Abstract: Methods, systems, and devices for wireless communications are described that provide for channel state information (CSI) feedback for multiple discrete Fourier transform (DFT) beams on multiple transmission layers. A user equipment (UE) may report a total number of non-zero power DFT beams across all of the transmission layers. The UE may be configured with a total number of leading beams (Ktotal) across all of the transmission layers for which to provide high quantization feedback. When the total number of non-zero DFT beams across all the transmission layers exceeds the configured total number of leading beams across all the transmission layers, the UE may report high-resolution quantization feedback for Ktotal non-zero power precoding coefficients having the highest amplitude coefficients, and may report low-resolution quantization feedback for the remaining non-zero power precoding coefficients. A base station may receive the CSI feedback to determine a precoding matrix.

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 (BS), a first signaling communication that configures a plurality of transmit precoder matrix indicator (TPMI) and sounding reference signal (SRS) resource indicator (SRI) pairs. The plurality of TPMI and SRI pairs may be for transmitting respective physical uplink shared channel (PUSCH) communications to the BS. The UE may receive, from the BS, a second signaling communication that indicates an update to a TPMI and SRI pair of the plurality of TPMI and SRI pairs. The UE may transmit, to the BS, a PUSCH communication, of the respective PUSCH communications, based at least in part on the update to the TPMI and SRI pair. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for wireless communications are described. Techniques are described for a user equipment (UE) to trigger a sidelink channel state information (CSI) procedure without an associated data grant. In some cases, a CSI procedure may be triggered by sending a sequence on a specific resource. In some cases, a CSI procedure may be triggered by a sidelink control information (SCI) message which does not include a sidelink data grant. Techniques are described which avoid CSI reference signal (CSI-RS) resource collision. For example, CSI-RS resources may be selected based on channel sensing, UE identifiers, or a combination thereof. In some cases, UEs may be configured subsets of a CSI-RS resource pool for sending CSI-RS.

Abstract: Methods, systems, and devices for wireless communications at a are described. A first device (e.g., a transmitting device) may receive, from a second device (e.g., a receiving device), an indication of one or more parameters associated with communications between the second device and the first device. The first device may determine a transmitter circle of a set of transmitter circles for an orbital angular momentum (OAM) mode of a set of OAM modes for communications with the second device based on the one or more parameters. The first device may transmit a message to the second device using the transmitter circle according to the orbital angular momentum mode based the determining.

Abstract: Methods, systems, devices, and apparatuses for wireless communications that support transmission diversity enhancement for uplink control channel are described. Generally, the described techniques provide for enhanced performance of an uplink control channel such as a physical uplink control channel (PUCCH) through the use of transmission diversity. In some cases, multiple input multiple output (MIMO) techniques may be supported for transmission of an uplink control channel for a given format suitable for transmission diversity enhancement. A resource block (RB) used in an uplink control channel transmission may contain a number of resource elements (REs) across one or more resource blocks. According to some aspects, a transmit diversity scheme may be employed at the RE level through application of different spatial precoders for different groups of REs of a given RB.

Abstract: Aspects of the disclosure relate to the generation of channel state reports. A base station transmits a reference signal over a plurality of ports. A user equipment (UE) receives the reference signal and measure amplitudes of the reference signal over a plurality of ports. A first subgroup of the plurality of ports and a second subgroup of the plurality of ports are determined. In embodiments, the port groupings may be determined by the base station, which transmits an identification of the groupings to the user equipment. Alternatively, the UE may determine the port groupings. After determining the port groupings, the UE separately quantizes and normalizes the measured amplitude values in each port grouping. The UE may also separately quantize and normalize the phase measurements in each port groups. The UE generates a channel state report based on the normalized and quantized amplitude and phase values.

Abstract: A method includes receiving, by a user equipment (UE) device, a joint transmission of channel state information (CSI) reference signals (CSI-RS) from a first transmission and reception point (TRP) associated with a wireless network and at least a second TRP associated with the wireless network. The method further includes determining a joint rank parameter associated with the joint transmission and accessing, based on the joint rank parameter, a rank-to-port mapping codebook to determine a port index parameter. The method further includes, after determining the port index parameter, communicating, by the UE device, with one or more of the first TRP or the second TRP. Other aspects and features are also claimed and described.
