Wireless communication devices have antennas, and the antennas have earth-orientations. The wireless devices exchange network signaling with a wireless access node over the antennas. Some of network signaling indicates Device-to-Device (D2D) communication times and frequencies. The wireless communication devices exchange device signaling with each other over the antennas using the D2D communication times and frequencies. Some of the device signaling indicates the earth orientations for the antennas. The wireless communication devices select a subset of the antennas based on the earth orientations. The wireless communication devices exchange user data with each other over the selected subset of antennas using the D2D communication times and frequencies.

A method for operating a user equipment with multi-beam communication capability includes performing measurements in accordance with received reference signals, and determining that at least one antenna panel is unused, wherein the determining is in accordance with the measurements, and based thereon, reporting an availability of the at least one antenna panel.

Embodiments of the present disclosure disclose a method for improving Wi-Fi performance and a terminal. The method includes: determining, by a terminal, whether a currently working Wi-Fi channel is interfered by an HDMI signal and whether strength of a received Wi-Fi signal is less than or equal to a preset signal strength threshold, where the terminal is configured with a Wi-Fi module and an HDMI port; and if the currently working Wi-Fi channel is interfered by the HDMI signal, and the strength of the received Wi-Fi signal is less than or equal to the preset signal strength threshold, controlling, by the terminal, a Wi-Fi antenna most greatly interfered by the HDMI signal to stop receiving/sending a signal. According to the embodiments of the present disclosure, interference from the HDMI signal to the Wi-Fi signal can be reduced, and Wi-Fi performance can be improved without increasing hardware complexity and hardware costs.

A battery-powered wireless communication device has internal antennas. In the wireless communication device, transceiver circuitry wirelessly receives external antenna data that indicates on/off status, reserve battery power, and geometric earth-orientation for the individual antennas in a different wireless communication device. Baseband circuitry determines internal antenna data that indicates the on/off status, reserve battery power, and geometric earth-orientation for the internal antennas. The baseband circuitry executes a user application that generates and consumes user data. The baseband circuitry selects a set of the internal antennas to serve the user application based on the internal antenna data and the external antenna data. The transceiver circuitry wirelessly exchanges the user data over the selected set of the internal antennas.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may estimate a throughput requirement associated with a communication between the UE and a network node. The UE may select a beam level, of multiple candidate beam levels capable of satisfying the throughput requirement, that is associated with a lowest power consumption. The UE may communicate with the network node using the beam level. Numerous other aspects are described.

In one embodiment, a method implemented in a WD includes one or more of: estimating an expected number of multiple-input multiple-output (MIMO) layers based at least in part on channel state information (CSI) and/or a sounding reference signal (SRS) configuration; determining a set of antennas of a plurality of antennas to use based at least in part on the estimated expected number of MIMO layers; and/or receiving a MIMO signal using the determined set of antennas. In one embodiment, a method implemented in a network node include receiving a channel state information (CSI) report from the WD; and/or scheduling and/or transmitting a downlink (DL) channel to the WD using a number of multiple-input multiple-output (MIMO) layers, the number of MIMO layers used based at least in part on the received CSI report.

An Audio/Video (A/V) transmitting device may include a Radio Frequency (RF) transmitting module configured to transmit a compressed RF packet to an RF receiving module of an A/V receiving device, the RF transmitting module including a plurality of transmitting antennas, and a processor configured to obtain radio performance between the RF transmitting module and the RF receiving module and, when the obtained radio performance satisfies a preset radio performance, sequentially turn off one or more transmitting antennas among the plurality of transmitting antennas.

Systems and methods providing antenna element feed path component management for facilitating millimeter wave communication are described. Embodiments can enable and provide mitigation of thermal, power consumption, and/or maximum permissible exposure issues with respect to millimeter wave communication, such as by 5.sup.th generation (5G) or new radio (NR) compliant user equipment. Accordingly, embodiments are configured to manage transceiver antenna element feed path components to mitigate thermal, power consumption, and/or MPE concerns. For example, a communication device configured in accordance with concepts herein may reduce or otherwise control temperatures of various components, device power consumption, and/or user exposure to millimeter wave energy, such as to improve user experience, avoid component failure, extend battery life, etc.

A method for adjusting an antenna module can be applied to a terminal and include: transmitting, to a base station, the sending capability information of at least one antenna module of the terminal and/or the receiving capability information of at least one antenna module of the terminal; and according to a control signaling transmitted by the base station, controlling at least one antenna module of the terminal to work or stop working. Transmission efficiency of the terminal can therefore be improved, or be maintained while saving the power consumption of the terminal.
