Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. The first node receives the first information block; a first type of signaling is monitored with a target spatial relationship in a first set of resources in a first time window. The first information block is used for determining a first spatial relationship, the first spatial relationship is one of K spatial relationships, and K is a positive integer greater than 1; the target spatial relationship is one of the K spatial relationships; the first information block is used for determining a first moment, a time interval between the first moment and the first time window is a first interval, and the first spatial relationship and the first interval are jointly used for determining the target spatial relationship from the K spatial relationships. According to the method, the gain of beamforming is kept in a high-speed mobile environment, and the communication quality is improved.

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 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 (New Radio, new radio) system. Additional spatial degrees of freedom are obtained by configuring multiple antennas at a communication node, such as a base station or a UE (User Equipment, User Equipment). Multiple antennas use beamforming to form beams pointing in a specific direction to improve communication quality. When multiple antennas belong to multiple TRPs (Transmitter Receiver Points, transmitting and receiving nodes) / panels (antenna panels), an additional diversity gain can be obtained by utilizi...
