Abstract: Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a user equipment and/or base station) may operate in a first mode in a wireless network over a radio frequency spectrum band. The wireless device may receive a signal indicating that a value of the radio frequency spectrum band has satisfied a threshold value. The wireless device may switch, based at least in part on the signal indicating that the value has satisfied the threshold value, from the first mode to a second mode for wireless communications in the wireless network, wherein a first length of a first synchronization signal block associated with the first mode is shorter than a second length of a second synchronization signal block associated with the second mode.

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.

Abstract: The base station that is configured to transmit in a beamformed manner may set different transmission rates for different directions of the beams. During an initial access stage, the base station may determine how densely user equipments are located in various regions surrounding the base station, and may assign more beams for transmission of an initial access signal in an area with more UEs. The apparatus may be a base station. The base station divides a region surrounding the base station into a plurality of sub-regions, where one region of the plurality of sub-regions covers a greater area than at least one other region of the plurality of sub-regions. The base station assigns each beam of a plurality of beams of the base station to a respective sub-region of the plurality of sub-regions. The base station transmits at least one initial access signal in each direction of the plurality of beams using a respective beam of the plurality of beams, each direction of the plurality of beams corresponding to a respective sub-region of the plurality of sub-regions.

Abstract: Certain aspects of the present disclosure provide techniques for user equipment (UE) positioning using one or more intelligent reflecting surfaces (IRSs). A method that may be performed by a UE includes for each IRS of the one or more IRSs: identifying a first IRS reflection center, measuring a first impulse response from the IRS to obtain a first measured impulse response representation, determining a first impulse response for a first ray reflected from the first IRS reflection center of the IRS, estimating a first position of the UE based on, at least, the first IRS reflection centers for each of the one or more IRSs and the first impulse responses for each of the one or more IRSs, and estimating a second position of the UE in an iterative manner until one or more conditions are satisfied.

Abstract: Methods and systems for operating a base station to reduce beam squinting include determining a lower bound on the number of directional beams used by the base station for millimeter wave wideband communications (e.g., based on operating conditions of the base station or wireless devices within the coverage area of the base station) and transmitting synchronization signal block (SSB) messages in an SSB Burst Set consistent with the determined lower bound on the number of directional beams used by the base station for millimeter wave wideband communications.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may receive, via a first interface of a repeater, information associated with a second interface of the repeater. The base station may determine a configuration for the second interface of the repeater based at least in part on the information associated with the second interface, and may communicate the configuration for the second interface of the repeater via the first interface. In some aspects, a repeater may transmit, to a base station via a first interface, information associated with a second interface of the repeater. The repeater may receive, via the first interface, a configuration for the second interface, and may configure the second interface based at least in part on the configuration. Numerous other aspects are provided.

Abstract: A node including an RU and a control entity is disclosed. The node may receive, from a base station at a control entity of the node, an indication of at least one obstruction for communication via at least one reflective surface. The indication may indicate to the control entity to utilize an RU of the node and the at least one reflective surface for communication. The node may configure, upon receiving the indication of the at least one obstruction, the RU and the at least one reflective surface for communication with the base station. The node may forward communication received from, or forward communication to, the base station via the RU and the at least one reflective surface based on the at least one obstruction for communication.

Abstract: Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

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.
