Description

Up-link access method and device, emitter, receiver, terminal

Technical field

The present invention relates to the communications field, in particular to a kind of up-link access method and device, hair Penetrate machine, receiver, terminal.

Background technology

Uplink multi-users access can be by different multiple access techniques such as：Time division multiple acess (Time Division Multiple Access, referred to as TDMA), frequency division multiple access (Frequency Division Multiple Access, FDMA), CDMA (Code Division Multiple Access, letter Referred to as CDMA) and space division multiple access (Space Division Multiple Access, referred to as SDMA). In access procedure using CDMA access, first, each access terminal is first with certain length Sequence spreading (e.g., length is L sequence spreading, refers to that this sequence spreading is made up of L symbol, It could also say that and be made up of L element, L symbol or L element herein can be L Numerical chracter) Amplitude is mutually modulated after data symbol be extended.Expansion process refer to it is each The data symbol of modulation is multiplied with each symbol of sequence spreading, ultimately forms and is grown with sequence spreading used The process of identical symbol sebolic addressing is spent, Fig. 1 is data symbol Extended Principle Diagram in correlation technique, is such as schemed Shown in 1, data symbol S_k, the sequence spreading C={ c of a N length₁, c₂... ... c_N, it is so-called Extension process be exactly by S_kWith each element multiplication in sequence spreading C, after finally giving extension Sequence { S_kc₁, S_kc₂... ... S_kc_N}.Each brewed data symbol in expansion process (such as Using two-phase PSK (Binary Phase Shift Keying, referred to as BPSK)/quadrature amplitude modulation Constellation point symbol after (Quadrature Amplitude Modulation, referred to as QAM) modulation) Be multiplied with each symbol of sequence spreading, final each brewed data symbol can be expanded into Sequence spreading length identical symbol sebolic addressing used, if using the sequence spreading that length is L each Modulation symbol can be extended to L symbol, it may also be said to which each brewed data symbol is carried on On the sequence spreading that one length is L.Then, symbol sebolic addressing can after the extension of all access terminals To be sent on identical running time-frequency resource.Finally, what base station received is the extension letter of all access terminals Number conjunction signal being superimposed, and by multiuser receiver technology from close isolated in signal it is each The useful information of terminal.

Traditionally, the communication technology accessed using CDMA is often classified as the classification of spread spectrum communication, this It is because the modulation symbol of terminal can be extended to L times of symbol, if L times of symbol after extending Transmission time requirement is equal to modulation symbol before extension, then required bandwidth will necessarily extend L times. This is also why sequence spreading is frequently referred to frequency expansion sequence.

In CDMA access technology, the expansion process of emitting side be it is fairly simple, only need to be each Modulation symbol, such as the symbol after each BPSK/QAM modulation, the extension sequence with a length for L Each symbol multiplication of row can be obtained by L symbol after extension, and the symbol after then extending can To be launched by single carrier or multi-transceiver technology.Multicarrier code division multiplexing technology is due to that can rely on Multi-transceiver technology is come to anti-multipath, so sequence spreading can need to only consider that being beneficial to multi-user information separates Cross correlation, this is also single carrier code division multiplexing with two kinds of technologies of multicarrier code division multiplexing to sequence The maximum difference of selection.

Good sequence spreading is the basis of performance, and the separation of final multi-user information is complete in base station side Into, base station can obtain corresponding performance using different multi-user reception technologies.Obtain optimal Multi-user data separating property, base station need the multiuser receiver using high-performance but high complexity Technology, such as serial interference elimination receiver technology.

Binary pseudorandom sequence of real numbers can also be referred to as binary pseudo-random sequence, each symbol in sequence Number value is typically expressed as 0 or 1, can also be further represented as bipolar sequence, i.e., 0 is expressed as + 1,1 is expressed as -1, or, 0, which is expressed as -1,1, is expressed as+1.

The length of sequence spreading is also a critical quantity of CDMA.Sequence spreading is longer, respectively Low cross correlation measure used by terminal between sequence spreading is more easily guaranteed that, also, is more easily found More there is the sequence of low cross-correlation, access terminal while so as to support more.If connect simultaneously The terminal quantity N entered is more than the length L, i.e. N of sequence spreading>L, the then it may be said that multiple access System is in overload.Namely the user load rate of code-division multiplexing system can be defined as N/L, If N/L>1 is properly termed as system and is in overload, and Overflow RateHT is also equal to N/L.It is worth one It is mentioned that, it is that CDMA access technology cuts a conspicuous figure in future wireless system that can realize system overload One of determinant attribute.

In order to provide flexible system design, support more users while access, generally access terminal The sequence spreading of use is not mutually orthogonal, up using anon-normal for multiuser information theory angle The multi-access mode of friendship is can to obtain the power system capacity bigger than orthogonal multi-access mode or edge throughput 's.Because the sequence spreading of each terminal is not mutually orthogonal, the generally solution of each user Tonality be able to can be deteriorated with the increase of accessing user's quantity simultaneously.When the system is overloaded, multi-user it Between interference can become more serious.The CDMA of main flow is simple in order to realize at present, mostly It is as sequence spreading based on binary pseudorandom sequence of real numbers.But due to binary pseudorandom real number sequence Row, especially the low cross correlation measure between the shorter binary pseudorandom sequence of real numbers of length is not easy to protect Card, this can cause serious multiuser interference, will necessarily influence the performance of multiple access.

Further, 5G magnanimity connection scene or magnanimity machine communication (Massive machine-type Communication, referred to as MMC) it is that 5G Internet of Things (Internet of Thing, is referred to as IoT) a major class of business.The ultimate challenge of this scene is the number of terminals for supporting magnanimity, certainly will It is required that：The cost of each machine terminal will be far below in general mobile phone terminal；Also foot is obtained in terms of power consumption It is enough low, to ensure the service life of battery；Should also there are stronger robustness, coverage rate in terms of covering The by-places such as basement can be reached.

And conventional orthogonal multiple access has following deficiency：Strict access process is needed, terminal is complicated, cost is high, Power consumption is big；And signaling consumption is too big for parcel, the availability of frequency spectrum is low；Resource quadrature divide, Hard capacity, system flexibility and autgmentability are low.

At present, the research for machine communication access technology is concentrated mainly on following two directions：It is a kind of It is that access technology is once transmitted based on ALOHA agreements (wireless communication protocol most basic earliest) etc. Research, another kind be exactly by improving Long Term Evolution (Long-Term Evolution, referred to as LTE) Contention access technology adapts to the scheme of machine communication special point.

Due to machine communication density of equipment much larger than traditional people and people (Human-to-Human, Referred to as H2H) between the density of equipment that communicates, this can cause will have setting for magnanimity identical at the time of It is standby to be triggered, and (Random Access Channel, be referred to as by RACH RACH access request) is initiated to base station, so this will inevitably cause information collision problem, A series of problems, such as bringing access delay, congestion information in turn, therefore LTE radio access technology is simultaneously Be not suitable for machine communication access technology.Equally, based on the improved access technology schemes of LTE, although can To ensure the reliability of machine communication access technology, but the program needs substantial amounts of signaling consumption, this It can not just meet machine communication to flexibility, low-power consumption, low cost, the demand of less signaling consumption.

Once transmission access technology based on ALOHA its can substantially be divided into two kinds：Its a kind of design is thought Think it is fairly simple, as long as that is, user has data to send, although just they send, certainly, thus Conflict can be produced so as to cause the destruction of frame；Another design philosophy is the number come unification user with clock According to transmission, that is, discrete timeslice is divided time into, user must wait until next timeslice just every time It can start to send data, so as to avoid the randomness that user sends data, reduce data and produce punching Prominent possibility.In second once transmits access technology, the delivery times of data not only will be by The influence of user, but also to be limited by timeslice, i.e., data will be opened when next timeslice It can just be sent during the beginning.

Although once transmission access technology can save substantial amounts of signaling consumption, its reliability but without Method preferably ensured, and magnanimity access during for machine communication, once transmits access technology It is inevitable that more serious collision problem occurs again.

For in correlation technique, access technology is transmitted caused by as the magnanimity of machine communication accesses The problem of Serious conflicts and poor reliability of appearance, not yet propose effective solution.
