In certain embodiments, the network equipment 150 can be included in 310 create the parameter of higher be to indicate IFDMA It is no to be activated, for example, creating one or more parameters in wireless heterogeneous networks (RRC) layer to indicate whether IFDMA is activated.When When the parameter instruction IFDMA of higher is activated, it can be used to transmit to distribute subcarrier for terminal device using such as table 1 below Line link DMRS.

Table 1

When the parameter instruction IFDMA of higher is not enabled, existing form (for example, Release 10) can be used. In table 1, the comb1 and comb2 of IFDMA combs (comb) can be used to indicate that odd subcarriers and even subcarriers, otherwise also So.As an example, comb1 represents odd subcarriers, comb2 represents even subcarriers.Exemplary distribution method will below Middle combination table 2 and Fig. 4 A and Fig. 4 B is described in detail.It should be appreciated that the mode of a variety of distribution IFDMA subcarriers be present, because This, those skilled in the art can carry out other changes and improvements under the teaching of the method for salary distribution described by the disclosure.

In this way, while enhanced uplink DMRS is realized, conveniently existing system can be changed Become, do not change traditional DCI configurations especially.

In certain embodiments, it can also include what whether the generation instruction of the network equipment 150 IFDMA be activated in 310 DCI.In this way, while it is desirable to DCI is changed, but due to being that lower level is adjusted, is realizing that enhancing is up While link DMRS, more can flexibly it be configured in response to the change of system, so that the distribution of subcarrier is more Optimization.

In certain embodiments, it is activated in response to IFDMA, the network equipment 150 can generate DCI to indicate to be used for first Terminal device 110 performs the subcarrier of up-link DMRS transmission.Specifically, indicate that the scheme of distributed subcarrier can divide For two classes：The first kind, DCI position is not increased, i.e. without using the extension bits in cyclic shift domain, but need to follow using current Ring displacement domain sub-carrier is redistributed；Second class, increase DCI position, i.e. using the extension bits in cyclic shift domain, Other positions in DCI can also be utilized, indicates whether IFDMA is activated using the position, is allocated with sub-carrier.

Hereafter first first kind subcarrier distribution scheme is discussed, i.e. do not increase DCI position, do not change CS/OCC and match somebody with somebody Put, only increase implicit IFDMA combs (comb) instruction under CS domains.Table 2 below shows the specific distribution of subcarrier.

Table 2

In table 2,The occurrence of cyclic shift (CS) is represented, four train values represent four layers respectively, in OCC columns Four row also represent this four layers.It should be appreciated that the number of plies described herein is variable and expansible.DCI is generated to distribute IFDMA subcarriers specifically include：Create CS domains in DCI, the information in CS domains is used to specify first terminal equipment 110 to be allocated The subcarrier of serial number even number, or the first end are assigned to the subcarrier of serial number odd number and second terminal equipment 120 End equipment 110 is assigned to the subcarrier of serial number even number and second terminal equipment 120 is assigned to the son of serial number odd number Carrier wave, and for first terminal equipment 110 and the distribution identical of second terminal equipment 120 OCC, (visible each pair odd even is sub in table 2 Carrier wave is respectively provided with the 1st, 2 layer of identical OCC).As described above, CS/OCC configurations do not change.And form last row are shown The instruction of IFDMA combs, i.e. the instruction of odd number or even subcarriers when duplication factor is 2.Below in reference to Fig. 4 A and Fig. 4 B To describe the method for distributing IFDMA subcarriers.

Fig. 4 A and Fig. 4 B show according to some embodiments of the disclosure without using the extension bits in cyclic shift domain come Distribute the schematic diagram of subcarrier.As an example, first, first and second layer of row for [1 1] of OCC is selected in table 2, so as at this The respective value of first row in CS occurrences is found in four rows, i.e. 0,4,2,9.Afterwards, as shown in Figure 4 A, 9 relative to 0,4,2 tools There is the spacing distance (separation) of maximum, can be odd subcarriers by 9 selections therefore.And due to 2 and 4 to 9 interval Apart from spacing distances identical and more than 0 to 9, therefore optionally one of them is even subcarriers, selects 2 to be carried as even number here Ripple.Remaining 0 and 4 elect no IFDMA as.Next first and second layer of row for [1-1] of OCC is selected in table 2, it is specific to find CS The respective value of first row in value, i.e. 6,3,8,10.Afterwards, as shown in Figure 4 B, 3 have maximum spacer relative to 6,8,10 From therefore, it is odd subcarriers that can be selected 3.Again because 8 is identical with 10 to 3 spacing distance and is more than 6 to 3 interval Distance, therefore optionally one of them is even subcarriers, selects 8 to be used as even subcarriers here.Remaining 6 and 10 elect nothing as IFDMA.Thus the distribution of IFDMA subcarriers is just completed.It should be appreciated that the mode of a variety of distribution IFDMA subcarriers be present, because This, those skilled in the art can carry out other changes and improvements under the teaching of the method for salary distribution described by the disclosure.

As another example, Fig. 4 C and Fig. 4 D are shown according to the improvement embodiment of the disclosure without using cyclic shift domain In extension bits distribute the schematic diagram of subcarrier.As depicted in figs. 4 c and 4d, in figure 2 and 3 position is exchanged, then such as Fig. 4 C Shown, 9 and 3 have maximum spacing distance, and as shown in Figure 4 D, 8 and 2 have maximum spacing distance.Therefore, thus embodiment The subcarrier distributed for the terminal device of pairing has more preferable correlation.Table 3 below shows the tool of improved subcarrier Body is distributed, it can be seen that the CS values of the 3rd row and the 5th row are exchanged in table 3.

Table 3

As another example, it is also an option that CS valuesIt is used for IFDMA in first layer for 0,6,3,9 four rows Subcarrier distributes, as shown in table 4 below.It can be seen that the difference of table 4 and table 2 is that four CS domains are selected for IFDMA and matched somebody with somebody Put.

Table 4

In addition, the DMRS that the length in arrowband Internet of Things (NB-loT) in R13 (Release 13) is 6 can also be carried out Subcarrier distributes.Because the cyclic shift as shown in table 1-4 has 12 different values, and the length in NB-loT is 6 DMRS only has 4 different cyclic shift values 0,1,2,4, this 4 values can be mapped as into 0,2,4,8.The specific method of salary distribution It can refer to Fig. 4 A and Fig. 4 B description.Specific IFDMA sub-carrier allocation results are as shown in table 5.In addition, those skilled in the art This table can also be changed, table 5 is improved for example, referring to the improved procedure of table 3.In addition, table 5 can respectively with table 1st, table 2, table 3 or table 4 merge, and detail repeats no more.

Table 5

The second class subcarrier distribution scheme will be discussed below, i.e. increase DCI position.It is, for example, possible to use circulation The extension bits in domain are shifted, other positions in DCI can also be utilized, indicate whether IFDMA is activated using the position, with antithetical phrase Carrier wave is allocated.Fig. 5 A and Fig. 5 B are shown according to some embodiments of the disclosure using the extension bits in cyclic shift domain To distribute the schematic diagram of subcarrier, the specific method of salary distribution can refer to the description as described in Fig. 4 A and Fig. 4 B.Following table 6 is with CS domains In an extension bits are added before original three is to be illustrated the specific distribution of subcarrier.The extension bits can be with table when being 0 Show that no IFDMA is used for DMRS, the extension bits can indicate that IFDMA is used for DMRS when being 1.In addition, table 6 can merge with table 5, Detail repeats no more.

Table 6

Due to there is 8 new entries to be used for IFDMA, it is allowed to which IFDMA duplication factor is 4 and has two OCC codes.One money 12 subcarriers during source is fast can be divided into 4 comb (comb) groups.If the duplication factor used is only the Hes of 2, comb 1 Comb 3 retracts to be retracted as even subcarriers for odd subcarriers, comb 2 and comb 4.In addition, those skilled in the art may be used also To be changed to this table, table 6 is improved for example, referring to the improved procedure of table 3.

Those skilled in the art should be noted that physical mixed automatic re-transmission indicating channel (PHICH) by exponent pairRepresent, whereinIt is PHICH group numbers, andIt is the orthogonal sequence index in group, is limited by following formula：

Wherein n_DMRSIt is mapped as that there is up-link DCI format 4 in newest Physical Downlink Control Channel (PDCCH) DMRS domains (referring to table 7, i.e. table 9.1.2-2 in standard) cyclic shift.

Table 7

Because in table 7 above, the cyclic shift in DMRS domains is changed to 4, in order to be continuing with existing table 7, therefore only N is obtained using latter three of cyclic shift domain_DMRS, extension bits is ignored, so as to avoid PHICH index conflicts.
