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.

Abstract: Certain aspects of the present disclosure provide techniques for determining a timing advance (TA) for a handover in a network, such as a non-terrestrial network, A method that may be performed the UE includes receiving, from a source base station (BS), a handover command instructing the UE to hand over to a target BS, obtaining an indication of a timing advance (TA) for communicating with the target BS, wherein the indication of the TA for communicating with the target BS is based, at least in part, on a TA used for communicating with the source BS and a first time difference between a first reference signal associated with the source BS and a second reference signal associated with the target BS, and transmitting, based on the handover command, one or more signals to the target BS using the TA for communicating with the target BS.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may determine that a distance between an end of a first downlink control information (DCI) and a corresponding first physical downlink shared channel (PDSCH) and a distance between an end of a second DCI and a corresponding second PDSCH satisfy a minimum distance threshold for a user equipment (UE). The ends of the DCIs are to be received at the same symbol. The base station may transmit the first DCI, the first PDSCH, the second DCI, and the second PDSCH based at least in part on determining that the distances satisfy the minimum distance threshold. In some aspects, the UE may decode the first and second DCIs in an order that depends on DCI properties. Numerous other aspects are provided.

Abstract: A user equipment (UE) (e.g., an enhanced machine type communication (EMTC) UE) may identify several narrowbands associated with eMTC protocol based on a system bandwidth of a New Radio (NR) carrier. A base station may transmit an indication of a set of valid narrowbands for eMTC (e.g., based on coexistence considerations between eMTC and NR) to the UE. The base station may further transmit a frequency hopping pattern to the UE (e.g., associated with narrowbands within the set of valid narrowbands), and transmit one or more downlink transmissions according to the frequency hopping pattern. Additionally or alternatively, a base station may identify a subcarrier offset and/or resource block offset between resources (e.g., a resource grid) used for eMTC protocol and resources used for NR. The base station may transmit a frequency alignment parameter to the UE, and the UE may align narrowbands for eMTC accordingly.

Abstract: A method of wireless communication by a user equipment (UE) in a non-terrestrial network (NTN) includes transmitting a first small data transmission to a base station during a first transmission occasion associated with a first NTN beam, while the UE remains in an inactive mode or idle mode. The method further includes identifying a switch from the first NTN beam to a second NTN beam. The method still further includes transmitting a subsequent small data transmission to the base station during a second transmission occasion associated with the second NTN beam.
