Abstract

An embodiment of the present invention provides a signal transmission method and device, the method comprising: determining a transmission time of a first type of reference signal; sending a first type of reference signal according to the transmission time of the first type of reference signal, and / or Or receive a reference signal of the first type; where in an uplink-downlink switching period, the downlink transmission of the communication device is before the sending time of the reference signal of the first type, or the downlink transmission of the communication device cannot exceed the first The sending moment of the reference signal of the first type, or the communication device has no downlink transmission after the sending moment of the first type of reference signal. In the embodiment of the present invention, the communication device serving as the interfering station can receive the interfered reference signal within the uplink time period of the original frame structure, and can determine the number of backed-off symbols.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communications, and in particular to a signal transmission method and device. Background technique [0002] see figure 1 , in time division duplex (Time Division Duplexing, TDD) system networking, in order to avoid uplink and downlink interference between cells, the same uplink and downlink configurations are generally selected. And a guard period (Guard Period, GP) is set between the downlink and uplink transmissions, which is generally N (for example: less than <14) Orthogonal Frequency Division Multiplexing (OFDM) symbols. The selection of the GP length needs to ensure that the downlink transmission of the base station within a certain range (for example ~ tens of kilometers) will not interfere with the uplink reception of the base station. [0003] Usually, considering the loss of electromagnetic wave propagation in space, the base station does not experience the interfe...
