Embodiment Construction

[0047] The technical solution in this application will be described below in conjunction with the drawings.

[0048] In order to solve the problem in the prior art that when the terminal receives multiple trigger information of the same reference signal, the terminal does not know how to process it. The embodiments of this application are based on figure 1 The shown communication system proposes a transmission method, which can send the reference signal of this type according to multiple trigger information of the same type of reference signal received by the terminal.

[0049] Such as figure 1 As shown, the embodiment of the present application provides a communication system 100. The communication system 100 includes at least two network devices and at least one terminal. A terminal connects to a network device through a wireless interface for communication, and can also communicate with another terminal, such as communication in a device to device (D2D) or machine to machine (M...

Abstract

The invention provides a transmission method, a terminal and network equipment. According to the embodiment of the invention, the sending processing of a first reference signal can be carried out under the condition that the terminal receives a plurality of pieces of first trigger information, so that the problem that the sending processing of the reference signal by the terminal is inconsistent after the terminal receives the plurality of pieces of first trigger information in the prior art is solved, and the system performance can be improved. The method comprises: the terminal receives a plurality pieces of downlink control information (DCI), the DCI at least comprising first trigger information in one-to-one correspondence with the DCI, and the first trigger information being used forindicating resources used by the first reference signal to the terminal and / or sending the first reference signal; the terminal determines target first trigger information from the plurality of piecesof first trigger information; and the terminal sends the first reference signal according to the target first trigger information.

Description

Technical field [0001] This application relates to the field of communications, and more specifically, to a transmission method, terminal, and network device. Background technique [0002] Coordinated multipoint transmission (CoMP) is a method to solve the problem of inter-cell interference and improve the throughput of cell-edge terminals. In CoMP, such as non-coherent joint transmission (NCJT) scenarios, each network device can independently send downlink control information (downlink control information, DCI), that is, each network device is independently scheduled, and the terminal can receive at the same time Multiple DCI. Since each DCI contains reference signal trigger information, such as uplink sounding reference signal (sounding reference signal, SRS) trigger information, demodulation reference signal (demodulation reference signal, DMRS) trigger information, etc., the terminal will receive similar information Multiple trigger information for reference signal. As for...
