Description

Process management and coding method and device in multi-carrier time division duplex system

The present invention provides a HARQ process management method and apparatus suitable for uplink multi-carrier time division duplex (TDD) system, and improves the efficiency and flexibility of data transmission by independently managing HARQ processes of each carrier. . The present invention also provides a coding method, coding and/or decoding apparatus for a High Speed Uplink Packet Access (HSUPA) service transmission channel in a multi-carrier TDD system. Background technique

The 3rd Generation Partnership Project ("3 GPP"), as an important organization in the field of mobile communications, promoted the standardization of the third generation of mobile communication (The Third Generation, referred to as "3G") technology. The bearer of the uplink and downlink services in the protocol version is based on the dedicated channel. Among them, the 99 version (Release 99, referred to as "R99") can achieve the data transmission rate of 384 kilobits per second (Kbps).

In the existing 3GPP technical standards, regardless of FDD (Frequency Division Multiplexing) or TDD (Time Division Multiplexing), the uplink terminal supports only one carrier, FDD can provide an uplink peak rate of 5.7 Mbps, and the uplink of LCR TDD can only Provides a peak rate of 2.2Mbps.

With the development of mobile communication technology, 3G technology is also evolving. Many data services that require high traffic and latency, such as video, streaming, and download, require higher transmission rates and shorter latency. High Speed Uplink Packet Access (HSUPA) is an important evolution of 3G technology. Different from the scheduling and retransmission of data packets in the R99 version, it is controlled by the Radio Network Controller (RNC). The scheduling and retransmission of data packets in HSUPA are performed by Node B (NodeB, also called base station). Control, this control is faster, can better adapt to channel changes, reduce transmission delay and increase data throughput. In HSUPA, a technique of introducing multiple uplink carriers in parallel transmission may be considered. For example, when three uplink carriers are used for parallel transmission, a peak rate of 6.6 Mbps can be obtained, and spectrum utilization is also greatly improved. High.

As a high-speed uplink packet access technology, HSUPA was introduced in the version of 3GPP Release 6 ("R6") in 2004. HSUPA uses a shorter Transmission Timing Interval (" ΤΤΓ") and a frame length (2ms or 10ms) for fast adaptive control, using Hybrid Automatic Repeat Request ('HARQ"). ) and fast uplink scheduling technology based on Node B; improve the data transmission rate in the uplink direction.

The HARQ technology combines forward error correction code and retransmission for fast retransmission of the physical layer of the Enhanced Dedicated Channel (E-DCH), and through soft combining between initial transmission and retransmission. To improve the decoding performance of the physical layer.

Since the existing standards are designed for single-carrier technology, some processes and structures are not applicable to multi-carrier systems, and the HARQ process is the most affected. The following describes the HARQ principle and process in the existing HSUPA technology.

In order to perform fast feedback retransmission of data blocks with incorrect transmission and to make full use of the information carried by the erroneous data through data block merging, HARQ technology has been adopted as a better solution by multiple systems. HSDPA (High Speed Downlink Packet Access), HSUPA, and future LTE all use HARQ protocol such as multi-way parallel stop to support continuous scheduling and transmission of data. The so-called stop, etc., means that after using a HARQ process to transmit a data packet, it cannot continue to use the process to transmit any other data before receiving the feedback information. The advantage of the stop protocol is that it is relatively simple, but the transmission efficiency is relatively low. The use of multiple parallel stop protocols and simultaneous initiation of multiple HARQ processes can make up for the shortcomings of low transmission efficiency. The basic idea is to configure multiple HARQ processes at the same time. In the process of waiting for feedback information of a HARQ process, other idle processes can continue to transmit data packets. In order to distinguish different HARQ processes, a HARQ process identifier needs to be introduced, and the HARQ process identifier is usually carried by the data transmitting end through the control channel.

Two transmission modes are defined in HSUPA: scheduled transmission and unscheduled transmission. For some services that are insensitive to delay and service rate, such as WWW, FTP, etc., the system usually adopts a unified scheduling method, so-called scheduling transmission, to improve system throughput by reasonably allocating resources among multiple service flows. For the purpose of throughput, one disadvantage of unified scheduling is that multiple control channels need to be configured. For some services that have certain requirements on the service rate and the data arrives regularly, such as video streams, the method can be used to periodically allocate resources. This allocation method can pass the high-level letter when establishing the service connection. It is implemented without additional scheduling channel support, so it is called unscheduled transmission.

In order to perform fast feedback and retransmission of erroneous data blocks, both the scheduled transmission and the non-scheduled transmission adopt the HARQ process protocol such as multiple parallel stop. In the existing single-carrier HSUPA technology of TDD, any one of the TTIs can perform scheduled transmission or non-scheduled transmission. Both the scheduled transmission and the non-scheduled transmission can use four HARQ processes, and both of them use two bits to represent the HARQ process identifier. The terminal first determines what nature of the transmission is, and then submits it to the corresponding process for processing.

After the introduction of the multi-carrier technology, the uplink allows multiple data blocks to be transmitted in parallel on multiple carriers. Each data block needs to be processed by one HARQ process. The number of processes defined by the existing single-carrier system and the process management method cannot be directly applied. For multi-carrier systems.

In addition, the high-speed uplink packet access service transmission channel in the HSUPA is an E-DCH. As shown in FIG. 1 , the coding method of the service transmission channel using the single-carrier HSUPA technology in the prior art includes the following steps: Step 101: The sender device is The data block to be sent adds a CRC check bit, through which the receiving device can check whether there is an error in the received data; this step is to implement CRC addition.

Step 102: The sending end device performs segmentation according to the length of the sent data block, and performs preprocessing for subsequent channel coding. This step is to implement code block segmentation.

Step 103: The transmitting device performs channel coding on the segmented data block, so that the receiving device can correct most errors in the transmission according to the channel coding; the step is to implement channel coding.

Step 104: The source device performs rate matching processing on the encoded data, generates different data bit patterns through rate matching puncturing or repeated operations, and implements HARQ function through HARQ retransmission and merging. This step is to implement physical layer HARQ. Features.

Step 105: The sending end device scrambles the matched processing data, so that the sent data is further randomized, improving the performance of the transmission, and reducing mutual interference; the step is to implement data scrambling.

Step 106: The sending end device performs interleaving processing on the scrambled data, and the interleaved data is performed. Sending in different time slots, acquiring time diversity gain, improving the ability to resist burst errors; this step is to achieve data interleaving.

Step 107: When the modulation mode of the data transmission adopts the 16QAM mode, if a retransmission occurs, the transmitting device needs to swap or/and invert the preceding and succeeding bits of the constellation point of the retransmitted data, so as to balance the high bits in the constellation point. The performance of bit and low bit data; this step is to achieve 16QAM constellation rearrangement.

Step 108: The sending end device adapts the sending data to different physical channels for data transmission; the step is to implement physical channel mapping.

In the prior art, the decoding of the E-DCH at the receiving end device needs to enhance the cooperation of the uplink control channel (E-UCCH), and the information necessary for the E-DCH decoding on the E-UCCH, including the data block size information (E) -TFCI), retransmission sequence number information (RSN) and HARQ process identification information (PID).

And, the transmitting device multiplexes the E-UCCH and the E-DCH and then multiplexes it onto the uplink enhanced physical channel (E-PUCH) for transmission. An E-PUCH transmission may carry data of multiple E-UCCHs at the same time, and data carried on multiple E-UCCHs is completely consistent, and the purpose is to combine data of multiple E-UCCHs at the receiving end device to improve decoding. performance.

The prior art adopts single-carrier HSUPA technology, and the methods for multiplexing E-UCCH and E-DCH data are as follows:

Let E-DCH transmission occupy the number of slots, and the number of E-UCCHs transmitted at the same time is: M = floor{ENIIT) . N = ENI%T ; where ⁰⁰ (') indicates rounding down; The number of E-UCCHs carried in each time slot is:

The number of E-UCCHs carried in the first W time slots in the T time slots = M +1;

The number of E-UCCHs carried by the following ^T _ ^N "> slots in ^T time slots = M;

In the prior art, for single-carrier HSUPA technology, multiple E-UCCHs of the same user can only be transmitted on a single carrier, and the effect of frequency diversity in multi-carrier transmission cannot be obtained, resulting in a low uplink data rate of the TDD system.

Similarly, the prior art is directed to single carrier HSUPA technology, for each transmission of the same terminal Inter-interval (ΤΉ) can only have one E-DCH type coded combined channel. Considering the different characteristics of unscheduled transmission and scheduled transmission, the same terminal cannot simultaneously perform scheduled transmission and non-scheduled in the same TTI on a single carrier. Transmission causes the uplink data rate of the TDD system to be low.

In summary, the disadvantages of the prior art are: for multi-carrier HSUPA, the UE may transmit multiple data packets in a certain TTI, so that multiple HARQ processes need to be started, how to use and manage these HARQ processes, the existing protocol There is a lack of necessary description. Moreover, the prior art high speed packet service transmission channel coding procedure is mainly directed to a single carrier TDD system and cannot meet the needs of a multi-carrier TDD system. In addition, based on the current 3GPP protocol, for a single carrier HSUPA, multiple E-UCCHs of the same user can only be transmitted on a single carrier, and the effect of frequency diversity in multi-carrier transmission cannot be obtained; likewise, a terminal with single carrier capability Scheduling and non-scheduled transmissions cannot be performed simultaneously in the same frame. The above disadvantages result in the TDD system not being able to obtain a higher peak rate of uplink data and the concurrency of scheduling transmission traffic and non-scheduled transmission traffic. Summary of the invention

Combining the characteristics of the multi-carrier TDD system, the present invention proposes three implementation schemes of the coding method of the HSUPA traffic transmission channel in the multi-carrier TDD system, and simultaneously proposes three implementations of the coding apparatus of the present invention corresponding to the three implementation schemes. The solution, the three implementations of the decoding device of the present invention, and the three implementations of the codec device of the present invention.

The first implementation manner of the coding method provided by the present invention is as follows: First, the high-speed packet data to be transmitted is divided into N groups, and each group of data is separately subjected to CRC addition, code block segmentation, channel coding, and physical layer HARQ function module. The processing of the N sets of the matched processed data is uniformly scrambled and interleaved, and then divided into N groups of M-QAM constellations rearranged and mapped to the physical signals of the corresponding carriers. Road transmission. Furthermore, when a terminal having multi-carrier transmission capability transmits data using multiple carriers, the same

In the TTI, data carrying different transmission modes is allowed on different carriers, that is, the multi-carrier terminal is allowed to perform scheduled transmission and non-scheduled transmission on different carriers in the same TTI. With this implementation, the interleaving gain between the time interleaving gain and the frequency can be brought about, and the burst error in the user data transmission is changed to a random error to improve the decoding performance.

The second implementation of the coding method provided by the present invention is: after the high-speed packet data to be transmitted is divided into several groups, each channel of data can be encoded according to the coding mode of the single-carrier high-speed packet service transmission channel. The transmission is performed through the physical channel of the corresponding carrier. Further, when a terminal having a multi-carrier transmission capability uses multiple carriers to transmit data, data of different transmission modes is allowed to be carried on different carriers in the same TTI, that is, the multi-carrier terminal is allowed to perform scheduled transmission on different carriers in the same TTI. And unscheduled transfers. Because of this implementation scheme, each channel of data can be processed separately on each carrier, and no combination is performed, that is, data of each carrier is transmitted as independent data, and each channel of the data can be regarded as mutual Not relevant, therefore, using this implementation is both simple and practical.

The third implementation manner of the coding method provided by the present invention is: sending N carrier channels as a whole to the physical layer processing, and no longer blocking the high-speed packet data that needs to be sent, from CRC addition to processing. After the interference, the data is interleaved, and then the M-ary QAM constellation rearrangement is performed, and finally, the corresponding carrier channel is mapped for transmission. For the transmitting device, the implementation of the channel is regarded as a whole processing by using the implementation scheme, and the process of the channel coding process is simple and easy to implement, and a certain interleaving gain can be brought according to different data interleaving methods.

Moreover, the three implementations of the encoding method provided by the present invention enable multiple E-UCCHs of the same user to be transmitted on multiple carriers, and the effect of frequency diversity in multi-carrier transmission can be obtained; and the present invention provides The first two implementations of the coding method allow a terminal with multi-carrier transmission capability to transmit data in different transmission modes on different carriers in the same TTI when multi-carrier transmission capability is used; that is, multi-carrier terminals are allowed to be in different carriers in the same frame.

In order to make the objects and technical solutions of the present invention more comprehensible, the present invention will be further described in detail below with reference to the accompanying drawings.

The implementation process of the hybrid automatic retransmission method in the multi-carrier high-speed uplink packet access of the present invention is given by taking the HSUPA technology of the LCRTDD as an example. FIG. 2 is a flowchart of an implementation process of a hybrid automatic retransmission method in multi-carrier high-speed uplink packet access according to an embodiment of the present invention, and each step is as follows:

Step A: The base station and the terminal respectively establish a hybrid automatic repeat request HARQ entity for each available carrier of the terminal, and the HARQ entity is responsible for managing the HARQ process corresponding to the carrier.

The multi-carrier TDD uplink HARQ process management method provided by the embodiment of the present invention allocates a corresponding HARQ process for each carrier that can be used by the UE, and the HARQ processes of different carriers are independent of each other, and the carrier used by the traffic channel corresponds to the TTI bearer. The service type and the process identification ID carried on the corresponding control channel jointly identify the process, and complete the subsequent data processing. The above control channel may be an E-UCCH (Enhanced Uplink Control Channel).

The base station maintains a HARQ process mapping table for each terminal communicating with the base station, where the HARQ process mapping table records the identity of each HARQ process, the transmission mode (scheduled transmission mode or non-scheduled transmission mode) to which the HARQ process belongs, and the HARQ. The carrier to which the process belongs. The HARQ process mapping table can be recorded while the HARQ process is being allocated.

As shown in FIG. 3, the HARQ process mapping table in the embodiment of the present invention represents the correspondence between the carrier identifier and the HARQ process identifier allocated by the network side for the terminal. Wherein, in each carrier that can be used by the multi-carrier terminal, the HARQ processes allocated on each carrier are grouped according to the transmission mode (scheduled transmission and non-scheduled transmission) used by the service, and each HARQ process belongs to and belongs to only one In the HARQ process group, each HARQ process group on each carrier corresponds to a certain transmission mode, and the HARQ process in each HARQ process group has a unique identifier. In this way, if the terminal identifier is known, the base station can find the HARQ process mapping table maintained for the terminal; and after finding the HARQ process mapping table, if the carrier identifier, the transmission mode used by the service corresponding to the TTI, and the HARQ process identifier are known, The only one is to determine a HARQ process.

The terminal maintains a HARQ process mapping table identical to the HARQ process mapping table maintained by the base station for the terminal. The method of determining a HARQ process on the terminal side is the same as that on the base station side.

Step B: The network side allocates uplink resources to the terminal.

When the network side allocates resources to the terminal, it usually takes into account the user's traffic, service priority, and information. According to factors such as channel conditions, the allocated resources include carrier resources, time slot resources, power resources, and code channel resources. The number of carriers allocated by the network side for the terminal shall not exceed the maximum number of carriers supported by the terminal.

R C and NodeB are included in the existing network side architecture. When the uplink resource is allocated to the terminal, the uplink resource of the unscheduled transmission is pre-allocated by the radio network controller on the network side, and the resources scheduled for transmission are dynamically allocated by the base station. In the subsequent technology evolution, the network side may have no RNC, but replace the existing RNC and NodeB with an enhanced NodeB. In this case, the resources of the unscheduled transmission are pre-allocated by the enhanced NodeB, and the transmitted resources are scheduled. Dynamically allocated by the enhanced base station.

In addition, if a resource of a non-scheduled transmission mode has been allocated to the terminal within a certain transmission time interval TTI of a certain carrier, the terminal is no longer allocated a scheduling transmission mode for the terminal in the TTI of the carrier. resource of.

Step C: The terminal assembles the data packet according to the uplink resource allocated by the network side, determines the used carrier for each of the data packets, and selects the HARQ process by the HARQ entity corresponding to the carrier.

There are several principles to follow when assembling a package:

1) assembling a data packet for each available carrier that is currently allocated at the terminal;

2) If the network side allocates resources for a service using the scheduled transmission mode in a certain carrier, the service flow from the use of the scheduled transmission mode and the service flow that allows the scheduling transmission mode are multiplexed in the carrier. Select data in the service flow to assemble the data packet;

3) If the network side allocates resources for a service using a non-scheduled transmission mode in a certain carrier, the service flow from the non-scheduled transmission mode and the service flow in the non-scheduled transmission mode are used in the carrier. Selecting data from the multiplexed service stream to assemble the data packet;

4) If the terminal has a data packet waiting for retransmission and the uplink resource allocated for the terminal allows it to complete the retransmission, the new data packet is no longer assembled.

The terminal side selects a carrier and a HARQ process in the carrier for each data packet according to the HARQ process mapping table recorded and maintained. The HARQ entity on the terminal side needs to follow the following principles when selecting a carrier and a HARQ process in the carrier for the data packet:

1) if the network side allocates resources of a certain carrier to the terminal, the HARQ process corresponding to the carrier is selected; 2) if the network side allocates multiple carriers for the terminal, the HARQ process corresponding to the carrier is independently selected in each of the allocated carriers;

3) if the network side allocates resources for the service using the scheduled transmission mode on the terminal, and selects from the HARQ process whose transmission mode is the scheduled transmission mode;

4) if the network side allocates resources for the service using the non-scheduled transmission mode on the terminal, and selects from the HARQ process whose associated transmission mode is the non-scheduled transmission mode;

5) If there is a newly assembled data packet, select an idle HARQ process in the HARQ process corresponding to each carrier that the terminal can use;

6) If there is a data packet waiting for retransmission, select the same HARQ process as the initial transmission of the data packet.

Before the step A, the network side determines, according to the request information of the terminal, the uplink carrier set that the terminal can use, and notifies the terminal of the available uplink carrier set.

Step C further includes the following steps: The process sends the data packet, and notifies the base station of the HARQ process identifier used by the data packet.

The HARQ process identifier used by the data packet by the base station may be notified by the control channel, for example, according to the HARQ process identifier carried on the control channel, and submitted to the corresponding HARQ process. The above control channel may be an E-UCCH (Enhanced Uplink Control Channel).

E. The base station receives the data packet sent by the terminal on the allocated carrier, and submits the data packet to the corresponding HARQ process for processing.

Since the base station knows which carriers are allocated to the terminal, and which time slots and code channel resources are allocated to each carrier, the reception of the data packet can be smoothly completed. After receiving, you need to submit it to the corresponding process for processing. The method for determining the process is as follows:

El. The base station determines the terminal and the carrier to which the received data packet belongs, determines the uplink resource of the received data packet, and allocates the HARQ process identifier carried on the control channel.

E2. According to the HARQ process mapping table maintained by the base station for the terminal, follow step E1. The carrier to which the data packet belongs, the transmission mode, and the HARQ process identifier determine a unique HARQ process. That is to say, first, it is judged which terminal and which carrier the data packet received by the base station comes from. It has been explained in step A that the identifier of the terminal is found, the HARQ process mapping table can be found, then the carrier branch is judged, and then the current resource is scheduled or unscheduled, and the branch of the resource attribute is determined; and then according to the control channel The HARQ process identifier can uniquely identify a HARQ process and deliver the data packet to the HARQ process.

E3. The data packet is delivered to the HARQ process in step E2 for processing.

If the received data packet is a new data packet, the HARQ process directly performs decoding, and if the decoding is correct, the data packet is submitted to the higher layer processing and the acknowledgement message ACK is fed back to the terminal; otherwise, the data packet is stored in the soft buffer. And transmitting, by the base station side HARQ entity, a non-confirmation message NACK to the terminal; if the received data packet is a retransmission data packet, the HARQ process combines the data packet with the data packet in the soft buffer, and combines Decoding, if the decoding is correct, submit to the higher layer processing and feed back the acknowledgment message ACK to the terminal; otherwise, the data packet is stored in the soft buffer, and the non-confirmation message NACK is fed back to the terminal by the base station side HARQ entity.

The basic idea of the hybrid automatic retransmission method in the multi-carrier high-speed uplink packet access provided by the embodiment of the present invention is described above. In order to implement the present invention, it is also necessary to modify the MAC protocol structure of the base station and the terminal in the prior art. In the existing system, the MAC protocol structures of the base station and the terminal are as shown in Figs. 4 and 5, respectively. The base station establishes a HARQ entity for each terminal using HSUPA in itself.

After the present invention, the HARQ entity part in the base station and the terminal needs to be extended, and the same number of HARQ entities are established according to the number of carriers used in establishing the connection, and each HARQ entity is responsible for managing the HARQ process corresponding to one carrier, and the management method is in front. Already given. The MAC protocol structure of the base station and the terminal in the embodiment of the present invention are as shown in FIG. 6 and FIG. 7, respectively.

In addition, since the multi-carrier TDD system is characterized in that the multi-carrier TDD system allows the same user to simultaneously transmit or receive data using multiple carriers, the present invention combines the characteristics of the multi-carrier TDD system with multi-carrier HSUPA technology in multiple When the coding scheme of the carrier HSUPA traffic transmission channel is designed, one large data block may be transmitted on multiple carriers, or one independent data block may be transmitted on multiple carriers. The HSUPA service transport channel here includes the enhanced dedicated channel E-DCH in the HSUPA system, and can be extended to the transport channel carrying the HSUPA service in other multi-carrier TDD systems.

The encoding method of the HSUPA service transmission channel in the multi-carrier TDD system provided by the embodiment of the present invention is further described in detail below.

Embodiment 1:

In the first implementation scheme of the coding method of the HSUPA traffic transmission channel in the multi-carrier TDD system provided by the embodiment of the present invention, N represents the number of carriers used for high-speed packet data transmission of the user terminal; M in the M-element constellation rearrangement Includes 16 or 64. In this embodiment, the TDD system with the number of carriers is used as an example. The implementation in this embodiment includes the following steps: Step 201: The high-speed uplink data sending device located at the terminal side is to be configured. The transmission data is divided into three paths, and CRC addition, code block division, channel coding, and prior processing of the physical layer HARQ function module are performed separately.

Wherein, when the terminal-side transmitting device with multi-carrier transmitting capability uses multiple carriers to transmit data, the same carrier may perform scheduled transmission or non-scheduled transmission on different carriers, and may also carry data of different transmission modes, that is, the terminal The side sender devices can perform scheduled transmission and non-scheduled transmission on different carriers in the same TTI. For example, the terminal side transmitting end device may send unscheduled transmitted data on the carrier A, and transmit the scheduled transmission data on the carrier B and the carrier C, thereby transmitting the unscheduled transmission and the scheduled transmission simultaneously, and does not block each other. .

Step 202: Combine the three channels of data processed in the previous step 201 into one channel of data, and perform data scrambling processing uniformly. Step 203: Perform data interleaving processing on the data processed in step 202. The processing manner of the data interleaving in the step 203 in this embodiment may be the following three types, but is not limited to the three types.

The processing method of the first type of weaving is: dividing the data processed in step 202 into three paths, and the length of each data is the same as the length of the data after the step 201 is processed first; Each channel of data carries out data interleaving of single-channel data; then combines three channels of data in turn, and then performs overall interleaving; finally, it is divided into three channels of data in turn, and the length of each channel of data and the length of data before processing in step 201 the same.

Here, the data interleaving of the single channel data is a single channel interleaving, which means that each channel of data is separately input into the interleaving matrix for interleaving. The time diversity gain of the channel can be achieved by using one-way interleaving.

Combining the three channels of data in sequence means outputting the first channel data first, then sequentially outputting the second channel data, the third channel data, and merging the three channels of data.

The overall interleaving is distinguished from the single interleaving, and the three combined data sequentially input into the interleaving matrix are interleaved. The frequency interleaving gain of the channel can be obtained by using the overall interleaving.

The processing method of the second woven data interleaving is as follows: For the data processed in step 202, only the overall interleaving is performed, and then the data is divided into three channels, and the length of each data and the length of the data processed in step 201 are processed first. the same. '

The processing method of the third type of data interleaving is as follows: First, the data processed in step 202 is interleaved as a whole, and then divided into three pieces of data in turn, and the length of each line of data is the same as the length of the previously processed data in step 201. Then, each channel of the three channels of data is unidirectionally interleaved.

Step 204 (not shown): If a high-order modulation mode, such as 16QAM, is used, step 205 is performed, and then step 206 is performed; if QPSK modulation mode is used, step 206 is directly performed.

Step 205: Perform the 16QAM constellation rearrangement on the three channels of data processed in step 203. Here, for the QPSK modulation scheme, step 205 is transparent. That is to say, constellation rearrangement is not performed when the QPSK modulation method is employed. Since the actual implementation of 16QAM and QPSK modulation modes are possible, the 16QAM constellation rearrangement module must exist, only When using QPSK modulation, the module transmits transparently.

Step 206: Perform physical channel mapping on the three channels of data processed by the foregoing steps, and finally modulate the three channels of data to three carriers and send them to the receiving device.

Step 207 (not shown in the figure), after receiving the three-way data carried on the three carriers, the receiving device uses the multiplexing mode of the E-UCCH and the E-DCH to perform decoding.

Here, for the same user, because the data block size, the corresponding channel environment, and the allocated physical resources carried on different carriers may be different, the HARQ process used by the HARQ function block on each carrier may also be independent, so The E-UCCH information used for each data block transmission will be different, denoted as E-UCCH _A , E-UCCH _B , E-UCCH _C ; correspondingly, the number of E-UCCHs transmitted may also be different. According to the specific algorithm, it can be determined that it is set to leg ^ ^ENI B , ^ENI c.

The coding method of the HSUPA traffic transmission channel in the multi-carrier TDD system according to the implementation scheme of the present embodiment, because each carrier separately transmits different data blocks, and each has its own HARQ receiving function block, that is, data on each carrier. The transmissions are independent of each other. Therefore, the corresponding E-UCCH and E-DCH multiplexing modes are consistent with the prior art using the single-carrier HSUPA technology, that is, the E-UCCH carried on each carrier and the E carried on the carrier. - DCH data is correlated and multiplexed with E-DCH data on this carrier. The advantage of using the E-UCCH and E-DCH multiplexing modes is that the E-UCCH transmissions on the respective carriers are independent of each other and do not affect each other, which facilitates separate processing of each carrier data.

In summary, by using the implementation scheme of the embodiment, combining the three channels of data, and performing unified data scrambling and data interleaving, the data of each channel can be better randomized, and the data interleaving depth can be further expanded, thereby Obtain a certain time interleaving gain and frequency interleaving gain to better support the performance of the three-carrier TDD system. Similarly, this embodiment can also be extended to a TDD system employing an N carrier.

In this embodiment, the number of carriers is three. The TDD system is described as an example. Corresponding to FIG. 12, the implementation solution in this embodiment includes the following steps:

Step 301: The high-speed uplink data sending end device on the terminal side divides the data to be sent into three paths, and performs CRC adding, code block splitting, channel coding, physical layer HARQ function, data scrambling, and data interleaving respectively.

When the terminal-side transmitting device with multi-carrier transmitting capability uses multi-carrier to transmit data, in the same TTI, different carriers can perform scheduled transmission or non-scheduled transmission, and can also carry data of different transmission modes, that is, the terminal The side transmitting devices can perform scheduled transmission and non-scheduled transmission on different carriers in the same frame. For example, the terminal side transmitting end device may send unscheduled transmitted data on the carrier A, and transmit the scheduled transmission data on the carrier B and the carrier C, thereby transmitting the unscheduled transmission and the scheduled transmission simultaneously, and does not block each other. .

Step 302 (not shown), if a high-order modulation mode is used, such as a 16QAM modulation mode, step 303 is performed; if QPSK modulation mode is used, step 304 is directly performed.

Step 304: After performing the physical channel mapping processing on the three channels of data processed by the foregoing steps, respectively, modulating to three carriers and transmitting the signals to the receiving end device.

Step 305 (not shown in the figure), after receiving the three-way data carried on the three carriers, the receiving end device uses the multiplexing mode of the E-UCCH and the E-DCH to perform decoding.

Here, for the same user, because the data block size, the corresponding channel environment, and the allocated physical resources carried on different carriers may be different, the HARQ process used by the HARQ function block on each carrier may also be independent, so , the E-UCCH information used for each data block transmission will be different, denoted as E-UCCH _A , E-UCCH _B , E-UCCH _C ; correspondingly, the transmitted E-UCCH The number may also be different. According to the specific algorithm, it can be determined, set to ^£Λ ^, wish Β, Sa C. The coding method of the HSUPA traffic transmission channel in the multi-carrier TDD system according to the implementation scheme of the present embodiment, because each carrier separately transmits different data blocks, and each has its own HARQ receiving function block, that is, data on each carrier.

Embodiment 3:

In the third implementation scheme of the encoding method of the HSUPA traffic transmission channel in the multi-carrier TDD system provided by the embodiment of the present invention, N represents the number of carriers used for high-speed packet data transmission of the user terminal; The TDD system is described as an example. Corresponding to FIG. 13, the implementation solution in this embodiment includes the following steps:

Step 401: The high-speed uplink data sending end device on the terminal side performs the CRC addition, the code block splitting, the channel coding, the physical layer HARQ function, and the data scrambling prior processing on the data to be sent. Step 402: The processed data is first processed and the data is interleaved.

The processing method of data interleaving in step 402 in this embodiment may be as follows: Kind, but not limited to these three.

The processing method of the first type of woven data interleaving is as follows: the data processed by the step 401 is divided into three paths, and the length of each data is the same as the length of the data after the step 401 is processed first; Each channel of data carries out data interleaving of single channel data; then combines three channels of data in turn, and then performs overall interleaving; finally, it is divided into three channels of data, and the length of each channel of data and the length of data processed in step 401 before processing the same.

The processing method of the second type of data interleaving is as follows: the data processed by the step 401 is only interleaved and divided into three pieces of data, and the length of each line of data and the length of the data processed in step 401. the same.

The processing method of the third type of data interleaving is as follows: First, the data processed after the step 401 is interleaved as a whole, and then divided into three pieces of data, and the length of each line of data and the length of the data after the step 401 is processed first. The same; then each channel of the three-way data is unidirectionally interleaved.

Here, the step 404 is specifically as follows: the three channels of data processed in step 402 are not combined with each other, and the 16QAM constellation rearrangement is directly performed on each channel data.

Step 405: Perform physical channel mapping on the data processed by the foregoing steps, and then modulate to three carriers and send the data to the receiving end device.

In the implementation of this embodiment, since there is only one HARQ function block, the E-UCCH only needs to transmit one PID. Then, multiple carriers only need to transmit one E-UCCH information, and the corresponding E-UCCH number is ENI. In order to improve the E-UCCH transmission performance, multiple E-UCCHs are distributed to each carrier for transmission, thereby realizing E-UCCH. The frequency diversity is transmitted, and the E-UCCH is combined at the receiving end device to obtain the frequency diversity gain.
