Fig. 5 demodulates pilot frequency design schematic diagram one for the candidate of the inventive method embodiment two.Fig. 5 A demodulate pilot frequency design schematic diagram two for the candidate of the inventive method embodiment two.Fig. 6 demodulates pilot frequency design schematic diagram three for the candidate of the inventive method embodiment two.Fig. 7 demodulates pilot frequency design schematic diagram four for the candidate of the inventive method embodiment two.Fig. 8 demodulates pilot frequency design schematic diagram five for the candidate of the inventive method embodiment two.Fig. 9 demodulates pilot frequency design schematic diagram six for the candidate of the inventive method embodiment two.Figure 10 demodulates pilot frequency design schematic diagram seven for the candidate of the inventive method embodiment two.Figure 11 demodulates pilot frequency design schematic diagram eight for the candidate of the inventive method embodiment two.Figure 12 demodulates pilot frequency design schematic diagram nine for the candidate of the inventive method embodiment two.On the basis of embodiment of the method shown in Fig. 1, in the present embodiment, in at least one candidate demodulation pilot frequency design, the time interval that at least one described non-zero power demodulated pilot signal takes is different with the time interval that at least one zero energy demodulated pilot signal takes, and the frequency bandwidth of non-zero power demodulated pilot signal occupancy and the frequency bandwidth of zero energy demodulated pilot signal occupancy are also different.

Or

In at least one candidate demodulation pilot frequency design, the time interval that all non-zero power demodulated pilot signals take is different with the time interval that all zero energy demodulated pilot signals take, and the frequency bandwidth of all non-zero power demodulated pilot signal occupancy and the frequency bandwidth of all zero energy demodulated pilot signals occupancy are also different.

Specifically, in candidate's demodulation pilot frequency design as shown in Figure 5, the RE that non-zero power DMRS takes be the 2nd, 7,12 subcarriers（Counted from the bottom up in Fig. 5) on the 6th, 7 OFDM (count from left to right）The RE that RE (grey RE) on the position of symbol, zero energy DMRS take is the 13 on the 1st, 6,11 subcarriers, the RE (grey grid RE) on the position of 14 OFDM symbols.The time interval that all non-zero power demodulated pilot signals take is the time span of first time slot, the time interval that all zero energy demodulated pilot signals take is the time span of second time slot, therefore the time interval that all non-zero power demodulated pilot signals take is different with the time interval that all zero energy demodulated pilot signals take, and the frequency bandwidth that all non-zero power demodulated pilot signals take is the 2nd, 7,12 subcarriers, and all zero energy demodulated pilot signals are accounted for Frequency bandwidth is the 1st, 6, the width of the frequency of 11 subcarriers, therefore the frequency bandwidth that the frequency bandwidth that takes of all non-zero power demodulated pilot signals and all zero energy demodulated pilot signals take is also different.

DMRS multiplex mode can be in the following way：Using the configuration mode in Fig. 5, Fig. 5 A, there can be 4 users to carry out MU MIMO multiplexings respectively, that is, have 8 users and be multiplexed, UE1, UE2, UE3, UE4, UE5, UE6, UE7, UE8.By UE1, UE2, UE5, UE6 points use configuration mode as shown in Figure 5, i.e. UE1 for one group, UE2, UE5, and UE6 sends demodulated pilot signal using the RE on the 6th on 2,7,12 subcarriers, the position of 7 OFDM symbols；UE3, UE4, UE7, UE8 point are for one group using configuration mode as shown in Figure 5A, i.e. UE3, UE4, UE7, UE8 sends demodulated pilot signal using the RE on the 13rd on 1,6,11 subcarriers, the position of 14 OFDM symbols；UE1 correspondence orthogonal intersections（1,1), scrambler is produced according to nscidO；UE2 correspondence orthogonal intersections（1, -1), same scrambler is produced according to nscidO；Therefore UE1 and UE2 is completely orthogonal.UE5 correspondence orthogonal intersections (1,1), scrambler is produced according to nscidl；UE6 correspondence orthogonal intersections（1, -1), same scrambler is produced according to nscidl；Therefore UE5 and UE6 is completely orthogonal.And UE1 is identical from the orthogonal intersection that although UE5 uses but scrambler is different, interference is not produced yet；UE1 and UE5 are corresponding（1,1) spread representation is two RE uses of the 6th and the 7th OFDM symbol on the subcarrier where each pilot tone（1,1) spread, UE2 and UE6's（1, -1) what is represented is that two RE of the 6th and the 7th OFDM symbol on the subcarrier where each pilot tone are used（1, -1) spread.UE3 correspondence orthogonal intersections（1,1), scrambler is produced according to nscidO, UE4 correspondence orthogonal intersections（1, -1), scrambler is produced according to nscidO；Therefore UE3 and UE4 is completely orthogonal.UE7 correspondence orthogonal intersections（1,1), scrambler is produced according to nscidl, UE8 correspondence orthogonal intersections（1, -1), scrambler is produced according to nscidl；Therefore UE7 and UE8 is completely orthogonal；UE3 and UE7 are corresponding（1,1) spread representation is two RE uses of the 13rd and the 14th OFDM symbol on the subcarrier where each pilot tone（1,1) spread, UE4 and UE8 are corresponding（1, -1) what is represented is that two RE of the 13rd and the 14th OFDM symbol on the subcarrier where each pilot tone are spread using (1, -1).Wherein, UE1, UE2, UE5 are identical with the RE positions that UE8 zero energy demodulated pilot signal takes with the RE that UE6 non-zero power demodulated pilot signal takes with UE3, UE4, UE7, therefore UE3, UE4, UE7 and UE8 will not produce interference to UE1, UE2, UE5 and UE6 pilot tone；UE1, UE2, UE5 are identical with the RE positions that UE8 non-zero power demodulated pilot signal takes with the RE that UE6 zero energy demodulated pilot signal takes with UE3, UE4, UE7, therefore UE1, UE2, UE5 and UE6 will not produce interference to UE3, UE4, UE7 and UE8 pilot tone.

There can also be user's multiplex mode of other numbers, similar with embodiment one, here is omitted. Alternatively, at least one candidate demodulation pilot frequency design, the time interval that all non-zero power demodulated pilot signals take is different with the time interval that all zero energy demodulated pilot signals take.

Specifically, above-mentioned situation can be using candidate's demodulation pilot frequency design as shown in Figure 3,4, as shown in Figure 3, the time interval that all non-zero power demodulated pilot signals take is the time span of first time slot, the time interval that all zero energy demodulated pilot signals take is the time span of second time slot, therefore the time interval that all non-zero power demodulated pilot signals take is different with the time interval that all zero energy demodulated pilot signals take, and here is omitted.

Alternatively, at least one candidate demodulation pilot frequency design, the frequency bandwidth that all non-zero power demodulated pilot signals take is different with the frequency bandwidth that all zero energy demodulated pilot signals take.

Specifically, in candidate's demodulation pilot frequency design as shown in Figure 6, the RE that non-zero power DMRS takes is the 6 on the 12nd subcarrier, the RE (grey RE) on the position of 7 OFDM symbols, and the on the 12nd subcarrier the 13rd, RE (grey RE) on the position of 14 OFDM symbols；The RE that zero energy DMRS takes is the 6 on the 2nd, 7 subcarriers, the RE (grey grid RE) on the position of 7 OFDM symbols, and the on the 2nd, 7 subcarriers the 13rd, RE (grey grid RE) on the position of 14 OFDM symbols.Contrast in physical resource unit RE and Fig. 6 that the RE and zero energy DMRS that non-zero power DMRS in candidate's demodulation pilot frequency design as shown in Figure 7 takes take, that is the RE that the non-zero power DMRS in the RE corresponding diagrams 6 that the zero energy DMRS in the RE that the zero energy DMRS in the RE corresponding diagrams 6 that the non-zero power DMRS in Fig. 7 takes takes, Fig. 7 takes takes.The frequency bandwidth that all non-zero power demodulated pilot signals take in above-mentioned pattern is different with the frequency bandwidth that all zero energy demodulated pilot signals take, and frequency bandwidth is, for example, the width of the frequency of subcarrier herein.Such candidate's demodulation pilot frequency design can increase the sampling of time, improve the performance of channel estimation.
