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: A compressor may obtain information indicative of a transmit delay representative of a time duration that elapses between creation (e.g. by the compressor) of a packet and the transmission of the packet, e.g. over a wireless link. The transmit delay may be determined based at least on information indicative of the uplink capacity of the cellular network. The uplink capacity may be determined/obtained based on the uplink throughput and uplink power headroom. When the compressor receives a negative acknowledgement transmission/packet from the decompressor, if the transmit delay is not greater than a specified threshold value, the compressor may process the received negative acknowledgement packet. If the transmit delay is greater than the specified threshold value, the compressor may first discard the buffered compressed packet scheduled to be transmitted next to the decompressor, and transmit an initialization and refresh (IR) or IR dynamic packet to the decompressor instead.

Abstract: A device may operate within a specified frequency band within a specified coverage area of a wireless cellular network served by a cell. The device may monitor, during a cell-specific paging window, paging messages transmitted by the cell within the cell-specific paging window to devices operating within the specified coverage area and targeted to receive paging messages. The device may enter an idle state if the monitoring indicates that the paging messages do not include a respective paging message intended for the device. If the monitoring indicates that the paging messages include a paging message intended for the device, the device may process the paging message. Furthermore, the device may indicate to the cell, when attaching to the cell, whether the device has a capability to support standalone operation within the specified frequency band. If the indication is that the device does not support such standalone operation, the cell may not issue paging messages to the device.

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: 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 cell re-selection while in an inactive state in a cellular communication system. A wireless device may establish a radio resource control connection with a cellular base station. The wireless device may receive an indication to enter a radio resource control inactive state. The wireless device may perform cell re-selection while in the radio resource control inactive state. Cells that are in the current radio access network notification area of the wireless device may be prioritized over cells that are not in the current radio access network notification area of the wireless device when performing cell re-selection while in the radio resource control inactive state.

Abstract: This disclosure relates to detecting duplicate public warning system messages in a cellular communication system. A wireless device may receive a public warning system indication from a cellular base station during a paging occasion. The public warning system indication may indicate that system information provided by the cellular base station includes a public warning system message. The wireless device may determine whether the public warning system message is a duplicate public warning system message. The wireless device may determine whether to decode the system information including the public warning system message based at least in part on whether the public warning system message is a duplicate public warning system message. The system information including the public warning system message may not be decoded if the public warning system message is determined to be a duplicate public warning system message.

Abstract: A transmitter (e.g. a packet data convergence protocol, PDCP, in the transmitter), which may be a base station for downlink communications or a user equipment device for uplink communications, may control timing of the delivery of duplicate (same) packets to multiple (e.g. two) wireless links (e.g. radio link control links) for transmission to a receiver, based at least on synchronization information received from the receiver. The duplicate packets may be transmitted over the multiple wireless links to the receiver, which may receive the duplicate packets over the multiple wireless links. The receiver may collect and/or generate synchronization information indicative of the timing or latency between the multiple wireless links, based at least on the respective receive timings of the duplicate packets over the multiple wireless links. The receiver may transmit a report containing the synchronization information to the transmitter periodically and/or in response to a trigger event.
