No longer it is the demodulation reference from 11 kinds of pairing users in terms of existing technologies in first embodiment of the invention Selected in signal transmission parameters group for user equipment, but the demodulated reference signal of user is matched from N (being less than or equal to 10) kind Selected in set of transmission parameters, therefore reduce the complexity of terminal blind check.

In the specific embodiment of the invention, in order to further reduce the demodulated reference signal transmissions ginseng of selected pairing user The notification overhead of array, the N can be less than or equal to 8, the length of the parameter transmissions field is less than or equal to 3 bits.

When the N is less than or equal to 8, for notifying the demodulated reference signal transmissions parameter group of selected pairing user Parameter transmissions field only need 3 bits, or even less, reduce the demodulated reference signal transmissions parameter group of transmission pairing user Expense.

It is as follows to this further description.

In first embodiment of the invention, the demodulated reference signal transmissions parameter group of the pairing user is believed including demodulation reference Number port numbers, demodulated reference signal sequence sequence number and orthogonal mask sequence length.

When the demodulated reference signal transmissions parameter group for matching user includes port parameter and scrambler sequence parameter, it is combined Situation is as shown in table 1 below.

Value Match the demodulated reference signal transmissions parameter group of user 0 Layer:1, port:7, scrambler sequence:NSCID=0, OCC=2 1 Layer:1, port:7, scrambler sequence:NSCID=1, OCC=2 2 Layer:1, port:8, scrambler sequence:NSCID=0, OCC=2 3 Layer:1, port:8, scrambler sequence:NSCID=1, OCC=2 4 Layer:1, port:7, scrambler sequence:NSCID=0, OCC=4 5 Layer:1, port:7, scrambler sequence:NSCID=1, OCC=4 6 Layer:1, port:8, scrambler sequence:NSCID=0, OCC=4 7 Layer:1, port:8, scrambler sequence:NSCID=1, OCC=4 8 Layer:1, port:11, scrambler sequence:NSCID=0, OCC=4 9 Layer:1, port:11, scrambler sequence:NSCID=1, OCC=4 10 Layer:1, port:13, scrambler sequence:NSCID=0, OCC=4 11 Layer:1, port:13, scrambler sequence:NSCID=1, OCC=4

Table 1:The optional configured transmission table of reference signal

As shown in Table 1, therefrom it can be found that impose a condition for port it is identical when, match the demodulated reference signal of user The alternative of set of transmission parameters is as follows:

When port is 7, alternative is 3;

When port is 8, alternative is 3;

When port is 11, alternative is 1;

When port is 13, alternative is 1.

That is, after setting port identical screening conditions, the length of parameter transmissions field is set as 2 bits i.e. Can, less than 4 bits of prior art.

The parameter field may be used to indicate that the situation for not matching user, collectively form 4 kinds of selections.

As shown in Table 1, therefrom it can be found that imposing a condition as the demodulated reference signal sequence sequence in scrambler sequence parameter When number (nSCID) is identical, the alternative for matching the demodulated reference signal transmissions parameter group of user is as follows:

During demodulated reference signal sequence serial number 0, alternative is 5;

During demodulated reference signal sequence serial number 1, alternative is 5;

That is, after setting demodulated reference signal sequence sequence number identical screening conditions, the length of parameter transmissions field Degree is set as 3 bits, less than 4 bits of prior art.

As shown in Table 1, therefrom it can be found that imposing a condition as the orthogonal mask sequence length phase in scrambler sequence parameter Meanwhile the alternative for matching the demodulated reference signal transmissions parameter group of user is as follows:

When orthogonal mask sequence (OCC) length is 2, alternative is 3;

When orthogonal mask sequence (OCC) length is 4, alternative is 7;

That is, after setting orthogonal mask sequence length identical screening conditions, the length of parameter transmissions field is set It is set to 3 bits, less than 4 bits of prior art.

As previously described, certainly, the parameter field may be used to indicate that the situation for not matching user.

Therefore, in the first embodiment of the invention, for convenience of selection, can set:The demodulation ginseng of N number of pairing user Examine the demodulated reference signal transmissions parameter group of each pairing user in signal transmission parameters group and the demodulation ginseng of service user Examine in signal parameter sets, in demodulated reference signal port numbers, demodulated reference signal sequence sequence number and orthogonal mask sequence length One or two is identical, you can reduces the length of parameter transmissions field to 3 bits, or even only needs 1 bit.

Certainly, when in demodulated reference signal port numbers and demodulation reference signal sequence sequence number and orthogonal mask sequence length When more parameters is identical, the scale of the demodulated reference signal transmissions parameter group of the pairing user filtered out can be further reduced, Reduce the length of parameter transmissions field.

After such as setting demodulated reference signal sequence sequence number and orthogonal mask sequence length identical screening conditions, pairing is used The alternative of the demodulated reference signal transmissions parameter group at family is then only left:

Demodulated reference signal sequence serial number 0, when orthogonal mask sequence length is 2, alternative is 1;

Demodulated reference signal sequence serial number 0, when orthogonal mask sequence length is 4, alternative is 3;

Demodulated reference signal sequence serial number 1, when orthogonal mask sequence length is 2, alternative is 1;

Demodulated reference signal sequence serial number 1, when orthogonal mask sequence length is 4, alternative is 3.

However, it is to be understood that it can also arbitrarily select N number of pairing user's from 12 kinds of reference signal transmission plans Demodulated reference signal transmissions parameter group, is not especially limited herein.

Certainly, which scheme is at least selected to form above-mentioned N kinds pairing from 12 kinds of above-mentioned reference signal transmission plans The demodulated reference signal transmissions parameter group of user can not retouched in detail herein as needed and/or actual conditions are selected State.

In the specific embodiment of the invention, when 2N(N is the bit number of parameter transmissions field) is more than optional demodulation reference and believed During the quantity of number set of transmission parameters, the parameter field may be used to indicate that the situation for not matching user.Follow-up embodiment is same Sample is applicable, and is not repeated to describe later.
