Title
(EN) Signal transmission method and communication device
(ZH) 传输信号的方法和通信装置
Abstract
(EN)
The invention provides a signal transmission method and a communication device, and the method comprises the steps that terminal equipment receives configuration information, wherein the configurationinformation is used for configuring the terminal equipment to send M signals in a first time unit, the terminal equipment is provided with N antenna panels, M is an integer greater than or equal to 1, and N is an integer greater than or equal to 2; and the terminal equipment sends at least one signal in the M signals through at least one antenna panel in the N antenna panels according to the first information. According to the embodiment of the invention, the terminal equipment can select a panel according to the first information and select signals needing to be sent, a scheme for determining signals needing to be sent is provided, and the problem that when a transmission point indicates the terminal equipment to send one signal or send multiple signals at the same time, the terminal equipment cannot select an antenna panel to send the signals is solved.
