Abstract: This disclosure relates to techniques for providing broadcast and multicast services to wireless devices while in Idle and Inactive modes a wireless communication system. A wireless device may establish a wireless link with a cellular base station of a cellular network. The wireless device may receive information indicating whether provision of a broadcast or multicast service in one or more of an inactive mode or an idle mode is supported by the cellular network. The wireless device may receive the broadcast or multicast service in one or more of the inactive mode or the idle mode based at least in part on the information indicating whether provision of the broadcast or multicast service in one or more of the inactive mode or the idle mode is supported by the cellular network.

Abstract: Apparatuses, systems, and methods for beam indication latency reduction via symbol level beam sweeping capability reporting. A wireless device may transmit, to a base station, a report associated with symbol level beam sweeping. The wire wireless device may receive, from the base station, a symbol level beam sweeping configuration. The symbol level beam sweeping configuration may be based, at least in part, on the report. The wireless device may perform synchronization signal block (SSB) measurements according to the report and the symbol level beam sweeping configuration.

Abstract: Provided is a method for a user equipment (UE). The method includes determining a mobility state of the UE and performing reference signal measurement in a relaxation mode within at least one cell. The mobility state indicates mobility capability of the UE, and, the at least one cell is determined based on the mobility state.

Abstract: Apparatuses, systems, and methods for application function (AF) key generation and AF key renewal. A user equipment device (UE) may communicate with an application function (AF) via a radio access network (RAN) using a first AF key and determine that the first AF key has expired. The UE may derive a second AF key based on at least an Architecture for Authentication and Key Management for Applications (AKMA) anchor key (KAKMA) and a counter parameter and communicate with the AF via the RAN using the second AF key. At least one of the UE, the AF, and/or an AKMA Anchor Function (AAnF) may be configured to monitor expiration of the first AF key based on an associated lifetime of the first AF key. The first and second AF keys may be derived using a key derivation function that includes at least one variable parameter.

Abstract: Apparatuses, systems, and methods for radio resource management (RRM) signal reception. A user equipment device (UE) may receive, via a first reception path, an RRM related signal and receive, via a second reception path, a non-RRM related signal that may be multiplexed with the RRM related signal onto a symbol. The first reception path may be a first antenna port of an antenna panel or a first antenna panel of the UE and the second reception path may be a second antenna port of the antenna panel or a second antenna panel of the UE. The RRM related signal may include a reference signal for RRM. and may be included in a non-zero power (NZP) interference measurement.

Abstract: A user equipment (UE) communicates with transmission-reception points (TRPs). When the UE generates uplink control information (UCI), it determines a higher layer index (HLI) value to target the UCI to the appropriate TRP. (Possible values of the HLI are associated with the TRPs.) For UCI on Physical Uplink Control Channel (PUCCH), the HLI value may be determined: based on an HLI value configured for a control resource set (CORESET), or for particular Physical Uplink Control Channel (PUCCH) resources; based on UCI type or spatial relation data or an index related to PUCCH resources. For UCI on a configured-grant Physical Uplink Shared Channel (PUSCH), the HLI value may be based on higher layer signals or an indicator relating to channel sounding on spatial relation data. For UCI on MsgA PUSCH in a two-step random access procedure, the HLI value may be based on PUSCH resource unit or PUSCH opportunity.

Abstract: This disclosure relates to techniques for performing relay communication by a relay wireless device in a wireless communication system. A relay wireless device may receive bearer configuration information from a network. Based on the bearer configuration information, the UE may establish a bearer with a remote wireless device. The relay wireless device may forward data to/from the remote wireless device using the bearer.
