The technical field to which the invention relates

The present invention relates generally to method of reception and transmission in the communication system and, more specifically, to a method and apparatus for encoding managing information and transmission and reception of the encoded control information.

Description of the prior art

Broadcast communication services entered in the real era of digital technologies, the formation of a multitude of channels, broadband and high quality. Emerged recently, the prevalence of high-definition digital television (TV) and growth of number of subscribers of cable TV broadcasting has increased the widespread use of various devices of digital broadcasting using wired/wireless networks. Diagram of transmission, suitable for broadcast, and efficient encoding, transmission and reception of the management information required to receive broadcast data are important for providing reliable services digital broadcasting.

A typical example of a transmission scheme that is appropriate for the broadband may include multiplexing orthogonal frequency division multiplexing (OFDM). OFDM at which data is being transmitted using a number of carrier is a type of modulation many carriers (MSM), which converts the serial input character stream in parallel streams of characters and modulates every parallel thread characters multiple orthogonal sub-carriers, i.e. multiple channels demodulation, before sending.

Figure 1 illustrates the frame, which includes the control information in the famous system of communication.

According to figure 1, frame 101 includes the section 102 of the preamble, which includes characters 104, ..., 105 preamble and section 103 of the character data, which includes characters 106, ..., 107. Section 102 of the preamble usually used in the receiver for entry in the time of Yu and frequency synchronization, synchronization for the frame, etc. For these and other reasons transmitter communication system transmits section 102 of the preamble before sending the section 103 of data symbols.

However, depending on the communication system, the preamble may also be used to transfer the signal information as managing information that is transmitted and received between transmitter and receiver.

Figure 2 illustrates the configuration of the OFDM symbol, which transfers the preamble, in the famous system of communication. For ease of explanation OFDM symbol with the preamble, shown in figure 2, means OFDM symbol, to move the preamble. OFDM symbol with the preamble referred to here as “the OFDM symbol.

According to figure 2, OFDM symbol 201 includes the header 203, which is allocated to the multitude of sub-carriers, and block 205 coded alarm (referred to hereinafter as the “encrypted block”). In the block 205 coded alarm signaling information is allocated to the remaining that were not allocated to title, i.e. N

L1_Cells presented indices from 1 to N

L1_Cells .

Title 203 can be used to enter the synchronization of the receiver, and may include additional information, such as modulation scheme and code speed for the coded block 205. Here it should be noted that other supporting OFDM symbol 201, which additionally allocated for the characteristics of the pilot signal, etc. are omitted for convenience in describing.

Assuming that the preamble 102 embodied as OFDM symbol 201, sink is in sync across the frame header-based 203 preamble, receives control information, such as a transfer method characters 103 data and frame length of the encoded block 205 signal information and then retrieves the data from the data symbols 106, ..., 107.

Figure 3 illustrates the process of encoding and transmitting control data in a known system of communication.

According to figure 3, the transmitter generates a coded block from the signal of the information provided as control information through the use of encryption technology, based on proper code with error correction, and then allocates N

L1_Cells carriers are available for transmission of the signaling information. More specifically, if given the signal information to be passed, the encoder 301 straight forward error correction (FEC) generates a coded block by encoding the signal information according to a predefined encoding scheme. Modulator 303 forms the symbol modulation through modulation formed the coded block according to a predefined schema modulation. After that, the tool 305 display on supporting shows the symbol modulation N

L1_Cells carriers are available for transfer symbol modulation and the 307 insert header forms the OFDM symbol, as illustrated in figure 2, by joining title to such symbol modulation.

As described above, in the famous system of coded communication unit is formed of the signal information is transferred in OFDM symbol. Although for convenience, it was described that one coded unit is formed of the signal information is transferred in one OFDM symbol, alarm information can also be conveyed in more than one OFDM symbol. In this case, the communication system should segment the signal information on many coded blocks and send out multiple coded blocks in a number of OFDM symbol, which requires effective segmentation scheme, coding scheme and the scheme for transmitting and receiving.

A detailed description of the invention

Below with reference to the attached drawings will detail the various embodiments of the present invention. In the following description, detailed disclosure of known functions and configurations involved here omitted for clarity and conciseness.

The present invention provides a method and apparatus for encoding the signal information and/or control information between the transmitter and the receiver, the transmission and reception of the coded information in the communication system. Communication system, disclosed in this description includes the systems of wired and wireless communications, providing services of digital broadcasting and various communication services.

According to the variant of the implementation of the present invention, the transmitter segments signal information blocks depending on the size of the signal information, encodes blocks and passes the encoded blocks in OFDM symbol. Units include the same number of bits.

During the encoding process transmitter attaches bits to fill the signal information. The number of bits fill determined depending on the number of blocks received as a result of segmentation.

If the size of the signal information is large, for example, if the size of the signal information exceeds the predefined in the system size, the signal information bins on multiple blocks.

For example, suppose that the system, as shown in figure 3, the length of the encoded block, encoded FEC encoder 301, represented as N

L1 , and the order modulation presented as η

MOD , if Equation (1), the following is not successful, the system will not be able to send coded block signalling information in one OFDM symbol.

In Equation (1) order modulation η

MOD has a value of 1, 2, 4 and 6 binary phase keying (BPSK), quadrature phase keying (QPSK), 16-positional quadrature amplitude modulation (16-QAM) and 64-QAM, respectively.

Because the signaling information may sometimes not be transmitted in a single symbol, due to the condition of the system, signaling information is segmented. An example of segmentation process and the process of coding for the signal information is described in detail below.

In Equation (2) N L1_FEC_Block denotes the number of coded blocks required for the segmentation of the signalling information on the many block and transferring them, K L1__pad represents the length of the signal information prior to joining bits filling, and N Li_max_per_symbol indicates the reference value used for the segmentation of the signal information.

Transmitter segments signal information of length K L1__pad N L1_FEC_Block coded blocks. When K L1_ex_pad cannot be divided into N L1_FEC_Block , transmitter attaches bits to fill the signal information to determine the number N L1_FEC_Block coded blocks, received in the result of segmentation. In the General case, the amount of bits of filling is set to zero (0). The number of K L1_PADDING consolidated bits fill determined using Equation (3).

In Equation (3), if K

L1_ex_pad can be divided into N

L1_FEC_Block , the number K

L1_PADDING bits fill connected to the signal information is zero (0), otherwise, K

L1_PADDING has a nonzero value.

Therefore, if K

L1_PADDING has a nonzero value, signaling information of length K

L1 is formed through joining of K

L1_PADDING bits fill the signal data of length K

L1_ex_pad . Length K

L1 signal information with attached bits filling is computed using Equation (4).

Then, the signal information of length K

L1 segment on the N

L1_FEC_Block blocks. In this case, the signal information of length K

L1 is segmented on the N

L1_FEC_Block blocks, each of which has a length K

sig , which is determined using Equation (5).

The transmitter generates bits control parity through an independent encode each of the blocks of length K

sig segmented signal information, using the methodology developed by the FEC, and generates a coded block containing the bits parity each block segmented signal information. For example, a widely known encoding scheme with the concatenation code Bose (Bose), (Chaudhuri), (Hocquenghem) (BCH) and the code of low-density parity checking (LDPC) can be used as a method of FEC.

The encoding scheme with the concatenation of the transmitter first applies the BCH coding technique to each of the blocks segmented signal information, and then applies LDPC coding technique to each of the BCH-coded blocks. For convenience, it is assumed that the code BCH has a length information equal to K

bch , and length, parity, equal to N

bch_parity and LDPC code is code length (i.e. the number of bits in a code word)equal to N

LDPC , and code speed equal to R

LDPC .

If K

sig each block segmented signal information less than K

bch , you need the appropriate the reduction method for reduction ( K

bch - K

sig ) bits. The method of filling with zeros is usually used as a method of reducing. Therefore, if the bits corresponding to the zeroing, are not considered, BCH-coded blocks correspond to blocks of length K

sig segmented signal information, each of which is attached bits parity length N

bch_parity .

The transmitter uses LDPC coding technique with the reduction/exception to the units of length K

sig segmented signal information and attached bits parity length N

bch_parity . When given K

sig and η

MOD , the number N

punc (hereinafter referred to as “the number of permanently excluded bits”) bits parity LDPC be excluded, is calculated through the following four stages.

Step 1) the Transmitter is LDPC coding and then calculates the number N

punc_temp (hereinafter referred to as “number temporarily excluded bits”) bits parity to be temporarily exclude each coded block, according to Equation (6)below.

In Equation (6) _ denotes the greatest integer less than or equal to x , K

bch indicates the length of the information information word encoded, when the blocks are segmented signal information subject to encoding BCH, and K

sig indicates the length of each block, which included bits fill segmented signal information.

Step 2) Transmitter calculates temporary length N

L1_temp (hereinafter referred to as “the number of temporary bits of the code word”) coded blocks segmented signal information, using Equation (7)below, where R

LDPC code indicates the speed of LDPC code.

Step 3) Transmitter calculates the actual length N

L1 (hereinafter referred to as “final number of bits of the code word”) coded blocks the signal information, using the number of temporary bits of code word coded blocks segmented signal information, in accordance with Equation (8)below.

In Equation (8) L 1 _TI_MODE is a mode of a technique of time the interleave for coded blocks segmented signal information, and this information is included in the header 203, illustrated in figure 2 L 1 _TI_MODE = 00 indicates the absence of the temporal application of the th interleave, L 1 _TI_MODE = 01 indicates that N

L1_FEC_Block coded blocks received signal segmentation of the information transmitted in N

L1_FEC_Block OFDM symbols through the application time of alternations.

And L 1 _TI_MODE = 10 and 11 indicates that N

L1_FEC_Block coded blocks received signal segmentation of the information transmitted in N

L1_TI_Depth OFDM symbols through the application time of alternations. L 1 _TI_Depth in N

L1_TI_Depth indicates the depth of the temporal go interleave used to transfer OFDM symbol, and the value of N

L1_TI_Depth could properly be set according to the regime L 1 _TI_MODE defined in the system.

Step 4) Transmitter specifies the number of bits-parity LDPC be excluded, i.e. number N

punc permanently excluded bits, using Equation (9)below.

In the above process of segmentation and coding for the signal information, N

L1_max_per_Symbol in Equation (2) in the General case, is set in K

bch . Accordingly, if the length K

L1_ex_pad the signal information is variable and has a very broad range, the maximum value of K

sig in Equation (5) can be equal to K

bch and the minimum value N

punc_temp becomes 0 according to Equation (6).

If N

L1_max_per_Symbol , the reference value used for the segmentation of the signal information, which is described in Equation (2), is too high, i.e. if the length K

bch code word BCH code is too large, then the number N

L1 final bits of code word or the length of each code word segmented signal information can also be very large, resulting in a N

L1 /η MOD , which is determined by dividing the amount of the final bits of the code word is on the order of modulation can be junk degree greater than the number N

L1_Cells carriers that can be used for transmission of the signaling information in OFDM symbols.

As an example, we will consider a system that has the parameters shown in table 1.

Table 1

Parameters OFDM modulation

Parameters of the BCH

Parameters LDPC

N

L1_Cells = 2808 η MOD = 4

K

LDPC = 16200

R

LDPC = 4/9

Assuming that the system K

L1_ex_pad = 10000 when N

L1_max_per_Symbol made the same as the K

bch , it's easy to understand that in a system using parameters in table 1, signaling information in length, for example, 10000 bits can be segmented into two unit length 5000 bits each without the use of methods of TB profile of alternations, using Equations (2)-(9), and length N

L1 each coded block segmented the signal information is equal 11744 bits.

Thus, in this case, since N

L1 /η MOD = 2936 more than N

L1_Cells (=2808) in the system, each coded block segmented the signal information is not displayed in one OFDM symbol.

In the General case, because one coded block is in one OFDM symbol in the system, where the provisional alternation is not applicable, N

L1_max_per_Symbol must be set lower than K

bch in the example above system.

However, if N

L1_max_per_Symbol is set too small, each the encoded block segmented signal information can be displayed on one OFDM symbol, but require a large number of OFDM symbol, and some of the carriers are included in one OFDM symbol, can be irrationally used. If N

L1_max_per_Symbol established, for example, in 1000 bits in the system of the alarm information can be segmented into 10 units and length N

L1 coded blocks equal 2960 bits. In addition, since N

L1 /η MOD = 740, 740 carriers are allocated to one OFDM symbol for each transfer the coded block segmented signal information, and although the remaining (2808-740=2068) sub-carriers are not allocated for the transmission of the coded blocks, the total number of 10 OFDM symbol you want to transfer the entire signal information. Unselected or unused 2068 carriers are unused even for K

L1_ex_pad .

Therefore, the reference value of N

L1_max_per_Symbol (hereinafter referred to as “reference value segmentation signal information”) for the segmentation of the signalling information must be properly installed in accordance with the conditions to effectively segment and pass this signal information while minimizing the number of irrationally used carriers and the number of required OFDM symbol.

Optimal reference value segmentation for the signal information, the proposed way of the implementation of the present invention for the segmentation of the signaling information and the transfer of segmented signalling information in the OFDM symbol is described below.

Optimal reference value segmentation for signalling information in accordance with the embodiment of the present invention will meet at least one of the following two conditions.

If the reference value of N

L1_max_per_Symbol segmentation for the signal information increases, the number of N

L1_FEC_Block coded blocks of Equation (2) aims to reduce or remains the same. Therefore, to satisfy the Condition 2) the reference value of N

L1_max_per_Symbol segmentation for the signal information should be set as large as possible.

However, because the increase of the reference value N

L1_max_per_Symbol segmentation for the signal information increases the maximum number of K

sig by the Equation (5), the minimum value of N

punc_temp by the Equation (6) is reduced. As a result, since the length N

L1 each coded unit seeks to increase the overall Equation (7) and (8), N

L1 /η MOD that is determined based on the order modulation, also strives to increase the

Therefore, the embodiment of the present invention calculate the maximum reference value N

L1_max_per_Symbol segmentation for the signal information, which satisfies the Equation (1).

Here it should be noted that, because of the length N

L1 coded blocks is influenced by order modulation η MOD and the number N

L1_FEC_Block coded blocks in Equation (8)if the order modulation η MOD and/or the number N

L1_FEC_Block coded blocks are changed, the maximum value of the reference values N

L1_max_per_Symbol segmentation for the signal information, satisfying the Equation (1)is also changed.

For example, assuming that the system using the parameters in Table 1, segmenting and encodes the specified signal information, using all of the Equation (2)Equation (9)if the number N

L1_FEC_Block coded blocks is assumed to be 1, then the maximum value of the reference values N

L1_max_per_Symbol segmentation for the signal information, satisfying the Equation (1)is calculated equal 4773 bits. However, if the number N

L1_FEC_Block coded blocks is assumed to be 5, the maximum value of the reference values N

L1_max_per_Symbol segmentation for the signal information, satisfying the Equation (1)is calculated equal 4759 bits.

Therefore, to satisfy the Condition 1 and Condition 2) regardless of the order modulation η MOD or the number N

L1_FEC_Block coded blocks, require a special restriction when defining the reference value N

L1_max_per_Symbol segmentation for the signal information.

Regards the above-mentioned limitations, the embodiment of the present invention determine the maximum value of the quantity N

L1_FEC_Block coded blocks and depth N

L1_TI_Depth of Equation (8) as the maximum number N

L1_FEC_Block_max coded blocks, whereas the temporal R e alternation, and offer criteria for selection of the reference value N

L1_max_per_Symbol segmentation for the signal information.

Selection criteria

The reference value of N

L1_max_per_Symbol segmentation for the signal information is selected as the lowest value among maximum length values K

i signalling information to satisfy the following Equation (10) for i (where i = 1, 2, ..., N

L1_FEC_Block_max ).

In Equation (10) N

L1_Cells denotes the number of sub-carriers, or cells that can be used to transfer the signal information, and N

L1 ( K

i ) the length of the encoded blocks the signal information when the length of the signal information is represented as K

i , for i = N

L1_FEC_Block .

An example of a definition of the reference value N

L1_max_per_Symbol segmentation for the signal information depending on the selection criteria under this the invention will be described below.

Assuming that the system using the parameters in Table 1, segmenting and encodes the signal information, using Equation (2)Is the Equation (9), and that the maximum number N

L1_FEC_Block_max coded blocks is set to 8 as additional conditions, Equation (10) can be rewritten as shown in Equation (11).

Then, based on the selection criteria, the reference value of N

L1_max_per_Symbol segmentation for the signal information is selected as the lowest value among maximum values of K

i satisfying the Equation (11), for i (where i= 1, 2, ..., 8). If the maximum values of K

i , satisfying the Equation (11), represented as K

i,max for each i , they have the following form

K

1,max = K

2,max = K

3,max = K

4,max = K

6,max = 4773,

K

5,max = K

7,max = K

8,max = 4759.

Therefore, the reference value of N

L1_max_per_Symbol segmentation for the signal information is set to 4759, that is the lowest value among maximum values of K

i,max according to the selection criteria in accordance with the embodiment of the present invention.

Figure 4 is a block diagram of the sequence of operations of the encoding process control information in accordance with the method of implementation of the present invention.

According to figure 4, on the stage 401 transmitter is a segmentation of the signalling information on many blocks according to the size of the signal information. Operation segmentation is performed based on the reference value N

L1_max_per_Symbol segmentation for the signal information, which is obtained depending on the selection criteria.

At the stage of 402 transmitter is zero-fill for encoding VSN in respect of each of coded blocks segmented signal information. At the stage of 403 transmitter performs encoding VSN in respect of the signal information, which is attached bits filling. Zero-fill for encoding VSN is different from writing zeros to segment the signalling information in Equation (4). At the stage of 404 transmitter is LDPC coding in relation to the BCH-coded blocks segmented signal information. At the stage of 405 transmitter is an exception in respect of LDPC coded blocks according to the number of excluded bits. In accordance with the embodiment of the present invention, the way to determine the number of excluded bits may include the procedures 1)-4). The results obtained ultimately on the implementation of the above processes, meet coded blocks segmented signal information.

Figure 5 illustrates the way of segmentation, encode and transmit signal information in accordance with the method of implementation of the present invention.

According to figure 5, signal information for the current frame is determined on the stage 501, and the transmitter on stage 502 determines the number of coded blocks, with the help of which he will bring the signal information, using Equation (2). More specifically, the transmitter uses the reference value of N

L1_max_per_Symbol segmentation for the signal information, obtained on the basis of the selection criteria.

At the stage of 503 transmitter calculates the number of bits fill required for the segmentation of the signal information, according to Equation (3) and attaches bits to fill the signal information if necessary. At the stage of 504 transmitter segments signal information on the blocks of the same size, the number of which corresponds to the number of coded blocks, which is determined according to Equation (5). The size of the signal information, segmented on stage 504 does not exceed the reference value of N

L1_max_per_Symbol segmentation for the signal information received according to the selection criteria.

After this, at the stage of 505 transmitter calculates the number of bits-parity, which must be subjected to the exclusion, for coded blocks, using Equations (6)-(9). At the stage of 506 transmitter generates a coded blocks to the number determined at the stage of 502, through the implementation of FEC coding against the signalling information, segmented on stage 504. At the stage of 507 transmitter eliminates bits parity in the number defined at the stage of 505, for each of the coded blocks, formed at the stage of 506. At the stage of 508 transmitter transmits the final encoded blocks defined at the stage of 507, starts processing the next frame and then repeats the steps 501-507 for the next frame.

Figure 6 illustrates a way of reception of the signal information in accordance with the method of implementation of the present invention.

According to 6, at the stage of 601 receiver receives the number of bits the signaling information transmitted in the current frame. The number of bits the signaling information can be obtained by receiving and decoding the header 203 OFDM symbol. Because the number of bits transmitted signal information can be obtained from the header 203, the receiver can calculate and obtain the number of K

L1 bits the signaling information, including bits of filling, which were attached during segmentation signal information. As another example, you can also get the number of K

L1 bits the signaling information, which inserted bits filling, directly from the header 203 OFDM symbol.

At the stage of 602 receiver calculates the number of coded blocks, with the help of which the signal is transmitted information, using Equation (12)below.

It should be noted that the reference value of N

L1_max_per_Symbol segmentation for the signal information is set to the value obtained on the basis of the selection criteria.

At the stage of 603 receiver computes the length K

sig (number of bits) of the respective coded blocks, received as a result of the segmentation of the signal information, in accordance with Equation (5)given above.

At the stage of 604 transmitter calculates the number of bits-parity, in respect of which must be fulfilled exception, for each of the coded block. The method of calculating the number of excluded bits identical to the method described using Equation (6)Equation (9). At the stage of 605 receiver restores adopted signal information by decoding each of coded blocks, number of which is determined at the stage of 602, using the calculated number of excluded bits. At the stage of 606 receiver starts processing the next frame and repeat steps 601-605.

Fig.7 illustrates the transmitter under variant of the implementation of the present invention. More specifically, Fig.7 illustrates transmitter for transmitting information alarm physical level (L1) as control information.

According Fig.7, transmitter 700 includes buffer 701 data transmission, a means 702 planning tool 703 formation of a management information tool 704 calculation of control parameters, the controller 705, FEC encoder 706 and module 707 transfer. Because the control information represents the signal information, the tool 703 formation of management information forms the signal information and module 707 transfer signal information.

When the communication system provides broadcasting service, in the buffer 701 data transfer buffered data services that will be delivered in a variety of channels broadcast services, and when the communication system offers the service of communication in the buffer 701 data transfer buffering data services provided in this service connection.

Tool 702 planning planning, through reception of information as regards data buffered in the buffer 701 data transmission. Operation planning includes the definition of the configuration of frame through the inclusion of OFDM symbol and character data to be transmitted, in particular frame or every frame. Alarm information is transmitted in the OFDM symbol. Planning results are entered in the tool 703 formation of the control information.

Tool 703 formation of management information generates specific values of the signal fields, of which could be identified configuration frame. Tool 704 calculation of control parameters, the receiving these field values calculates the number N

L1_FEC_Block coded blocks segmented signal information, the number of bits of padding for segmentation, the number of bits segmented signal information and the number of bits-parity, in respect of which must be fulfilled the exception, as control parameters for transmission of the signaling information, according to the method described in combination with 5.

The calculated control parameters are entered into the controller 705.
