Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive a plurality of downlink transmissions from a base station. The UE may identify a channel state information (CSI) trigger event. The UE may transmit an accumulated CSI report comprising CSI for each downlink transmission of the plurality of downlink transmissions in accordance with the CSI trigger event, wherein a quantization level of the CSI for each downlink transmission in the accumulated CSI report is based at least in part on a time between the downlink transmission and the CSI trigger event.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify one or more antenna groups at the UE, each of the one or more antenna groups comprising two or more antenna ports and associated with group-based sounding reference signal transmission. The UE may receive an indication of a sounding reference signal configuration identifying one or more resources for performing group-based sounding reference signal transmissions using at least one of the one or more antenna groups. The UE may transmit one or more sounding reference signals using the one or more resources and at least one antenna port from the at least one of the one or more antenna groups.

Abstract: A user equipment may be configured to assist channel reconstruction using partial spatial sounding. In some aspects, the user equipment (UE) may transmit, to another device, correlation capability information indicating a sounding reference signal (SRS) grouping capability of the UE, and receive, from the other device, reference signal (RS) configuration information for configuring a sounding procedure to be performed by the UE. Further, the UE may transmit a reference signal to the other device over a reference antenna port of the UE to allow the other device to determine channel information for another antenna port of the UE, and receive data from the other device based on the channel information.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a capability message indicating a first number of one or more transmit antennas supported by the UE for antenna switching and a second number of ports supported for uplink transmission that exceeds the first number of one or more transmit antennas. The UE may receive, based on the capability message, a sounding reference signal (SRS) configuration indicating a mapping between each SRS resource or SRS resource group and a respective bit sequence of a set of bit sequences. The UE may receive a control message comprising one or more bit sequences of the set of bit sequences indicating one or more SRS resources or an SRS resource group based on the mapping. The UE may transmit one or more SRS signals based on the control message.

Abstract: Aspects relate to configuring active groups of antenna ports. An apparatus may support different groups of antenna ports. One or more of these groups may be designated as active (e.g., for a scheduled transmission). In some examples, a first apparatus may send to a second apparatus an indication of the active groups. The second apparatus may then use the active groups for a transmission.
