METHOD AND APPARATUS FOR CONFIGURING A UNIFIED TCI STATE - A simplified explanation of the abstract

This abstract first appeared for US patent application 17937363 titled 'METHOD AND APPARATUS FOR CONFIGURING A UNIFIED TCI STATE

Simplified Explanation

The patent application describes methods and apparatuses for configuring a unified transmission configuration indicator (TCI) state in a wireless communication system. The method involves receiving configuration information for a list of TCI states, a control resource set (CORESET), and a search space set associated with the CORESET. The method also includes receiving an indication of a TCI state for the list of TCI states. Based on the received information, the method identifies the type of the search space set and the index of the CORESET. The indicated TCI state is then applied to a physical downlink control channel (PDCCH) in the CORESET, considering the identified type and index or additional configuration information. The PDCCH is received based on quasi-co-location properties corresponding to the indicated TCI state.

Original Abstract Submitted

Methods and apparatuses for configuration of unified transmission configuration indicator (TCI) state in a wireless communication system. A method of operating a user equipment (UE) includes receiving configuration information for a list of TCI states for downlink (DL) or joint TCI states, receiving configuration information for a control resource set (CORESET), receiving configuration information for a search space set associated with the CORESET, and receiving an indication of a TCI state for the list of TCI states. The method further includes identifying a type of the search space set and an index of the CORESET, applying the indicated TCI state to a physical downlink control channel (PDCCH) in the CORESET based on (i) the identified type of the search space set and the identified index of the CORESET or (ii) additional configuration information, and receiving the PDCCH based on quasi-co-location properties corresponding to the indicated TCI state.
