Title:
METHOD USED IN NODE FOR WIRELESS COMMUNICATION, AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/078373
Kind Code:
A1
Abstract:
Disclosed in the present application are a method used in a node for wireless communication, and an apparatus. A first node receives a first information block and a second information block, and receives a first wireless signal in a first time-frequency resource set; the first information block is used for determining a first transmission configuration parameter group, the first transmission configuration parameter group comprising a plurality transmission configuration parameters; the plurality of transmission configuration parameters are respectively used for determining a plurality of reference signals, and a first reference signal is one among the plurality of reference signals; a first type of relationship exists between the first wireless signal and the first reference signal, and a second type of relationship exists between the first wireless signal and a reference signal among the plurality of reference signals excluding the first reference signal, the first type of relationship and the second type of relationship being different; and a first time threshold is used for determining the first reference signal. Anti-doppler shift performance in a multi-transmitter receiver point scenario can be enhanced by means of the method in the present application.
