    Abstract: Methods, systems, and devices for fast beam selection via user equipment (UE) receive (Rx) beam selection reporting are described. A UE may transmit a beam selection report conveying a selected Rx beam, position, and orientation to a network entity. The network entity may build a database with the conveyed information. The network entity may “tag” each position for which a UE has transmitted a beam selection report and, if another UE gets close to a “tagged” position, the network entity may indicate the associated position, orientation, selected Rx beam, and a corresponding transmit (Tx) beam to that UE. The UE may use the information to select Tx and Rx beam search windows and window centers. Compared to other methods, the process described herein may result in a smaller search window, decreased complexity of the beam selection process, decreased power consumption, decreased latency, and more accurate tracking of UE dynamics.

    Abstract: Aspects are provided which allow for a base station to transmit code blocks according to a frequency first per layer (FFPL) mapping, and for a UE to decode received code blocks according to the FFPL mapping. The base station maps a plurality of code blocks to multiple layers, where each of the code blocks is mapped to a plurality of resource elements initially by frequency and subsequently by time on only a single layer of the multiple layers. The base station then transmits data including the code blocks to a UE. Afterwards, the UE receives the data including the mapped code blocks in multiple layers from the base station, and the UE decodes the code blocks based on the mapping. Thus, improvements in link efficiency, reliability, and reduced power consumption compared to frequency first (FF) mapping approaches may be achieved.

    Abstract: Apparatus, methods, and computer program products for improving precoding downlink signaling are provided. An example method may include determining one or more noise covariance parameters for a noise covariance report, the noise covariance parameters being associated with a noise covariance matrix for whitening. The example method further may include transmitting, to a base station, the noise covariance report including the one or more noise covariance parameters or a noise whitening matrix for the whitening, the noise covariance report being transmitted based on a transmission periodicity of one or more slots.

    Abstract: Methods, systems, and devices for wireless communication are described. A first user equipment may receive, from a network entity, information indicating a resource allocation associated with a physical downlink shared channel (PDSCH) for a second user equipment and an indication to measure a demodulation reference signal (DMRS) associated with the PDSCH for the second user equipment. The second user equipment may be in spatial angular proximity to the first user equipment. The first user equipment may measure the DMRS associated with the second user equipment, and may transmit, to the network entity, a beam management report including measurements associated with the DMRS for the second user equipment. Based on the measurements associated with the DMRS for the second user equipment, the network entity may adjust a directional beam associated with the first user equipment.

    Abstract: Certain aspects of the present disclosure provide techniques for channel aware demodulation reference signals (DMRS). An example method, performed at a user equipment (UE), generally includes receiving a message indicating one or more parameters for dynamic DMRS resource allocation, and communicating during one or more periods using DMRS resources dynamically allocated for the one or more periods based on the one or more parameters.

    Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may transmit a first report indicating a capability to support per codeword demodulation for a set of codewords, a second type of demodulation for the set of codewords, or both. The UE may receive, based on transmitting the first report, the set of codewords over a set of spatial streams in accordance with the per codeword demodulation or the second type of demodulation. The UE may transmit a second report indicating a capacity ratio metric for each codeword of the set of codewords based on receiving the set of codewords over the set of spatial streams in accordance with the per codeword demodulation or the second type of demodulation.
