Description

PUCCH signal detection method and equipment

Technical Field

The present invention relates to the field of wireless communication technologies, and in particular, to a signal detection method and device for a PUCCH.

Background

In order to meet the requirements of LTE-a (Long Term Evolution-Advanced) downlink peak speed of 1Gbps and uplink peak speed of 500Mbps, a transmission bandwidth of 100MHz at maximum needs to be provided. Based on this, a solution of carrier aggregation is proposed, which aggregates 2 or more carrier units together to support a larger transmission bandwidth.

When the UE is in a carrier aggregation scenario, the UE (User Equipment) generally needs to feed back ACK/NACK (Acknowledgement/Negative Acknowledgement) information with more than 2 bits, and for this situation, the LTE-a introduces a PUCCH format3 (PUCCH format 3; PUCCH: Physical Uplink control channel) transmission format. The PUCCH format3 may transmit ACK/NACK information of at most 20 bits for feeding back PDSCH (Physical Downlink Shared Channel) reception of multiple subframes in multiple cells or TDD (Time division duplex) situations, so that correct detection of the PUCCH format3 signal has an important influence on Downlink transmission performance.

In the prior art, when detecting a PUCCH signal, whether the PUCCH signal is present is determined according to signals of all received symbols of the PUCCH. However, this method is only suitable for the case where the same information is carried on different subcarriers of the same OFDM (Orthogonal frequency division Multiplexing) symbol, and pucchfmat 1/1a/1b/2/2a/2b all satisfy this requirement, while different information is carried on different subcarriers of the same data symbol of PUCCH format3, for example, DFT (Discrete fourier transform) transform results carrying 12 QPSK (Quadrature Phase Shift Keying) modulation symbols on 12 subcarriers of the same data symbol of PUCCH format3 do not satisfy the requirement, and therefore, the above method in the prior art is not suitable for signal detection of PUCCH format 3.

In summary, the conventional technology cannot detect the PUCCH format3 signal.

Detailed Description

The scheme of the embodiment of the invention determines the equivalent noise power value and the equivalent signal power value of the PUCCH according to the received signal on the PUCCH pilot symbol, and determines to detect the PUCCH signal when the ratio of the determined equivalent signal power value to the equivalent noise power value is not less than a preset threshold value. Since the subcarriers of the pilot symbol of the PUCCH format3 do not carry modulation information, the scheme of the embodiment of the present invention may detect the PUCCH format3 signal.

The following embodiments of the present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.

The first embodiment is as follows:

as shown in fig. 1, a signal detection method for a PUCCH in an embodiment of the present invention includes the following steps:

step 101: and determining an equivalent noise power value and an equivalent signal power value of the PUCCH channel according to the received signal on the PUCCH pilot symbol.

Step 102: and when the ratio of the determined equivalent signal power value to the equivalent noise power value is not less than a preset threshold value, determining that the PUCCH signal is detected.

Wherein, step 101 can be realized by the following steps:

the method comprises the following steps: and aiming at one receiving antenna, determining a pilot symbol and a frequency domain pilot channel estimation sequence corresponding to a transmitting port according to a signal sequence on each PUCCH pilot symbol received on the receiving antenna and a pilot base sequence corresponding to each transmitting port.

Step two: each frequency domain pilot channel estimation sequence determined for each antenna is converted to a time domain pilot channel estimation sequence.

Step three: and determining an equivalent noise power value and an equivalent signal power value of the PUCCH according to each time domain pilot channel estimation sequence.

Specifically, the specific implementation manner of the step one may be:

performing for each receive antenna separately: and performing conjugate multiplication on the signal sequence on each PUCCH pilot symbol received on the receiving antenna and the pilot base sequence corresponding to each transmitting port respectively to obtain each pilot symbol determined by the receiving antenna and the frequency domain pilot channel estimation sequence corresponding to each transmitting port.

The conjugate multiplication of the signal sequence on the pilot symbol and the pilot base sequence means conjugate multiplication of an element in the signal sequence on the pilot symbol and a corresponding element in the pilot base sequence. For example, the first element in the signal sequence on the pilot symbol is conjugate-multiplied with the first element in the pilot base sequence, and the obtained value is used as the value of the first element in the frequency-domain pilot channel estimation sequence.

It should be noted that the transmission port in the embodiment of the present invention refers to a transmission port through which a transmitting end (for example, UE, user equipment) transmits a PUCCH signal, and each transmission port has a corresponding pilot base sequence. However, the PUCCH signal received by the receiving end (e.g., a base station) is a signal obtained by superimposing PUCCH signals transmitted by a plurality of transmitting ports, and therefore, the receiving end needs to detect the received PUCCH signal according to a pilot base sequence corresponding to each transmitting port to obtain the PUCCH signal transmitted by each port. The pilot base sequence corresponding to each transmission port may be generated by the base station according to preset parameters, or the base station may instruct the UE to generate and transmit the pilot base sequence to the base station according to preset parameters.

In a specific implementation process, after receiving a PUCCH signal through a receiving antenna, a receiving end processes data of one received subframe, where one subframe includes two slots, and for a Normal Cyclic Prefix (Normal CP), one slot includes 7 OFDM symbols. And numbering 14 OFDM symbols of the two time slots respectively to obtain indexes of 0-13 of the 14 OFDM symbols, wherein the first time Slot (Slot 1) comprises the OFDM symbols with indexes of 0-6, and the second time Slot (Slot 2) comprises the OFDM symbols with indexes of 7-13.

For one OFDM symbol, it may be a pilot symbol or a data symbol. The pilot symbols refer to OFDM symbols used for transmitting reference signals in one subframe; the data symbols refer to OFDM symbols except for pilot symbols in one subframe. In one subframe, the index numbers of the data symbols are 0, 2, 3, 4, 6, 7, 9, 10, 11, and 13, assuming that the index numbers of the pilot symbols are 1, 5, 8, and 12. Wherein, the index numbers of the pilot symbols included in the 1 st slot are 1 and 5, the index numbers of the data symbols included in the 1 st slot are 0, 2, 3, 4 and 6, the index numbers of the pilot symbols included in the 2 nd slot are 8 and 12, and the index numbers of the data symbols included in the 2 nd slot are 7, 9, 10, 11 and 13. I.e. one sub-frame contains 4 pilot symbols and 10 data symbols and each slot contains 2 pilot symbols and 5 data symbols.

Based on this, each receiving antenna can receive 4 pilot symbols and 10 data symbols each time, wherein the 1 st pilot symbol and the 2 nd pilot symbol received by the receiving antenna belong to the 1 st time slot, the 1 st to 5 th data symbols received by the receiving antenna belong to the 1 st time slot, the 3 rd pilot symbol and the 4 th pilot symbol received by the receiving antenna belong to the 2 nd time slot, and the 6 th to 10 th data symbols received by the receiving antenna belong to the 2 nd time slot.

It should be noted that one frequency domain OFDM symbol includes information of 12 subcarriers, and one time domain OFDM symbol obtained by transforming the frequency domain OFDM symbol into a time domain includes information of 12 sampling points (or called paths). The embodiment of the invention describes the information of 12 subcarriers or sampling points contained in a pilot symbol or a data symbol by using a sequence with the length of 12, wherein a time domain sequence contains the information of 12 sampling points, and a frequency domain sequence contains the information of 12 subcarriers.

Based on this, in the step one, the length of the signal sequence on each PUCCH pilot symbol, the pilot base sequence corresponding to each transmission port, and each frequency domain pilot channel estimation sequence is 12, and includes information of 12 subcarriers.

Assuming that a subframe received by one receiving antenna includes 4 pilot symbols and 2 transmitting ports transmit PUCCH signals, 4 × 2=8 frequency domain pilot channel estimation sequences may be determined for the receiving antenna, where the 8 frequency domain pilot channel estimation sequences determined by the receiving antenna are: the receiving antenna determines a frequency domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 1 st pilot symbol, a frequency domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 2 nd pilot symbol, a frequency domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 3 rd pilot symbol, a frequency domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 4 th pilot symbol, a frequency domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 1 st pilot symbol, a frequency domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 2 nd pilot symbol, a frequency domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 3 rd pilot symbol, and a frequency domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 4 th pilot symbol.

Assuming that there are 3 receiving antennas in total, 3 × 4 × 2=24 frequency domain pilot channel estimation sequences can be finally obtained, where each receiving antenna obtains 8 frequency domain pilot channel estimation sequences, and each frequency domain pilot channel estimation sequence includes information of 12 subcarriers.

Specifically, the specific implementation manner of step two may be:

and performing IFFT (Inverse Fast Fourier Transform) on each frequency domain pilot channel estimation sequence determined by each antenna, and performing cyclic shift de-solving to obtain a time domain pilot channel estimation sequence corresponding to each frequency domain pilot channel estimation sequence.

Each frequency domain pilot channel estimation sequence comprises information of 12 subcarriers, and each time domain pilot channel estimation sequence comprises information of 12 sampling points.

If the first step obtains 24 frequency domain pilot channel estimation sequences, the second step obtains 24 time domain pilot channel estimation sequences, and each receiving antenna respectively obtains 8 time domain pilot channel estimation sequences. For a receiving antenna, the 8 time domain pilot channel estimation sequences determined by the receiving antenna are respectively: the receiving antenna determines a time domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 1 st pilot symbol, a time domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 2 nd pilot symbol, a time domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 3 rd pilot symbol, a time domain pilot channel estimation sequence corresponding to a 1 st transmitting port and a 4 th pilot symbol, a time domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 1 st pilot symbol, a time domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 2 nd pilot symbol, a time domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 3 rd pilot symbol, and a time domain pilot channel estimation sequence corresponding to a 2 nd transmitting port and a 4 th pilot symbol. Wherein, each time domain pilot channel estimation sequence includes the amplitude of 12 sampling points (i.e. 12 time domain pilot channel estimation values).

Specifically, the equivalent noise power value of the PUCCH channel in step three may be determined by:

determining a time domain pilot channel estimation power sequence corresponding to each time domain pilot channel estimation sequence according to each time domain pilot channel estimation sequence; aiming at a time domain pilot channel estimation power sequence, determining the average value of m time domain pilot channel estimation power values with the minimum time domain channel estimation power value except the first time domain channel estimation power value in the time domain pilot channel estimation power sequence, wherein m is a positive integer; and adding or averaging all the average values determined by each time domain pilot channel estimation power sequence to obtain an equivalent noise power value of the PUCCH.

For a time domain pilot channel estimation sequence, respectively squaring 12 time domain pilot channel estimation values (namely amplitudes of 12 sampling points) contained in the time domain pilot channel estimation sequence to obtain 12 time domain pilot channel estimation power values, and taking a sequence consisting of the 12 time domain pilot channel estimation power values as a time domain pilot channel estimation power sequence corresponding to the time domain pilot channel estimation sequence.

For example, assume that 12 time-domain pilot channel estimation values included in one time-domain pilot channel estimation sequence are [ a ]₁、a₂、a₃、a₄、a₅、a₆、a₇、a₈、a₉、a₁₀、a₁₁、a₁₂]Then 12 time domain pilot channel estimation power values contained in the time domain pilot channel estimation power sequence corresponding to the time domain pilot channel estimation sequence are [ a ]₁ ²、a₂ ²、a₃ ²、a₄ ²、a₅ ²、a₆ ²、a₇ ²、a₈ ²、a₉ ²、a₁₀ ²、a₁₁ ²、a₁₂ ²]。

If the second step obtains 24 time domain pilot channel estimation sequences, the third step obtains 24 time domain pilot channel estimation power sequences, wherein each receiving antenna obtains 8 time domain pilot channel estimation power sequences, and each time domain pilot channel estimation power sequence contains 12 time domain pilot channel estimation power values (namely the square of the amplitude of 12 sampling points).

After determining the time domain pilot channel estimation power sequence, respectively determining the value of the time domain pilot channel estimation power except the first time domain channel estimation power value in the time domain pilot channel estimation power sequence for each time domain pilot channel estimation power sequenceAnd the average value of the m time domain pilot channel estimation power values with the minimum time domain channel estimation power value. For example, assuming that m is 4, 12 time domain pilot channel estimation power values contained in one time domain pilot channel estimation power sequence are [ b₁、b₂、b₃、b₄、b₅、b₆、b₇、b₈、b₉、b₁₀、b₁₁、b₁₂]In the time domain pilot channel estimation power sequence, except the first time domain channel estimation power value (b 1), the 4 time domain pilot channel estimation power values with the minimum time domain channel estimation power value are b₉、b₁₀、b₁₁And b₁₂Then the average value p determined by the time domain pilot channel estimation power sequence₁Comprises the following steps:

p₁=（b₉+b₁₀+b₁₁+b₁₂）/4 [1]

suppose that the average values determined by the 24 time domain pilot channel estimation power sequences are respectively p₁～p₂₄Determining the equivalent noise power value P of the PUCCH channel_noiseComprises the following steps:

or

Optionally, the equivalent noise power value of the PUCCH channel in step three may also be determined by:

determining a time domain pilot channel estimation power sequence corresponding to each time domain pilot channel estimation sequence according to each time domain pilot channel estimation sequence; combining the time domain pilot channel estimation power sequences corresponding to each pilot symbol in the same time slot to obtain a new time domain pilot channel estimation power sequence; aiming at a new time domain pilot channel estimation power sequence, determining the average value of m time domain pilot channel estimation power values with the minimum time domain channel estimation power value except a first time domain channel estimation power value in the new time domain pilot channel estimation power sequence, wherein m is a positive integer; and adding or averaging all the average values determined by each new time domain pilot channel estimation power sequence to obtain the equivalent noise power value of the PUCCH.

Specifically, the specific implementation manner of combining the time domain pilot channel estimation power sequences corresponding to each pilot symbol in the same time slot to obtain a new time domain pilot channel estimation power sequence is as follows: performing for each receive antenna separately: and combining the time domain pilot channel estimation power sequences corresponding to the pilot symbols which correspond to the same transmitting port and belong to the same time slot and are determined by the receiving antenna to obtain a new time domain pilot channel estimation power sequence corresponding to each transmitting port and each time slot which are determined by the receiving antenna.

For example, assuming that the 1 st slot in one subframe received by each receiving antenna includes the 1 st pilot symbol (index number is 1) and the 2 nd pilot symbol (index number is 5), and the 2 nd slot includes the 3 rd pilot symbol (index number is 8) and the 4 th pilot symbol (index number is 12), then the following steps are performed for each receiving antenna respectively:

and combining the time domain pilot channel estimation power sequence corresponding to the 1 st transmitting port and the 1 st pilot symbol determined by the receiving antenna with the time domain pilot channel estimation power sequence corresponding to the 1 st transmitting port and the 2 nd pilot symbol determined by the receiving antenna to obtain a new time domain pilot channel estimation power sequence corresponding to the 1 st transmitting port and the 1 st time slot determined by the receiving antenna.

And combining the time domain pilot channel estimation power sequence corresponding to the 1 st sending port and the 3 rd pilot symbol determined by the receiving antenna with the time domain pilot channel estimation power sequence corresponding to the 1 st sending port and the 4 th pilot symbol determined by the receiving antenna to obtain a new time domain pilot channel estimation power sequence corresponding to the 1 st sending port and the 2 nd time slot determined by the receiving antenna.

And combining the time domain pilot channel estimation power sequence corresponding to the 2 nd transmitting port and the 1 st pilot symbol determined by the receiving antenna with the time domain pilot channel estimation power sequence corresponding to the 2 nd transmitting port and the 2 nd pilot symbol determined by the receiving antenna to obtain a new time domain pilot channel estimation power sequence corresponding to the 2 nd transmitting port and the 1 st time slot determined by the receiving antenna.

And combining the time domain pilot channel estimation power sequence corresponding to the 2 nd transmitting port and the 3 rd pilot symbol determined by the receiving antenna with the time domain pilot channel estimation power sequence corresponding to the 2 nd transmitting port and the 4 th pilot symbol determined by the receiving antenna to obtain a new time domain pilot channel estimation power sequence corresponding to the 2 nd transmitting port and the 2 nd time slot determined by the receiving antenna.

The merging of the two sequences means adding values of corresponding elements in the two sequences, for example, adding a value of a 1 st element in a 1 st sequence to a value of a 1 st element in a 2 nd sequence to obtain a value of the 1 st element in the merged sequence.

For example, for one receiving antenna, it is assumed that the time domain pilot channel estimation power sequence corresponding to the 1 st transmitting port and the 1 st pilot symbol determined by the receiving antenna is [ b ]₁、b₂、b₃、b₄、b₅、b₆、b₇、b₈、b₉、b₁₀、b₁₁、b₁₂]The estimated power sequence of the time domain pilot channel corresponding to the 1 st transmitting port and the 2 nd pilot symbol determined by the receiving antenna is [ c ]₁、c₂、c₃、c₄、c₅、c₆、c₇、c₈、c₉、c₁₀、c₁₁、c₁₂]Then the 1 st sending port determined by the receiving antenna is obtainedThe new time domain pilot channel estimation power sequence corresponding to the 1 st time slot is [ b ]₁+c₁、b₂+c₂、b₃+c₃、b₄+c₄、b₅+c₅、b₆+c₆、b₇+c₇、b₈+c₈、b₉+c₉、b₁₀+c₁₀、b₁₁+c₁₁、b₁₂+c₁₂]。

Based on this, each receiving antenna can determine 4 new time domain pilot channel estimation power sequences, and 3 receiving antennas can determine 12 new time domain pilot channel estimation power sequences.

Assuming that a subframe received by a receiving antenna contains 10 data symbols and 2 transmitting ports transmit PUCCH signals, 10 × 2=20 frequency domain data transmission signal sequences are determined for the receiving antenna. Assuming that there are 3 receiving antennas in total, 3 × 10 × 2=60 frequency domain data transmission signal sequences can be finally obtained, where each receiving antenna obtains 20 frequency domain data transmission signal sequences, and each frequency domain data transmission signal sequence includes information of 12 subcarriers.

Based on this, 4 second frequency-domain modulated signal estimation sequences can be determined for each receiving antenna, and 12 second frequency-domain modulated signal estimation sequences can be determined for 3 receiving antennas.

After determining the second frequency domain modulation signal estimation sequences corresponding to each transmission port and each time slot for each receiving antenna, the second frequency domain modulation signal estimation sequences corresponding to the same time slot in all the determined second frequency domain modulation signal estimation sequences may be added to obtain a third frequency domain modulation signal estimation sequence corresponding to each time slot.

And then, modulus values of all frequency domain modulation signal estimation values in all third frequency domain modulation signal estimation sequences are taken and added or averaged to obtain an equivalent signal power value of the PUCCH.

Optionally, after determining the second frequency domain modulation signal estimation sequences corresponding to each transmission port and each slot for each receiving antenna, the second frequency domain modulation signal estimation sequences corresponding to the same slot in all the determined second frequency domain modulation signal estimation sequences may be added and averaged to obtain a fourth frequency domain modulation signal estimation sequence corresponding to each slot, and the modulus values of the frequency domain modulation signal estimation values in all the fourth frequency domain modulation signal estimation sequences are added or averaged to obtain the equivalent signal power value of the PUCCH channel.
