Abstract: Aspects of the present disclosure provide techniques for reducing channel state information (CSI) feedback overhead sent from one or more user equipments (UEs) to a network entity, such as a base station (BS) or gNodeB (gNB), while ensuring correct mapping of the CSI feedback at the network entity. In some cases, the overhead reduction may be achieved by converting the CSI feedback to size-reduced and further quantized representative coefficients (e.g., for multiple UEs). The quantized coefficients allow the network entity to recover the CSI feedback by de-quantizing and correctly mapping the quantized coefficients to recover the CSI feedback.

Abstract: Certain aspects of the present disclosure provide techniques that may be executed by a new radio (NR) gNB for sending signaling to a user equipment (UE), which may indicate information that may enable the UE to measure synchronization signal blocks (SSBs) that each have an associated range and an associated direction, for performing an initial access procedure.

Abstract: Aspects of the present disclosure provide techniques for physical uplink shared channel transmissions sent using multiple frequency domain resource allocations (FDRAs). According to certain aspects, a user equipment (UE) determines at least a first part frequency domain resource allocation (FDRA) and a second part FDRA, transmits a first part of a physical uplink shared channel (PUSCH) on the first part FDRA with a first precoder, and transmits a second part of the PUSCH on the second part FDRA with a second precoder.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate multiple channel state information (CSI) reports that are linked together for coherent joint transmission (CJT) with multiple transmit receive points (TRPs). The UE may transmit the multiple CSI reports that are linked. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a sounding reference signal (SRS) in multiple slots. A network entity may determine precoding weights in three domains based on the SRS and output reference signals that are precoded based on the precoding weights. The network entity may output control signaling that indicates reference signal resource grouping information that the UE is to use for channel estimations. The reference signal resource grouping information may specify whether the ports in one group are precoded with identical or different spatial, frequency, and time domain weights. A UE may receive the precoded reference signals and the grouping information and report estimated channel metrics and an indication of selected ports per group to the network entity. The network entity may determine precoding in three domains for subsequent downlink communications.

Abstract: A method of wireless communication by a base station includes receiving a channel state information (CSI) payload at a neural network CSI decoder. The method also includes decoding the CSI payload to generate a quantity (N) of precoding vectors for N transmission layers. The method further includes orthogonalizing the N precoding vectors to generate N orthogonal precoding vectors. The method still further includes transmitting, to a user equipment (UE), downlink data that is precoded in accordance with the N orthogonal precoding vectors.

Abstract: Certain aspects of the present disclosure provide techniques for reporting channel state information (CSI). According to certain aspects, a method for wireless communications by a user equipment (UE) generally includes generating channel state information (CSI) comprising a (at least one) fractional rank indication (RI) value for a set of candidate ranks, a first indication of a first layer or first singular vector, and a second indication of a second layer or second singular vector and transmitting the CSI to a network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first indication that the UE is within a distance threshold (e.g., in the near field) of multiple-in multiple-out (MIMO) communications from the base station. The UE may communicate with the base station via signaling including a second indication of antenna panel information of at least one of the UE or the base station, the communication based on the UE being within the distance threshold. The UE may receive, from the base station, a first beamformed signal on one or more first beams within the distance threshold, and the CE may receive, from the base station, one or more second beamformed signals on a second beam within the distance threshold, the second beam based on a channel response matrix that is estimated from the second indication and the first beamformed signal.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a base station may transmit, to a user equipment (UE), control signaling indicating a configuration for transmitting a reference signal for reconfigurable surface configuration. The base station may receive, via a reconfigurable surface, the reference signal based on transmitting the control signaling. For instance, the reconfigurable surface may reflect the reference signal to the base station using a first configuration of the reconfigurable surface. The base station may transmit, to a controller of the reconfigurable surface, a set of parameters for configuring the reconfigurable surface to a second configuration for communications between the base station and the UE based on receiving the reference signal via the reconfigurable surface.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device (e.g., a base station) may transmit, to a user equipment (UE), an indication of a field type of a field between the UE and the wireless device. The indication of the field type may include one or more bits indicating the field type, a measure indicating a likelihood that the field type includes a first field type as compared to a second field type, an indication that the first type is the same as a second field type configured at the UE, or any combination thereof. The UE may select between a first set of beam weight vectors and a second set of beam weight vectors based on the field type. The UE may communicate, with the base station, a reference signal using a beam generated using a first beam weight vector from the selected set.
