Embodiment
Express clearly clear for making the object, technical solutions and advantages of the present invention, below in conjunction with drawings and the specific embodiments, the present invention is further described in more detail.
In embodiments of the present invention, different according to subband function, be synchronous subband by multiple sub-band division and asynchronously carry i.e. common sub-band.Synchronous subband mainly completes the transmission of synchronization and broadcast message; Common sub-band is mainly used in the transmission of up-downgoing business.
Are physical layer frame structure schematic diagrames of the present invention see accompanying drawing 3, wireless frame length is 25ms, and every frame comprises 5 subframes.0th subframe 0 is configured to descending, and the second subframe is up to the 4th sub-frame configuration.Each subframe comprises 9 OFDM (OFDM) symbols.First subframe is special subframe, comprises 3 territories, i.e. DwPTS, GP and UpPTS.DwPTS is fixed as descending territory, takies 4 OFDM symbol; UpPTS is fixed as up territory, takies 4 OFDM symbol; GP is empty, takies 1 OFDM symbol.
In the present invention, the effect see Fig. 4 subframe is weakened, and only has the concept of up-downgoing.In Fig. 4, black part is the GP of the first subframe.For the 0th subframe and the DwPTS part of the first subframe and the left side of black box, clearly do not distinguish, downlink resource entirety can be regarded as use purposes; The UpPTS of the first subframe, and as ascending resource on the right side of the second subframe to the 4th subframe and black box, United Dispatching.
In discrete multi-sub-band system, be two classes by multiple sub-band division, a class is synchronous subband, and another kind of is asynchronous subband and common sub-band.Synchronous subband major function has been synchronization and has sent broadcast message, comprises descending synchronous signal channel, broadcast channel and Random Access Channel.Common sub-band is mainly used in the transmission of up-downgoing business.
Lower mask body is with in discrete multi-sub-band system, and being made up of the subband of 40 discrete 25kHz be power network frequency spectrum is that example describes the present invention in detail.
In power network frequency spectrum, each community is by three bunches.Network side arranges synchronous subband at least one bunch, that is network side can arrange synchronous subband in any one bunch in three bunches, also in any two bunches in three bunches, synchronous subband can be set, synchronous subband can also be all set in three bunches.User can search for three bunches respectively, when there being at least two bunches to arrange synchronous subband, then can select signal best bunch to carry out resident; When only there being one bunch to arrange synchronous subband, then reside in this bunch.
Synchronous subband is arranged in each bunch and sends.Best, synchronous subband is arranged in the middle transmission of each bunch, can reduce the amplitude that UE accesses time frequency point leap like this, thus reduction frequency adjusts the frequency deviation brought.See accompanying drawing 5, the default location of first bunch and the 3rd bunch broadcast is the 8th subband (each 7 subbands in left and right), and the broadcast location of second bunch is positioned at the 5th subband (5 4, one side subbands).
(1) synchronous subband
Synchronous subband major function has been synchronization and has sent broadcast message, comprises descending synchronous signal channel, broadcast channel and Random Access Channel.
As shown in Figure 6, in synchronous subband, synchronizing signal (PSS/SSS) i.e. vertical line part and broadcast channel (PBCH) i.e. horizontal line part hocket transmission in units of radio frames on downlink resource.The 0th subframe in downlink resource and synchronous subband radio frames and the DwPTS of the first subframe.
Specifically, synchronizing signal sends to UE in the 0th subframe of synchronous subband first radio frames and the DwPTS of the first subframe, and the frame number of this synchronous subband first radio frames equals 0 to 2 deliverys; Broadcast channel sends to UE in the 0th subframe of synchronous subband second radio frames and the DwPTS of the first subframe, and this synchronous subband second radio frames frame number equals 1 to 2 deliverys.
Certainly, synchronizing signal can also send to UE in the DwPTS of the 0th subframe of synchronous subband first radio frames and the first subframe, and the frame number of this synchronous subband first radio frames equals 1 to 2 deliverys; Accordingly, broadcast channel sends to UE in the 0th subframe of synchronous subband second radio frames and the DwPTS of the first subframe, and this synchronous subband second radio frames frame number equals 0 to 2 deliverys.
Ascending resource (comprising the first subframe UpPts, the second subframe, the 3rd subframe and the 4th subframe) allows user to carry out Stochastic accessing.
Such as, see accompanying drawing 7 be the distribution schematic diagram of random access resource of 8 homogeneous frequency adjacent areas.Vertical line represents synchronizing signal, and horizontal line represents broadcast channel, and black bars represents the random access resource shared by different districts.
The ascending resource of each synchronous subband radio frames is divided into 4 parts according to the time, and continuous two radio frames totally 8 pieces of time resources, one piece of resource that each community accounts for wherein carries out Stochastic accessing.Community uses which the Duan You community ID in 8 time periods in two continuous frames to determine, i.e. the time location of rear three decision random access resources of community physical I D.
(2) common sub-band
Common sub-band is mainly used in the transmission of up-downgoing business, and the frame structure of common sub-band as shown in Figure 8.
In common sub-band, each frequency band sends a synchronizing signal.What the frequency spectrum for power network was discrete is distributed in 230M frequency range, whole frequency band can be divided into 40 discontinuous subbands, then 40 radio frames send a synchronizing signal, for ensureing that UE carries out normal carrier synchronization and time synchronized in this common sub-band, the common sub-band radio frames sending synchronizing signal is called synchronization frame.The cycle of synchronization frame is that radio frames length is determined corresponding to discontinuous subband.Concrete deterministic process is prior art.For the power network frequency spectrum that the subband by 40 discrete 25kHz forms, the cycle of its synchronization frame is 1s, and every 40 radio frames send a synchronization frame.
In other 39 radio frames (i.e. Non-alignment Frame), mainly carry out the transmission of up-downgoing data.Ascending resource (SR) request common sub-band Non-alignment Frame first subframe UpPts position send.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
