Abstract: The described techniques relate to improved methods, systems, devices, and apparatuses that support modem control using millimeter wave (mmW) energy measurement. Generally, the described techniques provide for wireless device (e.g., wireless repeater) power savings in the absence of an attached (e.g., connected) user equipment (UE). For example, a wireless repeater may perform relay operations (e.g., amplification and forwarding operations) for communications between a base station and a UE in some channel (e.g., in a mmW channel). The wireless repeater may use energy measurements in the channel (e.g., analog mmW measurements) to control or configure a digital interface for monitoring out of band control information (e.g., in a sub-6 gigahertz (GHz) channel). For example, a wireless repeater may use energy measurements of signals transmitted by devices in a mmW band to configure (e.g., turn on) a digital interface of another modem to monitor for control information in a sub-6 GHz band.

Abstract: Methods, systems, and devices for wireless communications are described in which RF-domain wireless routers may repeat, extend, or redirect beamformed wireless signals received from one or more transmitters to one or more receivers. The router may receive transmissions at a mmW frequency using a first array of antenna elements, and provide the transmissions to a beamforming network, such as a Butler matrix, that outputs one or more a signals to a switching network. The switching network may perform switching to provide the one or more signals to desired inputs of an output beamforming network that outputs beamformed transmission beams via a second array of antenna elements.

Abstract: Certain aspects of the present disclosure provide systems and techniques for full-duplex communication. A first system is characterized by techniques for communicating in full-duplex utilizing the Butler matrix beamformer for generating a spatial beam to be used for both uplink and downlink signaling, wherein the signaling utilizes the same time and frequency resources. A second system is characterized by techniques for communicating in full-duplex utilizing the Butler matrix beamformer to generate two spatial beams, one to be used for downlink and one to be used for uplink signaling, wherein the signaling utilizes the same time and frequency resources. Accordingly, the systems and techniques described herein are directed to low complexity, multi-user full-duplex communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a repeater may transmit, via a first interface, information associated with a capability of the repeater to provide a wideband signal on a second interface. The repeater may receive via the first interface, a configuration for transmitting the wideband signal on the second interface, and may transmit the wideband signal on the second interface based at least in part on the configuration. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. A resource type associated with a transmission to be relayed by a wireless repeater may further be associated with a corresponding likelihood for subsequent forwarding activity (e.g., a corresponding likelihood a base station may send subsequent control information for configuring the wireless repeater to forward additional communications subsequent to the relayed transmission). Therefore, based on a resource type associated with a transmission configured by a wireless repeater configuration from a base station, a wireless repeater may efficiently configure a control interface, and control channel monitoring, subsequent to configured relay operations.

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.
