Antenna array reconfiguration at both ends of a millimeter wave link
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.
