Embodiment
Embodiments of the invention provide a kind of new ascending HARQ course processing method method and corresponding device, the method and device are by sorting to the HARQ process, then the process in this sequence chosen is as current process, after the time slot of the transmission time slot that calculates current process and current time slots is poor, utilize the relation of the poor and default time slot of this time slot between poor, adjust gradually the current process of choosing, until choose the HARQ process to be processed that needs, avoided whole processes of base station are carried out traversal search, save the access time of process, thereby improved operating efficiency.
For ease of understanding technical scheme of the present invention and technical characterictic, below in conjunction with drawings and Examples the present invention is described in detail.
In the prior art, in the time of need to dispatching the HARQ process, at first to from all processes of base station, choose the HARQ process to be processed that needs, the mode of choosing is to compare one by one, judge that the poor default time slot that whether equals this process of the transmission time slot of each process and the time slot between the current time slots is poor, because the UE number of devices of base station is large, the process number of each UE equipment is more, has traveled through all HARQ processes and will spend the plenty of time.For this reason, the invention provides a kind of fast selecting method to the HARQ process.Accompanying drawing 1 shows one embodiment of the present of invention.A kind of ascending HARQ course processing method that this embodiment provides comprises:
Step S101: arrange the HARQ process according to transmission time slot;
The timeslice that takies when transmission time slot is transfer of data, different data are in when transmitting on the points different on the time shaft, a HARQ process is all opened to each data transmission procedure in the base station, because the transmission time slot of each process is different, therefore can these HARQ processes be sorted time order and function, the mode of ordering can according to the time by early arranging to evening, also can be arranged to morning by evening, HARQ process after the ordering forms a sequence list, if sortord is " by early to evening " mode, the transmission time slot of the HARQ process before the process of then therefrom choosing is all early than this process, and the transmission time slot of the HARQ process after this process all is later than this process; In like manner, " by evening to early " arrangement mode has similar effect; The order chained list that the ordering of HARQ process forms can adopt the FIFO mode to store, and also can adopt list structure to store.It should be noted that if there is concurrent process in the HARQ process then these concurrent processes can " bundling " formula sort as a whole.
Step S102: when carrying out the HARQ process scheduling, choose a HARQ process as current process;
After the HARQ process sorted, in the time of need to carrying out that by the time the HARQ process carried out uplink scheduling, from the HARQ process of this arrangement, select a HARQ process, and it is designated current process; Here select the HARQ process can select arbitrarily one, also can choose from head or the afterbody of the HARQ process of arranging, this depends on the concrete storage mode of the HARQ process of arrangement, store such as adopting list structure body mode, then can select first HARQ process, then seek backward according to the following steps suitable HARQ process and deal with the work.
Step S103: calculate the transmission time slot of described current process and the time slot difference between current time slots, this time slot difference is poor for calculating time slot;
Time slot when carrying out the HARQ process scheduling and processing is current time slots, and this current time slot is in after the HARQ process of base station, and this current time slot is deducted the transmission time slot of the current process that abovementioned steps chooses, and obtains the time slot difference.
Step S104: more described calculating time slot default time slot poor and described current process is poor, if it is poor poor greater than default time slot to calculate time slot, and execution in step S104 (a) then; If it is poor poor less than default time slot to calculate time slot, then execution in step S104 (b); Poor to equal default time slot poor if calculate time slot, then execution in step S104 (c);
The front makes referrals to for synchronous HARQ mechanism, the transmission of a HARQ process has fixed timing relationship with re-transmission, this sequential relationship embodies by time slot is poor, the default time slot that is herein is poor, this is preset, and time slot is poor to be disposed according to uplink and downlink timeslot by the base station when the initialization of base station, and the default time slot that can obtain corresponding HARQ process by the configuration result that reads the base station is poor; Obtain the default time slot of current HAQR process poor after, with poor the comparing of calculating time slot that itself and abovementioned steps calculate, then adjust adaptively current process according to comparative result.
Step S104 (a): again choose a HARQ process that is later than described current process according to preset rules, return step S103;
If it is poor poor greater than default time slot to calculate time slot, the current process of description selection is not to need HARQ process to be processed, therefore need to adjust this process, the detailed process of adjusting is relevant with the arrangement mode of HARQ process, if the HARQ process is according to the ascending arrangement of transmission time slot, then again choose a HARQ process after current process according to preset rules, the transmission time slot of the HARQ process under this situation after the current process and poor must the reducing of time slot of current time slots; If the HARQ process is according to the descending arrangement of transmission time slot, then again choose a HARQ process before current process according to preset rules, the transmission time slot of the HARQ process under this situation before the current process and poor must the reducing of time slot of current time slots, select more draw close real need HARQ process to be processed after, further adjust according to abovementioned steps again; The preset rules here comprises by current HARQ process choosing of 1 HARQ process compartment forward or backward, also can be that a plurality of HARQ compartment processes are chosen, and the interval of choosing is larger, and the speed of convergence will be accelerated.
Step S104 (b): again choose one early than the HARQ process of described current process according to preset rules, return step S103;
If it is poor poor less than default time slot to calculate time slot, the current process of description selection is non-need HARQ process to be processed also, therefore need to adjust this process, the concrete mode and the above-mentioned S104 (a) that adjust are similar: if the HARQ process according to the ascending arrangement of transmission time slot, then described HARQ process early than current process is positioned at before the current process; If the HARQ process is according to the descending arrangement of transmission time slot, described HARQ process early than current process is positioned at after the current process, that selects in the manner described above is positioned at before the current process/transmission time slot of afterwards HARQ process and poor must the reducing of time slot of current time slots, thus accelerating ated test.
Step S104 (c): current process is processed process ends.
If the poor default time slot with current process with the time slot between the current timing crack of the transmission time slot of current process is during poor equating, the ascending time slot that current scheduling is described is this HARQ process re-transmission time slot, at this moment can process current process, the mode of processing has multiple, present embodiment is processed according to following mode: judge whether to receive data, if so, then from the HARQ alignment procedure, remove current process; If not, then read the number of retransmissions of HARQ process, if described number of retransmissions does not reach default maximum retransmission, then carry out data re-transmission and process.
The embodiment of the invention is arranged according to the transmission time slot process the HARQ process of base station, when carrying out the HARQ process scheduling, from the HARQ process of arranging, choose a HARQ process, then the transmission time slot and the time slot between current time slots that calculate the process of choosing are poor, and with poor the comparing of the poor and default time slot of this time slot, selecting needs HARQ process to be processed, thereby this HARQ process is processed.Compared with prior art, the embodiment of the invention adopts " drawing close gradually method ", and gradually approaching needs HARQ process to be processed, and does not need whole HARQ processes of base station are carried out traversal search, save the time of choosing the HARQ process, improved HARQ process treatment effeciency.
In order more to be expressly understood present embodiment, the below describes with a concrete example.In this example list structure bodily form formula is adopted in the arrangement of HARQ process, choose first HARQ process of this chained list as initial current process from this list structure body, aforesaid preset rules is to adjust backward according to a HARQ process interval.The structure of the doubly linked list that this example adopts as shown in Figure 2, this list structure body is comprised of the node HarqNode corresponding with the HARQ process, the information of each HarqNode node comprises the pointer (previous) that points to a upper node and the pointer (next) that points to next node, and whole chained list (HarqList) structure comprises the pointer (head) that points to this chained list gauge outfit node and the pointer (tail) that points to the afterbody node.Initialization when this list structure body is set up in the residential quarter, when system carries out uplink scheduling when sending up new data, obtain corresponding HARQ process, and add this process to the chained list afterbody as a node HarqNode, then upgrade structure, with arranged sequentially according to transmission time slot of the HARQ process node that guarantees to store in the chained list; When carrying out uplink scheduling need to process ascending HARQ course the time, the corresponding process of gauge outfit information searching by storage in the doubly linked list then; When deletion UE, delete first HARQ process corresponding to UE, then from chained list, remove this HARQ process, to keep the continuity of chained list.
Referring to accompanying drawing 3, the ascending HARQ course processing method that above-mentioned example provides comprises:
Step S300: the first node pnode that obtains doubly linked list;
Step S301: judge whether first node pnode is empty, if should head node pnode be empty, illustrate that the time slot of current uplink scheduling does not have HARQ process to be processed, process ends; If should head node pnode not be sky, then execution in step S302.
Step S302: obtain HARQ process corresponding to this node as current process, pnode is pointed to the next node of doubly linked list; And calculate the poor differ of time slot between the ascending time slot of the transmission time slot of this current process and current scheduling.

Step S304: differ and delay are compared, the time slot loss situation occurs if differ, illustrates current system greater than deley, the one or many ascending time slot namely occurs and do not dispatch, then execution in step S305; Do not have to process the time slot of current process if differ, illustrates current scheduling less than delay, and the whole HARQ processes after this current process are all ineligible, then pnode pointed to back node corresponding to current process, process ends; If differ equals delay, illustrate that current process is the current scheduling ascending time slot and needs HARQ process to be processed, then execution in step S306.
Step S305: current process is carried out the unusual processing of time slot, abnormality processing comprises the transmission time slot that upgrades current process, it is moved to the afterbody of doubly linked list, process execution in step S301 after abnormality processing is finished when waiting for that next time time slot scheduling arrives.
Step S306: read the physical layer feedback of current process, to judge whether to receive data, if be fed back to ACK, illustrate correctly to receive the data that transmitting terminal sends, i.e. current process transmission success, then execution in step S311; If be fed back to NACK, illustrate correctly not receive the data that transmitting terminal sends, i.e. current process bust this, then execution in step S307.
Step S307: read the number of retransmissions of current process, compare number of retransmissions and default maximum retransmission, if number of retransmissions does not reach maximum retransmission, execution in step S308; If number of retransmissions has reached maximum retransmission, execution in step S309 then.
Step S308: current process is carried out retransmission process, then execution in step S310.
Step S309: current process is reached the processing of maximum retransmission, then execution in step S311.
Step S310: current process is moved on to the doubly linked list tail end, and upgrade doubly linked list, then execution in step S301.
