Description
Technical field
The present invention relates to the communications field, in particular to a kind of carrier control method and device.
Background technology
High-speed downlink packet access high-speed slender body theory (HighSpeedDownlinkPacketAccess, referred to as HSDPA) be third generation partner program (3rdGenerationPartnershipProject, referred to as 3GPP) in the middle a kind of technology proposed of version 5 (Release-5), for improving the network data throughput of down direction (network is to terminal), the downlink peak rates of its design can reach 14.4Mbps.
In physical layer design, HSDPA uses High Speed-Physical DSCH Downlink Shared Channel (HighSpeedPhysicalDownlinkSharedChannel at down direction, referred to as HS-PDSCH), for carrying the data of high speed descending sharing channel (HighSpeedDownlinkSharedChannel, referred to as HS-DSCH), simultaneously, High-Speed Shared Control Channel (HighSpeedSharedControlChannel is also used at down direction, referred to as HS-SCCH), sent before corresponding HS-PDSCH sends, for notification terminal (UserEquipment, referred to as UE) some necessary informations of HS-PDSCH of sending after HS-SCCH, comprise used spreading code, modulator approach, transmission block size, mixing repeat requests (HybridAutomaticRepeatRequest, referred to as HARQ) process, redundancy versions, new data indicates, UE identifies, thus identify by UE the UE specified and can correctly receive sent data, other UE then cannot correctly receive this data.At up direction, HSDPA uses a High-Speed Dedicated Physical Control Channel (HighSpeedDedicatedPhysicalControlChannel, referred to as HS-DPCCH) of HS-DSCH.By this control channel, whether UE correctly receives a transmission block in HS-DSCH to network-feedback, acknowledge character (Acknowledgement, referred to as ACK) for correctly to receive, non-acknowledgement character (Non-Acknowledgement, referred to as NACK) for correctly not receive, corresponding data need to retransmit, and network carries out retransmitting or sending new data accordingly.Meanwhile, UE also feeds back channel quality instruction (ChannelQualityIndication, referred to as CQI).CQI table is predefined, and each CQI value corresponds to the HS-DSCH subframe of a fixed transport block size, HS-PDSCH number, modulator approach.UE should feed back a maximum CQI, if represent that HS-DSCH subframe that this CQI is corresponding starts to transmit front 1 time slot in the HS-DPCCH subframe of carrying CQI and received by this UE, so, the error probability of corresponding transmission block is no more than 10%, in this, as the reference of this UE quality of wireless channel.
In the design of HS-DPCCH, there are 10 bit data for carrying HARQ-ACK information, have 20 in addition for carrying CQI information.Each UE is different according to ability, belongs to certain specific classification (UECategory), and totally 31, the CQI table of its correspondence, can represent by 5 bit data, be encoded into 20, be mapped to the CQI bit field of HS-DPCCH.There are ACK/NACK two kinds of situations in HARQ, represents respectively correctly to receive data block and the data block that receives exists mistake, and be encoded into 10 by specific code book, is mapped to the HARQ-ACK bit field of HS-DPCCH.
Subsequently, on the basis of HSDPA, 3GPP strengthens from many aspects.Multiple-input and multiple-output (MultipleInputMultipleOutput, referred to as MIMO) antenna technology is a kind of wherein method improving wireless channel transmission bandwidth.3GPP have employed MIMO technology at Rel-7, allow in a 2ms Transmission Time Interval (TransmissionTimeInterval, referred to as TTI), to transmit maximum two transmission blocks (main transmission block and auxiliary transmission block) to same UE simultaneously.For supporting MIMO technology, transmitting terminal needs to modulate data on two incoherent antennas and sends simultaneously, and recipient also needs to receive data from two incoherent antennas simultaneously, and carries out demodulation.MIMO technology improves bandwidth by increasing number of antennas at transmit leg and recipient simultaneously.If do not adopt MIMO technology, the method increasing carrier wave also can be adopted to improve bandwidth.3GPP introduces dual carrier HSDPA technology (DoubleCarrierHSDPA, referred to as DC-HSDPA) at Rel-8, utilizes two descending adjacent carriers (main carrier and auxiliary carrier wave) to improve downlink bandwidth.Main carrier corresponding with service HS-DSCH community, the corresponding auxiliary serving HS-DSCH cell of auxiliary carrier wave.Main carrier and auxiliary carrier wave arrange HS-PDSCH and HS-SCCH respectively simultaneously, and independently dispatch.For having the UE receiving DC-HSDPA ability, HSDPA data can be received at downlink main carrier to carry and descending auxiliary carrier wave simultaneously.
Main carrier and auxiliary carrier wave are different in use.Main carrier for a UE, is always in state of activation, and the activation of auxiliary carrier wave is whether except the two carrier processing abilities depending on UE, is also subject to network-based control.For improving the response speed of auxiliary carrier activation deexcitation, network controls activation and the deexcitation of auxiliary carrier wave by a physical layer command HS-SCCHOrder (high-speed shared control channel command).
At up direction (terminal to network), 3GPP proposes High Speed Uplink Packet access (HighSpeedUplinkPacketAccess in Rel-6, referred to as HSUPA), for improving cell throughout and the user rate of up direction, the upstream peak speed of its design can reach 5.8Mbps.In physical layer design, HSUPA uses at up direction and strengthens Dedicated Physical Data Channel (EnhancedDedicatedPhysicalDataChannel, referred to as E-DPDCH), for carrying the data strengthening dedicated channel (EnhancedDedicatedChannel, referred to as E-DCH); Simultaneously, also use at up direction and strengthen Dedicated Physical Control Channel (EnhancedDedicatedPhysicalControlChannel, referred to as E-DPCCH), be used for transmitting some control informations, comprise re-transmission sequence number, strengthen transformat combination instruction (EnhancedTransmissionFormatCombinationIndication, referred to as E-TFCI) and happy bit.In addition, the scheduling of resource of HSUPA is completed jointly by Node B (NodeB) and UE, oneself up-to-date buffer state, power residue situation are notified NodeB, and tell whether NodeB is satisfied with the mandate that current NodeB gives by happy bit by schedule information by UE; NodeB, then according to the ascending resource service condition etc. of community, considers the above-mentioned information of UE report, gives the mandate that UE is certain, i.e. the UE maximum power that can send.Enhancing absolute grant channel (the EnhancedAccessGrantChannel assigned by down direction authorized, referred to as E-AGCH) or strengthen Relative Grant Channels (EnhancedRelativeGrantChannel, referred to as E-RGCH) complete.In addition, set up strengthen HARQ indicating channel (E-DCHHybridARQIndicatorChannel, referred to as E-HICH) at down direction, whether the data block that NodeB feeds back UE transmission by E-HICH correctly receives.
Similar with down direction, 3GPP also constantly carries out the enhancing of up direction on Rel-6HSUPA basis.After Rel-8 completes DC-HSDPA, as with the mating of DC-HSDPA, 3GPP introduces two carrier wave HSUPA (DC-HSUPA) at Rel-9, utilizes two up adjacent carriers (main carrier and auxiliary carrier wave) to improve upstream bandwidth.Up main carrier and upstream auxiliary carriers arrange respective E-DPDCH and E-DPCCH respectively, and downlink main carrier to carry and descending auxiliary carrier wave arrange respective E-AGCH, E-RGCH and E-HICH respectively.Up main carrier is corresponding with downlink main carrier to carry, and upstream auxiliary carriers is corresponding with descending auxiliary carrier wave.Main carrier and auxiliary carrier wave are independently dispatched.For having the UE sending DC-HSUPA ability, HSUPA data can be sent at up main carrier and upstream auxiliary carriers simultaneously.
Similar with down direction, up main carrier and upstream auxiliary carriers are also different in use.Up main carrier for a UE, is always in state of activation, and the activation of upstream auxiliary carriers is whether except the two carrier processing abilities depending on UE, is also subject to network-based control.For improving the response speed of activating upstream auxiliary carriers deexcitation, network is also the activation and the deexcitation that are controlled upstream auxiliary carriers by a physical layer command HS-SCCHOrder.Different with descending auxiliary carrier activation, upstream auxiliary carriers is do not allow to activate when descending auxiliary carrier wave deexcitation.
Here HS-SCCHOrder is the order sent to UE by HS-SCCH channel, comprising, Ordertype (3 bit), Order (3 bit) and UEidentify (16 bit).Employ part Ordertype and Order definition at present, seen the following form shown in 1.
Table 1HS-SCCHOrder
In the signal of upper table 1, Ordertype is three bits, ' 000 ' is for activating or the discontinuous reception (DiscontinuousReception of deexcitation, referred to as DRX), discontinuous transmission (DiscontinuousTransmission, referred to as DTX) or HS-SCCH-less operation and notice HS-DSCH Serving cell change.In Order, x_ord, 1=' 1 ' represents activates DRX, and ' 0 ' represents deexcitation DRX; X_ord, 2=' 1 ' represents activates DTX, and ' 0 ' represents deexcitation DTX; X_ord, 3=' 1 ' represents activates HS-SCCH-less operation, and ' 0 ' represents deactivating HS-SCCH-less operation; If this order sends from non-service cell, and order=' 000 ', then represent that HS-DSCH Serving cell changes.
Ordertype=' 001 ' is for activating or the descending auxiliary carrier wave of deexcitation or upstream auxiliary carriers.Order='-00 ' represents the descending auxiliary carrier wave of deexcitation and upstream auxiliary carriers, and '-01 ' represents activates descending auxiliary carrier wave and deexcitation upstream auxiliary carriers, and '-11 ' represent activates descending auxiliary carrier wave and upstream auxiliary carriers.Other order definition retains.
In order to improve user's peak rate further, needing more carrier combination to transmit together, such as on the frequency band of 20MHz, carrying out transfer of data, just need will reach four carrier combination together.When carrying out the activation of carrier wave or deexcitation controls, for the situation of a main carrier and an auxiliary carrier wave, in HS-SCCHOrder, two bits are just enough to activate flexibly descending auxiliary carrier wave and upstream auxiliary carriers or deexcitation controls.Such as, but for the situation of more multicarrier, the situation of a main carrier and two auxiliary carrier waves, a main carrier and three auxiliary carrier waves, there is various form in the configuration mode of its carrier wave.
Fig. 1 is the schematic diagram of three carrier waves or the configuration of four carrier system carrier waves in the system according to correlation technique, as shown in Figure 1, multiple carrier wave can in maximum two frequency ranges, and the multiple carrier waves in same frequency range must be adjacent, and main carrier can be any one in configured multiple carrier waves.Down direction can configure at most 4 carrier waves, is designated as that { F1, F2, F3, F4}, corresponding up-link carrier is also designated as { F1, F2, F3, F4} according to its centre frequency from small to large.Figure acceptance of the bid ' carrier wave of C ' is the carrier wave be configured with in system.
Fig. 2 is the schematic diagram according to carrier activation in three carrier waves of correlation technique or four carrier systems, as shown in Fig. 2 (01) and (02), under often kind of carrier wave configuration scene, the activation of auxiliary carrier wave has again different compound modes, Fig. 2 signal gives up maximum activation two carrier waves and the situation of required adjacent, descending maximum activation four carrier waves of two carrier waves, figure acceptance of the bid ' carrier wave of A ' is the carrier wave that system activates certain UE.Owing to there is multiple auxiliary carrier wave, network and the terminal auxiliary carrier wave must specified in HS-SCCHOrder refer in multiple auxiliary carrier wave which or which., although be all activation 4 descending carriers and 2 up-link carriers, there are three kinds of different situations in situation 28,29 and 30 as shown in Figure 2.
3GPPRAN1#59 meeting manuscript R1-094760 discloses a kind of method identifying auxiliary carrier wave according to auxiliary carrier frequency rate size order, according to the method, need HS-SCCHOrder to define situation that 20 kinds of different instructions come all auxiliary carrier activation shown in component-bar chart 2 and deexcitation.But the instruction that this mode adopts is more, cause the physical channel bit number that uses when controlling upstream auxiliary carriers and descending auxiliary carrier activation or deexcitation flexible many.
