Embodiment
For make purpose of the present invention, technical scheme, and advantage clearer, below in conjunction with the accompanying drawing embodiment that develops simultaneously, technical scheme provided by the invention is described in further detail.
Referring to Fig. 1, the method flow diagram that control channel sends under a kind of uplink multi-carrier pattern that provides for the embodiment of the invention comprises:
By each the enhancing dedicated channel E-DCH under the uplink multi-carrier pattern is disposed respectively corresponding control channel on down link, with the control channel of described configuration when a descending carrier sends, so that UE can support the pattern of descending single carrier+uplink multi-carrier, and be conducive to the pattern switching of easy UE between downlink double/multi-load ripple+uplink multi-carrier pattern and descending single carrier+uplink multi-carrier pattern; And UE only need monitor a descending carrier, saves UE monitor channel on other descending carrier, is conducive to the power saving of UE, so the technical scheme that provides of the embodiment of the invention can adapt to the development of uplink multi-carrier pattern.
To each up-link carrier of user equipment (UE) under the uplink multi-carrier pattern, the corresponding dedicated channel E-DCH that strengthens of configuration in up link.Each E-DCH to configuration needs to increase one group of physical channel newly for user equipment (UE) at down link: E-DCH absolute grant channel E-AGCH, E-DCH relative authorization channel E-RGCH and E-DCH hybrid automatic repeat request indication channel E-HICH.
In one embodiment of the invention, at least following scheme can be arranged to each E-DCH of user equipment (UE) at down link configuration (sending in other words) E-DCH relative authorization channel E-RGCH and E-DCH hybrid automatic repeat request indication channel E-HICH:
To the identical channel code of E-HICH configuration of each E-DCH of user equipment (UE), different signature sequence number; To the different signature sequence of the E-RGCH configuration of each E-DCH of user equipment (UE) number, and for number being different from, the signature sequence of described E-RGCH configuration is the signature sequence of described E-HICH configuration number.Perhaps
To the different channel code of E-HICH configuration of each E-DCH of user equipment (UE), identical or different signature sequence number; To the identical or different signature sequence of the E-RGCH configuration of each E-DCH of user equipment (UE) number, and be that the E-RGCH of same E-DCH and signature sequence that E-HICH disposes are number different.
By above allocation plan to E-RGCH and E-HICH, no matter the E-HICH channel of each E-DCH E-DCH that uses identical or different channel code can carry out simultaneously a plurality of up-link carriers in down link dispatches, and has improved the flexibility of the E-DCH scheduling of up-link carrier.
Usually, the E-HICH of the same E-DCH of user equipment (UE) and the identical channel code of E-RGCH configuration, therefore, if to the E-HICH of each E-DCH of the user equipment (UE) signature sequence different with the E-RGCH configuration number, the E-HICH of the E-DCH of user equipment (UE) and E-RGCH can share a code channel.So not only reduced the quantity of the descending carrier of user equipment (UE) monitoring, the code resource that can also save down link.
In another embodiment, at least following scheme can be arranged to each E-DCH of user equipment (UE) at down link configuration (sending in other words) E-AGCH:
To the identical channel code of E-AGCH configuration of each E-DCH of user equipment (UE), different E-RNTI.Perhaps
To the different channel code of E-AGCH configuration of each E-DCH of upper user equipment (UE), identical or different E-RNTI.
More than in the allocation plan to E-AGCH, if the E-AGCH of each E-DCH distinguishes with identical channel code, different E-RNTI, when a descending carrier sends E-AGCH, can avoid conflict by time division multiplexing.Like this, not only can reduce the quantity of the descending carrier of monitoring, be conducive to the power saving of UE; Can also save the code resource of down link.
More than in the allocation plan to E-AGCH, if the E-AGCH of each E-DCH distinguishes with different channel codes, identical E-RNTI, can send many E-AGCH channels at a descending carrier.Like this, UE can reduce the quantity of the descending carrier of monitoring, is conducive to the power saving of UE.
Dispose E-HICH and E-RGCH control channel by each E-DCH that gives UE, and by each E-DCH configuration E-AGCH control channel to UE, so that UE can support the uplink multi-carrier pattern.
It will be appreciated by persons skilled in the art that the channel parameter that network side need to use the control channel of each E-DCH of UE sends to UE.For E-HICH and E-RGCH, channel code and the signature sequence notice UE that E-HICH and the E-RGCH of each E-DCH can be used; For E-AGCH, the channel code that the E-AGCH of each E-DCH can be used and E-RNTI notice UE.
Particularly, can be by network side, universal land radio access web (Universal TerrestrialRadio Access Network for example, UTRAN) pass through high-level signaling, for example Radio Resource is controlled (RadioResource Control, RRC) channel code (E-RGCH also uses this channel code) that uses of the E-HICH of each E-DCH of message informing UE and signature sequence number, the signature sequence of the E-RGCH use of each E-DCH of UE number; And the employed channel code of the E-AGCH of each E-DCH of UE and E-RNTI.
Need to prove, support that at UE under the pattern of downlink double/multi-load ripple, the technical scheme that control channel sends under the uplink multi-carrier pattern that the embodiment of the invention provides can be chosen a descending carrier wantonly and send; And technical scheme provided by the invention is not restricted to only send at a descending carrier, equally also can choose plural descending carrier wantonly and send.
The method that the control channel that the below provides the embodiment of the invention as an example of up two carrier modes example sends describes.
Embodiment one
Under up two carrier modes, strengthen dedicated channel E-DCH for two up-link carriers (for example up-link carrier 1 and up-link carrier 2) of UE dispose respectively, being respectively each E-DCH at down link increases by one group of physical channel: E-DCH absolute grant channel E-AGCH, E-DCH relative authorization channel E-RGCH and E-DCH hybrid automatic repeat request indication channel E-HICH.
Need to prove that in order to save downlink code resource, E-RGCH and E-HICH can share a code channel (spreading code SF=128), do not have chnnel coding, and a plurality of user shares a code channel.Wherein, each UE is the quadrature signature sequence number that distributes the quadrature signature sequence number of a use of E-RGCH channel and distribute a use of E-HICH channel from 40 available quadrature signature sequences number.Like this, a code channel just can be admitted 20 maximum user equipment (UE)s, and each UE respectively has E-RGCH channel and E-HICH channel of a special use on the wall scroll code channel of SF=128 down link.
In the present embodiment, the identical channel code of E-HICH configuration for each E-DCH, namely adopt high-level signaling from SF=128 channel code (0,1,2 ,～, 127), to select same channel code (Channelisation Code) configuration to the E-HICH channel of each E-DCH of UE, for example select Channelisation Code=3 (C
Ch, 128,3) dispose respectively to the E-HICH channel of up-link carrier 1 and the E-HICH channel of up-link carrier 2; In order to distinguish this 4 channels, namely select number configuration of 4 different signature sequences to give this 4 channels 40 quadrature signature sequences from a code channel number to 2 E-RGCH channels of up two carrier waves signature sequence (Signature Sequence) different with 2 E-HICH channel allocation.
2 E-RGCH channels and 2 the E-HICH channels of up two carrier waves after the configuration are sent at a descending carrier, that is, use a descending carrier to send 2 E-HICH channels and 2 E-RGCH channels of two up-link carriers.For example 2 E-RGCH channels and 2 E-HICH channels of up two carrier waves all can be sent by the descending carrier of up-link carrier 1, perhaps all sent by the descending carrier of up-link carrier 2, UE monitors 2 E-HICH and 2 E-RGCH totally 4 channels at descending carrier, distinguishes 2 up-link carriers according to the difference of the signature sequence of configuration number.
Embodiment two
Present embodiment two is with present embodiment one allocation plan difference:
In the present embodiment two, give the different channel code of E-HICH configuration of up-link carrier 1 and up-link carrier 2, namely adopt high-level signaling from SF=128 channel code (0,1,2 ,～, 127), to select different channel codes to dispose E-HICH channel to each up-link carrier of UE, for example select Channelisation Code=5 (C
Ch, 128,5) dispose the E-HICH channel to up-link carrier 1, select another and configuration to the different channel code of the E-HICH channel of up-link carrier 1, for example Channelisation Code=10 (C
Ch, 128,10) dispose the E-HICH channel to up-link carrier 2, in order to distinguish this two up-link carriers.The signature sequence that configuration is used to the E-HICH on the up-link carrier 1 and E-RGCH number is to select 40 quadrature signature sequences number from up-link carrier 1 code channel, select 40 quadrature signature sequences of the signature sequence that configuration is used to the E-HICH on the carrier wave 2 and E-RGCH number from up-link carrier 2 code channels number, and, between the E-HICH of these two up-link carriers or the signature sequence that disposes between the E-RGCH number can be the same or different, but configuration number is different to the E-HICH of same up-link carrier and the signature sequence between the E-RGCH.
Need to prove, in embodiment one and the example two, on the E-RGCH/E-HICH channel on the carrier wave, can use simultaneously 40 quadrature signature sequences number, because the spreading code SF=128 of E-HICH/E-RGCH channel, namely an E-HICH/E-RGCH channel can be configured to use at most 128 different channel codes, even therefore the E-HICH/E-RGCH channel of 2 above carrier waves all is configured on the descending carrier, resource is also enough used.
Embodiment three
Under up two carrier modes, two up-link carriers (for example up-link carrier 1 and up-link carrier 2) difference configuring E-DCH channel for UE, the corresponding E-AGCH1 of the absolute grant channel E-AGCH of the enhancing dedicated channel E-DCH of up-link carrier 1, the corresponding E-AGCH2 of the absolute grant channel E-AGCH of the enhancing dedicated channel E-DCH of up-link carrier 2.
In the present embodiment, to E-AGCH1 and the identical channel code of E-AGCH2 configuration, that is, adopt the high-level signaling same channel code of selection (Channelisation Code) Channelisation Code=45 (C for example from SF=256 channel code (0,1,2 ,～, 255)
Ch, 256,45), dispose respectively E-AGCH1 channel and E-AGCH2 channel to UE, namely up-link carrier 1 and up-link carrier 2 use same E-AGCH channel; Corresponding different up-link carriers are by distributing different E-RNTI to distinguish each up-link carrier to UE, and avoid possible collision with time-multiplexed method.Therefore the control channel (using an E-AGCH channel, different E-RNTI) after will disposing sends at a descending carrier, can distinguish corresponding two up-link carriers.Referring to Fig. 2, as follows to the cataloged procedure of E-AGCH 1 and E-AGCH 2:
The absolute grant that the E-AGCH 1 of corresponding up-link carrier 1 sends comprises the content of following two aspects:
1, absolute grant value: xagv, 1, xagv, 2 ..., xagv, 5.Its scope is 0～31, the power ratio of the E-DPDCH/DPCCH of the maximum that indication UE permission is used.
2, absolute grant scope: xags, 1.The scope of application that it is used for illustrating absolute grant indicates whether that the activation/deactivation of HARQ process affects one or whole processes.
The absolute grant value xagv of E-AGCH 1,1, xagv, 2 ..., xagv, 5 and absolute grant scope xags, 1 is together multiplexing, obtained sequence a: xag, 1, xag, 2 ..., xag, 6, wherein:
xag，k＝xagv，k k＝1，2，...，5
xag，k＝xags，7-k k＝6
By sequence xag, 1, xag, 2 ..., xag, 6, we can obtain the CRC sequence of 16 bits (bits): c1, c2 ..., c16.E-RNTI is the E-DCH Radio Network Temporary Identifier, and corresponding one group of E-RNTI 1 with E-AGCH1 can use xid, 1, xid, and 2 ..., xid, 16 represent.At this moment, just can obtain sequence: y1, y2 ..., y22, wherein:
yi＝xag，i i＝1，2，...，6
yi＝(ci-6+xid，i-6)mod2 i＝7，...，22
By sequence: y1, y2 ..., y22 utilizes 1/3 convolution code, can obtain sequence: z1, z2 ..., z90.
According to sequence z1, z2 ..., z90 through punching, just can obtain sequence r1, r2 ..., r60.For example: can pass through at following content: z1, z2, z5, z6, z7, z11, z12, z14, z15, z17, z23, z24, z31, z37, z44, z47, z61, z63, z64, z71, z72, z75, z77, z80, z83, z84, z85, z87, z88, the mode of z90 punching obtains sequence r1, r2 ..., r60.
By the mapping process of E-AGCH1 physical channel, can be mapped to corresponding up-link carrier.
The E-AGCH2 of corresponding up-link carrier 2, its cataloged procedure is same as E-AGCH1, just uses other one group of E-RNTI2:yid, 1, yid, 2 ..., yid, 16, CRC added cover.Like this, UE is according to two groups of different E-RNTI, and which up-link carrier is the content that just can know transmission be corresponding to.
Present embodiment three can use an E-AGCH channel of down link to support the scheduling of two up-link carriers, and the code resource of having saved down link has reduced the channel quantity that UE need to monitor.
Embodiment four
Present embodiment four is with present embodiment three allocation plan differences:
In present embodiment four, to E-AGCH1 and the different channel code of E-AGCH2 configuration, that is, adopt high-level signaling selection a channel code, for example Channelisation Code=35 (C from SF=256 channel code (0,1,2 ,～, 255)
Ch, 256,35) dispose the E-AGCH1 channel to up-link carrier 1, select another and configuration to the different channel code of the E-HICH channel of up-link carrier 1, for example Channelisation Code=88 (C
Ch, 256,88) dispose the E-AGCH2 channel to up-link carrier 2, in order to distinguish this two up-link carriers; Up-link carrier 1 to UE is distributed to identical E-RNTI with up-link carrier 2.Like this, two up-link carriers use two E-AGCH channels to distinguish different up-link carriers, even use same E-RNTI also can send at a descending carrier.
