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 inserts high speed downlink packet and inserts (High SpeedDownlink Packet Access, abbreviate HSDPA as) be third generation partner program (3rd Generation Partnership Project, abbreviate 3GPP as) a kind of technology of in version 5 (Release-5), proposing, be used to improve the network data throughput of down direction (network is to terminal), the descending peak rate of its design can reach 14.4Mbps.
On physical layer design, HSDPA uses high speed-Physical Downlink Shared Channel (High Speed Physical Downlink Shared Channel at down direction, abbreviate HS-PDSCH as), be used to carry the data of high speed descending sharing channel (High Speed DownlinkShared Channel abbreviates HS-DSCH as); Simultaneously, also use High-Speed Shared Control Channel (High Speed Shared Control Channel at down direction, abbreviate HS-SCCH as), before sending, corresponding HS-PDSCH sends, be used to notify terminal (User Equipment, abbreviate UE as) some necessary informations of the HS-PDSCH of transmission after HS-SCCH, comprise employed spreading code, modulator approach, the transmission block size, mix repeat requests (Hybrid Automatic Repeat Request, abbreviate HARQ as) process, redundancy versions, the new data indication, the UE sign, thereby the UE by the appointment of UE sign can correctly receive the data that sent, and other UE then can't correctly receive this data.At up direction, HSDPA uses the High-Speed Dedicated Physical Control Channel (High Speed Dedicated Physical Control Channel abbreviates HS-DPCCH as) of HS-DSCH.By this control channel, whether UE correctly receives a transmission block among the HS-DSCH to network-feedback, acknowledge character (Acknowledgement, abbreviate ACK as) for correctly receiving, non-acknowledge character (Non-Acknowledgement, abbreviate NACK as) for correctly not receiving, corresponding data need to retransmit, and network retransmits or sends new data in view of the above.Simultaneously, UE also feeds back a channel quality indication (ChannelQuality Indication abbreviates CQI as).The CQI table is predefined, and each CQI value is corresponding to the HS-DSCH subframe of a fixed transport block size, HS-PDSCH number, modulator approach.UE should feed back the CQI of a maximum, if represent that the HS-DSCH subframe of this CQI correspondence begins to transmit preceding 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%, with this reference as this UE quality of wireless channel.
In the design of HS-DPCCH, there are 10 bit data to be used to carry HARQ-ACK information, there are 20 to be used to carry CQI information in addition.Each UE belongs to certain specific classification (UE Category) according to the ability difference, and totally 31 in its corresponding CQI table can be represented with 5 bit data, is encoded into 20, is mapped to the CQI bit field of HS-DPCCH.There are two kinds of situations of ACK/NACK in HARQ, and expression correctly receives data block and there is mistake in the data block that receives respectively, and is 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 (Multiple Input Multiple Output abbreviates MIMO as) antenna technology is wherein a kind of method that improves the wireless channel transmission bandwidth.3GPP has adopted the MIMO technology at Rel-7, allows to transmit simultaneously maximum two transmission blocks (main transmission block and auxilliary transmission block) and give same UE in a 2ms Transmission Time Interval (Transmission TimeInterval abbreviates TTI as).For supporting the MIMO technology, transmitting terminal need modulate data on two incoherent antennas and send simultaneously, and the recipient also needs to receive data simultaneously from two incoherent antennas, and carries out demodulation.The MIMO technology improves bandwidth by increasing number of antennas simultaneously transmit leg and recipient.If do not adopt the MIMO technology, also can adopt the method that increases carrier wave to improve bandwidth.3GPP has introduced dual carrier HSDPA technology (Double Carrier HSDPA abbreviates DC-HSDPA as) at Rel-8, utilizes two descending adjacent carriers (main carrier and auxilliary carrier wave) to improve downlink bandwidth.Main carrier corresponding with service HS-DSCH sub-district, the corresponding auxilliary service HS-DSCH of auxilliary carrier wave sub-district.Main carrier and auxilliary carrier wave are provided with HS-PDSCH and HS-SCCH respectively simultaneously, and independently dispatch.For having the UE that receives the DC-HSDPA ability, can receive the HSDPA data at downlink main carrier to carry and descending auxilliary carrier wave simultaneously.
Main carrier and auxilliary carrier wave are different in the use.Main carrier is for a UE, always is in state of activation, and the activation of auxilliary carrier wave also is subjected to the control of network whether except the two carrier processing abilities that depend on UE.For improving the response speed that auxilliary carrier wave activates deexcitation, network is controlled the activation and the deexcitation of auxilliary carrier wave by a physical layer command HS-SCCH Order (high-speed shared control channel command).
At up direction (terminal to network), 3GPP has proposed High Speed Uplink Packet access (High Speed Uplink Packet Access in Rel-6, abbreviate HSUPA as), be used to improve the cell throughout and the user rate of up direction, the up peak rate of its design can reach 5.8Mbps.On physical layer design, HSUPA uses at up direction and strengthens Dedicated Physical Data Channel (Enhanced Dedicated Physical Data Channel, abbreviate E-DPDCH as), be used for the data that carrying strengthens dedicated channel (Enhanced DedicatedChannel abbreviates E-DCH as); Simultaneously, also use enhancing Dedicated Physical Control Channel (Enhanced Dedicated Physical Control Channel at up direction, abbreviate E-DPCCH as), be used for transmitting some control informations, comprise re-transmission sequence number, strengthen transformat combination indication (Enhanced Transmission Format CombinationIndication abbreviates E-TFCI as) and happy bit.In addition, the scheduling of resource of HSUPA is finished jointly by Node B (NodeB) and UE, UE remains advisory NodeB by schedule information with own up-to-date buffer state, power, and tells by the happy bit whether NodeB is satisfied with to the mandate that current NodeB gives; NodeB takes all factors into consideration the above-mentioned information of UE report then according to the ascending resource operating position of sub-district etc., gives UE certain mandate, i.e. the UE maximum power that can send.The enhancing absolute grant channel (Enhanced Access Grant Channel abbreviates E-AGCH as) or the wild phase assigned by down direction of authorizing are finished authorization channel (Enhanced Relative GrantChannel abbreviates E-RGCH as).In addition, set up enhancing HARQ indicating channel (E-DCH Hybrid ARQ Indicator Channel abbreviates E-HICH as) at down direction, whether NodeB correctly receives by the data block that E-HICH feedback UE sends.
Similar with down direction, 3GPP is also constantly carrying out the enhancing of up direction on the Rel-6HSUPA basis.After Rel-8 finishes DC-HSDPA, as with the coupling of DC-HSDPA, 3GPP has introduced two carrier wave HSUPA (DC-HSUPA) at Rel-9, utilizes two up adjacent carriers (main carrier and auxilliary carrier wave) to improve upstream bandwidth.Up main carrier and upstream auxiliary carriers are provided with E-DPDCH and E-DPCCH separately respectively, and downlink main carrier to carry and descending auxilliary carrier wave are provided with E-AGCH, E-RGCH and E-HICH separately respectively.Up main carrier is corresponding with downlink main carrier to carry, and upstream auxiliary carriers is corresponding with descending auxilliary carrier wave.Main carrier and auxilliary carrier wave are independently dispatched.For having the UE that sends the DC-HSUPA ability, can send the HSUPA data at up main carrier and upstream auxiliary carriers simultaneously.
Similar with down direction, up main carrier and upstream auxiliary carriers are also different in the use.Up main carrier is for a UE, always is in state of activation, and the activation of upstream auxiliary carriers also is subjected to the control of network whether except the two carrier processing abilities that depend on UE.For improving the response speed of activating upstream auxiliary carriers deexcitation, network also is activation and the deexcitation of controlling upstream auxiliary carriers by a physical layer command HS-SCCH Order.Activating different with descending auxilliary carrier wave is that upstream auxiliary carriers does not allow to activate under the situation of descending auxilliary carrier wave deexcitation.
The HS-SCCH Order here is the order that sends to UE by the HS-SCCH channel, comprising, Order type (3 bit), Order (3 bit) and UE identify (16 bit).Used part of O rder type and Order definition at present, seen the following form shown in 1.
Table 1HS-SCCH Order
In the signal of last table 1, Order type is three bits, ' 000 ' is used for activating or the discontinuous reception of deexcitation (Discontinuous Reception, abbreviate DRX as), discontinuous transmission (Discontinuous Transmission abbreviates DTX as) or HS-SCCH-less operation and notice HS-DSCH Serving cell change.Among the Order, x_ord, 1=' 1 ' and expression activation DRX, ' 0 ' expression deexcitation DRX; X_ord, 2=' 1 ' expression activation DTX, ' 0 ' expression deexcitation DTX; X_ord, 3=' 1 ' expression activation HS-SCCH-less operation, ' 0 ' expression deactivating HS-SCCH-less operation; If this order sends from non-service cell, and order=' 000 ', represent that then the HS-DSCH Serving cell changes.
Order type=' 001 ' is used for activating or descending auxilliary carrier wave of deexcitation or upstream auxiliary carriers.Order='-00 ' expression descending auxilliary carrier wave of deexcitation and upstream auxiliary carriers, '-01 ' expression activates descending auxilliary carrier wave and deexcitation upstream auxiliary carriers, and '-11 ' expression activates descending auxilliary carrier wave and upstream auxiliary carriers.Other order definition keeps.
In order further to improve user's peak rate, more carrier combination need be transmitted together, such as in the enterprising line data transmission of the frequency band of 20MHz, just need will reach four carrier combination together.When the activation of carrying out carrier wave or deexcitation control, for the situation of a main carrier and an auxilliary carrier wave, two bits just are enough to descending auxilliary carrier wave and upstream auxiliary carriers activates flexibly or deexcitation control among the HS-SCCH Order.But, for the situation of multicarrier more, for example, the situation of main carrier and two auxilliary carrier waves, a main carrier and three auxilliary carrier waves, there is various form in the configuration mode of its carrier wave.
Fig. 1 is the schematic diagram according to three carrier waves in the system of correlation technique or the configuration of four carrier system carrier waves, as shown in Figure 1, a plurality of carrier waves can be on maximum two frequency ranges, and a plurality of carrier waves in same frequency range must be adjacent, and main carrier can be any one in a plurality of carrier waves that disposed.Down direction can dispose 4 carrier waves at most, according to its centre frequency be designated as from small to large F1, F2, F3, F4}, corresponding up-link carrier also is designated as { F1, F2, F3, F4}.Figure acceptance of the bid ' carrier wave of C ' is the carrier wave that has disposed in the system.
Fig. 2 is the schematic diagram that activates according to carrier wave in three carrier waves of correlation technique or four carrier systems, shown in Fig. 2 (01) and (02), under every kind of carrier wave configuration scene, the activation of auxilliary carrier wave has different compound modes again, Fig. 2 signal has provided the situation of two carrier waves of up maximum activation and two essential four carrier waves of adjacent, descending maximum activation of carrier wave, the figure acceptance of the bid ' carrier wave of A ' is the carrier wave that system activates certain UE.Owing to there are a plurality of auxilliary carrier waves, network and the terminal auxilliary carrier wave in must clear and definite HS-SCCH Order refer in a plurality of auxilliary carrier waves which or which.Although all be to activate 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.
3GPP RAN1#59 meeting manuscript R1-094760 discloses a kind of method according to the auxilliary carrier wave of auxiliary carrier frequency rate size order sign, according to this method, need 20 kinds of different instructions of HS-SCCH Order definition to distinguish all the auxilliary carrier waves activation shown in Figure 2 and the situation of deexcitation.But the instruction that this mode adopts is more, causes upstream auxiliary carriers and descending auxilliary carrier wave activates or the physical channel bit number that uses during the flexible control of deexcitation is many.
