All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the description of the embodiments of the invention, the terms "first", "second", and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance, nor order.
The following describes a method and an apparatus for detecting a physical uplink control channel according to the present invention with reference to fig. 1 to 5.
Fig. 1 is a flowchart illustrating a method for detecting a physical uplink control channel according to the present invention. As shown in fig. 1, an execution subject of the method for detecting a physical uplink control channel according to the embodiment of the present invention may be a device for detecting a physical uplink control channel, where the method includes: step 101, step 102, step 103 and step 104.
Step 101, determining a local sequence corresponding to the first cyclic shift value and a local sequence corresponding to the second cyclic shift value based on the two values of the parameter for determining the cyclic shift and the initial offset value of the target user equipment.
Wherein the first cyclic shift value and the second cyclic shift value correspond to two values of a parameter for determining cyclic shift, respectively; the first pair of cyclic shift values has a value applied to a parameter determining the cyclic shift that is less than a value applied to a parameter determining the cyclic shift by the second pair of cyclic shift values.
Specifically, the method for detecting a physical uplink control channel provided in the embodiment of the present invention may be used for detecting a physical uplink control channel, and may complete the whole detection process in a frequency domain, and less channels may be reserved for noise calculation. The whole detection process is completed in the frequency domain, and can include the calculation of signal power and noise algorithms. The invention adopts pure frequency domain detection, fully utilizes a plurality of cyclic shifts distributed to single UE by a mobile communication protocol, and detects the power of signals and noise, thereby realizing the detection of the PUCCH. The apparatus for detecting a physical uplink control channel may be a base station.
Preferably, the method for detecting a physical uplink control channel provided in the embodiment of the present invention may be used to detect a format of a 5G PUCCH format 0.
The 5G PUCCH format0 belongs to a format of an uplink channel PUCCH, occupies 1-2 symbols, carries 1-2 bit UCI information, and can carry Scheduling Request (SR) and hybrid automatic repeat Request response (HARQ).
The Hybrid Automatic repeat Request Acknowledgement may include a Hybrid Automatic repeat Request Acknowledgement (HARQ-ACK) and a Hybrid Automatic repeat Request negative Acknowledgement (HARQ-NACK).
The 5G PUCCH format0 can transmit 1-bit SR, 1-bit HARQ-ACK, 2-bit HARQ-ACK, SR and 1-bit HARQ-ACK multiplexing, SR and 2-bit HARQ-ACK multiplexing and the like.
The detection method of the physical uplink control channel provided by the embodiment of the invention is not only suitable for the situation of 1-bit HARQ-ACK transmission, but also suitable for the situations of 2-bit HARQ-ACK, SR and 1-bit HARQ-ACK multiplexing, SR and 2-bit HARQ-ACK and the like. The processing steps and methods of the above various situations are consistent, and the embodiment of the present invention describes the PUCCH detection process in detail by taking HARQ-ACK for transmitting 1bit as an example.
A parameter mcs for determining a cyclic shift for indicating the number of bits of the cyclic shift.
The initial offset value m0 of the target user equipment, which is used to indicate the number of bits of the initial cyclic shift of the target user equipment.
The initial offset value m0 is a pre-configured parameter and can be configured through high-layer signaling. Specifically, the initial offset value m0 may be directly indicated by higher layer signaling, or may be obtained by configuration of higher layer signaling or implicitly indicated.
The parameter mcs for determining the cyclic shift and the initial offset value m0 may have values ranging from 0 to 11.
For the situation of transmitting 1-bit HARQ-ACK of only 1bit, the mcs takes values of 0 and 6 according to the specification of 38.213 protocol; the re-bonding layer assigned m0, according to the 38.213 protocol specification, can calculate the cyclic shifts α _1 and α _2 for the two values 0 and 6; further, according to the protocol specification of 38.213, based on the cyclic shift values α _1 and α _2, the local sequences corresponding to the two cyclic shift values (that is, the local sequence corresponding to the cyclic shift value α _1 and the local sequence corresponding to the cyclic shift value α _2) can be obtained.
Where α _1 represents a first cyclic shift value and α _2 represents a second cyclic shift value.
It can be understood that the layer refers to the L2 layer of a base station, i.e., the Mac (Multiple Access Channel) layer.
The local sequence is a sequence that is pre-allocated locally to the detection apparatus of the physical uplink control channel. In the 5G PUCCH format0 scenario, the number of local sequences is 12, and the determination of the local sequence corresponding to the cyclic shift value indicates which of the 12 sequences is determined to be the local sequence corresponding to the cyclic shift value.
102, acquiring a first power based on the received frequency domain data of the physical uplink control channel sent by the target user equipment and a local sequence corresponding to a first cyclic shift value, and acquiring a second power based on the frequency domain data and the local sequence corresponding to a second cyclic shift value;
specifically, in the process of completing detection in the frequency domain, the algorithms for calculating power are consistent, the frequency domain data is multiplied by the local sequence in a conjugate mode, all real parts and imaginary parts are correspondingly accumulated to obtain an average value, and then the real parts and the imaginary parts are respectively squared and added to sum.
Conjugate multiplication is carried out on the received frequency domain data and a local sequence corresponding to alpha _1, the real part and the imaginary part of the multiplication result are averaged after corresponding accumulation according to Resource Elements (RE), and the sum of the square of the real part and the square of the imaginary part of the averaging result is obtained to obtain first power P (alpha _ 1); and (3) the received frequency domain data is multiplied by the local sequence conjugate corresponding to alpha _2, the real part and the imaginary part of the multiplied result are averaged after the real part and the imaginary part are correspondingly accumulated according to the resource elements, and the square of the real part and the square of the imaginary part of the averaged result are summed to obtain the second power P (alpha _ 2).
The calculation formula can be as follows
Figure BDA0003619970690000091
P(α)＝||Z(α)||
Wherein Z (alpha) represents the result of averaging after accumulation; n represents an index of an RE of a single PRB; y (n) represents the received frequency domain data; x (k) represents a local sequence; superscript H denotes conjugation; p (α) represents power.
It is understood that, in the case where α in the above formula is α _1, x (k) represents the local sequence corresponding to α _1, and P (α) is the first power P (α _ 1); in the above formula, when α is α _2, x (k) represents a local sequence corresponding to α _2, and P (α) is the second power P (α _ 2).
Step 103, determining the larger one of the first power and the second power as the total power, and obtaining the noise power based on the larger one of the first power and the second power.
Wherein, the total power is the sum of the signal power and the noise power.
Specifically, the first power P (α _1) and the second power P (α _2) may be compared in magnitude, and the larger one of them may be determined as the total power, i.e., as the sum of the signal power and the noise power.
Based on the larger of the first power P (α _1) and the second power P (α _2), the signal portion thereof is extracted as specified by the 38.213 protocol, so that the noise power can be obtained.
And 104, acquiring the signal-to-noise ratio of the physical uplink control channel based on the total power and the noise power.
Specifically, the signal power can be obtained by subtracting the noise power from the total power.
After the signal power is obtained, the signal power is divided by the noise power, so that the signal-to-noise ratio of the PUCCH can be obtained, and UCI information transmitted by the UE can be blindly detected.
It should be noted that the PUCCH detection method provided in the embodiments of the present invention reduces complexity of steps, does not need to perform cell-level cyclic shift and obtain corresponding power according to the cyclic shift, reduces a procedure of steps, does not need to perform IDFT, simplifies complexity of calculation, can reduce loads of hardware such as a CPU, and can detect a result more quickly and improve detection efficiency under the condition that performance of the CPU is the same.

Specifically, the local sequence corresponding to the third cyclic shift value α _3 may be determined according to the 38.213 protocol specification based on the cyclic shift value for the larger of the first power P (α _1) and the second power P (α _ 2).
If the larger one of the first power P (α _1) and the second power P (α _2) is the first power P (α _1), the cyclic shift value may be α _1 based on the value of the cyclic shift used for the larger one of the first power P (α _1) and the second power P (α _ 2); if the larger one of the first power P (α _1) and the second power P (α _2) is the first power P (α _2), the cyclic shift value may be α _2 based on the value for the larger one of the first power P (α _1) and the second power P (α _ 2).
And acquiring noise power based on the frequency domain data and the local sequence corresponding to the third cyclic shift value.
Specifically, the method for obtaining the noise power based on the local sequence corresponding to the frequency domain data and the third cyclic shift value is consistent with the method for obtaining the first power based on the local sequence corresponding to the frequency domain data and the first cyclic shift value, and the method for obtaining the second power based on the local sequence corresponding to the frequency domain data and the second cyclic shift value, and is not repeated here.

Specifically, the fourth cyclic shift value may be obtained by adding a preset target offset to the first cyclic shift value and the second cyclic shift value on the basis of the cyclic shift value used for obtaining the larger one of the first power and the second power.
The preset target offset amount may be any integer greater than or equal to 1 and less than or equal to 11. The embodiment of the present invention is not particularly limited to a specific value of the target offset.
After the fourth cyclic shift value is obtained, the fourth cyclic shift value may be modulo divided by the number of local sequences to obtain a third cyclic shift value α _ 3.
Exemplarily, in a 5G PUCCH format0 scenario, the number of local sequences is 12, and the fourth cyclic shift value may be modulo-divided by 12.
And determining a local sequence corresponding to the third cyclic shift value based on the third cyclic shift value.
Specifically, according to the 38.213 protocol, based on the third cyclic shift value α _3, the local sequence corresponding to the third cyclic shift value α _3 can be obtained.
