METHODS FOR NON-PMI CSI REPORTING ENHANCEMENTS FOR MULTI-TRP OPERATION

Title:

METHODS FOR NON-PMI CSI REPORTING ENHANCEMENTS FOR MULTI-TRP OPERATION

Document Type and Number:

WIPO Patent Application WO/2023/044720

Kind Code:

A1

Abstract:

Apparatuses, systems, and methods for enhancing non-PMI based CSI reporting for NC-JT in multi-TRP operations, including addressing channel CRI reporting, CQI reporting, RI reporting, and CSI processing complexity and timeline in NC-JT multi-TRP operations. For example, a UE may receive, from a base station, a configuration for a first set of CSI-RS resources for a first TRP (associated with single TRP operation), a second set of CSI-RS resources for a second TRP (associated with single TRP operation), and a third set of pairs of CSI-RS resources for the first TRP and second TRP (associated with multi-TRP operation). The UE may report, to the base station, a CRI report indicating whether the UE prefers single TRP operation from the first TRP or the second TRP, or multi-TRP operation from the first TRP and the second TRP. The CRI report may be based on the configuration.
