  • Publication number: 20240172097
    Abstract: Methods, systems, and Instructions are disclosed to support restricted Proximity-based Services (ProSe) direct discovery in a wireless network. In one embodiment, a method is performed by a first network function (NF), where a terminal device communicates with another terminal device based on the restricted ProSe direct discovery. The wireless network is to assign one ProSe Discovery user equipment (UE) identifier (PDUID) to the terminal device to identify the terminal device in the restricted ProSe direct discovery. The method comprises receiving a request message including a UE identifier (UE ID), where the UE ID uniquely identifies the UE in the wireless network; generating a ProSe Discovery user equipment (UE) identifier (PDUID) for the UE ID based on the UE ID; and transmitting a PDUID information message to a second NF, where the PDUID information message comprises the PDUID and a validity timer.

  • Publication number: 20240056874
    Abstract: A relay UE (502) having a PC5 link with a remote UE (501) creates a modified downlink (DL) packet by adding one or more reflective quality-of-service (QoS) indicators to the DL packet and transmits the modified DL packet on the PC5 link in a PC5 QoS flow to the remote UE. The remote UE receives the modified DL packet, uses the one or more reflective QoS indicators to derive one or more mapping relations, and applies the one or more derived mapping relations to map an uplink (UL) packet to the QoS flow and transmit the UL packet on the PC5 link. The relay UE receives the UL packet and transmits the UL packet to a network node (504) or a second relay UE.
