Description

A kind of method, apparatus and system of data communication
Technical field
The present invention relates to mobile communications network field, the more particularly to a kind of method, apparatus and system of data communication.
Background technology
With the use of the development of mobile communication technology, especially intelligent terminal, the hair of mobile network has greatly been promoted Exhibition so that the broadband demand of mobile network is growing, and this growth is also continuing.Root it was predicted that future have 500 Hundred million or more machine type communication (Machine Type Communication, MTC) equipment can connect on the net.At present The development of Intelligent hardware is risen, for example Intelligent bracelet, intelligent watch, intelligent electric meter etc. are gradually received and made by everybody With, it is contemplated that the communication (Machine to Machine, M2M) of following this machine type communication or machine to machine will It is more universal, and higher communicating requirement is proposed to the mobile network in future.
In RAN1#84 meeting of 3GPP, reach an agreement：Multiple differences can be configured in a frequency range Parameter set (numerology), different numerology has different subcarrier in frequency domain intervals, time domain cyclic prefix (Cyclic Prefix, CP) and symbol (symbol) length.Different numerology why is defined mainly to consider not Carrying out 5G needs to be adapted to different types of service, and a variety of types of service have different characteristics, such as high-speed mobile industry Business is then adapted to configuration subcarrier spacing bigger, and a large amount of machine type communication (massive Machine Type Communication, mMTC) then it is adapted to subcarrier spacing smaller.
In addition, 5G considers flexibly to eat dishes without rice or wine, flexibly eat dishes without rice or wine that each subband (sub-band, a numerology may be caused The bandwidth occupied) bandwidth flexibility and changeability, can according to business need dynamic adjust its amount of bandwidth.The above characteristic is just given Radio access technology brings challenge.
In existing Long Term Evolution (Long Term Evolvement, LTE) system, when subscriber access system, lead to Cross random access procedure and carry out system access.Random access procedure includes 4 steps, as shown in figure 1, being passed including targeting sequencing The transmission of defeated, accidental access response, message 3 (is exactly Article 3 message in fact, because in the process of Stochastic accessing, these message Content do not fix, sometimes may carry be wireless resource control connection request, may sometimes disappear with some controls Breath even business data packet, therefore referred to as message 3), contention resolution message.LTE Stochastic accessing is disappeared by four at present (except the special handoff procedure) for ceasing to complete.For Stochastic accessing a piece of news, targeting sequencing (preamble) be It is transmitted in the resource specified, the configuration of random access resource is configured by system message, such as in system Configured in block of information (system information block, SIB).When user equipment (user equipment, When UE) there are data to reach but there is no ascending resource, then uplink scheduling resource (UpLink is obtained by random access procedure Grant, UL grant), and upstream time alignment (Timing Alignment, TA) is carried out simultaneously.
The configuration of random access resource is in time division duplex (Time Division Duplex, TDD) and FDD (Frequency Division Duplex, FDD) is slightly different, but its method is substantially similar.I.e. by specifying running time-frequency resource position Put, and the positional information of running time-frequency resource is broadcasted in SIB message.Specifically, in SIB2 configurations, parch- ConfigIndex is used to configure running time-frequency resource position, and prach-FreqOffset is used to configure frequency domain resource position.FDD is current One resource distribution of frequency domain is only supported in LTE, time-domain resource can have various configurations option, as even subframe, odd numbered sub-frames, All subframes etc..And TDD can then configure multiple resources on frequency domain.
Because random access resource is configured by system message, therefore, one is configured, and will be fixed on one It will not change in the section time, if to change resource distribution, it is necessary to change process by system message to carry out, all terminals are all Need to update its configuration.
The shortcomings that prior art, is：Existing LTE random access resources one are configured, may be in the relatively long time It is interior to change, if during this period of time, the UE of access is more, may cause user access collision increase, so as to cause with Machine is successfully accessed rate reduction, influences Consumer's Experience.In addition, when the UE of access is less, random access resource will not be used as it He uses transfer resource, resource may can be caused to use deficiency again.
For following 5G systems, can support to move bandwidth (Mobile Broad Bandwidth, MBB), MTC, height simultaneously Reliable low time delay communication (Ultra-Reliable Low Latency Communication, URLLC), and its Connection Density Can be very high, after some time it is possible to reach 1,000,000UE/km2 Connection Density, and wherein most may all be MTC device, such Equipment is typically higher to horsepower requirements, transmission have it is sudden, requirement that may be within some period to resource is very more, and Then drastically reduce afterwards.In view of energy consumption problem, it is desirable to which transmission success rate is higher, if being transmitted several times certainly will cause energy consumption higher The problem of.Therefore, traditional LTE random access procedures and access-in resource may not meet the requirement of following 5G systems.

In step 330, configure at least one first access-in resource and at least one second access-in resource extremely A few part is used as available access-in resource, by for indicating that the information of available access-in resource passes through downstream message or descending letter Number send to one or more of user equipmenies, specifically include：
In view of the characteristic of different business, BS can change according to business, the available access-in resource of dynamic configuration.Such as Business activity infrequently when, it is available access-in resource only to configure the first access-in resource.Again for example, in business activity When busy, first, second access-in resource of configuration is available access-in resource.
For example in the case of one kind, first, second, third access-in resource of configuration is available access-in resource, can use not With bit identify first, second, third access-in resource, can be can use using 3 bits to identify which access-in resource. Such as first corresponding first access-in resource of bit, corresponding second access-in resource of the second bit, the corresponding 3rd access money of the 3rd bit Source.When bit value is 1, identifies the access-in resource and can use, when bit value is 0, it is unavailable to identify the access-in resource.Example Such as, the 111 mark access-in resources of BS first, second and the 3rd are currently available, and UE can pass through appointing in these three access-in resources Meaning one or more carrys out access base station；The first and second current access-in resources of 110 marks can use, UE can by first and/ Or second access-in resource carry out access base station；100 mark BS are only configured with the first access-in resource and can use, and UE can only pass through the first access Resource carrys out access base station, the like.When UE receives above-mentioned mark 110, you can know can by the first access-in resource and Second access-in resource carrys out access base station.
It is the first access-in resource, second respectively if same BS is configured with three layers of access-in resource in second of implementation Which access-in resource and the 3rd access-in resource, be can use using 3 bits to identify access-in resource.Such as when value is 000 When, mark only has the first access-in resource can use；When value is 001, mark only has the second access-in resource can use；When value is When 010, mark only has the 3rd access-in resource can use；When value is 011, first, second access-in resource of mark can use, successively class Push away.When UE receives above-mentioned mark 001, you can knowing can be by the second access-in resource access base station.
Which kind of in two ways is either used, is all that be can use using binary number to identify which access-in resource.
In a step 330, base station need will further to indicate the information of available access-in resource by downstream message or under Row signal notifies UE.Specifically, there are a variety of implementations, such as, in a kind of possible implementation, downstream signal is cell Public reference signal (Cell-Specific Reference Signal, CRS).It should be understood that present patent application is public using cell Reference signal is merely illustrative altogether, and the title change of cell common reference signal has no effect on this patent implementation and possible infringement. If following 5G uses new title, as long as the function that the signal corresponding to the new title is undertaken be with the prior art The function that cell common reference signal is undertaken is consistent, should also fall into the protection domain of patent of the present invention.
Usually, for terminal, before Stochastic accessing, it is necessary to complete reference signal (Reference Signal, RS read work).It should be understood that in LTE, cell reference signals sequenceGenerating mode it is as follows：
Wherein nsThe time slot (slot) number in radio frames is represented, l is which OFDM symbol in current slot, c (i) It is a pseudo-random sequence, pseudo-random sequence cinitGeneration initialized by below equation：
Wherein：
In order to which available access-in resource is notified into UE, a feasible implementation method is in the initialization of pseudo-random sequence Increase a content nNrandom_res, i.e., shown in equation below：
Wherein Nrandom_resIt is the binary representation of available access-in resource, n is some positive integer (for example n takes 10), tool Body can be defined by standard.Therefore, terminal can obtain the parameter value by detecting reference signal sequence.
It will be understood by those skilled in the art that it is originally generated formula, n from LTE CRSsMaximum occurrences are 19, l maximum occurrences For 7,Maximum occurrences are 503, and the initialization generation formula of pseudo-random sequence can essentially be expressed as a multinomial： cinit=D10+D+1
Wherein the coefficient maximum of Section 1 is 7 (19+1)+7+1=148, and being expressed as binary system is：10010100, the Binomial is 503, is expressed as binary system and is：111110111, it is seen then that the value entirely initialized has form as shown in table 1：
Table 1
14 bits 0 8 bits 9 bits 1 bit
In order to allow newly-increased field nNrandom_resIt can be emerged from initialization, there is two kinds of implementation methods, when by N is defined as 218, that is, initializing multinomial is：cinit=D18+D10+ D+1, then it initializes each field format and is：
Table 2
11 bits 0 3 bit access-in resources 8 bits 9 bit Cell ID 1 bit CP
Now initialization formula is：
Wherein, " the 3 bit access-in resource " in table 2 is just used to identify the first access-in resource and the second access-in resource, specifically The above-mentioned two ways that access-in resource is identified with binary system is may be referred to, any one.Such as using first way When, 111 the first access-in resources of expression are available, the second access-in resource is available, the 3rd access-in resource can use；101 represent the first access Resource is available, the second access-in resource is unavailable, the 3rd access-in resource can use.During using the second way, 001 represents that only first connects Enter resource can use；010 expression only the second access-in resource can use；011 expression only the 3rd access-in resource can use；100 represent that first connects Enter resource and the second access-in resource can use, the like, repeat no more.
Or above-mentioned initialization multinomial is changed into：cinit=D13+D4+D3+ 1, wherein it is assumed that mark the first access-in resource and The bit of second access-in resource is placed on last field, is 3 bits, as shown in table 3.It should be understood that the present embodiment only provides Example, other any similar approach are considered as identical with this programme.
Table 3
11 bits 0 8 bits 9 bit Cell ID 1 bit CP 3 bit access-in resources
Wherein, " the 3 bit access-in resource " in table 3 is just used to identify the first access-in resource and the second access-in resource, similarly Ground, the above-mentioned two ways that access-in resource is identified with binary system is specifically may be referred to, any one.Such as using During a kind of mode, 111 the first access-in resources of expression are available, the second access-in resource is available, the 3rd access-in resource can use；101 represent First access-in resource is available, the second access-in resource is unavailable, the 3rd access-in resource can use.During using the second way, 001 represents Only the first access-in resource can use；010 expression only the second access-in resource can use；011 expression only the 3rd access-in resource can use；100 tables Show that the first access-in resource and the second access-in resource can use, the like, repeat no more.
It should be understood that either table 2 or table 3, difference are only intended to identify the bit of access-in resource in initialization Position is different.
It should also be understood that 3 bits are by way of example only, in actual implementation process, those skilled in the art can be according to available The number of access-in resource selects suitable bit.For example when the access-in resource of configuration there are 4 grades, 4 bits can be used Position identifies；When the access-in resource of configuration only has 2 grades, can be identified using 2 bits.
Above-described embodiment is that the information for indicating available access-in resource is notified into one or more UE, Ke Yijie by CRS System signaling is saved, improves resource utilization.In another implementation, base station be able to will be indicated available by synchronizing signal The information notice UE of access-in resource.Specifically：
Because master sync signal mainly represents physics ID in cell ID groups, therefore main consideration is taken in auxiliary synchronous signals With the parameter, sequence generating mode is as follows：
Wherein c0And c (n)1(n) it is two scrambler sequences, dependent on master sync signal, by two different cyclic shifts M-sequence generates：
Wherein 0≤n≤30,It is the physics ID in the ID groups of physical-layer cell.It is contemplated that in auxiliary synchronous signals In, the nN of available access-in resource will be identifiedrach_resIt is put into wherein, specifically, scrambler sequence is changed in the following manner Make：
Wherein n is some integer, and the nN that can will identify available access-in resource is transformed more thanrach_resIt is embedded into In scrambler, send to UE sides.Wherein, Nrach_resFor the binary representation of available access-in resource.When UE side joints receive above-mentioned disturb After code, above-mentioned scrambler can be decoded by the existing decoding technique of prior art, obtained for identifying available access-in resource The binary number of information, and then by the available access-in resource, access the base station.
Above-described embodiment is by for indicating that it is one or more that the information of available access-in resource notifies by synchronizing signal UE, in another embodiment, base station can pass through Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) signaling is by for indicating that the information of available access-in resource notifies one or more UE.It should be understood that this is specially Profit application is merely illustrative using Physical Downlink Control Channel, and the title change of Physical Downlink Control Channel has no effect on this patent reality Apply and possible infringement.If following 5G uses new title, as long as the work(that the signal corresponding to the new title is undertaken It can be consistent with the function that Physical Downlink Control Channel in the prior art is undertaken, should also fall into the protection domain of patent of the present invention In.
Because System information block SIB can be transmitted by PDCCH in LTE, and in PDCCH common search section In indicated.The information of available access-in resource when SIB is transmitted, can be so indicated by the implicit carrying of PDCCH signalings, Without requiring that UE carries out the reading of system message.Specifically, PDCCH scrambler is carried out according to equation below：
Wherein c (i) is scrambler sequence, and scrambler sequence maker is carried out by below equation Initialization：
Transformed, can obtained by the initialization formula to scrambler sequence：
Wherein n is some integer, wherein Nrandom_resFor binary number, use In the available access-in resource of mark.
It is similar with CRS method,For 3 bits, so, n can be using value as 212.Likewise, can also be by initially Change multinomial to be changed to：
Wherein it is assumed that random access resource instruction is referred to 3 bits Show.Identified using 3 bits by the way of available access-in resource as with CRS is used, repeated no more here.
Terminal can obtain the information of available access-in resource, so as to obtain before being initially accessed by obtaining PDCCH Random access resource is obtained, and realizes random access procedure.
In addition, in alternatively possible implementation, available access-in resource instruction can also be carried out using MIB. Assuming that using 2 bits, 4 kinds of possibility are identified, can now define 4 kinds of different resource classes.Such as first access-in resource be compared with Few resource, the second access-in resource are second of access-in resource configurations, and more than the distribution of the first access-in resource, the 3rd accesses Resource is more some more than the second access-in resource, what the resource of every kind of rank can be configured with separate configurations or increment, when When being increment configuration, it is that the first access-in resource adds the second access-in resource, the 3rd access-in resource that the second access-in resource, which represents, It is (to contain the first access-in resource) on the basis of the second access-in resource to add the 3rd access-in resource, as shown in Figure 5.
It should be understood that the process that the available access-in resource of mark is carried in MIB is substantially similar with SIB2 message, this hair refer to To how to identify the introduction of the first access-in resource, the second access-in resource in SIB in bright embodiment, repeat no more here.When MIB refers to When showing the access-in resource of some rank, currently used resource distribution is represented, terminal currently connects at random by reading MIB to obtain Enter the configuration of resource.It should be understood that present patent application is merely illustrative using Master Information Block, the title change of Master Information Block has no effect on This patent implements and possible infringement.If following 5G uses new title, as long as the signal institute corresponding to the new title The function that the function of undertaking is with Master Information Block in the prior art is undertaken is consistent, should also fall into the protection domain of patent of the present invention In.
With respect to previous embodiment, this method needs to read mib information, and takes MIB expenses, is that the resource shown is opened Pin, but the method indicated as resource, the purpose of dynamic definition random access resource can also be reached.
It should be understood that the embodiment of the present invention instruction can also will be used for by other message or customized new message can Sent with the information of access-in resource to one or more users, simply compared with above-mentioned use system message, signaling consumption is big, is Resource utilization of uniting is relatively low.
