Abstract: Adjusting search and measurement periodicity based on device motion. A wireless device may camp on a serving cell. Signal strength, signal quality, and signal to noise ratio of the serving cell may be measured. If each is above a respective threshold, and if the wireless device is stationary, the periodicities at which searches and neighbor cell measurements are performed may be adjusted (e.g., increased) from baseline periodicities.

Abstract: Throttling of transition attempts to connected mode based on user context. A wireless device may camp on a serving cell. A motion state of the wireless device may be monitored. One or more connected mode transition procedures on the serving cell may be attempted. If at least a threshold number of connected mode transition procedures fail on the serving cell while the wireless device is stationary, further connected mode transition attempts may be throttled for up to a certain amount of time. Alternatively, or in addition, the wireless device may bar itself from camping on that cell for up to a certain amount of time. Either or both of throttling connected mode transition attempts or barring cells may also be based on other aspects of user context, such as display state.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

Abstract: This disclosure relates to providing early packet delivery to radio link control. A transport block may be received by a wireless device via wireless communication. The transport block may fail a transport block cyclic redundancy check, but a subset of the code blocks of the transport block may pass code block cyclic redundancy checks. Packet data from the subset of the code blocks that pass code block cyclic redundancy checks may be provided to a radio link control layer of the wireless device, based at least in part on the successful code block cyclic redundancy checks for those code blocks.

Abstract: This disclosure relates to techniques for performing radio resource control procedures for remote wireless devices in a wireless communication system. A remote wireless device may transmit a radio resource control message that includes information configured to be relayed to a cellular base station to a relay wireless device, which may relay the information to the cellular base station. The cellular base station may also transmit a radio resource control message that includes information configured to be relayed to the remote wireless device to the relay wireless device, which may relay the information to the remote wireless device.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for mitigation of secondary cell failures. A user equipment (UE) may establish communication with a macro cellular base station. The UE may perform a signal quality measurement of a small cell base station and compare the signal quality measurement to a threshold. Based on the signal quality measurement exceeding the threshold, the UE may attempt to additionally connect to the small cell base station. In response to a radio link failure of the second base station, the UE may modify the first threshold. In response to subsequent failures to additionally connect to the small cell base station using the modified first threshold, the UE may disable connections to the small cell base station.

Abstract: A network device or component such as an access node (AN) can operate to provide a request to obtain a network slice of a network slice as a service (NSaaS) to provide a communication service on the network slice for an end-user device. In response to obtaining the network slice, a network slice customer (NSC) Service identity (ID) associated with the network slice can be determined and provided for a communication service for an application by the end-user device or user equipment (UE). The request can be processed at a network slice provider (NSP) component, in which the network slice can be assigned to the NSC in response to the request by the NSC. The NSP further provides a user equipment (UE) route selection policy (URSP) comprising a traffic descriptor that includes the NSC Service ID to the NSC.
