METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING DOWNLINK CHANNEL FROM MULTIPLE TRANSMISSION RECEPTION POINTS IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18357630 titled 'METHOD AND DEVICE FOR TRANSMITTING OR RECEIVING DOWNLINK CHANNEL FROM MULTIPLE TRANSMISSION RECEPTION POINTS IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
This patent application describes a method and device for transmitting and receiving a downlink channel in a wireless communication system.
- The method involves a terminal repeatedly receiving a downlink control channel that contains the same downlink control information (DCI) from one or more transmission reception points (TRPs).
- The DCI includes control information related to downlink signal reception, and the terminal uses this information to determine the time offset between a specific transmission occasion (TO) and the receiving timing of the downlink signal.
- If the time offset is less than a predetermined threshold, the terminal receives the downlink signal from a single TRP based on a default transmission configuration indicator (TCI) state.
- The default TCI state is related to a search space set or a control resource set (CORESET) with the lowest identifier in the latest slot that the terminal monitors.
Original Abstract Submitted
A method and a device of transmitting or receiving a downlink channel from multiple transmission and reception points in a wireless communication system is disclosed. A method of receiving a downlink signal by a terminal in a wireless communication system according to an embodiment of the present disclosure may include repeatedly receiving a downlink control channel including same downlink control information (DCI) in at least one transmission occasion (TO) from at least one transmission reception point (TRP); and based on the DCI including control information related to downlink signal reception, based on a time offset between a specific TO of the at least one TO and a receiving timing of a downlink signal related to the DCI being less than a predetermined threshold, receiving the downlink signal from a single TRP based on a default transmission configuration indicator (TCI) state and the default TCI state may be a TCI state related to a search space set or a control resource set (CORESET) having a lowest identifier in a latest slot that the terminal monitors.
