Abstract
Certain aspects of the present disclosure provide techniques for a beam refinement procedure. According to certain aspects, a method for wireless communications by a receive node generally includes receiving, from a transmit node, a configuration indicating channel state information reference signal (CSI-RS) resources and an indication of at least one receive beam for the receive node to use for measuring CSI-RS transmitted on the CSI-RS resources and transmitting, to the transmit node, a report indicating a value generated using a function that combines measurements taken on the CSI-RS resources.

A method for wireless communications by a receive node, comprising:
- receiving, from a transmit node, a configuration indicating channel state information reference signal (CSI-RS) resources and an indication of at least one receive beam for the receive node to use for measuring CSI-RS transmitted on the CSI-RS resources;
- and
- transmitting, to the transmit node, a report indicating a value generated using a function that combines measurements taken on the CSI-RS resources.
A method for wireless communications by a transmit node, comprising:
- transmitting, to a receive node, a configuration indicating channel state information reference signal (CSI-RS) resources and an indication of at least one receive beam for the receive node to use for measuring CSI-RS transmitted on the CSI-RS resources;
- transmitting CSI-RS to the receive node on the CSI-RS resources;
- and
- receiving, from the receive node, a report indicating a value that represents a combination of measurements taken by the receive node on the CSI-RS resources.
An apparatus, comprising:
- a memory comprising executable instructions;
- and
- one or more processors configured to execute the executable instructions and cause the apparatus to:
- receive, from a transmit node, a configuration indicating channel state information reference signal (CSI-RS) resources and an indication of at least one receive beam for the apparatus to use for measuring CSI-RS transmitted on the CSI-RS resources, and
- transmit, to the transmit node, a report indicating a value generated using a function that combines measurements taken on the CSI-RS resources.
