Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. A first node receives a first information block and receives Q1 first type signals in Q1 first type time-frequency resource sets. Wherein the first data block is used for generating the Q1 first type signals; the first information block is used for determining Q2 transmission configuration parameters, the Q2 transmission configuration parameters are jointly used for receiving the Q1 first-class signals, and the first signal is one of the Q1 first-class signals; the first reference signal is one of the Q2 first type reference signals; the first signal and the first reference signal have a first-class relationship, and the position of the first signal in the Q1 first-class signals is used for determining the first reference signal from the Q2 first-class reference signals. Through the method provided by the invention, the Doppler frequency shift resistance in a scene of multiple sending and receiving nodes can be enhanced.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, especially a wireless signal transmission method and device 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 put forward different performance requirements for the system. In order to meet the different performance requirements of various application scenarios, the new air interface technology (NR, New Radio) (or Fifth Generation, 5G) to conduct research, passed the WI (Work Item, work item) of NR at the 3GPP RAN#75 plenary meeting, and started to standardize NR. [0003] The multi-antenna technology is a key technology in a 3GPP (3rd Generation Partner Project, third generation partnership project) LTE (Long-term Evolution, long-term evolution) system and an NR ...
