Description
Technical field
The present invention relates to the communications field, relate in particular to a kind of data processing method, device and system.
Background technology
At present, Long Term Evolution (Long Term Evolution, LTE) in the system, reliability for the transmission of raising system, adopt the automatic repeat requests of mixing (the Hybrid AutomaticRetransmission Request of stop-and-wait, HARQ) mechanism, and adopt a plurality of HARQ processes (Process) parallel processing data, on down direction, adopt asynchronous HARQ, its retransmission time is uncertain, therefore, and evolution base station (evolved NodeB, eNB) when carrying out the data transmission, need indicate the HARQ process process number (Process ID, PID), the pid information of HARQ is included in downstream grants (DownlinkGrant) signaling, and Physical Downlink Control Channel (Physical Downlink Control Channel, PDCCH) the middle transmission.
In LTE, need to support Voice over IP (Voice over IP, real time business such as VoIP), the VoIP business has conversation and quiet two states, usually VoIP every 20ms during conversing produces a speech frame, because VoIP is relatively more responsive to time delay and shake, in order to satisfy the service feature of VoIP, when the VoIP business is in talking state, usually every VoIP voice packet of 20ms scheduling.When eNB just enters talking state at VoIP, by the indication of the downstream grants signaling on PDCCH subscriber equipment (User Equipment, UE) receive the descending VoIP data, and indication all is that UE keeps identical therewith downlink resource every 20ms backward, be used to send new VoIP data, this scheduling mode is called static scheduling, and the moment that keeps downlink resource is called static scheduling constantly, and the scheduling that sends new data at static scheduling constantly is called the initial static scheduling.In order to reduce the downstream grants signaling consumption on the PDCCH, send when just having entered talking state the downstream grants signaling except VoIP, do not send the downstream grants signaling constantly usually at other static schedulings.If the data decode that UE receives when initial static is dispatched failure then needs to retransmit, the dynamic dispatching pattern is adopted in the re-transmission to static scheduling among the LTE.When carrying out dynamic dispatching, eNB need send downstream grants signaling indication PID, indicates PID by the downstream grants signaling when promptly eNB retransmits static scheduling.
In order to support descending semi-persistent scheduling mode, promptly comprise the transmission means of static scheduling and dynamic dispatching, system need reserve the HARQ process for descending semi-persistent scheduling.Because eNB transmits corresponding HARQ process without downstream grants signaling indicating downlink constantly usually at static scheduling, the asynchronous HARQ mode of descending employing simultaneously, cause downlink transfer and HARQ process not to have corresponding relation, therefore must define mapping relations, to not have the downlink transfer of PID indication to be mapped to a HARQ process constantly at static scheduling, both receiving-transmitting sides be mapped to the HARQ process with identical PID with same initial static scheduling; Otherwise, when UE receives new data constantly at static scheduling, will not know which HARQ process this gives and handle, and causes the HARQ operation exception.
At above problem, existing method is by system configuration/reconfiguration system frame number (SystemFrame Number, SFN) and be mapping relations between the HARQ process that semi-persistent scheduling reserves, eNB and UE calculate the PID of each down initial static scheduling by SFN.It is the semi-persistent scheduling of system-frame time (10ms) integral multiple that but this method only is applicable to the pre-allocation resource cycle.ENB need use special this mapping relations of signaling configuration/reconfiguration, has increased complexity and expense.In addition, this mapping method lacks flexibility, when channel quality becomes very poor suddenly, can cause loss of data owing to the operation of the HARQ process of forcing end using, and has reduced the efficient of transfer of data.
