Description
Technical field
The present invention relates to the communications field, send processing method and device in particular to a kind of detection method, Radio Link control data.
Background technology
Radio Link control (the Radio Link Control of 3-G (Generation Three mobile communication system); Abbreviating RLC as) affirmation mode guarantees (for example to be sent to high-rise data at receiving terminal through " sending in order "; Protocol Data Unit (Protocol Data Unit; Abbreviate PDU as)) order is consistent with order under transmitting from high level at transmitting terminal, comprises the sequence number that the sequence number territory provides 12 bits (bit) in the RLC data PDU of affirmation mode,, data are provided with in order when sending; Require to retransmit wrong PDU through " error code correction ", transmitting terminal requires receiving terminal to send an affirmation and replys report, to confirm that the PDU which receives is wrong.
The affirmation mode Radio Link control automatic repeat requests of (abbreviating AM RLC as) entity (abbreviating ARQ as) receiving terminal responsive state is reported in the peer-entities transmission of recipient and transmit leg; Status report can carry through status PDU (STATUS PDU) or subsidiary status PDU (piggybacked STATUS PDU); Wherein comprise acknowledge message (abbreviating ACK as) or non-acknowledge message (abbreviating NACK as), data packet format has bitmap (BITMAP), tabulation (LIST), relative tabulation (RLIST) three kinds.The trigger mechanism of status report is: periodically, protocol data unit of wireless links control layer (RLC PDU) loss detection, receive transmitting terminal in turn detect-message (Polling), under variable RLC SIZE pattern, receive four kinds of triggering modes of superwood section poll (POLL SUFI) of transmitting terminal.
In order to reach the especially throughput of cell edge of higher data throughout; Technical Analysis and demonstration through 3GPP; A kind of enhancement function is proposed: subscriber equipment (User Equipment; Abbreviate UE as) can be simultaneously from different base stations (for example, NodeB) or two sub-districts of the identical frequency of identical NodeB or same frequency receive data block simultaneously, promptly in same Transmission Time Interval (abbreviating TTI as); UE can receive the data block that is equivalent to two times of traditional modes, is called DF-DC-HSDPA or SF-DC-HSDPA technology.The pattern that receives the different districts data block at same NodeB is called the Intra-NodeB pattern; The pattern that receives the different districts data block at different N odeB is called the Inter-NodeB pattern.Under the Intra-NodeB pattern; Be that UE receives data by same all transfer of data of NodeB control from two sub-districts of a NodeB simultaneously; Therefore, NodeB and UE only need to have a MAC-ehs entity, and each data flow all has independently HARQ entity handles; But under the Inter-NodeB pattern, promptly UE receives data from two sub-districts of two NodeB simultaneously, and U E must possess the reciprocity MAC-ehs entity that two evolution high speed downlink packet insert two different N odeB of medium access controls (MAC-ehs) entity handles.Therefore; Recipient UE will inevitably receive discontinuous RLC PDU; And, must satisfy the trigger condition that protocol data unit of wireless links control layer is lost monitoring, therefore according to the principle and the status report trigger mechanism of present 3GPP agreement " sending in order "; Recipient UE must report the SN gap that receives through status report, i.e. the non-acknowledge message ACK of SN; Transmit leg RNC retransmits according to unacknowledged PDU sequence number in the status report.For example, sequence number (Sequence Number abbreviates SN as) is that 1,2,3 RLC PDU sends at cell1; SN is that 4,5,6 RLC PDU sends at cell2, under the normal condition, at first TTI; Recipient UE can receive SN be 1 with SN be 4 PDU, according to present protocol processes, UE need trigger status report and report; SN is that 2,3 PDU is unacknowledged, and RNC receives that will retransmit SN behind such status report is 2,3 PDU.And in fact; Do not receive that SN is that 2,3 PDU is not because the error of transmission or lose of eating dishes without rice or wine; But since transmit leg through two different sub-districts respectively the recipient that causes of sending order data must receive discontinuous PDU, promptly be that the SN that do not need RNC to retransmit " losing " is 2,3 PDU in this case.
