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 techniques for a wireless device to report uncategorized data in a buffer status report. A first portion of buffered uplink data to be reported in a buffer status report may be categorized using a traffic flow template. A second portion of buffered uplink data to be reported in the buffer status report may not be categorized using the traffic flow template. A buffer status report indicating both the categorized and the uncategorized buffered uplink data may be transmitted to a base station providing a serving cell to the wireless device. According to some embodiments, the categorized buffered uplink data may be stored in a baseband processor buffer of the wireless device, while the uncategorized buffered uplink data may be stored in an application processor buffer of the wireless device.

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: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) receiving from a network entity, a configuration message, wherein the configuration message includes a parameter specifying out-of-order delivery of data units from lower layers to upper layers of a protocol stack implemented on the UE, configuring a radio link control (RLC) layer of a protocol stack for out-of-order delivery based on the received configuration message, and notifying the network entity of the configuration of the RLC layer.

Abstract: Apparatuses, systems, and methods for a wireless device avoiding reselection or handover to cells of different operators. The wireless device may attach to a first base station of a first network operator. The wireless device may determine that a neighboring base station is associated with a second network operator. Based on determining the neighboring base station is associated with the second network operator, the wireless device may exclude the third base station from handover or reselection.

Abstract: Apparatuses, systems, and methods for a wireless device to perform methods to implement mechanisms for non-stand-alone unlicensed band cells that support single carrier capable UEs. A UE may camp on a licensed band cell of a RAN and transmit a request to connect. The UE may receive, from the licensed band cell, a connection setup message indicating a switch to an unlicensed band cell of the RAN and receive, from the unlicensed band cell, a reference signal. The UE may transmit to the unlicensed band cell and in response to confirming, based at least in part of the reference signal, radio quality and/or downlink timing of the unlicensed band cell, a connection complete/connection resume message.
