Specific embodiment

Purpose, technical scheme and advantage to make the embodiment of the present invention are clearer, below in conjunction with the embodiment of the present invention In attached drawing, the technical solution in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is Part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art All other embodiments obtained without making creative work shall fall within the protection scope of the present invention.

Fig. 1 is the flow chart of downlink control information sending method embodiment one of the present invention, and method provided in this embodiment can To be performed by Downlink Control Information sending device, which is integrated in base station, and method provided in this embodiment includes following Step.

Step 101, base station generate the first downlink control message of the first UE and the second downlink control message of the 2nd UE, Downlink Control Information is included in downlink control message.

In asymmetric uplink and downlink carrier system, UE sends a sub-frame of uplink 4ms to base station, and base station is sent to UE One downlink subframe is only with 2ms, and therefore, in down control channel, base station can control one with the downlink subframe of a 2ms A sub-frame of uplink.

In the present embodiment, base station sends downlink control message as unit of subframe or time slot, when base station is needed to two When UE through accessing network sends Downlink Control Information, the first downlink control message and the 2nd UE of the first UE are generated respectively The second downlink control message.

Base station sends corresponding downlink control message on down control channel to UE, wherein, down control channel is portion Divide Dedicated Physical Control Channel（F-DPCH）Or Dedicated Physical Control Channel（DPCCH）,.Believe in F-DPCH channels, DPCCH base station Road sends downlink control message and is used for the power control information of 4ms sub-frame of uplink that UE is controlled to be sent in subsequent time successively.

Step 102, base station are sent the control of the first downlink to the first UE in first segment duration and are disappeared using identical channel code Breath sends the second downlink control message in second segment duration to the 2nd UE.

In the present embodiment, when base station sends downlink control message as unit of subframe, when first segment duration and second segment Length is all 2ms, and base station sends the first downlink subframe in 4ms, in preceding 2ms to the first UE, and second is sent to the 2nd UE in rear 2ms Downlink subframe.When base station sends downlink control message as unit of time slot, base station is in different time slots to respectively to UE transmissions Downlink control message, the first downlink control message is sent in the first time slot to the first UE, and the is sent to the 2nd UE in the second time slot Two downlink control messages, wherein, base station sends downlink control message to the first UE and the 2nd UE and uses identical channel code.It needs It is noted that the channel code that downlink control message use is sent in different down channels is different, still, in same downlink It is identical that two UE the channel code that downlink control messages use is sent on channel.

In the present embodiment, base station to two UE when sending downlink control message, in the duration of 4ms, using identical Channel code, the first downlink control message is sent in first segment duration to the first UE, and the is sent to the 2nd UE in second segment duration Therefore two downlink control messages, downlink control message can be sent in 4ms to two UE.And the base in 4ms in the prior art Downlink Control Information can only be sent to a UE by standing, and in this implementation, identical channel code is used by the way that two UE are configured so that Base station can send downlink control message, so as to improve the utilization rate of downlink resource in the duration of 4ms to two UE.Tool Body, when base station sends downlink control message as unit of subframe to UE, in 4ms, first is sent to the first UE in preceding 2m Downlink subframe sends the second downlink subframe in rear 2ms to the 2nd UE.Disappear when base station sends downlink control as unit of time slot to UE During breath, in 4ms durations, 6 downlink control messages can be sent, sending the control of the first downlink to the first UE in the first time slot disappears Breath, the second time slot to the 2nd UE send the second downlink control message, in 4ms, across to the first UE and the 2nd UE transmission Corresponding control message.

Further, in another embodiment of the present invention, on the basis of above-mentioned embodiment illustrated in fig. 1, in this hair In a kind of bright realization method, before step 102, i.e., base station uses identical channel code, in first segment duration to first UE sends first downlink control message, before second segment duration sends the second downlink control message to the 2nd UE, may be used also To include the following steps.

Base station receives radio network controller（RNC）The down channel configuration information of transmission, and down channel is matched into confidence Breath is sent to the first UE and the 2nd UE, is controlled so that the first UE and the 2nd UE receives the first downlink according to down channel configuration information Message and the second downlink control message, wherein, down channel configuration information includes：It is identical used in first UE and the 2nd UE Down channel and Primary Common Control Physical Channel the timing off-set value of channel code and the first UE and the 2nd UE so that The subframe or time slot of first UE and the 2nd UE keeps alignment.

Specifically, down channel configuration information includes：The phase that first UE and the 2nd UE are used in same down control channel Same channel code, subframe alignment mode are specially：The downlink subframe alignment or differ 2ms's that first UE and the 2nd UE is sent The descending time slot alignment of integral multiple, the first UE and the 2nd UE or difference integral multiple time slot, wherein, down control channel F- DPCH channels or DPCCH channels, above-mentioned each channel are all dedicated down channels.

In UE access network, the downstream arrangements information of UE is sent to UE by RNC, wherein, the first UE and the 2nd UE can be with It accesses, can not also access simultaneously simultaneously, after two UE are accessed simultaneously, RNC two UE's of configuration makes in same down channel Channel code is identical, and the subframe of two UE of configuration or time slot alignment, and sends configuration information to base station, so that Base station is sent when sending downlink control message to UE according to configuration information, meanwhile, base station is matched receiving down channel After confidence breath, configuration information is sent respectively to the first UE and the 2nd UE.When being accessed when two UE differences, RNC is to be followed by During the UE configurating downlink channel configuration informations entered, relevant configuration is carried out according to the configuration information of the UE of preceding access, i.e. configuration is followed by The channel code of the UE entered is identical with the channel code of the UE in preceding access, and the subframe of UE that is accessed after being configured and in preceding access UE subframe alignment either differ 2ms integral multiple or configuration after the time slot of UE that accesses and preceding access UE when Gap is aligned or difference integral multiple time slot.

Base station to UE when sending downlink control message, according to the configuration information of down channel, using identical channelizing Code, the first downlink control message is sent in first segment duration to the first UE, and the second downlink is sent to the 2nd UE in second segment duration Control message, specially：Base station expands the first downlink control message and the second downlink control message using identical channel code After frequency, the first downlink control message is sent to the first UE in first segment duration, is sent under second to the 2nd UE in second segment duration Row control message.

In addition, downstream arrangements information can also include：Instruction information is received, it is odd number to be used to indicate the first UE and receive number Downlink control message, the 2nd UE receive number be even number downlink control message.It is sent as unit of subframe when base station is used During downlink control message, base station can indicate that the subframe downlink control message that UE is received is odd number when to UE configurating downlink channels Or even number or base station include odd number frame number or even number frame number in the downlink subframe sent to UE, UE is when receiving, root Subframe number or the subframe that receives of the location determination according to where subframe according to base station instruction are odd number or even subframe, and according to It indicates information, receives itself and number corresponding downlink subframe.Since base station to the first UE and the 2nd UE when sending downlink subframe Using identical channel code, therefore, the first UE and the 2nd UE can receive all downlink subframes that base station is sent, and UE exists After receiving downlink subframe, confirm whether the downlink subframe is to be sent to the downlink subframe of oneself according to number, for the first UE For, odd numbered sub-frames are only received, ignore even subframe, for the 2nd UE, even subframe is only received, ignores odd numbered sub-frames.Equally , when base station sends downlink control message as unit of time slot, UE is according to the downlink control for receiving instruction information and receiving The time slot position of message processed determines that the number of the downlink control message received is odd number or even number, and then determines downlink control Message whether to one's name or UE is according to receiving the number included in instruction information and the downlink control message that receives, Determine the downlink control message received whether to one's name.

It is another it is feasible be realization method, base station includes the in the first downlink control message sent to the first UE One UE is identified, comprising the 2nd UE marks in the second downlink control message sent to the 2nd UE, so that the first UE is according to the One UE marks receive the first downlink control message, and the 2nd UE is identified according to the 2nd UE and received the second downlink control message.Specifically, For UE after downlink control message is received, parsing obtains the UE marks in the downlink control message, if what the first UE parsings obtained The mark of the first UE is included in downlink control message, then the first UE judges the downlink control message to one's name, and according to downlink The transmission of information control subsequent time sub-frame of uplink is controlled, if including the 2nd UE in the downlink control message that the first UE parsings obtain Mark, then the first UE judge that the downlink control message is not belonging to oneself, abandon the downlink control message.Similarly, the 2nd UE exists After receiving downlink control message, identified also according to the UE carried in the downlink control message, judge that the downlink control message is It is no to one's name, corresponding processing is performed if belonging to, if being not belonging to abandon the downlink control message.The wherein mark of UE, Can be the signing messages of user or the wireless network identification of UE.

It will be illustrated below by specific down channel, for F-DPCH and DPCCH channels, in UE access, RNC matches Two UE are put using identical channel code, and the sub-frame frame of two UE of configuration or time slot are aligned, and the subframe of two UE is configured Alignment refers to be configured the 0th 2ms subframe alignment of two UE or differs the integral multiple of 2ms, can be by the way that the special of two UE is configured With the frame shifting amount τ of physical channel_DPCH,n, fractional dedicated physical channel frame shifting amount τ_F-DPCH,nIdentical or difference 2ms integer Times, wherein, τ_DPCH,nRefer on the basis of Primary Common Control Physical Channel P-CCPCH, DPCCH channels relative to P-CCPCH delay when Between i.e. timing slip, in same cell, the sequential of down channel is all on the basis of P-CCPCH, in the cell All UE configuration τ_DPCH,n、τ_F-DPCH,nDifference, in the present embodiment, by the τ that two UE are configured_DPCH,n、τ_F-DPCH,nIt is identical or Differ the integral multiple of 2ms so that the 0th 2ms subframe alignment of two UE or the integral multiple for differing 2ms.Two UE's of configuration Time slot alignment refers to the descending time slot alignment of two UE of configuration or difference integral multiple time slot, due to the when appearance of a subframe When in three time slots, therefore, configuration time slot alignment can also be realized by the way that subframe alignment is configured.RNC sends out UE configuration informations Base station and UE are given, the subframe alignment of two UE of configuration is in order to enable in 4ms durations, has been sent in preceding 2ms to the first UE After first downlink subframe, without interval time, when rear 2ms sends the second downlink subframe or base station first to the 2nd UE After gap has sent the first downlink control message to the first UE, without interval time, sent under second to the 2nd UE in the second time slot Row control message.

When base station is when F-DPCH channels or DPCCH send downlink control message to UE, to being sent to the first of the first UE The second downlink control message of downlink control message and the 2nd UE are spread using identical channel code, in 4ms, preceding two 2ms The first downlink subframe is sent to the first UE, the second downlink subframe is sent or in the first time slot to first to the 2nd UE in rear 2ms UE sends the first downlink control message, and the second downlink control message is sent to the 2nd UE in the second time slot.If disappear to lower empty control If breath is numbered, by taking subframe as an example, the number of first subframe is 0 to count, the 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 angle of UE From the point of view of degree, when the even subframe alignment of the even subframe and the 2nd UE of the first UE, in other words, i.e., the first UE's and the 2nd UE is strange Number subframes are also alignment, then base station sends the first downlink subframe in even subframe to the first UE, in odd numbered sub-frames to the 2nd UE Send the second downlink subframe；When the odd numbered sub-frames alignment of the even subframe and the 2nd UE of first UE, base station is only in even subframe The first subframe is sent, and only send the second subframe to the 2nd UE in even subframe to the first UE；Base station is only in odd numbered sub-frames to the One UE sends the first subframe, and only sends the second subframe to the 2nd UE in odd numbered sub-frames.For the first UE or the 2nd UE, base Station is equivalent to sends out a downlink subframe at interval of 2ms, the 4ms sent by a 2ms downlink subframes control UE in subsequent time Sub-frame of uplink.RNC can also receive the subframe of even-numbered, instruction in configuration information comprising instruction information, the first UE of instruction 2nd UE receives the subframe of odd-numbered.Alternatively, base station carried in downlink subframe UE mark so that UE according to mark received from The corresponding subframe of body.Similarly, when base station sends downlink control message as unit of time slot, the above method is also suitable, here Just repeat no more.

It should be noted that method provided in this embodiment is equally applicable to E-HICH channels, E-RGCH and E-AGCH Channel.For E-HICH channels and E-RGCH channels, in the prior art, E-RGCH and E-HICH use identical channel code, It is distinguished with different signatures.E-AGCH is shared channel, and identical channel code may be used in different users, and UE is under UE information in row signaling determines whether to be sent to this user.Therefore, in the present embodiment, in UE access, RNC is configured two UE uses identical channel code in same down channel, and the subframe or time slot alignment, subframe or time slot pair of two UE is configured Neat mode is identical with F-DPCH channels or DPCCH channels, just repeats no more here.As shown in Fig. 2, Fig. 2 is E-HICH channels Frame timing schematic diagram, tE-HICH be E-HICH frames relative to P-CCPCH subframes delay time.In addition, E-HICH subframes The timing slip having an agreement between E-DCH subframes.In access procedure of UE, RNC is allocated to what each down channels of UE used Channel code is different, and specifically, the channel code and F-DPCH channels of E-HICH channels and the channel code of DPCCH are not Together, but E-HICH channels are identical with the channel code of E-RGCH channels, and subframe timing alignment be also it is identical, therefore and F- DPCH channels are compared with the channel of DPCCH, for E-HICH channels and E-RGCH channels, it is also necessary to signature sequence be configured Signature distinguishes different channels.

RNC sends configuration information to base station and UE, for E-HICH channels, as shown in figure 3, Fig. 3 is to be sent out to two UE After the schematic diagram of E-HICH frames, base station is sent to receive the 4ms uplink E-DCH subframes that the first UE and the 2nd UE is sent at the same time, In 4ms downstream cycles, using identical channel code, the first downlink subframe of 2ms is sent to the first UE in preceding 2ms, in rear 2ms To subframe under the second of the 2nd UE transmissions 2ms.It is continuous during the 4ms sub-frame of uplink that UE is sent, therefore, as a whole, base station The first downlink subframe is sent to the first UE in even subframe, the second downlink subframe is sent to the 2nd UE in odd numbered sub-frames.Similarly, For E-HICH channels, base station sends the first downlink subframe to the first UE in even subframe, is sent in odd numbered sub-frames to the 2nd UE Second downlink subframe.First UE and the 2nd UE receive corresponding downlink subframe as indicated, can refer to and F-DPCH channels are retouched It states, which is not described herein again.

Difference for E-AGCH channels and other down channels is not need to the frame timing alignment of two UE of configuration, In same cell, the E-AGCH downlink subframes of all UE are all 5120 chips relative to PCCPCH delays, therefore the 0th of all UE Work song frame is all alignment.Therefore it may only be necessary to which the channel code that two UE are configured is identical, specific implementation can refer to other letters The description in road, which is not described herein again.

Since Downlink Control Information can be sent as unit of subframe, then base station sends the in first segment duration to the first UE One downlink control message sends the second downlink control message, specifically, base station is in the first downlink in second segment duration to the 2nd UE Subframe sends the first downlink control message to the first UE, and the second downlink control message is sent to the 2nd UE in the second downlink subframe. 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, also according to Corresponding receiving time receives the first sub-frame of uplink that the first UE is sent according to the first Downlink Control Information, the 2nd UE of reception according to The second sub-frame of uplink that second Downlink Control Information is sent.

In the TTI patterns of 2ms, i.e., in the UMTS access nets of traditional 5M bandwidth, the downlink E-AGCH that UE is received is sub The timing entry-into-force time of frame is as follows：Assuming that UE receives E-AGCH subframes in j-th of 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 number of system-frame, and the value range of i is 0~4095 integer, and j represents the number of subframe, j's Value range is 0~4 integer,Represent downward rounding operation,Expression rounds up operation, τ_DPCH,nRepresent special object The frame shifting amount of channel is managed, for E-HICH subframes, it is assumed that UE receives E- in j-th of subframe of i-th of system-frame HICH subframes, then the entry-into-force time of the E-HICH subframes is to come into force on t-th of E-D sub-frame of uplink of the i-th-s system-frames, this InT=(j+2) mod5, mod represents complementation.

The entry-into-force time of calculation above-mentioned to(for) E-AGCH downlink subframes and E-HICH downlink subframes, suitable for uplink Bandwidth is the UMTS system of 5M, and the sending times of the next uplink E-DCH subframes of 5M bandwidth is 2ms, when upstream bandwidth be less than During the narrow bandwidth system of 5M, the time for sending a uplink E-DCH subframe is elongated, when bandwidth is 2.5M, uplink E-DCH subframes Duration becomes 4ms, and the time of downlink subframe is still 2ms, this is the sub-frame of uplink that 4ms is controlled with a 2ms downlink subframe, and It is not the sub-frame of uplink of original 2ms, therefore, the entry-into-force time of downlink subframe is also changed.It is original in order not to change The entry-into-force time of Downlink Control Information, an intermediate process to convert is added, detailed process is as follows：

When down control channel is E-AGCH channels or E-HICH channels, also wrapped in down control channel configuration information It includes：Compressibility factor N, the first index value of the first UE and the second index value of the 2nd UE, so that the base station is according to compressibility factor N 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 are calculated with 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, corresponding Second entry-into-force time received the second sub-frame of uplink that the 2nd UE is sent according to the second downlink control message.Meanwhile base station will be compressed The factor and index value are sent to the first UE and the 2nd UE, so that the first UE and the 2nd UE are receiving corresponding downlink control message Afterwards, the corresponding entry-into-force time is calculated according to compressibility factor and index value, the entry-into-force time then, control the transmission of sub-frame of uplink.

Wherein, compressibility factor N=sub-frame of uplink length/5M bandwidth UMTS sub-frame of uplink length or N=5M bandwidth/uplink The bandwidth of subframe, 5M bandwidth UMTS sub-frame of uplink length is 2ms, in asymmetric UMTS system, when sub-frame of uplink length is 4ms When, 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, uplink When frame transmission bandwidth is 2.5M, compressibility factor N=5/2.5=2, when sub-frame of uplink length is 8ms, the transmission bandwidth of sub-frame of uplink For 1.25M, compressibility factor N=5/1.25=4.The value range of Index 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 downlink subframe.In the present embodiment, the index values of the first UE are 0, the index values of the 2nd UE It is 1.

Assuming that base station sends E-AGCH subframes in j-th of subframe of i-th of system-frame to UE, base station is according to the following formula Calculate intermediate variable i ' and j '：

Wherein, N is compressibility factor, and Index is index value, and TF is System Frame Number conversion factor, the height that TF passes through network layer Layer signal deployment obtains, and the value range of TF is 0~N-1, and the value range of index is the integer of 0~N-1, the value range of i For 0~4095 integer, the value range of j is 0~4 integer, and mod represents complementation,Represent downward rounding operation. TF can be determined by RNC and be notified to base station, and UE is reinformed by base station, can also be determined by base station oneself, after TF is determined, base It stands and TF is informed into UE by way of high-level signaling.

Optionally, base station network equipment can also know constantly bandwidth less than 5M up-link carrier system System Frame Number and Subframe numbers and i ' and j ' can also be determined according to the System Frame Number i and j of the system of descending carrier system.Come by 2 citings of N It says, a total of 4096 of System Frame Number, number is followed successively by 0-4095, and when N is 2, bandwidth is less than to the up-link carrier system of 5M System Frame Number 4096 be divided into two parts, first part's number is 0~2047, and second part number is 2048~4095, If the System Frame Number i ' of up-link carrier system is 1110 when base station sends Downlink Control Information, which falls at first Point, TF value ranges are 0, if the System Frame Number j ' of up-link carrier system is fallen at second when base station sends Downlink Control Information Point, TF values are 1.Therefore, in System Frame Number in 0~2047, TF is configured to 0 by base station, System Frame Number for 2048~ In 4095, TF is configured to 1 by base station.TF can be determined by RNC and be notified to base station, and UE is reinformed by base station, can also be by base It stands and oneself determines, after TF is determined, TF is informed UE by base station by way of high-level signaling.

Further, base station is determining i ' and j ' after, according to i ' and j ' and the following formula determines time offset s and t:

Wherein, τ_DPCH,nFor the frame shifting amount of Dedicated Physical Control Channel DPCH channels,Expression rounds up operation,Represent downward rounding operation, i ' value ranges are 0~4095 integer, and the value range of j ' is 0~4 integer, are being determined After s and t, then 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 is understood, and at this Entry-into-force time then, receives the sub-frame of uplink that UE is sent.

For E-HICH downlink subframes, the phase of the calculation formula of intermediate variable i ' and j ' and above-mentioned E-AGCH subframes Together, but the calculation of time offset s and t is different, and s and t are calculated by the following formula：

T=(j'+2) mod5,

Wherein,Represent downward rounding operation, mod represents complementation, and the value range of j ' is 0~4 integer, E- The downlink control message sent in HICH downlink subframes comes into effect, and in t-th of subframe of the i-th '-s system-frames in life It imitates the time then, receives the sub-frame of uplink that UE is sent.

Method provided in this embodiment, also can be under in the case of the computational methods for not changing the existing entry-into-force time The transmission of sub-frame of uplink in row subframe control uplink narrow bandwidth UMTS network.

By the above-mentioned description to F-DPCH, DPCCH, E-AGCH, E-HICH, E-RGCH channel it is found that by being configured two A UE is aligned using identical channel code and subframe timing so that base station, can be to two UE points in the downstream cycle of 4ms Not Fa Song a 2ms downlink subframe, 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 Channel, E-RGCH channels are different, and AICH channels belong to shared channel.In one cell, in UE access, all UE can Access lead information is sent using two multi-upstream access channels, and base station is accessed when sending downlink access instruction information to UE It can be the access request for receiving UE or the access request for refusing UE to indicate information, and all UE are believed using shared AICH Road sends downlink access instruction information, and two multi-upstream access channels correspond to two uplink sub-carriers, and AICH channels are corresponded under one Row subcarrier.Therefore, a descending carrier corresponds to two subcarriers of uplink, and two multi-upstream access channel timings are based on same The down channel of sample, when base station receives the access lead information that two UE are sent by two multi-upstream access channels simultaneously, It base station can only be to by AICH channels, a UE sends access instruction information, therefore asking there are downlink instruction conflict thereto Topic.In asymmetric uplink and downlink carrier system, when 2 users access simultaneously from different sub-carrier, it is impossible at the same to 2 users into Row accurately access control.In the prior art, for the different Physical Random Access Channels under a carrier wave（Physical Random Access Channel, abbreviation PRACH）Different values can be configured in the timing slip of corresponding AICH channels, when After two UE send access lead information using the different PRACH channels of same subcarrier, base station receives two UE simultaneously The access lead information of transmission, since different PRACH channels are different from the timing slip of AICH channels, base station is not Same time slot sends access instruction information to two UE respectively, will not there are problems that accessing instruction conflict.
