Abstract
Certain aspects of the present disclosure provide techniques for a UE-based CSI reporting request. In some cases, upon detecting a condition indicative of a change in channel conditions, a UE sends a request for CSI reporting.
Claims30
A method for wireless communications by a user equipment (UE), comprising:
- detecting a condition indicative of a change in channel conditions;
- sending an indication to a network entity to initiate channel state information (CSI) reporting by the UE, based on the detection;
- monitoring for a downlink transmission from the network entity to trigger CSI reporting;
- monitoring for CSI reference signals (CSI-RS) from the network entity;
- and
- sending a CSI report based on the CSI-RS.
3 more elements
A method for wireless communications by a network entity, comprising:
- receiving an indication, from a user equipment (UE), to initiate channel state information (CSI) reporting by the UE;
- sending a downlink transmission, after receiving the indication, to trigger CSI reporting by the UE;
- transmitting CSI reference signals (CSI-RS);
- and
- receiving, from the UE, a CSI report based on the CSI-RS.
