Below in conjunction with Figure of description, embodiments of the present invention is further illustrated, but the present invention is not limited to the following examples.

Embodiment mono-:

As shown in Figure 1, in the embodiment of the present invention one, the signal detecting method of PUCCH comprises the following steps:

Step 101: according to the signal on the PUCCH frequency pilot sign receiving, determine noise equivalent power value and the equivalent signal performance number of PUCCH channel.

Step 102: in the time that the ratio of the equivalent signal performance number of determining and noise equivalent power value is not less than predetermined threshold value, determines and PUCCH signal detected.

Wherein, step 101 can realize by following steps:

Step 1: for a reception antenna, according to the burst on the each PUCCH frequency pilot sign receiving on this reception antenna and pilot tone basic sequence corresponding to each transmit port, determine the pilot tone channel estimation sequence that frequency pilot sign and transmit port are corresponding.

Step 2: by each pilot tone channel estimation sequence of determining for every antenna, convert time domain pilot channel estimation sequence to.

Step 3: according to each time domain pilot channel estimation sequence, determine noise equivalent power value and the equivalent signal performance number of PUCCH channel.

Particularly, the specific implementation of step 1 can be:

Carry out respectively for every reception antenna: by the pilot tone basic sequence conjugate multiplication corresponding with each transmit port respectively of the burst on the each PUCCH frequency pilot sign receiving on this reception antenna, obtain each frequency pilot sign and pilot tone channel estimation sequence corresponding to each transmit port that this reception antenna is determined.

Wherein, the burst on frequency pilot sign and pilot tone basic sequence conjugate multiplication are referred to, by the element in the burst on frequency pilot sign and element conjugate multiplication corresponding in pilot tone basic sequence.For example, by first element conjugate multiplication in first element in the burst on frequency pilot sign and pilot tone basic sequence, the value obtaining is as the value of first element in pilot tone channel estimation sequence.

It should be noted that, the transmit port in embodiment of the present invention scheme refers to that transmitting terminal (for example UE, UE:User Equipment, subscriber equipment) sends the transmit port of PUCCH signal, and each transmit port can have corresponding pilot tone basic sequence.Wherein, every reception antenna of receiving terminal (for example base station) can receive respectively the PUCCH signal that each transmit port sends, the signal after the PUCCH signal stack that but the PUCCH signal that receiving terminal receives is multiple transmit ports to be sent, therefore, receiving terminal need to detect the PUCCH signal receiving according to pilot tone basic sequence corresponding to each transmit port, obtains the PUCCH signal that each port sends.Wherein, the pilot tone basic sequence that each transmit port is corresponding can be generated according to the parameter setting in advance by base station, also can indicate UE to generate and send to base station according to the parameter setting in advance by base station.

In specific implementation process, receiving terminal is that the data of receive subframe are processed after receiving PUCCH signal by reception antenna, wherein, a subframe comprises two time slots, for standard cyclic prefix (Normal CP, Normal Cyclic Prefix), a time slot comprises 7 OFDM symbols.14 of two time slots OFDM symbols are numbered respectively, obtain the call number 0～13 of 14 OFDM symbols, wherein, it is 0～6 OFDM symbol that first time slot (Slot1) comprises call number, and it is 7～13 OFDM symbol that second time slot (Slot2) comprises call number.

For an OFDM symbol, it can be frequency pilot sign, can be also data symbol.Wherein, frequency pilot sign refers to the OFDM symbol for transmission of reference signals in a subframe; Data symbol refers to the OFDM symbol except frequency pilot sign in a subframe.In a subframe, the call number of supposing frequency pilot sign is 1,5,8 and 12, and the call number of data symbol is 0,2,3,4,6,7,9,10,11 and 13.Wherein, the call number of the 1st frequency pilot sign that time slot comprises is 1 and 5, the call number of the 1st data symbol that time slot comprises is 0,2,3,4 and 6, the call number of the 2nd frequency pilot sign that time slot comprises is that the call number of 8 and 12, the 2 data symbols that time slot comprises is 7,9,10,11 and 13.A subframe comprises 4 frequency pilot signs and 10 data symbols, and each time slot comprises 2 frequency pilot signs and 5 data symbols.

Based on this, every reception antenna can receive respectively 4 frequency pilot signs and 10 data symbols at every turn, wherein, the 1st frequency pilot sign and the 2nd frequency pilot sign that reception antenna receives belong to the 1st time slot, the 1st data symbol～5th data symbol receiving belongs to the 1st time slot, the 3rd frequency pilot sign and the 4th frequency pilot sign that receive belong to the 2nd time slot, and the 6th data symbol～10th data symbol receiving belongs to the 2nd time slot.

It should be noted that the information that frequency-domain OFDM symbol comprises 12 subcarriers is transformed to the time domain OFDM symbol obtaining after time domain and comprises 12 sampled points information of (or being called footpath).12 subcarriers that the sequence of the embodiment of the present invention taking length as 12 comprises frequency pilot sign or data symbol or the information of sampled point describe, wherein, and the information that time domain sequences comprises 12 sampled points, the information that frequency domain sequence comprises 12 subcarriers.

Based on this, in step 1, the burst on each PUCCH frequency pilot sign, the pilot tone basic sequence that each transmit port is corresponding, and the length of each pilot tone channel estimation sequence is 12, the information that comprises 12 subcarriers.

Suppose to comprise 4 frequency pilot signs in a subframe that a reception antenna receives, and there are 2 transmit ports to send PUCCH signal, can determine 4*2=8 pilot tone channel estimation sequence for this reception antenna, wherein, 8 pilot tone channel estimation sequence that this reception antenna is determined are respectively: the 1st transmit port and the 1st the pilot tone channel estimation sequence that frequency pilot sign is corresponding that this reception antenna is determined, the 1st transmit port and the 2nd the pilot tone channel estimation sequence that frequency pilot sign is corresponding, the 1st transmit port and the 3rd the pilot tone channel estimation sequence that frequency pilot sign is corresponding, the 1st transmit port and the 4th the pilot tone channel estimation sequence that frequency pilot sign is corresponding, the 2nd transmit port and the 1st the pilot tone channel estimation sequence that frequency pilot sign is corresponding, the 2nd transmit port and the 2nd the pilot tone channel estimation sequence that frequency pilot sign is corresponding, the 2nd transmit port and the 3rd the pilot tone channel estimation sequence that frequency pilot sign is corresponding, and the 2nd transmit port and the 4th the pilot tone channel estimation sequence that frequency pilot sign is corresponding.

Suppose always to have 3 reception antennas, finally can obtain 3*4*2=24 pilot tone channel estimation sequence, wherein, every reception antenna obtains respectively 8 pilot tone channel estimation sequence, the information that comprises 12 subcarriers in each pilot tone channel estimation sequence.

Particularly, the specific implementation of step 2 can be:

By each pilot tone channel estimation sequence of determining for every antenna, carry out IFFT(inverse fast fourier transform, Inverse Fast Fourier Transform), and separate cyclic shift, obtain time domain pilot channel estimation sequence corresponding to each pilot tone channel estimation sequence.

Wherein, the information that comprises 12 subcarriers in each pilot tone channel estimation sequence, the information that comprises 12 sampled points in each time domain pilot channel estimation sequence.

If what step 1 obtained is 24 pilot tone channel estimation sequence, what step 2 obtained is 24 time domain pilot channel estimation sequence, and every reception antenna obtains respectively 8 time domain pilot channel estimation sequence.Wherein, for a reception antenna, 8 time domain pilot channel estimation sequence that this reception antenna is determined are respectively: the 1st transmit port and the 1st the time domain pilot channel estimation sequence that frequency pilot sign is corresponding that this reception antenna is determined, the 1st transmit port and the 2nd the time domain pilot channel estimation sequence that frequency pilot sign is corresponding, the 1st transmit port and the 3rd the time domain pilot channel estimation sequence that frequency pilot sign is corresponding, the 1st transmit port and the 4th the time domain pilot channel estimation sequence that frequency pilot sign is corresponding, the 2nd transmit port and the 1st the time domain pilot channel estimation sequence that frequency pilot sign is corresponding, the 2nd transmit port and the 2nd the time domain pilot channel estimation sequence that frequency pilot sign is corresponding, the 2nd transmit port and the 3rd the time domain pilot channel estimation sequence that frequency pilot sign is corresponding, and the 2nd transmit port and the 4th the time domain pilot channel estimation sequence that frequency pilot sign is corresponding.Wherein, the amplitude (i.e. 12 time domain pilot channel estimation values) that comprises 12 sampled points in each time domain pilot channel estimation sequence.

Particularly, in step 3, the noise equivalent power value of PUCCH channel can be determined by following steps:

According to each time domain pilot channel estimation sequence, determine the time domain pilot channel estimating power sequence that each time domain pilot channel estimation sequence is corresponding; For a time domain pilot channel estimating power sequence, determine in this time domain pilot channel estimating power sequence except first time domain channel estimating power value, the mean value of m time domain pilot channel estimating performance number of time domain channel estimating power value minimum, wherein m is positive integer; All mean values of being determined by each time domain pilot channel estimating power sequence are added or are averaged, as the noise equivalent power value of PUCCH channel.

Wherein, for a time domain pilot channel estimation sequence, 12 time domain pilot channel estimation values that comprise in this time domain pilot channel estimation sequence (i.e. the amplitude of 12 sampled points) are done respectively square, obtain 12 time domain pilot channel estimating performance numbers, using the sequence being formed by above-mentioned 12 time domain pilot channel estimating performance numbers as time domain pilot channel estimating power sequence corresponding to this time domain pilot channel estimation sequence.

For example, suppose that 12 time domain pilot channel estimation values that comprise in a time domain pilot channel estimation sequence are [a ₁, a ₂, a ₃, a ₄, a ₅, a ₆, a ₇, a ₈, a ₉, a ₁₀, a ₁₁, a ₁₂], 12 time domain pilot channel estimating performance numbers that comprise in time domain pilot channel estimating power sequence corresponding to this time domain pilot channel estimation sequence are [a ₁ ², a ₂ ², a ₃ ², a ₄ ², a ₅ ², a ₆ ², a ₇ ², a ₈ ², a ₉ ², a ₁₀ ², a ₁₁ ², a ₁₂ ²].

If what step 2 obtained is 24 time domain pilot channel estimation sequence, what step 3 obtained is 24 time domain pilot channel estimating power sequences, wherein, every reception antenna obtains respectively 8 time domain pilot channel estimating power sequences, comprises 12 time domain pilot channel estimating performance numbers (i.e. the squared magnitude of 12 sampled points) in each time domain pilot channel estimating power sequence.

Determining after time domain pilot channel estimating power sequence, for each time domain pilot channel estimating power sequence, determine respectively in this time domain pilot channel estimating power sequence except first time domain channel estimating power value the mean value of m time domain pilot channel estimating performance number of time domain channel estimating power value minimum.For example, the value of supposing m is that 12 time domain pilot channel estimating performance numbers that 4, one time domain pilot channel estimating power sequences comprise are [b ₁, b ₂, b ₃, b ₄, b ₅, b ₆, b ₇, b ₈, b ₉, b ₁₀, b ₁₁, b ₁₂], in this time domain pilot channel estimating power sequence, except first time domain channel estimating power value (b1), 4 time domain pilot channel estimating performance numbers of time domain channel estimating power value minimum are b ₉, b ₁₀, b ₁₁and b ₁₂, the definite mean value p of this time domain pilot channel estimating power sequence ₁for:

p ₁=（b ₉+b ₁₀+b ₁₁+b ₁₂）/4 [1]

Suppose that 24 definite mean values of time domain pilot channel estimating power sequence are respectively p ₁～p ₂₄, the noise equivalent power value P of the PUCCH channel of determining _noisefor:

$P_{\mathrm{noise}}=\underset{i=1}{\overset{24}{\mathrm{\Σ}}}{p}_i---\left[2\right]$

Or

$P_{\mathrm{noise}}=\frac{1}{24}\underset{i=1}{\overset{24}{\mathrm{\Σ}}}{p}_i---\left[3\right]$

Alternatively, in step 3, the noise equivalent power value of PUCCH channel also can be determined by following steps:

According to each time domain pilot channel estimation sequence, determine the time domain pilot channel estimating power sequence that each time domain pilot channel estimation sequence is corresponding; The time domain pilot channel estimating power sequence that in identical time slot, each frequency pilot sign is corresponding is merged, obtain new time domain pilot channel estimating power sequence; For a new time domain pilot channel estimating power sequence, determine in this new time domain pilot channel estimating power sequence except first time domain channel estimating power value, the mean value of m time domain pilot channel estimating performance number of time domain channel estimating power value minimum, wherein m is positive integer; All mean values of being determined by each new time domain pilot channel estimating power sequence are added or are averaged, as the noise equivalent power value of PUCCH channel.

Particularly, the time domain pilot channel estimating power sequence that in identical time slot, each frequency pilot sign is corresponding is merged, the specific implementation that obtains new time domain pilot channel estimating power sequence is: carry out respectively for every reception antenna: same correspondence definite this reception antenna transmit port and time domain pilot channel estimating power sequence corresponding to frequency pilot sign that belong to same time slot are merged, obtain each transmit port and new time domain pilot channel estimating power sequence corresponding to each time slot that this reception antenna is determined.

For example, suppose that the 1st time slot in a subframe that every reception antenna receives comprises the 1st frequency pilot sign (call number is 1) and the 2nd frequency pilot sign (call number is 5), the 2nd time slot comprises the 3rd frequency pilot sign (call number is 8) and the 4th frequency pilot sign (call number is 12), carries out respectively for every reception antenna:

The 1st transmit port and the 1st the time domain pilot channel estimating power sequence that frequency pilot sign is corresponding that this reception antenna is determined, the 1st transmit port and the 2nd time domain pilot channel estimating power sequence corresponding to frequency pilot sign determined with this reception antenna merge, and obtain the 1st transmit port and the 1st the new time domain pilot channel estimating power sequence that time slot is corresponding that this reception antenna is determined.

The 1st transmit port and the 3rd the time domain pilot channel estimating power sequence that frequency pilot sign is corresponding that this reception antenna is determined, the 1st transmit port and the 4th time domain pilot channel estimating power sequence corresponding to frequency pilot sign determined with this reception antenna merge, and obtain the 1st transmit port and the 2nd the new time domain pilot channel estimating power sequence that time slot is corresponding that this reception antenna is determined.

The 2nd transmit port and the 1st the time domain pilot channel estimating power sequence that frequency pilot sign is corresponding that this reception antenna is determined, the 2nd transmit port and the 2nd time domain pilot channel estimating power sequence corresponding to frequency pilot sign determined with this reception antenna merge, and obtain the 2nd transmit port and the 1st the new time domain pilot channel estimating power sequence that time slot is corresponding that this reception antenna is determined.
