The frequency band of the system is divided into multiple 200 kHz frequency points by the network, and the terminals communicate at different frequency points. At the same time, in order to allow multiple terminals to share resources of one frequency point, each frequency point is in time. It is divided into 8 time slots of about 0.577 milliseconds in length (that is, the period of each time slot is 8x 0.577 « 4.6 milliseconds). Each time slot of GSM can carry one traffic channel (TCH, Traffic Channel), so up to eight full-rate voice services can be provided at one frequency. The eight consecutive time slots are called a TDMA frame, and the information sent in each time slot is called a "burst".

In GPRS, one PDCH can be carried on each time slot, one PDCH can be shared by multiple terminals, and one terminal can also be assigned multiple PDCHs. In addition, GPRS introduces a radio block. The burst with the same slot number on four consecutive TDMA frames is called a radio block. As shown in Figure 1, a TDMA frame is provided.

The amount of computation of the device, which in turn reduces the power consumption of the network-side device.

 For the network side device, the network side device may be specifically configured to perform a method corresponding to the method provided in the embodiment shown in FIG. 4, as shown in FIG. 5a, as follows.

 5 01. The network side device determines, according to a preset rule, a location of the X radio blocks of the first data that are sent by the bearer terminal to the network side device in a multiframe, where X is an integer, and 1 2 xm >X ≥2.

 The multiframe is composed of 5 2 xm frames, and the multiframe includes 12 2mm of the radio blocks, and m is a positive integer. For example, m= 2.

 Further, the data transmission method further includes:

 The network side device sends the preset rule to the terminal; and/or the network side device sends the configuration information of the multiframe to the terminal, where the configuration information of the multiframe includes the composition The number of frames of the multiframe.

 Specifically, the multiframe is composed of 52 xm frames, and m is a positive integer. For example, m= 2. The preset rule may include:

 The X radio blocks are consecutive radio blocks, and the X radio blocks are disposed at the front or the rear of all the radio blocks except the X radio blocks in the one multiframe;

 Or,

 The X radio blocks are divided into X/n radio block groups, and each of the radio block groups includes n radio blocks consecutively arranged in the one multiframe, and any two adjacent radio blocks are adjacent. The group passes at least one other radio block interval except the X radio blocks in the one multiframe, where X/n is a positive integer.

 The configuration of the multi-frame structure is usually configured by the network side device on the network side. The specific configuration information may be broadcast in the cell through the system message, or may be notified to the terminal through dedicated signaling when the channel is allocated. The network side device can configure the number of frames in each multiframe according to the coverage requirement of the data sent by itself, so as to implement flexible configuration of network data transmission signal coverage requirements.

For the uplink data, the network side device is configured with the preset rule in advance, so that the network side device can directly obtain the data sent by the terminal to the network side device in the X radio blocks in a multiframe according to the preset rule. Referring to the method provided in the embodiment shown in FIG. 4, details are not described herein again. The network side device can directly listen to X radio blocks in a multiframe according to a preset rule by transmitting the data to the network side device on the X radio blocks in a multiframe according to a preset rule, and The data acquisition terminal carried on the X radio blocks in the one multiframe is sent to the network side device The data avoids the network side device to separately demodulate or decode each received wireless block, thereby reducing the amount of computational network side devices of the network side device, thereby reducing the power consumption of the network side device.

 Specifically, in the existing GPRS technology, the manner of dividing the radio block is as shown in FIG. 6. One time slot (PDCH) is repeated in time with 52 TDMA frames, and each period is called a 52 multiframe. There are 12 radio blocks (Block 0 to Block 11) for transmitting data and high layer signaling, and two T frames (X) for transmitting timing advance information, two I frames (Idle frame, idle). Frame) does not send information, but is used for terminal neighbor measurement. Figure 6 shows the TDMA frame number, which takes values from 0 to 2715647, so starting from frame number 0, the frame number of the first 51 multiframe ranges from 0 to 51, and the frame number of the second 51 multiframe. The range is 52 to 103, .... The frame number of the next frame of the frame whose frame number is 2715647 is wrapped back to 0.

 Taking data transmission in GPRS as an example, the data transmission and reception in the above embodiments are all completed by establishing a Temporary Block Flow (TBF) through a radio block, and one TBF is used to complete several user data (such as a click). The transmission of data generated by a link on a web page.

According to the direction of data transmission, the TBF can be further divided into an uplink TBF (transmitting data from the terminal to the network side device) and a downlink TBF (transmitting data from the network side device to the terminal). The uplink TBF and the downlink TBF are generally present between the terminal performing the packet service and the network side device. Both the upstream and downstream TBFs are identified by a field in the header of the data called Temporary Flow Identity (TFI). When establishing a downlink TBF, the network side device allocates one or more downlink PDCHs to the terminal, and allocates one TF I to each PDCH. The terminal then monitors the downlink radio block on each PDCH, and if the TFI value in the radio block header is equal to the TFI assigned to itself by the network on the PDCH, then the radio block is considered to be addressed to itself. When an uplink TBF is established, on each of the allocated uplink PDCHs, the network side device allocates a TFI to the terminal and allocates an Uplink State Flag (USF). The terminal then monitors the downlink radio block on the downlink PDCH corresponding to each uplink PDCH, if the USF value in the radio block (Bn) header is equal to the network side device assigning itself to the corresponding PDCH. The USF considers that the network side device is scheduling itself to send uplink data, and the terminal can send data on the uplink PDCH in the next radio block (Bn+1) period. The specific process of data transmission by establishing a temporary block flow is a prior art, and details are not described herein again.

 Specifically, an embodiment of the present invention is described with reference to the structure of the multiframe provided in FIG. 7-1Q, wherein the radio block Cx represents X radio blocks carrying data required for signal coverage enhancement in a multiframe, and a radio block Bx represents Other radio blocks carrying data that does not require signal coverage enhancement in one multiframe.

 The preset rule includes: the X radio blocks are divided into X/n radio block groups, and each of the radio block groups includes n radio blocks that are consecutively disposed in the one multiframe, and are adjacent to each other. Between the two radio block groups, at least one other radio block interval except the X radio blocks in the one multiframe, where X/n is a positive integer, specifically refer to FIG. The embodiment of the present invention provides a structure of a 104 multiframe, which transmits data requiring enhanced coverage by 16 radio blocks Cx, where X = 16, n=8, k=3; B0-B7 is used for the third data. The transmission, C0-C15 is used to send the first data, at this time in the 104 multiframe through (C0-C15) 16 radio blocks carrying the required signal coverage enhanced data; through (B0-B7) 8 radio blocks bear not The signal coverage enhanced data is required, and specifically, the channel-coded first data in the CQ is repeatedly transmitted through C1-C15.

 The first data that is channel-coded in the CQ repeatedly transmitted through C1-C15 is one of the less efficient ones in the forward error correction technique, and can be replaced by other more effective forward error correction techniques, such as using the first data. A block code or a convolutional code or a turbo code (turbo code) is channel coded at a very low code rate (1/16 of an existing system) to form a second data, and then a second The data is divided into 16 pieces and carried on C0-C15 in order. B0-B7 is dispersed in 104 multiframes, so that even in the case of scheduling a new terminal, the network can still schedule traditional terminals that do not need to cover enhanced data at a higher frequency (can be implemented every 3 radio block periods) Schedule once).

Specifically, the transmission to the USF can be implemented through C0-C15. As with the existing 52 multiframe structure, the uplink scheduling and downlink data transmission are decoupled: When each radio block in C0-C15 carries the same data content, each radio block in C0-C15 carries USF. The USF received by the terminal is used to schedule the uplink transmission of the terminal. When the block header of each radio block in C0-C15 carries the same USF, the data content of each radio block in C0-C15 may not be repeated, and is used for transmitting data to the terminal. The USF repeatedly transmitted in the block header of each radio block by C0-C15 downlink in the 104 multiframe is used to schedule the data content of the uplink C0-C15 carried in the next 104 multiframe.

 Therefore, for the downlink data, the terminal may acquire the location of the radio blocks C0-C15 carrying the data requiring the signal coverage enhancement in the multiframe according to the preset rule; when the terminal listens to all the radio blocks C0 that carry the signal coverage enhanced data. After C15, the terminal only needs to combine the data contents carried by the downlink C0-C15 for demodulation and decoding in each 104 multiframe, and does not need to acquire the contents of other radio blocks. For uplink scheduling, the USF sent to the terminal can only transmit repeatedly through C0-C15. Therefore, in each 104 multiframe, only the USF in the downstream C0-C15 header needs to be combined for demodulation and decoding. For the uplink data, when the network side device schedules the data that needs to be enhanced by the signal coverage in the downlink C0-C15, the network side device only needs to combine the data contents carried by the uplink C0-C15 for demodulation in each 104 multiframe. , decoding can be. If the network side device schedules data that does not require signal coverage enhancement on the downlink C0-C15, the data content in B0-B7 is obtained by using the prior art. In summary, in the 104 multiframe structure, since the receiving device can determine the location of the radio blocks C0-C15 carrying the data requiring enhanced coverage according to the preset rule, thereby avoiding the data receiving end for each received wireless The block attempts to demodulate or decode it separately, thereby reducing the amount of computation at the data data receiving end.

 Or the preset rule includes: the X radio blocks are consecutive radio blocks, and the X radio blocks are set in all one radio blocks except the X radio blocks in the one multiframe. For the front or rear part, as shown in Fig. 8, a structure of 104 multiframes is provided, X=16, k=3, B0-B7 continuous 4 non-歹' J, C0-C15 continuous 4 non-歹' J , And C0-C15 is located at the rear of B0-B7. Since the combination, demodulation and decoding processing can only be performed when C0-C15 is all monitored by the terminal, the configuration of Fig. 7 can shorten the terminal acquisition C0 with respect to the configuration of Fig. 6. - The time of the data content carried by the C15.

Optionally, as shown in FIG. 9, a structure of a 104 multiframe is provided, where X=20, n=4, and k=3; in view of the need for the terminal to enhance the signal coverage, the need for signal coverage enhancement is required. The data is configured with more radio blocks, X > 16. At this time, the multiframe structure shown in FIG. 9 can be used, and the radio blocks included are B0-B3 and C0-C19.

 Further, when more radio block bearers are required to signal enhanced data,

For the terminal, the data transmission method further includes: the terminal receiving the configuration information of the multi-frame sent by the network side device, where the configuration information of the multi-frame includes the number of frames constituting the multi-frame.
