Abstract: Certain aspects of the present disclosure provide techniques for a channel state information (CSI) report configuration for a multiple transmission reception point (TRP) transmission, such as a non-coherent joint transmission (NCJT). A method by a base station (BS) includes providing a user equipment (UE) with a CSI report configuration. The CSI report configuration is associated with one or more CSI reference signal (RS) resources. Each CSI-RS resource comprising a set of ports or port groups. The BS signals the UE to enable the UE to send a CSI report including CSI for more than one CSI-RS resource or for a CSI-RS resource comprising more than one port group and receives a CSI report from the UE.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing uplink control information (UCI) on physical uplink control channel (PUCCH) resources for non-ideal backhaul based multi-transmission/reception point non-coherent joint transmissions. An example method generally includes determining that a first set of physical uplink control channel (PUCCH) resources configured for reporting channel state information (CSI) overlaps with a second set of PUCCH resources indicated for reporting hybrid automatic repeat request (HARQ) feedback, wherein the first and second sets of PUCCH resources are associated with downlink demodulation reference signal (DMRS) port groups, generating CSI reports and HARQ feedback associated with at least one of the downlink DMRS port groups, and transmitting the CSI reports and the HARQ feedback, multiplexed using the second set of PUCCH resources.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to rate matching for new radio (NR) physical downlink shared channel (PDSCH) and physical uplink shared channel (PUSCH). In certain aspects, a method includes receiving a rate matching resource (RMR) configuration from a serving cell. The method also includes identifying one or more first resource elements (REs) to be rate matched around at least in part based on a transmission numerology associated with the RMR configuration, wherein the one or more first REs are used for reference signal (RS) transmission in the serving cell or a neighboring cell. The method further includes mapping a physical downlink shared channel (PDSCH) to one or more second REs not including the first REs.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first message indicating a UE capability to perform antenna-switching using a zero-delay gap period between successive transmissions of a sounding reference signal (SRS) using different antennas of the UE. The UE may receive a second message indicating a set of SRS parameters for the UE, the set of SRS parameters based at least in part on the UE capability. The UE may perform the successive transmissions of the SRS using the zero-delay gap period between the successive transmissions of the SRS according to the set of SRS parameters.

Abstract: Techniques and devices for wireless communications are described. A user equipment (UE) may receive a configuration from a network entity for multiplexing a reference signal with a data signal in time and in frequency or for multiplexing the reference signal in a Doppler domain. The UE may receive an assignment of multiple time-frequency resources from the network entity for transmission of the reference signal. The UE may multiplex the reference signal across the assigned time-frequency resources in accordance with the received configuration. The UE may transmit the multiplexed reference signal to the network entity.

Abstract: A user equipment (UE) may report capabilities pertaining to UE feedback processing, such as a number of simultaneous feedback reports that can be processed and reported by the UE for various types of feedback. For example, UE feedback processing capability may depend on channel state information (CSI) processing units (CPUs) available to the UE for feedback processing operations (e. g., for performing channel measurements, processing feedback, generating a feedback report, etc.). A UE may report feedback processing capability separately for periodic feedback reporting and for aperiodic feedback reporting, for different types of feedback reporting (e. g., for CSI reporting, for beam management reporting, etc.), etc. As such, a UE may more efficiently report capabilities pertaining to UE feedback processing, and a base station may more efficiently configure UE feedback reporting according to UE feedback processing capability.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, devices use machine learning (ML) models to support wireless communications. For example, a user equipment (UE) may download ML model information from a network to determine an ML model. The network may additionally configure a status reporting procedure, a fallback procedure, or both for the ML model. In some examples, based on a configuration, the UE may transmit a status report to a base station according to a reporting periodicity, a UE-based trigger, a network-based trigger, or some combination thereof. Additionally or alternatively, the UE may determine to fallback from operating using the ML model to operating in a second mode based on a fallback trigger. In some examples, to restore operating using a downloaded ML model, the UE may download an updated ML model or receive iterative updates to a previously downloaded ML model.
