Abstract: A user equipment (UE) may camp on a base station of a network. The UE receives, from the base station of a wireless network, a broadcast including access restrictions, wherein the access restrictions include one or more predetermined criteria that must be satisfied to camp on the base station. The UE then determines whether the UE satisfies the one or more predetermined criteria.

Abstract: A base station may operate in a context where the propagation delay between the base station and user equipment (UE) devices is large. The base station configures UE devices with a common delay. The base station receives a random access preamble from a UE device. The base station determines a time slot in which the random access preamble was transmitted, based on a configured correspondence between allowable time slots and subsets of an available set of preambles. The base station computes a Random Access Radio Network Temporary Identifier (RA-RNTI) based on parameter values including an index of the determined time slot. The base station employs the computed RA-RNTI to address a random access response for the UE device.

Abstract: A user equipment (UE) device may perform random access to a base station in the context where propagation delay between the base station and the UE device is large. The UE device randomly selects a random access preamble from an available set of preambles. The UE device selects a time slot for transmission of the random access preamble based on a configured correspondence between allowable time slots and subsets of the available set. The UE device transmits the random access preamble to a base station in the selected time slot, with timing advance to compensate for a common delay. Thus, the base station, knowing the configured correspondence, is able to determine the time slot in which the random access preamble was transmitted. The UE device receives a random access response that has been addressed with a Random Access Radio Network Temporary Identifier (RA-RNTI).

Abstract: A first user equipment (UE) is capable of serving as a relay for a second UE using a sidelink connection. The first UE determines that a predetermined condition is satisfied, the predetermined condition associated with the first UE operating as a relay for a second UE, transmits a discovery message and monitors for a signal from the second UE in response to the discovery message.

Abstract: A network configures and transmits paging information. The network transmits configuration information to a user equipment (UE) operating in the network, wherein the configuration information comprises a value N based on a minimum gap between reception of a paging downlink control information (DCI) by the UE and fully processing the paging DCI by the UE, configures a paging DCI to be transmitted to the UE on a Physical Downlink Control Channel (PDCCH), wherein the paging DCI includes scheduling information for a Physical Downlink Shared Channel (PDSCH) and transmits the paging DCI to the UE on the PDCCH.

Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a given SSB may be measured in place of the SSB.
