Or

In at least one candidate demodulation pilot frequency design, the time interval of all non-zero power demodulation pilot signals occupancy It is different with the time interval that all zero energys demodulation pilot signal occupies, and all non-zero power demodulation pilot signals account for The frequency bandwidth that frequency bandwidth and all zero energys demodulation pilot signal occupy is also different.

Specifically, in candidate demodulation pilot frequency design as shown in Figure 5, the RE that non-zero power DMRS is occupied is the 2nd, 7,12 The the 6th, 7 OFDM on subcarrier (being counted from the bottom up in Fig. 5) (counts) RE (grey RE) on the position of symbol from left to right, and zero The RE that power DMRS is occupied is RE (the grey grids on the position of the 13rd, 14 OFDM symbol on the 1st, 6,11 subcarriers RE).The time interval that all non-zero power demodulation pilot signals occupy is the time span of first time slot, all zero powers Rate demodulates the time span that the time interval that pilot signal occupies is second time slot, therefore all non-zero power demodulation are led The time interval that frequency signal occupies and the time interval that all zero energys demodulation pilot signal occupies are different and all described non- Zero energy demodulate the frequency bandwidth that pilot signal occupies be the 2nd, 7,12 subcarriers, and all zero energys demodulate pilot signal The frequency bandwidth of occupancy is the 1st, 6, the width of the frequencies of 11 subcarriers, therefore all non-zero power demodulation pilot signals account for The frequency bandwidth that frequency bandwidth and all zero energys demodulation pilot signal occupy is also different.

The multiplex mode of DMRS may be used such as under type：Using the configuration mode in Fig. 5, Fig. 5 A, there can be 4 respectively User carries out MU MIMO multiplexings, that is, shares 8 users and be multiplexed, UE1, UE2, UE3, UE4, UE5, UE6, UE7, UE8.It will UE1, UE2, UE5, UE6 points use configuration mode as shown in Figure 5, i.e. UE1, UE2, UE5, UE6 all to use 2,7,12 for one group RE on the position of the 6th, 7 OFDM symbol on subcarrier sends demodulation pilot signal；UE3, UE4, UE7, UE8 points are one group Using configuration mode as shown in Figure 5A, i.e. UE3, UE4, UE7, UE8 uses the 13rd, 14 OFDM on 1,6,11 subcarriers RE on the position of symbol sends demodulation pilot signal；UE1 corresponds to orthogonal intersection (1,1), and scrambler is generated according to nscid0； UE2 corresponds to orthogonal intersection (1, -1), and same scrambler is generated according to nscid0；Therefore UE1 and UE2 is completely orthogonal.UE5 is corresponded to just Spreading code (1,1) is handed over, scrambler is generated according to nscid1；UE6 corresponds to orthogonal intersection (1, -1), and same scrambler is produced according to nscid1 It is raw；Therefore UE5 and UE6 is completely orthogonal.And UE1 is identical as although orthogonal intersection that UE5 is used but scrambler is different, also do not produce Raw interference；What corresponding (1,1) spreading codes of UE1 and UE5 indicated is the 6th and the 7th on the subcarrier where each pilot tone Two RE of OFDM symbol are spread using (1,1), and (1, -1) expression of UE2 and UE6 are in the son where each pilot tone Two RE of the 6th and the 7th OFDM symbol on carrier wave are spread using (1, -1).UE3 corresponds to orthogonal intersection (1,1), Scrambler is generated according to nscid0, and UE4 corresponds to orthogonal intersection (1, -1), and scrambler is generated according to nscid0；Therefore UE3 and UE4 is complete It is complete orthogonal.UE7 corresponds to orthogonal intersection (1,1), and scrambler is generated according to nscid1, and UE8 corresponds to orthogonal intersection (1, -1), scrambler It is generated according to nscid1；Therefore UE7 and UE8 is completely orthogonal；What corresponding (1,1) spreading codes of UE3 and UE7 indicated is led each Two RE of the 13rd and the 14th OFDM symbol on subcarrier where frequency are spread using (1,1), and UE4 and UE8 are corresponded to (1, -1) indicate is that two RE of the 13rd and the 14th OFDM symbol on the subcarrier where each pilot tone are used (1, -1) is spread.Wherein, UE1, UE2, UE5 and UE6 non-zero power demodulation pilot signal occupy RE and UE3, UE4, UE7 and UE8 zero energy demodulation pilot signal occupy the positions RE it is identical, therefore UE3, UE4, UE7 and UE8 will not to UE1, The pilot tone of UE2, UE5 and UE6 generate interference；The RE and UE3 of the zero energy demodulation pilot signal occupancy of UE1, UE2, UE5 and UE6, The positions RE that the non-zero power demodulation pilot signal of UE4, UE7 and UE8 occupy are identical, therefore UE1, UE2, UE5 and UE6 will not be right The pilot tone of UE3, UE4, UE7 and UE8 generate interference.

There can also be user's multiplex mode of other numbers, similar with embodiment one, details are not described herein again.

Optionally, at least one candidate demodulation pilot frequency design, the time of all non-zero power demodulation pilot signals occupancy It is different to be spaced the time interval occupied with all zero energys demodulation pilot signal.
