Specific embodiment
Currently, the power consumption of femto cell is usually larger, causes in order to offset the influence that signal is transmitted in transmission channel decline
The femto cell design difficulty and cost are increase accordingly.
In view of the above-mentioned problems, the method can be to be passed the embodiment provides a kind of data transmission method
When the rate of transmission of data is higher than the first scheduled rate, the length of the data to be transmitted is judged, and according to judging result,
The maximum length value closest to the transmission block is set by the length value of the transmission block of the data to be transmitted or subcode block, because
This can reduce the miniature power consumption in the case where guaranteeing that terminal has identical demodulation performance.
To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment explain in detail.
As shown in Figure 1, the method may include following steps the embodiment of the invention provides a kind of data transmission method
It is rapid:
Step 11, judge whether the rate of data to be transmitted is higher than the first scheduled rate.
In specific implementation, the femto cell, must be to data to be transmitted before sending data to corresponding terminal
Carry out respective handling.Specifically, the femto cell adds verification data after the data to be transmitted, constitutes transmission block.Institute
The rate of the data to be transmitted can be transmitted according to present channel bandwidth estimation by stating femto cell, and then according to described to be transmitted
The data modulation is arranged in the rate of data, is finally that the terminal distribution is other according to the modulation system of the data
Dispatch resource.The terminal, can be in corresponding resource block after the above-mentioned scheduling resource for receiving the femto cell distribution
On position, the data are received using demodulation mode corresponding with the modulation system.
In specific implementation, the modulation system of the value Yu the data of first scheduled rate.For example, described first is pre-
If rate can proceed as follows setting: when modulation system is that quadrature phase shift keying is modulated, first scheduled rate is
15Mbps；When modulation system is the quadrature amplitude modulation comprising 16 kinds of symbols, first scheduled rate is 30.10Mbps；
When modulation system is the quadrature amplitude modulation comprising 64 kinds of symbols, first scheduled rate is 75Mbps.
It should be noted that in specific implementation, first scheduled rate can also be adjusted according to other factors, than
Such as, first scheduled rate can be adjusted according to the bandwidth of present channel, herein with no restriction, as long as according to described
When first scheduled rate executes technical solution of the present invention, the power of the femto cell can be reduced.
It should be noted that in an embodiment of the present invention, the terminal can include but is not limited to mobile phone, notebook,
The equipment such as tablet computer and vehicle-mounted computer.
Step 12 is executed when the rate for determining data to be transmitted is less than or equal to the first scheduled rate, it is no to then follow the steps 13.
Step 12, the data are transmitted according to the first dispatching cycle.
In specific implementation, it is generally the case that regardless of the data rate to be transmitted, the femto cell is all pressed
The data are transmitted according to identical dispatching cycle.In an embodiment of the present invention, in order to small in the rate of the data to be transmitted
When being equal to the first scheduled rate, increase the interval time of the femto cell transmission data, first scheduling can be set
Period was greater than for the second dispatching cycle.Wherein, second dispatching cycle is that the transmission rate of the data to be transmitted is higher than first
Dispatching cycle when scheduled rate.After dispatching cycle increases, because the terminal quantity of femto cell original scheduling is constant, therefore can
To increase the scheduling time of the femto cell scheduling same number terminal, the femto cell transmission data are also increased
The power of the femto cell is effectively reduced in interval time.
For example, the femto cell dispatches 10 ends when the rate of the data to be transmitted is higher than the first scheduled rate
Second dispatching cycle at end is 1ms.When the rate of the data to be transmitted is less than or equal to the first scheduled rate, it is arranged described the
One dispatching cycle was 4ms.Relative to the second dispatching cycle, the femto cell is less than or equal in the rate of the data to be transmitted
When the first scheduled rate, the scheduling time of 10 terminals is increased, therefore 10 terminal transmission datas of the femto cell
Interval time increase.In the case where transmitting same data volume, relative to be scheduling to dispatching cycle the second dispatching cycle
Situation, the lower power consumption of the femto cell.
Step 13, judge whether the sum of the length value of the data to be transmitted and the length value of verification data are less than transmission block
Maximum length value.
Verification data are added in the base station after the data, constitute transmission block.If the length value of the transmission block is less than
The maximum length value of the transmission block, then after the length value of the transmission block is arranged, directly by the transport block transmission to correspondence
Terminal.If the length value of the transmission block is more than or equal to the maximum length value of the transmission block, first by the transmission block
Code block segmentation is carried out, obtain several subcode blocks, and the length value of each subcode block is set, and will be sent out after subcode block cascade
It send to corresponding terminal.
When the sum of the length value of the data to be transmitted and the length value of verification data are less than the maximum length value of transmission block
When, step 14 is executed, otherwise executes step 15.
Step 14, according to the scheduling resource currently distributed, the length value of the transmission block of the data to be transmitted is set to pass
Closest to the maximum length value of the transmission block in defeated piece of look-up table, and according to the corresponding letter of the length value of set transmission block
Data described in road bandwidth for transmission.
Wherein, the length value of set transmission block is less than the maximum length value of the transmission block.
In specific implementation, as previously mentioned, the modulation system of the i.e. described data of scheduling resource currently distributed.It is passing
In defeated piece of look-up table, the modulation system and transmitting block index I of the dataTBSIt is unique corresponding.That is, every kind of modulation system
A unique corresponding ITBS.After the femto cell is the modulation system of data described in the terminal distribution, according to the data
Modulation system selects the length value closest to the maximum length value of the transmission block, as the biography from transmission block look-up table
Defeated piece of length value, and then using the corresponding resource block quantity of the length value of the selected transmission block as shared by present channel
Resource block quantity, the femto cell transmit the number according to the accessed occupied resource block quantity of present channel
According to.
For example, in the fractional transmission block look-up table shown in table 1, NPRBIndicate occupied when present channel is PDSH channel
Resource block quantity, it is assumed that the corresponding I of the modulation system of the dataTBSValue be 17, the resource that present channel bandwidth is included
The quantity of block is 18, and the length value of the verification data is 24bit, for the maximum length value of the transmission block is 6144bit.
In order to reduce the power consumption of the femto cell, the length value that the transmission block can be set is the maximum of the closest transmission block
Length value, i.e., the length value of the described transmission block are 5736bit.Corresponding N at this timePRBValue be 16.That is, described miniature
The transport block length of the data is set 5736bit by base station, and is transmitted by 16 resource blocks.
Table 1
Step 15, according to the scheduling resource currently distributed, the length value of the subcode block of the data to be transmitted is set to pass
Closest to the maximum length value of the transmission block in defeated piece of look-up table, and according to the corresponding letter of length value of set subcode block
Data described in road bandwidth for transmission.
Wherein, the length value of set subcode block is less than the maximum length value of the transmission block.
As previously mentioned, when the sum of the length value of data to be transmitted and the length value of verification data are more than or equal to transmission block most
When greatly enhancing angle value, the transmission block is first subjected to code block segmentation, obtains several subcode blocks.At this point, the base station can basis
The scheduling resource currently distributed, be arranged the subcode block length value be transmission block look-up table in closest to the transmission block most
Angle value is greatly enhanced, and the data are transmitted according to the corresponding channel width of the length value of set subcode block.Specific setting method
It is referred to the above-mentioned description in step 14, details are not described herein again.
As shown in the above, the data transmission method provided in the embodiment of the present invention passes through the speed in data to be transmitted
When rate is higher than the first scheduled rate, the length of the data to be transmitted is judged, and according to judging result, it will be described to be passed
