This disclosure provides systems, methods, and devices for wireless communication that support a shared transmission power control (TPC) for uplink data and control channels. In a first aspect, a method includes a user equipment (UE) receiving a TPC command in downlink control messages from a serving base station. Each TPC command includes a power correction indicator. The UE may then apply an accumulation of power correction indicators received in the downlink control messages to an adjustment state associated with a transmit power of an of uplink control channel and an uplink data channel. The UE transmits to an uplink receive point, the uplink control or data channel according to the transmit power adjusted by the accumulation of power correction indicators applied to the adjustment state. Other aspects and features are also claimed and described.

Disclosed is a method of a first wireless communication device configured for massive multi-user multiple-input multiple output (MU-MEMO) communication with two or more second wireless communication devices. The first wireless communication device comprises a plurality of antenna ports, each antenna port associated with at least one of a digital-to-analog converter (DAC) and an analog-to-digital converter (ADC). The method comprises acquiring an estimation of a communication channel between the first wireless communication device and the second wireless communication devices and acquiring an estimation of a quantization distortion caused by either DACs or ADCs. The method also comprises jointly determining (for the two or more second wireless communication devices) a transmission power and a transmission resource for each of the second wireless communication devices, wherein the joint determination is based on the estimation of the communication channel and on the estimation of the quantization distortion. Corresponding apparatus, network node and computer program product are also disclosed.

A user equipment (UE) determines a transmission power for data transmission to a network. The UE determines a specific absorption rate (SAR) limit associated with the UE and determines a transmission power to be allocated to data transmissions based on one or more applications running on the UE and the SAR limit.

Presented herein are techniques for using mobile client density to compensate for variations in path loss between neighboring access points. In one example, a device (e.g., wireless controller) determines one or more mobile client density variation trends in a wireless network location and determines one or more neighbor message power variation trends between at least first and second access points within the wireless network location over a time period. The device generates one or more correlation bias factors using the mobile client density variation trends and the neighbor message power variation trends over the time period. The device determines a path loss between at least the first and second access points based on the correlation bias factor and data associated with neighbor messages sent between the first and second access points.

Disclosed is a technology for performing, in an electronic apparatus included in a central station, an uplink- or downlink-related operation by allocating a transmission power intensity based on a transmission and reception capability of a terrestrial terminal.

There is provided a transmission power control method for a terminal. In this method, when reception power is divided into at least two ranks at equal intervals, each of the at least two ranks has an allowable range having an identical size, a margin is set between a lower limit of the allowable range in an upper rank and an upper limit of the allowable range in a lower rank in the at least two ranks, and the allowable range is equal to or larger than the margin, the terminal adjusts transmission power of the first signal and the second signal by using a transmission power adjustment amount calculated by using reception power of the first signal and the second signal, a reception power difference between these signals, the at least two ranks, the allowable range, and the margin.

Methods, systems, and devices for wireless communications are described. Multiple component carriers may be configured for communications between communication devices, where uplink data channel resources may be scheduled on a component carrier of the component carriers. A communication device may report, over the uplink data channel resources to another communication device, a first report for available transmission power for uplink data transmissions over the component carrier and a second report associated with available transmission power for uplink control transmissions over a second component carrier. The other communication device may use the second report to determine the available transmission power for uplink control transmissions over the second component carrier. The other communication device may schedule communication resources based on the determined available transmission power for uplink control transmissions.

A method for allocating power of an electronic device, includes generating a power budget indicating an amount of available power for signal transmission and reception. The method also includes determining whether to prioritize communication signals or radar signals for allocating the available power of a battery. In response to a determination to prioritize the communication signals, the method includes allocating a first portion of the available power for the communication signals and a second portion of the of the available power for the radar signals. In response to a determination to prioritize the radar signals, the method includes allocating the first portion of the available power for the radar signals and the second portion of the of the available power for the communication signals. The method further includes transmitting the communication signals and the radar signals based on the allocation.
