When the network equipment is that terminal device distributes n RB#1, what data-signal and demodulated reference signal accounted on frequency domain Sub-carrier number is 12n (that is, 12 integral multiple), that is, k=0 ..., 12n-1.For example, the case where when Fig. 3 shows n=1.
B. the first mapped mode
Specifically, under the first mapped mode, the minimum unit of the resource impact of data-signal and demodulated reference signal (in other words, unit) is different.
For demodulated reference signal, the minimum unit of the ascending resource distribution of communication system is that corresponding 12 continuous sons carry 12 × 1 RE of wave and 1 symbol, hereinafter, in order to facilitate understanding and distinguish, be denoted as RB#2, in other words, the first mapped mode In, the occupied resource of demodulated reference signal after ascending resource distribution (is carried including the son on the symbol and frequency domain in time domain Wave) quantity be above-mentioned RB#2 integral multiple.

Specifically, as shown in figure 4, carrying demodulation ginseng in above-mentioned RB#2 and RB#3 positional relationship in the time domain and RB#1 The resource unit for examining signal is similar to the positional relationship of the resource unit of carry data signals in the time domain, that is, at normal CP, RB#3 account in the time domain first 3 of each time slot and rear 3 symbols (that is, in each time slot serial number 0,1,2,4,5,6 symbol Number), RB#2 accounts for the 4th symbol symbol of serial number 3 (that is, in each time slot) of each time slot in the time domain.
Fig. 4 shows positional relationship of the RB#2 and RB#3 on frequency domain under normal CP, that is, at normal CP, shared by RB#3 Subcarrier belongs to the occupied subcarrier of RB#2.As N=6, RB#3 accounts for continuous 6 subcarriers, RB#2 on frequency domain Continuous 12 subcarriers are accounted on frequency domain.Also, the occupied carrier wave of RB#3 belongs to the occupied carrier wave of RB#2, for example, In communication system, if the start sequence number of an occupied subcarrier of RB#2 is 12n, RB#3's corresponding to the RB#2 is accounted for The start sequence number of subcarrier is 12n or 12n+6, and n is positive integer.
Since RB#3 occupies 6 subcarriers, a RB#1 can be split as two RB#3 (hereinafter, in order to Convenient for distinguishing, it is denoted as RB#3A and RB#3B) and a RB#2.Therefore, in embodiments of the present invention, two terminal devices can divide Not Shi Yong RB#3A and RB#3B transmit data-signal, and the two terminal devices can transmit demodulation reference with public above-mentioned RB#2 Signal, in this case, the network equipment can be that above-mentioned two terminal device distributes different follow in Downlink Control Information (DCI) Ring deviates (cyclic shift), so that two demodulated reference signals are orthogonal on RB#2.Then, which is carried out specifically It is bright.
Similarly, as N=3, a RB#3 occupies 3 subcarriers, and therefore, a RB#1 can be split as 4 RB# A 3 and RB#2.Therefore, in embodiments of the present invention, 4 terminal devices can transmit data using above-mentioned 4 RB#3 respectively Signal, and this 4 terminal devices can transmit demodulated reference signal with public above-mentioned RB#2, in this case, the network equipment can be with Different circulation offsets is distributed for above-mentioned 4 terminal devices, so that 4 demodulated reference signals are orthogonal on RB#2.

It should be noted that in embodiments of the present invention, it is 12 that sequence used in demodulated reference signal, which can be length, Arbitrary sequence, for example, ZC sequence.
Also, in embodiments of the present invention, the network equipment can negotiate the tool of N under the first mapped mode with each terminal device Body numerical value, alternatively, high-level signaling can also notify the specific value of N to the network equipment and each terminal device, thus, the network equipment It can be handled with each terminal device using identical N value.
It should be understood that the positional relationship of RB#2 and RB#3 in the time domain is merely illustrative under normal CP shown in Fig. 4, The present invention is not limited to this, for example, in the case where extending CP, for data-signal, the minimum of the ascending resource distribution of communication system Unit is N × 5 RE of corresponding N number of continuous subcarrier and 5 symbols, for example, in this case, RB#3 account in the time domain it is each First 2 and rear 3 symbols of time slot, RB#4 account for the 3rd symbol of each time slot in the time domain.
That is, under first mapped mode, when extending CP, when the subcarrier which be mapped to belongs to each Subcarrier corresponding to the symbol of serial number 0,1,3,4,5, the subcarrier which be mapped to belong to often in gap Subcarrier corresponding to the symbol of serial number 2 in a time slot.
More than, the ascending resource distribution condition under the first mapped mode and the second mapped mode is described, below with reference to Fig. 5 To Fig. 7, the method for the transmission upstream data for an embodiment that the present invention will be described in detail.

Optionally, which determines target mapped mode from the first mapped mode and the second mapped mode, packet It includes:
The network equipment needs the size of the first upstream data transmitted according to first terminal equipment, from the first mapped mode and In second mapped mode, target mapped mode is determined, wherein first data-signal is the first terminal equipment according to the target Mapped mode generates after carrying out resource impact processing to first upstream data.
Specifically, the network equipment can know terminal device #1 (that is, an example of first terminal equipment) at hand The transmitting uplink data period in required transmission upstream data (hereinafter, in order to facilitate understanding and explanation, be denoted as line number According to #1) size (for example, byte number that the upstream data includes).Also, the process can be similar to the prior art, here, In order to avoid repeating, description is omitted.
To which the network equipment can be mapped according to the size of upstream data #1 from above-mentioned first mapped mode and second In mode, the mapped mode of the uplink for terminal device #1 is determined, as target mapped mode.
Optionally, which is the data-signal of enhanced voice service EVS business.
Specifically, enhanced voice service (EVS, Enhanced Voice Service) has determined by as next For speech coding schemes, EVS under typical scene is substantially smaller in size than traditional AMR data in the data packet of air interface transmission Packet.
To if upstream data #1 is enhanced voice service (EVS, Enhanced Voice Service) voice number According to lesser data packets such as packets, then the transmission of upstream data #1 can be completed by only needing a small number of subcarriers just, and therefore, network is set It is standby to can choose the first mapped mode as above-mentioned target mapped mode.
It should be noted that EVS business listed above is only the exemplary illustration of the lesser business of data packet, the present invention It's not limited to that, and other lesser business of data packet are able to use above-mentioned first mapped mode and carry out at resource impact Reason.
For another example needing more subcarrier ability if upstream data #1 is the biggish data packets such as video traffic The transmission of upstream data #1 is enough completed, therefore, the network equipment can choose the second mapped mode as above-mentioned target and map mould Formula.
It should be understood that the network equipment listed above determines that the method and process of target mapped mode are merely illustrative, The present invention is not limited to this, for example, the network equipment can also determine the channel quality between the network equipment and terminal device #1, If channel quality is preferable, terminal device #1 is able to use high order modulation coding mode and carries out coded treatment to upstream data, To which code block generated is smaller, it is only necessary to which a small number of subcarriers just can complete the transmission of upstream data #1, in this case, net Network equipment can choose the first mapped mode as above-mentioned target mapped mode.
In embodiments of the present invention, the parcel that the business belonging to above-mentioned upstream data #1 belongs to such as EVS business passes In the case where defeated business, the network equipment can also further determine that the quantity of the occupied subcarrier of upstream data #1, and then really Surely the quantity of the above-mentioned RB#3 for its distribution is needed.
Optionally, the size for the first upstream data which needs to transmit according to first terminal equipment, from first In mapped mode and the second mapped mode, target mapped mode is determined, comprising:
The network equipment determines subcarrier required for the first upstream data of transmission according to the size of the first upstream data Quantity M；
As M≤N, network equipment determination uses first mapped mode as the target mapped mode；Or
Work as M > N, and when 12 (i-1) < M≤12i-N, network equipment determination uses first mapped mode as this Target mapped mode, i are positive integer.
Specifically, the occupied number of subcarriers M of upstream data #1 is less than or equal to 6 as N=6, then one is only needed A RB#3 just can complete the transmission to upstream data #1, and therefore, the network equipment, which can determine, makees above-mentioned first mapped mode For the target mapped mode for terminal device #1.
Similarly, as N=4, the occupied number of subcarriers M of upstream data #1 is less than or equal to 4, then only needs one RB#3 just can complete the transmission to upstream data #1, therefore, the network equipment can determine using above-mentioned first mapped mode as For the target mapped mode of terminal device #1.
As N=3, the occupied number of subcarriers M of upstream data #1 is less than or equal to 3, then only needs a RB#3 just The transmission to upstream data #1 can be completed, therefore, the network equipment can be determined using above-mentioned first mapped mode as eventually The target mapped mode of end equipment #1.
As N=2, the occupied number of subcarriers M of upstream data #1 is less than or equal to 2, then only needs a RB#3 just The transmission to upstream data #1 can be completed, therefore, the network equipment can be determined using above-mentioned first mapped mode as eventually The target mapped mode of end equipment #1.
For another example if the occupied number of subcarriers M of upstream data #1 is greater than 6, and needing even number as N=6 RB#3 can complete the transmission to upstream data #1, then the quantity of required frequency domain resource is still the integral multiple of RB#1, this In the case of, the network equipment can be determined using above-mentioned second mapped mode as the target mapped mode for being directed to terminal device #1.
On the other hand, as N=6, if the occupied number of subcarriers M of upstream data #1 is greater than 12, and odd number is needed A RB#3 can complete the transmission to upstream data #1 (that is, M > N, and M=12i+6), then required for frequency domain resource quantity It is not the integral multiple of RB#1, in this case, the network equipment can be determined using above-mentioned first mapped mode as terminal device # 1 target mapped mode.
For another example if the occupied number of subcarriers M of upstream data #1 is greater than 3, and needing 4 integer as N=3 A RB#3 can complete the transmission to upstream data #1 again, then the quantity of required frequency domain resource is still the integer of RB#1 Times, in this case, the network equipment, which can be determined, maps mould for above-mentioned second mapped mode as the target for terminal device #1 Formula.
On the other hand, as N=3, if the occupied number of subcarriers M of upstream data #1 is greater than 3, and non-4 are needed Integral multiple RB#3 can complete the transmission to upstream data #1 (that is, M > N, and M=12i+6 or M=12i+9), then required for Frequency domain resource quantity be not RB#1 integral multiple, in this case, the network equipment can be determined above-mentioned first mapped mode As the target mapped mode for being directed to terminal device #1.
For another example if the occupied number of subcarriers M of upstream data #1 is greater than 4, and needing 3 integer as N=4 A RB#3 can complete the transmission to upstream data #1 again, then the quantity of required frequency domain resource is still the integer of RB#1 Times, in this case, the network equipment, which can be determined, maps mould for above-mentioned second mapped mode as the target for terminal device #1 Formula.
On the other hand, as N=4, if the occupied number of subcarriers M of upstream data #1 is greater than 4, and non-3 are needed Integral multiple RB#3 can complete the transmission to upstream data #1, then the quantity of required frequency domain resource is not the integer of RB#1 Times (that is, M > N, and M=12i+4 or M=12i+8), in this case, the network equipment can be determined above-mentioned first mapped mode As the target mapped mode for being directed to terminal device #1.
For another example if the occupied number of subcarriers M of upstream data #1 is greater than 2, and needing 6 integer as N=2 A RB#3 can complete the transmission to upstream data #1 again, then the quantity of required frequency domain resource is still the integer of RB#1 Times, in this case, the network equipment, which can be determined, maps mould for above-mentioned second mapped mode as the target for terminal device #1 Formula.
On the other hand, as N=2, if the occupied number of subcarriers M of upstream data #1 is greater than 2, and non-6 are needed Integral multiple RB#3 can complete the transmission to upstream data #1 (that is, M > N, and M=12i+2, M=12i+4, M=12i+6, M =12i+8 or M=12i+10), then the quantity of required frequency domain resource is not the integral multiple of RB#1, in this case, network is set It is standby to determine using above-mentioned first mapped mode as the target mapped mode for being directed to terminal device #1.
After the determining target mapped mode for terminal device #1 as described above, the network equipment can be set to the terminal Standby #1, which is sent, to be used to indicate the instruction information of the target mapped mode and (hereinafter, in order to facilitate understanding and distinguishing, is denoted as instruction letter Cease #1).
In embodiments of the present invention, two marks and two mappings can be stored in advance in terminal device and the network equipment Mapping relations between mode, for example, 1 can be corresponding with the first mapped mode, 0 can be corresponding with the second mapped mode. To which, the network equipment can pass through bit corresponding to the instruction information #1 that will carry in the message for being sent to terminal device #1 (in other words, marker) sets 1, to identify the selected target mapped mode of the network equipment as the first mapped mode, also, network Equipment can be by bit corresponding to the instruction information #1 that will carry in the message for being sent to terminal device #1 (in other words, Marker) 0 is set, it is the second mapped mode to identify the selected target mapped mode of the network equipment.
In addition, in embodiments of the present invention, which can be carried on the network equipment and be sent to terminal device Control information, for example, in Downlink Control Information (DCI, Downlink Control Information).
Also, in embodiments of the present invention, the network equipment can also carry out scheduling of resource to terminal device #1, to notify end End equipment #1 carries out resource impact and handles used running time-frequency resource.
Terminal device #1, can be from above-mentioned first mapped mode and the second mapped mode after receiving instruction information #1 In, mapped mode corresponding with the instruction information #1 is selected, carries out mesh used in resource impact as to upstream data #1 Mark mapped mode.
Thereafter, terminal device #1 can carry out resource based on target mapped mode and reflect according to the scheduling of resource of the network equipment Penetrate processing (handling including the resource impact processing for data-signal and for the resource impact of demodulated reference signal).
For example, Fig. 6 is shown as N=6, the method for terminal device #1 transmission upstream data according to an embodiment of the present invention The schematic diagram of demodulated reference signal and data-signal for carrying out resource impact processing and obtaining.As shown in fig. 6, in normal CP Under, in time slot 0 and time slot 1, corresponding 12 subcarriers of the demodulated reference signal of terminal device #1, that is, in Fig. 6, subcarrier #0 ~subcarrier #11, also, corresponding 6 subcarriers of data-signal, that is, in Fig. 6, subcarrier #0~subcarrier #5.Such as Fig. 6 institute Show, it is a part that demodulated reference signal corresponds to subcarrier that data-signal, which corresponds to subcarrier, and in other words, the corresponding son of data-signal carries Wave belongs to demodulated reference signal and corresponds to subcarrier.
It should be noted that data-signal shown in fig. 6, which can be terminal device #1, needs to be sent to the complete of the network equipment Portion's data-signal it is some or all, the present invention is simultaneously not particularly limited.For example, when upstream data #1 needs 3 RB#3 to hold When load, need to distribute 24 subcarriers for terminal device #1 to carry three data-signals and two demodulated reference signals.And And 12 subcarriers that two RB#3 corresponding to the first two data-signal are occupied correspond to corresponding to first demodulated reference signal 12 subcarriers occupying of RB#2,6 subcarriers that RB#3 corresponding to the last one data-signal is occupied are second corresponding Preceding 6 subcarriers in 12 subcarriers that RB#2 corresponding to demodulated reference signal is occupied.
Optionally, if the target mapped mode be first mapped mode, and the W subcarrier carry this first Position in the first time slot and the second time slot of first subframe of data-signal is identical, then in first time slot, the T subcarrier Subcarrier including being located at first position in W subcarrier, in second time slot, which includes in the W subcarrier Subcarrier positioned at the second position, the first position are different with the second position.
That is, in embodiments of the present invention, in two time slots of a subframe, if W of carrying demodulated reference signal Son is identical in the position of wave, then the position of T subcarrier of carry data signals in two time slots can be made different, that is, can be with Handle for the resource impact of data-signal using frequency-hopping mode.Specifically, if terminal device #1 is reflected using first Emission mode carries out resource impact, and occupied sub-carrier number T (for example, 6) the < demodulation reference letter of the data-signal ultimately generated Number occupied sub-carrier number W (for example, 12), then for example, in N=6, upstream data #1 has only taken up a RB#3, this In the case of, terminal device #1 is used only a RB#2 and transmits demodulated reference signal.Fig. 7 is shown as N=6, terminal device #1 The method of transmission upstream data according to an embodiment of the present invention carries out resource impact processing and the demodulated reference signal and number that obtain It is believed that number another schematic diagram.As shown in fig. 7, in time slot 0 (an example of the first time slot of the first subframe), the solution of terminal device #1 Adjust corresponding 12 subcarriers of reference signal, that is, in Fig. 7, subcarrier #0~subcarrier #11, also, data-signal is 6 corresponding Subcarrier, that is, in Fig. 7, subcarrier #0~subcarrier #5.In time slot 1 (an example of the second time slot of first subframe), eventually Corresponding 12 subcarriers of the demodulated reference signal of end equipment #1, that is, in Fig. 7, subcarrier #0~subcarrier #11, also, data Signal corresponds to 6 subcarriers, that is, in Fig. 7, subcarrier #6~subcarrier #11.As shown in fig. 7, data-signal corresponds to subcarrier It is a part that demodulated reference signal corresponds to subcarrier, in other words, data-signal corresponds to subcarrier and belongs to demodulated reference signal pair Answer subcarrier.
In embodiments of the present invention, since data-signal corresponds to different subcarriers in different time-gap, diversity can be utilized Gain, for example, the channel quality corresponding to subcarrier #0~subcarrier #5 is poor and subcarrier #6~subcarrier #11 corresponding to Channel quality it is higher when, can be avoided data-signal always in second-rate transmission, so as to improve communication matter Amount.
It should be understood that frequency-hopping mode listed above is only an example for being directed to the resource impact of data-signal, the present invention is not It is defined in this, for example, in embodiments of the present invention, which can also be identical with the second position.
Optionally, if the target mapped mode be first mapped mode, the W subcarrier carry this first Position in the first time slot and the second time slot of second subframe of demodulated reference signal is different.
Specifically, in embodiments of the present invention, the resource for demodulated reference signal can also be carried out with frequency-hopping mode Mapping processing, that is, in time slot 0 (an example of the first time slot of the second subframe), W son for carrying first demodulated reference signal is carried Wave is for example, subcarrier #0~subcarrier #11 carries first demodulation in time slot 1 (an example of the second time slot of the second subframe) W subcarrier of reference signal is for example subcarrier #12~subcarrier #23.
In embodiments of the present invention, it since demodulated reference signal corresponds to different subcarriers in different time-gap, can utilize Diversity gain, for example, the channel quality corresponding to subcarrier #0~subcarrier #11 is poor and subcarrier #12~subcarrier #23 When corresponding channel quality is higher, demodulated reference signal can be avoided always in second-rate transmission, so as to Improve communication quality.
