Abstract: A network entity can provide a plurality of downlink (DL) transmissions using a plurality of distributed transmission and reception points (TRPs) in a multiple-in-multiple-out (MIMO) system. The network entity can obtain delay metrics of the DL transmissions from the UE. The UE can generate the delay metrics based on measurements of DL reference signals from the distributed TRPs. The network entity can pre-compensate the DL transmissions based on the delay metrics.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a device such as a user equipment (UE), a base station, or both, to perform a channel noise and interference estimation based on a set of null resources in a data channel. The device may identify a first configuration for a set of demodulation reference signals (DMRSs) in a first set of time periods of a data channel and a second configuration for a set of null resources in a second set of time periods of the data channel. The second set of time periods may be nonoverlapping with the first set of time periods. The device may perform a channel estimation procedure on the data channel based on the null resources and the DMRS resources. The device may process data received via resources of the data channel based on the channel estimation procedure.

Abstract: A UE may estimate a CLI channel state based on a ZP-SRS from a second UE. A network node may transmit to the UE, and the UE may receive from the network node, a CSI-RS. The UE may estimate a downlink channel state based on the CSI-RS from the network node. The UE may estimate one or more eCSF parameters based on the CLI channel state, the downlink channel state, two or more interference hypotheses, and at least one of a CPU specification, a timing specification, or a UE capability indication. The UE may transmit to the network node, and the network node may receive from the UE, an eCSF report based on the one or more eCSF parameters.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.

Abstract: Aspects relate to sounding on a subset of available sounding resources. A user equipment (UE) may transmit a sounding reference signal (SRS) on a subset of the frequency resources available for a hop of an SRS hopping sequence. A UE may be configured to use a subset of frequency resources or the UE may autonomously identify this subset. A base station may send a bit map to a UE to indicate the subset of resources to use for a hop. Each bit of the bit map may indicate that the UE is to transmit an SRS on a particular RB or on a particular groups of RBs. The same subset of resources may be designated for each hop or different subsets of resources may be designated for different hops. An indication of the subset of resources may be provided for each hop. The subset of resources may be cycled for different hops.

Abstract: Aspects relate to wireless communication for slot postponing of aperiodic sound reference signals (A-SRS) by a user equipment in a wireless network. A network node, such as a gNodeB, may send at least a portion of a slot postponing configuration for transmission of aperiodic sounding reference signals (A-SRSs) to a user equipment (UE). In a particular aspect, the slot postponing configuration is established through RRC signaling and does not utilize downlink control information (DCI) or MAC-CE sent parameters for establishing the slot postponing configuration. The slot positioning configuration is used to control slot offset postponing, the number of slot offsets, the number of times transmission of A-SRS can be postponed in the UE, and priority rules based on the postponing configuration.
