    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 base station and a user equipment (UE) communicate the configure uplink communications in a multi-transmission and reception point (multi-TRP) configured network. The UE receives an indication of multiple sounding reference signal (SRS) resources that are to be used for uplink beam tracking, wherein each SRS resource is associated with different spatial relation information, transmits SRS using the associated spatial relation information, receives an indication that a user equipment (UE) is configured with one or more beam pairs, the one or more beam pairs configured by the network based on the SRS and transmits an uplink channel based on the indicated one or more beam pairs.
