Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, the present invention is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
Basic thought of the present invention is: at the These characteristics of TDD CPC project business in the TDD system, reduce when the descending scheduling expense to the HS-SCCH resource by the blind check technology of optimizing.
In order clearly to describe the present invention, at first carry out brief description below with regard to existing blind check technology:
Existing blind check technology is applied in the FDD system, it is meant under the situation of not using the HS-SCCH scheduling resource, by the UE possible resource informations such as data block size good according to configured in advance, resolving those may be the data block that sends to this UE, to determine to belong to the data block of this UE.When parsing is correct, then can determine to dispose data block size to described UE, in the time can not correctly resolving, illustrate that then transfer of data makes a mistake or described data block does not belong to described UE to data.Like this, can make system when dispatching, not need to give a certain UE by blind check, but can in a certain scope, therefrom select operable resource to be configured according to actual needs, thereby increase the flexibility of scheduling fixing a certain resource distribution.
Because existing blind check Technology Need carries out blind check on all subframes, computation complexity and power consumption that this will increase UE are not suitable in the TDD system.For this reason, the present invention optimizes it, specifies by the predefine resource information to exist data burst and/or time slot to dwindle the blind check scope, thereby reduces computation complexity and the power consumption of UE.
Fig. 1 is the exemplary process diagram of the inventive method, and this method mainly may further comprise the steps:
Step 101, system are in the UE configuration predefine resource information of network terminal for scheduling, and described predefine resource information comprises: the subframe scope of the spread spectrum code resources information of use, the data block magnitude range of use, carrying data and the time slot scope of carrying data.
Here, the subframe scope of carrying data is for existing the subframe of data, and the time slot scope of carrying data is for may carry the time slot of data.System can be chosen on a plurality of time slots of certain subframe, perhaps on a plurality of subframes time slot, perhaps carries data on a plurality of time slots of a plurality of subframes.
Need to prove, N time slot of certain subframe carry out blind check (2≤N), carry out blind check than certain time slot on N subframe, its flexibility is identical, and the computation complexity of UE and power consumption can be littler.Because, even time slot UE of blind check also needs to receive earlier the signal on all time slots of this time slot place subframe, therefore for the situation of a time slot of blind check on N subframe, UE need receive the signal on all time slots of N subframe, and for the situation of blind check in N time slot blind check of a subframe, then the UE signal that only need receive on all time slots of a frame gets final product.But number mostly is three most in the descending time slot owing to each subframe in the existing system comprises, so, when needs enlarge available scope of resource, when improving dispatching flexibility, then need by a plurality of frames of data that may exist are realized.
Therefore, system can be according to actual needs, by disposing those subframe that may have data and time slots, averages out between the complexity of the flexibility of scheduling and UE and power consumption.
In actual applications, the subframe scope that the carrying data are set can have multiple mode, can indicate each subframe whether may carry data one by one, thus the subframe scope of indication carrying data; Perhaps, also can be in the cycle that constitutes by a plurality of subframes, the part subframe that is provided with in this cycle may be carried data, thereby makes the subframe scope of carrying data be periodic distribution.Particularly, when the subframe scope of indication carrying data, also can adopt multiple mode accordingly: for example: can utilize the form of bitmap, whether subframe of each expression may carry data; Also can indicate the number of sub-frames and the Cycle Length that may carry data after the initial subframe number that may carry data in each cycle, the described initial subframe continuously; Perhaps pre-configured tabulation and the corresponding index that comprises the multiple subframe scope that constitutes by cycle and described assigned address, just can obtain the subframe scope that may carry data of actual use according to index value, the subframe range list that example 6 bits of use as shown in table 1 are represented:
Call number The subframe scope
0 All may carry data on each subframe
1 May carry data on the odd number subframe
2 May carry data on the even number subframe
3 With 4 subframes is the cycle, may carry data on the 1st subframe in each cycle
4 With 4 subframes is the cycle, can carry data on the 2nd subframe in each cycle
5 With 4 subframes is the cycle, may carry data on the 3rd subframe in each cycle
6 With 4 subframes is the cycle, may carry data on the 4th subframe in each cycle
7 With 4 subframes is the cycle, may carry data on the 1st, 2 subframe in each cycle
8 With 4 subframes is the cycle, may carry data on the 2nd, 3 subframe in each cycle
????9 With 4 subframes is the cycle, may carry data on the 3rd, 4 subframe in each cycle
????10 With 4 subframes is the cycle, may carry data on the 4th, 1 subframe in each cycle
????11 With 4 subframes is the cycle, may carry data on the 1st, 3 subframe in each cycle

????15 With 8 subframes is the cycle, may carry data on the 3rd, 6,1 subframe in each cycle
????16 With 8 subframes is the cycle, may carry data on the 4th, 7,2 subframes in each cycle
????…… ……
Table 1
Only to utilizing the part subframe scope in the subframe range list that 6 bits represent to illustrate, other subframe scope method to set up is similar to listed subframe scope, lists no longer one by one herein in the table 1.Here need to prove, consider the computation complexity of UE, the number of sub-frames that may carry data weekly in the phase generally can not surpass 3/4ths of the cycle, and for example when the cycle was 8, the number of sub-frames that may carry data weekly in the phase can not be above 6.
The indicating mode of the time slot scope of carrying data is similar with the indicating mode of the subframe scope of carrying data, for example, can utilize the mode of bitmap, and wherein whether time slot of each expression may carry data; Other mode repeats no more herein.
Step 102, system are notified to UE with described predefine resource information.
Here, the concrete grammar that described predefine resource information is notified to UE is:
The described predefine resource information of determining directly is handed down to described UE by the high-level signaling or the first special HS-SCCH channel;
Perhaps,
In UE and system, preset the combination information list in advance, the tabulation of described combined information comprises the combination of subframe range information and corresponding every kind of call number that combination is provided with of data block magnitude range and carrying data, and the time slot scope of the carrying data that the described predefine resource information of determining is comprised, spread spectrum code resources information and predefine resource information corresponding call number in described combined information tabulation of use are handed down to described UE.
Step 103, system are defined as spread spectrum code resources, the data block size of described UE scheduling, the subframe and the time slot of carrying data in described predefine resource information restricted portion.
Here, system will dispatch in described predefine resource information restricted portion, when packet of the first biography of each transmission cycle, system can be according to actual conditions, in described scope is described UE scheduling resource, like this, can in described scope, dispatch different resources during each transmits data packets, thereby can increase the flexibility of system call.
In actual applications, when system at every turn to UE is first when passing a packet, need be in described predefine resource information restricted portion in system, being defined as described UE scheduled resources information is the subframe and the gap information of spread spectrum code resources, data block size, carrying data.
Step 104, UE carry out blind check to the data that receive in described predefine resource information restricted portion, determining system during to correct data when blind check is described spread spectrum code resources, the data block size of its scheduling, the subframe and the time slot of carrying data.
Here, described blind check is meant and carries out in the subframe of the specified spread spectrum code resources of described predefine resource information, data block size, carrying data and time slot scope.That is to say that UE described in this step will attempt respectively utilizing in spread spectrum code resources, data block size, the subframe of carrying data and the time slot scope that described predefine resource information limits and carry out data parsing, till resolving correct or parse error.
In actual applications, for the business that the transmission of packet has characteristics periodically, in each transmission cycle of active period, send a packet as the VoIP business, be that every 20ms sends a packet, in each transmission cycle of quiet period, send a packet, be that every 160ms sends a packet, when correctly having received a packet in the transmission cycle of terminal in active period or quiet period, just there is no need to continue again from HS-DSCH channel blind check data.
Therefore, when can correctly the system of being resolved to sends data in the blind check process of UE in step 103, then no longer carry out blind check in the current data transmission cycle, described data transfer cycle is the transmission cycle of active period or quiet period.Can reduce algorithm complex and the power consumption of UE by this method, make full use of system resource.
In addition, the present invention is by redefining the partial information among the existing HS-SCCH, obtain three special HS-SCCH, the i.e. first special HS-SCCH, the second special HS-SCCH and the 3rd special HS-SCCH, they be respectively applied for control UE to configuration/renewals of its predefine resource information, discharge and to UE transmission retransfer scheduling information.The specifying information that above-mentioned special HS-SCCH carries will be described in detail in the embodiment of the invention one.

Wherein, it is 0 that the transport block size information field is made as complete 0 expression data block size, and this does not have practical significance.In addition, the HARQ procedural information of 3 bits, the redundancy version information of 3 bits, the new data indication of 1 bit and the cyclic sequence sign indicating number information of 3 bits do not need to comprise in the predefine resource information yet.
Therefore, can utilize in the present embodiment and be made as complete 0 transport block size information field and represent that this is a special HS-SCCH channel.In addition, 10 bits that obtain after utilizing the cyclic sequence sign indicating number information of the new data indication of the redundancy version information of the HARQ procedural information of 3 bits, 3 bits, 1 bit and 3 bits to merge, represent special HS-SCCH type and the part predefine information relevant with the special HS-SCCH of the type, wherein, 2 bits are represented the type of special HS-SCCH, and 8 bits are represented the part predefine information relevant with the special HS-SCCH of the type.Here, 2 bits of the special HS-SCCH type of above-mentioned expression are got up to constitute channel type identification information field with the transport block size information field combination that is made as complete 0, it is a special HS-SCCH channel that this channel type identification information field is used to indicate this HS-SCCH, and further to indicate it be any in the multiple special HS-SCCH channel, and promptly HS-SCCH is first, second or the 3rd special HS-SCCH.In actual applications, UE according to channel type identification information field determine the HS-SCCH type preferred mode can for: whether 6 bits that detect earlier described transport block size information field are 0 entirely, if judge this HS-SCCH again is special HS-SCCH, and then be used to represent 2 bits of special HS-SCCH type by detection, judge the particular type of this special HS-SCCH, otherwise will can not detect this 2 bits again.The specifying information form of the special HS-SCCH channel of each that use in the present embodiment will describe in detail in idiographic flow:
Among the embodiment one, be example, only implement the present invention, when retransmitting, then utilize existing HS-SCCH channel to realize descending scheduling at the data of transmission first with the VOIP business.Utilize the flow chart of Fig. 2 for the embodiment of the invention one.As shown in Figure 2, embodiment one comprises:
Step 201, system are in the UE configuration predefine resource information of network terminal for scheduling, and described predefine resource information comprises: the data block magnitude range of use, and the time slot scope of the subframe scope of carrying data and carrying data.
Step 202, system are notified to UE by the first special HS-SCCH channel with described predefine resource information.
Here, the coding of the described first special HS-SCCH channel comprises: the channel type identification information, be used to indicate the spread spectrum code resources of use channel code collection information, be used to indicate the carrying data the time slot scope gap information and be used to indicate the modulation scheme information of modulation scheme, and be used for the data block size information of designation data block size scope and be used to indicate the sub-frame information of the subframe scope of carrying data.
In the present embodiment, the first special HS-SCCH chnnel coding is:
The channel code collection information (Channelisation-code-set information) of 8 bits: the spread spectrum code resources that is used to indicate use;
The gap information of 5 bits (Time slot information): be used to indicate the time slot scope of carrying data, promptly may have the time slot of data; Wherein, the corresponding time slot of bit, whether expression UE needs this time slot of blind check, and whether system can dispatch this UE on this time slot, and here, 5 bits correspond respectively to time slot 2,3, and 4,5 and 6;

Step 203, system are defined as spread spectrum code resources, the data block size of described UE scheduling, the subframe and the time slot of carrying data in described predefine resource information restricted portion.
Step 204, UE carry out blind check to the data that receive in described predefine resource information restricted portion, when blind check during to correct data, determine that system is described spread spectrum code resources, the data block size of its scheduling, the subframe and the time slot of carrying data.
More than be to utilizing the main flow process of the downlink dispatching method that blind check realizes in the present embodiment one.In actual applications, when needs upgrade the predefine resource (for example: when active period enters quiet period, perhaps when quiet period enters active period), can give UE according to method in the abovementioned steps 102 with the predefine resource notification with the new subscription justice resource information of determining, after this UE will be according to new predefine resource reception/transmission data.
In actual applications, because when quiet period, professional volume of transmitted data is few, system's continuation uses the predefine resource information of active period will increase computation complexity and the power consumption of UE, and will cause resource waste, the present invention proposes the method for two kinds of optimizations, a kind of is that quiet period adopts different predefine resources with active period, the scope of resource that may carry data that the predefine resource information that wherein quiet period adopted limits can be littler than restricted portion in the predefine resource information that is adopted in active period, can reduce blind check complexity and the power consumption cost of UE like this; Another kind is that UE need discharge the predefine resource when entering quiet period, will adopt existing HS-SCCH dispatching method in quiet period.If a kind of method before adopting need be upgraded described predefine resource information when UE changes between active period and quiet period.If adopt a kind of method in back, when UE when active period is transformed into quiet period, system will need to notify UE to discharge described predefine resource information, as UE during from quiet period to active period, then system will need to dispose described predefine resource information for UE.
In the present embodiment, when needs discharge described predefine resource information, for example from the active period to the quiet period, system discharges described predefine resource information by the described second special HS-SCCH channel notification UE, comprises the channel type identification information in the information of the described second special HS-SCCH channel.After UE discharges described predefine resource information, will no longer utilize blind check method of the present invention, and be to use existing HS-SCCH channel to carry out descending scheduling.
Here, carry out the release of predefine resource information by channel type identification information indication UE, that is to say, when UE according to the channel type identification information in the second special HS-SCCH channel, when judging this channel and be the second special HS-SCCH channel, will discharge described predefine resource information.
In the present embodiment, the information format that the described second special HS-SCCH channel is comprised is:
