Embodiment Construction

[0070] The terminal accesses a core network (core network, CN) through a radio access network (radio access network, RAN). The technology described in the present invention can be applied to long term evolution (long term evolution, LTE) system, or other wireless communication systems using various wireless access technologies, such as code division multiple access, frequency division multiple access, time division multiple access, regular Cross frequency division multiple access, single carrier frequency division multiple access and other access technology systems. In addition, it can also be applied to subsequent evolution systems that use the LTE system, such as the fifth-generation 5G system.

[0071] For the sake of clarity, only the LTE system is taken as an example for description here. figure 1 It is a system architecture diagram provided by the embodiment of the present invention. refer to figure 1 , in an LTE system, an evolved universal terrestrial radio access n...

Abstract

An embodiment of the present invention provides a signal transmission method, including: a first base station determines a second timing for sending a first symbol to a terminal; the first base station determines a first timing for sending the first symbol to a second base station , the first timing is determined at least by the second timing and a time offset between base stations; the first base station uses the first timing to send the first symbol to the second base station. Through the technical solution provided by the invention, the signals transmitted between the base stations can be completely and correctly received.

Description

technical field [0001] The present invention relates to wireless communication technology, in particular to a signal transmission method, device and system. Background technique [0002] The transceiver entity referred to in the current wireless air interface technology includes a base station and a terminal, and mainly involves air interface transmission between the base station and the terminal. [0003] With the continuous emergence of various new services and new technologies, more and more attention is paid to the transmission between base stations and between terminals. [0004] However, no matter the transmission between base stations or between terminals, there is a problem that the receiver of the transmission cannot correctly receive the signal sent by the sender. Contents of the invention [0005] The present invention provides a signal transmission method, so that the receiver in the transmission between base stations and the transmission between terminals can...
