S5：Data are sent in second service sub-band.
The embodiment of the invention provides a kind of data transmission method for uplink can pass through jump when sending frame is that frequency hopping sends frame
Frequency switches the service sub-band being used to send data, can be improved data transmit in the preferable service sub-band of transmission quality it is general
Rate.
Wherein, the service sub-band on any available all frequency domains in this cell necessarily belongs to the first sets of subbands or
Two sets of subbands.In the complexity in order to reduce no business terminal monitoring or paging information etc., by the industry in the second sets of subbands
The transmission frame of business subband is divided into non-hopping and sends frame, is sent when frame sends data by non-hopping without frequency hopping.
Wherein, by the service sub-band in second sets of subbands according to frequency size serial number from low to high, specifically
Including：Each service sub-band is a continuous frequency band, is carried out according to the frequency in the frequency band of any two service sub-band
Compare, if the optional frequency in the service sub-band 1 in described two service sub-bands is both greater than any frequency in service sub-band 2
Rate, then the frequency of service sub-band 1 is greater than the frequency of service sub-band 2, according to the rule by all service sub-bands according to frequency size
It is ranked up, and is from low to high that each service sub-band is numbered according to frequency.
Preferably, the step S4 is specifically included：
The number of second service sub-band is determined according to the following formula：
When working as i=2k, k=0,1 ...,
When working as i=2k+1, k=0,1 ...,

To terminal.Specifically, the configuration information is sent to by terminal by broadcast or dedicated signaling using bit map.
The terminal that the service sub-band that frame information is sent in occupancy second sets of subbands will be sent in advance, packet
It includes：Periodic bit bitmap is first passed through in advance, and the transmission frame information is sent to the service sub-band occupied in second sets of subbands
Terminal.
In addition, terminal can distribute service sub-band to base station requests, and terminal can be sent out to base station when terminal needs to send data
Send the service request for requested service subband；Therefore, further include before the S1：Receive the service request that terminal is sent.
It should be noted that：When having selected the second service sub-band, and when currently transmitted frame is that frequency hopping sends frame, due to number
The difference of the serial number of currently transmitted frame during according to transmission can make the number of the second service sub-band obtained different, and then make
It is actually subjected to the service sub-band occupied when sending data to change with the difference for sending frame, realizes frequency hopping, can be kept away by frequency hopping
Exempt from data to transmit in a lower service sub-band of transmission quality always.
It should be noted that：In order to obtain preferable frequency selection scheduling gain or frequency selectivity diversity gain, draw
When dividing the first sets of subbands and the second sets of subbands, two sets of subbands should be made to evenly spread to all available bandwidths as far as possible.
It should be noted that：It can be according to following principle when selecting sets of subbands：For low velocity or big data quantity industry
The terminal of business selects the first sets of subbands, selects the second sets of subbands for the terminal of high speed or small data quantity business,
In, the terminal of low velocity and the terminal of high speed can be judged by preset threshold speed, when the speed of terminal is less than in advance
If threshold speed when, then the terminal be low velocity terminal, when the speed of terminal be not less than preset threshold speed when, then should
Terminal is the terminal of high speed.The terminal of large-data operation and the terminal of small data quantity business can pass through preset data volume
Threshold value judges, when the data volume business of terminal is less than preset data-quantity threshold, then the terminal is small data quantity business
Terminal, when the data volume business of terminal is not less than preset data-quantity threshold, then the terminal is the terminal of large-data operation.
