Abstract: This disclosure provides systems, methods and apparatus for wireless communications. In one aspect, a device, such as a user equipment (UE) may receive a configuration including one or more channel state information (CSI) measurement resources associated with a set of CSI hypotheses. The set of CSI hypotheses may correspond to a set of transmission configuration indicator (TCI) states, or a CSI interference measurement (CSIIM) resource, or both. The UE may select a first CSI measurement resource of the one or more CSI measurement resources for a channel measurement based on a CSI hypothesis of the set of CSI hypotheses. The UE also may select the CSIIM resource or a second CSI measurement resource for an interference measurement based on the CSI hypothesis of the set of CSI hypotheses. The UE may, as a result, transmit a report based on the channel measurement or the interference measurement, or both.

Abstract: Methods, systems, and devices are described for wireless communications that support transmitting channel state information (CSI) feedback utilizing flexible uplink control resources. A method may include determining a size of a frequency subband corresponding to components of a CSI feedback report based on configuration signaling or a size of allocated uplink control resources. A method may include encoding a CSI report into a single packet and transmitting the single packet over uplink control resources. A method may include encoding a first plurality of components of a CSI report in a first packet, encoding a second plurality of components of the CSI report in a second packet, and mapping the packets to uplink control resources. A method may include transmitting a first plurality of components of a CSI report on a first slot and a second plurality of components of the CSI report on one or more subsequent slots.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that configures a reference signal (RS) transmission with a repetition factor, wherein the configuration information indicates one or more parameters for the RS transmission including at least one of: a sequence hopping configuration associated with the RS transmission, a cyclic shift offset configuration associated with the RS transmission, or a frequency hopping configuration indicating subcarrier hopping across adjacent RS symbols. The UE may perform the RS transmission using the repetition factor in accordance with the configuration. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of one or more of an input size or an input structure for a transmitting-side neural network, wherein the input structure indicates one or more of non-zero values or locations for the non-zero values within an input, having the input size, to the transmitting-side neural network. The UE may communicate with a base station based at least in part on the indication of the one or more of the input size or the input structure of the transmitting-side neural network. Numerous other aspects are provided.

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, downlink control information (DCI) that triggers one or more aperiodic sounding reference signal (SRS) resource sets. The UE may determine that a candidate slot is an available slot associated with the one or more aperiodic SRS resource sets based at least in part on available information at a timestamp of the candidate slot, and one or more of a radio resource control (RRC) configuration or dynamic event information. The UE may transmit, to the base station, an aperiodic SRS using the one or more aperiodic SRS resource sets of the available slot. Numerous other aspects are described.

Abstract: Example implementations include a method, apparatus and computer-readable medium of wireless communication to be performed by a user equipment (UE), comprising receiving, from a base station, a synchronization signal block (SSB) via a reconfigurable intelligent surface (RIS), the SSB corresponding to a first SSB type configured for RIS-assisted procedures. The implementations further include performing, with the base station according to the SSB, a random access channel (RACH) procedure. Additionally, the implementations further include transmitting, to the base station according to the SSB, an indication that the SSB corresponds to the first SSB type as part of the RACH procedure.
