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: Methods, systems, and devices for wireless communications are described. In some systems, a base station may transmit a slot format indicator (SFI) to a first user equipment (UE) via downlink control information (DCI) and the first UE may use the SFI to determine time-domain resources over which the first UE may measure cross link interference (CLI) arising from a transmission from a second UE. The first UE may use the SFI as an index into a slot format combination table, which may also be used for uplink and downlink scheduling or may be exclusively used for determining the time-domain resources for CLI measurement. The first UE may determine a set of slot formats from a slot format table based on a slot format combination corresponding to the SFI index and may determine over which symbols the first UE may measure CLI based on the set of slot formats.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a demodulation reference signal (DMRS) configuration for a periodic reporting of a joint DMRS and channel state feedback (CSF) report to a base station based on a channel state information (CSI) reference resource and related definitions and assumptions. The UE may identify a CSI reference resource slot for dynamically determining one or more parameters associated with the DMRS configuration. The UE may calculate the one or more components of the CSF report based on the DMRS configuration and may transmit the components to the base station in the CSF report or the joint DMRS and CSF report if additional indication of the recommended DMRS configuration is included in the report based on a report configuration.

Abstract: Aspects of the present disclosure provide techniques for physical uplink shared channel transmissions sent using multiple frequency domain resource allocations (FDRAs). According to certain aspects, a user equipment (UE) determines at least a first part frequency domain resource allocation (FDRA) and a second part FDRA, transmits a first part of a physical uplink shared channel (PUSCH) on the first part FDRA with a first precoder, and transmits a second part of the PUSCH on the second part FDRA with a second precoder.
