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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a first network device using a first communication technology, an indication of a resource mapping between a first set of time resources for downlink communications using the first communication technology and a second set of time resources for downlink communications using a second communication technology. The UE may determine a timing for receiving a first message from a second network device using the second communication technology based on receiving the indication of the resource mapping. The UE may receive, from the second network device, the first message using the second communication technology based on determining the timing. The UE may transmit, to the first network device, a second message including feedback information using the first communication technology based on receiving the first message from the second network device using the second communication technology.

Abstract: Methods, systems, and devices for wireless communications are described for closed-loop precoding for multiple-input multiple-output for transmitter circle arrays, for example uniform circular array panels. In some aspects, a base station including a transmitter circle array may steer a beam to a user equipment (UE) using codebooks, quantization rules, and feedback from the user equipment. In some aspects, the same transmitter circle array may be used for both backhaul communications with a device at a fixed location, for example using beams formed via discrete Fourier transform (DFT) vectors, and access communications with a UE via non-DFT beams coded using closed-loop precoding.

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) includes receiving a CSI report configuration for frequency domain compressed precoder matrix feedback. The CSI report configuration configures the UE 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. For each of the beams, the UE 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. The UE quantizes the corresponding linear combination coefficients and/or frequency domain compression basis vectors based on the grouping.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify that a set of resources to be used for reception of a synchronization signal block (SSB) overlaps at least one of a set of resources to be used for a first uplink transmission or a set of resources to be used for a second uplink transmission. The set of resources to be used for the first uplink transmission may overlap the set of resources to be used for the second uplink transmission. The first uplink transmission and the second uplink transmission may have a same priority index value. The UE may resolve an overlap between the first uplink transmission and the second uplink transmission and then resolve an overlap associated with the reception of the SSB. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, an indication that the base station supports visible light communication (VLC). The UE may deactivate a radio frequency (RF) receiver of the UE based on the indication, and may receive a VLC message at a photo detector of the UE while the RF receiver of the UE is deactivated. In some examples, the UE may activate the RF receiver based on a content of the VLC message, which may include a physical cell identifier (PCI), a UE identifier, or a system information value tag, among other examples. Accordingly, the UE may communicate with the base station using the RF receiver. The described techniques may provide for reduced power consumption at the UE, among other benefits.
