A user equipment (UE), such as a mobile phone, may support multiple power classes. Power classes can define maximum output power levels for uplink transmissions. A base station of a radio access network (RAN) can, based on metrics reported by the UE, dynamically instruct the UE to switch to using a different power class. For example, the base station may instruct the UE to switch from using a first power class with a higher maximum output power to using a second power class with a lower maximum output power, in order to preserve battery life of the UE in situations in which the second power class provides sufficient output power for uplink transmissions to reach the base station.

A terminal includes a receiving unit that receives P-Max that is configuration information of maximum transmit power in a cell in Frequency Range 2 (FR2) among Frequency Range 1 (FR1) and the FR2; and a control unit that performs, when the P-Max of the cell in the FR2 is not supported, an operation of ignoring the P-Max of the cell in the FR2 or an operation of considering the cell in the FR2 as a barred cell.

Techniques and apparatus for beam selection in compliance with radio frequency (RF) exposure limits. A method that may be performed by a wireless device includes receiving, from another wireless device, a plurality of signals via a plurality of beams; measuring a received signal power for each of the beams, based on the received plurality of signals; determining a transmit power limit for each of the beams based at least in part on an RF exposure limit; determining an estimation of a signal quality at the other wireless device for each of the beams based at least in part the received signal powers and the transmit power limits; selecting one of the beams based on the estimations of the signal qualities for the beams; and transmitting a signal via the selected beam.

There is provided a UE for performing communication, the UE comprising: at least one transceiver; at least one processor configured to use CA based on two NR operating bands; and at least one computer memory operably connectable to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising: transmitting an uplink signal based on NR operating band n1 or n3; receiving a downlink signal based on the NR operating band n1 or n3.

A method for enabling communication of data relating to samples of electric measurements, the method being performed in an intelligent electronic device, IED, including a cellular radio module, the IED being configured to protect power system equipment. The method includes the steps of: detecting channel quality using the cellular radio module, the channel quality relating to a channel between the IED and a base station; transmitting packets using the cellular radio module, each packet including data relating to samples of electric measurements for protecting power system equipment; and increasing sample rate of the electric measurements when the channel quality is worse than a first threshold.

The apparatus determines an association between one or more transmission configuration indicators (TCIs) and one or more corresponding uplink power control (ULPC) configurations based on a control message, receives control information indicating a transmission configuration indicator (TCI) for a transmission on an uplink (UL) channel, and determines a transmission power for the transmission on the uplink (UL) channel based on an uplink power control (ULPC) configuration associated with the transmission configuration indicator (TCI).

In some embodiments, a method for mitigating interference in a channel having multiple users includes: transmitting, by a transmitter, a signal of interest (SOI) to a sequential interference cancellation (SIC) receiver at a transmit power; determining a packet drop rate as seen by the receiver; and decreasing the transmit power in response to determining the packet drop rate exceeds a predetermined maximum packet drop rate. The transmitter's coding rate and/or modulation level may also be lowered based on the decrease in transmit power.

In some embodiments, a method for mitigating interference in a channel having multiple users includes: receiving a plurality of signals from a plurality of antenna elements, the received signals comprised of one or more interfering signals and a signal of interest (SOI); for each of the one or more interfering signals, beamforming the received signals to enhance the interfering signal, generating an estimate of the interfering signal, and adjusting the estimated interfering signal to undo the effects of beamforming; and subtracting each of the estimated interfering signals from each of the received signals to generate a plurality of interference-mitigated received signals.

In some aspects, a transmission-adjusting wireless node may transmit a first communication via a sidelink channel. The transmission-adjusting wireless node may receive, from a feedback-reporting wireless node, transmission-specific information relating to at least one of a channel quality of the sidelink channel or a power level for the transmission-adjusting wireless node. The transmission-specific information may be based at least in part on the first communication. The transmission-adjusting wireless node may adjust, based at least in part on the transmission-specific information, a transmission property of the transmission-adjusting wireless node to obtain an adjusted transmission property. The transmission-adjusting wireless node may transmit a second communication via the sidelink channel using the adjusted transmission property. Numerous other aspects are provided.
