Description

一种用户设备 UE的发射功率控制方法及装置技术领域本发明涉及宽带码分多址*** （Wideband Code Division Multiple Access, 简称 WCDMA) 的外环功率控制（Outer Loop Power Control, 简称 OLPC)，特别涉及一种用户设备 UE的发射功率控制方法及装置。背景技术在 WCDMA中可通过上行功率控制实现对用户发射功率的控制，从而使得用户上行业务质量（比如误块率（Block Error Rate, 简称 BLER) 等指标）达到一定的目标水平。在进行功率控制时，由外环功控（Outer Loop Power Control, 简称 OLPC)基于业务的质量目标确定目标信干比（Signal to Interference Ratio target, 简称 SIR target), 并由内环功控（Inner Loop Power Control)基于当前测量的信干比（Signal to Interference Ratio, 简称 SIR) 和目标信干比（SIR target) 的大小关系调整 UE的发射功率。目标信干比的确定是功率控制的关键，目标信干比太低则会影响业务质量，但如果目标信干比太大也会造成功率增加从而影响***容量。但在实际应用中，为了获得较高的业务建立成功率等指标，一般都需要将初始目标信干比（Initial SIR target) 设得比保证业务质量所需的目标信干比要大一点，而在采用常用的基于业务质量（Quality of Server, 简称 QoS) 调整目标信干比的方法时，由于业务质量的判断需要基于一定量的传输块等信息，所以下调目标信干比的速度往往较慢，这样会导致 UE在初始阶段较长时间内目标信干比偏大，即 UE在较长时间内功率偏大，从而降低了***容量。所以需要有一种快速收敛目标信干比的方法，既能满足较大初始目标信干比的需求，又能将初始目标信干比从较高的水平快速收敛到基于业务质量考虑所需的正常水平上，使得在保证用户具有较高的初始信道质量的同时，减少对***容量的损失。本发明提供了一种用户设备 UE的发射功率控制方法及装置，从而提高***容量。发明内容本发明的目的在于提供一种用户设备 UE的发射功率控制方法及装置，能更好地提升***容量。根据本发明的一个方面，提供了一种用户设备 UE的发射功率控制方法。根据本发明的另一方面，提供了一种实现上述方法的装置。根据本发明的一个方面，提供了一种用户设备 UE的发射功率控制方法，包括以下步骤：根据业务质量目标确定并调整目标信干比；通过测量当前接收信号质量得到测量信干比；按照所述测量信干比逼近所述目标信干比的方式，调整 UE的发射功率，使调整后的发射功率与所述目标信干比相适应。 The present invention relates to an Outer Loop Power Control (OLPC) of a Wideband Code Division Multiple Access (WCDMA) system, and more particularly to A method and apparatus for controlling transmission power of a user equipment UE. BACKGROUND In WCDMA, uplink power control can be used to control user transmit power, so that user uplink service quality (such as Block Error Rate (BLER)) can reach a certain target level. In the power control, the Outer Loop Power Control (OLPC) determines the target to interference ratio (SIR target) based on the quality target of the service, and is controlled by the inner loop (Inner Loop). Loop Power Control) adjusts the transmit power of the UE based on the magnitude relationship between the currently measured Signal to Interference Ratio (SIR) and the target SIR target. The determination of the target signal-to-interference ratio is the key to power control. If the target signal-to-interference ratio is too low, it will affect the quality of service. However, if the target signal-to-interference ratio is too large, the power will increase and the system capacity will be affected. However, in practical applications, in order to obtain higher service establishment success rate and other indicators, it is generally required to set the initial target SIR target to be larger than the target signal-to-interference ratio required to ensure the quality of the service. When the method of adjusting the target signal-to-interference ratio based on the quality of service (QoS) is used, since the judgment of the service quality needs to be based on a certain amount of information such as the transport block, the speed of lowering the target signal-to-interference ratio is often slower. In this way, the target signal-to-interference ratio of the UE is too large in the initial period, that is, the UE is too large in a long time, thereby reducing the system capacity. Therefore, there is a need to quickly converge the target signal-to-interference ratio (SNR) ratio, which can meet the requirements of a large initial target signal-to-interference ratio, and can quickly converge the initial target signal-to-interference ratio from a higher level to the normality required for service quality considerations. Horizontally, the loss of system capacity is reduced while ensuring that the user has a higher initial channel quality. The present invention provides a method and apparatus for controlling transmission power of a user equipment UE, thereby improving system capacity. SUMMARY OF THE INVENTION An object of the present invention is to provide a method and apparatus for controlling transmission power of a user equipment UE, which can better improve system capacity.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings. In this document, the target signal-to-interference ratio (SIR target) in the outer loop power control (OLPC) is divided into two parts, one part satisfies the target quality of service (QoS) requirements in the steady state, and the other part satisfies the higher quality requirements in the initial stage of the service. The two components adopt different adjustment methods to achieve the dual requirements of service quality and system capacity, and the calculation method of the two components is more practical and simple, and has less influence on the system processing load. FIG. 1 is a schematic diagram showing various types of signal to interference ratios in a method for controlling a transmission power of a UE of a user equipment according to the present invention. As shown in FIG. 1, an SIR _ar get _Add is an additional target signal to interference ratio that satisfies the initial channel quality of the service. SIRtarget _BlCT is the target signal to interference ratio that needs to be met to meet the business error block rate (BLER) requirement. SIRtarget is the actual target signal to interference ratio. The method for controlling the transmission power of the UE will be described below with reference to FIG. 1, in which the following technical points are involved:

101：将目标信干比分成两部分组成，即实际目标信干比为： SIRtarget=SIRtarget_BlCT + SIRt_arget_Add。其中，一部分是基于业务目标质量（QoS ) 所需的目标信干比 ( SIRtargetBier) ,另一部分主要用于满足业务初始阶段更高的业务质量要求所额外增加的量（ SIRtarget_Add)。 101: The target signal-to-interference ratio is divided into two parts, that is, the actual target signal-to-interference ratio is: SIRtarget=SIRtarget _BlCT + SIRt _ar get _Add . Among them, part is based on the target signal-to-interference ratio (SIRtargetBier) required for the quality of service (QoS), and the other part is mainly used to meet the additional amount of service quality requirements in the initial stage of the service (SIRtarget _Add ).

102：满足业务质量（Qos)要求需达到的目标信干比 8¾^1¾₆½^采用传统的外环功控（OLPC) 算法得到，可基于业务质量（比如误块率（BLER)、 DPCCH信道的误比特率（BER) 或者误帧率（FER)、传输块和误块数的关系）进行调整。 103：为满足业务初始阶段更高质量需求而额外增加的目标信干比 SIRtarget_Add可采用周期触发或者事件触发的方式进行等步长或者变步长的方式进行下调，直到 SIRtargetAdd小于一定的取值门限或者业务质量高于某一水平后停止下调 SIRtarg_et_Add。 104：在 103中，所述事件方式指可以基于 SIRtraget的另一分量 SIRtarget_BlCT的下调触发 SIRtarget_Add下调。 102: The target signal-to-interference ratio required to meet the quality of service (Qos) requirement is 83⁄4^13⁄4 ₆ 1⁄2^ using the traditional outer loop power control (OLPC) algorithm, which can be based on the quality of service (such as block error rate (BLER), DPCCH channel). The bit error rate (BER) or frame error rate (FER), the relationship between the transport block and the number of error blocks are adjusted. 103: The target signal to be added to meet the higher quality requirements in the initial stage of the service than the SIRtarget _Add can be adjusted in a step-by-step or variable-step manner by means of a periodic trigger or an event trigger until the SIRtargetAdd is less than a certain value. Stop the SIRtarg _e t _Add after the threshold or service quality is above a certain level. 104: In 103, the event mode refers to a SIRtarget _Add down-regulation that can be triggered based on a down-modulation of another component SIRtarget _{BlCT of the SIRtraget} .

105：在 103中，下调动作采用变步长方式时是指可以基于 SIRt_arget_Add的大小或者业务质量的不同获取不同的调整步长。原则是： SIRt_arg_et_Add越大或者业务质量越好，则 SIRtarget_Add下调步长越大。 105: In 103, when the down-modulation action adopts the variable step size mode, it means that different adjustment step sizes can be obtained based on the size of the SIRt _ar get _Add or the quality of service. The principle is: The larger the SIRt _ar g _e t _Add or the better the quality of the service, the larger the SIRtarget _Add down step.

In a preferred embodiment, when the quality of service depends on the block error rate BLER, the SIRtarget _BlCT adjustment further includes: comparing the statistical BLER and the BLER target value within a predetermined time window; if the statistical BLER > For the BLER target value, SIRtarg _e t _BlCT is raised to a predetermined step size, and vice versa. The embodiment of the present invention can be specifically implemented by the following method: 201: The target signal-to-interference ratio is divided into two parts, that is, the actual target signal-to-interference ratio is:

SIRtarget=SIRtarget_Bier + SIRtarget_Add 其中， SIRtarget_BlCT 的初始值为 InitSIRtarget_BlCT， SIRtarget_Add 的初始值为 InitSIRtargetAdd ，贝¹ J SIRtraget 的初始值为 InitSIRtarget=InitSIRtarget_Bler + InitSIRtargetAdd° 202：满足业务质量（Qos)要求需达到的目标信干比 SIRtarget_BlCT采用传统的 OLPC 算法得到，可基于业务的 BLER/BER/FER统计得到，比如 BLER高于一个门限时上调 SIRtarget_BlCT，当 BLER低于一个门限时下调 SIRtarget_BlCT。 SIRtarget=SIRtarget _B ier + SIRtarget _Add where SIRtarget _{BlCT has} an initial value of InitSIRtarget _BlCT , SIRtarget _Ad d has an initial value of InitSIRtargetAdd , and Bay ¹ J SIRtraget has an initial value of InitSIRtarget=InitSIRtarget _Bler + InitSIRtargetAdd° 202: The target signal-to-interference ratio required to meet the quality of service (Qos) requirement is _obtained by the traditional OLPC algorithm, which can be obtained based on the BLER/BER/FER statistics of the service. For example, if the BLER is higher than a threshold, the SIRtarget _{BlCT is} raised, when the BLER is Lower SIRtarget _BlCT below a threshold.

203：为满足业务初始阶段更高质量需求而额外增加的目标信干比 SIRtarge dd可采用周期触发或者事件触发的方式进行等步长或者变步长的方式进行下调，直到 SIRtarget_Add小于或等于一定的取值门限或者业务质量高于或等于某一水平后停止下调 SIRtarget_Add。 203: The additional target signal-to-interference ratio SIRtarge dd can be adjusted in a step-by-step or variable-step manner by means of periodic triggering or event triggering, in order to meet the higher quality requirements in the initial stage of the service, until the SIRtarget _{Add is} less than or equal to a certain value. SIRtarget _{Add is} stopped after the value threshold or service quality is higher than or equal to a certain level.

204：在 203中，如果采用事件触发方式，则可在 81¾ ₆½₆₁下调时，同时下调 SIRtarget_Add。 205：在 203中，采用等步长调整方案时，步长可固定设置为 Step, BP : 204: In 203, if event trigger mode is used, SIRtarget _Add can be lowered at the same time when 813⁄4 ₆ 1⁄2 _{61 is} down. 205: In 203, when the equal step adjustment scheme is adopted, the step size can be fixedly set to Step, BP:

SIRtarget_Add (n+l)= SIRtarget_Add (n)-step; 其中， SIRtarget_Add (n)为当前 SIRtarget_Add， SIRtarget_Add (n+1)为调整后的 SIRtarget_Add。 SIRtarget _A dd (n+l)= SIRtarget _Add (n)-step; where SIRtarget _Add (n) is the current SIRtarget _Add and SIRtarget _Add (n+1) is the adjusted SIRtarget _Add .

206：在 203中，采用可变步长调整方案时，可依据 SIRt_arg_et_Add 的大小或者业务质量（比如在当前误块率（BLER)、DPCCH信道的误比特率（BER)或者误帧率（FER)) 划分 SIRt_arg_et_Add不同下调步长的阶段，各阶段对应的 SIRta_rget_Add下调步长关系为 Step(l)>=Step(2)>=...>=Step(m-l)>= Step(m)。即： 206: In 203, when the variable step size adjustment scheme is adopted, the size or quality of service of the SIRt _ar g _e t _Add may be used (such as the current block error rate (BLER), the bit error rate (BER) of the DPCCH channel, or an error. Frame rate (FER)) SIRt _ar g _e t _Add the stage of different down-steps. The SIRta _r get _Add step-down relationship for each stage is Step(l)>=Step(2)>=...>= Step(ml)>= Step(m). which is:

If (阶段 1 ) SIRtargetAdd (n+l)= SIRtarget_Add (n)-step(l); If (stage 1) SIRtargetAdd (n+l)= SIRtarget _Add (n)-step(l);

Elseif (阶段 2) Elseif (stage 2)

SIRtargetAdd (n+l)= SIRtarget_Add (n)-step(2); SIRtargetAdd (n+l)= SIRtarget _Add (n)-step(2);

Elseif (阶段 m-1 ) ： SIRtargetAdd (n+ 1 )= SIRtarget_Add (n)-step(m- 1 ); Elseif (stage m-1): SIRtargetAdd (n+ 1 )= SIRtarget _Add (n)-step(m-1);

Else SlRtargetAdd (n+l)= SlRtargetAdd (n)-step(m); 其中， SIRtarget_Add (n)为当前 SIRtarget_Add， SIRtarget_Add (n+l)为调整后的 SIRtarget_Add。 Else SlRtargetAdd (n+l)= SlRtargetAdd (n)-step(m); where SIRtarget _Add (n) is the current SIRtarget _Add and SIRtarget _Add (n+l) is the adjusted SIRtarget _Add .

207：在 206中，在基于 SIRt_arg_et_Add的大小划分调整步长阶段时，如果划分为 m 个阶段，则设置各阶段的门限为 T(l)>=T(2)>=...>=T(m-l)即：阶段 1 : SIRtargetAdd > T(1); 阶段 2: T(2)<SIRtarget_Add<= T(l); 207: In 206, when the step size is adjusted according to the size division of SIRt _ar g _e t _Add , if it is divided into m stages, the threshold of each stage is set to T(l)>=T(2)>=. ..>=T(ml) ie: Phase 1: SIRtargetAdd >T(1); Phase 2: T(2)<SIRtarget _A dd<= T(l);

阶段 m- 1： T(m- 1 )<SIRtarget_Add <= T(m-2); 阶段 m_: SIRtargetAdd <= T(m-l) 。 Stage m- 1: T(m-1) <SIRtarget _A dd <= T(m-2); Stage m _: SIRtargetAdd <= T(ml).

208: 在 206中，在基于业务质量（BLER/BER/FER) 划分调整步长阶段时，如果划分为 m个阶段，同样需要设置 m-1个门限，以 BLER/BER/FER为例，则各阶段的门限关系为 T(l)<=T(2)<=...<=T(m-l)， BP : 阶段 1 : BLER (或者 BER、 FER) < T(1); 阶段 2: T(l) <= BLER (或者 BER、 FER) < T(2); 208: In 206, when the step size is adjusted based on the quality of service (BLER/BER/FER), if it is divided into m stages, it is also necessary to set m-1 thresholds, for example, BLER/BER/FER. The threshold relationship at each stage is T(l)<=T(2)<=...<=T(ml), BP: Stage 1: BLER (or BER, FER) < T(1); Stage 2: T (l) <= BLER (or BER, FER) < T(2);

阶段 m-1 : T(m-2) <= BLER (或者 BER、 FER) < T(m-l); 阶段 m: BLER (或者 BER、 FER) >= T(m-l) 。 Stage m-1 : T(m-2) <= BLER (or BER, FER) < T(m-l); Stage m: BLER (or BER, FER) >= T(m-l).

209：在 203中，如果基于 SIRtarget_Add的大小判断是否停止下调 SIRtarget_Add，则当 SIRtarget_Add等于或者小于固定配置的门限（ SirTarget Additional ) 之后停止 SIRtarget_Add的调整。 209: In 203, if the size is determined based on whether SIRtarget _Add SIRtarget _Add stop down, when the SIRtarget _Add equal to or less than a threshold (SirTarget Additional) fixedly arranged stop adjusting the SIRtarget _Add.

210：在 203 中，如果基于业务质量判断是否停止下调 SIRt_arg_et_Add，则可以在当前误块率（BLER)、 DPCCH信道的误比特率（BER)或者误帧率（FER)等于或者大于 (BlerThreshold或 BerThreshold或 FerTheshold)之后，停止 SIRtarget_Add降低。图 3 显示了本发明一种用户设备 UE的发射功率控制装置的示意图，如图 3所示，包括：目标信干比获取模块 301，设置为根据业务质量目标确定并调整目标信干比；测量信干比获取模块 302，设置为通过测量当前接收信号质量得到测量信干比； UE发射功率调整模块 303，设置为按照所述测量信干比逼近所述目标信干比的方式，调整 UE的发射功率，使调整后的发射功率与所述目标信干比相适应。其中，所述目标信干比获取模块包括：第一目标信干比单元，设置为获得满足稳定状态下目标业务质量要求的第一目标信干比 SIRt_arget_BlCT; 第二目标信干比单元，设置为获得为满足初始阶段业务质量要求而额外增加的第二目标信干比 SIRtarg_et_Add。具体地说，所述 SIRtarg_et_BlCT通过外环功率控制 OLPC算法得到，并基于业务质量进行调整；所述 SIRtarge dd是预设值，并在周期触发或事件触发下按照等步长或变步长调整方式进行调整。其中所述业务质量取决于误块率 BLER或者 DPCCH信道的误比特率 BER或者误帧率 FER，并且与 BLER、 BER或者 FER成反比。下面结合图 4至图 11具体对本发明所述技术方案的实施作进一步的详细描述。实施例一：周期触发、等步长调整，基于 SIRtarge dd的大小停止下调。业务目标信干比为 SIRtarget=SIRtarget_BlCT + SIRtarget_Add，其中， SIRtarget_Bler用于保证业务稳定阶段的目标质量，由传统外环功控算法（OLPC ) 基于业务目标 BLER 得到； SIRt_arg_et_Add主要用于满足业务初始阶段较高的业务质量要求。预置条件：将 SIRtarget_Add下调到等于或低于门限 SirTarget Additional之后停止调整。令 SirTargetAdditional=OdB，即最终是将 SIRtarget收敛到 SIRtarget_Bler。 SIRtargetBier和 SIRtarget_Add分别进行调整。其中, 811 1_¾^_1¾的调整方法是：根据每个 TTI中的误块计算 SIRtarget单步调整量，此调整量根据调度周期内的正确块数、误块数、总块数和 BLER目标值得到，计算公式如下：
