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

A wireless device may receive an activation command comprising a set of at least two transmission configuration indicator (TCI) states for a control resource set (coreset) with a lowest coreset index in an active downlink bandwidth part of a cell. The wireless device may also receive downlink control information (DCI) scheduling a downlink signal. The wireless device may select a TCI state that occurs first in the set of the at least two activated TCI states of the coreset, based on a time offset between the DCI and the downlink signal being less than a threshold. In response, the wireless device may receive a downlink signal based on the selected TCI state.

Downlink signal reception in control channel repetition

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

A wireless device may receive one or more configuration parameters indicating entries of a time domain resource allocation table and one or more scheduling offsets. Each entry of the entries may comprise a respective slot offset. The wireless device may receive downlink control information (DCI) indicating a first entry of the entries and a first scheduling offset of the one or more scheduling offsets. The wireless device may receive downlink data in a first slot determined based on a slot offset of the first entry and the first scheduling offset.

High frequency time domain resource allocation

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 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

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 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 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.

Determination of spatial filter for transmissions

A wireless device may receive a physical downlink control channel (PDCCH) with first downlink control information (DCI) scheduling an uplink transmission. The wireless device may receive, via at least one PDCCH monitoring occasion of PDCCH monitoring occasions, a repetition of second DCI that indicates cancelation of one or more symbols of the uplink transmission. The wireless device may cancel the one or more symbols of the uplink transmission based on a last symbol of the PDCCH reception with the first DCI being earlier than a starting symbol of the PDCCH monitoring occasions.

Interrupted transmission in control channel repetition

Control channel repetition may be used in wireless communications. A base station may send repeated downlink control information (DCI) or physical downlink control channel (PDCCH) to a wireless device. The base station may send configuration parameters to the wireless device to indicate a plurality of coresets and indicate whether a particular DCI field, such as a transmission configuration indicator (TCI) field, will be present in the repeated DCI. Wireless resources may be determined by the wireless device based on a candidate of the last configured repetition.

Control channel repetition using multiple coresets

A base station may transmit, to a wireless device, configuration parameters for semi-persistent scheduling (SPS), indicating periodic downlink resources for SPS physical downlink shared channel (PDSCH) transmissions. The base station may transmit, to the wireless device, a downlink control information (DCI). The DCI may indicate: an activation of the periodic downlink resources, a PUCCH resource for receiving feedback information corresponding to a plurality of SPS PDSCH transmissions via the periodic downlink resources, and a total downlink assignment index (DAI) incremented based on a number of the plurality of SPS PDSCH transmissions corresponding to the PUCCH resource. The base station may receive, from the wireless device via the PUCCH resource, feedback information bits for the plurality of SPS PDSCH transmissions based on the total DAI.

Semi-persistent scheduling in high frequency

A base station may transmit, to a wireless device, one or more messages indicating transmission configuration indicator (TCI) states for downlink transmissions. The base station may transmit, to the wireless device, a medium access control control element (MAC CE) activating a plurality of TCI states of the TCI states. The base station may transmit, to the wireless device based on a reference signal identified during a random access procedure and before receiving downlink control information (DCI) indicating a TCI state from the plurality of TCI states, one or more downlink signals.

Default beam for downlink signal transmissions

A wireless device receives configuration parameters of a first control resource set (coreset) associated with at least one common search space (CSS) set and a second coreset associated with at least one user equipment (UE)-specific search space (USS) set. The wireless device receives a first control command indicating first transmission configuration indicator (TCI) state for the first coreset and a second control command indicating a second TCI state for downlink channels or both uplink and downlink channels. In response to the first coreset being associated with at least one CSS set, the wireless device receives first physical downlink control channel (PDCCH) receptions via the first coreset based on the first TCI state. In response to the second coreset being associated with at least one USS set, the wireless device receives second PDCCH receptions via the second coreset based on the second TCI state.
