Abstract: A wireless device and a base station may use configuration parameters, comprising transmission configuration indicator states, to communicate. A transmission configuration indicator codepoint, for application of one or more transmission configuration indicator states of each cell among a plurality of cells, may be indicated dynamically, for example, by downlink control information. A default rule may be applied to determine a transmission configuration state, among the one or more indicated transmission configuration states of a cell, to use for communication. A first (or last) listed transmission configuration state, a transmission configuration state having a lowest (or highest) index, and/or a transmission configuration indicator state indicated by a default parameter and/or a default procedure, among at least two transmission configuration states, for example, may be selected for use.

Abstract: A wireless device drops sounding reference signal (SRS) transmissions, in SRS resources linked for bandwidth aggregation, that conflict in time with a transmission or a reception scheduled by downlink control information (DCI). A time period between a last symbol of the DCI and a starting symbol of the SRS transmissions is equal to, or greater than, a number of symbols plus a guard period of the bandwidth aggregation.

Abstract: A communication device may use a channel access procedure to determine channel availability for signal transmission. The communication device may select a channel access procedure, among a plurality of channel access procedures, based on a beam indication from a base station and a transmission beam to be used for the signal transmission.

Abstract: One or more parameters may be used to configure wireless communications between a wireless device and a base station. Configuration parameters may indicate SRS resources for sounding reference signal (SRS) bandwidth aggregation of component carriers. A capability message may indicate wireless device transmission and/or reception capability for one or more bands during a guard period of SRS bandwidth aggregation. At least some component carriers may lack an uplink channel and downlink transmission may not be received during the guard period, for example, based on the capability message indicating simultaneous transmission and reception is not supported for one or more bands.

Abstract: A wireless device receives one or more radio resource control (RRC) messages comprising configuration parameters indicating a first set of reference signals (RSs) for a first beam failure detection of a primary cell, a second set of RSs for a second beam failure detection of the primary cell, and a scheduling request (SR) configuration for reporting a beam failure detected on the second set of RSs. The first set of RSs is associated with a first group index and the second set of RSs is associated with a second group index. Based on the second beam failure detection on the second set of RSs, the wireless device transmits, using the SR configuration, a physical uplink control channel (PUCCH) transmission with a recovery request associated with the second set of RSs.

Abstract: A wireless device can receive configuration parameters indicating a first timing advance group (TAG) for a cell and a second TAG for the cell. The first TAG may be a primary TAG (PTAG).

The wireless device may further transmit uplink signals via the cell.

Abstract: A wireless device receives, via at least one of one or more first monitoring occasions, a first downlink control information (DCI) scheduling an uplink shared channel transmission. The wireless device receives, via a second monitoring occasion of second monitoring occasions, a repetition of a second DCI indicating transmission of an acknowledgement feedback. The wireless device sets the acknowledgement feedback to a negative acknowledgement (NACK) value based on a start of the second monitoring occasions being after a start of the one or more first monitoring occasions. The wireless device transmits, in the uplink shared channel transmission, the acknowledgement feedback.

Abstract: A method for beam determination may include receiving, by a wireless device from a base station, configuration parameters indicating transmission configuration indication (TCI) state pools, wherein each TCI state pool, of the TCI state pools, comprises TCI states. The method may also include transmitting an indication of a TCI state pool from the TCI state pools.

Abstract: An example method includes receiving, by a wireless device, downlink control information (DCI). The DCI may schedule transport blocks (TBs) via physical downlink shared channels (PDSCHs) at a first slot and a second slot. The DCI may also indicate a first transmission configuration indicator (TCI) state for reception of the TBs. The method may also include receiving, based on a second TCI state, a first TB, of the TBs, at the first slot. The method may also include receiving, based on the first TCI state, the second TB, of the TBs, at the second slot in response to a time difference between the first slot and the second slot being larger than a time gap.

Abstract: Transmission repetition may be used in wireless communications. Control channel repetition may be used for scheduling communications between a base station and a wireless device. A time period between the control channel and the scheduled communications may be less than a threshold time period.

Abstract: A wireless device receives one or more configuration parameters indicating a time window for controlling a radio link failure indication based on a beam failure recovery procedure. A first failure of the beam failure recovery procedure is determined during the time window. The first failure is ignored by not causing a radio link failure in response to the first failure being during the time window. A second failure of the beam failure recovery procedure after the time window is determined. A radio link failure in response to the second failure is indicated.

The PHR is transmitted based on a parameter, indicating to report two power headroom values of the cell, being absent in the PHR configuration.

Abstract: Beam determination may be used in wireless communications, for example, in a beam failure recovery procedure. One or more parameters may be communicated and/or used to indicate an association between resources and a corresponding control resource set (CORESET) pool index of multiple CORESET pool indices. For each of the multiple CORESET pool indices, a reference signal associated with the CORESET pool index may be determined. Wireless communications may be performed by selecting a reference signal for each of the multiple CORESET pool indices, and resources associated with a corresponding CORESET pool index may be communicated based on the selected reference.
