Fig. 3 is the flow chart of many subframe scheduling method the second embodiment of the present invention, and as shown in Figure 3, these many subframe scheduling methods comprise:
Step 201, the hybrid automatic repeat request (HARQ) number that continuous scheduling is indicated, first scheduling subframe is corresponding that receives many subframe schedulings of base station transmission and scheduling configuration parameter;
Step 201 specifically can comprise following situation:
The high-level signaling that carries continuous scheduling indication that situation one, reception base station send, described high-level signaling is for startup or the cancellation of the many subframe schedulings of notification terminal, and the Physical Downlink Control Channel that carries scheduling configuration parameter and hybrid automatic repeat request (HARQ) number corresponding to first scheduling subframe that receives that described base station sends;
Terminal can be from the high-level signaling of base station for example: many subframe schedulings start signalings and obtain the indication that many subframe schedulings start, and for example obtain continuous scheduling indication of this time scheduling simultaneously: the number of all continuous scheduling subframes or the number of scheduling subframe continuously after first scheduling subframe.And then the physical layer signaling by base station for example: Physical Downlink Control Channel obtains hybrid automatic repeat request (HARQ) number corresponding to first scheduling subframe.
Situation two, the described continuous scheduling indication that receives base station transmission, first Physical Downlink Control Channel of dispatching hybrid automatic repeat request (HARQ) number corresponding to subframe and dispatching configuration parameter.
Terminal can be first from the high-level signaling of base station for example: many subframe schedulings start signalings and obtain the indication that many subframe schedulings start, then from physical layer signaling for example: physical downlink control channel PDCCH is obtained scheduling configuration parameter, corresponding hybrid automatic repeat request (HARQ) number and the scheduling indication continuously of first scheduling subframe.Wherein, PDCCH for example can comprise downlink resource indication: DL scheduling, also for example can comprise ascending resource indication: UL grant, continuously scheduling indication can or be reused bit and obtain from the added bits of PDCCH, wherein reuses bit and can be redundancy versions territory in the downlink resource indication of PDCCH or the filler in ascending resource indication.
In addition, terminal can, according to the downlink transfer control information form in the Physical Downlink Control Channel receiving, determine that this time scheduling is single sub-frame scheduling or many subframe schedulings.For example: in downlink transfer, PDCCH adopts multiple Downlink Control Information (Downlink Control Information; Be called for short: DCI) form carries out descending scheduling transmission, in the situation that many subframe schedulings transmission mode is opened, can for the single sub-frame of new biography data, dispatch by reserved part DCI form, other DCI forms are for many subframe schedulings.The form of PDCCH comprises the DCI form 0 that carries out uplink scheduling; Also comprise the DCI form 1,1a, 1b, 1c, 2, the 2a, 3 that carry out scheduling downlink resource, carry out the downlink resource indication of different transmission mode.Wherein, DCI form 0, for uplink scheduling, comprising: scheduling of resource indication territory, new data indication territory, demodulated reference signal (Demodulation Reference Signal; Be called for short: DMRS) cyclic shift indication territory, modulating-coding indication territory, channel quality indication (Channel Quality Indicator; Be called for short: CQI) request domain, CRC (Cyclical Redundancy Check; Be called for short: CRC) territory etc.Other DCI forms, for downlink data dispatching indication, comprising: scheduling of resource indication territory, new data indication territory, modulating-coding indication territory, new data indication territory, power control indication territory, CRC check territory, HARQ process indication territory, redundancy versions indication territory etc.In part DCI form, there are 1 or 2 unused bits (bit), in order to meet the requirement of code check, be used as filling.Suppose that reserved DCI1a is as single sub-frame scheduling, extended formatting is as many subframe schedulings.In uplink, only have DCI form 0 for uplink scheduling, can increase other uplink schedulings DCI form in LTE-A agreement, according to the different DCI form of PDCCH, can judge current is to adopt single sub-frame scheduling, still adopts many subframe schedulings.
Step 202, according to described first hybrid automatic repeat request (HARQ) number corresponding to scheduling subframe and described continuous scheduling indication, obtain hybrid automatic repeat request (HARQ) number corresponding to current scheduling subframe, adopt described scheduling configuration parameter in described current scheduling subframe, to carry out the data packet transmission of corresponding hybrid automatic repeat request (HARQ) number;
Wherein, a packet of each scheduling subframe carrying of described many subframe schedulings, each scheduling subframe of described many subframe schedulings all adopts described scheduling configuration parameter.
If continuous scheduling indication comprises the number of all continuous scheduling subframes or dispatch continuously the number of subframe after first scheduling subframe, in base station, to terminal, issuing many subframe schedulings starts after signaling, according to hybrid automatic repeat request (HARQ) number corresponding to described first scheduling subframe and described continuous scheduling indication, obtain hybrid automatic repeat request (HARQ) number corresponding to current scheduling subframe, can comprise following example:
Example one, according to the number of described all continuous scheduling subframes or after first scheduling subframe the continuous number of scheduling subframe, from current available hybrid automatic repeat request (HARQ) number, choose minimum value as the hybrid automatic repeat request (HARQ) number of current scheduling subframe at every turn;
Example two, according to the number of described all continuous scheduling subframes or after first scheduling subframe the continuously number of scheduling subframe and hybrid automatic repeat request (HARQ) number corresponding to first scheduling subframe, according to order from small to large, choose successively current available hybrid automatic repeat request (HARQ) number as the hybrid automatic repeat request (HARQ) number of current scheduling subframe.
The present embodiment terminal receives scheduling configuration parameter, continuous scheduling indication and hybrid automatic repeat request (HARQ) number corresponding to first scheduling subframe that base station issues, and can realize many subframe schedulings, has saved the control signal expense of system, improves the spectrum efficiency of system.When retransmitting, adopt the single sub-frame scheduling can be better compatible with existed system, when retransmitting, the many subframe schedulings of employing can further reduce the expense of system control signaling, the performance of raising system.Adopt single PDCCH to carry out the data dispatch of a plurality of subframes, can reserve resource, when there is adjacent strong jamming community, can send interactive information by the control channel between base station, make to avoid in identical time scheduling data between the control channel of strong jamming community, thereby reduce the interference between control channel.
Fig. 4 a is the schematic diagram of the many subframe scheduling methods of the present invention the 3rd embodiment, and base station sends many subframe schedulings to UE and starts signaling, in order to indicating terminal, starts the data-transmission mode that many subframes receive and send.Many subframe schedulings start signaling can be by high-level signaling (for example: the signaling of MAC or rlc layer) issue, to new biography packet, configuration needs the number of sub-frames of scheduling each time, for example: the number of the subframe that each many subframe schedulings send continuously altogether or receive continuously, the scope of this number can be for being greater than 1, but the value that is less than or equal to the maximum HARQ process of system number, as 2,3,4,5,6,7,8 etc.Base station can be according to information such as the type of service of current transmission, community user number, subscriber channel situations, carry out continuous subframes scheduling configuration or change active user's corresponding configuration, by the information of high-level signaling notification terminal corresponding configuration change, terminal issues the moment of PDCCH according to base station, scheduling respective resources is carried out transfer of data.
In the embodiment of the present invention, terminal can obtain as scheduling indication continuously from the high-level signaling that receives or physical layer control signal, and from physical layer control signal, obtains the HARQ process number of scheduling configuration parameter, first scheduling subframe, the corresponding independent information such as ack/nack (ACK/NAK) feedback position.As shown in Fig. 4 a, in each many subframe schedulings process of supposing to configure, needing the moment of scheduling is continuously that number of sub-frames is 4, at first, be first subframe #0 constantly, terminal receives the PDCCH of the downlink transfer of base station transmission, wherein carry the information such as current HARQ process that PDCCH corresponding to first scheduling subframe is corresponding number, modulation coding mode, resource indication, subframe #0, subframe #1, subframe #2, subframe #3 that corresponding indication this time can be dispatched continuously.Now, first subframe #0 has PDCCH to issue, and 3 subframe #1, subframe #2, subframe #3 of follow-up continuous scheduling issue without PDCCH.In downlink transfer, bearing downlink resource indication (DL scheduling) in PDCCH, in DL scheduling, carrying the HARQ process number in first moment of many subframe schedulings, for example: at subframe #0, the HARQ process number of first subframe of base station configuration is " 0 ", UE can be according to this HARQ process number " 0 ", the size that can be subframe sequence number according to time sequencing is calculated the HARQ process number of the subframe issuing without PDCCH of the follow-up continuous scheduling of many subframe schedulings successively, for example: according to order from small to large, from current available HARQ process number, choose successively HARQ process number corresponding to follow-up each subframe, also can from current available HARQ process number, choose minimum value as the HARQ process number issuing without PDCCH subframe at every turn.
Base station, according to the timing relationship of downlink resource indication and downlink data transmission, uplink ACK/NAK information, can transmitted new biography packet in corresponding resource.Wherein, there are mapping relations in the resource location at uplink ACK/NAK information and PDCCH place.For the downlink data packet that has downlink resource indication, terminal can send according to PDCCH corresponding uplink ACK/NAK information in corresponding uplink ACK/NAK resource.For the subframe that there is no downlink resource indication, high-level signaling can be notified its transmission uplink ACK/NAK concrete channel position or the range of channels information of information for each UE.For example, by high-level signaling, notify UE when the descending new biography packet of subframe #1, subframe #2, subframe #3 transmission, corresponding uplink ACK/NAK information can be transmitted in the indicated uplink ACK/NAK resource of sub-frame of uplink #5, subframe #6, subframe #7.These uplink ACK/NAK resources are that base station is the reserved also notification terminal of terminal according to community user number and transmission packet, such as: can be by the corresponding concrete resource location of high-level signaling or physical layer signaling notice uplink ACK/NAK resource, resource number, corresponding information such as resource group, by other signalings, indicate again the concrete resource location of concrete corresponding uplink ACK/NAK information, or resource number.
As shown in Fig. 4 a, when many subframe schedulings for the first time, base station issues the downlink resource indication (DL scheduling) of the HARQ process #0 of carrying by PDCCH at subframe #0, for the data of dispatching current subframe #0, if the number of sub-frames of scheduling is 4 continuously, DL scheduling can also comprise HARQ process number and other configuration indications of subframe #1, subframe #2, subframe #3.If UE sends 4 subframes that are spaced apart of feedback information to base station, UE returns to uplink ACK/NAK information of the corresponding HARQ process number of downlink data to base station.Wherein, for HARQ process #0 and process #1, UE correctly transmits respectively the uplink ACK information of feedback to base station at subframe #4 and subframe #5.And for HARQ process #2 and process #3, in transmission, make a mistake, UE respectively at subframe #6 and subframe #7 to up NAK information corresponding to base station feedback.Therefore, need to retransmit the subframe of HARQ process #2 and process #3.For convenient, distinguish, in Fig. 4 a, the suffix of the process number that needs are retransmitted adds X.If adopt descending asynchronous adaptive retransmission, the PDCCH of retransfer scheduling can be the configuration of single sub-frame.In system, may, due to scheduling reason, subframe #8, subframe #9, subframe #10, subframe #11 not distributed to current terminal and carry out new biography data packet transmission.In the moment retransmitting at needs, if the corresponding moment of subframe does not have new biography allocation of packets to current terminal, terminal can judge that by the PDCCH receiving this packet is retransmission data packet may.In Fig. 4 a, suppose 4 subframes that are spaced apart of re-transmission, can to HARQ process #2 and process #3, retransmit respectively in subframe 9 and subframe 10.When base station is at subframe #12, many subframe schedulings of a new biography packet of configuration, carrying the downlink resource indication (DLscheduling) of available minimum HARQ process #0, indication issues new biography packet at this subframe #12, and continuous 4 subframes that comprise subframe #12 are as the use of new biography data packet transmission.Wherein, during each many subframe schedulings, UE can choose HARQ process number corresponding to current subframe according to order from small to large from current available HARQ process number, also can from current available HARQ process number, choose minimum value as the HARQ process number of current subframe at every turn.As shown in Fig. 4 a, subframe #15 can with HARQ process number comprise: " 1 " (discharging at subframe #5), " 4 " (discharging at subframe #8), " 7 " (discharging at subframe #11), if according to the method for order from small to large, because HARQ process number corresponding to the subframe #12 of a upper new biography packet is " 0 ", so HARQ process number corresponding to subframe #15 can be " 1 "; If according to the method for choosing minimum value, the HARQ process number that subframe #15 is corresponding can be also " 1 ".Supposing, is being that the HARQ process number that subframe #12 is corresponding is " 3 ", and, according to order from big to small, the HARQ process number that subframe #15 is corresponding can be " 4 ", and according to the order of minimum value, the HARQ process number that subframe #15 is corresponding can be " 1 ".
Further, in the process of many subframe schedulings, in indicating by resource, the new biography packet of the HARQ process number of indication may clash in same subframe with the retransmission data packet may that retransmits the HARQ process number of indicating in resource indication signaling, the retransmission data packet may of the HARQ process number that now, priority scheduling re-transmission resource indication signaling comprises.For example: in the process of many subframe schedulings for the second time of Fig. 4 a, base station issues the DL scheduling of the HARQ process #4 of carrying at subframe #4, also comprises the HARQ process number of continuous subframe #5, subframe #6, subframe #7.When the new biography data packet transmission of the HARQ of subframe #5 process #5 makes a mistake, UE returns to up NAK message to base station at subframe #9, base station can retransmit resource indication signaling at the DL scheduling of subframe #13 transmission retransfer scheduling, is used to indicate the scheduling to the retransmission data packet may of HARQ process #5.Now, formerly should be retransmitted and take for the subframe #13 of the transmission new biography packet of many subframe schedulings for the third time, at the next idle subframe #14 without retransmitting, can transmit the new biography packet of occupied sub-frame resources.If do not extend the number of sub-frames of continuous scheduling, this time many subframe schedulings can finish after the scheduling that completes 4 subframes, as shown in Fig. 4 a.If extend the number of sub-frames of scheduling continuously, this time many subframe schedulings can finish originally needing continuously the HARQ process number of scheduling to handle again, as shown in Figure 4 b, for extending the schematic diagram of scheduling number of sub-frames continuously in the many subframe scheduling methods of the present invention the 3rd embodiment, the script of many subframe schedulings need to take subframe #12 for the third time, #13, #14, #15, correspondence is dispatched HARQ process #0 respectively, #1, #4, the new biography packet of #7, at the former new biography packet that should transmitting HARQ process number #1 of subframe #13, but because base station has issued the re-transmission resource indication signaling of HARQ process #5 at subframe #13, therefore subframe #13 is taken by the retransmission data packet may of HARQ process #5, because base station has issued the re-transmission resource indication signaling of HARQ process #6 at subframe #14, therefore subframe #14 is taken by the retransmission data packet may of HARQ process #6, the dispatch delay of the new biography packet of HARQ process number #1 is processed to subframe #15, the dispatch delay of the new biography packet of HARQ process number #4 is processed to subframe #16, the dispatch delay of the new biography packet of HARQ process #7 is processed to subframe #17.
In addition under heterogeneous network scene, be the interference of avoiding strong jamming community to bring at ACK/NAK information or the PDCCH of feedback.Between the base station of neighbor cell, can occupy by the institute of inter-base station interface such as: the resource of the control channel of the mutual strong jamming of X2 interface community, the information such as delivery time, transmitting power, interference level relevant parameter, measurement result, base station can be that ACK/NAK resource or PDCCH carry out resource reservation according to mutual information, is used for the shared resource location of control channel of dispatching distribution current area.On the one hand can be according to the disturbed condition of neighbor cell, the ACK/NAK resource of Jiang Zhe community and other communities in actual physical resources for example: in frequency domain resource, dispatch, to avoid the interference in uplink between neighbor cell.For example: the resource of the control channel of the base station of the corresponding strong jamming of coordinated allocation community between this community and strong jamming community, such as: the physical layer control channels such as UL ACK/NAK, CQI, SRI, RACH or PDCCH, are distributed in the ACK/NAK information reconciliation of Yu Zhe community, strong jamming community on different frequency bands.On the other hand, it can be the reserved time-domain resource of PDCCH, by the X2 interface between base station, carry out the delivery time of the corresponding strong jamming of information interaction community PDCCH, to guarantee that corresponding strong jamming community PDCCH distributes constantly, thereby avoid in identical frequency band, sending PDCCH in strong jamming community in the same time in phase simultaneously.As shown in Fig. 4 a, owing to can sending the PDCCH of community #0 at subframe #0, at subframe #1, subframe #2, subframe #3, PDCCH can be sent, therefore the PDCCH of strong jamming community #1, community #2, community #3 can be sent respectively at subframe #1, subframe #2, subframe #3.Therefore,, when wireless network is arranged net, can determine transmission number of sub-frames continuously according to the number of strong jamming community.The terminal of corresponding community #0 is only carried out the reception of data at subframe #0, at subframe #1, subframe #2, subframe #3, can not carry out reception and the detection of PDCCH.
During PDCCH that the present embodiment base station issues to terminal, carry HARQ process number corresponding to first scheduling subframe of each many subframe schedulings and scheduling indication continuously, can realize many subframe schedulings, saved the control signal expense of system, improve the spectrum efficiency of system.When retransmitting, adopt the single sub-frame scheduling can be better and existed system compatibility.Adopt single PDCCH to carry out the data dispatch of a plurality of subframes, can also reserve resource, when there is adjacent strong jamming community, can send interactive information by the control channel between base station, make to avoid in identical time scheduling data between the control channel of strong jamming community, thereby reduce the interference between control channel.
Fig. 5 is the schematic diagram of the many subframe scheduling methods of the present invention the 4th embodiment, and base station sends high-rise many subframe schedulings startup signalings to UE and starts the data-transmission mode that many subframes receive and many subframes send that terminal is carried out.Different from the first embodiment, do not adopt high-level signaling notice scheduling number of sub-frames continuously, each many subframe schedulings by physical layer signaling for example: PDCCH carries continuous scheduling indication, the number of sub-frames that notification terminal uplink and downlink are dispatched continuously.Can adopt the mode of bitmap (bit map) mapping indicate the discontinuous subframe of required scheduling or adopt signaling to carry out the indication of continuous subframes number.In the present embodiment, take continuous subframes number as example, in PDCCH, can adopt added bits or reuse bit and carry resource indication, for example: the 2bits that can reuse redundancy versions territory (RV field) in downlink resource in PDCCH indication (DL scheduling) carries continuous scheduling indication, or increase more bit and carry continuous scheduling indication.In ascending resource indication (UL grant), can carry continuous scheduling indication by reusing existing filler (padding bit), or increase more bit and carry continuous scheduling indication.
With the descending example that is transmitted as, the continuous scheduling of many subframe schedulings indication can be expressed as: the i.e. number of scheduling subframe continuously after first scheduling subframe of the number of sub-frames of the continuous scheduling after the indicated subframe of PDCCH and then.When subframe #0, the resource indication DL scheduling of many subframe schedulings of carrying process #0, for example: in Fig. 5, in the process of many subframe schedulings, if scheduling is designated as " 4 " continuously in the DL scheduling of the PDCCH of subframe #0, represent the scheduling of resource of this PDCCH indication subframe #0, subframe #1, subframe #2, subframe #3, subframe #4.Can dispatch a plurality of subframes by a PDCCH, until terminal reaches its maximum HARQ process.If scheduling is designated as " 2 " continuously in the PDCCH of subframe #5, represent the scheduling of resource of this PDCCH indication subframe #5, subframe #6, subframe #7.In the HARQ process number territory (process number field) of carrying the PDCCH that the HARQ process number of many subframe schedulings can send from base station, obtain, the corresponding process number of current subframe scheduling packet is indicated in HARQ process number territory, and the packet that does not carry the subframe of PDCCH can be corresponding successively according to the HARQ order of available free.In existing LTE Release8 agreement, SPS transmits the not multiplexing transmission mode of support space, only supports the transmission mode of transmit diversity.Under many subframe schedulings mode, the activation that can carry out semi-persistent scheduling by more most static scheduling control channel forms is indicated, and carrys out the multiplexing transmission of support space.
Further, in many subframe schedulings process, can also adopt the indication retransmission information of the mode of many subframes.As shown in Figure 5, when HARQ process #4, process #5 make a mistake, UE will return to base station up NAK message, and HARQ process #4, process #5 need to retransmit, and the position of corresponding re-transmission subframe also can be indicated by the many subframe schedulings signaling in PDCCH.At subframe #12, base station issues the re-transmission resource indication signaling of HARQ process #4, process #5, the HARQ process number wherein carrying is " 4 ", retransmit and be designated as " 1 " continuously, except indication need to retransmit HARQ process #4, can also UE the acquisition subframe #13 that do not issue PDCCH need to retransmit the retransmission data packet may of HARQ process number #5.
During PDCCH that the present embodiment base station issues to terminal, carry HARQ process number and the scheduling indication continuously of the subframe of each current scheduling, can realize many subframe schedulings, saved the control signal expense of system, improve the spectrum efficiency of system.When retransmitting, the many subframe schedulings of employing can further reduce the expense of system control signaling, improve the performance of system.
In existing LTE agreement, defined dynamic dispatching (Dynamic Scheduling; Be called for short: DS) and semi-persistent scheduling (Semi-Persistent Scheduling; Be called for short: SPS) the resource indicating mode of two kinds of transfer of data.Under dynamic dispatching, each new biography data is for example surrounded by a corresponding control signal: PDCCH, and in order to notify its resource and transmission means.Subscriber equipment (User Equipment; Be called for short: UE) according to base station (Base Station; Be called for short: the PDCCH downlink data receiving, the transmit ascending data that BS) issue.PDCCH can take 1 to 3 OFDM (Orthogonal Frequency Division Multiplexing of corresponding several descending sub frames; Be called for short: the OFDM) resource of symbol: for bearing downlink resource indication (DL scheduling) or downlink resource indication (UL grant), be used to indicate corresponding lower uplink.The shared OFDM symbol numbers of PDCCH, according to the number of institute's dispatched users number in community, can be adjusted in base station.When fewer when PDCCH takies OFDM symbol, the resource that can carry data is more, and corresponding system spectral efficiency is higher; PDCCH takies resource when more, and the resource of carrying valid data is fewer, and system spectral efficiency is lower.Under semi-persistent scheduling mode, base station only sends a descending control signaling (PDCCH) when starting semi-persistent scheduling transmission, UE is according to the indicated position of this PDCCH and start SPS transmission constantly, UE carries out transmission and the reception of new biography packet according to certain intervals, until receive the PDCCH of a special format, stop SPS transmission again.
Because dynamic dispatching and semi-persistent scheduling are all to use PDCCH to notify, it is dynamic dispatching or semi-persistent scheduling that the different I D of UE by the upper scrambling of CRC of PDCCH can distinguish this time scheduling.Wherein, the CRC of the PDCCH of dynamic dispatching carries out scrambling by C-RNTI; The CRC of the PDCCH of semi-persistent scheduling carries out scrambling by SPS-C-RNTI.When UE detects the PDCCH of SPS-C-RNTI scrambling, know and start this time semi-static transmission, according to reception indicated in PDCCH or transmission data, within a period of time, according to the indicated position of the PDCCH of the semi-static transmission of primary startup, receive or send data, do not need all by PDCCH, to notify the resource location of SPS packet at every turn, when needs change SPS resource location, in the moment periodically arriving in SPS data, can adopt the configuration of the PDCCH of the new configuration semi-persistent scheduling before replacing.Until the PDCCH of the SPS-C-RNTI scrambling of a special format cancels this semi-static transmission.In existing protocol, stipulate that descending and value uplink semi-persistent scheduling interval can be 10,20,32,40,65,80,128,160,320,640, this interval shows to connect the interval between a semi-static data bag transmission.
New biography packet under dynamic dispatching, the data resource of each subframe transmission, in corresponding ascending-descending subframes, needs corresponding PDCCH the data configuration of transmission to be carried out to the indication of corresponding resource location and other configurations.Therefore,, when existing continuous new biography data to transmit, on corresponding descending sub frame, the PDCCH that need to carry corresponding uplink and downlink packet number indicates.For data retransmission, in uplink, can adopt synchronous non-self-adapting HARQ mechanism to carry out retransmission process, adopt the retransmission data packet may of this mechanism can be according to HARQ regularly in corresponding subframe, according to the respective resources that is configured in of transmission last time, send upstream data, and do not need the PDCCH of data retransmission; For the data retransmission of up adaptive retransmission and downlink data, need PDCCH to retransmit resource indication signaling.
Fig. 6 is the schematic diagram of the many subframe scheduling methods of the present invention the 5th embodiment, as shown in Figure 6, when semi-persistent scheduling, adopts the PDCCH of SPS-C-RNTI scrambling can carry out the activation of uplink and downlink semi-persistent scheduling.Semi-static subframe scheduling interval n and/or semi-persistent scheduling transmission length m that base station can notify UE to start by high-level signaling.Wherein semi-persistent scheduling transmission length m is the continuous scheduling indication in above-described embodiment.The subframe original position that the moment issuing of supposing to take PDCCH is semi-persistent scheduling, is spaced apart n with semi-persistent scheduling, for terminal scheduling m time and the resource that activates the identical configuration of PDCCH for example: HARQ process, then discharges corresponding resource.When if system is not notified semi-persistent scheduling transmission length m, can carry out resource release indication by discharging the PDCCH of semi-persistent scheduling.
For example: for the first time during many subframe schedulings, semi-persistent scheduling transmission length parameter m is " 3 ", when semi-static subframe scheduling interval n is " 2 ", as shown in Figure 6, at subframe #0, issue the PDCCH that activates semi-persistent scheduling, its HARQ process number is " 0 ", therefore at the corresponding new biography packet of subframe #0 transmitting HARQ process #0, during according to semi-static subframe scheduling interval n=2, need one, interval subframe, at the upper once subframe #2 transmitting HARQ process #1 corresponding data of transmission, equally, at the new biography packet of subframe #4 corresponding HARQ instance process #2.After 3 end of transmissions, this time the PDCCH of semi-persistent scheduling cancels.During many subframe schedulings, base station can reconfigure corresponding m=4 and n=2 for the second time, and the PDCCH that issues new semi-persistent scheduling carries out this time transmission indication.For example: at subframe #5, send new PDCCH, wherein HARQ process number is " 3 ", according to corresponding configuration, transmit, now, at subframe #5, carry out the transmission of HARQ process #3, at subframe #7, carry out the transmission of HARQ process #4, due at subframe #4, the uplink ACK information corresponding to HARQ process #0 of feedback, acquiescence HARQ process #0 is released, therefore at upper once transmission time subframe #9, can from current available HARQ process number, choose the new biography packet of HARQ process #0 corresponding to transmission minimum value " 0 ".Due to HARQ process, #1 is not released, and supposes that retransmitting is regularly 4 subframes, at subframe #10, can carry out by carrying the PDCCH of re-transmission resource indication signaling the retransfer scheduling of HARQ process #1.Wherein, semi-static subframe scheduling interval n can be set to the different numerical value such as 1,2,3,4,5, semi-persistent scheduling transmission length m can equal the maximum HARQ process of system numerical example as: 1 to 15.
During PDCCH that the present embodiment base station issues to terminal, carry the HARQ process number of the subframe of each current scheduling, continuous scheduling indication and semi-static subframe scheduling interval, can under the mode of semi-persistent scheduling, realize many subframe schedulings, save the control signal expense of system, improved the spectrum efficiency of system.When retransmitting, the many subframe schedulings of employing can further reduce the expense of system control signaling, improve the performance of system.
