Methods, apparatus, and systems for wireless communications are disclosed. A first base station may receive one or more message from a second base station. The messages may include downlink beamforming information elements for a downlink cell. Each downlink beamforming information element may be associated with a respective group of resource blocks of a plurality of groups of resource blocks in the downlink cell. The first base station may select a first beamforming codeword for at least one group of resource blocks of the plurality of groups of resource blocks based on the downlink beamforming information associated with the at least one group of resource blocks. The first base station may transmit, to a wireless device, signals on the at least one group of resource blocks employing the first beamforming codeword.

Beamforming in wireless communications

A first base station receives a first request to notify a change of a closed access group (CAG) area of a wireless device. The first base station sends, to an access and mobility management function (AMF), a location report message indicating the change of the CAG area of the wireless device.

Location reporting handling

A wireless device may receive one or more configuration parameters indicating a single frequency network (SFN) scheme. The wireless device may further receive a command activating at least two transmission configuration indicator (TCI) states for a control resource set (coreset). The wireless device may monitor, via the coreset, downlink control channels based on the at least two active TCI states and determine a radio link quality based on the at least two active TCI states of the coreset, when the one or more configuration parameters indicate the SFN scheme. The wireless device may further transmit an uplink signal indicating the radio failure, when the radio link quality indicates a radio failure.

Radio link monitoring based on active TCI states

A wireless device may receive from a base station a first downlink control information (DCI) scheduling a physical downlink shared channel (PDSCH) transmission. The first DCI may indicate that the wireless device is not to transmit feedback for the PDSCH transmission before receiving a second DCI and a PDSCH group index. The second DCI may indicate a time slot for transmitting feedback and the PDSCH group index. In response to the wireless device receiving the second DCI and based on the second DCI indicating feedback for the same PDSCH group index as the first DCI, the wireless may transmit to the base station, in the time slot indicated, the feedback for the PDSCH transmission.

Scheduling physical downlink shared channel feedback

A second base station transmits a message to a first base station. Based on the second base station having a backhaul interface to a third base station, the message includes parameters of one or more cells of the third base station. The second base station transmits, to the first base station, a request to add the first base station as a secondary base station. The second base station receives, from the first base station and based on the message, a request of a change of the secondary base station from the first base station to the third base station.

Adding of a secondary base station based on a backhaul interface

The current block may be predicted using a reference block and a difference between templates of the current bock and the reference block. The reference block may be selected from a plurality of candidate reference blocks. The selection may be based on a template matching cost that indicates the differences between the templates of the current block and the templates of a respective candidate reference block. An encoder or a decoder may transform samples from templates of the current block and of the candidate reference block into the same domain, for example, if the samples are in different domains before determining the template matching cost.

Luma mapping for template matching

A wireless device receives, from a base station, one or more radio resource control (RRC) messages comprising a unified transmission configuration indicator (TCI) state type parameter, for a cell, that indicates a unified TCI state type among a separate TCI state type and a joint TCI state type. The separate TCI state type indicates one or more first TCI states are for downlink receptions via the cell and one or more second TCI states are for uplink transmissions via the cell. The joint TCI state type indicates one or more third TCI states are for both the downlink receptions and the uplink transmissions via the cell. The wireless device communicates, with the base station and via the cell, based on the unified TCI state type.

Transmission configuration indicator configuration

Methods, apparatuses, and systems are described for wireless communications. Cells may be grouped into a plurality of cell groups. A wireless device may transmit or drop one or more of a plurality of signals.

Transmit power control in multicarrier communications

A wireless device receives one or more messages comprising a parameter indicating a first value of a listen before talk (LBT) counter. The LBT counter is incremented based on an LBT procedure indicating an LBT failure for an uplink transmission via a first bandwidth part. Based on the LBT counter reaching the first value, a switch is made from the first bandwidth part to a second bandwidth part as an active bandwidth part.

Cell and bandwidth part operations in unlicensed bands

A wireless device may receive at least one radio resource control (RRC) message comprising a field indicating a starting symbol for an enhanced physical downlink control channel (ePDCCH). The wireless device may receive an ePDCCH signal. The ePDCCH may start from the starting symbol plus an offset value.

Control channel configuration

Wireless communications may use one or more devices for transmission and/or reception that may lead to potentially harmful exposure. One or more safety measures may be used for wireless communication devices, such as maximum power exposure (MPE) reporting and/or related operations. An MPE report may be sent based on MPE detection and one or more messages, such as for cell activation, bandwidth part (BWP) or other wireless resource activation and/or switching, and/or a discontinuous reception (DRX) or other state transition.

Exposure reporting for wireless communications

A wireless device may receive a first message indicating a first transmission configuration indicator (TCI) state for receiving a downlink control channel. After receiving the first message, the wireless device may receive a second message indicating a common TCI state for receiving the downlink control channel and a downlink shared channel. Based on an end of a first application time of the first TCI state being later than an end of a second application time of the common TCI state, the wireless device may receive the downlink control channel using the first TCI state.

Reception of channel based on time for applying transmission configuration indictor state

A wireless device receives one or more messages indicating transmission resource pools of a sidelink, where the transmission resource pools comprise a first transmission resource pool and a second transmission resource pool. In some cases, the wireless device is allowed to use the second transmission resource pool based on one or more thresholds associated with sidelink transport blocks. Based on a transport block meeting the one or more thresholds, the wireless device selects one or more sidelink resources from the second transmission resource pool. The wireless device transmits the transport block via the one or more sidelink resources.

Sidelink resource pool selection for urgent packet transmission

A destination wireless device receives, from a base station, configuration parameters of physical sidelink feedback channel (PSFCH) radio resources. The destination wireless device receives, from a source wireless device, sidelink control information comprising an identity (ID) of the source wireless device. The destination wireless device transmits, to the source wireless device, an acknowledgement for a transport block via a PSFCH radio resource having an index. The index is based on: the ID of the source wireless device, an ID of the destination wireless device, and a modulo operation performed on a quantity of the PSFCH radio resources.

Feedback resource

A first base station determines that session resources for a network slice are not available for a wireless device. The first base station sends to a second base station and based on the determination, a request for a handover of the wireless device. The request comprises: an identifier of the network slice for the handover; and a cause information element indicating that a cause for the handover is that the session resources are not available for the network slice at the first base station. A response to the request is received from the second base station.
