Abstract

The invention discloses a transmitting method and device. The method includes the following steps that: time-domain signals corresponding to frequency-domain signals except primary synchronization frequency-domain signals are acquired; one primary synchronization time-domain signal is determined from at least two pre-stored primary synchronization time-domain signals so as to be subjected to weighting processing; and the time-domain signals and the primary synchronization time-domain signal which has been subjected to the weighting processing are added together, and then, are transmitted. With the transmitting method and device adopted, the problem of the monotonicity of signal transmitting modes in the prior art can be solved, and transmitting modes can be diversified.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a transmitting method and device. Background technique [0002] In wireless communication, synchronization signal detection is required before synchronization is established between the system side and a user equipment (UE), and the synchronization signal must have strong autocorrelation and low cross-correlation characteristics, so as to ensure that the terminal equipment It can access the base station under the condition of low SINR (Signal to Interference plus Noise Ratio). Generally, when designing a synchronization signal, a primary synchronization signal and a secondary synchronization signal are designed. The primary synchronization signal is used for coarse synchronization, and the secondary synchronization signal is used to precisely determine the position of frame synchronization. At present, when the base station transmits signals, the synchronous signal and other ...
