Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.

Abstract: This disclosure relates to techniques for performing conditional handovers and cell re-selections along known routes. A cellular base station may select a conditional handover set for a wireless device. The conditional handover set may include information for multiple conditional handovers. The wireless device may receive the conditional handover set. The wireless device may perform conditional handover to at least a first cell indicated in the conditional handover set based at least in part on the conditional handover set.

Abstract: An example technique for security key derivation in a wireless system includes: receiving a radio resource control (RRC) suspend message from a first node, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value, entering a RRC inactive state, deriving a first node key based on the first NCC value, generating a first uplink message for transmission in the RRC inactive state based on the first node key, and transmitting the first uplink message to a node while in the RRC inactive state.

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: Provided is a method by a user equipment (UE), comprising: receiving, from a base station (BS), one or more messages providing different barring configurations for different access identities in an access identity set, the UE has at least one access identity, and the at least one access identity is from the access identity set and indicates that the UE is a disaster inbound roamer with respect to the BS; and performing, by the UE, an access barring check based on the one or more messages.

Abstract: To accommodate a mix of high frequency carriers and lower frequency carriers, a protocol stack may include a radio link control (RLC) entity that allows configuration of status reporting control parameters on per carrier, or per subcarrier spacing. Alternatively, a protocol stack may include two RLC entities, one for handling high frequency carriers, and another for handling lower frequency carriers. (High frequency carriers and lower frequency carriers may be distinguished based on a frequency threshold.) Furthermore, a user equipment may transmit (to the network) an indication of its L2 buffer size. The network may configure the UE and/or control scheduling, to ensure the UE's L2 buffer does not overrun. Alternatively, the UE may indicate that it can support a percentage of a maximum buffer size. The network may configure the UE and/or control scheduling so that the UE's buffer occupancy does not exceed the percentage.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.
