Embodiment
The problems referred to above to the prior art existence; The embodiment of the invention has proposed to utilize protection to dispose TDD system and corresponding data transmission method at interval; And, can improve the availability of frequency spectrum through the embodiment of the invention according to whether independent the deployment further provided concrete solution.
In the existing spectrum allocation schemes; The middle 50MHz of FDD system uplink and downstream spectrum is used for the TDD system deployment; For guarantee the FDD system and wherein between the TDD system that runs in the frequency spectrum interfere with each other the acceptable scope that drops to; Need to solve more serious descending of interference ratio to up and up to descending cross interference problem, way is that each reserves protection interval G1, G2 in TDD system spectrum both sides usually, its concrete numerical value depends on concrete system configuration and level of hardware.And descending-downlink or uplink-up interference belongs to interference in the same way, and the basic RF index of system meets the demands.Descending one-way data transmission is carried out in the embodiment of the invention utilization protection downlink resource of G1, G2 at interval, and up one-way data transmission is carried out in the utilization protection ascending resource of G1, G2 at interval.Wherein, the downlink resource of protection interval G1, G2 and the descending retention time of TDD system are synchronous, and the ascending time slot of this part resource bans use of; The ascending resource of protection interval G1, G2 and the up retention time of TDD system are synchronous, and the descending time slot of this part resource bans use of.FDD system uplink and TDD system uplink can not need protection at interval; FDD system descending and TDD system descending also can not need protection at interval.
Below in conjunction with accompanying drawing the embodiment of the invention is described in detail.
Embodiment one
Referring to Fig. 4, a kind of TDD system spectrum sketch map that provides for the embodiment of the invention one.As shown in the figure, protecting interval G1 is the protection interval between TDD system and FDD system uplink frequency spectrum, and protection G2 at interval is the protection interval between TDD system and FDD system descending frequency spectrum.The protection at interval U3 part among the G1 will be distributed to subscriber equipment and be used for the transmission of TDD system uplink, and the protection D4 part among the G2 at interval will be distributed to subscriber equipment and be used for the transmission of TDD system descending.
Downlink resource D4 and ascending resource U3 pairing are used, and the carrier wave that constitutes a special TDD system up-downgoing is right.With the difference of general TDD system carrier is that the inconsistent and bandwidth of ascending resource U3 and downlink resource D4 center frequency point can be consistent also inconsistent.Concrete, downlink resource D4 can with the downlink resource TDD DL2 of downlink resource TDD system on frequency spectrum continuously or certain intervals arranged; Downlink resource D4 can with the FDD system spectrum on right side continuously or certain intervals arranged.In like manner, ascending resource U3 can with the ascending resource TDD UL1 of TDD system on frequency spectrum continuously or certain intervals arranged; Ascending resource U3 can with the FDD system spectrum in left side continuously or certain intervals arranged.Downlink resource D4 can equate with the bandwidth of ascending resource D3 or not wait.
When carrying out transfer of data according to frequency spectrum shown in Figure 4; Can ascending resource U3 be distributed to subscriber equipment and send upstream data; Downlink resource D4 is distributed to subscriber equipment send information such as synchronizing channel, broadcast channel; Make downlink resource D4 and ascending resource U3 can independently support a sub-district, subscriber equipment can be resident in this sub-district.The adjacent TDD system carrier (being expressed as carrier wave 2 among the figure) in downlink resource D4 and left side keeps down-going synchronous, and the adjacent TDD system carrier (being expressed as carrier wave 1 among the figure) in ascending resource U3 and right side keeps uplink synchronous.
Can find out through above description; The embodiment of the invention one is through utilizing the protection interval between TDD system and the FDD system; Expanded the frequency spectrum of TDD system, TDD system up-downgoing frequency is not lined up, upstream and downstream bandwidth equates or is unequal; Exist in the middle of the uplink spectrum or do not exist at interval, exist in the middle of the downstream spectrum or do not exist at interval.Compare with the frequency spectrum of existing TDD system, adopt the frequency spectrum of the embodiment of the invention one to dispose, can improve the availability of frequency spectrum of TDD system.
Certainly, only utilize downlink resource D4 to carry out downlink transfer, or only utilize ascending resource U3 to carry out uplink, also can improve the availability of frequency spectrum of TDD system to a certain extent.
Embodiment two
Referring to Fig. 5, a kind of TDD system spectrum sketch map that provides for the embodiment of the invention two.As shown in the figure, protecting interval G1 is the protection interval between TDD system and FDD system uplink frequency spectrum, and protection G2 at interval is the protection interval between TDD system and FDD system descending frequency spectrum.Protection at interval the U3 among the G1 and protection at interval the U4 among the G2 partly be used for the transmission of TDD system uplink, protection at interval the D3 among the G1 and protection at interval the D4 among the G2 partly be used for the transmission of TDD system descending.
In the TDD system after the spread spectrum, upstream and downstream bandwidth unanimity and frequency alignment.Concrete; Downlink resource D3 equates with ascending resource U3 bandwidth and frequency aligns; Downlink resource D3 can with downlink resource TDD DL1 frequency spectrum continuously or certain intervals arranged; Accordingly, ascending resource U3 can and ascending resource TDDUL1 frequency spectrum continuously or certain intervals (equaling the interval bandwidth between downlink resource D3 and the TDD DL1 at a distance from bandwidth therebetween) arranged.In like manner; Downlink resource D4 equates with ascending resource U4 bandwidth and frequency aligns; Downlink resource D4 can with downlink resource TDD DL2 frequency spectrum continuously or certain intervals arranged; Accordingly, ascending resource U4 can and ascending resource TDD UL2 frequency spectrum continuously or certain intervals (equaling the interval bandwidth between downlink resource D4 and the TDD DL2 at a distance from bandwidth therebetween) arranged.
When carrying out transfer of data according to frequency spectrum shown in Figure 5; Be combined into an expansion carrier wave (being expressed as carrier wave 3 among the figure) at protection interval G1 configurating downlink resource D3 and ascending resource U3; Downlink resource D4 and ascending resource U4 are combined into an expansion carrier wave (being expressed as carrier wave 4 among the figure) in the G2 of protection interval, and these 2 carrier waves satisfy with center spectrum disposes the TDD system synchronization.Carrier wave 3,4 can not independently constitute sub-district (being that subscriber equipment can not reside in this carrier wave); For example, not sending the exclusive signal in sub-district in carrier wave 3 or the carrier wave 4, is example to dispose the LTE system; Like CRS (Cell-specific Reference Signal; The sub-district dedicated reference symbols), CSI-RS (Channel State Information-Reference Signal, channel condition information pilot tone), BCH (Broadcast Channel, broadcast channel), PSS (Primary SynchronizationSignal; Master sync signal)/SSS (Secondary Synchronization Signal, secondary synchronizing signal) etc.This carrier wave is polymerized to the sub-district that other can work alone as extended resources with the mode of carrier aggregation (CA), even only receive/send out the up-downgoing data, do not transmit control channel, its up-downgoing resource is used through the carrier dispatching of striding of other polymerization carrier waves.Concrete data dispatch can realize that promptly its dispatch is at other carrier waves through other carrier waves with the mode of striding carrier dispatching, for example main carrier is dispatched, rather than is carried on the D4 resource.
Consider interference problem, when the FDD system spectrum had use, the resource on the rightabout in the protection that is adjacent at interval can not be dispatched to subscriber equipment and used or use with the low-power that is restricted to certain level.To dispose LTE (Long Term Evolution; Long Term Evolution) system is an example, when the ascending resource of FDD system uses, in the TDD system for fear of the up formation of its left side FDD system is disturbed; Downlink resource D3 does not send CRS, CSI-RS, P-SCH (Primary-Synchronization Channel; Primary synchronization channel carries PSS) wait signal to disturb to reduce, whether allowing to send downlink traffic channel with limited power need be definite according to interference level; In like manner, when the downlink resource of FDD system uses, in the TDD system, disturb for fear of its right side FDD system descending is constituted, ascending resource U3 does not send data, and whether allowing to send reverse link traffic channel with limited power need confirm according to interference level.
In addition, different according to the frequency spectrum authorization conditions of operator, U3 can distinguish separately by use or the use together separately of different operators with D4.
Can find out that through above description the embodiment of the invention two is disposed through above frequency spectrum, defines from carrier wave, can keep TDD system characteristics, i.e. up-downgoing carrier bandwidths unanimity and frequency alignment, just certain part resource of carrier wave is not used.
Certainly, only utilize downlink resource D4 and up and down resource U3 carry out transfer of data, or only utilize downlink resource D3 and up and down resource U3 carry out transfer of data, also can improve the availability of frequency spectrum of TDD system to a certain extent.

When carrying out transfer of data according to frequency spectrum shown in Figure 6, protection resource U3, D4 at interval independently do not constitute carrier wave, but constitutes the carrier wave of bigger bandwidth with adjacent spectra, but the bandwidth of this carrier wave should be no more than the carrier bandwidths of a sub-district in the TDD system.With the LTE system is example, being no more than under the situation of 20MHz according to the carrier bandwidths after the aforesaid way expansion, can reuse existing standard and carry out resource allocation and transfer of data.The adjacent TDD system carrier (being expressed as carrier wave 2 among the figure) in downlink resource D4 and left side keeps down-going synchronous, and the adjacent TDD system carrier (being expressed as carrier wave 1 among the figure) in ascending resource U3 and right side keeps uplink synchronous.
Can find out that through above description the embodiment of the invention three is disposed through above frequency spectrum, has expanded up-link carrier bandwidth and descending carrier bandwidth, thereby has improved the availability of frequency spectrum of TDD system.
Certainly, only expanded downstream carrier bandwidths or only expand the up-link carrier bandwidth also can improve the availability of frequency spectrum of TDD system to a certain extent.
In addition, for reducing to protect bandwidth demand, limiting adjacent FDD system deployment bandwidth is a feasible method, and the high bandwidth of FDD system that for example limits both sides is no more than 10MHz.
