Transmission quality is improved in an environment in which direct waves dominate in a transmission method for transmitting a plurality of modulated signals from a plurality of antennas at the same time. All data symbols used in data transmission of a modulated signal are precoded by hopping between precoding matrices so that the precoding matrix used to precode each data symbol and the precoding matrices used to precode data symbols that are adjacent to the data symbol in the frequency domain and the time domain all differ. A modulated signal with such data symbols arranged therein is transmitted.

Some demonstrative embodiments include apparatuses, devices, systems and methods of communicating an Enhanced Directional Multi-Gigabit (DMG) (EDMG) Physical Layer Protocol Data Unit (PPDU). For example, an EDMG wireless communication station (STA) may be configured to communicate an EDMG PPDU including a Channel Estimation Field (CEF) and/or a pilot sequence, which may be configured for an OFDM mode.

Systems and methods for improving power efficiency of electronic systems are disclosed. An intelligent voltage regulator module (VRM) can self-regulate the output power provided to one or more components of an electronic system. For example, output voltage to a component can be increased when more computational power is needed or lowered when appropriate. The intelligent VRM can regulate the output power, for instance, based on one or more of usage or activity of the component. In some cases, the intelligent VRM can independently regulate the output power without input from a host device or override one or more output power parameters. Adjustment of the output power can be performed using machine learning (ML).

A method by which a terminal transmits an SRS can comprise the steps of: receiving, from a base station, first information indicating symbols to which the SRS is transmitted among a plurality of symbols, when the terminal is configured to perform antenna switching for an SRS transmission on the plurality of symbols; and transmitting the SRS on the indicated symbols, wherein the SRS is transmitted through antenna ports respectively corresponding to the indicated symbols, and the antenna ports respectively corresponding to the indicated symbols can be different from each other.

Methods and systems are provided for dynamically adjusting broadcast beam patterns of a wavefront emitted by an antenna array based on the velocities of devices communicatively coupled to the base station associated with the antenna array. The broadcast beam patterns can be adjusted by modifying the broadcast mode or at least one phase, amplitude, or power of the at least one antenna associated with the base station. Adjusting the beam pattern, for example between multiple beams and a single unified beam, based on device types can improve the quality of service for the devices and reduce the processing burden of the base station.

Described embodiments provide devices and methods for directing portions of signals to reduce power consumption. A wearable device may comprise N antennas configured to wirelessly receive and/or transmit incoming and/or outgoing signals. The N antennas may be spatially disposed on the device to enable at least one of the N antennas to be clear from blockage by a body part of a user when the device is maintained or worn against the body part, wherein N is an integer value greater than or equal to 2. The wearable device may comprise N receive chains coupled to the N antennas via transmit-receive couplers, the N receive chains configured to process the incoming signals. The wearable device may comprise a transmit chain configured to generate the outgoing signals. The wearable device may comprise a RF controller circuitry configured to direct portions of the generated outgoing signals via the transmit-receive couplers to the N antennas.
