为使本发明的目的、技术方案和优点更加清楚明白,下文中将结合附图对本发明的实施例进行详细说明。需要说明的是,在不冲突的情况下,本申请中的实施例及实施例中的特征可以相互任意组合。
图1为本发明实施例的信道质量指示信息的调整方法的流程图,如图1所示,本发明实施例的信道质量指示信息的调整方法包括以下步骤:
步骤101,获取信道的第一质量参数,判断所述第一质量参数是否大于第一设定阈值。
本发明实施例中,第一质量参数可以是误块率。第一设定阈值可以是根据各不同的运营商网络对UE的误块率的最低要求值。不同的运营商设置的值均不同。但对于具体的运营商而言,该第一设定阈值是确定的,这里不再赘述。
即当前的信道的误块率大于运营商要求的误块率时,需要对相关上报参数进行调整。当前的信道的误块率小于运营商要求的误块率时,说明其满足运营商要求。当前的信道的误块率大于运营商要求的误块率时,执行步骤102。
步骤102,将所述第一质量参数对应的第二参数的调整量减去第一调整步长。
本步骤中,第二质量参数是指信道的信噪比,该第二质量参数与第一质量参数具有相关性。当确定当前的误块率超出第一设定阈值时,说明当
前的信道条件较差,需要对当前信道的信噪比调整参数进行相应调整,以使网络侧选用的编码方式与当前的信道条件相适配。
步骤103,获取第二参数,将所述第二质量参数与所述调整量进行累加,作为调整后的第二质量参数。
本步骤即对当前信道的信噪比进行调整,以通过调整当前的信噪比来确定调整后的CQI。
步骤104,根据调整后的第二质量参数确定第三质量参数,并上报所述第三质量参数。
根据信噪比与CQI的对应关系,通过调整后的信噪比确定出CQI,以向网络侧上报所确定的CQI。
本发明实施例中,当步骤101中确定出所述第一质量参数小于第一设定阈值时,直接对信噪比进行下述方式的调整:
重新获取信道的第一质量参数;
判断重新获取的第一质量参数是否小于或者等于第二设定阈值,小于或者等于第二设定阈值时将所述调整量与第二调整步长累加;所述第二调整步长小于所述第一调整步长;
判断重新获取的第一质量参数是否大于或者等于第三设定阈值,大于或者等于第三设定阈值时将所述调整量减去第三调整步长;所述第三调整步长小于所述第一调整步长;
重新获取第二质量参数,将重新获取的第二质量参数与所述调整量进行累加,作为调整后的第二质量参数;
根据调整后的第二质量参数确定第三质量参数,并上报所述第三质量参数。
本发明实施例中,将所述第二质量参数的调整量与第二调整步长累加,包括:
获取所述第一质量参数中的第一子参数和第二子参数;
确定所述第一子参数大于所述第二子参数时,计算所述第一子参数与所述第二子参数之间的差值,根据所述差值的大小确定所述第二调整步长的大小;
将所述第二质量参数的调整量与所述第二调整步长累加。
本发明实施例中,所述将所述第二质量参数的调整量减去第三调整步长,包括:
获取所述第一质量参数中的第一子参数和第二子参数;
确定所述第一子参数小于所述第二子参数时,计算所述第二子参数与所述第一子参数之间的差值,根据所述差值的大小确定第三调整步长的大小;
将所述第二质量参数的调整量减去第三调整步长。
本发明实施例中,当执行步骤104之后,所述方法还包括:
判断调整后的信道的第一质量参数小于第一设定阈值时,重新获取信道的第一质量参数,以所述第二调整步长或所述第三调整步长调整所述调整量;
判断调整后的信道的第一质量参数大于或者等于第一设定阈值时,重新获取信道的第一质量参数,并重新判断所述第一质量参数是否大于或者等于第一设定阈值。
以下通过具体示例,进一步阐明本发明实施例的技术方案的实质。
本发明实施例中,将与信道质量指示关联的直接调整对象确定为解调后的信噪比(SNR,Signal-to-Noise Ratio)估计值;
SNR估计值的调整范围和最小颗粒度,均可以精细设定与调整;
SNR调整过程包括两个阶段:粗调整阶段和精调整阶段;
通过SNR估计值与CQI上报值的映射关系,实现了CQI的精细调整,
保证链路自适应技术所依赖的信道质量指示信息更加及时与准确。
本发明实施例以WCDMA和TD-SCDMA系统为例,如图2所示,本发明实施例的信道质量指示信息的调整方法主要包含两个调整阶段:
SNR粗调整阶段:通过高速下行共享信道(HS-DSCH,High Speed Downlink Shared Channel)获取首传新数据的误块率(BLER,Block Error Rate)大于某个预先设定的性能门限(该门限由运营商网络设定)时,SNR估计值需要进行大步长的粗调整,以使得BLER值迅速收敛到预先设定的性能门限以内,进入SNR精调整阶段;
SNR精调整阶段:根据HS-DSCH首传新数据的正确接收结果(ACK,Acknowledge)和错误接收结果(NACK,Non-Acknowledge)的分布情况,对BLER值进行实时更新,并且根据BLER值确定作为“SNR-to-CQI”映射表查询入口的信噪比是否需要调整以及相应的调整方向与步长。
假设HS-DSCH信道解调后的信噪比估计值为SNRest,作为“SNR-to-CQI”映射表查询入口的信噪比为SNRmap,“SNR-to-CQI”映射表的查询输出结果为CQI上报值CQIrep,则SNR粗调整阶段和精调整阶段的相关过程具体描述如下:
SNR粗调整阶段包括以下步骤:
步骤1:设置SNR粗调整阶段的BLER统计周期,HS-DSCH首传新数据的NACK计数器为NACK_CNT;SNRest下调所对应的误块率门限为BLER_STAGE1,SNRest的修正量为ΔSNR,调整步长为stepsNR_Stagel;
步骤2:在一个BLER统计周期内,如果NACK_CNT≥BLER_STAGE1,则SNRest对应下调,修正量ΔSNR=ΔSNR-stepSNR_Stagel;
步骤3:根据SNRest与SNRmap之间的转换公式,得到“SNR-to-CQI”映射表查询入口的信噪比:SNRmap=SNRest+ΔSNR;
步骤4:查询“SNR-to-CQI”映射表,得到CQI上报值CQIrep;
步骤5:如果NACK_CNT≥BLER_STAGE1,则复位NACK_CNT计数器,并重启SNR粗调整过程,直至满足NACK_CNT<BLER_STAGE1为止,进入SNR精调整阶段。
在SNR精调整阶段,假设修正量ΔSNR的向上调整步长和向下调整步长分别为stepSNR_UP和stepSNR_DOWN;一方面,通过对于HS-DSCH首传新数据BLER的实时刷新,以决定修正量ΔSNR是否需要调整以及相应的调整方向;另一方面,通过对于HS-DSCH首传新数据ACK/NACK的连续性判断,以决定修正量ΔSNR调整步长的取值;具体包括以下步骤:
步骤1:假设SNR粗调整阶段得到的、收敛于预先设定的性能门限以内的BLER值为BLERini,作为SNR精调整阶段BLER刷新操作的初始值;BLER刷新操作采用无限冲激响应(IIR,Infinite Impulse Response)滤波器(本发明实施例中不限于此)实现,滤波因子为alphaBLER,取值范围为[0,1],当前获取的HS-DSCH首传数据的ACK/NACK值所占的权重为(1-alphaBLER);IIR滤波器的输出为BLER_CUR;
步骤2:假设SNRest上调所对应的误块率门限设置为:BLER_SNR_UP,SNRest下调所对应的误块率门限设置为:BLER_SNR_DOWN,则修正量ΔSNR调整方向的判断方法为:
if(BLER_CUR≤BLER_SNR_UP)
ΔSNR=ΔSNR+stepSNR_UP
else if(BLER_CUR≥BLER_SNR_DOWN)
ΔSNR=ΔSNR-stepsNR_DOWN
else
ΔSNR保持不变;
步骤3:BLER的实时滤波结果,决定SNRest修正量ΔSNR是否需要调整以及相应的调整方向;同时,设置一个长度为N的滑动窗口,动态刷新并记录最近N次得到的HS-DSCH首传新数据的ACK和NACK分布情况;
步骤4:假设滑动窗口中的ACK个数为KACK,NACK个数为KNACK,如果“KACK-KNACK>0”且差值的取值范围为{1,2,...,M+},则设定与差值取值范围一一对应的M+个SNR上调步长{step1,SNR_UP,step2,SNR_UP,...,stepM+,SNR_UP},根据实际差值的大小确定对应的SNR上调步长:
if(KACK-KNACK==k)//1≤k≤M+
ΔSNR=ΔSNR+stepk,SNR_UP
如果“KNACK-KACK>0”且差值的取值范围为{1,2,...,M-},则设定与差值取值范围一一对应的M-个SNR下调步长{step1,SNR_DOWN,step2,SNR_DOWN,...,stepM-,SNR_DOWN},根据实际差值的大小确定对应的SNR下调步长:
if(KNACK-KACK==k)//1≤k≤M-
ΔSNR=ΔSNR-stepk,SNR_DOWN
步骤5:对更新后的修正量ΔSNR取值范围进行必要的限定,避免出现SNR过度调整的情况,即:ΔSNR,min≤ΔSNR≤ΔSNR,max,其中,ΔSNR,min和ΔSNR,max分别为预先设定的修正量ΔSNR的取值下限和取值上限;
步骤6:根据SNRest与SNRmap之间的转换公式,得到“SNR-to-CQI”映射表查询入口的信噪比:SNRmap=SNRest+ΔSNR;
步骤7:查询“SNR-to-CQI”映射表,得到CQI上报值CQIrep。
