A wireless device receives a radio resource control (RRC) message indicating a first resource pool of a sidelink (SL) communication. The wireless device determines, from a candidate resource set in the first resource pool, a SL grant indicating resources for one or more SL transmissions of the SL communication. The wireless device receives, by a medium access control (MAC) layer from a physical layer of the wireless device, an indication of SL listen before talk (LBT) failure of a first resource of the resources indicated in the SL grant. Based on the indication, the wireless device selects, for the first resource, a second resource from the first resource pool excluding resources associated with SL LBT failure. The wireless device transmits, via the second resource, the one or more SL transmissions of the SL communication.

Slidelink transmission method and apparatus based on sidelink listen-before-talk failure on a shared spectrum

A wireless device may receive a first downlink control information (DCI) associated with scheduling resources for a transport block (TB) and indicating a first transmission configuration indicator (TCI) state from a first TCI state pool. The wireless device may further receive a second DCI indicating a second TCI state from a second TCI state pool. Based on the first TCI state being from the first TCI state pool and the second TCI state being from the second TCI state pool that is different from the first TCI state pool, the wireless device may receive the TB via the resources and based on the second TCI state.

Transmission and reception with multiple beams

Wireless communication techniques for power saving are described. A wireless device may be configured with one or more power saving configurations, such as a dormant state. During a dormant state, downlink channel monitoring (e.g., on a secondary cell) may be stopped and/or a beam failure recovery procedure may be performed.

Beam failure recovery in a power saving operation

A wireless device determines uplink precoders for a transmission of a transport block. The transmission of the transport block take place via uplink resources comprising sub-bands. The uplink precoders for each respective sub-band of the sub-bands are based on a transmission precoder of one or more sounding reference signal (SRS) resources transmitted via each of the respective sub-bands.

Coverage enhancement with frequency selective transmission

Wireless communications are described. A wireless device and/or a base station may determine/select one or more beams for transmission of signals (e.g., sounding reference signals, SRSs) in one or more cells. The wireless device and/or the base station may determine/select a beam based on one or more of: cell indicators of a first cell and/or a second cell, antenna panel indicators associated with SRS transmissions, priorities of SRS transmissions, resource set indicators corresponding to the SRS transmissions, and/or other information.

Methods, devices, and apparatuses for beam management

Wireless devices may communicate via a plurality of transmission and/or reception beams. Control information may be used to indicate one or more beams to be used by wireless devices. A configuration message may indicate a portion of the control information corresponding to a particular wireless device of the wireless devices.

Resource configuration for wireless communication

Wireless communication techniques using search space sets are described. A downlink channel may be monitored using search space sets based on one or more conditions. For example, a downlink channel may be monitored on a first search space set during a first time period (e.g., before an expiration of a timer) and/or a downlink channel may be monitored on a second search space set during a second time period (e.g., after an expiration of a timer).

Downlink monitoring using search space sets

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.

Scheduling wireless communications

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.
