Abstract
The invention discloses an encoding method of a 3G mobile communication system and a sending and receiving method thereof, and the encoding method is used for encoding the 3G mobile communication system and encoding filling bits of a code block segmentation treatment unit during the multiplexing process. The technical scheme is as follows: encoding the 3G mobile communication system, encoding the filling bits of the code block segmentation treatment unit during the multiplexing process, and taking information which is associated with input bits of a plurality of transmission blocks as the filling bits.
Description
Technical field
The present invention relates to improve in a kind of 3-G (Generation Three mobile communication system) (being called for short " 3G mobile communication system ") code processing method of transmission performance, relate in particular to the code processing method that a kind of filling bit that utilizes code block segmentation and radio frames size equilibrium treatment to add improves transmission performance in the chnnel coding process.
Background technology
Along with the process of global economic integration and social informatization, mobile communication business and mobile communication subscriber are the trend of rapid growth, and mobile communication is individualized, intelligent in order to adapt to, the demand of multimedization, has proposed 3-G (Generation Three mobile communication system).Existing 3G system standard mainly comprises WCDMA, TD-SCDMA and CDMA2000, and preceding two standards are mainly promoted by the 3GPP tissue, and the latter is promoted by 3GPP2.Along with the continuous development of the communication technology and user raising day by day to quality of service requirement, the 3G (Third Generation) Moblie standard of initial version can not satisfy user's needs, therefore constantly evolution forward, such as HSDPA is exactly a kind of enhanced scheme that 3GPP Release 5 proposes, main purpose is the high speed support to Packet data service, and obtains lower time delay, higher throughput of system and stronger QoS and guarantee; And the HSUPA that proposes at Release 6 is exactly in the corresponding high speed data transfer agreement of up direction.
In order to guarantee data block efficient and transmission reliably on Radio Link, physical layer need be encoded and multiplexing to the data block that the upper strata is transmitted, and then the position that is mapped to the physical channel correspondence sends.And various 3G standards, especially WCDMA and TD-SCDMA have similitude aspect a lot.Be example with the TD-SCDMA standard below, simply introduce its common transport channel coding and multiplex process, as shown in Figure 1: in a Transmission Time Interval TTI (Transmission Time Interval), be admitted to chnnel coding and Multiplexing module from the data of different transmission channels with the form of data block, after the process steps of processing, be mapped to physical channel:
-add CRC for each transmission block;
-transmission block cascade/code block segmentation;
-chnnel coding;
The equilibrium of-radio frames size;
-(in two steps) interweaves;
-radio frame segmentation;
-rate-matched;
-transmission channel multiplexing;
-bit scramble;
The segmentation of-physical channel;
The segmentation of-subframe;
-be mapped to physical channel;
In above-mentioned steps, after the transmission block cascade among the TTI is finished, if total bit number A of transmission block greater than the maximum length K of an encoding block, then needs to carry out code block segmentation behind the transmission block cascade.What the full-size of code block will depend on the transmission channel use is that convolutional encoding, Turbo encode or do not encode:
(1) convolutional encoding: K=504;
(2) Turbo coding: K=5114;
(3) do not encode: K without limits.
When A＞K, need carry out code block segmentation to transmission block, the length X of C the code block that obtains after the segmentation is equal to each other, if A is not the integral multiple of C, then the front end at transmission block inserts filling bit, and filling bit is 0, and makes the length of transmission block become the integral multiple of C.
The code block segmentation algorithm can be expressed as:
(1) code block number C:
(2) the bit number X of each code block:
As A＜40 and use Turbo coding, then X=40; Otherwise
(3) filling bit number Y:Y=C*X-A.
Filling bit is inserted in the front end of transmission block, and is 0.
In addition, in Fig. 1, also need to carry out the equilibrium of radio frames size.If when the length of a TT1 is 20ms, 40ms or 80ms, the corresponding codes bit need be sent on mean allocation to 2,4 or 8 radio frames.The size equilibrium is by degree the bit sequence of importing to be carried out suitable filling, guarantees that it carries out according to following rule through the evenly segmentation of output after filling:
(1) filling bit is placed on the end of input bit sequence;
(2) filling bit can be 0 or 1;
(3) length of establishing the input bit sequence is E, need all be assigned on F the radio frames and transmit, and N is the bit number that is assigned to after the size equilibrium on each radio frames, and then the length T of filling bit can be tried to achieve by following formula:
T＝F＊N-E
It should be noted that, Fig. 1 is the coding and the multiplex process of common transport channel, continuous evolution along with standard, other channels that are different from common transport channel have been introduced, as high speed descending sharing channel (HS-DSCH), enhancing special uplink channel (E-DCH), High-Speed Shared Control Channel (HS-SCCH) and high-speed shared information channel (HS-SICH) or the like, its code multiplexing process and Fig. 1 may be not quite similar, but its code block segmentation module is identical, the code block segmentation algorithm of using is identical with top narration, also needs to insert filling bit.
As mentioned above, according to existing protocol, code block segmentation in the physical layer encodes multiplex process of 3-G (Generation Three mobile communication system) standard and radio frames size equilibrium treatment unit may need to insert filling bit.And the filling bit that inserts or be fixed as 0 or is 0 or 1 random bit, and it doesn't matter with the real transmission block bit that needs transmission, causes the wasting of resources, reduced system spectral efficiency.Receiving terminal abandons filling bit, can not be used for improving system gain, also is unfavorable for the raising of transmission performance; And in fact the radio frames size of receiving terminal goes equilibrium treatment to carry out before channel-decoding, what be input to promptly that the radio frames size goes equilibrium treatment generally is soft information bit, if the filling bit that radio frames size equilibrium treatment unit inserts is not a random bit, but with the peculiar certain relation of importing of encoding ratio,, then when receiving, just can utilize to merge gain raising transmission performance as filling bit as several coded-bits; Though and the merging of receiving terminal code block occurs in after the channel-decoding, what carry out code block merging processing is not soft information bit, therefore in the time of can not going equilibrium treatment as above-mentioned radio frames size soft information bit is merged, but can not be fixed as 0 by the filling bit by with code block segmentation the time yet, but the bit information that the transmission block bit of being arranged to and importing has certain relation then can utilize this relation to improve transmission performance when receiving.In sum, how effectively utilizing above-mentioned filling bit, improve the transmission performance of system, is the problem that the present invention need solve.
