The sending method of the enhancing dedicated channel absolute grant channel information that the embodiment of the present invention provides and base station, by providing multithread absolute grant value mapping table, in multithread absolute grant value mapping table, have compressed the number of bits of sequence number corresponding to absolute grant value, and then have compressed absolute grant channel information, be conducive to realizing in a downstream data flow, transmit absolute grant channel information corresponding to two upstreams, can transmission quality being improved when keeping lower transmitting power, can transmitting power be reduced when keeping certain transmission quality; And, in multithread absolute grant value mapping table, decibel quantized interval between adjacent two absolute grant value reduces along with the increase of the power bias value of correspondence, make to comprise the larger power bias value of more numerical value in multithread absolute grant value mapping table, the power bias value larger due to numerical value corresponds to larger message transmission rate, and the development of present data transmission forward high speed, therefore this multithread absolute grant value mapping table can not have much impact to the power bias scheduling of base station.

Refer to Fig. 2, be the second embodiment flow chart of the sending method of enhancing dedicated channel absolute grant channel information provided by the invention, the method comprises:

At S200, the absolute grant value of two upstreams is selected from multithread absolute grant value mapping table, absolute grant value in described multithread absolute grant value mapping table chooses from the absolute grant value of various power bias value correspondence under various code channel combination, in described multithread absolute grant value mapping table, decibel quantized interval between adjacent two absolute grant value reduces along with the increase of the power bias value of correspondence, the number of bits of the multithread sequence number that described absolute grant value is corresponding in described multithread absolute grant value mapping table be greater than 1 and be less than 5 the combination of integer code channel.In multithread absolute grant value mapping table, comprise the corresponding relation of absolute grant value and multithread sequence number.Such as, when the number of bits of multithread sequence number is 4 bit, multithread absolute grant value mapping table can as shown in table 2 or 3.

For example, supposing that the number of bits of multithread sequence number is 4, be multithread sequence number corresponding to absolute grant value that the first upstream is selected is x in step S200 _{agv, 1}, x _{agv, 2}..., x _{agv, n}, be multithread sequence number corresponding to absolute grant value that the second upstream is selected be y _{agv, 1}, y _{agv, 2}..., y _{agv, n}, their scope is 0-15, and is respectively used to the maximum power ratio of Traffic Channel and the pilot tone indicating the permission of UE corresponding on the first upstream and the second upstream to use.

At S201, by multithread sequence number x corresponding for the absolute grant value of the first upstream _{agv, 1}, x _{agv, 2}..., x _{agv, n}, the first upstream absolute grant scope x _{ags, 1}, the second upstream multithread sequence number y corresponding to absolute grant value _{agv, 1}, y _{agv, 2}..., y _{agv, n}and the second absolute grant scope y of upstream _{ags, 1}intertexture is an authorization message bit sequence x _{ag, 1}, x _{ag, 2}..., x _{ag, 2n+2}, n is the number of bits of described multithread sequence number.Such as:

x _ag,k＝x _agv,kk＝1,2,……,n

x _ag,k＝x _ags,n+2-kk＝n+1

x _ag,k＝y _agv,k-n-1k＝n+2,n+3,……,2n+1

x _ag,k＝y _ags,2n+3-kk＝2n+2

For example, if the number of bits of multithread sequence number is 4, step S201 is specially: by the multithread sequence number x of the first upstream _{agv, 1}, x _{agv, 2}..., x _{agv, 4}, absolute grant scope x _{ags, 1}and the second multithread sequence number y of upstream _{agv, 1}, y _{agv, 2}..., y _{agv, 4}, absolute grant scope y _{ags, 1}weave in successively, obtains an authorization message bit sequence x _{ag, 1}, x _{ag, 2}..., x _{ag, 10}, wherein:

x _ag,k＝x _agv,kk＝1,2,……,4

x _ag,k＝x _ags,6-kk＝5

x _ag,k＝y _agv,k-5k＝6,7,……,9

x _ag,k＝y _ags,11-kk＝10

At S202, cyclic redundancy error detection interpolation, chnnel coding and rate-matched are carried out to described authorization message bit sequence, generate and strengthen dedicated channel absolute grant channel information.

For example, if the number of bits of multithread sequence number is 4, in step S202, CRC (CyclicRedundancyCheck, cyclic redundancy error detection) can be carried out to authorization message bit sequence and add: by sequence x _{ag, 1}, x _{ag, 2}..., x _{ag, 10}obtain the CRC sequence c of a 16bits ₁, c ₂..., c ₁₆.E-AGCH is common signal channel, therefore for distinguishing different user, needs to distribute a mark to user, in order to the unique subscriber within the scope of distinguishing cell, namely E-RNTI (E-DCHRadioNetworkTemporaryIdentity, E-DCH Radio Network Temporary Identifier), can use x _{id, 1}, x _{id, 2}..., x _{id, 16}represent.CRC sequence and E-RNTI mould 2 are added, and then by two sequence compounds, obtains sequences y ₁, y ₂..., y ₂₆, wherein:

y _i＝x _ag,ii＝1,2,……,10

y _i＝(c _i-10+x _id,i-10)mod2i＝11,……,26

Then chnnel coding is carried out, by sequences y to the sequence after above-mentioned process ₁, y ₂..., y ₂₆by 1/3 convolution code, sequence z can be obtained ₁, z ₂..., z ₁₀₂.

Continue to carry out rate-matched, by sequence z to the sequence after chnnel coding ₁, z ₂..., z ₁₀₂punching, obtains sequence r ₁, r ₂..., r ₆₀.

At S203, send described enhancing dedicated channel absolute grant channel information by a downstream data flow.

Refer to Fig. 5, it is the second example structure schematic diagram of base station provided by the invention, comprise absolute grant value and select module 410, absolute grant channel information generating module 420 and absolute grant channel information sending module 430, wherein absolute grant channel information generating module 420 comprises authorization message bit sequence generation module 510 and coding module 520.

Authorization message bit sequence generation module 510, for by multithread sequence number x corresponding for the absolute grant value of the first upstream _{agv, 1}, x _{agv, 2}..., x _{agv, n}, the first upstream absolute grant scope x _{ags, 1}, the second upstream multithread sequence number y corresponding to absolute grant value _{agv, 1}, y _{agv, 2}..., y _{agv, n}and the second absolute grant scope y of upstream _{ags, 1}intertexture is an authorization message bit sequence x _{ag, 1}, x _{ag, 2}..., x _{ag, 2n+2}, n is the number of bits of described multithread sequence number.

Coding module 520, for carrying out cyclic redundancy error detection interpolation, chnnel coding and rate-matched to described authorization message bit sequence, generating and strengthening dedicated channel absolute grant channel information.

In some cases, the code channel combination used when can also limit upstream transmission.Such as, the transmission rate combined due to different code channel is different, therefore in order to improve transmission rate, can be limited in by upstream transmission on a certain code channel combination (such as 2*SF2+2*SF4) when arranging multithread absolute grant value mapping table.Such as, preferably, when the code channel combination for transmitting described two upstreams is restricted to 4 code channel, the absolute grant value in described multithread absolute grant value mapping table chooses from the absolute grant value of various power bias value correspondence under 4 code channels.For example, for kind of the power bias value of 30 shown in table 1, absolute grant value corresponding under 4 code channels is supplemented complete rear as shown in table 4.Then with reference to the set-up mode of table 2 and table 3,16 can be selected as the absolute grant value in multithread absolute grant value mapping table from kind of the absolute grant value of 30 shown in table 4.Such as, decibel absolute grant value that quantized value 0dB, 6dB, 11dB, 15dB, 18dB, 20dB, 22dB, 23dB, 24dB, 25dB, 26dB, 27dB, 28dB, 29dB are corresponding can be chosen from table 4, generate the multithread absolute grant value mapping table under 4 code channels, as shown in table 5.Therefore, in step S200 (or absolute grant value selects module 410), the absolute grant value of two upstreams can be selected from table 5, uplink can be limited in this 4 code channel combinations of 2*SF2+2*SF4 like this, thus reach the highest transmission rate.
