Description

 Data transmission control method and device

 The present invention relates to the field of communications technologies, and in particular, to a data transmission control method and apparatus. Background technique

 In the existing LTE (Long Term Evolution) system (version 8 to version 11), in order to maintain downlink coverage of a cell, the base station needs to transmit a downlink dedicated control channel (PDCCH, physical downlink control channel) for a dedicated pilot ( CRS, Cell-specific Reference Signal (PBCH, Physical Broadcast CHannel) Synchronization signal (PSS (Primary Synchronization Signal) / SSS (Secondary Synchronization Signal)). The PBCH and PSS/SSS signals are transmitted in the middle of the system bandwidth 6 RB (Resource Block), and the PDCCH and CRS are transmitted in the whole system bandwidth. These cell-specific signals, especially the PDCCH and CRS signals transmitted over the full bandwidth, are one of the main difficulties in inter-cell interference coordination.

 In the process of implementing the present invention, the inventor has found that in order to better perform inter-cell interference coordination and minimize unnecessary resource overhead to better improve data transmission efficiency, the R12 version of LTE introduces a new carrier type. (New Carrier Type, NCT). On the NCT, the legacy PDCCH will be replaced by an enhanced PDCCH (ePDCCH). The CRS is no longer transmitted every subframe, but in a period of 5ms (5 subframes), and is transmitted in only one of the subframes per cycle. Therefore, compared with the conventional carrier, the resources available for transmitting user data in each RB resource of the NCT are greatly increased. In the NCT, the only necessary pilots to transmit are the DMRS (DeModulation Reference Signal) and the CSI-RS (Channel State Information-Reference Signal), and the PSS transmitted in the middle 6 RBs. /SSS and other signals.

In the LTE communication, when the base station transmits data to the UE (User Equipment, User Equipment) through the PDSCH (Physical Downlink Shared Channel), the base station notifies the UE of the number of resources used in the transmission (the number of RBs). , and a transmission employed in the modulation and coding scheme index IMCS (MCS (modulation and Code scheme ) index) 0 UE may 7.1.7.1-1 (modulation and TBS index table) according to the table to check the available transport block size TS36.213 Index I _TBS (Transport Block Size index), according to the number of I _TBS and RB according to Table 7.1.7.2-1, Table 7.1.7.2.2-1, Table 7丄7.2.4-1, Table 7.1.7.2.5-1 (TBS table) The number of information bits in the base station's transmission is checked and correctly decoded according to the standard convention. On the other hand, if the base station schedules the UE to perform uplink data transmission in a certain subframe through the PUSCH (Physical Uplink Shared Channel), the base station notifies the UE of the number of resources used in the scheduling (the number of RBs) and the scheduled uplink transmission. I _{MCS used} . The UE may find the I _TBS (modulation and TBS index relation table) from Table 8.6.1-1 according to I _MCS , and according to the number of I _TBS and RB according to Table 7.1.7.2-1, Table 7.1.7.2.2-1 Table 7.1.7.2.4-1 and Table 7.1.7.2.5-1 find the number of information bits of this transmission, and thus correctly encode according to the standard convention to complete the uplink transmission.

 However, in this NCT, since the legacy PDCCH is no longer transmitted, the transmission frequency of the CRS pilot is also transmitted once every 1 ms, and is changed every 5 ms, and the resources available for transmitting user data in each RB resource are greatly Increased, so the traditional Transport Block Size (TBS) form is no longer applicable.

 It should be noted that the above description of the technical background is only for the purpose of facilitating the clear and complete description of the technical solutions of the present invention, and is convenient for understanding by those skilled in the art. The above technical solutions are not considered to be well known to those skilled in the art simply because these solutions are set forth in the background section of the present invention.

 The foregoing and other features of the embodiments of the invention will be apparent from the These embodiments are merely exemplary and are not limiting of the invention. In order to enable the person skilled in the art to easily understand the principles and embodiments of the present invention, the embodiment of the present invention uses the base station to transmit downlink data to the UE or the base station to schedule the UE to perform uplink data transmission, and the UE determines the data for use by looking up the table. The data transmission control method of the embodiment of the present invention is described as an example. However, it can be understood that the embodiment of the present invention is not limited to the foregoing data transmission process, and is applicable to a data transmission process involving a table lookup.

 Example 1

 Embodiments of the present invention provide a data transmission control method. Figure 1 is a flow chart of the method. Referring to Figure 1, the method includes:

 Step 101: A user equipment (UE) receives a resource block (RB) number and a modulation and coding scheme (MCS) index sent by a base station for data transmission;

 When the base station sends the downlink data to the UE, the number of RBs used for data transmission and the MCS index refer to the number of RBs used in the transmission and the MCS index; when the base station schedules the UE for uplink data transmission The number of RBs used for data transmission and the MCS index refer to the number of RBs used by the UE to transmit data and the MCS cable.

 Step 102: The UE determines, by using the MCS index, a transport block size (TBS) index by querying a modulation and TBS index relationship table.

 The TBS index can be determined by querying the modulation and TBS index relationship table.

Step 103: The UE determines the number of information bits of the data transmission by querying the predetermined TBS table by using the RB number and the TBS index, and then correctly encoding or decoding the data. When the base station sends the downlink data to the UE, the UE can determine the number of information bits used by the base station in the data transmission by querying the TBS table (referred to as a predetermined TBS table) in the embodiment of the present invention. Decoding; when the base station schedules the UE to perform uplink data transmission, the UE can determine the number of information bits used by the uplink data transmission by querying the TBS table (referred to as a predetermined TBS table) of the embodiment of the present invention, thereby Correctly coded to complete the upstream transmission.

 In this embodiment, the predetermined TBS table includes a layer one table, a layer two table, a layer three table, and a layer four table, wherein the layer one table includes the number of information bits of each available RB number corresponding to each TBS index. . The behavior TBS index of the predetermined TBS table, the embodiment of the present invention follows the 0~26 modulation and coding scheme level in the standard TBS table, and has 27 levels. For example, the first row of the TBS table indicates that each TBS index is 0. An element corresponding to the number of available RBs, and the 27th line indicates an element corresponding to the number of available RBs having a TBS index of 26. The column of the predetermined TBS table is an available resource block (the number of RBs), and the number of available RBs is from 1 RB to 110 RB. For example, the first column of the TBS table indicates that the number of available resource blocks is 1 RB, and the 110th column Indicates that the number of available resource blocks is 110 RBs.

 In this embodiment, assuming DMRS (layers 4-8, layer concept see TS36.213, section 6.3) transmission, the number of available REs per RB is 12*14-12*2 = 144; assuming DMRS (4) Layer -8) When transmitting B CSI S (8 antenna ports), the number of available REs per RB is 12*14-12*2-8 = 136. Among them, the signal such as PSS/SSS and the extended CP (Cyclic Prefix) are not considered. In actual applications, when the above signal appears, the code is matched by the rate matching method stipulated in the standard TS36.212.

 In this embodiment, each element in the layer-by-table in the predetermined TBS table is determined by the method shown in FIG. 2. Referring to FIG. 2, the method includes:

 Step 201: Extract all TBS elements in the standard TBS table to generate a TBS element candidate sequence;

 In order to reduce the inconvenience of the upper layer in configuring the information, the embodiment of the present invention reuses the TBS element in the existing table as much as possible. The existing form, which is the TBS form used by the standard, is referred to as the standard TBS form in this embodiment, including Table 7.1.7.2-1-1 (Layer 1 form), Table 7.1.7.2.2-1 (Layer 2 form) ), Table 7.1.7.2.4-1 (Layer 3 table), Table 7.1.7.2.5-1 (Layer 4 table).

 The candidate sequence of the TBS element may be sequentially arranged, for example, by two columns, wherein the first column is an element number (index), and the second column is an element value.

Step 202: Calculate according to the code rate and modulation mode of the standard TBS table and the number of available REs per RB. Generating a first layer of a table draft corresponding to each TBS index and the number of information bits containing CRC bits for each available RB number;

 Among them, the number of RBs (1~110) and the number of available REs per RB (144 or 136), modulation mode (2 (QPSK) or 4 (16QAM) or 6 (64QAM)) and the current modulation coding scheme level (0~) 26) The code rate is multiplied and rounded up to determine the number of information bits containing the CRC bits, generating a

The 27*110 form is called the first level and a draft form.

 Among them, the behavior of the table TBS index, listed as the number of available resource blocks (RBs).

 Step 203: Remove the CRC bits in the information bits in the draft of the first layer, and generate a second layer of a draft;

 Wherein, since the elements contained in the standard TBS table do not contain CRC bits, in order to reuse the elements in the standard TBS table as much as possible, this embodiment also removes the CRC bits in the information bits of each element in the table.

 Wherein, the CRC bit in the information bits in the draft of the first layer can be reversely removed according to the method of adding the CRC bit in TS 36.212, thereby obtaining another table of 27*110, which is called the second layer and a draft of the table. .

 Among them, the behavior of the table TBS index, listed as the number of available resource blocks (RBs).

 Step 204: traverse each element in the second layer of a draft of a table, select an element having the smallest absolute value of the difference from the each element from the TBS element candidate sequence, and fill the selected element into the The position of each element is generated in a table of layers.

 For example, taking the target element A in the draft of the second layer and the table as an example, the element having the smallest absolute value of the difference from the element A is selected from the candidate sequence of the TBS element extracted in step 201, and is filled in as the corresponding element of the element A. The location of A. By performing this processing on each element in the second layer of a draft, a layer-by-table is obtained.

 Similarly, the behavior of this layer-table is TBS index, and the column of this layer is listed as the number of available resource blocks (RBs). In an embodiment, if the absolute value of the difference between the two elements in the TBS element candidate sequence and the one element in the second layer of the table draft is the smallest, according to the code rate corresponding to the two elements, An element having a smaller absolute value of the difference from the target bit rate of the row in which the one element is located is selected as the element at the position of the one element in the layer-one table.

For example, in the TBS element candidate sequence, there are two elements having the smallest absolute value of the difference from the aforementioned element A, respectively B and C (that is, the absolute values of the differences between B and C and A, respectively, are the smallest and the same ), then this implementation For example, by calculating the code rates of the element B and the element C, the absolute values of the difference between the code rate corresponding to the element B and the element C and the target code rate of the line of the element A are compared, and the element having the smaller absolute value of the difference is selected. As the corresponding element of element A, fill in the position of element A.

 The method for calculating the code rate of each element is the same as the prior art. The CRC bits need to be calculated as information bits, and details are not described herein.

 In one embodiment, if an element having a code rate greater than a predetermined code rate threshold is in an element of the last row (27th line, that is, the TBS index is 26) of the layer-one table, the candidate from the TBS element An element in the sequence whose element number is one less than the element number of the element is taken as an element at the position.

In this embodiment, a code rate threshold may be preset, for example, 0.93. In order to avoid that the code rate of the element of the last row (I _TBS = 27) of the layer one table is greater than the code rate threshold, in this embodiment, after determining the elements of the layer one table by the foregoing method, the elements of the last row are also calculated. The code rate, if the code rate of an element is greater than the foregoing rate threshold, that is, 0.93, an element whose element number is one less than the element number of the element is selected from the TBS element candidate sequence as an element at the position.

 For example, by calculating the code rate of each element of the last row, it is found that the code rate corresponding to the element D is greater than 0.93, and the sequence number of the element D in the TBS element candidate sequence is d, then the sequence number of the TBS element candidate sequence is selected as d-1. The element acts as an element at the corresponding position of element D.

 The method for calculating the code rate of each element is the same as the prior art. The CRC bits need to be calculated as information bits, and details are not described herein.

In one embodiment, in order to be consistent with the original table, that is, the seventh element of the first column (the element with the I _TBS number of 6) is 328, the elements of the layer one table are also adjusted. Wherein, if the number of available resources of each resource block (RB) is 144 resource particles (RE), the seventh element of the first column (the number of available RBs is 1) of the layer one table is changed to 328; If the number of available resources per resource block (RB) is 136 resource particles (RE), then the 3-7th element of the first column (the number of available RBs is 1) of the layer one table is substituted for the column in order. The 2-6th element, and the 7th element of the column is changed to 328.

In one embodiment, the generated table may be in the same situation, that is, in the same column of the layer one table, different TBS indexes (I _TBS ) correspond to the same element, in order to increase the flexibility of scheduling, to avoid this situation, Also adjust the elements of the layer one table. Wherein, except for the element with the value 328 in the first column, for each column of the layer-one table, traversing each element in the same column, if there are two elements with different TBS indexes but the same value, the TBS index is smaller. The element uses an element of the candidate sequence that is one less than the element number Instead. Then check whether there are two elements in the column with different TBS indexes but the same value. Repeat the above steps until each TBS index in the column corresponds to a different element.

 By the method of this embodiment, a layer-one table of the TBS table applicable to the new carrier type can be determined. The following table is a new TBS table produced by the embodiment of the present invention when the number of available resources per RB is 144 RE.

 In one embodiment, to support the transmission of MAC signaling and VoIP traffic, the following TBS elements are included in the TBS table of the present embodiment, and the following TBS elements are kept as close as possible to the frequencies appearing in the new and old tables. These elements include: 16, 24, 40, 56, 72, 104, 120, 144, 152, 176, 208, 224, 256, 296, 328, 344, 392, 440, 488, 504, 536, 568. This embodiment adjusts the above elements such that the frequency of occurrence of these elements in the layer-one table is close to the standard TBS table.

 The following table is a comparison table of the number of occurrences of the above elements in the standard TBS table and the number of occurrences in the TBS table of the embodiment of the present invention when the number of available resources per RB is 144 RE:

在本实施例中，该所述预定的 TBS表中的层二表格中的各元素可以通过图 3所示 的方式确定， 请参照图 3， 包括：

In this embodiment, each element in the layer two table in the predetermined TBS table may pass through FIG. 3 The way to determine, please refer to Figure 3, including:

 Step 301: Extract elements of columns 56-110 in the layer one table;

 Step 302: Select, from the candidate sequences, an element having the smallest absolute value of the difference between the extracted elements and the element value of each element to generate a layer two table.

 Among them, based on the previously determined layer-one table, the method of using the layer two table is consistent with the existing standards. That is, when the transmission layer is Layer 2, it is assumed that the number of available RBs is N. If N is less than or equal to 55, the elements corresponding to the corresponding TBS index in the 2Nth column of the lookup layer table are directly used as the result of the lookup table. If N is greater than or equal to 56, the element X corresponding to the corresponding TBS index of the Nth column of the table is searched, and then X is found in the first column of the second table, and the element of the second column of the X row is read as the The results of the second lookup table.

 Wherein, based on the size of the extracted element sequence, the candidate sequence having the smallest absolute value is found as the layer two table in the candidate sequence.

 The following table shows the layer two table generated according to the above layer one table when the number of available resources per RB is 144 RE. The elements in the first column correspond to the elements in the layer one table, and the elements in the second column are the elements corresponding to the elements in the first column.

 In this embodiment, each element in the layer three table in the predetermined TBS table can be determined by the method shown in FIG. 4. Referring to FIG. 4, the method includes:

 Step 401: Extract elements of columns 37-110 in the layer one table;

 Step 402: Select, from the candidate sequences, an element having the smallest absolute value of the difference of three times the extracted elements as an element value of each element, to generate a layer three table.

 Among them, based on the previously determined layer-one table, the method of using the layer three table is consistent with the existing standards. That is, when the transmission layer is three layers, it is assumed that the number of available RBs is N. If N is less than or equal to 36, the element corresponding to the corresponding TBS index of the 3N column of the search layer 1 is directly used as the result of the lookup table. If N is greater than or equal to 37, the element X corresponding to the corresponding TBS index of the Nth column of the table is searched, and then X is found in the first column of the third table, and the element of the second column of the X row is read as the current time. Check the results of the table.

 Wherein, the candidate sequence with the smallest absolute value difference is found in the candidate sequence as the layer three table based on the three times the size of the extracted element sequence.

 In this embodiment, each element in the layer four table in the predetermined TBS table can be determined by the method shown in FIG. 5. Referring to FIG. 5, the method includes:

 Step 501: Extract elements of columns 28-110 in the layer one table;

 Step 502: Select, from the candidate sequences, an element having the smallest absolute value of the difference of 4 times of each extracted element as an element value of each element, and generate a layer four table.

 Among them, based on the previously determined layer-one table, the method of using the layer four table is consistent with the existing standards. That is, when the transmission layer is four layers, it is assumed that the number of available RBs is N. If N is less than or equal to 27, the element corresponding to the corresponding TBS index of the 4Nth column of the search layer 1 is directly used as the result of the lookup table. If N is greater than or equal to 28, the element X corresponding to the corresponding TBS index of the Nth column of the table is searched, and then X is searched for in the first column of the fourth table, and the element of the second column of the X row is read as the current time. Check the results of the table.

 Wherein, based on the 4 times the size of the extracted element sequence, the candidate sequence with the smallest absolute value difference is found in the candidate sequence as the layer four table.

 In one embodiment, since the number of REs available for transmitting data per RB of the NCT is increased compared to the conventional carrier, there are several relatively large elements for the table of layer four (extracted in step 501). A suitable candidate cannot be found, and the embodiment of the present invention selects a new element for these elements by the method shown in FIG. 6 for this case. It is assumed that for the same TB (Transport Block), all CBs (Code Blocks) have the same size, that is, the information bits of each CB are the same. Referring to FIG. 6, the method includes: Step 601: determining an initial value of a new element according to an element S that does not find a suitable candidate;

 Among them, the element S which does not find a suitable candidate S means that, from the 28th to the 110th columns of the layer one table, no suitable candidate element is found. The initial value of this new element is 4 times S, which is 4S.

Step 602: Calculate two block numbers BLId and BLK ₂ of the initial value of the new element by using the upper rounding and the bottom rounding method respectively according to the following formula _:

 = [(54 + 24)/ 6120]; J^ = LCS4 + 24) /6120".

 Where S is the aforementioned element that does not find a suitable candidate, and the method shown in Figure 6 is to find candidate elements for these elements.

Among them, based on the factor 4 (S4) of the element, under the condition that the coding block (CB) is equal, the two block numbers 81^ and BLK ₂ are calculated by the upper rounding and the lower rounding respectively. Step 603: Find the size of the coding block corresponding to BLK ₂ , that is, find and +24

BLK _X

And (S4 + 24) + ₂₄ closest interleaver L and _l2;

BLK ₂

Step 604: Calculate two candidate values of the new element according to the interleaver according to the following formula;

= (/ ₂ - 24) H ₂ _24.

 Wherein, by removing the CRC bits in the coding block, two candidate values for obtaining the new element can be calculated by using the above formula.

 Step 605: Select a larger value in S1 and S2 that satisfies the preset target padding rate as a new element.

Wherein, the target fill rate can be 4%, that is, if ίΗ^1⁄2 ^ ≤ 4%, then max^^A) is used as max(5' ₁ , ₁ S' ₂ )

Is a new element of the element; otherwise ηώι(3⁄4 ₂ ) is used as the new element of the element.

 Where ΤΒ is the value of the element that is one less than the sequence number of the above new element. 4% is the target padding rate set in this embodiment, but this embodiment is not limited thereto.

 The following table shows the four-layer four-layer table generated from the above-mentioned layer-one table when the number of available resources per RB is 144 RE. The elements in the first column correspond to the elements in the layer one table, and the elements in the second column are the elements corresponding to the elements in the first column.

 Step 901: The number of information bits to be downlinked to the UE by the base station, the number of information bits to be uploaded on the UE side, the current resource allocation, the channel link quality between the UE and the base station, the modulation and TBS index relationship table, and the TBS table. Selecting, for the UE, a number of RBs for performing data transmission and an MCS index;

 For the scenario in which the base station sends downlink data to the UE, the number of information bits of the downlink data to be downlinked to the UE, the current resource allocation, the channel link quality between the UE and the base station, and the modulation and TBS index relationship table. And the TBS table selects the number of RBs for the downlink data transmission and the MCS cable for the UE.

 The scenario in which the base station schedules the UE to send uplink data, the base station according to the number of information bits of the uplink data to be uploaded by the UE side, the current resource allocation, the channel link quality between the UE and the base station, the modulation and TBS index relationship table, and The TBS table selects the number of RBs for the uplink data transmission and the MCS cable for the UE.

Step 902: The base station sends the number of RBs and the MCS index to the UE, so that the UE is configured according to the UE. Determining, by the MCS index, the TBS index by combining the modulation and TBS index relationship table, and determining the number of information bits of the current uplink transmission or the downlink transmission according to the RB number and the TBS index according to the predetermined TBS table, and then correctly encoding or decoding. The data.

 In a scenario where the base station sends the downlink data to the UE, the method further includes:

 Step 903: After receiving the uplink data sent by the UE, the base station searches the modulation and TBS index relationship table according to the MCS index, and determines a TBS index.

 Step 905: The base station demodulates and decodes the received uplink data according to the information bit number.

 After the base station learns that the UE has uplink data to be transmitted, the base station refers to the number of information bits to be transmitted, the current resource allocation, and the channel link quality between the current UE and the base station, and refers to the relationship between modulation and TBS index. The table and TBS table select the size (RB number) of the transmission resource block and the MCS index for the UE, and notify the UE of relevant information (such as resource block size and location and MCS index used in transmission) before actually performing line data transmission. The UE determines the TBS index by checking the modulation and TBS index relationship table according to the MCS index indicated by the base station, and determines the information bit size of the transmission by checking the TBS table according to the RB number and the TBS index (wherein, the information bits in the cache of the UE) The UE does not necessarily read the corresponding number of information bits, and then the UE reads the corresponding number of information bits from the buffer, and then encodes and modulates the information bits to be transmitted according to the corresponding MCS index, and performs uplink transmission on the time and frequency resources specified by the base station. . After receiving the uplink data sent by the UE, the base station checks the size of the information bits transmitted from the TBS table according to the agreed TBS index, and demodulates and decodes the received data accordingly.

 When the base station sends the downlink data to the UE, the base station firstly determines, according to the number of information bits of the downlink data, the current resource allocation, the channel link quality between the UE and the base station, the modulation and TBS index relationship table, and the TBS table. The UE selects the number of RBs for performing the foregoing downlink data transmission and the MCS index, and then the base station sends the RB number and the MCS index to the UE, so that the UE combines the modulation and the TBS index according to the MCS index. The relationship table determines the TBS index, and determines the number of information bits of the downlink data according to the RB number and the TBS index in combination with the predetermined TBS table, thereby correctly decoding the data.

In this embodiment, the TBS table that the base station searches for is the same as the TBS that the UE searches for. The specific content of the TBS table has been described in detail in Embodiment 1, and the content thereof is incorporated herein, and details are not described herein again. Through the method of the embodiment, the base station uses a new TBS table in the data transmission process, and expands resources available for transmitting data in each resource block, thereby improving data transmission efficiency.
