Abstract: A base station transmits, to a wireless device via a control resource set (CORESET) of a CORESET group of CORESET groups, a downlink control information (DCI) scheduling transmission of an uplink signal, wherein each of the CORESET groups corresponds to a respective sounding reference signal (SRS) resource set of SRS resource sets. The base station determines an SRS resource set, from the SRS resource sets, corresponding to the CORESET group comprising the CORESET. The base station receives the uplink signal based on an SRS resource in the SRS resource set.

Abstract: A wireless device may receive a message indicating that it is to switch cells, such as in a handover process, and the wireless device may take steps to switch cells. The time needed for making the switch can depend on, for example, the time it takes the wireless device to process that message, and different types of messages (e.g., messages at a media access control—MAC—layer) may be processed more quickly than others. A wireless device may quickly cancel a triggered power headroom report (PHR) procedure for an old cell, and trigger a PHR for a new cell, based on receiving such a message. The canceling and/or triggering may be performed even without resetting a MAC entity of the wireless device.

Abstract: A first wireless device receives, from a second wireless device, one or more first sidelink transmissions in one or more first consecutive time slots in a resource pool. The first wireless device determines, based on one or more second consecutive time slots for one or more second sidelink transmissions in the resource pool being overlapped with the one or more first consecutive time slots in time domain, to skip a listen-before-talk (LBT) based channel access procedure for the one or more second sidelink transmissions. The first wireless device transmits, based on the determining and in the one or more second consecutive time slots, the one or more second sidelink transmissions.

Abstract: A wireless device comprises one or more processors and memory storing instructions. When executed by the one or more processors, the instructions cause the wireless device to receive one or more configuration parameters, for a non-terrestrial network (NTN), indicating candidate timing advance (TA) values for a first cell of cells. The instructions cause the wireless device to transmit, via the first cell, a preamble using a TA value selected from the candidate TA values based on one or more measurement power values of reference signals of the cells.

Abstract: A network repository function (NRF) receives, from an access and mobility management function (AMF), a discovery request for an address of a session management function (SMF), the discovery request comprising network slice isolation information for at least one network slice. The NRF sends, to the AMF and based on the discovery request, a discovery response comprising the address of the SMF.

Abstract: Methods and apparatus are described for wireless communications involving transmission points. A transmission point may configure a downlink channel (e.g., a physical downlink control channel) based on the configuration of a downlink channel associated with another transmission point. One or more transmission points may manage overlap or offset between downlink channels.

Abstract: A wireless device receives one or more messages comprising configuration parameters for a cell group. The cell group comprises: a first secondary cell configured with one or more beam failure recovery (BFR) parameters; and one or more second cells configured to use the first secondary cell for a BFR procedure. A deactivation timer of the first secondary cell is restarted in response to receiving a physical downlink control channel indicating an uplink grant or a downlink assignment for any secondary cell, other than the first secondary cell, in the cell group.

Abstract: A wireless device receives parameters, including a first discontinuous reception (DRX) configuration associated with unicast transmissions in a cell and a second DRX configuration associated with multicast and broadcast services (MBS) in the cell. The wireless device may also receive a power saving (PS) indication indicating not to start a DRX on duration timer. The PS indication may be applied for the first DRX configuration; and it may not be applied for the second DRX configuration. The wireless device may further skip monitoring, in a first DRX on duration of the first DRX configuration, first physical downlink control channels (PDCCHs) for the unicast transmissions based on receiving the PS indication. The wireless device may also monitor, in a second DRX on duration of the second DRX configuration and while skipping monitoring the first PDCCHs in the first DRX on duration, second PDCCHs for the MBS.

Abstract: Control information may be used to schedule communications between a wireless device and a base station. The wireless device may monitor control channels associated with one or more cells to receive the control information.

Abstract: A second access point (AP) (e.g., slave AP) may transmit to a first AP (e.g., master AP) an indication as to whether it intends to transmit to multiple users during a multi-AP transmission. The first AP may assign the second AP its primary channel for the multi-AP transmission, for example, based on the indication from the second AP.

Abstract: An access point (AP) may communicate with one or more stations (STAs) (or wireless devices or computing devices). The AP may receive a first frame from a first station. The first frame may comprise a buffer status report (BSR) for a peer-to-peer (P2P) connection of the first STA with a second STA. The AP may send a second frame, where the second frame may indicate a first frequency allocation for use by the first STA and a second identifier of the second STA.

Abstract: A wireless device may receive a radio resource control (RRC) message that may include a handover indicator and a retain or release indicator. The handover indicator may indicate the target cell for a lower layer-based (e.g., L1/L2-based) handover of the wireless device. After the handover to the target cell, the wireless device may retain or remove/release stored candidate cells for future handovers based on the retain or release indicator.

Abstract: Systems, apparatuses, and methods are described for wireless communications. A base station may receive resource status information. The base station may use the resource status information for initiating a handover procedure using resource status information.

Abstract: A first wireless device receives, from a second wireless device, sidelink control information comprising a field with a value indicating to transmit a report message comprising preferred radio frequency resources of a sidelink between the first wireless device and the second wireless device. In response to the value of the field indicating to transmit the report message, the first wireless device transmits, to the second wireless device and via a physical sidelink shared channel of the sidelink, the report message indicating radio frequency resources preferred by the first wireless device. The first wireless device receives, from the second wireless device, sidelink transport blocks via one or more resources of the preferred radio frequency resources.

Abstract: A base station may communicate with a wireless device. A message may be used to indicate information for a layer 1 and/or layer 2 triggered mobility (LTM) procedure. For example, a medium access control (MAC) control element (CE) may indicate various information such as a target cell for the LTM procedure, whether to perform a random access (RA) procedure toward a target cell, a TA value, a bandwidth part (BWP) of BWPs of the target cell, and/or other information associated with the LTM procedure.

Abstract: A first wireless device receives, from a base station, one or more messages indicating a plurality of sidelink (SL) resource pools of an SL carrier and a channel busy ratio (CBR) threshold. The first wireless device, in response to a CBR of a SL resource pool being below or equal to the CBR threshold, selects, among the plurality of SL resource pools, the SL resource pool based on: an SL feedback transmission being disabled for an SL logical channel; and the SL resource pool comprising at least one physical sidelink feedback channel (PSFCH) resource. The first wireless device transmits, to a second wireless device via the SL resource pool, an SL data of the SL logical channel.
