Abstract

The invention discloses a method and an apparatus in a node used for wireless communication. The method comprises the steps: enabling a first node to receive the first signaling; and sending the first signal. The first signaling is used for determining configuration information of the first signal; the first signaling is used for determining a first information unit, the first information unit comprises a first domain, the first domain in the first information unit indicates a first reference signal resource, and the first reference signal resource is used for determining a spatial filter of the first signal; a first power control parameter set is used for determining the sending power of the first signal, and the relation between the first power control parameter set and the first information unit is related to the transmission type of the first signal. According to the method, uplink and downlink beam management mechanisms are unified, and the power control problem of uplink transmission is solved under the unified beam management mechanism.

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...
