Abstract: A method, apparatus, and system for barring at least one UE from communicating with one or more RISs is disclosed. A base station may determine to bar at least one UE from communicating with one or more RISs of a plurality of RISs. The base station may transmit, to the at least one UE, a barring indication for the one or more RISs. The barring indication may identify the one or more RISs with which the at least one UE is barred from communicating. The UE may determine to refrain from communicating with the one or more RISs based on the barring indication. The UE may communicate with the base station based on the determination to refrain from communicating with the one or more RISs.

Abstract: Methods, systems, and devices for wireless communications are described. In a wireless communications system, a user equipment (UE) may receive an indication of a configuration (e.g., via control signaling) of a set of reconfigurable intelligent surfaces (RISs). The UE may select a primary RIS for bidirectional wireless communication (e.g., uplink and downlink) and one or more secondary RISs for unidirectional wireless communication (e.g., uplink or downlink) based on the configuration. The UE may use the one or more secondary RISs to enable higher throughput and extended coverage in the wireless communication system. The UE may communicate with the base station using the primary RIS, or the secondary RIS, or both.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive at least one first synchronization signal within a first set of synchronization signals associated with a first network node. The UE may further receive at least one second synchronization signal within at least one second set of synchronization signals associated with at least one second network node. The at least one second set of synchronization signals is multiplexed with the first set of synchronization signals. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first device (e.g., a base station) may transmit reference signals to a second device (e.g., a user equipment (UE)) via transmitter antenna circles. The second device may receive and measure the reference signals via corresponding receiver antenna circles. Both the transmitter antenna circles and the in receiver antenna circles may include a center antenna circle and one or more peripheral antenna circles. The second device may transmit channel gain measurements to the first device based on measuring the reference signals. The first device may determine orbital angular momentum (OAM) modes, a power loading scheme, or both for the transmitter antenna circles based on the channel gain measurements. The first device may transmit OAM transmissions to the second device based on the determined OAM modes, the power loading scheme, or both. The OAM transmissions may have different OAM states, polarizations, or both.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a configuration for use by the UE to select one or more of a plurality of resource sets for a bandwidth part (BWP) for the UE, where each of the resource sets comprise reference signal resources that correspond to one or more antenna ports of the UE. The UE may receive, from the base station, an activation message instructing the UE to activate at least one resource set of the plurality of resource sets for reference signal transmission using the BWP. The UE may transmit a reference signal over the activated resource set using the BWP and at least one antenna port of the one or more antenna ports based at least in part on the activation message, the antenna port corresponding to the activated resource set.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes transmitting, to a base station, a capability parameter indicating one or more predictive retransmission feedback capabilities of the UE, receiving, from the base station, an activation indicator that indicates a predictive retransmission feedback procedure is enabled, receiving data from the base station, and transmitting a predictive retransmission feedback associated with the data to the base station, the predictive retransmission feedback being computed, in accordance with the activation indicator, prior to completing a decoding of the data.

Abstract: Methods, systems, and devices for wireless communications are described that support signaling of compressed gradient vectors in a machine learning system that utilizes federated learning. The compressed gradient vectors may be used to report stochastic gradients from multiple edge devices (e.g., multiple user equipment (UE) devices) that are combined into a global model at an edge server (e.g., a base station). A base station may configure a UE with one or more parameters for quantizing a local stochastic gradient, and for reporting the quantized local stochastic gradient in a set of compressed gradient vectors. Each vector of the compressed gradient vectors may be associated with a different stage of a multi-stage compression procedure for reporting the local stochastic gradient, and multiple reports from multiple UEs may be aggregated in a federated learning procedure associated with a machine learning algorithm.

Abstract: A network entity can provide a plurality of downlink (DL) transmissions using a plurality of distributed transmission and reception points (TRPs) in a multiple-in-multiple-out (MIMO) system. The network entity can obtain delay metrics of the DL transmissions from the UE. The UE can generate the delay metrics based on measurements of DL reference signals from the distributed TRPs. The network entity can pre-compensate the DL transmissions based on the delay metrics.
