Abstract: A user equipment (UE), next generation NodeB (gNB), or other network component can operate to configure a group configuration message that initiates a plurality of UEs in a coverage area of a non-terrestrial network (NTN) to concurrently transfer communication from a first beam of a first satellite to a second beam of a second satellite. The communications of one or more UEs can be re-directed to the second beam of the second satellite based on downlink control information of the group configuration message.

Abstract: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Abstract: Provided is a method for a user equipment (UE). The UE generates a first information for the UE for transmission to a network device. The first information is associated with a small data transmission (SDT) procedure in an inactive state of the UE. The UE obtains a first configuration information from the network device. The first configuration information is determined with reference to the first information. The UE determines whether to perform the SDT procedure in the inactive state according to the first configuration information. The UE, in response to determining to perform the SDT procedure in the inactive state, performs the SDT procedure in the inactive state according to the first configuration information.

Abstract: This disclosure relates to performing beam failure recovery using a contention based random access procedure in a cellular communication system. A wireless device and a cellular base station may establish a cellular link. Beam configuration information indicating an active beam for downlink communications may be provided. The wireless device may detect beam failure for the active beam. The wireless device may perform a contention based random access procedure based at least in part on detecting beam failure for the active beam. An indication of the detected beam failure may be provided to the cellular base station by the wireless device as part of the contention based random access procedure.

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: This disclosure relates to techniques for determining a quasi-co-located assumption for aperiodic channel state information reference signals for multi-transmission-reception-point operation in a wireless communication system. A wireless device may establish wireless links with multiple transmission-reception-points of a cellular network. The wireless device may receive downlink control information. The wireless device may determine a quasi-co-located assumption for aperiodic channel state information reference signals for the downlink control information. Signals received according to the quasi-co-located assumption for aperiodic channel state information reference signals may be buffered by the wireless device if a scheduling offset for the downlink control information is below a scheduling offset threshold.

Abstract: Apparatuses, systems, and methods for user equipment device (UE) uplink antenna panel selection. The UE may determine, based on at least one condition, to perform a beam switch from a current beam being used for communications with a base station. The UE may transmit, to the base station, an indication of an antenna panel status that may include an indication of a latency associated with the beam switch. The UE may receive, from the base station, an indication to switch to a target beam and to perform the switch, based on the indication, to the target beam. The indication of the antenna panel status may include a beam switching latency level for each beam in a beam report, a beam switch request that may indicate the target beam, and/or a beam switch request that may indicate that an antenna panel switch is to be applied by the UE.
