Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a reflecting device may generate a multi-peak reflection beam that spatially multiplexes a first reflected signal of a first signal and a second reflected signal of a second signal. The reflecting device may receive the first signal and the second signal. The reflecting device may reflect the first signal and the second signal to output a spatially multiplexed reflected signal using the multi-peak reflection beam. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques may enable transmitting and receiving devices to increase an effective aperture size of transmitting and receiving antenna arrays, which may increase an achievable rank of spatially multiplexed communications. For example, one or both of the transmitting device and the receiving device may use a reflective component to reflect signals transmitted between the devices, which may allow for larger effective aperture sizes without increasing a physical distance between antenna elements. In some examples, the reflective component may be a static concave mirror associated with a predetermined weight vector and focal point. In some examples, the concave mirror may be a reflective intelligent surface (RIS) of reflective elements with reflective properties which may be dynamically adjusted to various weight vectors. An orientation of the RIS may be adjusted to steer a beam in various directions in space.

Abstract: Methods, systems, and devices for wireless communication are described. In some systems, a first device may include a first circular antenna array including a first quantity of antenna subarrays. A second device may include a second circular antenna array including a second quantity of antenna arrays. Each antenna subarray may include one or more antenna elements. The first device may transmit one or more reference signals to the second device. The second device may transmit a feedback message to the first device based on the reference signals. The feedback message may include an indication of sets of beamforming weights or information for determining the sets of beamforming weights based on the second quantity of antenna subarrays being different than the first quantity of antenna subarrays. The first device may transmit one or more signals concurrently to the second device based on the sets of beamforming weights.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless devices that relay directional wireless signals). For example, aspects of the present disclosure may help enable repeaters to provide greater assistance in an access procedure, for example, by generating and sending SSBs without (or with limited) gNB involvement and monitoring for RACH-related transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless repeater may communicate with multiple base stations, and the wireless repeater may identify a first base station as a primary base station. The wireless repeater may monitor for and receive control information from the primary base station, where the control information may include control information from a second base station and used by the wireless repeater to communicate with one or more UEs connected to the second base station. The primary base station may receive an indication of the control information from the second base station via a backhaul link. In other examples, the wireless repeater may monitor for control information from the two or more base stations based on a control signaling pattern. For example, the wireless repeater may be configured with periodic time intervals for monitoring for control signaling from respective base stations.

Abstract: Aspects of the disclosure relate to beam configuration for RF repeaters. An RF repeater is configured to measure received power of one or more signals in the repeater for each of a plurality of beam directions. Further, the repeater determines a beam forming configuration for a fronthaul link between the repeater and at least one base station based on the measured received power of each of plurality of beam directions. The repeater may also be configured to determine beam configurations for access links between the repeater and user equipment.

Abstract: This disclosure provides systems, methods and apparatuses for efficient signaling of feedback regarding communications of a relaying operation. In some aspects, a relay node may defer feedback regarding reception of a first communication until relaying feedback regarding the payload of the first communication, thereby reducing overhead and signaling burden. In some aspects, a relay node may skip the transmission of feedback regarding the first communication altogether, either on the assumption that the link between the relay node and the first wireless node is reliable, or on the basis of the first wireless node being able to infer the reception of the first communication based on subsequent communications. In some aspects, a relay node may be enabled to skip forwarding of feedback from a second wireless node, such that the first wireless node can infer that the payload was received if no negative feedback associated with the payload is received.

Abstract: Aspects of the disclosure relate to a repeater in a wireless communication system. The repeater is configured to detect synchronization signals broadcast by one or more cells in the communication system, and then process at least one portion of the detected synchronization signals in the repeater. From the detected synchronization signals, the repeater determines at least one of a cell selection and a beam forming configuration for at least a fronthaul link between the repeater and a base station in the communication system based on the processing of the at least one portion of the detected synchronization signals. This allows the repeater to gain information for beam forming without the need for digital processing and to establish a control link with the base station or cell.
