When the symbolic number that PDSCH DMRS includes is 1, the position of the additional DMRS in addition to first PDSCH DMRS It can be configured according to different scenes, such as table 3.

Table 3

When the symbolic number that PDSCH DMRS includes is 2, the position of the additional DMRS in addition to first PDSCH DMRS It can be configured according to different scenes, such as table 4.

Table 4

For map type B, when the symbolic number that PDSCH includes is 2 or 4 or 7, as part PDSCH and reserved control domain When resource contention, first PDSCH DMRS is located at first symbol after control domain.

DMRS in the embodiment of the present invention can be PUSCH DMRS, be also possible to PDSCHDMRS, right in turn below The configuration method explanation of PUSCH DMRS and PDSCH DMRS.

In the embodiment of the present invention, DMRS is PUSCH DMRS.

Referring to FIG. 3, the embodiment of the present invention provides the configuration method of PUSCH DMRS a kind of, set applied to network side Standby, the configuration method includes:

Step 31: the configuration information of DMRS location sets is sent by RRC signaling, wherein each DMRS location sets Comprising multiple positions DMRS subset, the corresponding DMRS parameter group of each position DMRS subset, in different DMRS parameter groups At least one is different for following DMRS parameter: symbolic number that DMRS includes, PUSCH map type, additional DMRS sum, Whether the symbolic number and PUSCH that PUSCH includes use frequency-hopping transmissions.

In the embodiment of the present invention, the configuration information for the DMRS location sets that network side equipment is sent can be the position DMRS collection The position DMRS subset itself in conjunction is also possible to represent the identification information of the position the DMRS subset in DMRS location sets, should In the case of kind, the mark of the predefined position the DMRS subset of agreement and the position DMRS subset is needed, terminal is receiving DMRS When setting the mark of subset, the corresponding position DMRS subset can be found out from predefined DMRS location sets.

It illustrates below and the concept of the position DMRS subset is illustrated.Table 1 is please referred to, in each grid in table 1 The position DMRS is known as the position a DMRS subset, for example, the sum of map type A, additional DMRS are that 1, PUSCH includes Symbolic number be 9 when, the corresponding position DMRS subset be l₀,7.It include at least in the embodiment of the present invention, in the subset of the position DMRS One position DMRS.

The corresponding column position the DMRS subset of the sum of same additional DMRS forms a DMRS location sets.Citing comes It says, the map type in table 1 is B, when the sum of additional DMRS is 3, the corresponding column position DMRS subset (0,3,6,9), (0, 3,6,9), (0,3,6,9), (0,3,6,9) form a DMRS location sets.That is, DMRS location sets are for one For the sum of additional DMRS, the corresponding DMRS location sets of the sum of an additional DMRS.

It illustrates below and the concept of DMRS parameter group is illustrated.DMRS parameter group includes DMRS parameter, DMRS parameter packet Include: whether the symbolic number and PUSCH that symbolic number that DMRS includes, PUSCH map type, the sum of additional DMRS, PUSCH include Using frequency-hopping transmissions.Table 1 is please referred to, the symbolic number that DMRS includes is 1, and the sum of map type A, additional DMRS are 2, The symbolic number that PUSCH includes is 14, these one DMRS parameter groups of composition, in the corresponding position the DMRS subset of the DMRS parameter group The number of the position DMRS be respectively l₀,7,11。

In the embodiment of the present invention, every DMRS parameter group corresponds to the position a DMRS subset, and different DMRS parameter groups are corresponding The position DMRS subset may be the same or different.In different DMRS parameter groups, at least one DMRS parameter is different.

Since network side equipment sends DMRS location sets to terminal by RRC signaling, terminal is receiving DCI instruction When DMRS configures relevant information, it can be selected related to DMRS configuration from the received multiple positions DMRS of network side The corresponding position the DMRS subset of information, to solve in the prior art, the sum and DCI of the additional DMRS of RRC signaling configuration refers to The DMRS configuration unmatched problem of relevant information shown, improves DMRS demodulation performance, and then improve message transmission rate.
