Title:
NON-PERIODIC CHANNEL STATE INFORMATION TRIGGERING AND REPORTING IN WIRELESS COMMUNICATIONS
Document Type and Number:
WIPO Patent Application WO/2019/192013
Kind Code:
A1
Abstract:
Methods, systems, and devices for wireless communications are described that support non-periodic channel state information (CSI) triggering and reporting in wireless communications. In cases where two or more CSI report requests trigger multiple CSI report transmissions in an same uplink slot, a user equipment (UE) may format at least a subset of the multiple CSI reports according to a formatting configuration for transmission of multiple CSI reports in a same uplink slot. The UE may use allocated resources in the uplink slot for each CSI report that are allocated by the base station in the corresponding CSI report request. In some cases, the UE may combine the multiple CSI reports, or parts thereof, into a combined CSI report that may be transmitted using allocated resources of one of the CSI report requests.
