name: U2U
full_form: UE-to-UE
context: Bearers (SL-SRBs or SL-DRBs) towards the same peer L2 U2U Remote UE and/or different peer L2 U2U Remote UEs can be multiplexed to the same PC5 Relay RLC channel, which is between the L2 U2U Remote UE(s) and the L2 U2U Relay UE. - For the traffic received at L2 U2U Remote UE, the same PC5 Relay RLC channel from one L2 U2U Relay UE can be de-multiplexed to the different end-to-end PC5 Radio Bearers (SL-SRBs or SL-DRBs) of the same peer L2 U2U Remote UE and/or different peer L2 U2U Remote UEs. - The SRAP sublayer at L2 U2U Remote UE supports identification of the peer L2 U2U Remote UE and itself. The local IDs are assigned by L2 U2U Relay UE to both L2 U2U Remote UEs for identification. For the two local IDs, one of them identifies L2 U2U Remote UE and the other identifies the peer L2 U2U Remote UE. The local ID of the peer L2 U2U Remote UE and the local ID of L2 U2U Remote UE are delivered by L2 U2U Relay UE to the L2 U2U Remote UEs along with the corresponding L2 ID of the peer L2 U2U
description: A communication link between two User Equipments (UEs) facilitated by a relay UE, enabling data transmission and multiplexing of bearers over a shared PC5 Relay RLC channel.
explanation: The context describes U2U as a connection between L2 U2U Remote UEs, with the involvement of an L2 U2U Relay UE for multiplexing and de-multiplexing of bearers. This indicates that U2U refers to a specific type of communication link or connection in the 3GPP specification.
