. A method implemented by a UE comprises: wirelessly communicating with a source node; performing a handover from the source node to a target node using L2 signaling and in response to a handover decision; and wirelessly communicating with the target node in response to the handover.

Abstract: A method of performing a random access procedure includes randomly selecting a backoff time from within a backoff window ranging from 0 to a specified multiple of a random access preamble unit, waiting until a time initialized with the backoff time expires, and retransmitting a random access preamble.

Abstract: A method for operating a transmitting device includes receiving a first packet data convergence protocol (PDCP) protocol data unit (PDU) associated with a first remote device (RD), the first PDCP PDU including at least a first PDCP header, generating a first nested PDCP PDU in accordance with the first PDCP PDU, the first nested PDCP PDU including a second PDCP header and the first PDCP PDU, the second PDCP header comprising a first PDU type indicator indicating that the first nested PDCP PDU includes a first relayed PDCP PDU and a first identifier associated with the first RD, and sending the first nested PDCP PDU on a radio bearer.

Abstract: A method for paging a user equipment (UE) includes receiving a generic page indication for the UE, the generic page indication including a list of radio access networks (RANs), selecting a subset of the list of RANs, sending a RAN-specific page indication for each RAN in the subset of the list of RANs, receiving a first RAN-specific page response associated with the UE, and sending a generic page response corresponding to the first RAN-specific page response.
