In preset time, the network equipment 102, terminal unit 116 or terminal unit 122 can be radio communication transmitter and/or radio communication receiver.When sending out data, data can be encoded for transmission by radio communication transmitter.Specifically, radio communication transmitter can obtain (such as generate, receive from other communicator or preservation etc. in memory) and to pass through channel and send the data bit of the some to radio communication receiver.This data bit can be included in the transmission block (or multiple transmission block) of data, and transmission block can be segmented to produce multiple code block, and this data bit generates data signal (that is, modulation symbol) after bit mapping processes.

Further, can also spread out of between the network equipment 102 and terminal unit 16 or terminal unit 122 demodulated reference signal (or, it is also possible to be called reference signal) to carry out channel estimating.

The running time-frequency resource that above-mentioned data signal and demodulated reference signal are provided by communication system is transmitted.

Fig. 2 is the schematic diagram of the running time-frequency resource dividing mode of the embodiment of the present invention.As shown in Figure 2, in time domain, the length of one radio frames is 10ms, comprises 10 subframes, and the length of each subframe is 1ms, each subframe comprises 2 time slots, when using normal Cyclic Prefix (CP, CyclicPrefix), each time slot comprises 7 symbols, when using extended cyclic prefix, each time slot comprises 6 symbols.

Further, as in figure 2 it is shown, on frequency domain, the frequency domain resource that communication system provides comprises multiple subcarrier, and a subcarrier under a symbol is called a Resource Unit (RE, ResourceElement).

The method of transmission upstream data according to embodiments of the present invention, it is applied to the communication system using the first mapped mode or the second mapped mode to carry out resource mapping process, under this first mapped mode, the quantity of the subcarrier that the quantity of the subcarrier that data signal be mapped to and demodulated reference signal be mapped to is different, and the subcarrier that this data signal be mapped to belongs to the subcarrier that this demodulated reference signal be mapped to, this data signal is mapped on integral multiple the subcarrier of N, this demodulated reference signal is mapped on integral multiple the subcarrier of 12, N is following any value: 2, 3, 4 or 6, under this second mapped mode, quantity and the position of the subcarrier that data signal be mapped to demodulated reference signal are identical, and this data signal and this demodulated reference signal are mapped on integral multiple the subcarrier of 12.

Below, respectively the ascending resource under the first mapped mode and the second mapped mode is mapped situation to illustrate.

A. the second mapped mode

Specifically, in the second mapped mode, the minimum unit of the ascending resource distribution of communication system is the Resource Block (RB, ResourceBlock) of a first kind, below, for the ease of understanding and distinguishing, it is denoted as RB#1, in other words, in the second mapped mode, the quantity of data signal after ascending resource distribution and all shared resource (including the symbol in time domain and the subcarrier on frequency domain) of demodulated reference signal is the integral multiple of above-mentioned RB#1.Fig. 3 is under the second mapped mode of the embodiment of the present invention, the schematic diagram of the minimum unit of ascending resource distribution, as shown in Figure 3, for instance, during normal CP, a RB#1 includes 12 × 7 RE of corresponding 12 continuous print subcarriers and 1 time slot.

On RB#1, it is possible to carry data signals and reference signal, and, the minimum unit (in other words, unit) distributed for the ascending resource of data signal and reference signal is identical.

As it is shown on figure 3, data signal be mapped to a RB#1 be numbered (k, l₁) RE on, wherein, k represents on frequency domain the sequence number of shared subcarrier, l₁Represent the sequence number of symbol shared in time domain, l₁=0,1,2,4,5,6 (when using normal CP) or l₁=0,1,3,4,5 (when using extension CP).

Further, what demodulated reference signal was mapped to same RB#1 is numbered (k, l₂) RE on, wherein l₂=3 (when using normal CP) or l₂=2 (when using extension CP).

When the network equipment is terminal unit n RB#1 of distribution, the sub-carrier number that data signal and demodulated reference signal account on frequency domain is 12n (that is, the integral multiple of 12), i.e. k=0 ..., 12n-1.Such as, situation when Fig. 3 illustrates n=1.

B. the first mapped mode

Specifically, under the first mapped mode, the minimum unit (in other words, unit) that the resource of data signal and demodulated reference signal maps is different.

For demodulated reference signal, the minimum unit of the ascending resource distribution of communication system is 12 × 1 RE of corresponding 12 continuous print subcarriers and 1 symbol, below, for the ease of understanding and distinguishing, it is denoted as RB#2, in other words, in the first mapped mode, the quantity of the resource (including the symbol in time domain and the subcarrier on frequency domain) that demodulated reference signal after ascending resource distribution is all shared is the integral multiple of above-mentioned RB#2.

Under normal CP, for data signal, the minimum unit of the ascending resource distribution of communication system is N × 6 RE of corresponding N number of continuous print subcarrier and 6 symbols, below, for the ease of understanding and distinguishing, it is denoted as RB#3, in other words, in first mapped mode, the quantity of the resource (including the symbol in time domain and the subcarrier on frequency domain) that data signal after ascending resource distribution is all shared is the integral multiple of above-mentioned RB#3.Wherein, the value of N can be 2,3,4 or 6, it is possible to needs according to system and selects to set, as long as guaranteeing that the network equipment is identical with the N selected by terminal unit, below, for the ease of understanding and illustrating, for N=6, illustrates.

And, in embodiments of the present invention, the minimum unit of the ascending resource distribution of the demodulated reference signal under the first mapped mode can be identical with the minimum unit of the ascending resource of the demodulated reference signal under the second mapped mode distribution, and the minimum unit of the ascending resource distribution of the data signal under the first mapped mode is different with the minimum unit of the ascending resource of the data signal under the second mapped mode distribution.

Below, in conjunction with Fig. 4, the position relationship between RB#2 and RB#3 is described.

Fig. 4 is under the first mapped mode of the embodiment of the present invention, the schematic diagram of the minimum unit of ascending resource distribution, and, in the embodiment shown in fig. 4, N=6.

Alternatively, under this first mapped mode, when normal cyclic prefix CP, it is the subcarrier corresponding to the symbol of 0,1,2,4,5,6 that the subcarrier that this data signal be mapped to belongs to sequence number in each time slot, and it is the subcarrier corresponding to the symbol of 3 that the subcarrier that this demodulated reference signal be mapped to belongs to sequence number in each time slot.

Specifically, as shown in Figure 4, above-mentioned RB#2 and RB#3 position relationship in time domain is similar to the Resource Unit of carry data signals position relationship in time domain to the Resource Unit carrying demodulated reference signal in RB#1, namely, under normal CP, (namely RB#3 accounts for front 3 and rear 3 symbols of each time slot in time domain, in each time slot, sequence number is the symbol of 0,1,2,4,5,6), RB#2 accounts for the 4th symbol (that is, in each time slot, sequence number is the symbol of 3) of each time slot in time domain.

Fig. 4 illustrates RB#2 and RB#3 position relationship on frequency domain under normal CP, i.e. under normal CP, and the subcarrier shared by RB#3 belongs to the subcarrier shared by RB#2.As N=6, RB#3 accounts for 6 subcarriers of continuous print on frequency domain, and RB#2 accounts for 12 subcarriers of continuous print on frequency domain.Further, the carrier wave shared by RB#3 belongs to the carrier wave shared by RB#2, for instance, in a communications system, if the start sequence number of the subcarrier shared by a RB#2 is 12n, then the start sequence number of the subcarrier taken of the RB#3 corresponding to this RB#2 is 12n or 12n+6, n is positive integer.

Owing to a RB#3 takies 6 subcarriers, therefore, a RB#1 can be split as two RB#3 (following, for the ease of distinguishing, to be denoted as a RB#3A and RB#3B) and RB#2.Therefore, in embodiments of the present invention, two terminal units can use RB#3A and RB#3B to transmit data signal respectively, and the two terminal unit can transmit demodulated reference signal by public above-mentioned RB#2, in this situation, the network equipment can offset (cyclicshift) for the circulation that the distribution of above-mentioned two terminal unit is different in Downlink Control Information (DCI), so that two demodulated reference signals are orthogonal on RB#2.Subsequently, this process is described in detail.

Similarly, as N=3, a RB#3 takies 3 subcarriers, and therefore, a RB#1 can be split as a 4 RB#3 and RB#2.Therefore, in embodiments of the present invention, 4 terminal units can use above-mentioned 4 RB#3 to transmit data signal respectively, and these 4 terminal units can transmit demodulated reference signal by public above-mentioned RB#2, in this situation, the network equipment can be the circulation skew that above-mentioned 4 terminal units distribution is different, so that 4 demodulated reference signals are orthogonal on RB#2.

As N=4, a RB#3 takies 4 subcarriers, and therefore, a RB#1 can be split as a 3 RB#3 and RB#2.Therefore, in embodiments of the present invention, 3 terminal units can use above-mentioned 3 RB#3 to transmit data signal respectively, and these 3 terminal units can transmit demodulated reference signal by public above-mentioned RB#2, in this situation, the network equipment can be the circulation skew that above-mentioned 3 terminal units distribution is different, so that 3 demodulated reference signals are orthogonal on RB#2.

It should be noted that in embodiments of the present invention, the sequence that demodulated reference signal uses can be length is the arbitrary sequence of 12, for instance, ZC sequence.

And, in embodiments of the present invention, the network equipment can consult the concrete numerical value of N under the first mapped mode with each terminal unit, or, high-level signaling can also notify the concrete numerical value of N to the network equipment and each terminal unit, thus, the N value that the network equipment can be identical with each terminal unit use processes.

It should be understood that, under normal CP shown in Fig. 4, RB#2 and RB#3 position relationship in time domain is merely illustrative, and the present invention is not limited to this, such as, under extension CP, for data signal, the minimum unit of the ascending resource distribution of communication system is N × 5 RE of corresponding N number of continuous print subcarrier and 5 symbols, such as, in this situation, RB#3 accounts for front 2 and rear 3 symbols of each time slot in time domain, and RB#4 accounts for the 3rd symbol of each time slot in time domain.

Namely, under this first mapped mode, when extending CP, it is the subcarrier corresponding to the symbol of 0,1,3,4,5 that the subcarrier that this data signal be mapped to belongs to sequence number in each time slot, and it is the subcarrier corresponding to the symbol of 2 that the subcarrier that this demodulated reference signal be mapped to belongs to sequence number in each time slot.

Above, describe the ascending resource distribution condition under the first mapped mode and the second mapped mode, below in conjunction with Fig. 5 to Fig. 7, the method describing the transmission upstream data of one embodiment of the invention in detail.

Fig. 5 illustrates the indicative flowchart of the method 200 transmitting upstream data according to an embodiment of the invention described from network equipment angle, as it is shown in figure 5, the method 200 includes:

S210, the network equipment is from this first mapped mode and this second mapped mode, it is determined that target mapped mode；

S220, this network equipment sends the information for indicating this target mapped mode to first terminal equipment；

S230, this network equipment receives the first demodulated reference signal and the first data signal that generate after this first terminal equipment carries out resource mapping process according to this target mapped mode, wherein, this first demodulated reference signal is corresponding with W subcarrier, T subcarrier in W subcarrier of this first data signal and this is corresponding, and W is the integral multiple of 12；

Alternatively, this network equipment is from the first mapped mode and the second mapped mode, it is determined that target mapped mode, including:

The network equipment needs the size of the first upstream data of transmission according to first terminal equipment, from the first mapped mode and the second mapped mode, determine target mapped mode, wherein, this first data signal is to generate after this first upstream data is carried out resource mapping process according to this target mapped mode by this first terminal equipment.

Specifically, (namely the network equipment can know terminal unit #1, one example of first terminal equipment) within the transmitting uplink data cycle on the horizon, the upstream data of required transmission is (following, for the ease of understanding and explanation, be denoted as upstream data #1) size (byte number that such as, this upstream data includes).Further, this process can be similar to prior art, and here, in order to avoid repeating, description is omitted.

Thus, the network equipment can according to the size of this upstream data #1, from above-mentioned first mapped mode and the second mapped mode, it is determined that for the mapped mode of the uplink of terminal unit #1, as target mapped mode.

Alternatively, this first data signal is the data signal of enhancement mode voice service EVS business.

Specifically, enhancement mode voice service (EVS, EnhancedVoiceService) it has been determined that be taken as speech coding schemes of future generation, the EVS under typical scene air interface transmission packet be substantially smaller in size than traditional AMR packet.

Thus, it is enhancement mode voice service (EVS if up data #1, EnhancedVoiceService) packet that VoP etc. are less, then only need minority subcarrier just can complete the transmission of this upstream data #1, therefore, the network equipment can select 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 less business of packet, the present invention is not limited to this, and the business that other packet is less all can use above-mentioned first mapped mode to carry out resource mapping process.

Again such as, being the bigger packets such as video traffic if up data #1, then need more subcarrier can complete the transmission of this upstream data #1, therefore, the network equipment can select the second mapped mode as above-mentioned target mapped mode.

It should be understood that, the network equipment listed above determines that the method for target mapped mode and process are merely illustrative, the present invention is not limited to this, such as, the network equipment is it may also be determined that channel quality between the network equipment and terminal unit #1, if channel quality is better, then terminal unit #1 can use high order modulation coded system to be encoded upstream data processing, thus the code block generated is less, only need minority subcarrier just can complete the transmission of this upstream data #1, in this situation, the network equipment can select the first mapped mode as above-mentioned target mapped mode.

In embodiments of the present invention, when the business belonging to above-mentioned upstream data #1 belongs to the parcel transport service of such as EVS business, the network equipment can also further determine that the quantity of the subcarrier shared by upstream data #1, and then determines the quantity needing the above-mentioned RB#3 for its distribution.

Alternatively, this network equipment needs the size of the first upstream data of transmission according to first terminal equipment, from the first mapped mode and the second mapped mode, it is determined that target mapped mode, including:

This network equipment size according to the first upstream data, it is determined that transmit the quantity M of subcarrier required for the first upstream data；

As M≤N, this network equipment determines that this first mapped mode of use is as this target mapped mode；Or

Work as M > N, and during 12 (i-1) < M≤12i-N, this network equipment determines that this first mapped mode of use is as this target mapped mode, and i is positive integer.

Specifically, as N=6, the number of subcarriers M shared by upstream data #1 less than or equal to 6, then only needs a RB#3 just can complete the transmission to upstream data #1, therefore, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

Similarly, as N=4, the number of subcarriers M shared by upstream data #1 less than or equal to 4, then only needs a RB#3 just can complete the transmission to upstream data #1, therefore, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

As N=3, number of subcarriers M shared by upstream data #1 is less than or equal to 3, then only needing a RB#3 just can complete the transmission to upstream data #1, therefore, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

As N=2, number of subcarriers M shared by upstream data #1 is less than or equal to 2, then only needing a RB#3 just can complete the transmission to upstream data #1, therefore, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

Again such as, as N=6, if up the number of subcarriers M shared by data #1 more than 6, and need even number RB#3 can complete the transmission to upstream data #1, the quantity of then required frequency domain resource remains the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned second mapped mode as the target mapped mode for terminal unit #1.

On the other hand, as N=6, if up the number of subcarriers M shared by data #1 more than 12, and need odd number RB#3 can complete the transmission to upstream data #1 (namely, M > N, and M=12i+6), then the quantity of required frequency domain resource is not the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

Again such as, as N=3, if up the number of subcarriers M shared by data #1 more than 3, and need integral multiple the RB#3 of 4 can complete the transmission to upstream data #1, the quantity of then required frequency domain resource remains the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned second mapped mode as the target mapped mode for terminal unit #1.

On the other hand, as N=3, if up the number of subcarriers M shared by data #1 more than 3, and need integral multiple the RB#3 of non-4 can complete the transmission to upstream data #1 (namely, M > N, and M=12i+6 or M=12i+9), then the quantity of required frequency domain resource is not the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

Again such as, as N=4, if up the number of subcarriers M shared by data #1 more than 4, and need integral multiple the RB#3 of 3 can complete the transmission to upstream data #1, the quantity of then required frequency domain resource remains the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned second mapped mode as the target mapped mode for terminal unit #1.

On the other hand, as N=4, if up the number of subcarriers M shared by data #1 more than 4, and need integral multiple the RB#3 of non-3 can complete the transmission to upstream data #1, the quantity of then required frequency domain resource is not the integral multiple (that is, M > N, and M=12i+4 or M=12i+8) of RB#1, in this situation, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

Again such as, as N=2, if up the number of subcarriers M shared by data #1 more than 2, and need integral multiple the RB#3 of 6 can complete the transmission to upstream data #1, the quantity of then required frequency domain resource remains the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned second mapped mode as the target mapped mode for terminal unit #1.

On the other hand, as N=2, if up the number of subcarriers M shared by data #1 more than 2, and need integral multiple the RB#3 of non-6 can complete the transmission to upstream data #1 (namely, M > N, and M=12i+2, M=12i+4, M=12i+6, M=12i+8 or M=12i+10), the quantity of then required frequency domain resource is not the integral multiple of RB#1, in this situation, the network equipment may determine that above-mentioned first mapped mode as the target mapped mode for terminal unit #1.

Determined as described above for the target mapped mode of terminal unit #1 after, the network equipment can send the instruction information (following, for the ease of understanding and distinguishing, to be denoted as instruction information #1) for indicating this target mapped mode to this terminal unit #1.

In embodiments of the present invention, the mapping relations between two marks and two mapped modes can be prestored in terminal unit and the network equipment, for instance, 1 can be corresponding with the first mapped mode, and 0 can be corresponding with the second mapped mode.Thus, the network equipment can pass through to be sent in the message of terminal unit #1 the bit corresponding to this instruction information #1 of carrying (in other words, flag) put 1, identifying the target mapped mode selected by the network equipment is the first mapped mode, and, the network equipment can pass through to be sent in the message of terminal unit #1 the bit corresponding to this instruction information #1 of carrying (in other words, flag) set to 0, identifying the target mapped mode selected by the network equipment is the second mapped mode.

It addition, in embodiments of the present invention, this first instruction information can be carried on the network equipment and be sent to the control information of terminal unit, for instance, in Downlink Control Information (DCI, DownlinkControlInformation).

Further, in embodiments of the present invention, terminal unit #1 can also be carried out scheduling of resource by the network equipment, to notify that terminal unit #1 carries out the running time-frequency resource that resource mapping process uses.

Terminal unit #1 is after receiving this instruction information #1, it is possible to from above-mentioned first mapped mode and the second mapped mode, selects the mapped mode corresponding with this instruction information #1, as upstream data #1 carries out the target mapped mode that resource mapping uses.

Thereafter, terminal unit #1 can according to the scheduling of resource of the network equipment, and based target mapped mode carries out resource mapping process (including processing) for the resource mapping process of data signal and the resource mapping for demodulated reference signal.

Such as, Fig. 6 illustrates as N=6, and the method for terminal unit #1 transmission upstream data according to embodiments of the present invention carries out resource mapping process and a schematic diagram of the demodulated reference signal that obtains and data signal.As shown in Figure 6, under normal CP, at time slot 0 and time slot 1, corresponding 12 subcarriers of the demodulated reference signal of terminal unit #1, that is, in Fig. 6, subcarrier #0～subcarrier #11, and, corresponding 6 subcarriers of data signal, i.e. in Fig. 6, subcarrier #0～subcarrier #5.As shown in Figure 6, data signal correspondence subcarrier is a part for demodulated reference signal correspondence subcarrier, and in other words, data signal correspondence subcarrier belongs to demodulated reference signal correspondence subcarrier.

Needing to be sent to part or all of total data signal of the network equipment it should be noted that the data signal shown in Fig. 6 can be terminal unit #1, the present invention is also not particularly limited.Such as, when upstream data #1 needs 3 RB#3 carryings, it is necessary to distribute 24 subcarriers to carry three data signals and two demodulated reference signals for this terminal unit #1.And, 12 subcarriers that the corresponding RB#2 corresponding to first demodulated reference signal of 12 subcarriers that two RB#3 corresponding to the first two data signal take takies, front 6 subcarriers in 12 subcarriers that the corresponding RB#2 corresponding to second demodulated reference signal of 6 subcarriers that the RB#3 corresponding to last data signal takies takies.

Alternatively, if this target mapped mode is this first mapped mode, and position that this W subcarrier is in carrying first time slot of the first subframe of this first data signal and the second time slot is identical, then at this first time slot, this T subcarrier includes the subcarrier being positioned at primary importance in W subcarrier, at this second time slot, this T subcarrier includes the subcarrier being positioned at the second position in this W subcarrier, and this primary importance is different with this second position.

Namely, in embodiments of the present invention, in two time slots of a subframe, if W son of carrying demodulated reference signal is identical in the position of ripple, the position of T subcarrier of carry data signals in two time slots then can be made different, i.e., it is possible to adopt frequency-hopping mode to carry out processing for the resource mapping of data signal.Specifically, if terminal unit #1 adopts the first mapped mode to carry out resource mapping, and the sub-carrier number T shared by the data signal ultimately generated is (such as, 6) the sub-carrier number W (such as, 12) shared by < demodulated reference signal, then such as, when N=6, this upstream data #1 has only taken up a RB#3, and in this situation, terminal unit #1 only uses a RB#2 to transmit demodulated reference signal.Fig. 7 illustrates as N=6, and the method for terminal unit #1 transmission upstream data according to embodiments of the present invention carries out resource mapping process and another schematic diagram of the demodulated reference signal that obtains and data signal.As it is shown in fig. 7, at time slot 0 (example of the first time slot of the first subframe), corresponding 12 subcarriers of the demodulated reference signal of terminal unit #1, namely, in Fig. 7, subcarrier #0～subcarrier #11, and, corresponding 6 subcarriers of data signal, that is, in Fig. 7, subcarrier #0～subcarrier #5.At time slot 1 (example of the second time slot of described first subframe), corresponding 12 subcarriers of the demodulated reference signal of terminal unit #1, i.e. in Fig. 7, subcarrier #0～subcarrier #11, and, corresponding 6 subcarriers of data signal, that is, in Fig. 7, subcarrier #6～subcarrier #11.As it is shown in fig. 7, data signal correspondence subcarrier is a part for demodulated reference signal correspondence subcarrier, in other words, data signal correspondence subcarrier belongs to demodulated reference signal correspondence subcarrier.

In embodiments of the present invention, owing to data signal is at the corresponding different subcarrier of different time-gap, diversity gain can be utilized, such as, when the channel quality corresponding to subcarrier #0～subcarrier #5 is poor and channel quality corresponding to subcarrier #6～subcarrier #11 is higher, it can be avoided that data signal is all the time at second-rate transmission such that it is able to improve communication quality.

Should be understood that frequency-hopping mode listed above is only the example that the resource for data signal maps, the present invention is not limited to this, for instance, in embodiments of the present invention, this primary importance and this second position can also be identical.

Alternatively, if this target mapped mode is this first mapped mode, then this W subcarrier position in carrying first time slot of the second subframe of this first demodulated reference signal and the second time slot is different.

Specifically, in embodiments of the present invention, can also carry out processing for the resource mapping of demodulated reference signal with frequency-hopping mode, that is, at time slot 0 (example of the first time slot of the second subframe), W subcarrier of this first demodulated reference signal is carried for such as, subcarrier #0～subcarrier #11, at time slot 1 (example of the second time slot of the second subframe), W the subcarrier carrying this first demodulated reference signal is such as, subcarrier #12～subcarrier #23.

In embodiments of the present invention, owing to demodulated reference signal is at the corresponding different subcarrier of different time-gap, diversity gain can be utilized, such as, when the channel quality corresponding to subcarrier #0～subcarrier #11 is poor and channel quality corresponding to subcarrier #12～subcarrier #23 is higher, it can be avoided that demodulated reference signal is all the time at second-rate transmission such that it is able to improve communication quality.

Alternatively, if this target mapped mode is this first mapped mode, then T < W, and this first data signal is that this first terminal equipment is based on the first power control factor α₁The data signal obtained after carrying out power amplification process, this first demodulated reference signal is that this first terminal equipment is based on the second power control factor α₂The demodulated reference signal obtained after carrying out power amplification process, wherein, α₂=T/W α₁。

Specifically, when adopting the first mapped mode to map, in order to the data signal after making mapping process meets uplink transmission power requirement, it is necessary to the uplink transmission power making data signal is P_PUSCH,c, and, the uplink transmission power making demodulated reference signal is P_PUSCH,c, wherein P_PUSCH,cAnd the relating to parameters such as the path loss between terminal unit #1 and the network equipment.

In this situation, terminal unit #1 can be that above-mentioned data signal is multiplied by power factor β_PUSCH(that is, the first power control factor α₁An example), to meet the requirement of user uplink transmitting power so that the uplink transmission power of data signal is P_PUSCH,c。

Similarly, for instance, work as N=6, and when only using 1 RB#3 to transmit data signal, terminal unit #1 can be that above-mentioned pilot tone is multiplied by power factor 6/12 × β_PUSCH=β_PUSCH/ 2 (that is, the second power control factor α₂)。

Work as N=6, and when using x RB#3 to transmit data, terminal unit #1 can be that above-mentioned pilot tone is multiplied by power factor

Alternatively, the method also includes:

This network equipment sends to this first terminal equipment and is used for indicating this first power control factor α₁Or this second power control factor α₂Information.

Specifically, in embodiments of the present invention, the network equipment can also determine above-mentioned first power control factor α according to parameters such as the path losses between terminal unit #1 and the network equipment₁And by this first power control factor α of instruction₁Information (following, for the ease of understanding and distinguishing, to be denoted as instruction information #2) be issued to terminal unit #1.Thus, terminal unit #1 can know this first power control factor α₁And according to α₂=T/W α₁, calculate and obtain the second power control factor α₂。

Or, this network equipment also will be used for determining that the isoparametric signal of path loss is issued to terminal unit #1, thus, terminal unit #1 can determine the parameters such as the path loss between the terminal unit #1 network equipment according to above-mentioned 5th instruction information, and then determines above-mentioned first power control factor α₁, and, thus, terminal unit #1 can according to α₂=T/W α₁, calculate and obtain the second power control factor α₂。

Again or, this instruction information #2 can be used for instruction the second power control factor α₂.Thus terminal unit #1 can according to α₂=T/W α₁, calculate and obtain the first power control factor α₁。

It should be noted that in embodiments of the present invention, this instruction information #2 and above-mentioned instruction information #1 can be carried in same message, i.e. the network equipment can pass through once to send process and be sent to terminal unit #1 with instruction information #1 by this instruction information #2 simultaneously.Further, in embodiments of the present invention, other information of interval therebetween that can be continuous print can also be this instruction information #2 and instruction information #1 position in the message, the present invention is also not particularly limited.

Or, this instruction information #2 and above-mentioned instruction information #1 can also be carried in different messages, that is, this instruction information #2 can be sent to terminal unit #1 with instruction information #1 respectively by the network equipment by twice transmission process, and concrete transmission process and transmission times are not particularly limited to by the present invention.
