At least one parameter may be used to determine a priority associated with data processing if a message does not comprise a priority indication.

Abstract: A wireless device may communicate with one or more other wireless devices. The wireless device-to-wireless device communication may use consecutive resources, such as in a multiple consecutive slot transmission. Consecutive resources may be assigned a same priority value and/or a same resource interval and data transmitted in the consecutive resources may be associated with the same priority value and/or the same resource interval.

One or more configuration parameters may be used to indicate whether to perform a reset and/or recovery procedure.

Abstract: A base station determines that a first reference signal configured for a beam failure detection overlaps in at least one symbol with a second reference signal. Based on the first reference signal and the second reference signal not being quasi co-located, the base station transmits one of the first reference signal and the second reference signal, and drops transmission of one of the first reference signal and the second reference signal.

Abstract: A wireless device may receive one or more messages comprising a parameter indicating that a first cell is cross-carrier scheduled by a second cell. The wireless device may monitor, on a first bandwidth part (BWP) of the second cell, a first physical downlink control channel (PDCCH) for cross-carrier scheduling the first cell. The wireless device may receive downlink control information (DCI) indicating a second BWP of the second cell as an active BWP. Based on the second BWP of the second cell being the active BWP, the wireless device may stop monitoring the first PDCCH for cross-carrier scheduling the first cell. The wireless device may monitor, on the first cell, a second PDCCH for self-scheduling the first cell.

Abstract: A wireless device determines, among an uplink transmission with a first priority and a sidelink transmission with a second priority, to transmit the sidelink transmission based on the second priority being higher than the first priority. The wireless device transmits the uplink transmission based on determining to transmit the sidelink transmission and a failure of a listen-before-talk (LBT) procedure associated with the sidelink transmission.

Abstract: Base stations and wireless devices may use cross-slot scheduling for each of a plurality of cells. Base stations and wireless devices may communicate regarding the cross-slot scheduling, including for example, one or more indications associated with cross-slot scheduling for one or more cells. A wireless device may determine cross-slot scheduling for one or more transmissions associated with the one or more cells. The wireless device may save power by switching to a power saving mode for at least one cell during one or more slots, based on the cross-slot scheduling.

Abstract: A method may include receiving, by a wireless device, a first downlink control information (DCI) indicating an uplink grant or a downlink assignment of a bandwidth part (BWP) of a cell. The method may also include starting, based on the first DCI, a BWP inactivity timer of the cell. The method may further include receiving a second DCI comprising a dormancy indication of the cell. Based on the second DCI, the method may include the wireless device stopping the BWP inactivity timer of the cell, as well as transmitting channel state information reports for a second BWP of the cell.

Abstract: A wireless device receives a downlink control information (DCI) comprising a field indicating a slot format indication (SFI) for a slot. The SFI indicates at least one random access symbol. The wireless device determines radio resources of one or more random access channel (RACH) occasions (ROs) of the slot based on the at least one random access symbol. The wireless device transmits a preamble via the radio resources of the one or more ROs.

Abstract: A base station may transmit a report mask indicating a transmission of a layer 1 reference signal received power (L1-RSRP) report limited to a time period when a discontinuous reception (DRX) timer is running for a wireless device. The base station may receive the L1-RSRP from the wireless device at a first time, in response to the DRX timer running at a predefined time period before the first time. The received L1-RSRP report may include an L1-RSRP value and a reference signal index associated with the L1-RSRP value. At second time, the base station may skip a reception of a configured L1-RSRP report transmission from the wireless device in response to the DRX timer not running at the predefined time period before the second time and the report mask.

The control information may comprise one or more indications of wireless resources to be used by the wireless device to receive the data. The wireless device may receive the data based on one or more determinations/conditions, such as satisfying a time offset (e.g., between reception of the downlink information and a scheduled transmission of the data), whether a control resource set is configured to indicate a transmission configuration state, and/or whether the control information indicates a transmission configuration state.
