Description
Technical field
The present invention relates to the communication technology, particularly a kind of method of mobile communication and equipment.
Background technology
Transmission duplex mode in the wireless communication technology has two kinds, and a kind of is FDD (Frequency DivisionDuplex, Frequency Division Duplexing (FDD)) mode, and another kind is TDD (Time Division Duplex, a time division duplex) mode.
3G (Third Generation) Moblie (3G) technology is the wireless communication technology of current main-stream, in the 3G standard of three kinds of main flows, and WCDMA (Wide-band CDMA, wideband CDMA; CDMA:Code DivisionMultiple Access, CDMA access system) and CDMA2000 employing FDD mode, uplink and downlink works frequency difference need be configured to right frequency range when networking; And TD-SCDMA (Time DivisionSynchronized Code Division Multiple Access, the time-division synchronous CDMA system) adopts the TDD mode, uplink downlink is operated in same frequency, when networking, do not need to be configured to right frequency range, thereby spectrum arrangement is flexible, can use various dispersions, scrappy idle frequency range.TDD can dynamically adjust uplink and downlink timeslot simultaneously, can adapt to the demand of up-downgoing asymmetric traffic efficiently.
The physical channel structure of TD-SCDMA comprises radio frames, subframe and time slot/sign indicating number, and according to different Resource Allocation Formulas, the configuration structure of subframe or time slot/sign indicating number may be different.Time slot is used for distinguishing the different user signal on time domain and sign indicating number territory, and it has the TDMA characteristic.Fig. 1 is a TD-SCDMA physical channel signal form schematic diagram; Fig. 2 is a TD-SCDMA subframe structure schematic diagram; as shown in the figure; physical channel under the tdd mode is a burst; be made up of data division, training sequence (being the midamble sign indicating number) part and a protection time slot, the duration of a burst is exactly a time slot.The data division of burst is by channel code and the common spread spectrum of scrambler.Channel code is an OVSF (Orthogonal Variable Spreading Factor, an Orthogonal Variable Spreading Factor OVSF) sign indicating number, and spreading factor can get 1,2,4,8 or 16, and the data rate of physical channel depends on the used spreading factor that ovsf code adopted.
The training sequence part of burst is one and longly is the training sequence code of 144chips (being the midamble sign indicating number).
The length of TD-SCDMA frame is 10ms, is divided into two 5ms subframes, and the structure of 2 subframes in every 10ms frame length is identical, as shown in Figure 1.
As shown in Figure 2, among the figure:
Time slot n (n from 0 to 6): n business time-slot, 864 chip durations;
DwPTS (Downlink Pilot Time Slot): descending pilot frequency time slot, 96 chip durations;
UpPTS (Uplink Pilot Time slot): uplink pilot time slot, 160 chip durations;
The main protection interval of GP (Guard Period): TDD, 96 chip durations.
As shown in the figure, the uplink and downlink business time-slot adds up to 7 in each subframe, and the length of each business time-slot is the duration of 864 chips.In 7 business time-slots, time slot 0 is always distributed to down link, and time slot 1 is always distributed to up link.Separate by a transfer point between the time slot of up link and the time slot of down link.Between descending time slot and ascending time slot, special interval is as the transfer point of uplink and downlink.In the subframe of each 5ms, two transfer points (downstream-to-upstream and be up to descending) are arranged.
In above-mentioned frame structure, can be easily by changing uplink and downlink timeslot number so that system works in symmetry and asymmetric mode.Be noted that it is descending to have a time slot (time slot 0) to distribute at least, at least one time slot (time slot 1) must be distributed to up.Fig. 3 TD-SCDMA subframe structure diagrammatic sketch, Fig. 3 provided respectively symmetrical distribution and asymmetric distribution uplink downlink example, wherein DL is descending, UL's is up.By above the subframe structure reception of TD-SCDMA signal and the mode that TDD is adopted in emission as can be seen, and can be by changing the time scale that switching point come the flexible configuration transmitting-receiving, for example network equipment can 1,2,3 be received 4,5,6, or 1,2,3,4,5,6 receive.
Along with developing rapidly of mobile broadband, particularly the requirement of downstream rate is more and more higher to speed for the user, provides higher bandwidth and littler transmission delay to become the problem that needs emphasis to consider for mobile communication system.
In order to reach higher speed, enhancement mode UMTS (Universal Mobile TelecommunicationSystem, universal mobile telecommunications system) technology-HSDPA (High Speed Downlink Packet Access, high speed downlink packet inserts) and the standardization of HSUPA (High Speed Uplink Packet Access, high speed downlink packet access) technology finish substantially.For TD-SCDMA, can realize the speed of descending 2.8Mbps and up 2.2Mbps in theory.
But in TD-SCDMA, realize HSDPA/HSUPA, typical uplink and downlink timeslot is configured to 2:4 and 3:3, remove again and follow DPCH (Dedicated Physical Channel, DPCH) and the shared resource of Common Control Channel, the resource that then above two kinds of configuration residues are used for HSDPA and HSUPA business has only up 1 time slot or 2 time slots, descending 3 time slots or 2 time slots.Like this, the HSDPA/HSUPA about 0.56Mbps/1.68Mbps of true peak speed or the 1.12Mbps/1.12Mbps that can reach.
And the transmission bandwidth that can provide in 1.6MHz for TD-SCDMA is always limited, in order further to improve speed and increase capacity, can adopt the method for multicarrier, also can seek other frequency ranges in addition, the system of development support multiband.But these two kinds of shortcomings that method is had nothing in common with each other, for example multicarrier has limited uplink and downlink and has realized high-speed data service simultaneously because the uplink and downlink timeslot transfer point must be consistent.Multiband can be provided with different time slot transfer points at different frequency range, but UE must support simultaneously that above-mentioned frequency range could realize corresponding business, simultaneously owing to the increase of frequency range, has prolonged the time of UE initial cell search, and user experience is relatively poor.

Embodiment
For higher bandwidth is provided, a kind of method of mobile communication and equipment are provided in the embodiment of the invention, below in conjunction with accompanying drawing the specific embodiment of the present invention is described.
Fig. 4 is a method of mobile communication implementing procedure schematic diagram, as shown in the figure, can comprise the steps: in mobile communication
In the invention process, UE inserts wireless access network equipment on primary band, and initiates to insert at random; Insert at random finish after, in step 402,403, will on primary band and at least one auxilliary frequency range, set up Radio Link and at the Radio Link transmitting data.In the enforcement, auxilliary frequency range can be a plurality of, it is at least one auxilliary frequency range, owing on each auxilliary frequency range, set up Radio Link in implementing, and it is identical at the execution mode of Radio Link transmitting data, therefore when below the enforcement of each step being described, for convenience of description, with one of them auxilliary frequency range is that example describes, that is, be that example describes with a primary band and an auxilliary frequency range, know easily, when having a plurality of auxilliary frequency range, press the execution mode of an auxilliary frequency range among the embodiment and on each auxilliary frequency range, implement to get final product, therefore, will be when describing not to a primary band, a plurality of auxilliary frequency ranges illustrate especially.
1, at first primary band and auxilliary frequency range are described.
The space requirement of frequency division duplex system can be satisfied in the interval of primary band and auxilliary frequency range.
Primary band can adopt in the frequency range that country distributes than low-frequency range, or adopt the comparatively ripe frequency range of system development as primary band; Auxilliary frequency range can adopt fragmentary frequency range.
In the enforcement, if when communication system is TD-SCDMA, primary band can be selected the frequency range of 2010-2025MHz.
For higher bandwidth is provided, not only can work on the some frequencies in some frequency ranges in the enforcement, can also on two frequencies of two frequency ranges, work simultaneously, wherein the former structure of time slot and working method and original TDD system are identical, be called primary band, the latter is the expansion of primary band, has only descending time slot or ascending time slot, is called auxilliary frequency range.
Fig. 5 is the distribution schematic diagram of each frequency in major-minor frequency range and the frequency range, as shown in Figure 5, because the frequency range electromagnetic propagation characteristic that frequency is lower is better relatively, therefore primary band can adopt in the frequency range that country distributes than low-frequency range, also can adopt the comparatively ripe frequency range of system development as primary band in addition, for example TD-SCDMA has begun commercialization in the 2010-2025MHz frequency range, considers and the compatibility of commercial system, also can use the 2010-2025MHz frequency range as primary band.Identical with original TD-SCDMA system, primary band comprises 9 frequencies.
The space requirement of frequency division duplex system should be satisfied in the interval of primary band and auxilliary frequency range, much larger than system bandwidth.
The bandwidth of auxilliary frequency range does not need FDD to choose the up-downgoing symmetrical frequency band like that, and can adopt some fragmentary frequency ranges, therefore improves the utilization rate of frequency spectrum to a great extent.
Because it is far away that major-minor two frequency ranges generally are separated by, therefore general needs two overlap independent receiver for UE.According to the disposal ability of UE, carrying RRC (Radio Resource Control, Radio Resource control) connects or the physical channel of RB (Radio Bearer, radio bearer) can assign to two frequency ranges simultaneously, at this moment needs two cover receivers to work simultaneously; Or just auxilliary frequency range, at this moment only need a cover operation of receiver.
2, the wireless transmission method on primary band and the auxilliary frequency range.

Receive and emission The data TDD mode at primary band, carry out the up-downgoing transfer of data in the mode of time-division;
Have downlink data transmission or transmitting uplink data in auxilliary frequency range, the transmission duplex mode of primary band and auxilliary frequency range adopts the FDD mode.
Wireless access network equipment and UE when the Radio Link transmitting data of primary band and auxilliary frequency range can be:
Auxilliary frequency range and primary band adopt structure of time slot of the same type.
Wireless access network equipment and UE when the Radio Link transmitting data of primary band and auxilliary frequency range can be:
The time slot of auxilliary frequency range is descending time slot or is ascending time slot.
Fig. 6 is the structure of time slot schematic diagram of primary band and auxilliary frequency range, and as shown in the figure, system adopts the TDD mode in the Data Receiving of primary band and emission, and existing ascending time slot also has descending time slot on a frequency, and is identical with general TDD system; Auxilliary frequency range adopts similar structure of time slot with primary band, and different is that all time slots are descending time slot, or is ascending time slot, is descending time slot because the downloading flow of common data service greater than uploading, generally requires more.The transmission duplex mode of major-minor frequency range can adopt the FDD mode.
Fig. 7 is the primary band of TD-SCDMA and the structure of time slot schematic diagram of auxilliary frequency range, as shown in the figure, structure of time slot with TD-SCDMA is an example, this system adopts the TDD mode, existing ascending time slot also has descending time slot on a frequency, in these 7 business time-slots, time slot 0 is always distributed to down link, and time slot 1 is always distributed to up link.Separately can be between the time slot of up link and the time slot of down link easily by changing the number of uplink and downlink timeslot by a transfer point, so that system works the symmetry and asymmetric mode, this frequency range of the original structure of time slot of system of utilizing is called primary band.
Auxilliary frequency range adopts similar structure of time slot to primary band, and different is that all time slots are descending time slot, or is ascending time slot, because the downloading flow of data service generally requires more descending time slot greater than uploading usually.The transmission duplex mode of main and auxiliary frequency range adopts the FDD mode.

For the convenience of describing, the each several part of the above device is divided into various modules with function or the unit is described respectively.Certainly, when enforcement is of the present invention, can in same or a plurality of softwares or hardware, realize the function of each module or unit.
In the invention process process, adopted in the frequency range of national distribution than the ripe frequency range of low-frequency range or system development as primary band.
Also in the Data Receiving and the emission employing TDD mode of primary band, can there be up-downgoing simultaneously in the implementation process; Auxilliary frequency range has only descending (or having only up), and the transmission duplex mode of major-minor frequency range adopts the FDD mode.
Also adopt similar structure of time slot in auxilliary frequency range to primary band in the implementation process, different is that auxilliary all time slots of frequency range are descending (or up) time slot.
Also adopted in the implementation process primary band information can be stored in the usim card, just can read this information after making the user start shooting and begin initial cell search at each frequency of this primary band.
Also adopted other frequency ranges as auxilliary frequency range in the implementation process, only inserted at random behind the UE persistent district, the downlink allocation of RRC connection or RB can have been arrived auxilliary frequency range after the access at primary band.
In summary:
1, the interference between the up-downgoing that causes in the time of can solving the different time-gap transfer point networking of TDD base station in the invention process process as can be seen by above-mentioned enforcement.
Because TD-SCDMA can be by changing the time scale that switching point come the flexible configuration transmitting-receiving, so the ratio of up-downgoing can change between 1: 5 to 3: 3, was particularly suitable for the asymmetric data service of up-downgoing.But bring very big difficulty but up-downgoing is asymmetric to networking, need very big isolation between the sub-district of different time-gap switching point, because the up-downgoing that the switching point difference is brought is disturbed, have significant limitation in the actual operation to avoid, only be fit to part scenes such as indoor covering.
But in the invention process, owing to adopt the mode of F-TDD, owing to introduced at least one auxilliary frequency range, two frequency range additions are up can dispose 1-3 time slot, descendingly can dispose 3-10 time slot.If primary band is fixing with the 3:3 networking, the ratio of two frequency range up-downgoings is 3: 10, can satisfy the needs of symmetrical service and non-symmetrical service simultaneously.
Therefore the F-TDD mode is compared the TDD mode, can not adopt the mode that changes switching point also can reach the asymmetric effect of up-downgoing when networking, takes into account symmetrical service and non-symmetrical service preferably.
2, can use fragmentary frequency range in the invention process process as can be seen by above-mentioned enforcement, improve the frequency spectrum utilization rate.
Because insert at primary band, auxilliary frequency range has only descending, the bandwidth of therefore auxilliary frequency range does not need FDD to choose the up-downgoing symmetrical frequency band like that, frequency range is chosen very flexible, minimum only needs 1.6MHz under the limiting case, therefore can use some very fragmentary frequency ranges, thereby improves the frequency spectrum service efficiency.
3, can accelerate the speed of initial cell search as can be seen in the invention process process by above-mentioned enforcement.
Primary band information can be stored in the usim card, just can read this information and begin initial cell search at each frequency of this primary band after user start.Because after having increased at least one auxilliary frequency range, still only on primary band, carry out initial cell search, need be in auxilliary frequency band search sub-district, so be usually operated at two UE on the frequency range and compare, accelerate the speed of cell initial search greatly, improved user experience.
4, can accelerate the feedback speed of ACK/NACK and CQI, TPC etc. as can be seen in the invention process process by above-mentioned enforcement.
Figure 12 is the timing relationship schematic diagram of each interchannel, as shown in the figure, after having increased auxilliary frequency range, spendable number of time slot greatly increases on two frequency ranges, therefore can dispose the more time slot of going up, for example TD-SCDMA can become 3: 10 in original 1: 5, and this chance that makes ACK/NACK return obtains increasing.In general, UE is from receiving HS-PDSCH (High Speed Physical Downlink SharedChannel, the high-speed downstream Physical Shared Channel) data arrive at HS-SICH (High-Speed SharedInformation Channel, high speed uplink is shared information channel) feeding back ACK/NACK and CQI (Channel Quality Indicator, the channel quality indication), TPC (Transmit Power Control, transmitting power control) processing time of 4 time slots of needs, therefore the HS-SICH for Figure 12 can only return at Subframe n+3 originally, uply just had an opportunity to return on Subframe n+2 after becoming 3 time slots.Therefore obtain littler time delay and can in time feed back the variation of dissemination channel.
In addition, for the data on the auxilliary frequency range, because auxilliary frequency range and primary band are the FDD mode, so the mode of the above-mentioned TDD of feedback ratio of ACK/NACK is more timely.
