An electronic device include an antenna, a power amplifier and at least one processor configured to identify, transmit power of user data to be transmitted within a first slot in which uplink transmission is initiated; switch, based on identifying that the user data is transmitted based on a first SCS, supply voltage for dynamic range of the PA to a voltage value corresponding to the Tx power; switch, based on identifying that the user data is transmitted based on a second SCS greater than the first SCS, the supply voltage to the voltage value, within second duration in the second slot, the second duration in the second slot being before an initiation of the first slot; and transmit, using the PA, the user data with the Tx power within the first slot, to the base station.

A wireless communication method performed by a first apparatus includes acquiring a transmit opportunity (TXOP) to transmit or receive a first physical layer protocol data unit (PPDU), identifying a second apparatus for sharing the TXOP, permitting at least one of transmission and reception of a second PPDU to the second apparatus in the shared TXOP, and transmitting the first PPDU to at least one third apparatus in the shared TXOP or receiving the first PPDU from the at least one third apparatus.

A data transmission method may include a first control apparatus sending first indication information to a second control apparatus. The first indication information is used to indicate to measure link quality between the second control apparatus and at least one terminal device. The second control apparatus generates first data. The second control apparatus sends the first data to the at least one terminal device based on the first indication information. The first data measure the link quality between the second control apparatus and the at least one terminal device.

A method, system, computer readable storage medium, or apparatus provides for receiving a first message from a user equipment (UE), wherein the first message comprises an indication of one or more conditions, wherein the one or more conditions comprises an indication that the UE has a radio mode that comprises new radio (NR); determining a required idle period for long term evolution (LTE) for the UE; determining, based on the first message and the required idle period for LTE, a transmission time interval (TTI) for NR that corresponds to the required idle period for LTE; and sending, to the UE, a second message, wherein the second message comprises an indication of the TTI for NR.

A wireless device may receive one or more messages comprising one or more configuration parameters comprising a pathloss reference signal update parameter that enables an activation command to update pathloss reference signals of an uplink channel. Based on the one or more configuration parameters comprising the pathloss reference signal update parameter, the wireless device may determine, for a power headroom report, a pathloss reference signal mapped to a sounding reference signal resource indicator (SRI)-physical uplink shared channel (PUSCH) power control parameter set with an SRI-PUSCH power control parameter set index equal to zero. The wireless device may transmit the power headroom report computed based on a pathloss estimation of the pathloss reference signal.

Methods and systems for wireless communication are described. A computing device may receive data via a network. The computing device may modify one or more settings associated with a network based on the data.

A communication device includes a transmission unit and a notification unit. The transmission unit transmits a second signal (for example, an URLLC signal) that requires low latency severer than a first signal (for example, an eMBB signal). When the transmission unit transmits the second signal (for example, the URLLC signal), the notification unit notifies another communication device (interfering station) that transmits the first signal (for example, the eMBB signal) of a request signal containing information requesting suppression of transmission power of the first signal (for example, the eMBB signal). As a result, it is possible to satisfy a requirement of a communication mode requiring low latency.

A method for determining uplink power and scheduling information, a terminal and a network side device are provides. The method includes obtaining scheduling information of an uplink signal, wherein the scheduling information at least indicates related information of Q subbands, Q is a positive integer; determining a first power scaling coefficient according to the scheduling information; determining transmission power of the uplink signal according to the first power scaling coefficient.

A method for operating user equipment (UE) includes generating, by the UE, a transmit precoding matrix indicator (TPMI) list including one or more TPMIs selected from a set of available TPMIs stored at a base station (BS). Data indicative of the TPMI list is transmitted to the BS. An index of the TPMI list is transmitted to the BS. Downlink control information (DCI) is received from the BS including an indication of at least one TPMI from the TPMI list based on the index. Uplink data is transmitted to the BS on a physical uplink shared channel (PUSCH) using the at least one TPMI.

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling which indicates a resource block indicating a number of reference signal tones and data tones in an uplink transmission. In some cases, the UE may determine a first transmission power for the reference signal tones, and a second transmission power for the data tones that is different from the first transmission power. In some other cases, the UE may identify a frequency allocation for the resource block which allocates a same frequency bandwidth for the reference signal tones and the data tones, and the UE may determine a same transmission power for the reference signal tones and the data tones based on the frequency allocation. Based on the determination of transmission powers, the UE may transmit the reference signal tones and the data tones to a base station.
