    Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for determining resources for scheduling side-link communications. The resources may be semi-persistent and/or dynamic resources. A user equipment device (UE) may determine a resource map for use in scheduling semi-persistent resources for side-link communications with at least one wireless node. The UE may transmit a resource map request message indicating preferred resource blocks, where each resource block may be defined by a time and a frequency. The UE may receive a confirmation message that may include a report regarding a set of resource blocks. The set of resource blocks may be from the preferred resource blocks included in the resource map request message. The UE may determine, based, at least in part, on the confirmation message, resource blocks to be used for the side-link communications and initiate the side-link communications using the determined resource blocks.

    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: Base stations, user equipment devices (UEs), and methods for a base station to supply service type-specific information to the UE. The base station may broadcast a first system information block (SIB) comprising scheduling information for a plurality of second SIBs, wherein each of the plurality of second SIBs corresponds to a respective service type of a plurality of service types, and wherein the second SIBs describe service type-specific capabilities of the base station. The plurality of service types may comprise two or more of enhanced mobile broadband, ultra-reliable low latency communications, and massive machine-type communications. The base station may broadcast the plurality of second SIBs according to the scheduling information of the first SIB, and may establish a connection and communicate with the UE using one or more service types and according to the service type-specific capabilities described by second SIBs corresponding to the one or more service types.

    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.
