A wireless device receives one or more messages indicating a first transmission occasion for a physical uplink control channel (PUCCH) resource and indicating a second transmission occasion for the PUCCH resource. The wireless device receives downlink control information (DCI) indicating a transmission configuration indicator (TCI) state and indicating the PUCCH resource. The wireless device skips transmission, via the first transmission occasion of the PUCCH resource and based on a first listen before talk (LBT) procedure indicating a busy channel on the first transmission occasion, of an acknowledgment of the receiving the DCI indicating the TCI state. The wireless device transmits, based on a second LBT procedure indicating an idle channel on the second transmission occasion, the acknowledgment via the second transmission occasion of the PUCCH resource.

Beam management procedures with shared spectrums

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

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 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 method for uplink control multiplexing of a physical uplink control channel (PUCCH) repetition may include transmitting, by a base station to a wireless device, a first message indicating PUCCHs for repetitions of uplink control information (UCI). The method may also include transmitting, by the base station, a second message indicating a number of repetitions of a transport block via physical uplink shared channels (PUSCHs) and indicating a beta offset for multiplexing the UCI via a PUSCH of the PUSCHs. The method may further include receiving, based on a coding rate that has been determined, based on the beta offset and the number of repetitions, and in response to the PUCCHs overlapping with the PUSCHs in at least one symbol, the UCI and the transport block multiplexed in the PUSCHs.

Uplink control multiplexing of a PUCCH repetition

A wireless device may receive downlink control information (DCI) indicating a first TCI state of TCI states. The first TCI state may be associated with a first power control parameter and may be applicable after a first time instance for uplink channel transmissions. The DCI may comprise an uplink grant scheduling a transport block at a second time instance and indicating a second power control parameter. The wireless device may select, from the first power control parameter and the second power control parameter, a power control parameter based on a comparison of the first time instance with the second time instance. The wireless device may determine, based on the selecting, a transmit power. The wireless device may transmit, based on the transmit power and via a physical uplink shared channel, the transport block.

Power control procedures with common beams

Downlink signals, such as synchronization signals and/or reference signals, may be used for facilitating communications between communication devices. The downlink signals may be dynamically reconfigured, for reduced resource consumption, using control channel signaling with reduced resource overhead. Reconfiguration of downlink signals may be based on determined traffic volume in the communication network to minimize any impact of the reconfiguration on network performance.

Dynamic signaling for energy saving in wireless communications

A wireless device receives a radio resource control message comprising a first sounding reference signal (SRS) resource set identifier of a first SRS resource set of a serving cell and a second SRS resource set identifier of a second SRS resource set of the serving cell. The wireless device transmits a power headroom report (PHR) medium access control control element (MAC CE) comprising a first field indicating a first power headroom value associated with the first SRS resource set and a second field indicating a second power headroom value associated with the second SRS resource set. The order of the first field and the second field in the PHR MAC CE is based on an ascending order of the first SRS resource set identifier and the second SRS resource set identifier.

Power headroom report for multiple sounding reference signal resource sets

A method may include receiving, by a wireless device and during a random access procedure, a random access response indicating a first backoff time interval of a first sub-band of a cell, and indicating a second backoff time interval of a second sub-band of the cell. The method may include selecting, for a preamble retransmission of the random access procedure, a backoff time interval based on the first backoff time interval and the second backoff time interval. The method may include performing, at a time based on the backoff time interval, a listen-before-talk procedure.

Random access backoff indicator

A wireless device receives one or more configuration parameters indicating a plurality of transmission configuration indicator (TCI) states for uplink transmissions. The wireless device transmits, for a random access procedure, a physical uplink shared channel (PUSCH) transmission with a spatial filter. The wireless device receives a medium access control control element (MAC CE) indicating activation of more than one TCI state of the plurality of TCI states. The wireless device transmits, with the spatial filter used during the random access procedure, one or more uplink signals before receiving a downlink control information (DCI) indicating a TCI state from the more than one TCI state.

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 base station may transmit to a wireless device one or more configuration parameters. The one or more configuration parameters indicate: one or more physical uplink control channel (PUCCH) resources, and a default beam is used for physical uplink shared channel (PUSCH) transmissions. The bases station may transmit to the wireless device downlink control information (DCI), with DCI format 0_0, scheduling a PUSCH. The base station may receive from the wireless device, via the PUSCH, a transport block according to a default spatial relation in response to: a DCI format of the DCI being the DCI format 0_0, the configuration parameters indicating that the default beam is used, each PUCCH resource of the one or more PUCCH resources not being configured with a spatial relation, and the wireless device being in a radio resource control (RRC) connected mode.
