Abstract: A wireless device of the present disclosure may be able to reduce the time needed to determine a subarray and/or beamforming direction used for mmW communication. An apparatus may maintain first information associated with a correlation between each of a plurality of wireless device orientations and a plurality of nodes, at least one subarray, and a corresponding beamforming direction. The apparatus may communicate with a first node using a first beamforming direction selected from the first information. In certain aspects, the first beamforming direction may be correlated with a first orientation of a first subarray at the wireless device and the first node. The apparatus may perform a handoff procedure from the first node to a second node when a position of the first subarray changes from the first orientation to a second orientation.

Abstract: This disclosure generally relates to systems, devices, apparatuses, products, and methods for wireless communication. For example, a communication system may include a repeater having a first communication interface that receives a control message that indicates a measurement configuration for a second communication interface of the repeater that is different than the first communication interface. The repeater receives, via the second communication interface, a first signal at the repeater from a first device. The repeater also measures a power metric associated with the first signal based on the measurement configuration. In some implementations, a base station or another device (e.g., UE), may communicate with the repeater and take one or more actions based on the power metric measured by the repeater.

Abstract: Methods, systems, and devices for wireless communication are described. A wireless repeater beamforms a receive signal, at a first antenna array. The repeater retransmits, via a second antenna array, a beamformed signal. The repeater may adjust the receive and/or transmit beam in order to avoid signal interference caused by the retransmission. The repeater may monitor an output of a power amplifier (PA) in a signal processing chain and adjust a gain to a PA driver to the PA and/or a gain to one or more low noise amplifiers (LNAs) in the signal processing chain in order to improve or maintain transmission stability in the repeater.

Abstract: Methods, systems, and devices for wireless communications are described. A phase rotation adjustment may be applied in cases where a transmitted signal is heterodyned. For instance, a device (e.g., a base station, a user equipment (UE), a wireless repeater) may determine that a receiving device may receive a transmitted signal at a carrier frequency that is different from a carrier frequency used by a transmitting device (e.g., such as in the case of a wireless repeater relaying the signal from the transmitting device to the receiving device). A phase rotation adjustment may be applied by the device (e.g., the base station, UE, or wireless repeater) to account for the heterodyning. The phase rotation adjustment may be based on the carrier frequency used by the receiving device to receive the signal. In some cases, a receiving device may also apply the phase rotation adjustment following the demodulation of a received signal.
