    Abstract: Disclosed is a method for wireless communication for determining the position of a wireless node. The method comprises receiving a set of reference signals from a set of at least four positioning devices, wherein the positioning devices are not arranged in a single plane. A signal propagation delay of each one of the set of reference signals is determined and a position of each one of the set of positioning devices is obtained. A convex localization problem is solved for the wireless node based at least in part on the determined signal propagation delay of each one of the set of reference signals and the position of each one of the set of positioning devices. The position of the wireless node is determined based at least in part on solving of the convex localization problem.

    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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, from a repeater having a first interface and a second interface, information associated with one or more capabilities of the repeater, the second interface being different from the first interface. The base station may determine an operation mode for the repeater based at least in part on the information associated with the one or more capabilities of the repeater, and may communicate with the repeater via the first interface or the second interface. In some aspects, a repeater may transmit to a base station via a first interface, information associated with one or more capabilities of the repeater, and may communicate via the first interface or via a second interface in accordance with an indicated operation mode, the second interface being different from the first interface. Numerous other aspects are provided.

    Abstract: A node including a non-planar reflective surface is disclosed. The node may receive, from a base station, an indication of a surface configuration of at least one convex reflective surface of the node. The indication may indicate that the surface configuration corresponds to at least one of a broadcast configuration or a UE-specific configuration. The node may configure, upon receiving the indication of the surface configuration, the at least one convex reflective surface based on the surface configuration. The surface configuration may correspond to at least one of the broadcast configuration or the UE-specific configuration. The node may forward communication received from, or forward communication to, the base station based on the surface configuration of the at least one convex reflective surface.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive a random access channel (RACH) message. The base station may determine, based at least in part on the RACH message, whether the RACH message was transmitted directly to the base station by a user equipment (UE) or whether the RACH message was relayed from the UE to the base station via a millimeter wave repeater. The base station may perform a beam management procedure based at least in part on the determination. Numerous other aspects are provided.
