Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, do not limit the present invention.
The present invention distributes control channel in order, remaining control channel bandwidth is used for transmitting data, thus improves the utilance of upstream bandwidth.
In the WiMAX system of time division duplex (TDD), typical frame structure (for the whole subchannel networking of 10M) can see Fig. 1, wherein, ranging region (ranging region) takies 6 sub-channels, and feedback areas (ACK region), fast feedback region (FFB region) take remaining 29 sub-channels; Wherein, ranging region specifies according to 802.16e, can period allocated; ACK region distributes relevant with descending HARQ subburst, every 2 descending HARQ subburst need 1 sub-channels, but at first dispatching uplink, to arrange travelling carriage (MS) feedback delay be in the WiMAX system of 1 frame, the descending HARQ subbusrt number of actual schedule can not be learnt, need to make certain anticipation (when making anticipation, the ACK region size of anticipation just limits the descending maximum HARQ subburst number that can dispatch); FFB region is relevant to application FFB situation, needs N frame in advance to distribute control channel.Generally speaking, the situation of local channel free time may be there is in control channel according to the number of users of the configuration of system, enable, the actual access of correlation function, technical scheme of the present invention can make every frame according to current control channel behaviour in service, the control channel bandwidth of free time is used for transmitting data, thus improves better upload bandwidth utilisation.
Data transmission method provided by the invention comprises:
Step one, determine the size of present frame feedback areas;
Step 2, distribute control channel according to the size of the feedback areas determined, and utilize remaining control channel to transmit data.
Wherein, distribute the process of control channel as shown in Figure 2, this process comprises:
Step 201, judge present frame the need of distribution ranging region (ranging region), as need distribute, then perform step 202, otherwise perform step 203;
The need of distributing ranging region and needing the size of distributing all can learn from configuration;
Step 202, distribution present frame ranging region;
Step 203, determine the size of present frame feedback areas (ACK region);
Step 204, distribute present frame feedback areas according to the size of feedback areas;
Step 205, determine present frame fast feedback region (FFB region) size;
Determine with existing, the mode of present frame FFB region size determines that mode is identical, do not describe in detail at this;
Step 206, to distribute according to fast feedback region (FFB region) size.
Region behind ranging region in removing control area, feedback areas and FFB region can be used as remaining control channel transmission data.
In above-mentioned steps 203, the size of present frame feedback areas, when downstream feedback time delay (DL ACKDelay) is set to > 1, directly can know the number of HARQ descending (DL) data burst (Subburst) from the descending distribution of previous frame, thus know the size in present frame ACK region; When downstream feedback time delay is set to 1 frame, if first dispatching downlink, then also can know the number of HARQ DL Subburst from descending distribution; Otherwise can not learn the number accurately of HARQ DL Subburst, then adopt the mode of anticipation to determine the size of present frame feedback areas, this anticipation process comprises:
Step 31, draw ACK Region magnitude range and initial size according to configuration and the number of users of the enable HARQ of system access;
ACK Region magnitude range [minACK, maxACK] is obtained according to band width configuration;
Arrange initial ACK Region size initACK, and adjust when enable HARQ user accesses/exits, the object of adjustment allows new access customer can use HARQ, meets service quality (Qos);
The ACK occupancy of step 32, statistical history, when ACK region size is not enough, increases ACK region size, when ACK region size is idle, reduces ACK region size.
This step 32 comprises:
Step 321, to upgrade in statistical information according to previous frame subburst number and transmitted subburst number TransNum;
Step 322, judge whether previous frame subburst number reaches time slot (slot) support number thresholding, if so, then perform step 323, otherwise, then perform step 324;
This slot s lot support number thresholding is the subburst number that current ACK region supports;
Step 323, increase expire slot continuously dispatches frame number FullNum; Turn to step 325;
Step 324, empty continuously completely slot and dispatch frame number FullNum, turn to step 326;
Step 325, judgement expire slot scheduling frame number FullNum continuously and whether arrive rising threshold value FullUpthro, if not, perform step 326, if so, execution step 328;
Step 326, judge whether to arrive measurement period StatPeriod, if not, then directly use last feedback areas size to be current feedback area size CurrACKNum, and terminate, if so, execution step 327;
Step 327, whether adjust ACK Region size, if so, perform step 328, otherwise, perform step 329;
Step 328, adjust ACK Region size being no more than under ACK Region magnitude range prerequisite, specifically, what continuous completely slot scheduling caused is adjusted to: increase ACK region size FullUpStep (flow that this measure causes to prevent ACK region not enough is limited), what cycle statistics caused is adjusted to: ACK region occupancy arrives not enough thresholding UpThro then increases UpStep, arrive idle thresholding DownThro and then reduce DownStep, turn to step 329;
Step 329, empty statistical information; Terminate.
Below with the whole subchannel of 10M, the ranging cycle is that every frame is assigned as example, and determine the size of ACK region, this process comprises:
Step 1, obtain the magnitude range [0,29] of ACK Region;
Step 2, suppose that InitACK is 1, when there being enable HARQ user to enter, if current enable HARQ number of users is 1, directly adjustment CurrACKNum is 2, more users and CurrACKNum is adjusted to 3 less than 3;
Step 3, to dispatch by full slot rising threshold value and measurement period adjustment feedback areas respectively lift one such as under, if CurrACKNum is 4:
A) previous frame scheduling burst number is 8 (to set FullNum to be 1 as 19, FullUpthro is 20, FullUpStep), full slot scheduling, and meet rising threshold value at present, then increasing CurrACKNum is 5;
B) (set StatPeriod as 200, UpThro is (CurrACKNum-0.5)/CurrACKNum, DownThro is (CurrACKNum-1.5)/CurrACKNum, UpStep and DownStep is 1), measurement period is arrived if current, and TransNum is 1400 ~ 1499, then > UpThro, increase CurrACKNum to 5, if TransNum is < 1000, then < Downthro, then reduce CurrACKNum to 3.
