Embodiment
The present inventor goes up the scheme that latter two code word bits of code word bits that the control information of transmission obtains after encoded punches to R-PUCCH in the prior art and carries out emulation, and the simulation result that obtains as shown in Figure 1.Wherein, simulation parameter is: modulation system is QPSK (Quadrature Phase ShiftKeying, Quadrature Phase Shift Keying), AWGN (Additive White Gaussian Noise, additive white Gaussian noise) channel.
By simulation result shown in Figure 1 as can be seen, when the information bit number is big, as at the information bit number be 11,12 and 13 o'clock the punching pattern pattern (optimal case shown in Figure 1) that punches with respect to optimum 0.6 decibel of performance loss about (dB) is arranged; And, be that 4 o'clock punching pattern also has performance loss about 0.4dB with respect to optimum punching pattern at the information bit number.Wherein, this optimum punching pattern refers to the corresponding optimum punching pattern of each information bit number.The optimum punching pattern of each information bit number correspondence can obtain by the following method, for example, for some information bit numbers, on the basis that provides the code word bits number that needs punching, code word after all punchings is gone out optimum code weight through computer search distribute, obtain the punching pattern that the code weight corresponding to optimum distributes then and be optimum punching pattern.
In view of this, one embodiment of the invention provides a kind of R-PUCCH to go up the coding method of the control information of transmission, and as shown in Figure 2, this method can comprise:
In the LTE-A system, the value of the bit number A of the information bit sequence of control information is 1 to 13 bit; (20, A) Ma encoder matrix can adopt the encoder matrix shown in the table 1, can keep the favorable compatibility with the LTE system.
In the present embodiment, the 13rd of the code word bits sequence of output in the step 210 and the 16th code word bits can be punched; Perhaps the 13rd and the 18th code word bits are punched.The simulation result of the punching pattern (scheme 3 shown in Figure 3) that Fig. 3 shows the punching pattern (scheme 2 shown in Figure 3) of destroying the 13rd and the 16th code word bits, destroy the 13rd and the 18th code word bits.Wherein, simulation parameter (condition) is identical with simulation parameter shown in Figure 1 (condition).
As seen from Figure 3, the optimum corresponding with each information bit number punching pattern (that is: shown in Figure 3 optimal case) is compared, being that the performance loss about 0.2dB was arranged in 8 o'clock at the information bit number only, is that the performance loss about 0.1dB was arranged in 10 o'clock at the information bit number.Therefore, adopt the coding method of present embodiment can improve the communication system overall performance; In addition, because all information bits adopt identical punching scheme now, can the simplification system design, be convenient to realize.
Below lift the process that several case descriptions obtain above-mentioned punching pattern again.The method flow schematic diagram of Fig. 4 shows that the embodiment of the invention provides a kind of pattern that obtains to punch, this method comprises:
Step 410 obtains the position of optimum punching code word bits of the information bit number correspondence of first priority.
In this step, on the basis of the given code word bits number (for example, the code word bits number of punching is 2) that need punch, can obtain all punching patterns of the information bit number correspondence of first priority; Go out the optimum code weight corresponding punching pattern that distributes by computer search then, with the position of the optimum punching code word bits of the information bit number correspondence that obtains first priority.In this step, more than one of the optimum punching of the information bit purpose of first priority pattern possibility; Therefore, the position possibility of the optimum of the information bit number correspondence of first priority punching code word bits is more than one.
In this step, the information bit number of first priority can be the highest information bit number of probability of occurrence or the highest information bit number of performance requirement.
Step 420 according to the optimum punch position of the information bit number correspondence of information bit purpose priority orders and a last priority, obtains the position of the optimum punching code word bits of out of Memory bit number correspondence successively.
In this step, the probability that this priority orders can occur according to the information bit number or performance requirement etc. sort.
In this step, the position of the optimum of the information bit number correspondence of a certain priority punching code word bits is middle selection the in position (more than one of possibility) of the optimum punching code word bits of the information bit number correspondence of a priority thereon; Like this, can guarantee that all information bit numbers adopt identical punching scheme, design with the simplification system.
One of ordinary skill in the art will appreciate that only probability or the performance requirement that occurs by the information bit number sorts, and may need further raising in some information bit purpose performance.For example, be example with the information bit number of R-PUCCH, only the probability that occurs with the information bit number sorts, and the priority orders that obtains is: { 4,6,8,9,11,2,1,3,5,7,10,12,13}.Shown in the simulation result scheme 1 as shown in Figure 3 of this punching pattern that obtains of putting in order.As seen from Figure 3, the punching pattern of scheme 1, bigger at the information bit number, as 11bits, when 12bits and 13bits, with respect to optimum punching scheme performance loss about 0.6dB is arranged.
Therefore, probability and the performance requirement that the information bit number occurs can be incorporated into line ordering.The information bit number of going up the control information of transmission with R-PUCCH is example, and according to performance requirement, the adjustment prioritization is: { 11,13,12,4,6,8,9,2,1,3,5,7,10}, perhaps { 13,11,12,4,6,8,9,2,1,3,5,7,10}.The simulation result of the punching pattern that obtains according to these two kinds of priority orders is shown in the scheme 2 and scheme 3 of Fig. 3.As seen from Figure 3, scheme 2 and scheme 3 are that the performance loss about 0.2dB was arranged in 8 o'clock at the information bit number only, are the performance loss about 0.1dB to be arranged at 10 o'clock at the information bit number, have kept good overall performance.
Obtain punching pattern shown in Figure 3, such as scheme 2 and scheme 3, also have other possible methods.Such as, obtain the position (that is: the optimum of each information bit number correspondence punching pattern) of the optimum punching code word bits of each information bit number correspondence at first respectively; Then common factor is got in the position of the optimum of all information bit number correspondences punching code word bits, also can obtain the punching pattern shown in the scheme 2 and scheme 3 among Fig. 3.Wherein, obtaining the method for the position of optimum punching code word bits for each information bit number can be referring among Fig. 4 shown in the step 410.
The R-PUCCH that Fig. 5 another embodiment of the present invention provides goes up the schematic flow sheet of the coding method of the control information of transmitting.As shown in Figure 5, this method can comprise:
