Abstract

The invention provides a signal transmitting and detecting device, a system and a method. The device determines a time unit used for transmitting a synchronization signal in each time window,and transmits a synchronization signal on a determined time unit of each time window. The synchronization signal is fixed on a time unit at a fixed position in each time window, so that only the equipment at the receiving end needs to detect the synchronization signal on the time unit fixed in each time window, and the complexity of the synchronization signal design and detection is reduced.

Description

[0001] This application is a divisional application with the application number 201480033936.2 and the title of the invention is signal transmission and detection device, system and method. technical field [0002] The present invention relates to communication technology, in particular to a signal sending and detecting device, system and method. Background technique [0003] In high-frequency scenarios, in order to overcome large transmission loss, some common channels or reference signals, such as Downlink Measurement Reference Signal (DL-MRS for short), Physical Broadcast Channel (PBCH for short), The transmission of Primary Synchronization Signal (PSS for short), Second Synchronization Signal (SSS for short) and so on needs to be transmitted through Beam Forming (BF for short) technology, that is, the antenna array is shaped to form a beam to generate large antenna gain. The user equipment in the network or cell transmits signals in a time-division manner, that is, the ...
