A wireless communication device can include modem circuitry to connect the UE to a repeater over a side-link connection. The device can also include processing circuitry to control a repeater beamforming process to select a beam angle from the repeater to a base station and initiate a communication procedure using the selected beam angle. Other methods, systems and apparatuses are described.

Remote beam steering for a millimeter wave repeater

A wireless communication device can include a communication control interface. Beamforming circuitry coupled to the communication control interface receives, over the communication control interface, an index value into a coarse codebook and an offset vector. The index value indicates a value within the coarse codebook, and the offset vector indicates an offset value for a desired beam relative to the index value. The beamforming circuitry determines a new beam direction based on the index value and the offset vector using one of interpolation and extrapolation.

Codebook extrapolation

A wireless communication device can include an oscillator circuit. The oscillator circuit can include an oscillator and measurement circuitry coupled to the oscillator. The measurement circuitry can receive an output signal of the oscillator and measure oscillator error by comparing the output signal of the oscillator to a nominal frequency for an amount of time. The oscillator circuit can further include adjustment circuitry to adjust an oscillator frequency of the oscillator based on the measured oscillator error.

Opportunistic calibration of a clock

In a communication device and corresponding methods, a hierarchical, reduced power, beam search process includes a hierarchical activation of the radio frequency frontend (RFFE), transceiver, and baseband integrated circuit (BBIC) for a beam searching operations. For example, a first signal metric measurements can be performed to determine signal information. An operating mode can be determined based on the signal information. In a first operating mode, one or more second signal metric measurements can be performed for a subset of beamforming configurations of the wireless communication device to determine beamforming information. In a second operating mode, one or more third signal metric measurements can be performed on the beamforming configurations to determine the beamforming information.

Communication scanning method and system

Embodiments of an apparatus of a user equipment (UE) configured for operation in a fifth-generation system (5GS) are described herein. The UE comprises first and second array antennas for transmission of mmWave signals including a sounding-reference signal (SRS). In response to decoding radio-resource configuration (RRC) signalling that indicates antenna switching for SRS, the UE initiates a countdown timer and transitions the second array antenna from a low-power state to an active state. If a downlink control information (DCI) indicating SRS antenna switching is not received while the countdown timer is active, the UE generates a command to transition the second array antenna to a low-power state upon expiration of the countdown timer.
