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: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

Abstract: Techniques are disclosed relating to reporting channel state information (CSI) when synchronization state is altered. In some embodiments, a UE starts a timing alignment timer (TAT) in response to a time alignment command (TAC) from a cellular network for one or more serving cells. In some embodiments, the UE stores a configuration for a semi-persistent (SP) channel state information (CSI) report for the apparatus over a physical uplink shared channel (PUSCH). In some embodiments, the UE activates the SP-CSI report based on downlink control information (DCI) from the network. In some embodiments, the UE transmits one or more SP-CSI reports according to the configuration. In some embodiments, in response to expiration of the TAT, the UE deactivates all active stored configurations of SP-CSI reports that use the PUSCH and that correspond to the one or more serving cells. In some embodiments, this may avoid collisions with PUSCH transmissions from other UEs, e.g., when the UE returns to an in-sync state.

Abstract: This disclosure relates to performing bandwidth part activation in a cellular communication system. A wireless device may attach to a network via a cell that includes multiple bandwidth parts. The wireless device may receive an indication activating a non-default bandwidth part for the wireless device. A bandwidth part activation timer may be initiated based at least in part on activation of the non-default bandwidth part. At expiration of the bandwidth part activation timer, the wireless device may deactivate the non-default bandwidth part and activate a default bandwidth part if there is not a procedure to perform an uplink data transfer in progress. If there is a procedure to perform an uplink data transfer in progress at expiration of the bandwidth part activation timer, the procedure may be completed via the non-default BWP even after expiration of the bandwidth part activation timer.

Abstract: One embodiment described herein takes the form of a user equipment (UE), such as a phone. The UE includes a transceiver and a processor. The processor is configured to associate with a secondary UE for collaborative transmission of a data payload of one of the UE or the secondary UE to a base station. The processor is configured to determine a link quality with the base station or the secondary UE, and determine a location of the UE or the secondary UE while associated with the secondary UE. The processor is configured to transmit to the base station or the secondary UE at least the determined link quality or the determined location, and determine to maintain, re-establish, or disable the association with the secondary UE based on at least one of a number of factors including: the determined link quality, the determined location, or an indication received from the base station.

Abstract: A user equipment (UE), baseband processor or other network device (e.g., base station, next generation NodeB, etc. ) can operate to process or generate measurement gap configurations associated with multiple universal subscriber identity modules (MUSIM) with dual subscriber identify modules (SIMs). A UE can perform a system information request or an SI reading with or without the SI request based on a UE configured interruption or a preconfigured measurement gap configuration to read a system information block (SIB) 1 and at least one other SIB of SI associated with the target network.
