Power control of sidelink operation
A wireless device receives one or more messages. The one or more messages comprise a sidelink priority for a sidelink transmission via a sidelink resource pool; a first priority threshold for the sidelink resource pool; and a second priority threshold for the sidelink resource pool. The sidelink transmission overlapping with a configured uplink transmission is transmitted based on comparing the sidelink priority with: the first priority threshold in response to the configured uplink transmission being a first priority class; and the second priority threshold in response to the configured uplink transmission being a second priority class.

Methods, systems, and devices for wireless communications are described. The method, system, or devices for wireless communications may implement receiving a grant for a first transmission scheduled for a first set of resources, the first transmission associated with a first transmission parameter; receiving an indication to cancel the first transmission; dropping the first transmission based on receiving the indication; determining a second transmission parameter for a second transmission based on the first transmission parameter and irrespective of dropping the first transmission; and performing or receiving the second transmission according to the second transmission parameter. Alternatively, a device may receive an indication to cancel the second transmission; drop the second transmission based on receiving the indication; and refraining from rescheduling the first transmission on the first set of resources based on receiving the indication and irrespective of dropping the second transmission.
Measurement gap configuration for multi-TRP antenna calibration
A base station may perform online calibration of antenna elements at two or more transmission reception points (TRPs) based on measurements by one or more user equipment (UEs).

REGULATORY LIMIT COMPLIANT PACKET PRIORITY-BASED ADAPTIVE TRANSMIT POWER CONTROLLER
A wireless device includes one or more antennas coupled to a transmit (TX) chain. The TX chain is configured to generate output RF signals using baseband signals. The TX chain includes a TX power controller configured to classify a packet of the output RF signals into a priority category of a plurality of priority categories based on priority information within the packet. The TX power controller is further to determine a time average specific absorption rate (TAS) energy budget of the wireless device. The TAS energy budget is based on a pre-configured regulatory power limit (e.g., SAR transmit power limit) of the wireless device over a time interval. Transmission power for transmitting the packet is determined based on the priority category and the TAS energy budget. The packet is encoded for transmission via the one or more antennas using the determined transmission power.
TECHNIQUES FOR MANAGING EXPOSURE USING UPLINK DUTY CYCLING
Methods, systems, and devices for wireless communications are described for radio frequency (RF) exposure limit compliance using uplink duty cycling. A user equipment (UE) may transmit a buffer status report (BSR) that indicates an amount of data that is to be transmitted by the UE, where lower priority data reported in the BSR may be throttled in order to reduce an amount of uplink resources associated with the lower priority data and thereby adjust an uplink duty cycle of the UE. The reduced uplink duty cycle may provide for additional transmit power that is available for higher priority data transmissions.

The disclosed method and an apparatus are directed to determine an uplink transmission power in in New Radio (NR) systems by a wireless transmit/receive unit (WTRU) for transmitting at least one physical uplink shared channel (PUSCH), using multiple beams toward multiple Tx/Rx points (TRPs). The method includes determining common parameters like a target receive power, a modulation and coding scheme (MCS) specific offset, and a transmit power control (TPC) command parameters common to the multiple beams. The method also includes determining beam-specific parameters like path loss for each beam, a configurable fractional power compensation factor for each beam, and a configurable maximum transmit power level of the each beam, wherein the fractional power compensation factor and the configurable maximum transmit power level for the each beam are determined dynamically or semi-statically based on at least deployment, WTRU mobility, or interference level.
