Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a configuration that may identify a set of time and frequency resources for transmission of sounding reference signals, the set of time and frequency resources including a plurality of subsets of time and frequency resources. Each subset of time and frequency resources of the plurality of subsets of time and frequency resources may be associated with a corresponding value of a plurality of values of a partial frequency parameter. The UE may receive control signaling indicating a value of the partial frequency parameter of the plurality of values. The UE may transmit a sounding reference signal on a subset of time and frequency resources of the plurality of subsets of time and frequency resources that corresponds to the value of the partial frequency parameter indicated by the received control signaling.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station via a reconfigurable surface, a set of reference signals reflected by the reconfigurable surface using a set of precoder configurations. In some aspects, the set of reference signals are transmitted within a set of reference signal occasions of a sweep procedure associated with configuring the reconfigurable surface with different precoder configurations of the set of precoder configurations for reflecting signals. The UE may additionally transmit, to the base station via the reconfigurable surface, a feedback message including an indication of at least one precoder configuration of the set of precoder configurations based on receiving the set of reference signals. The UE may then receive, from the base station via the reconfigurable surface, a downlink transmission based on transmitting the feedback message.

Abstract: Aspects of the present disclosure relate to techniques, methods, devices, systems, and non-transitory computer readable medium for generating codebooks for reconfigurable intelligent surfaces (RIS) s. For example, a RIS controller generates a codebook for a RIS by computing weights using a discrete Fourier transform (DFT) function or a fractional Fourier transform (FrFT) function, based on reference signals (RSs) transmitted by a transmitter. The weights correspond to the RIS elements or a subset of the RIS elements. In some aspects, the computation of the weights may include oversampling factors that allow for a higher resolution of the weights and improved search for an optimal precoding setting. Different sets of weights may be used for different incoming beams. The RIS controller may be trained with a pair of transmitter and a receiver to identify/generate the codebook for an optimized set of weights under specific situations.

Abstract: Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may transmit a trigger message to a second UE, where the trigger message triggers a channel state information (CSI) report that includes a first CSI reporting mode of a set of CSI reporting modes and a reporting quantity for the first CSI reporting mode. For a first reporting quantity, the first UE may trigger the second UE to transmit a CSI reference signal (RS), and the first UE may then receive the CSI-RS to determine CSI based on the CSI-RS. Additionally or alternatively, for other reporting quantities, the first UE may transmit the CSI-RS to the second UE, and the second UE may transmit channel state feedback to the first UE based on measuring CSI for the received CSI-RS, where the first UE determines the CSI based on the channel state feedback.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station and via a reconfigurable intelligent surface (RIS), a synchronization signal block (SSB) corresponding to a first SSB type configured for RIS-assisted procedures. The UE may select a random access channel (RACH) occasion including multiple physical random access channel (PRACH) transmission slots based at least in part on receiving the SSB corresponding to the first SSB type. The UE may transmit, to the base station, a PRACH communication in the multiple PRACH transmission slots of the RACH occasion. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE) generally including receiving, from a network entity, signaling scheduling a number of Physical Downlink Shared Channel (PDSCH) repetitions for the UE, successfully decoding one of the PDSCH repetitions that was transmitted before a remaining one or more of the PDSCH repetitions, and transmitting early acknowledgment feedback to a network entity indicating the successful decoding, wherein the early acknowledgment feedback is transmitted before transmission of at least one of the remaining PDSCH repetitions.

Abstract: Techniques are discussed herein identify transmission strategies and to communicate those identified transmission strategies in a transparent communication environment. In some examples, a user equipment (UE) may identify a new transmission strategy for a downlink channel different from a current transmission strategy for the down link channel. The UE may transmit a channel state information (CSI) message that includes an indication of the new transmission strategy identified by the UE. In some examples, a base station may identify the new transmission strategy for the downlink channel. The base station may transmit a codebook subset restriction (CSR) indicator that includes an indication of the new transmission strategy identified by the base station. In some examples, the UE may modify its feedback strategy based on the new transmission strategy.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques provide for a base station using antenna groups configured at a user equipment (UE) for CSI reporting. The base station may transmit an indication of the antenna group that the UE is to use for measuring and reporting CSI. Based on the received indication, the UE may measure a reference signal transmitted by the base station and received at the UE using one or more antennas of the antenna group in accordance with the indication. The UE may transmit, to the base station, a CSI report that is based on the measuring of the reference signal using the one or more antennas of the antenna group.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify multiple resource element (RE) segments associated with a scheduled communication that includes a source bit sequence, each RE segment including one or more REs in one or more scheduled physical resource blocks associated with the scheduled communication. The UE may communicate with a device based at least in part on respective energies on the one or more REs included in the multiple RE segments associated with the scheduled communication. For example, communicating with the device may include transmitting or detecting a sub-sequence associated with an RE segment using a neural network that modulates the sub-sequence associated with the RE segment to the one or more REs in the RE segment. Numerous other aspects are provided.
