Fig. 3 is the flow chart of DMRS transmission methods embodiment two of the present invention, as shown in figure 3, the method for the present embodiment can be with Including：

Step 201, base station determine the DMRS patterns of DMRS antenna ports.

Step 202, base station send DMRS instruction messages to user equipment, and DMRS instruction messages are used to indicate DMRS antenna ends Mouthful DMRS patterns, DMRS patterns be the running time-frequency resource there are DMRS position and/or DMRS occupy RE in running time-frequency resource Position so that user equipment determines the DMRS patterns of DMRS antenna ports according to DMRS instruction messages, and according to DMRS antennas The DMRS patterns of port obtain DMRS.

Step 203, base station send DMRS according to DMRS patterns to user equipment.

In the present embodiment, base station needs to send DMRS to user equipment according to certain DMRS patterns, and therefore, base station is first The DMRS patterns of DMRS antenna ports are determined according to the application scenarios of Ying Ji, are then set according to identified DMRS patterns to user Preparation send DMRS, since base station can determine the DMRS patterns of DMRS antenna ports from multiple DMRS patterns candidate collections, So in order to which user equipment is enable to be accurately obtained the DMRS of base station transmission, so base station needs to scheme DMRS determined by base station Case informs that therefore, base station sends DMRS instruction messages to user equipment, and DMRS instruction messages are used to indicate DMRS to user equipment The DMRS patterns of antenna port, DMRS patterns be the running time-frequency resource there are DMRS position and/or DMRS occupy RE in time-frequency Position in resource, so that user equipment receives DMRS instruction messages, it may be determined that the DMRS patterns of DMRS antenna ports, together When also know base station be according to the DMRS patterns to user equipment send DMRS, i.e., DMRS and RE are provided according to DMRS patterns Source maps, and the RE that can determine to occupy there are DMRS and/or DMRS in which running time-frequency resource so as to user equipment is in running time-frequency resource In position, so as to the specific location of the RE occupied according to DMRS, from these RE obtain base station sends to user equipment DMRS.

DMRS patterns specified in LTE protocol are respectively configured to base station and user equipment in the prior art, in practical application In, the RE expenses of DMRS occupancy of transmission no matter are actually needed whether less than the DMRS in DMRS patterns specified in LTE protocol The RE expenses of occupancy, base station can only send DMRS according to DMRS patterns specified in LTE protocol, so that under the utilization rate of RE Drop.

DMRS transmission methods provided in an embodiment of the present invention first determine the DMRS patterns of DMRS port by base station, i.e., really Surely there are the position of running time-frequency resource of DMRS and/or positions of the RE in running time-frequency resource that occupies of DMRS, and by the DMRS patterns It is informed by DMRS instruction messages to user equipment, then sends DMRS to user equipment further according to DMRS patterns, so that User equipment obtains DMRS according to the DMRS patterns indicated in DMRS instruction messages, realizes when DMRS expenses are relatively low, base station DMRS is sent to user equipment according to the relatively low DMRS patterns of DMRS expenses, user equipment is according to the relatively low DMRS patterns of the expense Obtain DMRS, solve the problems of the prior art, and improve the utilization rate of RE so that can secured transmission of payload data RE Increase, improve data transmission rate.

On the basis of the embodiment of the present invention one or the embodiment of the present invention two, base station can send one to user equipment DMRS instruction messages, correspondingly, user equipment receive the DMRS instruction message that base station is sent, a DMRS instruction message It is used to indicate the DMRS patterns of at least one DMRS antenna ports.Specifically, the DMRS patterns of different DMRS antenna ports can With identical, then a DMRS pattern can be determined by a DMRS instruction message, and all DMRS antenna ports DMRS patterns are to pass through this DMRS pattern determined by DMRS instruction messages；The DMRS patterns of different DMRS antenna ports can With difference, for each antenna port, the correspondence between DMRS instruction messages and DMRS patterns can be pre-defined, from And pair between DMRS instruction messages and DMRS patterns can be corresponded to according to same DMRS instruction messages and different antennae port It should be related to, so that it is determined that the DMRS patterns of different antennae port.So as to reduce the signaling consumption of DMRS instruction messages.

Alternatively, base station sends at least two DMRS instruction messages to user equipment, correspondingly, user equipment receives base station hair At least two DMRS instruction messages sent, each DMRS instruction messages are used to indicate the DMRS patterns of a DMRS antenna port. Specifically, a DMRS instruction message can only indicate the pattern of a DMRS antenna port, different DMRS antenna ports DMRS patterns can be different, can also be identical, therefore can realize that, for different DMRS antenna ports, the RE that DMRS is occupied is opened Pin can be different, so as to adapt to requirement of the different DMRS antenna ports to DMRS density.

Above-mentioned DMRS instruction messages are used to indicate the DMRS patterns of DMRS antenna ports, including：Above-mentioned DMRS instructions disappear Cease the position of the density for being used to indicate DMRS, the interval degree of DMRS, the bitmap coded of DMRS and/or the running time-frequency resource there is no DMRS It puts, wherein, the density of DMRS, the interval degree of DMRS, the position of the bitmap coded of DMRS and/or the running time-frequency resource there is no DMRS For determining the DMRS patterns of DMRS antenna ports.And running time-frequency resource can include：RB to, RB groups, half of subframe, subframe, RB groups in subframe group or subframe group；Running time-frequency resource can be that pre-defined either base station is allocated to user equipment.

The density of DMRS can be the number for the RE that DMRS is occupied in running time-frequency resource, since density and the DMRS of DMRS scheme Case may have correspondence, the DMRS patterns of DMRS antenna ports can be determined by the density of DMRS, such as DMRS is in RB Can be 12 to the RE of upper occupancy (DMRS patterns can using as shown in Figure 1, the RE expenses that occupy of DMRS as 7%) or 4 (DMRS patterns Can using as shown in figure 4, DMRS occupy RE expenses for 2.4%) or 2 (DMRS patterns can with as shown in figure 5, DMRS occupancy RE 1.2%) or 0 expense is.

The interval degree of DMRS can be the space-number of the running time-frequency resource there are DMRS, if there are between the running time-frequency resource of DMRS Be n every number, then there are one running time-frequency resources there are DMRS during explanation is per n running time-frequency resource, wherein, the running time-frequency resource there are DMRS exists Position in n running time-frequency resource can be it is pre-defined can also be base station by signaling to user equipment；Due to The interval degree of DMRS may have correspondence with DMRS patterns, and DMRS antenna ports can be determined by the interval degree of DMRS DMRS patterns, such as DMRS can be 2 to the number of the RE of upper occupancy in a RB, and there are RB pairs of DMRS at intervals of 2, this When DMRS pilot frequency design can using as shown in fig. 6, at this time DMRS occupy RE expenses as 0.6%.

The bitmap coded of DMRS can be Y bit, wherein each bit and at least one RE that may be occupied by DMRS It is corresponding, if a bit is set to ' 1 ', then represent that the corresponding at least one RE of the bit is occupied by DMRS, if one Bit is set to ' 0 ', then represent that the corresponding at least one RE of the bit is not occupied by DMRS, such as Y is 12, wherein each Bit is corresponding with the RE that DMRS in Fig. 1 is occupied respectively, if a bit is set to ' 1 ', then represent the corresponding RE of the bit It is occupied by DMRS, if a bit is set to ' 0 ', then represent that the corresponding RE of the bit is not occupied by DMRS, then such as Y For 3, wherein each bit is corresponding with 4 RE for belonging to same sub-carrier that DMRS in Fig. 1 is occupied respectively, if a bit quilt It is set to ' 1 ', then represent that corresponding 4 RE of the bit are occupied by DMRS, if a bit is set to ' 0 ', then representing should Corresponding 4 RE of bit are not occupied by DMRS, since bitmap coded and the DMRS patterns of DMRS may have correspondence, are led to The DMRS patterns of DMRS antenna ports can be determined by crossing the bitmap coded of DMRS.

If DMRS instruction messages indicate the position of the running time-frequency resource there is no DMRS, it can correspondingly determine exist The running time-frequency resource of DMRS, the position since there is no the running time-frequency resource of DMRS may have correspondence with DMRS patterns, therefore It can determine the DMRS patterns of DMRS antenna ports.

Further, all RB for being scheduled to user equipment in M running time-frequency resource use identical precoding, and M is certainly So number.M can be 1, i.e., all RB for being scheduled to user equipment in each running time-frequency resource use identical precoding；Or Person, M can be the interval degree of DMRS, then are scheduled to there are all in the running time-frequency resource in the space-number of the running time-frequency resource of DMRS The RB of user equipment uses identical precoding, such as：As shown in fig. 6, there are DMRS RB pairs of space-number for 2, then RB0 with RB1 uses identical precoding, and RB2 and RB3 use identical precoding；Alternatively, M can be any one nature more than 2 Number, specifically, base station can also pass through height according to pre-defined system bandwidth to user device configuration precoding RB groups Layer signaling notify the value of M to user equipment, wherein, precoding RB groups include the RB in M running time-frequency resource, then precoding RB For all RB for being scheduled to user equipment in group using identical precoding, user equipment can be according to pre-defined system band The high-level signaling that the value or user equipment of the definite M of width is sent according to base station obtains the value of M.

The DMRS instruction messages to base station transmission or user equipment reception and the DMRS of DMRS instruction messages instruction scheme below Case is illustrated.
