Description
Technical field
The present invention relates to wireless communication field, relate in particular to comprehensive use in pairs and base station, portable terminal and the method for non-paired frequency spectrum.
Background technology
Duplex mode is one of feature of distinguishing legacy wireless communication system, also is the essential characteristic that the needs in the system are considered.The duplex mode that many performance and systems adopted of communication system is closely related, and for example: 1) system is to the flexibility of frequency spectrum use; 2) terminal and base station complexity; 3) the use ability of channel information; 4) networking capability; 5) interworking between network ability; 6) to the tenability of moving velocity of terminal.
The duplex mode that the existing communication system is adopted mainly contains three kinds: 1) pure TDD (time division duplex) mode, as the PHS system; 2) pure FDD (Frequency Division Duplexing (FDD)) mode is as the WCDMA system; 3) half-duplex FDD mode is as gsm system.
The major advantage of pure TDD mode is: 1) need not paired frequency spectrum, be convenient to frequency planning; 2) the Receiver And Transmitter channels designs is simple; 3) be convenient to utilize property of channel reciprocity may, make the simplicity of design of smart antenna.The major defect of pure TDD mode is: when 1) overlay area was excessive, the frequency spectrum service efficiency was lower than the FDD mode; 2) support the high-speed mobile aspect not as the FDD mode.
The major advantage of pure FDD mode is: 1) be fit to support high-speed mobile; 2) be fit to big overlay area.The major defect of pure FDD mode is: 1) need paired frequency spectrum, bring the difficulty in the frequency spectrum planning; 2) use of property of channel reciprocity may has difficulties, and makes the design difficulty of smart antenna strengthen; 3) the up-downgoing frequency spectrum uses underaction when supporting non-symmetrical service.
Half-duplex FDD and pure FDD compare, and its advantage is: 1) terminal transmitting-receiving time-sharing work causes terminal passageway simple in structure, and cost is lower; 2) time-multiplexed introducing causes measuring, the realization of function such as switching is easy.
At present, in the research in this field, various duplex modes have been carried out comprehensive assessment, and " arrangement of duplex mode in the following broadband wireless interface (Duplex arrangements for future broadband radio interfaces.IST-2003-507581WINNER D2.5v1.0) " carried out comprehensive assessment to 7 kinds of possible duplex modes as the report in the IST of European Union (informationized society technology) project: 1) pure FDD; 2) pure TDD; 3) half-duplex FDD (GSM); 4) introduce TDD in the FDD uplink spectrum; 5) introduce TDD in the FDD downstream spectrum; 6) FDD of up-downgoing switching; 7) paired TDD.In addition, this report is also discussed CDD.The purpose of these researchs is to seek new duplex mode, perhaps seeks the mode that existing TDD, FDD duplex mode are effectively made up, and reaches the advantage of effectively utilizing TDD and FDD, avoids the purpose of the shortcoming of TDD and FDD as far as possible.
Though several mixing duplex (or cooperative dual duplex) modes of enumerating among the IST WINNER project research report IST-2003-507581 WINNER D2.5 v1.0 have all been improved the deficiency of pure TDD and pure FDD to a certain extent, but, the analysis that the situation that these mixing duplex modes all are based on a pair of FDD frequency spectrum or two TDD frequency spectrums is carried out, there is not to analyze the situation that FDD frequency spectrum (or frequency spectrum) in pairs and TDD frequency spectrum (or non-paired frequency spectrum) are comprehensively used, the a pair of FDD frequency spectrum that particularly has very strong practicality adds the situation of one section TDD frequency spectrum, and IST WINNER project research report IST-2003-507581 WINNER D2.5v1.0 does not analyze.
In the prior art, discussion for flexible use TDD, FDD duplex mode, mainly concentrate on following several respects, from improving the frequency spectrum service efficiency, strengthening professional providing capability, reducing by three aspects of integrated cost of base station and terminal takes all factors into consideration, the various schemes of prior art also have corresponding separately shortcoming, provide several prior art schemes below:
1) introduce the TDD mode in the downstream spectrum of FDD, the frequency spectrum that provides uses the FDD/TDD resource regulating method in division, terminal structure, the FDD downstream spectrum.The characteristics of its terminal structure are two transmission channels and a receive path; The characteristics of the FDD/TDD resource regulating method in its FDD downstream spectrum are the time slot of the nearest terminal from the base station is arranged in the both sides of up-downgoing translation and protection time slot; the terminal of arranging to both sides from the protection time slot is more and more far away from the base station; when terminal after the distance of base station is greater than certain value, just allow this terminal works in the FDD mode.
Its shortcoming mainly is: a) only consider a pair of FDD frequency spectrum on base station and terminal structure, do not have to consider more comprehensive frequency spectrum operating position, add the situation of one section TDD frequency spectrum as the FDD frequency spectrum; B) transmission channel of terminal has two, and receive path has only one, and this is unfavorable for terminal support high-speed downloads business and radio environment measurements; In addition, from scheduling of resource, being arranged into position near the time slot transfer point, far away being arranged near the terminal of base station from time slot transfer point position far away from the base station, farther terminal is arranged in fdd mode, and its shortcoming of such processing is the resource optimization that is unfavorable for high speed mobile terminal.
2) under the situation that the TDD system is covered by the FDD system, use remainder in the uplink spectrum of FDD as the data feedback channel of terminal FDD working method, use the down going channel of TDD frequency spectrum as terminal FDD working method, thereby, the FDD duplex mode of formation one " virtual ".This kind scheme is used the main benefit that the remainder in the uplink spectrum of FDD obtains and is: a) made full use of the remainder in the uplink spectrum of FDD; B) reduced of the interference of TDD terminal to the FDD base station.Wherein, the TDD base station is shaped by downlink wave beam and has alleviated interference to the FDD base station, and the TDD base station is shaped by uplink beam and has alleviated the interference of FDD terminal to the TDD base station.
This shortcoming of using the scheme of the up residual spectrum of FDD is: from the angle of comprehensive use TDD, FDD frequency spectrum TDD and FDD system are not carried out comprehensive Design, just provided and how to have allowed a TDD system that lays separately go to use the method that remainder in another FDD uplink spectrum of laying separately assigns to constitute virtual FDD link, there is TDD system and the FDD system difficulty on coordinating in this scheme in realization, and, can only be to use around the TDD base station in each FDD base station that part of frequency spectrum of quantity minimum in the residual spectrum; Its shortcoming that reduces the method for the interference between TDD terminal and base station and FDD terminal and the base station is: need the coordination complicated between TDD system and the FDD system and the careful network planning, in fact, TDD and FDD system only are only more serious near 1920MHz, and this interference is can be by the comprehensive Design of TDD and FDD system and effectively collaborative the inhibition.
3) filter of traditional transceiver is moved on to before the channel switch, by radio-frequency (RF) switch combination flexibly, the realization system works on different frequency range with different duplex modes (TDD or FDD).
This scheme just is described filter in the transceiver that can support TDD, FDD mixing duplex and the structural relation between the switch, though its structure can be supported TDD and FDD duplex neatly, but and target of the present invention and inconsistent, as, this structure can't be used a pair of FDD frequency spectrum and a TDD frequency spectrum simultaneously.
In a word, prior art can't be accomplished: simultaneously comprehensively use in pairs and non-paired frequency spectrum, improve the frequency spectrum service efficiency, strengthen professional providing capability, reduce the integrated cost of base station and terminal.
