Abstract: A user equipment (UE) may be configured to transmit sounding reference signals to sound over ports of a channel. The UE may be configured to receive a message to trigger transmission of at least one sounding reference signal (SRS) of at least one SRS resource set for sounding over an active bandwidth part (BWP) in an upcoming slot, the upcoming slot being offset by a number of available slots from a reference slot indicated by the message. The UE may be further configured to detect a gap in which operation for the active BWP is suspended occurring before the transmission of the at least one SRS of the at least one SRS resource set is complete.

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: Certain aspects of the present disclosure relate to methods and apparatus for flexibly setting subband CSI-related parameters. An example method includes receiving signaling indicating partial band settings for one or more bandwidth parts within a system bandwidth, wherein each bandwidth part includes a set of physical resource blocks (PRBs), wherein the bandwidth part is a part of the system bandwidth, receiving partial band channel state information (CSI) reference signal (RS) settings for one or more partial bands within a system bandwidth for CSI-related processing, wherein each partial band includes a set of PRBs, wherein the partial band is a part of the bandwidth part, receiving partial band CSI reference signals (CSI-RS) from at least one at least one (BS), transmitting CSI-reporting to the at least one BS, in accordance with the partial band CSI-RS settings, communicating with the at least one BS in accordance with the partial band settings.

Abstract: Methods, systems, and devices for wireless communications are described. A reconfigurable reflective surface may exploit signals transmitted from a user equipment (UE) to communicate feedback to a base station. For example, the surface may communicate feedback by reflecting two or more reference signals according to two or more configurations. In some cases, the two or more configurations may be phase shifted relative each other. In another example, the surface may communicate feedback by altering the intensity of or more reference signals transmitted from the UE. In yet another example, the surface may communicate feedback to the base station by reflecting reference signals towards one or more antenna arrays. In some cases, the one or more antenna arrays may be located at a single base station. In some other cases, the one or more antenna arrays may be located at multiple base stations or multiple transmission/reception points.
