Feedback, by the state report of the downlink valid data received to base station.
Wherein, the default bag is system total bytes number and the ratio of downlink valid data length and the difference in SR cycles；Institute
Preset byte is stated as system total bytes number and the product of downlink valid data length and the difference in SR cycles.
Default bag X or preset byte Y is set, when terminal receive downlink data for X bags or Y bytes when to base station transmission the
Two RLC are fed back；
For the separated system of uplink and downlink business, the downlink byte number of system is fixed, if byte number is Z, if channel conditions
Relatively severe, uplink and downlink is transmitted according to minimum MCS grades, sets the corresponding data block length of row MCS grades as P, it is assumed that in transmission
Between there is no a MCS level adjustments, and the 2nd RLC feedbacks can pass in a radio frames.X is set to cause effective apart from downlink
Data transmission deadline point biased forwards about M or M/2 radio frames have the first RLC of bag feedbacks, further according to byte number Z and
MCS grades set the value of X, wherein, X=Z/P-M or X=Z/P-M/2 is set.
The setting of Y value assume that channel quality is slightly good, for example be transmitted with medium MCS grades on the lower side, set Y=Z-M*
P or Y=Z-M*P/2.
In order to prevent when terminal is received described in the default bag or the preset byte downlink valid data and progress
After 2nd RLC feedbacks, and receive the preset byte successively or the default bag downlink valid data continue the
Therefore the wasting of resources caused by two RLC are fed back, sets Status Disable timer so that terminal receives the default bag or institute
After stating preset byte downlink valid data and carrying out the 2nd RLC feedbacks, in the Status Disable timer duration of setting
Interior and while receiving the preset byte or the default bag downlink valid data, feeds back without the 2nd RLC.So
The setting of Status Disable timer is also required to the M radio frames that can deviate downlink valid data end of transmission or M/2 wireless
Frame sets product of the timer duration for the default bag number and wireless frame length, i.e. timer duration=X*25ms.
The embodiment of the present invention is by setting default bag and predetermined word joint number, when terminal receives default bag or preset byte
During downlink valid data, progress the 2nd RLC feedbacks, so that the first RLC feedbacks and upstream data are using finally
The SR resources applied in one the 2nd RLC feedback procedure transmit upstream data to base station, reduce business to a certain extent
Time delay improves the timeliness of system.And by setting Status Disable timer so that terminal receive it is described it is default bag or
Preset byte downlink valid data and after carrying out the 2nd RLC feedback, in the Status Disable timer of setting
It is fed back when receiving the preset byte or the default bag downlink valid data in long again without the 2nd RLC, from
And system resource is saved.
