Description
Technical field
The present invention relates to the business data processing method and the base station of the scheduling of resource of mobile comm message base station, particularly a kind of semi-continuous scheduling.
Background technology
LTE (Long Term Evolution, Long Term Evolution) system is based on the system of scheduling, carries data by the base station assigns running time-frequency resource, and terminal receives or send data according to the control channel information of base station.
Simultaneously, the LTE system has also introduced the semi-persistent scheduling mechanism of using at particular traffic data bag (as the voice packets of VoIP business), wherein, the allocation of packets that specific transactions is given in the base station is running time-frequency resource and specify the constant transmissions form fixedly, and the packet of this specific transactions sends with appointment constant transmissions form in the allocated resource position, promptly on the predefine resource, send, need not dispatch in the predefine mode.The difference of semi-continuous scheduling and dynamic dispatching is that initial HARQ transmission does not take the control channel resource, can save the control signaling consumption.
The distribution of semi-continuous scheduling cycle and resource is decided by the business data packet characteristics that are scheduled, and this business data packet has the fixing and relatively-stationary characteristics of packet size of packet arrival cycle.
The VoIP voice packets that with speed is 12.2kbit/s is an example, and its coding back packet size is 40byte substantially, and the packet arrival cycle is fixed as 20ms.Therefore, as long as the base station pre-dispense cycle is the resource that 20ms can transmit the 40byte data, can when not taking the dispatch resource, initial HARQ transmission guarantee the timely transmission of VoIP voice packets.
The business data packet of carrying out semi-continuous scheduling has the different cycles characteristic separately, and the arrival cycle that has is the integral multiple of 10ms, and as the VoIP business, the cycle is 20ms.The arrival cycle that has for the integral multiple of 5ms or 10ms, as some video traffic, does not carry out with the speed of per second 15 (64ms cycle) frame or 30 frames (32ms cycle).
In the prior art, in time transmit for guaranteeing business datum, the half-persistence scheduling resources assignment period equals business data packet and arrives the cycle, and the time point of semi-continuous scheduling cycle appointment is the time location of service data transmission bag.To LTE FDD (Frequency Division Duplexing, Frequency Division Duplexing (FDD)) this ascending-descending subframes exists simultaneously, the system that the up-downgoing transmission is carried out simultaneously, it is all no problem how many resource allocation cycle is, but to LTE TDD (Time Division Duplexing, time division duplex) system, if resource allocation cycle is not the integral multiple in ascending-descending subframes transfer point cycle, it is the integral multiple of 5ms or 10ms, the predefine resource location that distributes by the business arrival cycle may be positioned on the subframe of different transmission directions, causes transfer of data normally not carry out.
LTE TDD is a kind of tdd systems, its frame structure as shown in Figure 1, each radio frames is made of two fields (Half-Frame), each field length is 5ms.Each field comprises that 8 length are the time slot of 0.5ms (slot); and three special time slot: DwPTS (Downlink Pilot Time Slot; descending pilot frequency time slot), GP (protection at interval) and UpPTS (Uplink Pilot Time Slot, uplink pilot time slot).The length of DwPTS and UpPTS is configurable, and the total length of DwPTS, GP and UpPTS equals 1ms.Subframe 1 and subframe 6 comprise DwPTS, GP and UpPTS, and every other subframe comprises two adjacent time slots, and wherein i subframe constitutes with 2i+1 time slot by 2i.
Support the switching point cycle of 5ms and 10ms, under 5ms switching cycle situation, UpPTS, subframe 2 and subframe 7 are reserved as uplink, under 10ms switching cycle situation, DwPTS exists in two fields, but GP and UpPTS only exist in first field, and the DwPTS length in second field is 1ms.UpPTS and subframe 2 are reserved as uplink.
According to ascending-descending subframes transfer point difference, can realize different ascending-descending subframes configurations, standard determines that the ascending-descending subframes configuration of supporting is as shown in the table at present, wherein dispose 0～2nd, 5ms ascending-descending subframes transfer point, configuration 3～6th, 10ms subframe transfer point, wherein D, U represent descending sub frame and sub-frame of uplink respectively.
Based on the characteristics of LTE tdd frame structure, if the business data packet arrival cycle is the integral multiple of 10ms, as cycle of VoIP business be 20ms, its half-persistence scheduling resources distributes as shown in Figure 2, each packet all sends on subframe X.Because 10ms is the integral multiple in switching point cycle, by suitable resource allocation, can satisfy all subframe X all is a direction, promptly all is up or all is descending.
But arriving the cycle for business data packet be the situation of 10ms integral multiple, if according to business data packet arrival period allocated predefine resource then data direction can occur and the inconsistent situation of resource direction.With 32ms cycle business is example, as shown in Figure 3, what suppose the needs scheduling is downlink business, first packet sends at descending sub frame X, then second, the 3rd, the 4th packet respectively need be in subframe (X+2) mod10, (X+4) mod10, the last transmission of (X+6) mod10, and these subframes are descending sub frame not necessarily.Be example specifically to dispose 1, if X=0 (first packet sends in subframe 0), second, the 3rd, the 4th subframe that data are responsible for assigning is respectively subframe 2,4,6, the table of comparisons 1, subframe 2 is sub-frame of uplink, impossible transmitting downlink data, subframe 6 is special subframes, whether can transmitting downlink data depend on that the length of DwPTS disposes.
Therefore, there is following shortcoming in prior art, owing to arrive the period allocated half-persistence scheduling resources by business data packet, replace the system that occurs for this ascending-descending subframes of LTE TDD, the subframe transmission direction of predefine resource location and the situation that the business datum direction is not inconsistent can occur, finally cause transfer of data normally not carry out.
