Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted by a base station. The UE may receive system information that includes reconfigurable intelligent surface (RIS) or repeater assisted initial access information that identifies a set of SSBs that are associated with an RIS or a repeater and a modulation signature associated with the RIS or the repeater. The UE may selectively perform initial access using the SSB or search for another SSB based at least in part on the RIS or repeater assisted initial access information. Numerous other aspects are described.

Abstract: A method of wireless communication at a first network node is disclosed herein. The method includes performing beam training with a RIS-MT array, wherein the RIS-MT array is associated with a RIS array. The method includes identifying, based on the beam training, a first beam for communication with the RIS-MT array. The method includes transmitting communication to the RIS array for reflection or refraction to a wireless device using a second beam based, at least in part, on the first beam identified for the RIS-MT array.

Abstract: Methods, systems, and devices for wireless communication are described. A receiver may orient its antenna arrays based on signaling from a transmitter and a distance between the receiver and the transmitter. The transmitter may transmit an indication of an orientation of its antenna array. The receiver may receive the indication and may determine the distance between the receiver and the transmitter. Based on whether the distance between the receiver and the transmitter satisfies a threshold distance from the transmitter, the receiver may select an orientation for its antenna array. The receiver may select a first antenna orientation based on the distance failing to satisfy the threshold distance and may select a second orientation based on the distance satisfying the threshold distance

Abstract: Certain aspects of the present disclosure provide techniques that may allow a base station and user equipment (UE) to use uplink transmission configuration indication (TCI) states. An example method generally includes providing, to a network entity, signaling indicating the UE supports uplink Transmission Configuration Indicator (TCI) states indicating one or more quasi co-location (QCL) types for one or more reference signals (RS) to be applied to an uplink transmission, receiving UL TCI after sending the indication, and sending the uplink transmission in accordance with the uplink TCI.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment may perform retroreflection on a waveform received from a wireless device (e.g., such as a network entity or a second UE) to assist or perform various operations, such as identifying positioning information of the UE, broadcast signaling, or sidelink relay discovery. For example, the UE may receive control signaling indicating a set of resources during which the UE activates retroreflection communications between the UE and the second wireless device. The UE may monitor the set of resources for a waveform from the second wireless device and transmit a retroreflected signal to the second wireless device based on the received waveform. In this way, the second wireless device may identify a position of the UE based on the retroreflected signal, discover the presence of the UE for broadcast or sidelink relay discovery based on the retroreflected signal, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a network entity via an optical wireless communication link, a first optical wireless signal using photodetectors positioned on a photodetector panel of the UE. The photodetector panel may include a hole around which the photodetectors are positioned and may be located a first distance from a curved optical device of the UE via which the first optical wireless signal is received. The UE may transmit, to the network entity via the optical wireless communication link, a second optical wireless signal using a light source of the UE that is located a second distance from the curved optical device via which the second optical wireless signal is transmitted. The second optical wireless signal may pass through the hole in the photodetector panel based on the second distance being greater than the first distance.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may store a beamforming calibration configuration including one or more beamforming parameters. The UE may detect one or more trigger conditions. The UE may transmit a beamforming calibration update request as a result of detecting the one or more trigger conditions. The UE may receive one or more beamforming assistance signals in response to the beamforming calibration update request. The UE may update at least one of the one or more beamforming parameters in the beamforming calibration configuration based, at least in part, on the one or more beamforming assistance signals.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit, to a base station, a capability value set list identifying one or more capability sets. The UE may transmit, to the base station, a channel state information (CSI) report that includes a capability set identifier identifying a capability set of the one or more capability sets of the capability value set list. The UE may receive a feedback message indicating whether the base station successfully received the CSI report and whether to retransmit information identifying the capability set identifier. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity may utilize parameterized codebooks to support reconfigurable intelligent surface (RIS)-assisted communications. For example, a network entity may receive an indication of one or more codebooks associated with respective sets of parameters including one or more of a respective field of view (FOV) or a respective configuration switching latency, among other parameters. The network entity may select a codebook for RIS-assisted communications based on whether the codebook satisfies one or more thresholds. The network entity may indicate the codebook to a RIS controller and may communicate one or more messages with a user equipment (UE) using a RIS in accordance with the indicated codebook.
