Abstract: A base station may configure a user equipment (UE) to perform sounding reference signal (SRS) transmissions using an SRS resource set. The SRS resource set may be configured for two or more functions, e.g., functions such as codebook-based SRS transmission, non-codebook-based SRS transmission, antenna port switching, beam management, etc. By enabling the use of such dual function (or multi-function) SRS resource sets, the average data rate associated with configuration transmissions to the UE may be reduced.

Abstract: Apparatuses, systems, and methods for performing uplink transmissions during a dual active protocol stack handover. A wireless device may determine a propagation delay between the wireless device and each of a source cell and a target cell of a dual active protocol stack handover by the wireless device. The wireless device may provide an indication to the source cell of the propagation delay between the wireless device and the source cell, the propagation delay between the wireless device and the target cell, and a propagation delay difference handling capability of the wireless device. The cellular base station that provides the source cell may determine a time division multiplexing pattern for uplink communication for the wireless device during the dual active protocol stack handover based at least in part on the information provided by the wireless device.

Abstract: Apparatuses, systems, and methods for PDCCH enhancements for group-based paging indications. A user equipment device may be configured to receive, from a network, an indication of a paging occasion via a PG-RNTI and/or via at least 6 bits of a DCI. A value of the PG-RNTI may be associated with the paging occasion as well as a set of UEs, including the UE. The UE may be configured to monitor the paging occasion based on the value of the PG-RNTI and receive, during the paging occasion, a paging indication via at least six bits of a DCI, where each bit of the at least six bits may indicate a paging indication for a particular set of UEs and the particular set of UEs may be a subset of the set of UEs. The UE may also be configured to, in response to determining that the UE has a paging message, decode a corresponding PDSCH.

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: 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: 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: 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.

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: Apparatuses, systems, and methods for a wireless device to perform master cell group failure recovery in a dual connectivity cellular communication system. The wireless device may establish a first wireless link to a cellular network via a first cell group. The first cell group may be configured as a master cell group for the wireless device. The wireless device may establish a second wireless link to the cellular network via a second cell group. The second cell group may be configured as a secondary cell group for the wireless device. The wireless device may determine that link failure for the first wireless link has occurred. The wireless device may perform master cell group link failure recovery using the second wireless link based at least in part on the link failure for the first wireless link.
