Description
Technical field
The present invention relates to wireless communication field, relate in particular to a kind of data transmission method and equipment.
Background technology
M2M(Machine-to-machine, machinery compartment) communication is as a kind of novel communication theory, its objective is that the communication technology with number of different types organically combines, as: machine is to machine communication, machine control communication, man-machine interaction communication, mobile interconnected communication, thus the development of promotion social production and life style.
Current mobile communications network designs at interpersonal communication, as determining etc. of: network capacity.Support little bandwidth system communication just need be optimized according to the characteristics of the little bandwidth system communication mechanism to mobile communication system if wish to utilize mobile communications network, in order to can not be subjected to or be subjected to realize little bandwidth system communication better under the less situation about influencing to traditional person to person's communication.

The MTC terminal can be that unit manages with the group.
The MTC terminal of a reality can have above-mentioned one or more characteristics.
For supporting little bandwidth terminals equipment to work in the LTE system, existing scheme considers that the overseas data area, existing LTE system control area in little bandwidth system bandwidth range hews out the down control channel that a zone is used for placing little bandwidth terminals device-specific separately.Different according to the mapping mode of the control area of little bandwidth system and data area have following two kinds of schemes:
Scheme one: TDM scheme
TDM(Time Division Multiplex) scheme refers in the bandwidth of operation of little bandwidth system, being used for the control area of little bandwidth for transmission and data area takies territory, traditional LTE system control area in time-multiplexed mode and (comprises PBCH(Physical broadcast channel, broadcast channel) channel, PSS(Primary Synchronizing Signal, master sync signal), Wai other resources SSS channel (Secondary synchronization signal, auxiliary synchronous signals)).Consider that the control channel of LTE system can account for the preceding M(M=2 or 3 or 4 of first time slot in the subframe) individual time-domain symbol, (N is by the control format indicating channel PCFICH(Physical control format indicator channel of little bandwidth system so little bandwidth system can only take N continued time domain symbol from M+1 (M=2 or 3 or 4) sign-on in its bandwidth range, the control format indicating channel) notice, PCFICH in little bandwidth system control area resource mapping position fixing and network and terminal equipment arrange, face is described as follows) as its control area.Carry its down control channel in the control area of little bandwidth terminals equipment, for example comprise PCFICH, PHICH(Physical hybrid-ARQ indicator channel, the HARQ indicating channel) and PDCCH(Physical downlink control channel, Physical Downlink Control Channel) etc., these control channels (for example 5MHz) in the bandwidth that little bandwidth system is supported distribute, and resource distribution is illustrated in fig. 1 shown below.

Mode 3, the compound arrangement mode of multifrequency point
Referring to Fig. 6, the schematic diagram of the multifrequency point configuration mode of a kind of compound arrangement that provides for the embodiment of the invention.Be configured to example with 2 frequencies among the figure.On each little bandwidth frequency, the control area of little bandwidth system is mapped in all time-domain symbol on the partial-band that has the data area in the LTE system now.Adjacent a pair of frequency also adopts " back-to-back " mode to arrange, but the control area of this adjacent a pair of frequency is combined with each other and carries out resource mapping, to increase the scope that interweaves of control channel (as PDCCH), promotes the gain that interweaves.Simultaneously, work in the user's of adjacent a pair of frequency PCH(Paging Channel, paging channel), SIB(System Information Block, system information block) etc. the PRB(Physical Resource Block of public information, Physical Resource Block) resource can share.
Wherein, the maximum occurrences of the control area of a pair of frequency that restriction of assumption is adjacent is that PRB_Public_Max(determines according to emulation, satisfy the performance of edge customer), to overlap the zone be PRB_Control_Max+PRB_Public_Max to the frequency domain of adjacent frequency so; The frequency numbering 0,1,2,3 of the adjacent frequency in the compound transmission means Right control area original position, the size of the shared frequency band in controlled area and/or the size of the shared frequency band of public information transmission region of adjacent frequency notifies MTC terminal or network equipment and MTC terminal to make an appointment by network equipment by high-level signaling.

When network equipment is judged intrasystem MTC terminal more after a little while, can connect reconfigure command by RRC will move back to some frequencies or certain several frequency in the MTC terminal that other frequencies are worked, and to save system resource, reduce the influence to the LTE system transmissions.
Mode 2, physical layer signaling advice method
Under this mode, the MTC terminal can be initiated random access procedure at initial access frequency point (as No. 0 frequency) earlier, and network equipment is dispatched by the PDCCH channel at No. 0 frequency, the position of indication MTC terminal data service resources.Simultaneously, PDCCH is last can to determine that by the number of little bandwidth frequency demand the N bit can be indicated a Nth power frequency of 2 by N(N) individual bit indication target frequency (be example with the dibit, No. 0 frequency of 00 expression, 01 represents No. 1 frequency) extremely to be migrated.Similar with the high-level signaling advice method, the MTC terminal more after a little while in network equipment judgement system, can reduce the frequency points of total needs, network equipment can be cancelled the transfer of data on the little bandwidth frequency of part, if there is on these frequencies the MTC terminal to transmit carrying out business, then network equipment can be moved back to No. 0 frequency or is concentrated to certain several frequency by PDCCH signaling MTC terminal.
Mode 3, PDCCH order(order) mode
When network equipment judges that the MTC terminal need be carried out the working frequency points transfer, can send a PDCCH order who carries frequency point transfer information to the MTC terminal, and indication MTC terminal is initiated non-competing random access procedure at the target frequency, wherein, the PRACH(Physical Random Access Channel of Jie Ruing at random, Physical Random Access Channel) resource and Preamble(preamble) information can be in being carried at PDCCH order.After the MTC terminal receives PDCCH order, indication according to PDCCH order, switch to the working frequency points of network equipment appointment, and utilize the Preamble of appointment to initiate non-competing random access procedure according to the requirement of network equipment in the PRACH of appointment resource.If network equipment correctly receives the Preamble information that the MTC terminal sends at the target frequency, illustrate that then the MTC terminal has completed successfully frequency and shifted, network equipment sends downlink acknowledge message to the MTC terminal; If network equipment does not correctly receive Preamble information, network equipment need receive Preamble information in next PRACH resource, again the MTC terminal is sent PDCCH order at initial access frequency point (source frequency) simultaneously, until above-mentioned random access procedure success.
Should be realized that; the mode of the frequency that above-mentioned multifrequency point configuration mode and network equipment notice MTC terminal need migrate to only is several concrete execution mode of the technical scheme that provides of the embodiment of the invention; it is not the restriction to protection range of the present invention; on the basis of the technical scheme that the embodiment of the invention provides, the mode of the frequency that the every other multifrequency point configuration mode that those of ordinary skills obtain under the prerequisite of not making creative work and network equipment notice MTC terminal need migrate to all belongs to the scope of protection of the invention.Simultaneously, the technical scheme that the embodiment of the invention provides not merely is applicable to FDM and TDM scheme, also can be applied to other schemes.
