    Abstract: Methods, systems, and devices for wireless communications are described. A bandwidth reduced low-tier user equipment (UE) may receive a signal identifying a control resource set for the UE to monitor for control information scheduling communications between the UE and a base station, the control resource set comprising a plurality of control channel elements organized across more than three symbols and comprising one or more first resource element groups mapped to a first monitoring occasion and one or more second resource element groups mapped to a second monitoring occasion. The UE may receive, during the first monitoring occasion, at least a first portion of the control information on the one or more first resource element groups. The UE may receive, during the second monitoring occasion, at least a second portion of the control information on the one or more second resource element groups. The UE may communicate with the base station in accordance with the control information.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may receive a sub-band specific sounding reference signal (SRS) resource indicator identifying subsets of SRS resources, of a set of SRS resources, associated with precoding a physical uplink shared channel (PUSCH) communication that is to be transmitted in a PUSCH resource. The user equipment may precode the PUSCH communication based at least in part on the sub-band specific SRS resource indicator. The user equipment may transmit the PUSCH communication after precoding the PUSCH communication based at least in part on the sub-band specific SRS resource indicator. Numerous other aspects are provided.

    Abstract: Certain aspects of the present disclosure provide techniques for channel state information (CSI) reporting with frequency domain (FD) compression. A method that can be performed by a user equipment (UE) includes determining the size of the intermediate set based on one or more parameters included in the CSI report configuration, determining one or more FD bases for each layer based on the intermediate set, wherein the one or more FD bases are characterized by an M value indicative of a number of the one or more FD bases and based on the CSI report configuration, and reporting the one or more FD bases for each layer based on the size of the intermediate set.

    Abstract: Certain aspects of the present disclosure provide techniques for precoder matrix quantization for compressed channel state information (CSI) feedback. A method for wireless communications by a user equipment (UE) (120a) includes receiving a CSI report configuration for frequency domain compressed precoder matrix feedback. The CSI report configuration configures the UE (120a) to report, for a plurality of selected beams at a plurality of time domain taps, a frequency domain compression basis vector and a plurality of linear combination coefficients associated with the frequency domain compression (805). For each of the beams, the UE (120a) groups the time domain taps into at least first and second groups. The groups each can have zero, one, or more than one time domain taps (810). The UE (120a) quantizes the corresponding linear combination coefficients and/or frequency domain compression basis vectors based on the grouping (815).

    Abstract: Dynamic reconfiguration of CSI-RS resources for CSI reporting is described for full dimension multiple input, multiple output (FD-MIMO) systems. While a larger number of channel state information (CSI) reference signal (CSI-RS) resources with independent resource configuration are configured and associated with a CSI process, only a subset of resources that are activated by additional signaling are used for CSI measurement and reporting. The set of activated CSI-RS resources may include only a single CSI-RS resource. Both periodic and aperiodic CSI reporting may then be based on the same set of the activated CSI-RS resources. Medium access control (MAC) control elements may be used to provide activation/deactivation of the CSI-RS resources. Additionally, CSI reporting may be based on both the activated CSI-RS resources and the associated number of antenna ports.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine a first decoding result for a plurality of downlink control channels of a diversity enhancement based non-coherent joint transmission communication and a second decoding result for a plurality of data channels corresponding to the plurality of downlink control channels; and selectively provide feedback regarding the first decoding result and feedback regarding the second decoding result, the feedback regarding the first decoding result indicating whether reception of one or more downlink control channels, of the plurality of downlink control channels, is successful, and the feedback regarding the second decoding result indicating whether decoding of a codeword of the plurality of data channels is successful.
