Detailed description of the invention
Fig. 1 is the communication system architecture figure of prior art. As shown in Figure 1, conventional communication system comprisesTerminal and with the network side of terminal communication. Wherein, network side for example comprises base station and core net etc., terminalBe for example personal digital assistant (PDA) or mobile phone etc. Terminal further comprises physical layer and media accessControl (MAC) layer, wherein in physical layer, be provided with the Wireless Telecom Equipments such as antenna, for realizing terminalAnd the transfer of data between network side; The scheduling that MAC layer is responsible for upstream data sends.
Network side is many up logic channels for business data transmission of terminal configuration. When up logicWhile being cached with data to be sent on channel, the physical layer of terminal sends data transfer request to network side,And obtain the uplink authorization resource that network side is terminal distribution. Physical layer is obtaining after uplink authorization resource,Notice media Access Controls (MAC) layer multiple up logic channels are dispatched, with according to obtainedUplink authorization resource, utilize up logic channel to carry out transmitting uplink data.
Embodiment mono-
The uplink data transmission method of the embodiment of the present invention one is carried out by the terminal in Fig. 1. Below from endThe angle of end is elaborated to the uplink data transmission method of the embodiment of the present invention one.
Fig. 2 is the flow chart of the uplink data transmission method of the embodiment of the present invention. As shown in Figure 2, on thisRow data transmission method comprises the following steps:
Step S201, the physical layer of terminal is obtained the uplink authorization signaling of the scrambling that network side issues;
Step S202, described physical layer judges institute according to the scrambling mode of the uplink authorization signaling of described scramblingState the authorization type of uplink authorization signaling;
Step S203, described physical layer is notified described authorization type on the MAC layer of described terminal;
Step S204, the described MAC layer basis entry-into-force time computation rule corresponding with described authorization type,Obtain the mandate entry-into-force time of the uplink authorization signaling of described scrambling;
Step S205, described MAC layer is according to the described mandate entry-into-force time, to described authorization type pairThe business datum of answering is carried out uplink.
Particularly, when terminal has the business datum that needs up transmission, send to network side by physical layerData transfer request, this data transfer request carries terminal iidentification and traffic data type mark. NetworkSide joint is received after this data transfer request, for terminal distribution uplink authorization resource is (for carrying out upper line numberReportedly defeated time interval resource), determine authorization type according to traffic data type mark, and generate uplink authorizationSignaling, this uplink authorization signaling carries uplink authorization resource and the modulation coding mode that promising terminal is distributedDeng.
Wherein, whether network side, in the time being terminal distribution uplink authorization resource, detects available free resource, ifHave, utilize idling-resource for terminal distribution uplink authorization resource; If there is no idling-resource, network sideThe priority that query traffic data type identification is corresponding, and carry out resource according to this priority and seize, if robAccounting for successfully, is terminal distribution uplink authorization resource according to the resource of seizing; If seize failure, to endEnd returns to the information that request is failed; Preferably, network side is that the business setting of delay sensitive class is higherPriority, for example, arranges the priority > data service of the priority > signaling traffic of group's speech businessPriority. In addition,, for group's speech business, also can divide into and activate the speech business of group and notActivate the speech business of group, and the priority > un-activation group of the speech business that activated group is setThe priority of speech business, with ensure to start the group of call have resource can with and time delay minimum; RightIn the speech business of un-activation group, because its priority is still higher than priority and the data industry of signaling trafficThe priority of business, still can guarantee needs the group that sets up call to set up as early as possible, starts to lead to thereby reduce groupThe time delay of words.
For uplink authorization signaling being offered to the terminal corresponding with terminal iidentification, network side is according to authorization typeSelecting scrambling mode, uplink authorization signaling is carried out to scrambling, is to send to identify this uplink authorization signalingWhich terminal. More specifically, in LTE system, each terminal configuration has exclusive wireless network to faceTime mark (RNTI), network side carries out scrambling by the RNTI by terminal to uplink authorization signaling and distinguishesTerminal, for the uplink authorization signaling of the different authorization types of same terminal, can be by dissimilarRNTI carry out scrambling. For example, LTE system comprises semi-persistent scheduling mandate and dynamic dispatching mandate,For semi-persistent scheduling mandate, network side adopts the semi-persistent scheduling Cell Radio Network Temporary Identifier/Identity, Cell-RNTI of terminal(SPSC-RNTI) uplink authorization signaling is carried out to scrambling; For dynamic dispatching mandate, network side adoptsThe Cell Radio Network Temporary Identifier/Identity, Cell-RNTI (C-RNTI) of terminal carries out scrambling to uplink authorization signaling. Wherein,SPSC-RNTI and C-RNTI are by the pre-configured terminal of giving of network side.
The physical layer of terminal sends after data transfer request, and Physical Downlink Control Channel (PDCCH) is enteredRow is monitored, by by the SPS of the SPSC-RNTI of self and/or C-RNTI and uplink authorization signaling scramblingC-RNTI or C-RNTI compare, and obtain network side and be handed down to the uplink authorization signaling of oneself. WhenTerminal gets after the uplink authorization signaling that network side is handed down to oneself, according to the scrambling of uplink authorization signalingMode, i.e. SPSC-RNTI scrambling or C-RNTI scrambling, determine authorization type, if SPSC-RNTIScrambling, knows that network side has carried out semi-persistent scheduling mandate to terminal, if C-RNTI scrambling,Know that network side has carried out dynamic dispatching mandate to terminal.
Authorization type is notified MAC layer by physical layer, so that MAC layer is selected according to authorization type is correspondingEntry-into-force time computation rule, and calculate uplink authorization resource according to selected entry-into-force time computation ruleEntry-into-force time. For simplicity, hereinafter, the uplink authorization resource of semi-persistent scheduling authorization type is claimedFor semi-static scheduling resources, the uplink authorization resource of dynamic dispatching authorization type is called to dynamic dispatching resource.Wherein, in MAC layer, preset respectively the different entry-into-force time computation rules corresponding from different authorization types,For example, semi-persistent scheduling mandate is corresponding to the first entry-into-force time computation rule, according to the first entry-into-force time meterCalculate the regular entry-into-force time that can calculate semi-static scheduling resources; Dynamic dispatching mandate comes into force corresponding to secondTime rule, can calculate entry-into-force time of dynamic dispatching resource according to the second entry-into-force time computation rule.
MAC layer obtained after the entry-into-force time of uplink authorization resource, can be by by current time and up awardingThe entry-into-force time of power resource compares, know current come into force for semi-static scheduling resources or dynamic dispatchingResource, if what come into force current is semi-static scheduling resources, carries out the transmission of semi-static scheduling data, ifCurrent come into force for dynamic dispatching resource, carry out the transmission of dynamic dispatching data. Wherein, in MAC layerPreset traffic data type list, in this traffic data type list, store each business number in this terminalAccording to traffic data type mark (for example, speech data mark, text data mark etc.), and this industryBusiness data are the mark of semi-static scheduling data or dynamic dispatching data.
According to the uplink data transmission method of above-described embodiment, by by terminal according to uplink authorization signalingScrambling mode is resolved, the authorization type of identification uplink authorization signaling, and upper to different authorization typesThe entry-into-force time of row authorization signaling is distinguished, and is sent out according to the entry-into-force time of uplink authorization signaling by terminalSend corresponding service data, make terminal to carry out sending out of business datum according to the mandate scheduling of network side completelySend. In the case, if network side carries out semi-persistent scheduling mandate for the delay sensitive class business of terminal,Carry out dynamic dispatching mandate for non-delay sensitive class business, because end side authorizes semi-persistent schedulingThe entry-into-force time of dynamic dispatching mandate is distinguished, and in up biography of the entry-into-force time of semi-persistent scheduling mandateThe defeated business datum corresponding with semi-persistent scheduling type, so can be because of corresponding to non-delay sensitive class businessThe priority of counterlogic channel is higher than the priority of delay sensitive class business counterlogic channel, and producesNon-delay sensitive class business is seized the situation of the uplink authorization resource of delay sensitive class business, has fully ensuredThe fast transport of delay sensitive class business.
Further, in the uplink data transmission method of above-described embodiment, described MAC layer according toThe entry-into-force time computation rule that described authorization type is corresponding, the mandate of obtaining described uplink authorization signaling comes into forceTime specifically comprises:
If described authorization type is semi-persistent scheduling mandate, according to preset reception uplink authorization signalingIntrons frame number between the subframe that subframe and upstream data send and semi-static scheduling cycle calculate instituteState and authorize the entry-into-force time;
If described authorization type is dynamic dispatching mandate, according to the son of preset reception uplink authorization signalingIntrons frame number between the subframe that frame and upstream data send, calculates the described mandate entry-into-force time.
Particularly, if MAC know and receive the semi-persistent scheduling that network side issues according to the notice of physical layerAuthorize, calculate in such a way the frame number SFN that comes into force of semi-static scheduling resourcescurrentWith the subframe numbers that comes into forceSubframestarttime：
Subframestartime＝Subframereceive_PDCCH+n
If Subframestartime/ FrameLength > 1:
SFNstarttime＝SFNreceive_PDCCH+1，Subframestarttime＝SubframestartimemodFrameLength；
If Subframestartime/ FrameLength≤1: SFNstarttime＝SFNreceive_PDCCH；
SFNcurrentShould meet the following conditions:
If SFNcurrent＞SFNstarttime, should meet:
(SFNcurrent-SFNstarttime)mod(semiPersistSchedIntervalUL/FrameLength)＝0
If SFNcurrent≤SFNstarttime, should meet:
(1023+SFNcurrent-SFNstarttime)mod(semiPersistSchedIntervalUL/FrameLength)＝0
Wherein n is between the subframe of preset reception uplink authorization signaling and subframe that upstream data sendsIntrons frame number, the concrete setting value of n is deferred in 3G (Third Generation) Moblie technology (3GPP), receivesTiming relationship between the subframe that the subframe of uplink authorization signaling and upstream data send; FrameLength isFrame length, semiPersistSchedIntervalUL is semi-static scheduling cycle, by network side in advance by eating dishes without rice or wineMessage arrangement is to terminal; SFNreceive_PDCCHFor the physical layer of terminal is received the frame number of uplink authorization signaling;SubframestarttimeFor the physical layer of terminal is received the subframe numbers of the subframe of uplink authorization signaling.
By the way, can calculate the frame number SFN that comes into force of semi-static scheduling resourcescurrentWith the son that comes into forceFrame number Subframestarttime, by the subframe numbers of the frame number of present frame and current subframe and semi-persistent scheduling are providedThe frame number SFN that comes into force in sourcecurrentWith the subframe numbers Subframe that comes into forcestarttimeCompare respectively, when these two ginsengsNumber homogeneous phase simultaneously, knows that current time semi-static scheduling resources comes into force, if there is not phase of any one parameterWith or two parameters all not identical, be informed in current time semi-static scheduling resources Pending The Entry Into Force. In addition,Also can be according to the frame number SFN that comes into force of semi-static scheduling resourcescurrentWith the subframe numbers Subframe that comes into forcestarttime, willThe entry-into-force time of semi-static scheduling resources is expressed as FrameLength*SFNcurrent+Subframestarttime。
If MAC is known and is received the dynamic dispatching mandate that network side issues according to the notice of physical layer, pressesCalculate the frame number SFN that comes into force of dynamic dispatching resource according to following modestarttimeWith the subframe numbers that comes into forceSubframestarttime：
Subframestartime＝Subframereceive_PDCCH+n
If Subframestartime/ FrameLength > 1:
SFNstarttime＝SFNreceive_PDCCH+1，Subframestarttime＝SubframestartimemodFrameLength；
If Subframestartime/ FrameLength≤1: SFNstarttime＝SFNreceive_PDCCH；
Wherein n is between the subframe of preset reception uplink authorization signaling and subframe that upstream data sendsIntrons frame number, the concrete setting value of n is deferred in 3G (Third Generation) Moblie technology (3GPP), receivesTiming relationship between the subframe that the subframe of uplink authorization signaling and upstream data send; FrameLength isFrame length; SFNreceive_PDCCHFor the physical layer of terminal is received the frame number of uplink authorization signaling; SubframestarttimeFor the physical layer of terminal is received the subframe numbers of the subframe of uplink authorization signaling. In addition, also can be according to dynamic tuneThe frame number SFN that comes into force of degree resourcestarttimeWith the subframe numbers Subframe that comes into forcestarttime, by the life of dynamic dispatching resourceEffect time representation is 10*SFNstarttime+Subframestarttime。
Further, in the uplink data transmission method of above-described embodiment, described physical layer will described in awardThe MAC layer that power type is sent to described terminal specifically comprises:
Described physical layer sends interlayer message to described MAC layer, and described interlayer message carries for tableShow the identification information of described authorization type.
Particularly, in this interlayer message, utilize a bit to identify authorization type, for example, show with " 0 "Show semi-persistent scheduling, represent dynamic dispatching with " 1 ". MAC layer by the numerical value of this bit of identification isCan know that authorization type is semi-persistent scheduling or dynamic dispatching.
In addition the physical layer that, this interlayer message also can be used for carrying above-mentioned terminal is received uplink authorization signalingFrame number SFNreceive_PDCCH, and the physical layer of terminal is received the subframe numbers of the subframe of uplink authorization signaling Subframestarttime, so that MAC layer carries out the calculating of entry-into-force time according to these two parameters.
Further, in the uplink data transmission method of above-described embodiment, in uplink authorization signaling, also canCarry and authorize bit number (TotalSendBitNum), correspondingly, physical layer is carried at above-mentioned by this parameterIn interlayer message, be sent to MAC layer.
Network side for example arranges mandate bit number in the following manner:
Authorize bit number=layer two packet header+business data packet size+buffer memory to report the bit number taking.
Wherein, business data packet depends on the transfer rate by business datum, and this transfer rate is deferred to current logicalThe communication protocol that communication system adopts; Buffer memory report is for being reported the number of current terminal to network side by terminalAccording to caching situation, so that network side can be that terminal issues mandate according to the data buffer storage situation of terminal.
Respectively for semi-persistent scheduling mandate and two kinds of situations of dynamic dispatching mandate, MAC layer is held belowThe process of row uplink data scheduling and transmission is elaborated.
MAC layer is by the frame number that comes into force of the frame number of current time and subframe numbers and semi-static scheduling resourcesSFNcurrentWith the subframe numbers Subframe that comes into forcestarttime, and/or the frame number SFN that comes into force of dynamic dispatching resourcestarttimeWithSubframe numbers Subframe comes into forcestarttimeCompare, have following several situations:
Situation one: the frame number of current time and subframe numbers only with the frame number that comes into force of semi-static scheduling resourcesSFNcurrentWith the subframe numbers Subframe that comes into forcestarttimeConform to, determine that the authorization type that current time comes into force is halfStatic scheduling mandate, carry out following steps:
Step 101, MAC layer is chosen logic channel from the logic channel group corresponding with static scheduling mandate;
Particularly, network side has logic channel group for terminal configuration in advance, and each logic channel group comprises oneIndividual or multiple logic channels. Preferably, network side is type of service corresponding to semi-persistent scheduling mandate and movingThe type of service that state scheduling authorization is corresponding configures different logic channel groups, to configure two logic channel groupsFor example, one of them logic channel group is for the upstream data of type of service corresponding to semi-persistent scheduling mandateSend (hereinafter this logic channel group being called to " semi-persistent scheduling logic channel group ") another logicChannel group sends (hereinafter by this logic for the upstream data of type of service corresponding to dynamic dispatching mandateChannel group is called " dynamic dispatching logic channel group "). When network side is that configuration semi-persistent scheduling is divided in termination environmentWhen logic channel group and dynamic dispatching logic channel group, because the buffer memory of terminal to report is reported conventionally with logicChannel group is unit, can make network side know and know that semi-persistent scheduling mandate is to just seeing the slow of business datumDeposit situation.
For example: in LTE system, only authorization type corresponding to group's speech business is set to semi-static tuneDegree is authorized, and such as, by equal authorization type corresponding other business (multimedia service, downloading service etc.)Be set to dynamic dispatching mandate, in semi-persistent scheduling logic channel group, only comprise a logic channel, shouldLogic channel sends for the upstream data of group's speech business, and comprises in dynamic dispatching logic channel groupMultiple logic channels, the plurality of logic channel is respectively used to other business except group's speech businessUpstream data sends. In the time that logic channel group comprises many logic channels, network side is also each logic channelPriority is set, so that terminal is while dispatching the logic channel in this logic channel group, according to logicThe priority of channel is dispatched.
Step 102, determines the data volume that reality can send;
Particularly, for example, to have chosen logical channel number as group service channel (GTCH) in step 102Logic channel (hereafter GTCH channel), GTCH channel is for realizing group's speech businessUpstream data sends, with BitNumCTCHRepresent the data volume that GTCH channel once can transmit, below pressingMode is determined the data volume that reality can send:
PlayLoad＝TotalSendBitNum-L2HeadBit
If BitNumGTCH> PlayLoad, the actual data volume sending is PlayLoad;
If BitNumGTCH≤ PlayLoad, the actual data volume sending is BitNumGTCH；
Wherein, TotalSendBitNum is the mandate bit number carrying in uplink authorization signaling; L2HeadBit isL2 packet header size, its occurrence is deferred to 3GPP agreement.
Because the size of data of group's speech business is more fixing, therefore network side in the time carrying out scheduling authorization,For the mandate bit number of terminal distribution is greater than group's speech business size of data that terminal need send conventionally, withMake terminal can in a upstream data sends, complete whole groups speech business data of institute's buffer memory; If reallyThe data volume that fixed reality can send is less than group's speech business size of data that terminal need send, residueData send at next semi-static scheduling cycle.
The data volume that step 103, MAC layer can send according to determined reality, from selected logicThe extracting data data of channel buffer memory, composition MAC wrap and be sent to physical layer, and by physical layer toNetwork side sends.
Situation two: the frame number of current time and subframe numbers only with the frame number SFN that comes into force of dynamic dispatching resourcecurrentWith the subframe numbers Subframe that comes into forcestarttimeConform to, determine that the authorization type that current time comes into force is that dynamic dispatching is awardedPower, carry out following steps:
Step 201, MAC layer is chosen logic channel from the logic channel group corresponding with dynamic dispatching mandate;
Particularly, in the time that the logic channel group corresponding with moving scheduling authorization comprises many logic channels,MAC layer selects according to the priority of each logic channel or according to the ascending order of logical channel numberSelect;
Step 202, determines the data volume that reality can send;
Concrete definite method is identical with situation one;
Step 203, the data volume that MAC layer can send according to determined reality, from selected logicThe extracting data data of channel buffer memory, composition MAC wrap and be sent to physical layer, and by physical layer toNetwork side sends.
The frame number SFN that comes into force of the frame number of situation three, current time and subframe numbers and semi-static scheduling resourcescurrentWith the subframe numbers Subframe that comes into forcestarttime, and the frame number SFN that comes into force of dynamic dispatching resourcecurrentWith the son that comes into forceFrame number SubframestarttimeAll do not conform to, determine the scheduling authorization that current time does not come into force, do not carry out upTransfer of data.
The frame number SFN that comes into force of the frame number of situation four, current time and subframe numbers and semi-static scheduling resourcescurrentWith the subframe numbers Subframe that comes into forcestarttime, and the frame number SFN that comes into force of dynamic dispatching resourcecurrentWith the son that comes into forceFrame number SubframestarttimeAll meet, MAC checks the buffer memory of all logic channels, if only GTCH patrolsIt is not empty collecting channel buffer memory, uses semi-static scheduling resources; If go back except GTCH logic channelThere are other logic channel buffer memories not for empty, use dynamic dispatching resource, and preferentially by GTCH logicThe data of channel are put into the packet sending.

The 4th processing module 321, for the basis entry-into-force time computation rule corresponding with described authorization type,Obtain the mandate entry-into-force time of the uplink authorization signaling of described scrambling;
The 5th processing module 322, for according to the described mandate entry-into-force time, to described authorization type pairThe business datum of answering is carried out uplink.
The terminal of above-described embodiment is carried out the upper of the idiographic flow of transmitting uplink data and previous embodimentRow data transmission method is identical, so locate to repeat no more.
According to the terminal of above-described embodiment, resolve by the scrambling mode according to uplink authorization signaling,The authorization type of identification uplink authorization signaling, and when the coming into force of uplink authorization signaling to different authorization typesBetween distinguish, and send corresponding service data by terminal according to entry-into-force time of uplink authorization signaling, makeObtain terminal and can carry out the transmission of business datum according to the mandate scheduling of network side completely. In the case, ifNetwork side carries out semi-persistent scheduling mandate for the delay sensitive class business of terminal, for non-delay sensitive classBusiness is carried out dynamic dispatching mandate, because end side authorizes the life of dynamic dispatching mandate to semi-persistent schedulingThe effect time is distinguished, and in the uplink of the entry-into-force time of semi-persistent scheduling mandate and semi-persistent scheduling classThe business datum that type is corresponding, thus can be because of corresponding to non-delay sensitive class business counterlogic channel excellentThe first grade priority higher than delay sensitive class business counterlogic channel, and produce non-delay sensitive class businessSeize the situation of the uplink authorization resource of delay sensitive class business, fully ensured delay sensitive class businessFast transport.
