Wireless communications are described. A wireless device may determine a first transmission power for a first signal and a second transmission power for a second signal. The wireless device may reduce signal transmission power of one or more of the first signal or the second signal, based on a calculated power value exceeding an allowable transmission power. The wireless device may reduce the signal transmission power during an overlap period or a non-overlap period, based on a duration of an overlap of the first signal with the second signal.

A resource configuration method includes: receiving power indication information reported by user equipment; and configuring, for the user equipment, a coverage compensation resource used when performing data transmission on the basis of a target maximum power level according to the target maximum power level indicated by the power indication information.

A method for uplink data transmission. The method is applicable to user equipment (UE), and includes: reporting maximum allowed power reduction (P-MPR) information to a base station, wherein the P-MPR information is used to indicate a maximum power reduction supported by the UE in a current communication frequency band; receiving scheduling information returned by the base station based on the P-MPR information; and transmitting uplink data according to the scheduling information.

This application provides a communication method in a dual-connectivity mode. In the communication method, maximum transmit power used by a terminal device to send a message corresponding to a main network protocol in a semi-persistent power sharing mode is maximum transmit power 2, maximum transmit power used by the terminal device to send a message corresponding to a secondary network protocol is maximum transmit power 3, the maximum transmit power 2 is less than theoretical maximum transmit power corresponding to the main network protocol, and the maximum transmit power 3 is greater than the theoretical maximum transmit power corresponding to the main network protocol.

Aspects described herein relate to detecting maximum permissible exposure (MPE) events and/or reporting the MPE event, related metrics, associated requests for beam switching or new time division duplexing (TDD) patterns, etc. In an aspect, a MPE event can be detected on at least one component carrier (CC) of multiple CCs configured with a first cell in inter-band carrier aggregation (CA), and one of a MPE report or a beam switching request can be transmitted to a second cell on a different CC of the multiple CCs. In another aspect, the cell can detect the MPE and can transmit, to the device, a beam switching command to switch to a new beam for uplink communications. In another aspect, the cell can transmitting, to another cell having another CC of the multiple CCs configured with the device, an indication to perform beam switching for the device.

An access point (AP) communicates to one or more stations (STAs) information indicating a set of channels and/or resource units (RUs), corresponding to a wideband basis service set (BSS) for an authorized unlicensed radio local area network (RLAN) using 6 GHz spectrum, which are subject to a lower power spectral density (PSD) level than other portions of the BSS frequency range or are not to be used for transmission. In some, but not necessarily all, embodiments, the AP and the STAs do not encode data on the identified channels or RUs, but do encode data on other channels and/or other RUs, which are not subject to the lower PSD constraint.

A method by a user equipment (UE) for transmitting one or more power headroom reports (PHRs) is provided. The method includes receiving, from a base station (BS), a Radio Resource Control (RRC) configuration comprising a first RRC parameter that indicates a first operation mode of multiple PHRs for multiple transmission reception points (TRPs); and transmitting, to the BS, a PHR medium access control control element comprising a first power headroom (PH) associated with a first TRP and a second PH associated with a second TRP. The first TRP and the second TRP are associated with a serving cell of the BS. The first PH is a first Type-1 PH associated with first physical uplink shared channel (PUSCH) transmission toward the first TRP. The second PH is a second Type-1 PH associated with second PUSCH transmission toward the second TRP. The UE is configured with multi-TRP based PUSCH repetitions.

The disclosure relates to a 5G or 6G communication system for supporting a higher data transmission rate. A method performed by a terminal is provided, the method including receiving, from a base station, a radio resource control (RRC) message including information associated with a power headroom report (PHR) of multiple transmission and reception points (TRPs), in case that a PHR is triggered, obtaining a first power headroom (PH) of a first TRP and a second PH of a second TRP, generating a medium access control (MAC) control element (CE) for the multiple TRPs including the first PH of the first TRP and the second PH of the second TRP, and transmitting, to the base station, the MAC CE for the multiple TRPs.

An electronic device may include: at least one communication processor, an RFIC, at least one power amplifier , and at least one converter and wherein the at least one communication processor is configured to: set a driving voltage, to be applied to a first power amplifier for amplifying a first RF signal provided from the RFIC among the at least one power amplifier, to be a first voltage, based on an APT mode, control at least part of the at least one converter to provide a first voltage, set based on the APT mode, to the first power amplifier during a transmission period of the first RF signal, and control at least part of the at least one converter to provide the first voltage to the first power amplifier during at least partial period of a remaining period in which no RF signal is transmitted, based on the occurrence of an event associated with audible noise.

Embodiments of this disclosure relate to the communications field, and provide a repeated transmission method and an apparatus, to increase a probability of successful decoding of a user equipment. The method includes: performing, by a user equipment, first transmission of uplink data, and sending a first reference signal to a network device based on a first transmit power, where the first reference signal is used to demodulate the first transmission of the uplink data; and performing, by the user equipment, N.sup.th transmission of the uplink data, and sending a second reference signal to the network device based on a second transmit power, where N is an integer greater than or equal to 2, the second reference signal is used to demodulate the N.sup.th transmission of the uplink data, and the second transmit power is less than the first transmit power.
