Abstract: Methods, systems, and devices for wireless communications are described. One method may inlcude a base station or other device estimating an intended coverage area of all possible communication devices that are to be serviced by the base station or other device. The base station or other device may dynamically optimize at least one transmission metric such as a codebook, in response to a change in the coverage area. Another method may include a base station estimating a dynamic coverage area of a set of all possible user equipments or devices to be serviced, and dynamically optimizing a codebook structure in response to a change in the coverage area. Another method may include the base station determining a use-case of the set of all possible user equipments to be serviced by the base station, and hard-coding a metric corresponding to the use case.

Abstract: Wireless communications systems and methods related to mitigation of calibration errors are provided. A base station (BS) transmits, via an antenna array including a plurality of antenna elements, a first communication signal using a first number of the plurality of antenna elements and a first transmission power level to a user equipment (UE). The BS receives from at least one UE, a measurement report based on the first communication signal. The BS transmitting a second communication signal using a second number of the plurality of antenna elements and a second transmission power level based on the one or more measurement reports. At least one of the first number of the plurality of antenna elements is different from the second number of the plurality of antenna elements, or the first transmission power level is different from the second transmission power level. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a first radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the transmitted signal at the first radio frequency via one or more scan angles or beamforming directions. Repeaters may perform heterodyning or downconverting on the received signal to reduce a frequency of the signal from the first frequency to an intermediate frequency (IF), and then band-pass filter the IF signal around a desired center frequency. The repeater may then heterodyne or upconvert the filtered IF signal back to the first frequency for the retransmission of the signal.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a repeater may receive a first signal from a transmitting device and determine an amplified version of the signal may not be successfully received by a receiving device. The repeater may transmit a mode switch message to the transmitting device to indicate a request for the transmitting device to switch to a transmission mode associated with one or more different transmission parameters based on detecting that the amplified version of the signal may not be received by the receiving device. The transmitting device may adjust one or more transmission parameters according to the mode switch message and may transmit a second signal to the repeater based on the adjusted transmission parameters. The repeater, operating according to the mode switch message, may receive the second signal and transmit an amplified version of the second signal to the receiving device.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a first device and a second device may communicate over a communication link using a set of antenna elements. The first device may identify one or more antenna array reconfiguration trigger conditions and may correspondingly select a first subset of antenna elements for operation. The first device may transmit a message to the second device including an indication of the antenna array reconfiguration at the first device, a request for the second device to modify the second device's antenna array configuration, or both. The second device may receive the message and, based on the indication or the request, may modify its antenna array configuration. For example, the second device may select a second subset of antenna elements based on the selected first subset of antenna elements. The devices may communicate using their modified antenna array configurations.

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 bidirectional wireless repeater may receive a first waveform during a first time domain duplexing period via a first antenna array and may transmit the first waveform at a second antenna array during the first time domain duplexing period. A di-pole di-throw (DPDT) switch may be coupled to the first and second antenna arrays and may switch the arrays during a guard period between the first time domain duplexing period and a second time domain duplexing period. The DPDT switch may toggle the first and second antenna arrays between transmit and receive modes.

Abstract: Wireless communications systems and methods related to providing user interfaces to inform a user of an antenna signal blockage at a wireless communication device are provided. A wireless communication device receives information associated with at least one antenna of the wireless communication device indicating that a signal path of the at least one antenna is at least partially blocked by an object. The wireless communication device outputs, via a user interface of the wireless communication device, an indication that the signal path of the at least one antenna is at least partially blocked.
