  • Publication number: 20240064602
    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.

  • Publication number: 20240056867
    Abstract: Systems and methods for performing measurements of one or more cells during an small data transmission (SDT) procedure between a user equipment (UE) and a network when the UE is in a radio resource control (RRC) INACTIVE state are described herein. Beam and/or cell measurements taken during an SDT measurement period of the SDT procedure may be used to determine one or more respective cell qualities, among other possibilities. Beginnings and endings of the SDT measurement period, and the manner (timing) for taking measurements within the SDT measurement period, are also described. The cell qualities so determined can then be used to monitor, during the SDT measurement period, for a measurement event, which causes the UE to send a measurement report to the network having data determined using those cell qualities, and/or to send messaging intended to induce the network to change the RRC state of the UE.

  • Publication number: 20240049068
    Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for a user equipment (UE) having dual connectivity. The UE can communicate with a first primary base station in a first primary cell (PCell) and a second primary base station in a second PCell. The UE has dual connectivity in the second PCell using a first wireless carrier to communicate with the second primary base station and a second wireless carrier to communicate with a secondary base station in a primary secondary cell (PSCell). The UE receives a message from the first primary base station to perform a handover procedure. The UE performs the handover procedure according to the received message, and further perform an addition procedure for the secondary base station in parallel with the handover procedure. A start time of the addition procedure can be before an end time of the handover procedure.
