Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. The first node receives the first information block and receives the first signal in the first time-frequency resource set; wherein the first information block indicates a first transmission configuration parameter and a second transmission configuration parameter, and the first transmission configuration parameter and the second transmission configuration parameter are jointly used for receiving the first signal; the first transmission configuration parameter is used for determining a first reference signal; the second transmission configuration parameter is used for determining a second reference signal and a third reference signal; the second reference signal corresponds to a first type of quasi-co-location relationship, and the third reference signal corresponds to a second type of quasi-co-location relationship; whether a first set of conditions is satisfied is used to determine one of the second reference signal and the third reference signal for receiving the first signal. Through the method provided by the invention, the flexibility of switching among different Doppler frequency shift elimination schemes can be improved, and the overhead and the time delay can be reduced.

Description

technical field [0001] The present application relates to a transmission method and apparatus in a wireless communication system, in particular to a wireless signal transmission method and apparatus in a wireless communication system supporting a cellular network. Background technique [0002] The application scenarios of future wireless communication systems are becoming more and more diversified, and different application scenarios place different performance requirements on the system. In order to meet the different performance requirements of various application scenarios, at the 72nd plenary meeting of RAN (Radio Access Network, Radio Access Network) of 3GPP (3rd Generation Partner Project), it was decided that the new air interface technology (NR, New Radio) (or Fifth Generation, 5G) conducted research, passed the WI (Work Item) of NR at the 3GPP RAN#75 plenary meeting, and began to standardize NR. [0003] Multi-antenna technology is a key technology in 3GPP (3rd Gen...
