Methods, systems, and devices for wireless communication are described. A user equipment (UE), operating in a serving cell, may adjust a transmit power of an uplink message when a neighboring cell is operating in an opposite direction (e.g., relative to the direction of communications in the serving cell) within a same or similar frequency band in a same time period. The UE may receive control signaling that indicates a first power control configuration to be used when the neighboring cell is operating in a same direction as the serving cell and a second power control configuration to be used when the neighboring cell is operating in a different direction from the serving cell. The UE may select the appropriate power control configuration based on the communications directions of the serving cell and the neighboring cell and may transmit the uplink message in accordance with the selected power control configuration.

A wireless device receives configuration parameters of: one or more first cells of a first cell type; and one or more second cells of a second cell type. A calculated total transmit power for a plurality of signals is determined. The plurality of signals comprise a first sounding reference signal (SRS) configured for transmission, during a time interval, via the one or more first cells; and a second SRS configured for transmission, during the time interval, via the one or more second cells. The wireless device drops a transmission of the first SRS or scales a transmission power of the first SRS, based on a SRS transmit power priority of the first SRS, when the calculated total transmit power exceeds a first value. The SRS transmit power priority is based on a cell type of the one or more first cells.

A user equipment that supports a first set of beams accumulates transmit power control (TPC) commands to generate an accumulated correction factor during communication between the user equipment and a base station that supports a second set of beams. The user equipment is configured to use a first subset of the first set of beams during the communication and the base station is configured to use a second subset of the second set of beams during the communication. The user equipment detects a change in the first subset or the second subset. The user equipment resets the accumulated correction factor in response to detecting the change. In some cases, the user equipment generates a plurality of correction factors for a corresponding plurality of closed-loop processes. The user equipment resets some or all of the plurality of correction factors in response to detecting the change.

Methods, systems, and devices for wireless communications are described that provide for power control for dual connectivity. A UE may identify a power control configuration that determines priorities for uplink transmissions over multiple component carriers and one or more base stations. The UE may identify a union of semi-static uplink or flexible transmissions between multiple component carriers employed by one cell group, such as a master cell group and a secondary cell group, and determine a configured power level for the cell group. The UE may then determine whether to transmit an uplink transmission on a cell of another cell group, based on the power control configuration and the configured power level.

Various embodiments provide a communication method, a communications apparatus, and a computer-readable storage medium. In those embodiments, a first transmit power can be determined for transmitting first information in a first time unit on a first carrier and a second transmit power can be determined for transmitting second information in a second time unit on a second carrier. A third transmit power can be determined for transmitting the second information in a first time period and transmitting the second information in a second time period using the second transmit power or the third transmit power. The second information can be sent in the first time period using the third transmit power. In those embodiments, a sum of powers used by a terminal device to transmit two uplink carriers in a same time period does not exceed a maximum transmit power of the terminal device.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether an uplink communication that is scheduled to be transmitted by a plurality of physical uplink repetitions in multiple slots on a plurality of beams is subject to a maximum permissible exposure (MPE) condition. The UE may determine a transmission adjustment for the plurality of physical uplink repetitions on the plurality of beams, based at least in part on a determination that the uplink communication is subject to the MPE condition, and transmit the uplink communication based at least in part on the transmission adjustment.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may establish a first wireless connection with a first wireless device, and a second wireless connection with the first wireless device or a second wireless device, where the first wireless connection and the second wireless connection operate in a dual connectivity mode. The UE may identify first and second energy efficiency metrics associated with the first and second wireless connections, respectively. The UE may identify one or more parameters associated with a transmit power of communications at the UE, and may compare the first energy efficiency metric and the second energy efficiency metric. The UE may then allocate a first power resource to the first wireless connection, a second power resource to the second wireless connection, or both, based on the comparison, the one or more parameters, or a combination thereof.

This disclosure provides methods, devices and systems for increasing the transmit power of wireless communication devices operating on power spectral density (PSD)-limited wireless channels. Some implementations more specifically relate to physical layer (PHY) convergence protocol (PLCP) protocol data unit (PPDU) designs that support distributed transmission. In some implementations, a PPDU may be generated based on one or more legacy tone plans. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones representing a logical RU, and the M tones may be further mapped to M noncontiguous subcarrier indices in accordance with a distributed tone plan. In some other implementations, a PPDU may be generated based on a distributed tone plan. In such implementations, a portion of the PPDU may be modulated on a number (M) of tones coinciding with M noncontiguous subcarrier indices in accordance with the distributed tone plan.

Disclosed is a power sharing method, including: determining a transmit power of a UE on a first carrier and a transmit power of the UE on a second carrier; and receiving first uplink traffic transmitted by the UE on the first carrier according to the transmit power on the first carrier, and receiving second uplink traffic transmitted by the UE on the second carrier according to the transmit power on the second carrier. Further disclosed are a power sharing apparatus, a storage medium, and a processor.
