Abstract

The invention discloses a method and apparatus in a node used for wireless communication. A first node receives a first information block and a first signaling, and operates a first signal. The first information block is used for determining M first-class indexes from N first-class indexes; the M first-class indexes are used for determining M1 information elements from N1 information elements and determining M2 information elements from N2 information elements; the first signaling comprises scheduling information of the first signal, and a first information element is used for determining a receiving / sending parameter of the first signal; when the operation is receiving, the first signaling indicates the first information element from the M1 information elements; when the operation is transmitting, the first signaling indicates the first information element from the M2 information elements. According to the method, beam management is simplified, and uplink data transmission performance is improved.

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] Multi-antenna technology is a key technology in 3GPP (3rd Generation Partner Project, 3rd Generation Partner Project) LTE (Long-term Evolution, long-term evolution) system and 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, sending and receiving nodes) / panels (antenna panels), additional diversity gain can be obtained by utilizing the spat...
