Abstract

A method and technique are provided for efficiently acknowledging transmitted information in a system that employs variable rate data transmission, and skips data block sequence numbers depending on the transmission rate used. An RBB field in an ACK/NACK message includes a starting sequence number, an indication of a sequence number step, and a bitmap. The starting sequence number indicates a first block in a series or sequence of transmitted blocks that are being acknowledged via the ACK/NACK message. The sequence number step indicates a minimum difference between sequence numbers of blocks in the sequence. Where the sequence is ordered, the sequence number step is a difference between the sequence numbers of adjacent or consecutive blocks in the series. The bitmap is configured so that each bit in the bitmap represents an acknowledgment of one of blocks in the series. The RBB field can also include multiple starting sequence numbers, and both a sequence number step and a length for each starting sequence number. Each set of starting sequence number, sequence number step and length indicates a subseries or subsequence of the series of transmitted blocks that is being acknowledged via the ACK/NACK message. The starting sequence number indicates a sequence number of a first block in the subsequence, the length indicates how many blocks are in the subsequence, and the sequence number step indicates a difference between sequence numbers of adjacent blocks in the subsequence.

Description

V. Description of the invention (1) 1. The scope of the invention, tr = iu.s.c. §119, U.S. Patent No. 60 / 110,444 filed on November 27, 1998. Mingi inventions are usually related to error handling in the field of communication systems, and more specifically, Hu is about errors by using automatic repeat: ARQ and variable rate transmission technology used in digital communication systems. 2. Variable rate transmission of background information in wireless systems can be achieved by using several methods. For example, in a CDMA (Code Division Multiple Access) system, the information transmission rate is used for transmission expansion. One of the factors-function changes. In a TDMA (time-division multiple access) system, variable rate transmission is usually achieved by using time slots. In a TDMA system, the data transmission rate is also changed by one of the modulation and coding functions used to map data bits to channel bits / symbols. ^ In addition to the variable number of time slots, EDGE (Overall Progress to Improve Data Rate) is a systematic example using different modulation and coding methods to achieve different transfer rates of user data. The non-modulation and coding methods used in the EDGE system MCS-i to chaos 3_6 have various payload sizes, which are different from the example of the increment of 25 octets shown in Fig. 1.囷 2 Excerpt from different area * size 'Margin, and the payload size of MCS-1 to MCS-6 with different modulation and coding methods. As shown in Figure 2, the modulation method includes PSK (Phase Shift Keying) and GMSK (Ifjs Minimum Offset Keying). The block encoding method that determines the payload of a block is in U.S. Patent No. 09/120, 163 ’Name“ Method and Apparatus for

Ir '441199 Five' Invention note (2)

Minimizing Overhead in a Communication SystenT is disclosed, which is listed here for reference only. The basic principle of the coding method is described in Figure 3. As shown in FIG. 3, 'block numbers (SNs) can be an integer multiple of the number of modulation and coding methods currently used, or can be separated by a step of the same identification code size. In the case where the current modulation and coding method is MCS-6, consecutive blocks can be assigned serial numbers 6, 12, and 18. The round-trip time (RTT) shown in Figure 3 is related to the amount of elapsed time between transmitting one or more blocks and receiving their acknowledgement. As shown in Figure 3, —The payload size of a block of the current modulation and coding method can be defined as many octets, and these octets are equal to the identification code of the current modulation and coding method and A product of one block size increment between encoding methods. For example, the block payload size of MCS: 6 modulation and coding method can be defined as (6) (25) octets and = 150 octets and size. When a data block is retransmitted at a rate lower than the initial transmission of the data block, the initially transmitted data can be re-segmented into blocks of different sizes, or different blocks with different payload sizes, and different Big Blocks = This will renumber them. For example, as shown in FIG. 3, block 12 containing MCS-6 method with 50 octets-payload can be re-segmented into two blocks 9 and 12, each containing 75 octets. The load is then retransmitted according to the MCS_3 method. -This procedure can be repeated as needed or appropriate. For example, as shown in Figure 3, if the retransmitted block 9 is not received correctly, then it can be re-segmented into 3 blocks 7, 8 and 9, each according to Mark Bu! Method can contain 25 eights

V. Description of the invention (3) Where ^ 's have payload' and retransmit with new blocks 7, 8 and 9. By using the technique described in Figure 3, the data can be retransmitted with appropriate time-to-transmission / red-shifting and encoding. For example, the data can be retransmitted with a modulation and coding method that is more logical and better than the method used for the initial or previous data transmission. Pray for time zone: Material :! The block can also be re-segmented into a smaller number for retransmission and needs =. As shown in Figure 4, in the case of two blocks 4 and 6 of the Mcs-2 method, a new transmission is required in the case of a new transmission. In terms of transmission time, MCS_4 method 2 is the most ideal or more appropriate. The two blocks 4 and 6 of MCS-2 method are combined to form a single block 6 of MCS-4 method, and therefore can be retransmitted. The MCS-4 method block 6 payload can be formed by linking the MCS_2 method blocks 4 and 6 payloads. Note that when the optimal initial encoding method is changed from MCS-2 to MCS-4 and the two blocks are combined, the last connected block is identified by the second block number 6. Alternatively, when a contiguous block is combined, the 'last combined block can be identified by the serial number of any suitable block in succession. For example, 'the combined block can be identified by the serial number of the first consecutive block or the serial number of the command block. As shown in FIG. 5, the ACK / NACK (valid acknowledge / negative disc acknowledge) message includes a received block dot map (RBB) field format 506, and the received block dot map block format has a start sequence number (SSN ) 502 and the point immediately after it Figure 5 0 4 = Point Figure 5 0 4 contains one of every possible serial number of the continuous data block starting with a block to confirm that the serial number of this block has the same as SSN 5 0 2 The value of the same sequence number. Therefore, when using this technique, a receiver must be able to validly or negatively acknowledge all serial numbers represented in an RBB bit with format 506 'and

V. Description of the invention (4) Regardless of whether all serial numbers are actually used to transmit data blocks. FIG. 6 shows an RBB field 606 with format 506. A single bit in dot map 506 can be used to identify a block. The block numbers of the blocks confirmed in dot map 5 06 correspond to the bits in dot map 5 06 in order from left to right and top to bottom: dot map 5 6 includes One bit for each possible sequence number between the start and end block numbers. In other words, the bits in the dot map represent or call out blocks with serial numbers' and the serial numbers are separated by a smallest step, regardless of whether a particular sequence of steps in the block is greater than the smallest step 'Therefore, the used and unused serial numbers can be represented or confirmed by the dot map 506. For example, as shown in Figure 6, when the RBB booth 606 is used to indicate that it is configured according to the MCS-3 method (so the number of these blocks in the 12 block sequence is separated by a step of 3) When confirming the state of a 12-block sequence, each third bit in the dot map 506 represents the 12-block sequence—the confirmation state of the block. As shown in Figure 6, the sequence starts with data block 5 (as represented by SSN 602), and includes the sequence numbers 15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, and 48. Block. As shown in FIG. 6, each block having a serial number of 15, 18, 30, and 39 is represented by a three-digit value having a value of 10 to indicate that the district Wei with a serial number of 15, 18, 30, and 39 has been denied Acknowledged (NACKed) and need to retransmit. However, the serial numbers of ^ are not 16, 17, 19, 20, 22, 23, 26, 26, 28, 29, 31, 32, 34, 35, 37, 38, 40, 41, 43, 44, 44, 46, 47. , 49 and 50 are also confirmed. Therefore, the entire (3) (12) = 36 bits in the point graph 604 is needed to represent a 12 block sequence configured according to the MCS-3 method.

Page 10 General, 4 4 1 1 9 9 V. Confirmation status of invention description (5). Other methods may be needed, even if there are more positions in the plot. For example, if a 12 block sequence is configured according to the MCS-6 method, a total of (6) (1 2) = 72 bits will need to be used in the dot map to confirm the 12 block sequence. In summary, the RBB format shown in FIG. 5 is a block that is not suitable for valid and negative confirmation transmission in a system using variable rate data transmission, and it will skip the area serial number, which is determined in the used Variable rate. For example, in the case of using MCS-6 method and establishing serial numbers of 12, 18, ···, 6 * N} with a continuous n blocks, the RBB format will require such continuation numbers μ, 2, 3, 4, 5. ··. 6 * Ν} each has a different disc recognition, even if only the serial numbers {6, 12, 18, _._ 6 * n} need to be considered. Therefore, when using a system that uses variable rate data transmission and decides on the used transmission rate to skip the block sequence number, the RBB format does not require a large load. Therefore, there is a need for an effective low-load method and technology for validly and negatively confirming a transmission block in a system that uses a variable-rate data transfer wheel and jumps depending on the transmission rate used Block number. SUMMARY OF THE INVENTION According to various specific embodiments of the present invention, a method and technology are provided in a system that can effectively confirm the transmitted information, and the system uses variable rate data transmission, and depending on the transmission rate used, Jump data block sequence number According to a specific embodiment of the present invention, the ACK / NACK load of a variable rate communication system is reduced by the denser RBB format, so it can be transmitted and evaluated in less time. This saves time and computing resources, and allows data to be retransmitted with minimal delay. in other words,

Fig. 11B shows a special example of an RBB shelf according to the RBB format shown in Fig. 11A. FIG. 12 is an RBB format of an RBB block displayed in a _ACK / NACK message according to a specific embodiment of the present invention. FIG. 13 shows an RBB format of an RBB field in an ACK / NACK message according to a specific embodiment of the present invention. Detailed description of the preferred embodiment According to a specific embodiment of the present invention, a single ACK / NACK message is a block for validly or negatively acknowledging multiple receptions. According to a first embodiment of the present invention, a single sequence number step (SNS) can be used. S N S defines a difference between contiguous numbers of a sequential block number. This concept is described, for example, in FIG. 7. As shown in FIG. 7, an RBB format 700 includes an SSN field 702, an SNS field 704, and a one-dot field 706. For example, the SNS can be an increment or a decrement * which determines whether the values in the sequence increase or decrease. FIG. 8 shows an RBB stop 800 with the format 700. SSN 80 2 is 15, SNS 804 is 3, and the bit system in dot map 806 indicates that those blocks have been successfully received, while those are unsuccessful. For example, point figure 806 can be configured, so the sequence is moved across from left to right and from top to bottom across point figure 806, so " 0 " means NACK, and " 1 " means ACK. With the appearance of this structure, the dot plot 806 indicates that the blocks with sequence numbers 15, 18, 30, and 39 are negatively acknowledged, and therefore have to be retransmitted, and have the sequence numbers 21, 24, 27, 33, 36, 42, 45, and 48. Blocks are effectively called.

Page 14 ^ 4 4 T 1 9 9_ V. Description of the invention (9) When 3 bits are used to represent SNS 804, there are only (3 + 12) = 15 bits (the 3 bits of SNS 804 and The 12 bits of point 806) need to be valid or negative in a series of blocks with sequence numbers 15, 18 '21' -24 '27, · 30 '33, 36, 39, 42, 45 and 48 Every block. In contrast, the 34 bits need to use the bit map 604 to confirm each block in the sequence {15, 18, 21, ... 48}. Reducing the number of bits that need to be valid or negative to confirm in a series of blocks can reduce load and increase efficiency. Although an example of an SNS with 3 bits is the technique described above, the technique described above confirms that any suitable number of bits can be selected to represent the SNS. As shown in the examples of Figs. 7 and 8, when an applicable method can clearly confirm that in the first block of the sequence, SSN 702 implies a negative confirmation of the corresponding block. For example, "in the case where the MCS-3 sequence (15, 18, 21, ... 45, 48) is to be confirmed", the first entry in the dot graph 806 will correspond to a block with SN = 18 instead of SN = 15. Of course, SSN 702 may know that it can effectively confirm the corresponding block. If a method including an SSN field can be used, it can be understood that the SSN is always 0 (zero). In this case, the SSN field 702 of the RBB format 700 can be omitted. According to a second specific embodiment of the present invention, blocks in a series of blocks having different sequence steps have valid or negative confirmation by using the same RBB block. In other words, a single RBB field can be used to identify all blocks in a sequence 'where the sequence includes subsequent blocks, and different subsequent blocks have different sequence steps.

Page 15 A41 1 9 9 V. Description of the invention (10) According to the second specific embodiment of the present invention, FIG. 9 shows an example of a KβB block format 900 representing a series of blocks, where the sequence includes subsequent blocks, etc. Each of the blocks has a different sequence number. As shown in Figure 9, the 'rbb block format 900 also includes a step flag 902 °. Each bit in the step flag block 902 represents a different possibility. Step number 'and a flag function that acts as that step. The step flag field 9 02 can be configured, so when a bit in the step flag field 902 is "1", the corresponding flag can be set, and when the bit is " 〇 ", the corresponding Flag cannot be set. Each subsequent block in the sequence is made by using a pair of 904 in the first sequence-block start number (SSN) in the sequence, many subsequent blocks L, and the one in step flag field 902. Wait for one of the flags to define it. For example, the ιϊββ block format can be configured, so a first set flag in step flag bit 902 corresponds to a first pair of 9 04, and a second set flag in step flag block 90 2 matches a second pair. 904 and so on. For example, when moving from set to right across the set field 902, the first " set flag will be the first flag. For example, when moving from top to bottom via a series of pairs 904 in RBB stop 900, the first pair "9 0 4" is the first pair 9 04. For example, the first pair 9 0 4 may be the pair 904 including the SSN field 906 and the length field 908 as shown in FIG. 9. Therefore, the 'first setting flag indicates a subsequent one corresponding to the first pair 9 04 and the first setting flag. Step of block numbering. Similarly, the second setting flag indicates the sequence number of the subsequent block corresponding to the second pair of 904, and so on. The SSN fields 9 0 6 and 9 0 for 90 4 contain different SSNs from subsequent ones, and

Page 16 V. Description of the invention (11) Each of the length fields 908 and 9 12 contains a number indicating a corresponding subsequent length. For example, the subsequent length can be many subsequent blocks. All subsequent blocks can be confirmed by using the bits in point 9 1 4. Figure 10 shows an example of an RBB stop 1000 with format 900. As shown in FIG. 10, the step flag stop 902 indicates that the sequence steps appear in a series of blocks indicated by field 1000. The step flag field 902 indicates ascending power from left to right. For example, the flags corresponding to the steps or the step values 1, 3, and 6 are set equal to " 1 ", indicating that the sequence contains subsequent blocks with steps 1, 3, and 6. The pair of steps corresponding to step 004 appears in the sequence and is arranged in descending order in the field 10000 in descending order. For example, the highest pair 1004 of an SSN 1006 and an L 1008 corresponds to a step with a value of 6. The value 24 of the SSN 1 0 0 6 indicates that it has a serial number of 24 in the subsequent first block. The value 12 of the length L 1008 indicates that it is followed by 12 blocks. Therefore, step 6 of the highest pair 1004 together with SSN 1006 and L 1008 represents or defines the subsequent blocks with the serial numbers 2 4, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, and 90. Similarly, the pair 1004 of SSN 1010 = 93, L 1012 = 7, and step 3 represent the subsequent blocks with the numbers 93, 96, 99, 102, 105, 108, and 111. SSN 1016 = 112, pair 1 004 with L 1018 = 5, and step 1 represent subsequent blocks with sequence numbers 11 2, 11 3, 1 1 4, 1, 1 5 and 116. The one-point diagram 1 0 1 4 indicates that those blocks in the sequence are valid confirmations, and those negative confirmations. For example, point figure 1 0 1 4 can be configured, so the bit value of "1" indicates that a corresponding block is a valid confirmation, and the 0 bit value indicates

Page 17 ^ / 14119 9 V. Description of the invention (12) A corresponding block is negatively confirmed. Subsequent blocks represented in the top-to-bottom order of the pairs 104 are represented in the order 1014 in left-to-right and top-to-bottom order. In addition, the block numbers in the following sections are shown in ascending order from left to right and top to bottom at point 104. Therefore, as seen in FIG. 10, the bit system at point 1014 indicates that the blocks with sequence numbers 24, 48, 54, 66, 84, 93, 96, 108, 112, and 115 are negatively acknowledged and need to be retransmitted ^ The steps indicated in the flag field 902 and the subsequent steps indicated by the pairs 904 can be ordered in any suitable way. For example, as for the selection of the ranking as described above, the step flag field 902 indicates the steps in descending order from left to right, and the pairs 904 may occur or correspond to the order from bottom to top instead of top to bottom. For example, the selection of the flag field 902 contains the actual step value instead of a single bit flag. In this case, the value of each step corresponds to that of the 904 series which defines the subsequent zone wash. Step values can be sorted in stop 902, so a first step value in bad position 902 matches a first pair 904, and can help define a first subsequent block in the sequence, a The second step value corresponds to a second pair 904 'and can help define a second subsequent block and the like. In addition,-as in the selection of the step value aggregation in column 9 02, each step value of the step values may be a pair of corresponding SNS and length values. For example, as shown in FIG. 11A, according to the present invention, In a specific embodiment, the RBB formula 1100 includes three groups of 1104, each of which defines a sequential arrangement of a series of regional souls. Each group of 3 includes a sequence number step SNS, a subsequent block number (for example, an SSN), and a subsequent length i ^ RBB grid.

Page 18 4 4 1 19 9 V. Explanation of the invention (13) The formula 1100 may also include a number N of the number Π06. The number n indicates how many successive arrangements are a series of blocks of confirmation and / or representation. . For example, the selection of booths 1106 is 'one every three' and 1104 also includes a single bit e to indicate whether the dotmap will follow immediately. Therefore, one of the field 丨 〇 6 and the bit field E can be omitted. Other appropriate mechanisms may be provided to represent a location of the dotmap in RBB format 1100. FIG. 11B shows an example of an RBB field 1102 according to the RBB format 1100, which includes two or three components 1104. The first three components 1104 indicate that the definition starts with SN = 1, has SNS = 4, and has a length of 4 (that is, it has 4 serial numbers or blocks subsequently). The bit value e = 〇 indicates that the first and third components 1 1 0 4 are not followed by a dot. The second three components represent sequential definitions that begin with SN = 14, have SNS = 2, and have a length of 4. The bit value E = 1 indicates that the dot map π 14 immediately follows the second and third components 11 04, and the dot map 1114 indicates that there are blocks that need to be retransmitted with continuation numbers 1, 8, U, 16 and 20. Alternatively, the dot map 1114 can be replaced with a list of block numbers that are sequentially arranged as defined by the three components 1104 that need to be retransmitted. For example, 'such as # this technique is applied to the RBB stop shown in FIG. 11B, then the list of sequence numbers will include 1, 8, U, 16 and 20. In the case where a larger number of blocks are identified in the RBB field and a lower percentage of retransmissions is required, this technique is more effective than making reading points 1 1 1 4. According to another embodiment of the present invention, an RBB format can include a serial number indicated by the Ming system, and its appearance can confirm the corresponding block. For example, "Fig. 1 > 1 is very clear and shows an RBB format 1200 similar to the RBB format 700" but also a private symbol

Page 19 Ιττ / 14 1 1 9 9 V. List of serial number fields 1208, 1210, and 1212 represented by the description of the invention (14), which contains serial numbers Snt, S & and SNk. Any suitable number of explicit number fields can be included, and the RBB format 1200 can optionally include a sequence number (SNQ) 1214, which indicates how many clearly indicated sequence numbers follow the dot plot 706. The confirmation can be known to be negative or valid, or it can be expressed in the -selective bit P / N 1216, and its value indicates whether the confirmation is negative or valid. According to another embodiment of the present invention, an RBB format includes parameters, which can clearly identify a series of serial numbers that are both valid or negative. For example, as shown in FIG. 13, an RBB format 130 similar to the format 700 also includes a set of parameters that define a series of serial numbers. For example, the group includes an SSN block 1308 containing a starting sequence number, an SNS field 1310 representing a sequential or subsequent sequence step, and a length field Len 1 31 2 indicating the sequence or subsequent sequence numbers. . Alternatively, the field Len 1312 may be included in the sequence number of a last block in the sequence ° The confirmation (valid or negative) of all blocks in the sequence may be understood or represented by a selectable bit P / N 1314, whose value indicates the It is confirmed whether it is 疋 or η irir liL ^ In addition to the specific embodiment shown in FIG. 7 ′, the techniques / instruments shown in FIGS. 2 and 13 can also be implemented in other specific embodiments of the present invention described above. For example, when the 〆 δ step is selected, when the technique described in Figs. 12 and 13 is used in the dot plot booth, the SSN and SNS columns 702 and 704 can be completely omitted. / Su Shun According to different embodiments of the present invention, the order in the κββ field can be changed, and the order of the number in the RBB stop can also be changed.

Page 20 rr-441 1 -9 9 V. Description of the invention (15) If ‘or, the bit in the field 1002 can represent the step of power reduction in the value across the bad bit 1002 from left to right. The serial number indicated in the dot chart can be reduced from left to right and / or from the lower power in each subsequent period. Β is used in the RBB field in a series of blocks and includes asynchronous scales. Each subsequently has a single step, and these can then be represented in the R B B booth in a different order as well. For example, these can then appear in ascending or descending order by steps or SSN (as represented by, for example, the information of the pair 1004 'and / or by the corresponding position in the plot point of the RBB field) . In addition, a sequence number or a subsequent last block number may be used instead of using a start number corresponding to the sequence or a subsequent first block number. In general, according to various embodiments of the present invention, the information contained in a field or sub-field within the RBB field format can be ordered in any suitable manner. The information in these or secondary fields can also be sorted in any suitable way. According to a specific embodiment of the present invention, the actual value of the replacement flag is stored in a RBB field, and the number of bits used to represent the value can be appropriately selected. For example, as for an SNS field that can store one of the start numbers of a block in a sequence or successively, the size of the SNS field, such as the number of bits used to indicate the value stored in the SNS field, may be appropriately selected. 'Minimum number' This minimum number is sufficient to indicate the maximum sequence number of a first-block in a sequence or succession. A specific embodiment according to the present invention " can indicate valid confirmation, and " factory can be used to indicate a negative confirmation instead of 1 " for negative confirmation and " Γ 'for the use of valid confirmation.

Page 21 V. Description of the invention (16) According to a specific embodiment of the present invention, one or more sequence steps indicated in the RBB field may indicate the size of the step, and the RBB block may include a separate representation of each step. Or may include a representation of applying all steps to indicate whether the corresponding step is a decrement or increment.
