Wireless communications may be used to support transmission power control. A message to schedule a transmission may be received without indicating a parameter for determining a power for the transmission. The transmission power may be determined based on a pathloss reference signal associated with a lowest index of a power control parameter set.

Power control for wireless communications

Wireless communications may be used to support data processing. A plurality of resources may be indicated for a wireless device to use to communicate and/or process data. Data may be received and processed based on groups of the plurality of resources to be used. For example, the plurality of resources to be used may be associated with different resource groups.

Communication and data processing in wireless communications

A wireless device receives downlink control information (DCI) comprising one or more fields set to one or more values. The wireless device validates, based on the one or more values, the DCI as an activation or a release of a configured grant of a bandwidth part (BWP) of BWPs of a cell. The wireless device transmits, based on validating the DCI, a confirmation of receiving the DCI, wherein the confirmation comprises an identifier of the BWP and an identifier of a sub-band of a plurality of sub-bands of the BWP.

Configured grant processes for wireless devices

A wireless device may receive, from a base station, one or more radio resource control (RRC) messages. The one or more RRC messages may indicate a plurality of demodulation reference signal (DMRS) patterns and a length of a DMRS for each of the plurality of DMRS patterns. The wireless device may determine a DMRS pattern of a physical sidelink shared channel (PSSCH) based on the plurality of DMRS patterns and the length of the DMRS in the DMRS pattern. The wireless device may transmit, to a second wireless device, sidelink control information (SCI) indicating the DMRS pattern of the PSSCH and a number of one or more antenna ports for the DMRS in the DMRS pattern.

Sidelink demodulation reference signal indication in sidelink control information

A wireless device receives radio resource control messages including a first bitmap, of frequency allocation of a search space (SS), with each bit indicating whether frequency resources of the SS are mapped to a respective resource block (RB) set of RB sets of a bandwidth part. Based on the first bitmap indicating that the SS is mapped to first RB sets of the RB sets, a physical downlink control channel (PDCCH) is monitored via the SS in the first RB sets. A first downlink control information is received that includes a second bitmap, of RB set indication, with each bit indicating whether a respective RB set, of the RB sets, is available for downlink reception. Based on the first bitmap and based on the second bitmap indicating a second RB set of the first RB sets as being available for downlink reception, the PDCCH is monitored via the SS in the second RB set.

Downlink control channel monitoring in new radio unlicensed band

Wireless communications may comprise communications between a base station and a wireless device. Wireless resources, such as bandwidth parts, may be used for the wireless communications. Based on a determination to switch a wireless resource, another wireless resource may be activated within a time duration. The time duration may be based on whether the wireless resource to be activated and the wireless device to be switched are in a same group of wireless resources.

Wireless resource switching

Wireless communications may be used to support data processing. Data processing may be performed based on a priority indication (or lack thereof) in a message for processing data. At least one parameter may be used to determine a priority associated with data processing if a message does not comprise a priority indication.

A first wireless device receives, from a base station, configuration parameters of a scheduling request for a sidelink buffer status report (BSR) of a sidelink between the first wireless device and a second wireless device. The scheduling request is triggered for the sidelink BSR in response to data becoming available for transmission to the second wireless device via the sidelink. The first wireless transmits, based on the triggering and to the base station, a preamble for a random access procedure to obtain a first uplink grant to transmit the sidelink B SR. The sidelink BSR is transmitted via a second uplink grant different from the first uplink grant indicated in a random access response corresponding to the preamble. The random access procedure is stopped in response to transmitting the sidelink BSR.

Sidelink channel state information report

A wireless device receives configuration parameters of channel state information (CSI) resource configurations for a CSI report configuration of a cell. The CSI resource configurations comprise first CSI resource configurations associated with a first transmission reception point (TRP) of the cell and second CSI resource configurations associated with at least two TRPs of the cell, wherein the at least two TRPs comprise the first TRP. The wireless device receives a command comprising a first field triggering the CSI report configuration of the cell and a second field indicating that the CSI report configuration is associated with the second CSI resource configurations. The wireless device transmits, based on the CSI report configuration and in response to the command, a CSI report comprising one or more CSI quantities of the at least two TRPs.

Channel state information reporting for non-coherent joint transmission

A wireless device receives configuration parameters comprising pathloss reference linking indicators for SRS resource sets of a first cell associated with one or more TRPs, wherein each SRS resource set of the SRS resource sets comprises SRS resources, and each SRS resource set is associated with a respective pathloss reference linking indicator of the pathloss reference linking indicators, indicating a cell index identifying a pathloss reference cell. The wireless device transmits, via SRS resources of a first SRS resource set of the SRS resource sets in the first cell, SRSs with a transmission power determined based on a first pathloss RS of a first pathloss reference cell, wherein the first pathloss reference cell is indicated by a first pathloss reference linking indicator, of the pathloss reference linking indicators, associated with the first SRS resource set.

Power control for multiple transmission reception points

A base station transmits, to a wireless device, configuration parameters indicating one or more first reference signals (RSs), on a first cell, as RSs for a beam failure recovery (BFR) procedure of a second cell. Based on a deactivation of the first cell, the base station stops transmitting a response for the BFR procedure of the second cell, wherein the BFR procedure is triggered by the wireless device for the second cell.

Beam failure recovery with multiple cells

A base station may transmit configuration parameters indicating a bandwidth part (BWP), of a cell, associated with a maximum number of transmission layers, and a plurality of demodulation reference signal (DMRS) ports. The base station may transmit downlink control information comprising an antenna port indication value. The base station may determine a subset of DMRS ports, from the plurality of DMRS ports, based on the maximum number of transmission layers associated with the BWP. Based on the antenna port indication value, the base station may select one or more DMRS ports from the subset of DMRS ports. The base station may transmit, via the BWP, a transport block with the one or more selected DMRS ports and with a number of transmission layers. The number may be less than or equal to the maximum number in response to the BWP being associated with the maximum number of transmission layers.

Antenna port determination based on maximum number of transmission layers of bandwidth part

Wireless resource determination and use are described. A wireless device may determine to use a resource (e.g., PUCCH resource), indicated by control information (e.g., DCI), for sending an acknowledgement (e.g., HARQ-ACK feedback) of a reception of data (e.g., at least one transport block). The control information may be received in a message of a plurality of messages. The wireless device may select the control information (e.g., for determining the resource) from among other control information in the plurality of messages, based on one or more factors.
