Abstract: This disclosure provides methods, devices and systems for channel sounding for wireless communications. Some implementations more specifically relate to scheduling sounding reference signal (SRS) resource sets for wireless devices having more than 4 receive (RX) antenna ports. In some implementations, a base station may determine an antenna switching capability of a user equipment (UE). The antenna switching capability indicates a number of RX antenna ports of the UE. The base station schedules a number of SRS resource sets for the UE based at least in part on the number of RX antenna ports in excess of four. For example, the number of RX antenna ports may be equal to 8. As another example, the number of RX antenna ports may be equal to 6. The base station further receives, from the UE, uplink transmissions of one or more SRS resources for each of the scheduled SRS resource sets.

Abstract: Methods, systems, and devices for wireless communications are described for configuration and transmission of one or more uplink reference signals for tracking. A user equipment (UE) may transmit one or more uplink reference signals for tracking and a base station or transmission-reception point (TRP) may estimate one or more frequency or time shifts (e.g., a Doppler shift, time shift, or both) associated with communications with the UE. The estimated frequency shifts, time shifts, or combinations thereof, may be used to provide compensated communications (e.g., Doppler compensated communications) with the UE. The uplink reference signal for tracking may be a sounding reference signal that is configured as a tracking reference signal.

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, a radio resource control (RRC) configuration with one or more high layer parameters that enable one or more of an aperiodic sounding reference signal (SRS) triggering without data scheduling or a secondary cell (SCell) dormancy indication using downlink control information (DCI). The UE may receive, from the base station and based at least in part on the RRC configuration, DCI that is associated with at least one of: the aperiodic SRS triggering without data scheduling or the SCell dormancy indication. The UE may transmit, to the base station, an aperiodic SRS based at least in part on the DCI that triggers the aperiodic SRS. Numerous other aspects are described.

Abstract: A first device may transmit an indication of a base graph recommendation. A second device may receive the indication of the base graph recommendation. The second device may select a base graph from a plurality of base graphs based on the base graph recommendation. The second device may transmit an indication of the selected base graph from the plurality of base graphs after the selection of the indication of the base graph recommendation. The first device may receive the indication of the selected base graph from the plurality of base graphs after an output of the indication of the base graph recommendation. The second device may transmit a low density parity check (LDPC) coded transmission based on the selected base graph. The first device may receive the LDPC coded transmission based on the selected base graph.

Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE receives first signaling triggering the UE to transmit a base channel state information (CSI) report to a network entity. The UE transmits the base CSI report to the network entity in response to the first signaling. The UE takes action to reduce or avoid error propagation when transmitting one or more differential CSI reports that include at least some CSI values reported relative to CSI values in the base CSI report.

Abstract: Aspects of the disclosure relate to transmission of a single CSI report that includes time domain channel information obtained from a plurality of CSI-RSs received by a UE over time. For example, each of the CSI-RSs may be associated with a different respective time resource (e.g., each CSI-RS is received at a different respective time). The UE may obtain a plurality of CSI values based on the plurality of CSI-RSs and generate the time domain channel information from the plurality of CSI values. In some examples, the time domain channel information includes the plurality of CSI values. In other examples, the time domain channel information includes compressed channel information based on the plurality of CSI values. A base station may then utilize the time domain channel information included in the CSI report for scheduling downlink data transmissions to the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, control signaling indicating a configuration for use by the UE to select one or more of a plurality of resource sets for a bandwidth part (BWP) for the UE, where each of the resource sets comprise reference signal resources that correspond to one or more antenna ports of the UE. The UE may receive, from the base station, an activation message instructing the UE to activate at least one resource set of the plurality of resource sets for reference signal transmission using the BWP. The UE may transmit a reference signal over the activated resource set using the BWP and at least one antenna port of the one or more antenna ports based at least in part on the activation message, the antenna port corresponding to the activated resource set.

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.
