The cell information of the second serving cell is exemplified by the available channel resource, the available channel resource is 10, and the sending module 201 sends the information of the available channel resource 10 to the processing module 102.

Assuming that the available channel resource of the first serving cell is 5, the processing module 102 divides the service data according to the information of 'the first serving cell available channel resource is 5' and the 'second serving cell's available channel resource is 10', from 30 data. In the packet, p1, p2, ..., p10, and p21, p22, ..., p30 are selected as the second data block, and the remaining p11, p12, ..., p20 are determined as the first data block, and the transmitting module 103 is p11, p12, ..., p20 is sent to the mobile phone 1, and p1, p2, ..., p10, and p21, p22, ..., p30 are sent to the receiving module 202, which transmits p1, p2, ..., p10, and p21, p22, ..., P30 is sent to the mobile phone 1, and the mobile phone 1 assembles p11, p12, ..., p20, p1, p2, ..., p10 and p21, p22, ..., p30 to obtain complete service data;

The data transmission method based on the multi-base station multi-carrier is introduced from the first base station side, and the first base station can divide the service data in multiple manners, and then distribute the part of the service data that is obtained by the first base station and the second base station respectively. For the user terminal, the following are introduced separately:

1. The first base station divides the service data according to the cell information of the first serving cell and the cell information of the second serving cell:

Referring to FIG. 4, an embodiment of a data transmission method based on multiple base stations and multiple carriers in an embodiment of the present invention includes:

401. The first base station acquires service data according to the service request sent by the user terminal.

In this embodiment, when the user terminal initiates a service request, the first base station may acquire service data according to the service request, and store the service data in the data queue. For example, the service data is composed of 10 data packets in the data queue, and the transmission sequence numbers are P1, P2, ..., P10.

402. The first base station acquires information that is sent by the second base station by using an information channel, where the information includes cell information of the second serving cell.

Specifically, an information channel is configured between the first base station and the second base station, and when the second base station sends information through the information channel, the first base station can receive the information. The information includes the cell information of the second serving cell, where the second serving cell corresponds to the second base station, and the cell information includes the available channel resources of the cell, the number of cell users or the types of available channel resources, and may also include other information, where Not limited.

The information channel is carried on a wired network and can transmit service information and control information. The wired network is a signal transmission medium such as an optical fiber or a cable.

It should be noted that the frequency band or frequency used by the second base station and the first base station for transmitting service data are different, that is, the frequency bands or frequency points of the first serving cell and the second serving cell are different. The second base station may be a base station whose distance from the first base station is less than a preset distance, or may be a base station whose network cross-covering coverage with the first base station is greater than a preset range, which is not limited herein.

403. The first base station divides the service data into the first data block and the second data block according to the cell information of the first serving cell and the cell information of the second serving cell, and the transmission sequence number of the first data block and the second data block. Follow the same numbering rules;

For example, the service data size is 60,000 bits and consists of 30 data packets, such as p1, p2, ..., P30, each data packet size is 2000 bits, the available channel resource of the first serving cell is 5, and 10000 bits can be carried in one available time, and the available channel resource of the second serving cell is 10, and can carry 20,000 bits in one available time. The first base station may allocate service data according to the proportion of available channel resources, such as (60000/15)×10=40000bits, and select p1, p2, ..., p10, and p21, p22, ..., p30 from 30 data packets as The second data block determines the remaining p11, p12, ..., p20 as the first data block. The sequence numbers of the first data block and the second data block follow the same numbering rule, and the transmission sequence numbers of the data packets in the first data block and the second data block are connected to each other to form a complete and continuous sequence number queue.

It can be understood that the number of data packets, the data packet object, and the data packet allocation ratio can be adjusted according to actual conditions, which is not limited herein.

404. The first base station sends the transmission sequence number of the first data block and the first data block to the user terminal, and sends the transmission sequence number of the second data block and the second data block to the second base station by using the information channel, so that The two base stations transmit the transmission sequence numbers of the second data block and the second data block to the user terminal.

It can be understood that, since the transmission sequence numbers of the data packets in the first data block and the second data block follow the same numbering rule and are continuous, after the user terminal receives the first data block and the second data block respectively, the transmission sequence number may be The first data block and the second data block are assembled into one complete business data.

In this embodiment, the first base station may divide the service data according to the cell information of the first serving cell and the cell information of the second serving cell, and one service data may be divided into the first data block and the second data block, by the first base station and The second base station is separately delivered, which improves the data transmission efficiency of the communication system.

2. The first base station divides the service data according to the amount of data that can be processed by the second base station:

Referring to FIG. 5, another embodiment of a data transmission method based on multiple base stations and multiple carriers in an embodiment of the present invention includes:

501. The first base station acquires service data according to a service request sent by the user terminal.

502. The first base station acquires information that is sent by the second base station by using an information channel, where the information includes a quantity of data that can be processed.

Specifically, an information channel is configured between the first base station and the second base station, and when the second base station passes the information When the channel transmits information, the first base station can receive the information. The information includes the amount of data that can be processed, and the amount of data that can be processed refers to the number of bits of the service data of the second base station to the first application. For example, the number of bits of the service data that the second base station applies to the first base station is 10000 bits.

It should be noted that the frequency bands used by the second base station and the first base station to transmit service data are different, that is, the frequency bands or frequency points of the first serving cell and the second serving cell are different. The second base station may be a base station whose distance from the first base station is less than a preset distance, or may be a base station whose network cross-covering coverage with the first base station is greater than a preset range, which is not limited herein.

503. The first base station determines, according to the amount of data that can be processed, the second data block, and determines, in the service data, part of the service data except the second data block as the first data block.

For example, the service data size is 60,000 bits, consisting of 30 data packets, such as p1, p2, ..., p30, each packet size is 2000 bits, the number of bits that can handle data is 10000 bits, and the first base station can be from 30. The service data of the 10000 bits is selected as the second data block, for example, p26, p27, ..., p30, and the first base station uses the remaining p1, p2, ..., p25 as the first data block.

It can be understood that the first base station can also send less than 10000 bits of service data to the second base station. For example, the first base station only sends three data packets p28, p29, and p30 to the user terminal, and the number of allocated data packets can be based on actual conditions. The situation adjustment is not limited here.

504. The first base station sends the transmission sequence number of the first data block and the first data block to the user terminal, and sends the transmission sequence number of the second data block and the second data block to the second base station by using the information channel, so that The two base stations transmit the transmission sequence numbers of the second data block and the second data block to the user terminal.

When the information sent by the second base station to the first base station includes both the amount of data that can be processed by the second base station and the cell information of the second serving cell, the first base station may select one of the two, or select the second according to the two parameters. The amount of data that can be carried by the base station is divided into service data, which is not limited herein.

For example, when the service data size requested by the second base station is 10000 bits, and the second serving cell has 10 available channel resources, the first base station may divide the service data according to available channel resources of the second serving cell, or from the service data. Select a packet of no more than 10000 bits and the transmission sequence number of the packet.

It should be noted that the first base station may also divide the service data according to other information, such as the status of the information channel, which is not limited herein.
