Abstract: Methods, systems, and devices for wireless communications are described. A base station may indicate to a UE a first set of uplink power control parameters associated with half-duplex communications and a second set of uplink power control parameters associated with full-duplex communications. Alternatively, the base station may indicate the first set of uplink power control parameters and a set of power offsets associated with full-duplex communications. The base station may indicate a first set of resources associated with the first set of uplink power control parameters and a second set of resources associated with the second set of uplink power control parameters or the set of power offsets. In response, the UE may transmit one or more uplink messages over one or more resources of the second set of resources in accordance with the second set of uplink power control parameters or the set of power offsets.

Abstract: Methods, systems, and devices for wireless communications are described. A controller of a reconfigurable intelligent surface (RIS) may transmit a capability message indicating a capability of one or more configurable elements of the RIS to direct incoming signals in one or more directions for one or more frequency bands. For example, the configurable elements may have an ability to act as transparent to the signal, to direct the signal in an interference safe direction or frequency, and/or to diffuse the signal across multiple directions or frequencies. The controller of the RIS may control the one or more configurable elements in accordance with the capability message and an activity status of the RIS to direct a signal to at least one direction. In some cases, a network entity may transmit an indication of the at least one direction to the RIS controller.

Abstract: A UE may train a NN, based on a blockage of a beam transmission, to indicate one or more beam weights in association with the blockage of the beam transmission. The UE may store, in an ML database, information indicative of at least one of the trained NN or the one or more beam weights indicated via the trained NN, such that the UE may communicate, to an ML server, the information via the trained NN. The ML server may train the NN, based on a TL/FL procedure for the one or more beam weights associated with the at least one blockage, to indicate one or more TL/FL beam weights in association with the at least one blockage, and communicate, to at least one UE, information indicative of at least one of the trained NN or the one or more TL/FL beam weights indicated via the trained NN.

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, an indication of a range of frequencies outside an operational bandwidth of the UE based at least in part on the range of frequencies being compatible with one or more sets of analog beamforming beam weights associated with the operational bandwidth. The UE may communicate, with the base station, based at least in part on transmitting the indication of the range of frequencies outside of the operational bandwidth of the UE. Numerous other aspects are provided.

Abstract: This disclosure provides systems, methods, and devices for wireless communication that support local light biasing for silicon photomultiplier (SiPM)-based photodetectors used in optical wireless communication (OWC). In a first aspect, a photodetector may include a silicon photomultipier (SiPM) having an input sensor configured to detect a light signal and an output interface configured to produce an output signal proportional to an intensity of the light signal detected at the input sensor, and a controllable light source positioned to emit a biasing light signal within a field of view of the input sensor, wherein the controllable light source is configured to emit the biasing light signal within a sensitivity range of the SiPM. When such photodetector is implemented in an OWC receiver, an analysis of the output signal allows the OWC receiver to adjust the biasing light at the controllable light source. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine its position by receiving locations from one or more other UEs capable of network-based positioning. For example, a second UE may determine its location using network-based positioning and may transmit its location information to the first UE. The first UE may determine its location based on the received location information (e.g., by calculating a weighted average of different locations, by setting its location to be the same as the received location). In some cases, the first UE may receive location information from other UEs during or after a discovery process with other UEs. In some other cases, the first UE may receive messages (e.g., periodic safety messages) from the other UEs, and the messages may each include location information of the respective other UEs.

Abstract: Method and apparatus for null-forming at bidirectional smart repeaters. The apparatus transmits, to a repeater, a repeater configuration. The repeater configuration configures the repeater to beam shape at least one beam of the repeater to suppress at least one side lobe of the at least one beam. The apparatus communicates with the repeater based on the repeater configuration. The apparatus receives, from the repeater, information related to an existing codebook of the repeater and associated beam forming capabilities of the repeater. The apparatus receives, from the repeater, information related to a null-forming codebook configured at the repeater.

Abstract: Aspects relate to random access procedures. A base station may transmit a random access response message to a user equipment (UE) on a downlink control channel at a first monitoring occasion and transmit at least one repetition of the random access message at at least one offset from the first monitoring occasion. The base station may also transmit an indication of the offset(s) to the UE. Upon receiving the indication of the offset(s), the UE may monitor for the random access response message on the downlink control channel at the first monitoring occasion and at the monitoring occasion(s) for the repetition(s). A UE may identify a first radio network temporary identifier (RNTI) used to affect a physical downlink control channel (PDCCH) sent within a random access response (RAR) window and determine based on the first RNTI that the PDCCH is one of a plurality of PDCCH repetitions.
