Abstract

The present invention provides a signal transmission method, device, communication system, terminal and base station, wherein the method includes: determining the repetition factor or spreading sequence of the channel; determining time domain resources according to the repetition factor or the length of the spreading sequence, and the time domain The resource is a transmission subframe; sending a signal by using the transmission subframe of the channel. The signal transmission method, device, communication system, terminal and base station provided by the present invention can solve the technical problem of poor channel coverage in the prior art signal transmission method.

Description

technical field [0001] The present invention relates to communication technology, in particular to a signal transmission method, device, communication system, terminal and base station. Background technique [0002] Orthogonal Frequency Division Multiple Access (OFDMA) has become the system key multiple access of 3G system and / or 4G system, and is the follow-up evolution of Long Term Evolution (LTE) / Long Term Evolution (LTE-Advanced, referred to as: LTE-A) system adopts a multiple access technology. In the multiple access technology, resources used to transmit signals are time-frequency resources, including two dimensions of time and frequency. From the perspective of time dimension, a wireless frame is 10ms in length and contains 10 subframes, each subframe has a length of 1ms, each subframe contains 2 time slots, and each time slot contains 7 (normal cyclic prefix (Cyclic Prefix, Cyclic Prefix, hereinafter referred to as CP)) or 6 Orthogonal Frequency Division Multiple Ac...
