Title:
APPARATUS AND METHOD OF TCI STATES CONFIGURATION AND ACTIVATION OR DEACTIVATION
Document Type and Number:
WIPO Patent Application WO/2021/035423
Kind Code:
A1
Abstract:
Apparatus and methods of Transmission Configuration Indication (TCI) states configuration and activation or deactivation for multiple DCI (M-DCI) based multiple TRP (M-TRP) Downlink (DL) transmission are disclosed. The apparatus includes: a receiver that receives a capability report from a remote device, wherein the capability report indicates that the remote device supports 128 or more configurable TCI states; a processor that configures 128 or more TCI states according to the capability report; and a transmitter that transmits a Media Access Control (MAC) Control Element (CE) to activate a subset of the TCI states.
