Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit, to a base station, a control message indicating a capability of the UE to identify and report a reciprocity parameter between downlink communications and uplink communications of a channel between the UE and the base station. In some examples, the base station may request a reciprocity report from the UE. The UE may identify a reciprocity parameter based on one or more parameters associated with an array of antennas at the UE. The reciprocity parameter may indicate a reciprocity between an uplink beam and a downlink beam, such as a degree of overlap between the uplink beam and the downlink beam. The UE may report the reciprocity parameter via a reciprocity report to the base station. In some examples, the base station may identify one or more parameters based on the reciprocity report.

Embodiments of this application disclose a terminal device capability transmission method, apparatus, and system. A terminal device reports, to a network device, capability information used to indicate a channel state information CSI reporting capability of the terminal device. The capability information is associated with a quantity, supported by the terminal device in a time-domain unit, of ports of pilots used for CSI measurement, and is used to enable the network device receiving the capability information to learn the CSI reporting capability of the terminal device, thereby determining a CSI measurement configuration of the terminal device.

Certain aspects of the present disclosure provide techniques for capability information for sounding reference signal (SRS) improvements. An exemplary method generally includes determining a capability of the UE related to additional sounding reference signal (SRS) transmissions in a normal uplink (UL) subframe; transmitting, to a base station (BS), capability information indicating the determined capability of the UE; receiving SRS configuration information, wherein the SRS configuration information is based, at least in part, on the capability information; and transmitting at least one SRS in accordance with the SRS configuration information.
