Abstract: In one aspect, a method for wireless communication includes transmitting, by a wireless communication device, symbol configuration information for a particular transmission time interval (TTI). The symbol configuration information indicates one or more subsets of symbols of the particular TTI, and the wireless communication device is operating in a full duplex mode. The method for wireless communication further includes transmitting, by the wireless communication device, Quasi-Colocation (QCL) information for one or more subsets of the symbols, where the QCL information indicates multiple QCL per TTI. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A repeater may transmit a beacon signal that indicates a presence of the repeater, where the repeater is configured to repeat signals to one or more user equipments (UEs) within a wireless communications system. The repeater may receive a signal from at least one base station within a time-frequency resource that is shared by a plurality of neighboring base stations in response to transmitting the beacon signal. The repeater may transmit an amplified version of the received signal to the one or more UEs.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine, for full-duplex mode communication on a first link and a second link, a timing adjustment to at least one of a first timing or a second timing, wherein the timing adjustment is to cause a delay between clutter reflection from a first signal and an occurrence of a second signal to occur during a cyclic prefix of the second signal; cause the timing adjustment to be applied to the at least one of the first timing or the second timing; and communicate in the full-duplex mode with a first node and a second node in accordance with the timing adjustment, wherein communicating includes transmitting the first signal to the first node and receiving the second signal from the second node. Numerous other aspects are provided.

Abstract: A node may activate, in each iteration of a plurality of iterations, a respective segment of a plurality of segments of an IRS of the node. Each iteration of the plurality of iterations may correspond to one segment of the plurality of segments. The apparatus may receive, from the first wireless device, an indication of a second configuration for the node to generate one or more reflected beams toward the first wireless device or the second wireless device. The second configuration may be based on an interpolation process based on a plurality of phases or phase derivatives associated with the plurality of segments. The apparatus may forward, from the first wireless device to the second wireless device or from the second wireless device to the first wireless device, communications via the IRS based on the second configuration and the one or more reflected beams.

Abstract: Methods, systems, and devices for wireless communications are described that provide a repeater for beamforming a received signal at a millimeter wave (mmW) radio frequency via one or more scan angles or beamforming directions and then retransmitting and beamforming the signal at the mmW radio frequency. Repeaters may include analog and digital components for downconverting on the received signal to reduce a frequency of the signal from the mmW frequency to an intermediate frequency (IF) or baseband frequency, and then filtering the downconverted signal to reduce interference. The filtering may include digital filtering or a combination of analog and digital filtering, in which a set of filter coefficients for the digital filtering is selected based on beamforming parameters used to receive the signal, retransmit the signal, or both. The repeater may then upconvert the filtered signal back to the mmW frequency for the retransmission of the signal.

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 communications are described. A first wireless device may receive a measurement configuration, from a second wireless device, to support full-duplex operation using a shared resource. The first wireless device may transmit, via the shared resource, a first signal via a first transmission beam using a first antenna array of the first wireless device. The first wireless device may monitor, in accordance with the measurement configuration, the shared resource using a first receive beam via a second antenna array of the first wireless device. The first wireless device may then transmit a measurement report to a second wireless device based on the monitoring. The second wireless device may transmit, to the first wireless device, a duplexing configuration configuring the full-duplex operation of the first wireless device based on the measurement report.

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.
