By specific embodiment, the technical scheme that the present invention is provided is described in detail：
Embodiment 1
One preset time period correspondence once complete signal (including synchronizing signal and broadcast channel at least it
One) transmission process, it is assumed that one has N number of synchronous window, and N number of broadcast window, each synchronous window correspondence is unique
Using different in one broadcast window, and 1 wave beam of each synchronous window correspondence, different synchronous window/broadcast windows
Wave beam send synchronizing signal/broadcast channel.
Transmitting terminal (such as base station) is according to relevant information (where UE number, UE position, base station
The factors such as the channel situation of scene) determine it is continuous in the number p of continuous symbol in each synchronous window, broadcast window
The number k of symbol is numerically one-to-one relation with p, and the rule of correspondence is known to receiving terminal.
Wherein p value by other approach can tell receiving terminal by base station, can also be obtained by the blind solution of receiving terminal
Know.It should be noted that the p value of different base station can be different, p value of the same base in different cycles
Can also be different, p can also be different in the different synchronous windows in same period for same base station.It is each same
The sequence walked in window on p symbol is different, but the sequence on different synchronous windows can be the same
's.All symbols on all symbols and all broadcast windows on all synchronous windows constitute a preset time
Section.
In order to increase flexibility and the scalability of system, 5G high frequency communication systems relevant design will also be used for reference
The sequence of synchronizing signal is located in the middle of bandwidth in the reasonable aspect of LTE system design, such as LTE
On 72 subcarriers, so system can be caused flexibly to support various band width configurations, in carrying for the present invention
In the technical scheme of confession, synchronous window and broadcast window are all that several subcarriers taken in the middle of system bandwidth enter
Row is sent.
In a cycle, whether each synchronous window sends synchronizing signal by transmitting terminal (such as base station) root
Determined according to relevant information, if in one transmission, some synchronous window determines to need to send synchronous letter
Number, then the p symbol that this synchronous window includes is required for sending synchronizing signal, and the broadcast corresponding to it
The k symbol that window includes is required for sending broadcast channel；If in once complete transmitting procedure, certain
Individual synchronous window does not send synchronizing signal, then the p symbol and corresponding broadcast window that synchronous window includes include
K symbol do not send synchronizing signal and broadcast channel.With the sequence bag of synchronizing signal in LTE system
Include that main synchronizing sequence is different with secondary synchronization sequences, the sequence of the synchronizing signal of this programme only has one kind, although
This programme sends the sequence of synchronizing signal on multiple symbols in a cycle because scheme in order to
Increase covering and flexibility, and set corresponding to different beams, substantially the synchronous of this programme is believed
Number sequence be only equivalent to main synchronizing sequence in LTE system.
Synchronous window is example that is fixed, being provided in Fig. 4 and Fig. 5 with the relative position of corresponding broadcast window
In, synchronous window is adjacent with corresponding broadcast window.Therefore by being properly received the sequence of synchronizing signal,
Receiving terminal can just know the position of the corresponding broadcast window of synchronous window, and then can just receive broadcast channel and obtain
Take broadcast message.During broadcast channel is received, receiving terminal can be utilized in corresponding synchronous window
The sequence of synchronizing signal carries out channel estimation, and broadcast message is properly received with auxiliary reception end.Disappear in broadcast
One or several in following information is comprised at least in breath：1) the corresponding frame number of broadcast message is sent；2)
Send the corresponding subframe numbers of broadcast message；3) the corresponding subframe internal symbol index of broadcast message is sent；3)
Send the corresponding frame number of broadcast message；4) cell ID.So as to which combined synchronization signal and broadcast channel are completed
The functions such as the notice of timing, cell ID detection and system message.
Embodiment 2
As shown in fig. 6, with high frequency independence networking, the cycle is sent exemplified by signal.Assuming that signal sends the cycle
Equal to the length of radio frames, altogether including M symbol, the overlay area of each base station is about 120 °.
Assuming that channel condition is relatively preferable within a certain period of time under such a scene, therefore base station uses 4 wider
The whole cell of wave cover.Within a signal transmission cycle, there are 4 synchronous windows, and corresponding 4
Window is broadcasted, synchronous window is adjacent with the position of corresponding broadcast window.Symbol numbers in synchronous window are received
End needs blind solution to know, but the mapping relations between synchronous window symbol numbers and broadcast window symbol numbers are received
End is known.In this embodiment, 2 symbols, broadcast window and synchronous window internal symbol are included in synchronous window
The corresponding relation of number is that the symbol numbers of broadcast window are 2 times of synchronous window, therefore each broadcast window includes 4
Individual symbol.The frequency resource that synchronous window takes with broadcast window is identical.Once complete preset time period
Include 24 symbols (M is more than or equal to 24).
In the present embodiment, synchronizing signal and broadcast channel are all sent on all synchronous windows and broadcast window.
In the present embodiment, the position of the synchronized broadcast window in a cycle is to determine, different cycles
Synchronized broadcast window position is identical, and these information known to receiving terminal.The sequence of synchronizing signal uses auto-correlation
Can preferable sequence, such as ZC (Zadoff-Chu) sequences or pseudo noise with cross correlation
The sequence of distinct symbols is different in (Pseudo-noise Sequence, PN) sequence, and same synchronous window,
The sequence that the different synchronous windows of same cell are used is also different.The sequence of neighbor cell is different, but one
The sequence of different districts has repetition (now then can not distinguishing cell ID) in region.
Because synchronous window position is determined, and the sequence of different synchronous windows is different, so receiving terminal is by connecing
Frame timing can just be completed by receiving the sequence of synchronizing signal.Pass through timing relationship or synchronous window and broadcast window
Position corresponding relation, receiving terminal can just receive the broadcast channel of relevant position, during reception, connect
Receiving end can carry out channel estimation with the reception and then acquisition of Secondary Broadcast Channel using the sequence of synchronizing signal
To broadcast message.Broadcast message includes frame number, cell ID and system message etc..
Embodiment 3
As shown in fig. 7, with high frequency independence networking, the cycle is sent exemplified by signal.Assuming that signal sends the cycle
Equal to the length of radio frames, altogether including M symbol, the overlay area of each base station is about 120 °.
Compared with embodiment 2, it is assumed that channel condition is relatively poor within a certain period of time under such a scene, therefore base
Stand using 6 whole cells of narrower wave cover.Within a signal transmission cycle, there are 6 synchronizations
Window, and corresponding 6 broadcast window, synchronous window is adjacent with the position of corresponding broadcast window.Synchronous window
Interior symbol numbers receiving terminal needs blind solution to know, but synchronous window symbol numbers and broadcast window symbol numbers it
Between mapping relations receiving terminal be known.In this embodiment, 4 symbols, broadcast are included in synchronous window
Window and the corresponding relation of synchronous window internal symbol number are that the symbol numbers of broadcast window are 1 times of synchronous window, because
This each broadcast window includes 4 symbols.The frequency resource that synchronous window takes with broadcast window is identical.One
Secondary complete preset time period includes 48 symbols (M is more than or equal to 48).
Transmitting terminal (such as base station) can determine whether needed on each synchronous window and broadcast window as needed
Synchronizing signal and broadcast channel are sent, but whether each synchronous window and broadcast window corresponding with it send message
It is consistent.In the present embodiment, synchronized broadcast window 5 in the previous cycle with it is same in rear a cycle
Step broadcast window 1 does not send synchronizing signal and broadcast channel, i.e., in the wave beam 5 in previous cycle and latter
Synchronizing signal and broadcast channel are not sent on the wave beam 1 in cycle.But the position of each synchronous window and broadcast window
Keep constant.Corresponding to previous synchronous window and broadcast window 5 and latter synchronous window and broadcast window 2
Other data can be transmitted on running time-frequency resource.
In the present embodiment, the position of synchronous window and broadcast window is to determine in a cycle, different cycles
Synchronous window with broadcast window position it is identical.The sequence of synchronizing signal uses auto-correlation and cross-correlation better performances
Sequence, and in same synchronous window distinct symbols sequence it is different, the different synchronous windows of same cell are used
Sequence it is the same.The sequence of different districts is different (now then can be with distinguishing cell ID) in one region.
Because the sequence of different synchronous windows is the same, so receiving terminal can not be by receiving the sequence of synchronizing signal
Complete frame timing, but be due to that the sequence that each cell is used is different, thus receive synchronizing sequence can be with
Recognize cell ID.By the position corresponding relation of synchronous window and broadcast window, receiving terminal can just be received accordingly
The broadcast channel and then acquisition broadcast message of position, during reception, receiving terminal can utilize synchronous letter
Number sequence carry out channel estimation with the reception of Secondary Broadcast Channel.Broadcast message includes frame number, subframe
Number, subframe internal symbol index and system message etc..
Embodiment 4
As shown in figure 8, with high frequency independence networking, the cycle is sent exemplified by signal.Assuming that signal sends the cycle
Equal to the length of radio frames, altogether including M symbol, the overlay area of each base station is about 120 °.
Compared with embodiment 2, it is assumed that channel condition is relatively poor within a certain period of time under such a scene, therefore base
Stand using 6 whole cells of narrower wave cover.Within a signal transmission cycle, there are 6 synchronizations
Window, and corresponding 6 broadcast window, synchronous window is adjacent with the position of corresponding broadcast window.Synchronous window
Interior symbol numbers receiving terminal needs blind solution to know, but synchronous window symbol numbers and broadcast window symbol numbers it
Between mapping relations receiving terminal be known.In this embodiment, 4 symbols, broadcast are included in synchronous window
Window and the corresponding relation of synchronous window internal symbol number are that the symbol numbers of broadcast window are 1 times of synchronous window, because
This each broadcast window includes 4 symbols.The frequency resource that synchronous window takes with broadcast window is identical.One
Secondary complete preset time period includes 48 symbols (M is more than or equal to 48).
In the present embodiment, all sent in all synchronous windows and corresponding broadcast window and by corresponding wave beam
Synchronizing signal and broadcast channel.
In the present embodiment, the position of synchronous window and broadcast window is uncertain, different weeks in each cycle
The synchronous window and broadcast window position of phase can be differed, within each cycle, transmitting terminal (such as base station)
The position of synchronized broadcast window can be determined as needed, as shown in figure 5, in former and later two cycles, together
The position of step broadcast window is different.The sequence of synchronizing signal can preferable sequence using auto-correlation and cross correlation
Row, and in same synchronous window distinct symbols sequence it is different, the sequence that the different synchronous windows of same cell are used
Row are the same.The sequence of neighbor cell is different, but the sequence of different districts has repetition (this in a region
When then can not distinguishing cell ID).
Due to the sequence of different synchronous windows is the same and a region in the sequence that uses of each cell have repetition,
So receiving terminal can not the sequence of synchronizing signal completes frame timing and cell ID is detected by receiving.Therefore it is logical
The position corresponding relation of synchronous window and broadcast window is crossed, receiving terminal can just receive the broadcast letter of relevant position
Road, during reception, it is wide to aid in that receiving terminal can carry out channel estimation using the sequence of synchronizing signal
Broadcast the reception of channel and then obtain broadcast message.Broadcast message include cell ID, frame number, subframe numbers,
Subframe internal symbol index and system message etc..
