Fig. 1 be downlink control information sending method embodiment one of the present invention flow chart, the present embodiment provide method can be performed by Downlink Control Information dispensing device, the device is integrated in base station, the present embodiment offer method Bao include Yi Xia Walk it is rapid.

Walk rapid 101, base station are generated under the first UE the first downlink control message and the second of the 2nd UE Downlink Control Information is included in row control message, downlink control message.

In asymmetric up-downgoing carrier system, UE sends a sub-frame of uplink 4ms to base station, and base station sends a descending sub frame to UE and only uses 2ms, therefore, in down control channel, base station can just control a sub-frame of uplink with 2ms descending sub frame.

In the present embodiment, base station sends downlink control message in units of subframe or time slot, when base station need to two access network UE send Downlink Control Information when, respectively generate the first UE the first downlink control message, and the 2nd UE the second downlink control message.

Base station sends corresponding downlink control message on down control channel to UE, wherein, down control channel is f-dpch（) or Dedicated Physical Control Channel F-DPCH（DPCCH),.Base station sends downlink control message for the power control information for the 4ms sub-frame of uplink for controlling UE to be sent in subsequent time successively in F-DPCH channels, DPCCH channels.

Walk rapid 102, base station use identical channel code, and the first downlink control message is sent to the first UE in first paragraph duration, and the second downlink control message is sent to the 2nd UE in second segment duration.

In the present embodiment, when base station sends downlink control message in units of subframe, first paragraph duration and second segment duration are all 2ms, and base station is in 4ms, the first descending sub frame is sent to the first UE in preceding 2ms, the second descending sub frame is sent to the 2nd UE in rear 2ms.When base station sends downlink control message in units of time slot, base station is in different time slots to respectively to UE transmission downlink control messages, in the first time slot the first downlink control message is sent to the first UE, in the second time slot the second downlink control message is sent to the 2nd UE, wherein, base station sends downlink control message to the first UE and the 2nd UE and uses identical channel code.It should be noted that it is different to send the channel code that downlink control message uses in different down channel, still, it is identical on same down channel to two UE to send the channel code that downlink control messages use.

In the present embodiment, base station to two UE when sending downlink control message, in 4ms duration, using identical channel code, in first paragraph duration the first downlink control message is sent to the first UE, the second downlink control message is sent to the 2nd UE in second segment duration, therefore, downlink control message can be sent to two UE in 4ms.And in the prior art, base station can only send Downlink Control Information to a UE in 4ms, in this implementation, identical channel code is used by configuring two UE, base station enable in 4ms duration, downlink control message is sent to two UE, so as to improve the utilization rate of downlink resource.Specifically, when base station sends downlink control message in units of subframe to UE, in 4ms, the first descending sub frame is sent to the first UE in preceding 2m, is sent in rear 2ms to the 2nd UE under second Row subframe.When base station sends downlink control message in units of time slot to UE, in 4ms durations, 6 downlink control messages can be sent, in the first time slot the first downlink control message is sent to the first UE, in the second time slot the second downlink control message is sent to the 2nd UE, in 4ms, across sending corresponding control message to the first UE and the 2nd UE.

Jin mono- Walk's, in another embodiment of the present invention, on the basis of above-mentioned embodiment illustrated in fig. 1, in a kind of implementation of the present invention; before Walk rapid 102, i.e., base station uses identical channel code, and first downlink control message is sent to the first UE in first paragraph duration, before second segment duration sends the second downlink control message to the 2nd UE, it can include rapid with lower Walk to wrap.

Base station receives radio network controller（RNC) the down channel configuration information sent, and down channel configuration information is sent to the first UE and the 2nd UE, so that the first UE and the 2nd UE receives the first downlink control message and the second downlink control message according to down channel configuration information, wherein, down channel configuration information includes：Identical channel code used in first UE and the 2nd UE, and the first UE and the 2nd UE down channel and Primary Common Control Physical Channel timing off-set value so that the first UE and the 2nd UE subframe or time slot keep alignment.

Specifically, down channel configuration information includes：The identical channel code that first UE and the 2nd UE are used in same down control channel, subframe alignment mode is specially：Descending sub frame alignment or difference 2ms integral multiple that first UE and the 2nd UE is sent, first UE and the 2nd UE descending time slot alignment or difference integral multiple time slot, wherein, down control channel is F-DPCH channels or DPCCH channels, and above-mentioned each channel is all special down channel.

In UE access networks, UE downstream arrangements information is sent to UE by RNC, wherein, first

UE and the 2nd UE can be accessed simultaneously, accessed when can also be different, after two UE are accessed simultaneously, the channel code used in same down channel that RNC configures two UE is identical, and two UE of configuration subframe or time slot alignment, and send configuration information to base station, to cause base station to be transmitted when sending downlink control message to UE according to configuration information, simultaneously, configuration information is sent respectively to the first UE and the 2nd UE by base station after down channel configuration information is received.When being accessed when two UE are different, RNC is in the UE configurating downlink channel configuration informations accessed for after, configuration information according to the UE of preceding access carries out relevant configuration, the UE accessed after configuring channel code is identical with the channel code of the UE in preceding access, and the UE subframe that is accessed after configuring and the subframe alignment of the UE in preceding access either differ 2ms integral multiple or configuration after the UE time slot that accesses and preceding access UE time slot alignment or differ integral multiple time slot. Base station to UE when sending downlink control message, according to the configuration information of down channel, using identical channel code, the first downlink control message is sent to the first UE in first paragraph duration, the second downlink control message is sent to the 2nd UE in second segment duration, is specially：After base station is spread to the first downlink control message and the second downlink control message using identical channel code, the first downlink control message is sent to the first UE in first paragraph duration, the second downlink control message is sent to the 2nd UE in second segment duration.

In addition, downstream arrangements information can also include：Configured information is received, for indicating that the first UE receives the downlink control message that numbering is odd number, the 2nd UE receives the downlink control message that numbering is even number.When base station, which is used, sends downlink control message in units of subframe, base station can indicate that the subframe downlink control message that UE is received is odd number or even number when to UE configurating downlink channels, or base station includes odd number frame number or even number frame number in the descending sub frame sent to UE, UE is when receiving, the subframe number indicated according to base station or the position according to where subframe determine that the subframe received is odd number or even subframe, and according to configured information, receive itself and number corresponding descending sub frame.Due to, base station uses identical channel code when sending descending sub frame to the first UE and the 2nd UE, therefore, and the first UE and the 2nd UE can receive all descending sub frames of base station transmission, UE is after descending sub frame is received, confirm whether the descending sub frame is to be sent to the descending sub frame of oneself according to numbering, for the first UE, only receive odd numbered sub-frames, ignore even subframe, for the 2nd UE, even subframe is only received, ignores odd numbered sub-frames.Same, when base station sends downlink control message in units of time slot, UE determines that the numbering of the downlink control message received is odd number or even number according to the time slot position for receiving configured information and the downlink control message received, and then whether to one's name to determine downlink control message, or the numbering that UE is included according to receiving in configured information and the downlink control message received, it is determined that to one's name whether the downlink control message received.

Feasible it is implementation another, base station is identified in the first downlink control message sent to the first UE comprising the first UE, identified in the second downlink control message sent to the 2nd UE comprising the 2nd UE, to cause the first UE to receive the first downlink control message according to the first UE marks, the 2nd UE receives the second downlink control message according to the 2nd UE marks.Specifically, UE is after downlink control message is received, parsing obtains the UE marks in the downlink control message, if the mark for including the first UE in the downlink control message that the first UE parsings are obtained, then the first UE judges the downlink control message to one's name, and the transmission of subsequent time sub-frame of uplink is controlled according to Downlink Control Information, if the mark for including the 2nd UE in the downlink control message that the first UE parsings are obtained, then the first UE judges that the downlink control message is not belonging to oneself, abandons the downlink control message.Similarly, the 2nd UE is after downlink control message is received, According to the UE marks carried in the downlink control message, whether to one's name the downlink control message is judged, corresponding processing is performed if belonging to, the downlink control message is abandoned if being not belonging to.Wherein UE mark, can be the signing messages of user or UE wireless network identification.

It will be illustrated below by specific down channel, for F-DPCH and DPCCH channels, when UE is accessed, RNC configures two UE and uses identical channel code, and two UE of configuration sub-frame frame or time slot alignment, two UE of configuration subframe alignment refers to the 0th 2ms subframe alignment for configuring two UE or the integral multiple for differing 2ms, can be by the frame shifting amount r of the DPCH for configuring two UE_OTe^, fractional dedicated physical channel frame shifting amount ^ it is identical or difference 2ms integral multiple, wherein,_e^ refers on the basis of Primary Common Control Physical Channel P-CCPCH, time delay of the DPCCH channels relative to P-CCPCH is timing slip, in same cell, the sequential of down channel is all the τ of all UE configurations in the cell on the basis of P-CCPCH_ΰρσ^, ^-different, in the present embodiment, by the τ for configuring two UE_{ΰ α}^, ^ are identical or differ 2ms integral multiple so that two UE the 0th 2ms subframe alignment or the integral multiple for differing 2ms.Two UE of configuration time slot alignment refers to two UE of configuration descending time slot alignment or difference integral multiple time slot, and due to equivalent to three time slots of duration of a subframe, therefore, configuration time slot alignment can also be realized by configuring subframe alignment.UE configuration informations are sent to base station and UE by RNC, two UE of configuration subframe alignment is in order that obtaining in 4ms durations, after preceding 2ms has sent the first descending sub frame to the first UE, without interval time, in rear 2ms the second descending sub frame is sent to the 2nd UE, or base station is after the first time slot has sent the first downlink control message to the first UE, without interval time, the second downlink control message is sent to the 2nd UE in the second time slot.

When base station sends downlink control message in F-DPCH channels or DPCCH to UE, second downlink control message of the first downlink control message and the 2nd UE to being sent to the first UE is spread using identical channel code, in 4ms, preceding two 2ms sends the first descending sub frame to the first UE, in rear 2ms the second descending sub frame is sent to the 2nd UE, or send the second downlink control message to the 2nd UE in the second time slot to the first UE the first downlink control messages of transmission in the first time slot.If if lower empty control message is numbered, by taking subframe as an example, the numbering of first subframe is 0 to count, angle from base station, as a whole, base station sends the first subframe in even frame to the first UE, and the second subframe is sent to the 2nd UE in odd numbered sub-frames.Individually from the perspective of UE, when the even subframe alignment of the first UE even subframe and the 2nd UE, in other words, that is the odd numbered sub-frames of the first UE and the 2nd UE are also alignment, then base station sends the first descending sub frame in even subframe to the first UE, and the is sent to the 2nd UE in odd numbered sub-frames Two descending sub frames；When the odd numbered sub-frames alignment of first UE even subframe and the 2nd UE, base station only sends the first subframe in even subframe to the first UE, and only sends the second subframe to the 2nd UE in even subframe;Base station only sends the first subframe in odd numbered sub-frames to the first UE, and only sends the second subframe to the 2nd UE in odd numbered sub-frames.For the first UE or the 2nd UE, a descending sub frame is sent out in base station equivalent at interval of 2ms, and the 4ms sub-frame of uplink that UE is sent in subsequent time is controlled by a 2ms descending sub frame.

RNC can also include configured information in configuration information, indicate that the first UE receives the subframe of even-numbered, indicate that the 2nd UE receives the subframe of odd-numbered.Or, base station carries UE marks in descending sub frame so that UE receives itself corresponding subframe according to mark.Similarly, when base station sends downlink control message in units of time slot, the above method is also suitable, and is just repeated no more here.

It should be noted that the method that the present embodiment is provided is equally applicable to E-HICH channels, E-RGCH and E-AGCH channels.For E-HICH channels and E-RGCH channels, in the prior art, E-RGCH and E-HICH use identical channel code, are distinguished with different signatures.E-AGCH is shared channel, different user can use identical channel code, and UE information of the UE in downlink signaling determines whether to be sent to this user.Therefore, in the present embodiment, when UE is accessed, RNC configures two UE and uses identical channel code in same down channel, and two UE of configuration subframe or time slot are alignd, the mode of subframe or time slot alignment is identical with F-DPCH channels or DPCCH channels, just repeats no more here.As shown in Fig. 2 Fig. 2 is the frame timing schematic diagram of E-HICH channels, tE-HICH is time delay of the E-HICH frames relative to P-CCPCH subframes.In addition, the timing slip being had an agreement between E-HICH subframes and E-DCH subframes.In UE-secondary access procedure, it is different that RNC, which is allocated to the channel code that each down channels of UE use, specifically, the channel code of E-HICH channels is different from the channel code of F-DPCH channels and DPCCH, but E-HICH channels are identical with the channel code of E-RGCH channels, and subframe timing alignment is also identical, therefore, compared with F-DPCH channels with DPCCH channel, for E-HICH channels and E-RGCH channels, in addition it is also necessary to configure signature sequence signature to distinguish different channels.

RNC sends configuration information to base station and UE, for E-HICH channels, as shown in Figure 3, Fig. 3 is the schematic diagram that E-HICH frames are sent to two UE, base station is received after the up E-DCH subframes of 4ms that the first UE and the 2nd UE is sent at the same time, in 4ms downstream cycles, uses identical channel code, 2ms the first descending sub frame is sent to the first UE in preceding 2ms, in the case where rear 2ms sends the second of 2ms to the 2nd UE to subframe.Continuous during the 4ms sub-frame of uplink that UE is sent, therefore, as a whole, base station sends the first descending sub frame in even subframe to the first UE, in odd numbered sub-frames to second UE sends the second descending sub frame.Similarly, for E-HICH channels, base station sends the first descending sub frame in even subframe to the first UE, and the second descending sub frame is sent to the 2nd UE in odd numbered sub-frames.First UE and the 2nd UE receive corresponding descending sub frame as indicated, can refer to the description to F-DPCH channels, repeat no more here.

For E-AGCH channels, difference with other down channels is, it is not necessary to two UE frame timing alignment is configured, in same cell, all UE E-AGCH descending sub frames are all 5120 chips relative to PCCPCH delays, therefore all UE the 0th work song frame is all alignment.Therefore it may only be necessary to which the channel code for configuring two UE is identical, specific implementation can refer to the description of other channels, repeat no more here.

Because Downlink Control Information can be sent in units of subframe, then base station sends the first downlink control message in first paragraph duration to the first UE, in second segment duration the second downlink control message is sent to the 2nd UE, specially, base station sends the first downlink control message in the first descending sub frame to the first UE, and the second downlink control message is sent to the 2nd UE in the second descending sub frame.Base station is sending the first downlink control message to the first UE, after the second downlink control message is sent to the 2nd UE, the first sub-frame of uplink that the first UE is sent according to the first Downlink Control Information is received always according to the corresponding reception time, the second sub-frame of uplink that the 2nd UE is sent according to the second Downlink Control Information is received.

In 2ms Τ patterns, i.e., in the UMTS access networks of traditional 5M bandwidth, the timing entry-into-force time for the descending E-AGCH subframes that UE is received is as follows：Assuming that UE receives E-AGCH subframes in the jth subframe of i-th of system-frame, then the E-AGCH subframes come into force on t-th of E-DCH sub-frame of uplink of the i-th+s system-frames.Wherein, s and t are calculated in the following manner：

Wherein, i represents the numbering of system-frame, and i span is 0 4095 integer, and j represents the numbering of subframe, and j span is 04 integer, and L " represents downward rounding operation, and "] represents the computing that rounds up,_pe^ represents the frame shifting amount of DPCH, for E-HICH subframes, assuming that UE receives E-HICH subframes in j-th of subframe of i-th of system-frame, then the entry-into-force time of the E-HICH subframes is to be come into force on t-th of E-D sub-frame of uplink of the i-th-s system-frames, here ^¹-^³」, , = ( +²)_m0d⁵ _moD represents complementation.

It is above-mentioned for E-AGCH descending sub frames and the calculation of the entry-into-force time of E-HICH descending sub frames, Suitable for the UMTS system that upstream bandwidth is 5M, the transmission time of the next up E-DCH subframes of 5M bandwidth is 2ms, when upstream bandwidth is the narrow bandwidth system less than 5M, the time for sending a up E-DCH subframe is elongated, when with a width of 2.5M, up E-DCH subframe durations are changed into 4ms, and the time of descending sub frame is still 2ms, this is the sub-frame of uplink that 4ms is controlled with a 2ms descending sub frame, rather than original 2ms sub-frame of uplink, therefore, the entry-into-force time of descending sub frame is also changed.In order to not change the entry-into-force time of original Downlink Control Information, the process of conversion in the middle of one is added, detailed process is as follows：

When down control channel is E-AGCH channels or E-HICH channels, also include in down control channel configuration information：Ya Shrink factors N, first UE the first index value and the 2nd UE the second index value, so that the base station calculates the first entry-into-force time of the first Downlink Control Information and the second entry-into-force time of the second Downlink Control Information according to Ya Shrink factors N and index value, and the first sub-frame of uplink that the first UE is sent according to the first downlink control message is received in corresponding first entry-into-force time, the second sub-frame of uplink that the 2nd UE is sent according to the second downlink control message is received in corresponding second entry-into-force time.Simultaneously, base station will press the Shrink factors and index value to be sent to the first UE and the 2nd UE, so that the first UE and the 2nd UE are after corresponding downlink control message is received, the corresponding entry-into-force time is calculated according to the pressure Shrink factors and index value, the entry-into-force time then, control sub-frame of uplink transmission.

Wherein Ya Shrink factors N=sub-frame of uplink length/5M bandwidth UMTS sub-frame of uplink length, or the bandwidth of N=5M bandwidth/sub-frame of uplink, 5M bandwidth UMTS sub-frame of uplink length is 2ms, in asymmetric UMTS system, when sub-frame of uplink length is 4ms, N=4/2=2, when sub-frame of uplink length is 8ms, N=8/2=4.It is corresponding, when sub-frame of uplink length is 4ms, , Ya Shrink factors N=5/2.5=2 when sub-frame of uplink transmission bandwidth is 2.5M, when sub-frame of uplink length is 8ms, the transmission bandwidth of sub-frame of uplink is 1.25M , Ya Shrink factors N=5/1.25=4.Index span is 0 N-1, and index is allocated to base station and UE by RNC, according to the index that is arranged in order for sending descending sub frame.In the present embodiment, the first UE index values are 0, and the 2nd UE index values are 1.

Assuming that base station sends E-AGCH subframes in j-th of subframe of i-th of system-frame to UE, base station calculates intermediate variable i' and j ' according to below equation：

Wherein, N is the pressure Shrink factors, and Index is index value, and TF is System Frame Number conversion factor, and TF is obtained by the high-level signaling configuration of Internet, and TF span is 0 N-1, index span For 0 N-1 integer, i span is 0 4095 integer, and j span is 04 integer, and mod represents complementation, and L " represents downward rounding operation.TF can be determined by RNC and be notified, to base station, UE to be reinformed by base station, can also be determined by base station oneself, it is determined that after TF, TF is informed UE by base station by way of high-level signaling.

Optionally, base station network equipment can also know that bandwidth is less than the System Frame Number and subframe numbers of 5M up-link carrier system, and i' and j ' constantly, can also be determined according to the System Frame Number i and j of the system of descending carrier system.Using N as 2 for example, a total of 4096 of System Frame Number, numbering is followed successively by 0-4095, when N is 2, the System Frame Number 4096 that bandwidth is less than to 5M up-link carrier system is divided into two parts, Part I numbering is 0 2047, Part II numbering is 2,048 4095, if the System Frame Number i' of up-link carrier system is 11 10 when base station sends Downlink Control Information, then the frame number falls in Part I, TF spans are 0, if the System Frame Number j ' of up-link carrier system falls in Part II when base station sends Downlink Control Information, TF values are 1.Therefore, it is that TF is configured to 0 by base station in 0 2047 in System Frame Number, is that TF is configured to 1 by base station in 2,048 4095 in System Frame Number.TF can be determined by RNC and be notified, to base station, UE to be reinformed by base station, can also be determined by base station oneself, it is determined that after TF, TF is informed UE by base station by way of high-level signaling.

Jin mono- Walk's, base station is it is determined that after i' and j ', time offset s and t are determined according to i' and j ' and below equation:

3θ7 *+ 100 - τ_£ /256

30 3θ7 *+ 100 - ^ DPCH ,η I 256 - 1505

30

Wherein,, " be Dedicated Physical Control Channel DPCH channels frame shifting amount, ", expression rounds up computing; L " downward rounding operation is represented, i' spans are 0 4095 integer, and j ' span is 04 integer, it is determined that after s and t, then understand t-th sub-frame of uplink of the entry-into-force time of the Downlink Control Information for the i-th '+s System Frame Numbers, and the entry-into-force time then, receive the sub-frame of uplink that UE is sent.

For E-HICH descending sub frames, intermediate variable i' and j ' calculation formula and above-mentioned E-AGCH subframes it is identical, but time offset s is different with t calculation, and s and t pass through below equation meter

5 = 1 - j + 2 )mod5 Wherein, L " represent downward rounding operation, mod represents complementation, j' span is 04 integer, the downlink control message sent in E-HICH descending sub frames comes into effect in t-th of subframe of the i-th '-s system-frames, and the entry-into-force time then, receive UE send sub-frame of uplink.

The method that the present embodiment is provided, in the case where not changing the computational methods of existing entry-into-force time, can also control the transmission of sub-frame of uplink in up narrow bandwidth UMTS network by descending sub frame.

By above-mentioned to F-DPCH, DPCCH, E-AGCH, E-HICH, the description of E-RGCH channels is understood, alignd by configuring two UE using identical channel code and subframe timing, so that base station is in 4ms downstream cycle, 2ms descending sub frame can be sent respectively to two UE, the effective utilization rates of 2ms that would sit idle for, improve the utilization rate of downlink resource.

AICH channels are also down control channel, but with F-DPCH channels, DPCCH channels,

E-AGCH channels, E-HICH channels, E-RGCH channels are different, and AICH channels belong to shared channel.In one cell, when UE is accessed, all UE can send access lead information using two multi-upstream access channels, and base station to UE when sending descending access configured information, access configured information can be the access request for receiving UE or the access request for refusing UE, descending access configured information, two multi-upstream access channel two uplink sub-carriers of correspondence, AICH channels one downlink sub-carrier of correspondence are all sent using shared AICH channels for all UE.Therefore, two up subcarriers of one descending carrier correspondence, and two multi-upstream access channel timings are based on same down channel, when base station receives the access lead information that two UE are sent by two multi-upstream access channels simultaneously, base station can only be to by AICH channels, a UE sends access configured information thereto, therefore there is the problem of descending instruction conflicts.In asymmetric up-downgoing carrier system, when 2 users access from different sub-carrier simultaneously, it is impossible to while carrying out accurate Access Control to 2 users.In the prior art, for the different Physical Random Access Channels under a carrier wave（Physical Random Access Channel, abbreviation PRACH) corresponding to the timing slips of AICH channels can configure different values, after two UE send access lead information using the different PRACH channels of same subcarrier, base station receives the access lead information that two UE are sent simultaneously, because different PRACH channels are different from the timing slip of AICH channels, therefore, base station sends access configured information respectively in different time slots to two UE, is also not in the problem of access indicates conflict.

Fig. 4 be downlink control information sending method embodiment two of the present invention flow chart, this implementations provide method, for solve it is descending indicate conflict the problem of, as shown in figure 4, the present embodiment offer method, Bao include Yi Xia Walk it is rapid. The second access lead information that the first access lead information and the 2nd UE that Walk rapid 201, base station the first UE of reception are sent by the first subcarrier are sent by the second subcarrier.

First UE sends the first access lead information by the first subcarrier to base station, simultaneously, 2nd UE sends the second access lead information by the second subcarrier to base station, and therefore, base station can receive the first access lead information and the second access lead information simultaneously.

Walk rapid 202, base station generate the first UE the first access configured information and the 2nd UE the second access configured information, wherein, first access configured information is corresponding with the first access lead information, and the second access configured information is corresponding with the second access lead information.

Base station is after the first access lead information of the first UE transmissions is received, generate the corresponding first access configured information of the first access lead information, base station is after the second access lead information of the 2nd UE transmissions is received, the corresponding second access configured information of the second access lead information of generation.

Walk rapid 203, base station use identical channel code, indicate that time slot sends first to the first UE and accesses configured information in the first access, indicate that time slot sends second to the 2nd UE and accesses configured information in the second access, so that the first UE is according to the first access configured information access network, the 2nd UE is according to the second access configured information access network.

Base station is after generation first accesses configured information and the second access configured information, on AICH channels, indicate that time slot sends first to the first UE and accesses configured information in the first access, indicate that time slot sends second to the 2nd UE and accesses configured information in the second access, wherein, send access configured information to two UE and use identical channel code.For the first UE accessed using the first subcarrier, the first access can be sent according to existing access slot to indicate, and can postpone N time slots than the first access slot for the 2nd UE accessed using the second subcarrier, N is more than or equal to 1 and is less than or equal to 14.But the present invention is not limited thereto, as long as ensureing that the first access slot and the second access slot are different.As shown in figure 5, Fig. 5 is that the access slot figure for accessing configured information is sent to two UE, the first UE and the 2nd UE send access lead information to base station simultaneously using different uplink sub-carriers（Pre-amble), base station returns to access configured information after p-a durations to UE, p-a=7680 represent the duration of a length of 7680 chips during p-a in figure, postpone base station after 7680 chips and send the first access instruction message to the first UE in the first time slot, send access to the 2nd UE in the second access slot and indicate message.

Base station is transmitted when sending the access slot of access configured information according to RNC configuration information, simultaneously, configuration information is also broadcast to all UE by base station, during so that different UE is using 2 uplink sub-carrier accesses, the access configured information that base station is sent is received according to the corresponding access slot of each subcarrier. Correspondingly, the first UE receives the first access configured information that base station is sent according to corresponding first access slot of the first subcarrier, and the 2nd UE receives second according to corresponding second access slot of the second subcarrier and accesses configured information.

The method that the present embodiment is provided, base station is received after the access lead information that two UE are sent at the same time, based on different timing slips, access configured information is sent to two UE respectively in different time slots, so as to avoid access from indicating collision problem.

Jin mono- Walk's, in another embodiment of the present invention, on the basis of above-mentioned embodiment illustrated in fig. 2, in a kind of implementation of the present invention; before Walk rapid 203, i.e., base station uses identical channel code, and sending first to the first UE in the first time slot accesses configured information, before the second access indicates that time slot sends the second access configured information to the 2nd UE, it can include rapid with lower Walk to wrap.

Base station receives radio network controller（RNC) capture sent is indicated（AICH) channel configuration information, and AICH channel configuration informations are broadcast into the first UE and the 2nd UE, so that the first UE and the 2nd UE receives first according to AICH channel configuration informations accesses configured information and the second access configured information, wherein, AICH channel configuration informations include：Identical channel code used in first UE and the 2nd UE, and the first access slot are different relative to the timing slip of the second access lead information from the second access slot relative to the timing slip of the first access lead information.

Because the first access slot is different relative to the timing slip of the second access lead information from the second access slot relative to the timing slip of the first access lead information, therefore, it ensure that base station sends access configured information to two UE respectively in different time slots, specifically, after base station indicates that the first access message and the second access indicate message using identical channel code spread spectrum, first being sent to the first UE in the first access slot and accessing configured information, sending second to the 2nd UE in the second access slot accesses configured information.Correspondingly, UE receives itself corresponding access configured information according to respective timing slip.

Fig. 6 is the flow chart of downlink control information sending method embodiment three of the present invention, the method that this implementation is provided, the problem of being also used for solving descending instruction conflict, but it is different with the method that embodiment two is provided, in the present embodiment, access configured information is sent in the 2nd UE for sending access configured information to the first UE accessed by the first subcarrier and being accessed by the second subcarrier and uses different channel codes, so as to avoid access from indicating conflict.As shown in fig. 6, the present embodiment provide method, Bao include Yi Xia Walk it is rapid.

The second access lead information that the first access lead information and the 2nd UE that Walk rapid 301, base station the first UE of reception are sent by the first subcarrier are sent by the second subcarrier.

First UE sends the first access lead information by the first subcarrier to base station, meanwhile, the 2nd UE Second access lead information is sent to base station by the second subcarrier, therefore, base station can receive the first access lead information and the second access lead information simultaneously.

Walk rapid 302, base station generate the first UE the first access configured information and the 2nd UE the second access configured information, wherein, first access configured information is corresponding with the first access lead information, and the second access configured information is corresponding with the second access lead information.

Walk rapid 303, base station use different channel codes, the first access is sent to the first UE to indicate message and access to the 2nd UE transmissions second to indicate message, so that the first UE is according to the first access configured information access network, the 2nd UE is according to the second access configured information access network.

Base station is after generation first accesses configured information and the second access configured information, the first access configured information and the second access configured information are spread respectively using different channel codes, on AICH channels, first, which is sent, to the first UE accesses configured information, second is sent to the 2nd UE and accesses configured information, because two UE use different channel codes, therefore, access being sent to the first UE and the 2nd UE simultaneously and indicating message, conflict is indicated without existing.But, the method provided compared to embodiment two, it is necessary to increase a channel code in the present embodiment.Correspondingly, the first UE receives first according to the channel code for being allocated to the first UE and accesses configured information, and the 2nd UE receives second according to the channel code for being allocated to the 2nd UE and accesses configured information, do not interfere with each other.

The method that the present embodiment is provided, base station is received after the access lead information that two UE are sent at the same time, access configured information is sent to two UE respectively by using different channel codes, so as to avoid access from indicating collision problem.

Jin mono- Walk's, in another embodiment of the present invention, on the basis of above-mentioned embodiment illustrated in fig. 3, in a kind of implementation of the present invention before Walk rapid 303, i.e. base station uses different channel codes, the first access is sent to the first UE to indicate message and access to the 2nd UE transmissions second to indicate message, so that the first UE is according to the first access lead information access network, before 2nd UE is according to the second access lead information access network, it can include rapid with lower Walk to wrap.

Base station receives radio network controller（RNC the capture for each uplink sub-carrier) sent is indicated（AICH) channel configuration information, and AICH channel configuration informations are broadcast into the first UE and the 2nd UE, so that the first UE and the 2nd UE is received before the first access according to AICH channel configuration informations Information and the second access lead information are led, wherein, AICH channel configuration informations include：Different channel code used in first UE and the 2nd UE.

Base station to UE when sending access configured information, according to AICH channel configuration informations, after spreading the first access configured information and the second access configured information using different channel codes, indicate message to the access of the first UE transmissions first and send described second to the 2nd UE to access instruction message.For example, for the first UE accessed using the first subcarrier, base station is spread when sending the first access configured information to the first UE using the first channel code, for the 2nd UE accessed using the second subcarrier, base station is spread when sending the second access configured information to the 2nd UE using second channelization code, wherein, the first channel code is different with second channelization code.

Because base station to the first UE and the 2nd UE when sending descending access configured information, use different channel codes, therefore, access configured information can be sent based on existing slot timing, i.e. two UE access configured information can be with identical relative to the timing slip of access lead information, can also be different.

Fig. 7 be Downlink Control Information method of reseptance example IV of the present invention flow chart, the present embodiment provide method can be performed by Downlink Control Information dispensing device, the device is integrated in UE, the present embodiment offer method Bao include Yi Xia Walk it is rapid.

Walk rapid 401, UE receive the downlink control message for the down control channel that base station is sent, wherein, the numbering comprising UE marks or downlink control message in downlink control message.

In the present embodiment, UE is received before the downlink control message for the down control channel that base station is sent, and also receives the down channel configuration information that RNC is sent, and the down channel configuration information is sent to UE by RNC by base station.Wherein, down channel configuration information includes：The channel code that UE is used in down control channel, and down control channel and Primary Common Control Physical Channel timing slip.Wherein, the timing slip of configurating downlink control channel and Primary Common Control Physical Channel causes the first UE and the 2nd UE subframe alignment or time slot to align.Then UE receives the downlink control message for the down control channel that base station is sent specifically, UE is according to channel code and down control channel and the timing slip of main common control channel, reception downlink control message.

Wherein, down control channel is that the channel code that uses of F-DPCH channels or the different down control channel of DPCCH channels is different, and UE is according to being allocated to the channel code of each down control channel of itself in reception of corresponding time descending sub frame.

Downstream arrangements information also includes：Configured information is received, for indicating that UE receives the corresponding downlink control message of numbering, UE is inclined according to the timing of channel code and down control channel and main common control channel Move, the downlink control message for receiving down control channel is specially：UE is according to the timing slip of channel code, down control channel and Primary Common Control Physical Channel, and receives configured information, receives the downlink control message that numbering is odd number, or receive the downlink control message that numbering is even number.If base station carries numbering in the downlink control message sent to UE, UE is after downlink control message is received, according to the numbering of downlink control message, determine the downlink control message whether to one's name, for example receive in configured information and indicate that UE receives the downlink control message that numbering is 0, then UE will receive the downlink control message that numbering is 0.If the downlink control message of base station does not carry numbering, UE determines to number according to the time location of the downlink control message received, determine the downlink control message whether to one's name again, specifically, UE determines to number according to the subframe position or time slot position of the downlink control message received.For example, in UE in 2ms TTI descending carrier system, the downlink control message is received in the jth subframe of the down physical channel frame of i-th of System Frame Number bearing downlink control message, UE is according to the time location of the downlink control message, determine the downlink control message whether to one's name, if to one's name, UE determines the E-DCH subframe positions for the up-link carrier system that downlink control message correspondence comes into force by the time location.

In the present embodiment, UE marks can also be included in downlink control message, UE is according to channel code and the timing slip of down control channel and Primary Common Control Physical Channel, receiving downlink control message is specially, UE is according to the timing slip of channel code, down control channel and main common control channel, and UE marks, receive downlink control message.Specifically, UE is after downlink control message is received, according to the UE marks included in downlink control message, determine that the UE is identified whether identical with the mark of itself, the downlink control message is determined if identical to one's name, if the UE marks included in downlink control message are different with the mark of itself, UE ignores or abandoned the message.

Walk rapid 402, UE control the transmission of sub-frame of uplink according to the Downlink Control Information included in downlink control message.

UE calculates the entry-into-force time of the downlink control message after the Downlink Control Information that the downlink control message received is included, first.Down control channel is E-AGCH channels, or E-HICH channels, is also included in down channel configuration message：The Ya Shrink factors N and UE index value；UE controls the transmission of sub-frame of uplink according to the Downlink Control Information included in downlink control message, specifically, calculate the entry-into-force time of downlink control message according to the Ya Shrink factors and index value, and the entry-into-force time then, control the transmission of sub-frame of uplink.

When the downlink control message control sub-frame of uplink that UE is sent according to E-AGCH channels is sent, it is assumed that UE receives the downlink control message in j-th of subframe of i-th of system-frame, and UE is according to network side Predefined below equation, determines intermediate variable i' and j '_: Wherein, the N Wei Ya Shrink factors, index is index value, TF is System Frame Number conversion factor, and TF is obtained by high-level signaling configuration, and index and TF span are 0 N- 1 integer, i span is 0 4095 integer, j span is 04 integer, and mod represents complementation, and L " represents downward rounding operation.N=sub-frame of uplink length/5M bandwidth UMTS sub-frame of uplink length, or the bandwidth of N=5M bandwidth/sub-frame of uplink, 5M bandwidth UMTS sub-frame of uplink length is 2ms, in asymmetric UMTS system, when sub-frame of uplink length is 4ms, N=4/2=2, when sub-frame of uplink length is 8ms, N=8/2=4.Index is index value, is allocated to UE and base station by RNC, Index span is 0 N-1, when N is 2, and in the present embodiment, the first UE index values are 0, and the 2nd UE index values are 1.TF is System Frame Number conversion factor, is obtained by the high-level signaling configuration of network side.

UE is it is determined that after intermediate variable i' and j ', time offset s and t are calculated according to below equation:

30 + 100 -

30 3θ7 *+ 100 - τ_£ 256 - 1505
