Fig. 1 show according to embodiments of the present invention the indicative flowchart of the method 100 in definite decoding moment really. The method 100 can be performed by subscriber equipment or the network equipment, for instance, the method 100 can realize in the baseband processor of subscriber equipment, and this is not limited as by the embodiment of the present invention, as it is shown in figure 1, the method 100 includes:
S110, obtains the time slot of initial start decoding in each TTI at least one Transmission Time Interval TTI, and this at least one TTI includes a TTI, and a TTI is last TTI in this at least one TTI;
S120, according to the time slot of initial start decoding in this each TTI and the reference time territory preset, it is determined that the first time slot of the initial start decoding in the 2nd TTI, the 2nd TTI is the next TTI of a TTI.
It should be noted that, because FET technology is when the not yet complete data received in whole TTI, a period of time trial and error decoding in advance, so in a TTI likely can frequent trial and error decoding, in each TTI in the embodiment of the present invention, the time slot of initial start decoding refers to the time slot of first time trial and error decoding in this TTI.Additionally, in each TTI, the time slot of initial start decoding is for each TTI, namely start calculating with the initial time in each TTI, rather than for whole time shaft, therefore, popular, the moment of the time slot of the initial start decoding decoding that can also be called in each TTI initial start in each TTI, because the duration of the time slot under different communication systems is different (such as, in LTE communication system, 1 time slot is 1 millisecond, and in WCDMA system, 1 time slot is 2/3 millisecond), succinct in order to describe, embodiment of the present invention unification time slot represents the concept in moment, it should be understood that, with time slot describe the moment be only used to describe convenient, and the embodiment of the present invention should not constituted any restriction, the embodiment of the present invention can also use millisecond, second etc. describes the moment of initial start decoding.
In prior art, FET technology is intended to fulfil ahead of schedule decoding thus the radio frequency unit closing on link is to reduce power consumption, and for moment of initial start decoding often by producer's designed, designed, therefore, the moment of the initial start decoding of prior art is fixed often. But owing to wireless channel environment is changeable, adopt the moment of fixing initial start decoding, if wireless channel environment is poor and/or the decoding performance of communication equipment becomes poor, the generation of frequently decoding can be caused, and frequent starting decoding can cause power dissipation overhead to increase and system loading increases, power consumption increase necessarily affects the effect of FET performance itself, and system loading increases, and understands the overall task scheduling of influential system and timing requirements.
For these reasons, the embodiment of the present invention proposes a kind of method determining the decoding moment, can according to the moment of the Initial Decoding in nearest one or more TTI, determine the moment that the initial start in next TTI decodes, because the moment of the initial start decoding in previous or front several TTI, the decoding performance of up-to-date wireless channel environment and/or communication equipment can be reacted, therefore, the method in embodiment of the present invention definite decoding moment really can according to the decoding performance of real-time wireless channel environment and communication equipment, determine the moment of initial start decoding in next TTI, thus avoiding the generation of frequently decoding, the power dissipation overhead brought frequently is decoded therefore, it is possible to effectively reduce.
Specifically, after subscriber equipment receives DLDPCH, the coded system that can adopt DLDPCH carries out corresponding decoding process, therefore, subscriber equipment can obtain its time slot in each TTI, this DLDPCH initial start decoded, thus, the time slot that subscriber equipment can decode according to the initial start of history, it is determined that the time slot of the initial start decoding in TTI on the horizon. first subscriber equipment can obtain the time slot of the initial start decoding in each TTI at least one TTI, alternatively, this subscriber equipment can obtain the time slot of the initial start decoding of (hereinafter referred to as " TTI ") in current TTI, the time slot that the initial start in the multiple TTI including a TTI decodes can also be obtained, such as, this subscriber equipment can arrange an observation window, obtain the time slot that the initial start in each TTI in this observation window decodes, this observation window can slide along with the change of a TTI backward, thus this subscriber equipment can obtain real-time reference data. after this subscriber equipment obtains the data that the initial start in one or more TTI decodes time slot, the time slot that can decode according to the initial start in these one or more TTI, determine the time slot of the initial start decoding of (hereinafter referred to as " the 2nd TTI ") in the next TTI of a TTI, such as, if this at least one TTI only includes a TTI, the time slot that can decode according to the initial start in a TTI, determine the time slot of the initial start decoding of the 2nd TTI, if or this at least one TTI includes multiple TTI, can according to the time slot of initial start decoding in each TTI in the plurality of TTI, determine the time slot that the initial start in the 2nd TTI decodes.Such as, if before in a TTI, the time slot of initial start decoding is positioned at this reference time territory, the first reference time slot is it is believed that initial start decoding is too early, now, the time slot that initial start in 2nd TTI decodes can be delayed, to improve decoding performance and to reduce power consumption; Or the meansigma methods of the time slot that can decode according to the initial start in each TTI in multiple TTI, determine the time slot that the initial start in the 2nd TTI decodes, alternatively, if this average bits is after this reference time territory, that is the time slot of average initial start decoding is later than this second reference time slot, it is believed that initial start decodes too late, likely affect FET and reduce the purpose of power consumption, now, the time slot initial start of the 2nd TTI decoded can be selected to shift to an earlier date, to improve the characteristic of the reduction power consumption of FET.
Should be understood that in embodiments of the present invention, illustrate using subscriber equipment as executive agent and be only used to example, and the embodiment of the present invention should not constitute any restriction, the embodiment of the present invention can also be performed by other network equipments, for instance, base station etc. Additionally, the embodiment of the present invention with subscriber equipment to downward special physical channel (English full name: DownlinkDedicatedPhysicalChannel, it is called for short: DLDPCH) carry out decoding and process to illustrate for example and be only used to example, the embodiment of the present invention can be also used for the subscriber equipment decoding to other data and processes, or can be used for the network equipment decoding process etc. to the data of its reception.
Will also be understood that, this reference time territory can be that the first reference time slot and second is with reference to the time domain between time slot, this reference time territory can be a time point (that is this first reference time slot and this second reference time slot overlap), can also being a time period, this be not limited as by the embodiment of the present invention. Alternatively, this first reference time slot and second can obtain according to link simulation with reference to time slot, and this first reference time slot and second can change with the change of successfully decoded time slot with reference to time slot. This first reference time slot and second can be understood as the one period of reference time that preferably Initial Decoding starts considering the aspect performance such as decoding performance and system power dissipation with reference to the reference time territory between time slot, if starting decoding before this first reference time slot, it is likely to result in the generation of frequently decoding, thus causing system power dissipation to increase, if instead starting decoding after this second reference time slot, it is likely to result in starting decoding too late, affects FET and reduce the performance of power consumption.
Alternatively, as an embodiment, this at least one Transmission Time Interval only includes a TTI, and this is according to the time slot of initial start decoding in this each TTI and the reference time territory preset, it is determined that the first time slot of the initial start decoding in the 2nd TTI, including:
If this second time slot is later than this second reference time slot, it is determined that this first time slot is that this second time slot deducts the time slot that the first step is looked; Or
If this second time slot is early than this second reference time slot, it is later than this first reference time slot, it is determined that this first time slot is the 3rd time slot being in this reference time territory.
Specifically, when this at least one TTI only includes a TTI, this subscriber equipment can according in a TTI initial start decoding the second time slot and this reference time territory, it is determined that in the 2nd TTI initial start decoding the first time slot. alternatively, if this second time slot is later than right margin that is second in this reference time territory with reference to time slot, that is, the successful time slot of time slot Distance Decoding of initial start decoding is close, or it is exactly successfully decoded time slot, explanation decoding performance is fine, now such as the time slot of not pre-cooling Initial Decoding, the time slot that may result in starting decoding is partially late, affect FET and reduce the effect of power consumption, it is thus desirable to the time slot of the initial start decoding shifted to an earlier date in the 2nd TTI, alternatively, this the second time slot can be deducted the time slot that the first step looks and be defined as the first time slot, that is time after this second time slot drops on this reference time territory, the time slot of initial start decoding in next TTI can be shifted to an earlier date, to be reduced the effect of power consumption by FET.Alternatively, this first step-length can be set so that the step-length that this first time slot is in this reference time territory, such as, if this first reference time slot is time slot 14, this the second reference time slot is time slot 17, this second time slot is time slot 18, then this first step-length can take the arbitrary value in 1 time slot～4 time slot, so that this first time slot can drop in time slot 14～time slot 17 scope. alternatively, if this second time slot is early than this second reference time slot, it is later than this first reference time slot, that is this second time slot has been in this reference time territory, now, may determine that this second time slot is this first time slot, that is the time slot that time slot that the initial start of a TTI decodes can be decoded as the initial start of the 2nd TTI, or the time slot that the 3rd time slot decodes as the initial start of the 2nd TTI can also be selected in this reference time territory, 3rd time slot can be this second time slot, can also be other time slots in this reference time territory except this second time slot, this is not limited as by the embodiment of the present invention. alternatively, if this second time slot is early than this first reference time slot, the time slot that this second time slot obtains plus a step-length can be defined as the first time slot, that is the moment of initial start decoding is too early, next TTI needs delay start to decode, and this step-length can be the step-length making this second time slot be in this reference time territory.
It should be noted that, because when the time slot of initial start decoding falls in this reference time territory, often think that the time slot of initial start decoding of next TTI is without adjusting, or only need to be adjusted to other slot values in this reference time territory, therefore, this reference time territory can also be called maintenance territory, meanwhile, this the first reference time slot is properly termed as initial maintenance time slot, this the second reference time slot is properly termed as termination and keeps time slot, that is in embodiments of the present invention, this reference time territory can be general with maintenance territory, this first reference time slot and initial maintenance time slot can be general, this second reference time slot and initial maintenance time slot can be general.
Alternatively, as an embodiment, this first step-length is so that this first time slot is in the step-length in this reference time territory; Or the 3rd time slot be this second time slot.
Specifically, this first reference time slot can use Tref1Representing, this second reference time slot can use Tref2Representing, the interval of this first reference time slot and this second reference time slot can use TgapRepresent, wherein, this Tgap=Tref2-Tref1, this second time slot T2Represent, the first time slot T of the 2nd TTI to be determined1Represent. If the second time slot is later than second with reference to time slot, namely T2<Tref2, it is determined that the first time slot is that the second time slot deducts the first step-length, this first step-length S1Can be the step-length making this first time slot be in reference time territory, say, that Tref1≤T1=T2-S1≤Tref2, then S1Span can be T2-Tref2≤S1≤T2-Tref1, alternatively, as an embodiment, this first step-length can be make the step-length that this first time slot can be the meansigma methods of this first reference time slot and this second reference time slot. I.e. T1=T2-S1=Tref1+Tgap/ 2, then this S1=T2–(Tref1+Tgap/2)。
Alternatively, if this second time slot itself has been in this reference time territory, then the 3rd moment can be this second time slot, the time slot that time slot is the 2nd TTI initial start decoding of the initial start decoding of a TTI namely can directly be determined.
It should be noted that the time slot that above-described subscriber equipment decodes according to the initial start in a TTI, it is determined that the method for the time slot of the initial start decoding in the 2nd TTI is properly termed as fast adjustment algorithm;Similarly, the meansigma methods of the time slot that this subscriber equipment decodes according to the initial start in each TTI in multiple TTI, determine that the method for the time slot of the decoding of the initial start in the 2nd TTI is properly termed as slow adjustment algorithm, when the second time slot is unsatisfactory for two Rule of judgment of fast adjustment algorithm, (the second time slot is later than this second with reference to time slot, or second time slot early than this second with reference to time slot, it is later than this first reference time slot) time, can select to adopt slow adjustment algorithm to determine the first time slot, be described in detail below and then determine this first time slot according to this slow adjustment algorithm.
Alternatively, as another embodiment, this at least one Transmission Time Interval includes multiple TTI, this according in this each TTI initial start decoding time slot and reference time territory, it is determined that in the 2nd TTI initial start decoding the first time slot, including:
Determine the first meansigma methods of the time slot of initial start decoding in each TTI in the plurality of TTI;
If this first meansigma methods is early than this first reference time slot, it is determined that this first time slot is the time slot that this first meansigma methods is looked plus second step.
Specifically, if this second time slot is unsatisfactory for the Rule of judgment of fast adjustment algorithm, namely this second time slot is unsatisfactory for being later than second with reference to time slot, or it is in the Rule of judgment in this reference time territory, now, this subscriber equipment can according to the time slot of the initial start decoding in each TTI in the multiple TTI obtained, determine first meansigma methods of time slot of initial start decoding in this each TTI, then determine, according to this first meansigma methods, the first time slot that the initial start in the 2nd TTI decodes, particularly, this subscriber equipment can add up nearest several TTI (such as, 5 TTI) in each TTI in initial start decoding time slot, determine the first meansigma methods of the time slot of the initial start decoding of these these TTI, then according to the relation by this first meansigma methods Yu this reference time territory, determine this first time slot. alternatively, if this first average bits is before this reference time territory, namely this first meansigma methods is early than this first reference time slot, it is believed that the time slot of initial start decoding is too early, it is likely to occur decoding failure frequently, could be successfully decoded, it is thus desirable to delay the time slot of initial start decoding, now, time slot by this first meansigma methods is looked plus second step can be set and be defined as this first time slot, alternatively, this second step-length can be the particular step size making this first time slot be in this reference time territory, or consider the polytropy of channel circumstance, one time slot progressively adjusting the Initial Decoding in next TTI less than the less step-length of this particular step size can also be set, so that the position that this first time slot Step wise approximation is successfully decoded. alternatively, as an embodiment, this second step-length can be the half of this second reference time slot and the interval of this first meansigma methods. alternatively, if this first meansigma methods is in this reference time territory, this first time slot can be this first meansigma methods, can also be other time slots in this reference time territory, if or this first meansigma methods is later than this second reference time slot, that is the time slot of initial start decoding is too late, this first meansigma methods now can deduct the time slot that a step-length obtains and be defined as this first time slot.
The method of determining decoding moment is discussed in detail below in conjunction with specific embodiment, in the embodiment shown in Figure 2,1 TTI is 20ms, including 30 time slots (time slot 0～time slot 29), reference time territory (maintenance territory) is time slot 14～time slot 17, and namely first with reference to time slot Tref1For time slot 14, the second reference time slot is time slot 17, and successfully decoded time slot is time slot 20.
It should be understood that, in each TTI, subscriber equipment can obtain the second time slot of the initial start decoding in current TTI, and includes the time slot of the initial start decoding of multiple TTI of current TTI, the time slot of the concrete initial start decoding obtained in how many TTI, it is possible to arranged by subscriber equipment. Then judge whether this second time slot meets the Rule of judgment of fast adjustment algorithm, if meeting, then determine this first time slot according to fast adjustment algorithm, otherwise, determine this first time slot according to slow adjustment algorithm.
In the scene one shown in Fig. 2, the second time slot T of initial start decoding in a TTI2For time slot 18, it is thus necessary to determine that the first time slot T of initial start decoding in the 2nd TTI1。
After subscriber equipment obtains above-mentioned data, first determine whether whether this second time slot meets the Rule of judgment of fast adjustment algorithm, namely whether this second time slot is later than second with reference to time slot, or whether this second time slot is positioned at this maintenance territory, generally speaking, namely determine whether this second time slot is later than this first reference time slot, if this second time slot is later than this first reference time slot, then the first time slot can be determined according to fast adjustment algorithm. In scene one, this second time slot is later than this second reference time slot, say, that, in oneth TTI, the successful time slot of moment Distance Decoding of initial start decoding is close, and decoding performance is fine, it is necessary to decodes to reach FET in advance and reduces the purpose of power consumption, now, it is alternatively possible to by this second time slot T2Deduct the first step-length S1After time slot be defined as the first time slot T1。
Alternatively, this first step-length can be make this first time slot be in the step-length kept in territory. For scene one, i.e. time slot 14≤T2-S1≤ time slot 17, i.e. 1 time slot≤S1≤ 4 time slots, alternatively, however, it is determined that this first time slot is the time slot 16 in this maintenance territory, then this S1Can be 2 time slots.
In the scene two shown in Fig. 2, the second time slot T of initial start decoding in a TTI2For time slot 16, it may be determined that this second time slot is in this maintenance territory, it is possible to adopt fast adjustment algorithm to determine this first time slot. Because this second time slot is in this maintenance territory, it is alternatively possible to any time slot determined in this maintenance territory is this first time slot, it is also possible to this second time slot is defined as this first time slot, the time slot of the namely initial start in next TTI decoding remains unchanged, i.e. T1For time slot 16.
In the scene three shown in Fig. 2, in multiple TTI, the first meansigma methods of initial start decoding is time slot 9, early than this first reference time slot, therefore, it is adaptable to adopt slow adjustment algorithm to determine this first time slot.
Alternatively, the time slot by this first meansigma methods is looked plus second step can be adopted to be defined as the first time slot, this second step-length can be make moment one successive step of initial start decoding in next TTI to the step-length in this reference time territory, it is also possible to for making to start the step-length of the successfully decoded time slot of the time slot Step wise approximation decoded. Alternatively, this second step-length can be the half of this second reference time slot and the interval of this first meansigma methods, i.e. S2=(Tref2-T1)/2, T here1For this first meansigma methods, the concrete data in substitution scene three, this S2=4 time slots.
Therefore, the method in definite decoding moment really according to embodiments of the present invention, can according to the Initial Decoding moment in nearest one or more TTI, determine the moment that the initial start in next TTI decodes, thus avoiding the generation repeating decoding, effectively reducing and frequently decoding the power consumption brought and system load expense.
