Description

Technical Field

[0001] The present invention relates to the field of mobile communications, and in particular to a method and device for determining the number of decoder iterations. Background Art

[0002] In mobile communication systems, decoders are used for bit-level processing, such as 5G's Low Density Parity Check Code (LDPC) decoder, 4G's Turbo decoder or convolution decoder, etc. The performance of these decoders is closely related to the number of iterations. Generally speaking, the more iterations, the better the performance. However, the decoder capacity is fixed under certain conditions. If a fixed number of iterations strategy is used, the decoder capacity will be wasted. For example, when the system capacity is small, the decoder's maximum performance cannot be exerted; or the number of iterations cannot be reasonably configured at the beginning. Too small or too large may cause the system capacity to decrease or even cause the system to crash.

[0003] Therefore, under the condition of variable system capacity, it is necessary to find a method to optimally configure the number of decoder iterations in order to maximize the use of the decoder's capabilities and improve the performance indicators of the mobile communication system.

[0004] Regarding the problem of how to configure the number of decoder iterations when the system capacity varies in the related art, no solution has been proposed yet. Summary of the invention

[0012] A classification module, used for classifying the virtual CB;

This can solve the problem of how to configure the number of iterations of the decoder in the case of variable system capacity in the related art.

[0061] Acquire the new transmission TB that needs to be processed in the current processing time period, calculate the number of CBs included in the new transmission TB, and virtualize the number of CBs (i.e., multiply the number of CBs by a virtual factor) to obtain the virtual number of CBs of the new transmission TB;

[0062] The retransmission TB that needs to be processed in the current processing time period is obtained, the position and number of CBs that need to be actually processed by the retransmission TB are calculated, and the number of CBs is virtualized to obtain the number of virtual CBs of the retransmission TB.

[0063] The embodiment of the present invention provides an adaptive method for determining the number of decoding iterations, which can better utilize the capabilities of a decoder and is applicable to a bit-level processing link in mobile communications, including:

[0064] 1. CB number virtualization processing, including:

[0065] 1) Calculate the virtualized number of new transmission CB blocks to be processed in this processing time period, specifically including: collect the new transmission TBs to be processed in this processing time period, calculate the number of CBs contained in each new transmission TB, and multiply the number of CBs by the virtual factor to calculate the number of virtual CBs of this TB (the virtualized CBs are hereinafter referred to as virtual CBs);

[0067] 2. Calculate the initial number of iterations for each type of CB, including:

[0068] 1) Classify the virtual CBs in this processing time period and set the minimum and maximum iteration limits for each type of virtual CB;

[0069] 2) Calculating the initial iteration number of the remaining virtual CBs, including: calculating the initial iteration number of all virtual CBs within this period of time according to the working frequency of the decoder, the number of cycles corresponding to a single iteration of the decoder required for each virtual CB, and the decoding time allocated by the system;

[0070] 3) calculating the initial number of iterations of the first type of virtual CB, including: comparing the maximum number of iterations set for the first type of virtual CB with the initial number of iterations of the remaining types of virtual CBs to obtain a minimum value, comparing the minimum value with the minimum number of iterations configured for this type of virtual CB, taking the maximum value, and obtaining the initial configuration iteration number of the first type of virtual CB block;

[0071] 4) Calculate the initial iteration number of the second type of virtual CB, including:

[0072] The time required for the calculated initial configuration iteration number of the first type of virtual CB is removed from the overall decoding time, and the initial iteration number of all virtual CBs of the remaining types is calculated according to the remaining decoding time, the parameters of the remaining types of virtual CBs and their corresponding decoders (matrix size, matrix type, expansion factor and single iteration cycle number), and the maximum number of iterations set for the second type of virtual CB is compared with the initial number of iterations of all virtual CBs of the remaining types to obtain the minimum value, and the minimum value is compared with the minimum number of iterations configured for this type of virtual CB, and the maximum value is taken to obtain the initial configuration iteration number of the second type of virtual CB block;

[0073] 5) Calculate the number of initial configuration iterations of the third type of virtual CB, including:

[0074] The time required for the initial configuration iterations of the first and second virtual CBs calculated respectively is removed from the overall decoding time. The initial iterations of all virtual CBs of the remaining classes are calculated according to the remaining decoding time, the parameters of the remaining virtual CBs and their corresponding decoders (matrix size, matrix type, expansion factor, and number of single iteration cycles). The maximum number of iterations set for the third virtual CB is compared with the initial number of iterations of all virtual CBs of the remaining classes to obtain the minimum value. The minimum value is compared with the minimum number of iterations configured for this type of virtual CB, and the maximum value is taken to obtain the initial configuration iteration number of the third virtual CB block.

[0075] 6) By analogy, the initial configuration iteration times of the remaining virtual CBs of other classes are obtained in turn.

[0076] The specific implementation of the present invention is described in detail below by taking m+n TBs scheduled in one slot as an example.

[0077] Assume that this slot includes: the number of newly transmitted TBs is m and the number of retransmitted TBs is n; the number of all initially available cycles allocated for decoding in one slot is S.

[0078] The number of cycles that the decoder processes in a single iteration indexed by TB (including new transmission TB and retransmission TB) is: X0, X1, X2, ..., X m-1 ,X m ,X m+1 ,X m+2 ,......,X m+n-1 ;

[0079] The number of new transmission CBs of TB (including new transmission TB and retransmission TB) is C0, C1, ..., C m-1 , C m , C m+1, ..., C m+n+1 ;

[0080] The virtual factors of new TB are: α0, α1, α2, ..., α m-1 ;

[0081] The virtual factor of the new transmission TB can be calculated according to the position of the time when each TB starts the i-th CB block of this TB in the entire available cycle. Assuming that the time when the i-th new transmission TB starts the calculation of the i-th CB block of this TB is Ti, then

[0082] α i =(S / T i )*C i

[0083] Then the number of virtual CBs of the new TB is: α0*C0, α1*C1, α2*C2, ..., α m-1 *C m-1 ;

[0084] The number of CBs that were decoded incorrectly last time by the retransmitted TB is O0, O1, O2, ..., O n-1 ;

[0085] The virtual factor of the retransmitted TB can also be calculated according to the position of the time when each TB starts calculating the i-th CB block of this TB in the entire available period, which is: β0, β1, β2, ..., β n-1 ;

[0086] Then the number of virtual CBs for retransmitting TB is: β0*O0, β1*O1, β2*O2, ..., β n-1 *O n-1 ;

[0087] Virtual CBs are divided into multiple categories, for example, into three categories:

[0088] The virtual CB included in the new TB is of the first type, assuming that its iteration number range is [MIN0:MAX0];

[0089] The virtual CBs included in the TBs with a retransmission error rate <= 10% are of the second type, and it is assumed that there are p TBs with a retransmission error rate < 10%, and the number of iterations is in the range of [MIN1:MAX1];

[0090] The virtual CBs included in the TBs with a retransmission error rate greater than 10% are of the third category, and the number of TBs with a retransmission error rate greater than 10% is np, and the range of its iteration times is [MIN2:MAX2];

[0091] Use the available cycle calculation unit and the first-level iteration calculation unit to calculate the initial iteration number E0 of all virtual CBs according to the following formula:

[0092]

[0093] Use the secondary iteration number calculation unit to compare MAX0 and E0, take the smaller value F0, and compare F0 and MIN0, take the larger value, and obtain the iteration number L0 of the first type of virtual CB in the decoder;

[0094] Continue to use the first-level iteration number calculation unit to calculate the initial iteration number E1 of the second type of virtual CB according to the following formula:

[0095]

[0096] Continue to use the secondary iteration number calculation unit, compare MAX1 and E1, take the smaller value as F1, and compare F1 and MIN1, take the larger value, and you can get the iteration number L1 of the second type CB block in the decoder;

[0097] Continue to use the available cycle calculation unit and the first-level iteration number calculation unit to calculate the initial iteration number E2 of the third type of virtual CB according to the following formula:

[0098]

[0099] Continue to use the secondary iteration number calculation unit, compare MAX2 and E2, take the smaller value as F2, and compare F2 and MIN2, take the larger value, and get the iteration number L2 of the third type of virtual CB in the decoder;

[0100] Depending on the number of iterations configured for each CB block, parallel decoding or serial decoding is performed until all CBs in this slot are decoded.

[0101] Through the embodiment of the present invention, a method of classifying and calculating the number of CB iterations after virtualizing the CB of each TB is adopted, so that the number of decoder iterations can be adaptively configured for the TB, thereby greatly improving the throughput utilization of the decoder, thereby improving the performance of the entire mobile communication system.

[0102] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course can also be implemented by hardware, but in many cases the former is a better implementation method. Based on such an understanding, the technical solution of the present invention, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, a magnetic disk, or an optical disk), and includes a number of instructions for enabling a terminal device (which can be a mobile phone, a computer, a server, or a network device, etc.) to execute the methods described in each embodiment of the present invention.
