Description

A kind of method and device of beam Synchronization Technical field
The present invention relates to field of communication technology more particularly to a kind of method and devices of beam Synchronization.
Background technique
The 5th generation (the 5 of futurethGeneration, abbreviation 5G) development of network technology is the common networking of a variety of wireless access technologys (radio access technology, abbreviation RAT).In order to realize the rapid deployment of 5G, the first stage of 5G development may be with long term evolution (Long term evolution, abbreviation LTE) for main RAT, and 5G technology is the mode of lean RAT (thin RAT).Control face data only passes through LTE technology and sends, and user face data is sent by 5G technology, and can carry out combined dispatching with LTE.For opposite LTE technology, 5G technical work frequency range is higher, and has different waveforms, and multi-access mode and time delay based on data transmission etc. require, and signal quality is also different in data transmission procedure.
Network architecture under a kind of more RAT common networking modes of the following 5G is as shown in Figure 1, can have the small station of multiple 5G RAT in the base station range of a LTERAT.Small station can be used for the reliability of improve data transfer, and the communication of small station and terminal (user equipment, abbreviation UE) use 5G technology.
Can have multiple wave beams (beam) in the coverage area of each base station (small station including 5G RAT) in 5G system, UE can just carry out sending and receiving for data after needing to realize beam Synchronization between the base station of access.
The mode of the beam Synchronization of UE and base station is realized in the prior art are as follows: UE carries out beam search whithin a period of time, and the specific search process of wave beam is the process that UE carries out coherent operations to synchronization signal received on each wave beam.In the prior art, base station successively sends synchronization signal by each wave beam of base station in different radio frames, and UE needs to attempt to receive the synchronization signal on each time and carries out coherent operations until and in one of beam Synchronization.If thering are 16 wave beams successively to send in different radio frames under the base station to synchronize Signal (such as: first radio frames sends out the synchronization signal of first wave beam, second radio frames sends out the synchronization signal of second wave beam, transmission of other synchronization signals and so on), and UE is in the 16th wave beam, and base station just sends signal on first wave beam at this time, so UE needs successively to carry out coherent operations with each wave beam respectively, until determining that itself needs synchronous wave beam.
So when number of beams is more, it is time-consuming more that the mode of above-mentioned beam search will lead to search process, and synchronization delayed time is caused to increase.
Summary of the invention
The present invention provides a kind of method and device of beam Synchronization, and method and apparatus provided by the present invention solve the problems, such as that existing beam Synchronization mode is time-consuming more.
In a first aspect, providing a kind of method of beam Synchronization, it is applied to terminal side, comprising:
Terminal UE receives the synchronization signal that the base station including at least one wave beam is sent by each multi-beam beam;Wherein, which includes the distinctive information for distinguishing the wave beam for sending the synchronization signal;
Strongest first synchronization signal of signal is determined from least one synchronization signal received;
It determines corresponding first distinctive information of first synchronization signal, determines that the corresponding wave beam of first distinctive information is the synchronous wave beam of the UE according to preset distinctive information and the corresponding relationship of wave beam.
Method by implementing first aspect description, terminal can use code point, time-division, frequency division receives synchronization signal, then in the wave beam that determine UE using each coding, moment and frequency domain resource and the corresponding relationship of wave beam synchronous, so as to effectively shorten the synchronous duration of UE, the effect for reducing synchronization delayed time is played.
Second aspect provides a kind of method of beam Synchronization, is applied to base station side, comprising:
Base station including at least one wave beam sends synchronization signal by each multi-beam beam;Wherein, which includes the distinctive information for distinguishing the wave beam for sending the synchronization signal;So that receiving the terminal of the synchronization signal wave beam that according to corresponding first distinctive information of the first synchronization signal and preset distinctive information and the corresponding relationship of wave beam to determine UE synchronous;First synchronization signal is to believe in the synchronization signal Number strongest signal.
