METHOD AND APPARATUS OF TCI STATE INDICATION AND UPDATE VIA DYNAMIC SIGNALING - A simplified explanation of the abstract
This abstract first appeared for US patent application 18308983 titled 'METHOD AND APPARATUS OF TCI STATE INDICATION AND UPDATE VIA DYNAMIC SIGNALING
Simplified Explanation
This patent application describes methods and apparatuses for indicating and updating transmission configuration in a wireless communication system. Here are the key points:
- The invention focuses on transmission configuration indication (TCI) state indication and update in a wireless communication system.
- The method involves a user equipment (UE) receiving indicators in radio resource control (RRC) signaling and medium access control (MAC) control element (CE).
- The UE also receives scheduling information of a physical downlink shared channel (PDSCH) to determine the appropriate TCI state.
- The first indicator helps identify different groups of TCI states, while the second indicator determines whether a TCI state needs to be updated.
- Based on the identification and the second indicator, the method determines whether the TCI states belong to the first or second group of TCI states.
Original Abstract Submitted
Methods and apparatuses for transmission configuration indication (TCI) state indication and update via dynamic signaling in a wireless communication system. A method performed by a user equipment (UE) includes receiving, in a radio resource control (RRC) signaling, a first indicator; receiving, in a medium access control (MAC) control element (CE), a second indicator; receiving scheduling information of a physical downlink shared channel (PDSCH); and receiving, based on a first or second applied TCI state, the PDSCH. The method further includes identifying, based on the first indicator, at least one of a first group or a second group of TCI states; determining, based on the second indicator, whether a first or second TCI state updates the first or second applied TCI state; and determining, based on the identification and the second indicator, whether the first and second TCI states belong to the first group or second group of TCI states.
