Description
Technical field
The present invention relates to moving communicating field, particularly the dedicated channel of enhancing (EnhancedDedicated Channel is called for short " E-DCH ") technology.
Background technology
Third generation partner program (3rd Generation Partnership Project, abbreviation " 3GPP ") vital tissue as moving communicating field has promoted 3G (Third Generation) Moblie (The Third Generation, be called for short " 3G ") standardization effort of technology, the carrying of uplink and downlink business all is based on dedicated channel in its early stage protocol version.
Along with the development of mobile communication technology, 3G technology is also in constantly development evolution.High speed downlink packet inserts (High Speed Downlink Packet Access is called for short " HSDPA ") and high speed uplink packet access (High Speed Uplink Packet Access is called for short " HSUPA ") is exactly the important evolution of 3G technology.The scheduling of the packet among HSDPA and the HSUPA and re-transmission etc. are controlled by base-station node (Node B).
Wherein, HSUPA is called E-DCH again, as the high speed uplink data packet access technique, has been incorporated in 2004 among the 3GPP the 6th edition (Release 6, are called for short " R6 ").E-DCH has also adopted 2 milliseconds of (ms) Transmission Time Interval (Transmission Time Interval, be called for short " TTI ") and shorter frame length to realize quick self-adapted control, use and mix automatic repeat requests (Hybrid AutoRepeat reQuest, be called for short " HARQ ") and based on the fast uplink dispatching technique of Node B, improved up spectrum efficiency, it is fast also to have uplink speed, remarkable advantages such as propagation delay time is little, thus be the real-time game business, file is uploaded, the application of grouping data services such as broadband multimedia services provides more effective support.The HARQ technological synthesis forward error correction and re-transmission, the physical layer that is used for E-DCH retransmits fast, and by first biography and the soft merging between retransmitting improve the decoding performance of physical layer.
For subscriber equipment (User Equipment, abbreviation " UE ") high-efficiency transfer of upstream data, E-DCH has increased two uplink physical channels and three down physical channels newly, they are respectively up E-DCH dedicated data transmission channel (the E-DCH Dedicated PhysicalData Channel that is used for carrying user data, be called for short " E-DPDCH "), be used to transmit accompanied by physical layer signaling, for the E-DPDCH demodulation provides the up E-DCH Dedicated Control Channel of following signaling (E-DCH Dedicated PhysicalControl Channel, be called for short " E-DPCCH "), be used to control E-DCH absolute grant channel (the E-DCH Absolute Grant Channel of the uplink speed of UE, be called for short " E-AGCH ") and E-DCH relative authorization channel (E-DCH Relative Grant Channel, be called for short " E-RGCH "), and be used to carry the E-DCH retransmission indicating chanel of confirmation (ACK/NACK) (E-DCH HARQ Indicator Channel is called for short " E-HICH ") of the whether correct affirmation of up process data transmission/not.
The media interviews control of E-DCH (Medium Access Control is called for short " MAC ") protocol layer comprises MAC-e and two media access control sublayer of MAC-es.Wherein, universal mobile telecommunications system grounding wireless access network (UMTS Terrestrial Radio Access Network, abbreviation " UTRAN ") the MAC-e entity of side is in Node B, the MAC-es entity is at service wireless network controller (Serving RadioNetwork Controller, be called for short " SRNC ") in, the MAC-e entity of UE side and MAC-es entity are in same functional unit.
MAC-e protocol Data Unit in the MAC-e entity (Protocol Data Unit, be called for short " PDU ") payload part comprise a plurality of multiplexing together MAC-es PDU, optionally be used for schedule information (the Scheduling Information of 18 bits of up fast packet scheduling, be called for short " SI "), and be used to make the length of MAC-e PDU to equal the possible filling field of the E-DCH transport block length of appointment.
Authorization of service (ServingGrant is called for short " the SG ") parameter that the up fast packet scheduling of E-DCH is based on Node B control realizes.In order to simplify the control of the up fast packet scheduling of E-DCH, a UE safeguards a SG parameter, and the upstream packet transmission of all HARQ processes of this UE is controlled by this single S G parameter all.The control of relative authorization (RelativeGrant is called for short " the RG ") order of E-RGCH is ordered and be carried on to the absolute grant (Absolute Grant, be called for short " AG ") that the SG parameter that UE safeguarded is carried on E-AGCH.
The up fast packet scheduling support of E-DCH is based on the independent scheduling mode of single UE with based on the group scheduling mode of UE group.In the independent scheduling mode based on single UE, to 2ms TTI pattern, Node B can not allow some HARQ process of UE to send schedulable transfer of data by configuration; Node B also can by AG order allow UE be in certain of non-active state or all the HARQ process send schedulable transfer of data; Node B by AG order stop certain of UE or all the HARQ process send schedulable transfer of data.
The SI transmission has very high priority, according to 3GPP protocol specification TS25.321, even current service mandate SG parameter is " Zero_Grant ", perhaps to being in the HARQ process of non-active state, perhaps to not allowing to send the HARQ process of schedulable transfer of data, all allow transmission SI, promptly all HARQ processes all allow to transmit the SI report.
SI is that E-DCH carries out the metrical information that up fast packet scheduling relied on based on Node B, except triggering based on the cycle and cause the report of UE SI reporting based on Event triggered, when the vacant bit number of MAC-e PDU is equal to or greater than 18 bits also with SI reporting.Wherein, trigger and be referred to as the SI (Triggered SI) of triggering based on the SI of Event triggered based on the cycle.
The SI transmission on E-DPDCH always, two kinds of transmission meanss are arranged: a kind of is to be transmitted separately by MAC-e PDU, and promptly whole M AC-e PDU is made of the SI of 18 bits; Another kind is that SI transmits with data, SI is placed the back of the multiplexing MAC-es PDU together of MAC-e PDU.
The method of synchronization is adopted in the processing of HARQ process among the E-DCH, i.e. the initial transmission of certain HARQ process and re-transmission always occurs in the fixing moment.To 2ms TTI pattern, always have 8 parallel HARQ processes; To 10ms TTI pattern, always have 4 parallel HARQ processes.Wherein, each HARQ process all has corresponding maximum transmission times.To the situation that SI transmits separately, maximum number of retransmissions is fixed as 8 times; The situation that SI is transmitted in MAC-e PDU with data, maximum number of retransmissions is by the HARQ configuration parameter decision of the E-DCH MAC-d stream of data division among this MAC-e PDU, this parameter is by Radio Resource control (Radio Resource Control, abbreviation " RRC ") information unit (Information Element, be called for short " IE ") " E-DCH MAC-d flow maximumnumber of retransmission (E-DCH MAC-d flows maximum retransmission) " definition, its span is 0～15.
Standard TS25.321 according to 3GPP, each UE has a corresponding HARQ entity of E-DCH, at each TTI, whether this HARQ entity is empty according to the buffering area of each HARQ process all, judgement is to produce new transmission (promptly sending new data) on corresponding HARQ process, still produces and retransmits (promptly retransmitting the legacy data in the harq buffer district).
According to the standard TS25.321 of 3GPP and the motion of approving " R2-061300; Correctionto Notification of SI transmission failure and variable resets (correction that SI transmission failure notification and variable are resetted) ", the HARQ process of UE side is handled as shown in Figure 1.
In step 101, at first, judge whether the HARQ process satisfies following three conditions simultaneously:
A1. the transmission of this HARQ process only comprises the SI of triggering, but does not comprise high level data;
A2. the current number of times that has transmitted (being preserved by variable CURRENT_TX_NB) is less than maximum transmission times;
A3. do not receive the ACK of the Radio Link collection (Radio Link Set is called for short " RLS ") that comprises Serving cell.
If a1, a2, these three conditions of a3 satisfy simultaneously, then change step 102 over to; If do not satisfy, then change step 103 over to.
In step 102, this HARQ process will be proceeded to retransmit, and change step 103 over to.
In step 103, whether one or more that further judge following three conditions satisfies:
B1. receive the ACK of the RLS that comprises Serving cell;
B2. receive the ACK of any RLS, and the transmission of this HARQ process comprises high level data;
B3. current the number of transmissions (CURRENT_TX_NB) is equal to or greater than maximum transmission times.
If satisfy at least these three conditions one of them, then change step 104 over to; Otherwise, process ends.
In step 104, empty the buffering area of this HARQ process.
In step 105, judge whether the transmission of this HARQ process is satisfied: comprise the SI of triggering, and do not receive the ACK of the RLS that comprises Serving cell.If satisfy, then change step 106 over to; Otherwise, process ends.
In step 106, the SI that this HARQ process of notice SI function of reporting fails to trigger successfully sends to the RLS that comprises Serving cell.Process ends.
If the SI that HARQ transmission triggers failure, promptly this HARQ process SI of failing to trigger successfully sends to the RLS that comprises Serving cell, and then the SI after the failure triggers flow process as shown in Figure 2.
In step 201, whether the SI that further judges the triggering of this bust this does not transmit in same MAC-e PDU with high level data is multiplexing, judges promptly whether this transmission is the SI situation of transmission separately yet, if, then further do not operate process ends; Otherwise, change step 202 over to.
In step 202, this is transmitted as the SI and the multiplexing situation about transmitting of high level data of triggering in same MAC-e PDU, therefore, triggers a new SI report.
In actual applications, there is following problem in such scheme: the transmission of SI waste Radio Resource among the E-DCH.
Cause the main cause of this situation to be, because SI transmits the influence that retransmitted by the HARQ process on E-DPDCH.As shown in Figure 3, the MAC-ePDU that comprises SI on certain HARQ process successfully do not received as yet by Node B and retransmit during, the transmission of the MAC-e PDU of new SI all may appear comprising on other HARQ process, and before this MAC-e PDU that comprises old SI successfully receives, if the MAC-e PDU that comprises new SI is transmission success, in this case, the processing in the SI triggering flow process after the handling process of HARQ process as shown in Figure 1 and the HARQ as shown in Figure 2 transmission SI failure is as follows:
Comprise the SI of triggering for MAC-e PDU but do not comprise high level data, the also SI that promptly the triggers situation of transmission separately, comprise old SI but the transmission that do not comprise the MAC-e PDU of high level data with continue retransmitting this, wait until that then the MAC-e PDU that comprises old SI successfully transmits when finishing, if Node B adopts the SI information in this Geju City to carry out the E-DCH packet scheduling, the performance of E-DCH packet scheduling certainly will will be influenced seriously.Therefore, the SI in this Geju City is useless, and Radio Resource has been wasted in the re-transmission that comprises the MAC-e PDU of old SI, has increased Node B simultaneously new and old SI is handled complexity.
The situation that comprises the SI and the high level data of triggering for MAC-e PDU simultaneously, then may trigger a new SI report by the SI function of reporting, successfully received new SI information in other HARQ process owing to comprise the RLS of Serving cell, therefore the new SI report that triggered of SI function of reporting also there is no need, and has wasted Radio Resource equally.
