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) may be configured with information to perform conditional handovers or addition/change of a primary secondary cell (PSCell). The UE receives a first radio resource control (RRC) configuration message from the source cell for conditional handover to the at least one target cell, the first RRC configuration message including conditional handover execution conditions, an RRC configuration and a target cell ID for each one of a list of target cells, performs measurements on the target cells to determine whether any one of the target cells fulfills its corresponding conditional handover execution conditions and, when a first target cell from the list of target cells fulfills its corresponding conditional handover execution conditions, initiates a handover to the first target cell.

Abstract: A user equipment (UE) is configured with a carrier aggregation (CA) functionality and UE connected to a network via a base station that serves as a primary serving cell (PCell) providing a primary component carrier (PCC) to the UE. The UE determines a plurality of bands that are supported by the UE for use in the CA functionality, generates an individual band information element (IE) including band information for the bands, determines at least one representative CA combination having an order, the order indicating a total number of component carriers (CCs), the at least one representative CA combination forming a basis to extrapolate a plurality of CA combinations having the order based on the band information, generates a representative CA combination IE including the at least one representative CA combination and transmits the individual band IE and the representative CA combination IE to the base station.

Abstract: A base station may be configured to perform operations related to link management for a remote user equipment (UE). The operations comprising, transmitting configuration information to the remote UE and receiving information corresponding to a serving link associated with the remote UE. The operations further comprising determining that the serving link associated with the remote UE is to be switched from a first communication link to a second communication link. The operations further comprising, transmitting a message to the remote UE indicating that the serving link associated with the remote UE is to be switched from the first communication link to the second communication link. The operations further comprising, transmitting a message to a relay UE. The message is configured to trigger the relay UE to perform an operation corresponding to the serving link associated with the remote UE.
