Description

A kind of data transmission method and equipment
Technical field
The present invention relates to wireless communication field, particularly relate to a kind of data transmission method and equipment.
Background technology
M2M(Machine-to-machine, machinery compartment) communicate as a kind of novel communication theory, its objective is and the communication technology of number of different types is organically combined, as: machine-to-machine communication, apparatus control communication, man-machine interaction communication, mobile interchange communication, thus the development promoting social production and life style.
Current mobile communications network for interpersonal communication scheme, as the determination etc. of network capacity.If wish to utilize mobile communications network to support that little bandwidth system communication just needs to be optimized according to the mechanism of feature to mobile communication system of little bandwidth system communication, when not being subject to traditional person to person communication or by less impact, little bandwidth system communication can be realized better.
The current MTC(MachineTypeCommunications recognized, machine-type communication) some characteristics that may exist that communicate have:
MTC terminal has Hypomobility;
The time that MTC terminal and network side carry out transfer of data is controlled; Namely MTC terminal can only access within the time period that network is specified.
The transfer of data that MTC network and network side carry out is not high to requirement of real-time to transfer of data, that is: have time tolerance;
MTC terminal energy constraint, requires extremely low power consumption;
The information transmission of small data quantity is only carried out between MTC terminal and network side;
MTC terminal can manage in units of group.
An actual MTC terminal can have above-mentioned one or more characteristics.
For supporting that little bandwidth terminal equipment works in LTE system, existing scheme considers that the data area outside the existing LTE system control area within the scope of little bandwidth system bandwidth hews out separately one piece of region for placing the special down control channel of little bandwidth terminal equipment.Different according to the control area of little bandwidth system and the mapping mode of data area, have following two schemes:
Scheme one: TDM scheme
TDM(TimeDivisionMultiplex) scheme refers in the bandwidth of operation of little bandwidth system, take traditional LTE system control area in a time multiplexed manner for the control area of little bandwidth for transmission and data area and (comprise PBCH(Physicalbroadcastchannel, broadcast channel) channel, PSS(PrimarySynchronizingSignal, master sync signal), SSS channel (Secondarysynchronizationsignal, auxiliary synchronous signals)) outer other resources.Consider that the control channel of LTE system can account for the front M(M=2 or 3 or 4 of first time slot in a subframe) individual time-domain symbol, so little bandwidth system can only take N number of continued time domain symbol from M+1 (M=2 or 3 or 4) sign-on in its bandwidth range, (N is by the control format indicating channel PCFICH(Physicalcontrolformatindicatorchannel of little bandwidth system, control format indicating channel) notice, PCFICH resource mapping position in little bandwidth system control area has been fixed and network and terminal equipment are arranged, see and the following describes) as its control area.Its down control channel is carried in the control area of little bandwidth terminal equipment, such as comprise PCFICH, PHICH(Physicalhybrid-ARQindicatorchannel, HARQ indicating channel) and PDCCH(Physicaldownlinkcontrolchannel, Physical Downlink Control Channel) etc., these control channels are (such as 5MHz) distribution in the bandwidth that little bandwidth system is supported, resource distribution is illustrated in fig. 1 shown below.
Scheme two: FDM scheme
FDM(FrequencyDivisionMultiplex) scheme refers in little bandwidth system bandwidth, takies other resources except legacy system control area (comprising PBCH channel, PSS, SSS channel) for the control area of little bandwidth for transmission and data area in the mode of frequency division multiplexing.The same with TDM scheme, the control area of little bandwidth system is from M+1 (M=2 or 3 or 4) time-domain symbol of each service subframe first time slot.With TDM mode unlike, under FDM mode, control area distributes in continuous print one section of frequency band, and from time domain, the symbol after to take from M+1 (M=2 or 3 or 4) symbol all a subframe medium and small bandwidth control area.Carry its down control channel in the control area of little bandwidth terminal equipment, comprise PCFICH, PHICH and PDCCH etc., resource distribution is illustrated in fig. 2 shown below.
In above-mentioned two schemes, the control channel can supported in limited bandwidth, as PHICH channel, PDCCH channel and PUCCH(Physicaluplinksharedchannel, uplink common control channel) number of channel is more limited; Meanwhile, the resource of the service data transmission can supported also can be more limited.If only configure a little bandwidth region to use to MTC terminal in the LTE system of broadband, the demand that magnanimity MTC terminal uses network simultaneously may be can not meet; Therefore need to consider to support the problem that more MTC terminal work in LTE system simultaneously how simultaneously.

Wherein, for descending multi-frequency point data transmission plan, can at the frequency of the multiple transmission for control signal of data field configuration of existing LTE system; For up multi-frequency point data transmission plan, multiple frequency for control channel can be configured in the whole bandwidth of existing LTE system; Wherein, the data field of above-mentioned LTE system refers to LTE system PDSCH(PhysicalDownlinkSharedChannel, Physical Downlink Shared Channel) resource area.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in detail.
As shown in Figure 3, be the schematic flow sheet of the data transmission method that the embodiment of the present invention provides, this flow process can comprise:
Step 301, network equipment configure multiple frequency in the data area or up-link bandwidth of Long Term Evolution LTE system downlink system bandwidth.
Concrete, take terminal equipment as MTC terminal for example is described.In embodiments of the present invention, be configured with multiple frequency for control channel in the data area of LTE system downlink system bandwidth or up-link bandwidth, the control signal of each frequency is for dispatching the data resource on this frequency or other frequencies.The frequency point information of each frequency can notify MTC terminal by network equipment by high-level signaling or be made an appointment by network equipment and MTC terminal.Wherein, this frequency point information can include but not limited to the numbering of frequency numbering, frequency band size, frequency position and initial access frequency point.MTC terminal, according to the frequency point information received or make an appointment, initiates random access request at initial access frequency point to network equipment.
Step 302, network equipment carry out the frequency of transfer of data by signaling indicating terminal equipment.
Concrete, network equipment initially can be accessed by signaling indicating terminal equipment and the frequency of initial data transfer, can also be carried out the target frequency of frequency migration by signaling indicating terminal equipment.
Wherein, frequency migration is carried out for network side indicating terminal equipment, on the one hand, consider that each frequency may have the user of initial access at any time, in order to ensure that this frequency has sufficient these user's initialization signalings of resource provision or transfer of data to use, when on this frequency, surplus resources is lower than threshold value, network equipment needs the user of this frequency of part to migrate to other frequencies.
When on the initial access frequency point that network equipment judges this terminal equipment initiation random access request, remaining resource is lower than thresholding, network equipment sends Indication message to this terminal equipment, migrates to the more frequency of surplus resources to indicate this terminal equipment.
On the other hand, in order to save system resource, frequency utilance in raising system, when in network equipment discovery system, number of users is less, intrasystem user can focus on one or several frequency and work by network equipment.
Correspondingly, in embodiments of the present invention, network equipment detects that network demand changes and can include but not limited to one or more situations following:
Situation one, when network equipment receiving terminal apparatus preset initial access frequency point initiate random access request, and when judging that surplus resources on this initial access frequency point is lower than first threshold, network equipment sends the first Indication message to this terminal equipment, indicates described terminal equipment to migrate to appointment frequency;
Situation two, when the quantity of (as frequency A) terminal equipment of a certain frequency in network equipment judgement system is lower than Second Threshold, and the surplus resources of another frequency (as frequency B) more than the 3rd threshold value time, network equipment sends the second Indication message to the terminal equipment of frequency A, indicates the terminal equipment on this frequency to migrate to frequency B.
Step 303, terminal equipment determine according to the indication signaling that network side sends the frequency carrying out transfer of data.
Concrete, the indication signaling that terminal equipment sends according to network equipment initially accesses and initial data transfer at initial access frequency point.When the indicating terminal equipment that terminal equipment receives network equipment transmission carries out the indication signaling of frequency migration, terminal equipment migrates to appointment frequency according to the indication signaling received, and carries out transfer of data at this appointment frequency.
In the embodiment of the present invention, the configuration mode of descending multifrequency point can include but not limited to under type (wherein, being described for MTC terminal):
Mode 1, multifrequency point order arrangement mode
See Fig. 4, it is the schematic diagram of a kind of tactic multifrequency point configuration mode that the embodiment of the present invention is passed through.Support that the frequency of TDM scheme is configured to example (the frequency number of actual disposition can be determined as required, is also applicable to FDM scheme) with 2 in figure.On each little wide frequency point, the control area of little bandwidth system is mapped in the data area in existing LTE system; Each frequency is order arrangement.Wherein, in order to reduce resource fragmentation, each frequency can be consecutive order arrangement, the numbering of the frequency that order occurs can be designated as 0,1,2,3 successively ..., by high-level signaling, the information (comprising frequency numbering, frequency band size, frequency position) of each frequency notifies that MTC terminal or network equipment and MTC terminal are made an appointment known by network equipment.Wherein, this high-level signaling can include but not limited to system broadcast message or RRC signaling etc.
The back-to-back arrangement mode of mode 2, multifrequency point
See Fig. 5, the schematic diagram of the multifrequency point configuration mode of a kind of back-to-back arrangement provided for the embodiment of the present invention.On each little wide frequency point, the control area of little bandwidth system is mapped in all time-domain symbol on the partial-band of the data area in existing LTE system.The numbering of the frequency that back-to-back mode occurs can be 0,1,2,3 ..., by high-level signaling, the frequency point information of adjacent frequency notifies that MTC terminal or network equipment and MTC terminal are made an appointment by network equipment.Wherein, the control area of little bandwidth system and the size of data area can increase unidirectional expansion (spreading range be limited in MTC system bandwidth in) along with system user.In order to reduce resource fragmentation, in this multifrequency point configuration mode, adjacent two frequency bins arranges in a back-to-back fashion: i.e. the control area placed adjacent of two frequency bins, and the size of control area increases respectively to the upper and lower both direction expansion of frequency domain along with user's; Two frequency bins data area is separately expanded towards frequency domain both sides respectively outside respective control area.
Mode 3, multifrequency point compound arrangement mode
See Fig. 6, the schematic diagram of the multifrequency point configuration mode of a kind of compound arrangement provided for the embodiment of the present invention.Example is configured to 2 frequencies in figure.On each little wide frequency point, the control area of little bandwidth system is mapped in all time-domain symbol on the partial-band of the data area in existing LTE system.A pair adjacent frequency also adopts " back-to-back " mode to arrange, but the control area of this pair adjacent frequency is combined with each other and carries out resource mapping, to increase the intertexture scope of control channel (as PDCCH), promotes interleaving gain.Simultaneously, work in the PCH(PagingChannel of the user of a pair adjacent frequency, paging channel), SIB(SystemInformationBlock, system information block) etc. the PRB(PhysicalResourceBlock of public information, Physical Resource Block) resource can share.
Wherein, the maximum occurrences supposing the control area limiting adjacent a pair frequency is that PRB_Public_Max(determines according to emulation, meet the performance of most edge customer), so the frequency domain overlapping region of adjacent frequency is PRB_Control_Max+PRB_Public_Max; The frequency number 0,1,2,3 of the adjacent frequency in multiplexing of transmission mode Shared by the size of frequency band shared by the right control area original position of adjacent frequency, controlled area and/or public information transmission region, by high-level signaling, the size of frequency band notifies that MTC terminal or network equipment and MTC terminal are made an appointment by network equipment.
Mode 4, odd number frequency mixing arrangement mode
Based on the mode 2 and 3 in above-mentioned multifrequency point configuration mode, when network side configuration frequency points is the odd number being greater than 1, having a frequency can not match with other frequencies, then this frequency can configure separately, its control area can in the high side of frequency, also can in the low side of frequency.See Fig. 7, the schematic diagram of the multifrequency point configuration mode of a kind of odd number frequency mixing arrangement provided for the embodiment of the present invention; Wherein, in 2 frequency " back-to-back " modes in the configuration of 3 frequencies, and a residue single-frequency point control area is example in high frequency points side.
Corresponding with above-mentioned descending multifrequency point configuration mode, in embodiments of the present invention, the configuration mode of up multifrequency point also can comprise order arrangement mode, multifrequency point " back-to-back " arrangement mode, adjacent frequency compound arrangement mode and odd number frequency mixing arrangement mode etc., its specific implementation and descending multifrequency point configuration mode similar, describe in detail no longer one by one at this.Wherein, with descending multifrequency point configuration mode unlike, in up multifrequency point configuration mode, on each little wide frequency point, the control area of little bandwidth system can be mapped in the whole bandwidth of existing LTE system; Meanwhile, for a little wide frequency point, the control area of little bandwidth system can in both sides, data area, also can in the side of data area.For multifrequency point order arrangement mode and control area in the both sides of data area, its multifrequency point configuration mode schematic diagram can be as shown in Figure 8.

Mode 1, high-level signaling advice method
At RRC(RadioResourceControl, radio resource control) in connection establishment process, if network equipment judges that on the initial access frequency point that MTC terminal initiates random access request, remaining resource is lower than threshold value, then network equipment can need by RRCSETUP message informing MTC terminal the appointment frequency (target frequency) that migrates to.
When network equipment judges that intrasystem MTC terminal is less, reconfigure command can be connected by RRC and the MTC terminal worked on other frequencies is moved back to some frequencies or certain several frequency, to save system resource, reduce the impact on LTE system transmission.
Mode 2, physical layer signaling advice method
In this mode, MTC terminal can first at initial access frequency point (as No. 0 frequency) initiating random access procedure, and network equipment is dispatched by PDCCH channel at No. 0 frequency, the position of instruction MTC terminal data service resource.Meanwhile, PDCCH is upper can be determined by the number of little wide frequency point demand by N(N, and N bit can indicate the Nth power of 2 frequency) individual bit instruction target frequency (for dibit, 00 represents No. 0 frequency, and 01 represents No. 1 frequency) extremely to be migrated.Similar with high-level signaling advice method, when in network equipment judgement system, MTC terminal is less, the frequency points of total needs can be reduced, network equipment can cancel the transfer of data on the little wide frequency point of part, if these frequencies there are MTC terminal carrying out business transmission, then network equipment can be moved back to No. 0 frequency by PDCCH signaling MTC terminal or be concentrated to certain several frequency.
Mode 3, PDCCHorder(order) mode
When network equipment judges that MTC terminal needs to carry out working frequency points transfer, the PDCCHorder that one is carried frequency point transfer information can be sent to MTC terminal, and instruction MTC terminal initiates non-competing random access procedure at target frequency, wherein, the PRACH(PhysicalRandomAccessChannel of Stochastic accessing, Physical Random Access Channel) resource and Preamble(preamble) information can be carried in PDCCHorder.After MTC terminal receives PDCCHorder, according to the instruction of PDCCHorder, be switched to the working frequency points that network equipment is specified, and in the PRACH resource of specifying, utilize the Preamble specified to initiate non-competing random access procedure according to the requirement of network equipment.If network equipment correctly receives the Preamble information of MTC terminal transmission at target frequency, then illustrate that MTC terminal has been successfully completed frequency transfer, network equipment sends downlink acknowledge message to MTC terminal; If network equipment does not correctly receive Preamble information, network equipment needs to receive Preamble information in next PRACH resource, again PDCCHorder is sent to MTC terminal at initial access frequency point (source frequency), until the success of above-mentioned random access procedure simultaneously.
Should be realized that; above-mentioned multifrequency point configuration mode and network equipment notice MTC terminal need the mode of the frequency migrated to be only several concrete execution mode of the technical scheme that the embodiment of the present invention provides; it is not limiting the scope of the present invention; on the basis of the technical scheme provided in the embodiment of the present invention, the every other multifrequency point configuration mode that those of ordinary skill in the art obtain under the prerequisite not making creative work and network equipment notice MTC terminal need the mode of the frequency migrated to all to belong to the scope of protection of the invention.Meanwhile, the technical scheme that the embodiment of the present invention provides not merely is applicable to FDM and TDM scheme, also can be applied to other schemes.
