技术领域
本申请实施例涉及信号处理领域，特别涉及一种自适应调制编码方法、装置、电子设备及存储介质。
背景技术
自适应调制编码(Adaptive Modulation Control，AMC)，是应用于通信传输的处理技术，包括内环(inner-loop)和外环(outer-loop)处理过程，对于下行AMC内环是指基站根据终端上报的信道状态信息确定该终端对应下行信号的调制编码方式(Modulation And Coding Scheme，MCS)，对于上行AMC，内环是指基站根据对接收信号的测量来确定该终端对应上行信号的MCS；外环则是指基站根据真实调度的反馈结果(解对ACK/解错NACK)及目标误块率(Block Error Ratio，BLER)值来更新外环值，内环+外环值最终决定终端的调度MCS，外环的目的是将信号传输的实际BLER维持在目标BLER附近。
然而，目前无线通信中，由于基站硬件、终端、或者特定时隙Slot上存在干扰等问题，会存在不同时隙间的解调能力差异很大的现象，传统的AMC方案所有时隙共用一套AMC机制，这样对于某些解调能力较弱的时隙会出高BLER现象，而对于其它正常时隙而言，会出现BLER偏低的现象，最终影响系统整体的吞吐量。

本申请的一个实施方式涉及一种自适应调制编码方法。具体流程如图1所示。
步骤101，周期性统计各时隙对应的误块率BLER；
步骤102，根据统计的BLER筛选出异常时隙和正常时隙，其中，正常时 隙为BLER位于预设的门限区间内的时隙，异常时隙为BLER位于门限区间外的时隙；
步骤103，为异常时隙单独维护一套不同于正常时隙的AMC逻辑，其中，正常时隙共用同一套AMC逻辑，AMC逻辑用于获取时隙的外环调制编码方式MCS值，外环调制编码方式MCS值用于对时隙进行自适应调制编码；
步骤104，在周期结束时，检测异常时隙的BLER是否收敛至门限区间内，并更新BLER收敛至门限区间内的异常时隙的自适应调制编码的调整量值。
本实施例中，通过在线统计各时隙对应的BLER指标，周期性的将异常时隙进行识别，并对异常时隙另外进行AMC逻辑学习，待异常时隙另外的AMC逻辑学习收敛后，更新异常时隙对应的AMC调整量值，并将该异常时隙与其它正常时隙放在一起进行公共AMC逻辑的维护。对于异常时隙通过自适应调制编码的调整量值来保障其在公共AMC机制中的初始调度MCS等于另外AMC机制中的收敛MCS值，从而保证整个系统的吞吐量。
下面对本实施方式的自适应调制编码方法的实现细节进行具体的说明，以下内容仅为方便理解提供的实现细节，并非实施本方案的必须。
在步骤101中，周期性统计各时隙对应的误块率BLER；即，统计当前实际情况中时隙的BLER，使得能够针对当前的时隙配置进行适应性的优化调整。
在一个例子中，周期性统计各时隙对应的误块率BLER，例如：实时统计第一窗口内的各时隙分别对应的调度解错次数以及调度总次数；根据时隙的调度解错次数与调度总次数，获取时隙对应的BLER。
例如，实时统计第一窗长(WindowTime-Thr1)及第二窗长(WindowTime-Thr2)内各时隙对应的BLER值，可以采用截窗方式统计，在窗长末端统计出各时隙对应的BLER值，当新的窗到来时要将BLER清空重新统计新窗对应的BLER值。其中，各时隙可以属于不同的用户终端。计算一个窗长时间内的BLER对应的值，例如通过以下公式：
Figure PCTCN2022106594-appb-000001
在一个例子中，根据时隙的调度解错次数与调度总次数，获取时隙对应的BLER之前，还包括：检测调度总次数是否大于预设阈值；若调度总次数大于 预设阈值，则再执行根据时隙的调度解错次数与调度总次数，获取时隙对应的BLER。即，对于分母(调度总次数)小于预设阈值的BLER值，认为是非可靠BLER，该时隙将被当做正常时隙对待。另外，预设阈值是支持自定义配置的。
在一个例子中，在周期结束时，检测异常时隙的BLER是否收敛至门限区间内，例如：统计在第一窗口结束之前的第二窗口内的异常时隙对应的调度解错次数以及调度总次数；根据异常时隙对应的调度解错次数与调度总次数，获取异常时隙对应的BLER；检测获取的所述异常时隙对应的BLER是否收敛至所述门限区间内；其中，第二窗口的窗长小于第一窗口的窗长。可以知道的是，窗长即为该窗口的时长，且第二窗口的起止时间均不超过第一窗口的起止时间，第一窗口与第二窗口的关系如图2所示。
本步骤中通过筛选一定条件下的时隙，作为对当前状况进行适应性优化调整的基础。
在步骤102中，根据统计的BLER筛选出异常时隙和正常时隙，其中，正常时隙为BLER位于预设的门限区间内的时隙，异常时隙为BLER位于门限区间外的时隙；
在一个例子中，定义异常时隙对应高BLER门限(BLER_H_Thr)，异常时隙对应低BLER门限(BLER_L_Thr)，当第一窗长内统计的时隙对应BLER大于高门限(BLER_H_Thr)或者小于低门限(BLER_L_Thr)时，将把该时隙当做异常时隙。若第一窗长内统计的所有时隙对应的BLER均大于高门限(BLER_H_Thr)或者均小于低门限(BLER_L_Thr)时，将不进行异常时隙的筛选，也就是把所有时隙都当做正常时隙进行处理。高于高门限则意味着误块率过高，需要进行调整；低于低门限时，传输速率偏保守，也需要进行调整。
在步骤103中，为异常时隙单独维护一套不同于正常时隙的AMC逻辑，其中，正常时隙共用同一套AMC逻辑，AMC逻辑用于获取时隙的外环调制编码方式MCS值，外环调制编码方式MCS值用于对时隙进行自适应调制编码。
在一个例子中，为各异常时隙分别独立维护一套不同于正常时隙的AMC逻辑，不同的异常时隙对应的AMC逻辑不相同。例如，系统共维护n+1套AMC逻辑，其中n为异常时隙个数，1代表非异常时隙对应的AMC逻辑，即非异常 的时隙对应的公共AMC逻辑。待本周期第一窗长(WindowTime-Thr1)结束时，若存在异常时隙,在接下来的另一个第一窗长(WindowTime-Thr1)内将对每个异常时隙各自维护一套AMC逻辑，进而得到各时隙对应的Slot级外环(外环MCS4Slot_id)；同时对于所有非异常时隙维护一套公共外环(外环MCS4Comn时隙)。若不存在异常时隙,在接下来的另一个第一窗长(WindowTime-Thr1)内,只需对所有时隙维护一套公共外环(外环MCS4ComnSlot)。以达到对系统进行针对性维护的目的，保证系统的吞吐量。
在另一个例子中，包括，对异常时隙进行分组；为同一组的异常时隙维护同一套不同于正常时隙的AMC逻辑，不同组的异常时隙对应的AMC逻辑不相同。也就是说，在检测到异常时隙的时候，对各异常时隙进行分组处理，各组采用不同的AMC逻辑，相较于一些实施方式仍能够进一步保证系统的吞吐量，并且相较于上述实施例能够减少需要维护的AMC逻辑。例如，根据异常时隙的异常程度对各异常时隙划分不同的异常等级，每个等级作为一个异常时隙组，存在一套需要维护的AMC逻辑。减少需要维护的AMC逻辑的同时也能保证系统的吞吐量。
在步骤104中，在周期结束时，检测异常时隙的BLER是否收敛至门限区间内，并更新BLER收敛至门限区间内的异常时隙的自适应调制编码的调整量值。
在一个例子中，将周期结束时异常时隙的外环MCS值与所述周期结束时所述异常时隙所对应的AMC调整量值求和，得到和值，将所述和值与所述正常时隙的外环MCS值作差，得到更新后的所述BLER收敛至所述门限区间内的所述异常时隙的自适应调制编码的调整量值。
例如：系统初始化各时隙对应的AMC调整量(AMC_Ajust4Slot)为0，系统的调度MCS＝内环MCS+外环MCS4Slot+AMC_Ajust4Slot。待本周期的第一窗长(WindowTime-Thr1)结束时，判断上一周期内是否筛选出异常时隙,或本周期内是否存在另外维护的AMC逻辑，若存在，则进行如下操作：
首先判断当前周期内另外维护的AMC逻辑，在本周期结束时是否收敛：统计第一窗长(WindowTime-Thr1)结束之前的第二窗长(WindowTime-Thr2)内该时隙对应的BLER是否趋于收敛BLER区间，其中收敛BLER区间为 [BLER_Thr1，BLER_Thr2]，若第二窗长内该时隙对应的BLER趋于区间[BLER_Thr1，BLER_Thr2]内，即对应的BLER值位于区间[BLER_Thr1，BLER_Thr2]内，则该时隙对应的AMC已收敛；否则该时隙对应的BLER不收敛。其中第一窗长与第二窗长的关系见图2。
若收敛，则对当前周期正在处理的异常时隙Slot_id采取如下操作：更新该时隙对应的AMC调整量(AMC_Ajust4Slot_id)：
AMC_Ajust4Slot_id新＝外环MCS4Slot_id+AMC_Ajust4Slot_id-外环MCS4ComnSlot；其中，外环MCS4Slot_id为当前周期维护的异常时隙对应的AMC在本周期第一窗长(WindowTime-Thr1)结束时对应的收敛外环值。外环MCS4ComnSlot代表：非异常时隙共同维护的AMC在本周期第一窗长(WindowTime-Thr1)结束时对应的外环值。AMC_Ajust4Slot_id代表：该异常时隙在单独维护AMC逻辑时使用的旧AMC调整量值。在接下来的新周期的第一窗长内，将该异常时隙放入正常时隙队列，与其它正常时隙共同维护一套AMC逻辑，所有正常时隙对应的ACK/NACK(调度解对/调度解错)数据共同维护一套公共外环(外环MCS4ComnSlot)。
若不收敛，则对当前周期正在处理的异常时隙Slot_id采取如下操作：在新周期的第一窗长内，该异常时隙继续保留保持另外AMC维护逻辑，不更新其对应AMC调整量值(AMC_Ajust4Slot_id)，不将其放入正常时隙队列。待下一个周期的第一窗长(WindowTime-Thr1)结束时，再重复上述流程。
使得各时隙能够调度与其性能相匹配的MCS，改善部分时隙对应BLER过高或过低的问题，进而使系统的吞吐量得到改善。
为了便于理解，以下以一个下行AMC过程中的示例性实施过程进行说明，可以理解的是，该实施方式也能够应用于上行AMC过程中，本申请不对其相关的应用过程进行限制：
首先，参数变量设置：第一窗长WindowTime-Thr1：2s；第二窗长WindowTime-Thr2：1s；高BLER门限：BLER_H_Thr：30％；低BLER门限：BLER_L_Thr：2％；收敛BLER区间为[BLER_Thr1，BLER_Thr2]，BLER_Thr1:8％；BLER_Thr2：15％；总调度次数的预设阈值N：50。采用T-NR制式，5ms单周期配置，时隙配比为[D D D D D D D D U U D D D D D D D D U U],下行AMC 逻辑,当然该申请同样适用于上行AMC逻辑。其中D代表down，表示下行时隙，U代表up，表示上行时隙。
Step0:统计量。
BLER4WindowTime1_1＝[1％，2％，40％，8％，9％，10％，8％，8％，8％，8％，10％，8％，8％，8％，10％，10％]；
BLER4WindowTime1_2＝[5％,10％，10％，8％，9％，10％，8％，8％，8％，8％，10％，8％，8％，8％，10％，50％]；
BLER4WindowTime2_2＝[3％,10％]；
N1_1＝[200，40，200，200，200，200，190，192，199，200，200，200，200，200，200，200]；
N1_2＝[200，200，200，200，200，200，190，192，199，200，200，200，200，200，200，200]；
n1_2＝[200,200]；外环MCS4Slot_0_2＝13；外环MCS4Slot_2_2＝-3；外环MCS4ComnSlot_2＝7。其中：BLER4WindowTime1_1：代表第一个周期，第一窗长(WindowTime-Thr1)内，各下行时隙对应的BLER值；BLER4WindowTime1_2：代表第二个周期，第一窗长(WindowTime-Thr1)内，各下行时隙对应的BLER值；BLER4WindowTime2_2：代表第二个周期，第二窗长(WindowTime-Thr2)内，异常时隙(该异常时隙由统计量BLER4WindowTime1_1确定)对应的BLER值；N1_1：代表第一个周期，第一窗长(WindowTime-Thr1)内，各下行时隙对应的调度次数；N1_2：代表第二个周期，第一窗长(WindowTime-Thr1)内，各下行时隙对应的调度次数；n1_2：代表第二个周期，第二窗长(WindowTime-Thr2)内，各异常时隙对应的调度次数；外环MCS4Slot_0_2：代表第二个周期，第一窗长(WindowTime-Thr1)结束时，异常Slot0维护的外环值；外环MCS4Slot_2_2：代表第二个周期，第一窗长(WindowTime-Thr1)结束时，异常Slot2维护的外环值；外环MCS4ComnSlot_2：代表第二个周期，第一窗长(WindowTime-Thr1)结束时，所有有正常时隙共同维护的外环值。
Step1:周期性统计各时隙对应的BLER。第一个周期，调度第一窗长(WindowTime-Thr1)内，各下行时隙对应的BLER为[1％，2％，40％，8％， 9％，10％，8％，8％，8％，8％，10％，8％，8％，8％，10％，10％]；各下行时隙对应的调度次数为：[200，40，200，200，200，200，190，192，199，200，200，200，200，200，200，200]；T-NR，5ms单周期配置下，下行时隙共16个，其对应Slot_id分别为0,1,2,3,4,5,6,7,10,11,12,13,14,15,16,17。
Step2:异常时隙筛选。由Step1的统计可知；Slot0,1,2对应的BLER异常，但是由于Slot1对应的调度次数未满足门限值N(50)，认为Slot1对应的BLER统计不可靠，所以最终的异常时隙为时隙0和时隙2。
Step3:对于异常时隙单独进行AMC逻辑维护。在接下来的第二个周期，第一窗长(WindowTime-Thr1)内系统将维护2+1套AMC逻辑，其中2套分别维护异常Slot0和异常Slot2，另外一套维护所有的非异常时隙。进而得到Slot0及Slot2对应的时隙级外环(外环MCS4Slot_0，外环MCS4Slot_2),及所有非异常时隙共同理维护一套公共外环(外环MCS4ComnSlot)。
Step4:更新异常时隙对应的AMC调整量。由于第一个周期内，未进行异常时隙的AMC逻辑维护，所以在第一个周期第一窗长结束时，未对异常时隙对应的AMC调整量进行更新。在第二个周期第一窗长结束时，更新异常时隙对应的AMC调整量；AMC_Ajust4Slot_id新＝外环MCS4Slot_id+AMC_Ajust4Slot_id-外环MCS4ComnSlot；所以：AMC_Ajust4Slot_0新＝13+0-7＝6；AMC_Ajust4Slot_2新＝-3+0-7＝-10；系统内每个时隙对应的调度MCS为：MCS_Slot_id＝内环MCS+外环MCS4Slot_id+AMC_Ajust4Slot_id。同时，在第二个周期第一窗长结束时，根据各时隙统计的BLER信息筛选新的异常时隙，重复上述操作。
Step5:周期性统计各时隙对应的BLER。第二个周期，调度第一窗长(WindowTime-Thr1)内，各下行时隙对应的BLER为：[5％,10％，10％，8％，9％，10％，8％，8％，8％，8％，10％，8％，8％，8％，10％，50％]；各下行时隙对应的调度次数为：[200，200，200，200，200，200，190，192，199，200，200，200，200，200，200，200]；T-NR，5ms单周期配置下，下行时隙共16个，其对应Slot_id分别为0,1,2,3,4,5,6,7,10,11,12,13,14,15,16,17。
Step6:异常时隙筛选。由Step5的统计可知,此刻不存在异常时隙,所以在第三个周期内无需维护异常时隙对应的AMC逻辑，在第三个周期结束时也无需 更新AMC调整量，只需维护正常时隙对应的公共AMC逻辑即可。
如图3至图5所示，上述功能关闭时，Slot2对应的BLER较高，功能开启后，Slot2的BLER得到有效控制，并且整体流量提升4.6％，当然，流量增益的大小与异常时隙的个数及对应BLER的异常程度强相关。其中，图3为功能开关流量及其他指标对比，图4为功能关各时隙对应BLER，图5为功能开各时隙对应BLER。
在第三个周期结束时，需要根据各时隙新的BLER统计值，继续筛选异常时隙，并重复上述步骤。
上面各种方法的步骤划分，只是为了描述清楚，实现时可以合并为一个步骤或者对某些步骤进行拆分，分解为多个步骤，只要包括相同的逻辑关系，都在本专利的保护范围内；对算法中或者流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其算法和流程的核心设计都在该专利的保护范围内。
在本实施方式中，通过在线统计各时隙对应的BLER指标，周期性的将异常时隙进行识别，并对异常时隙另外进行AMC逻辑学习，待异常时隙另外的AMC逻辑学习收敛后，更新异常时隙对应的AMC调整量值，并将该异常时隙与其它正常时隙放在一起进行公共AMC逻辑的维护。对于异常时隙通过自适应调制编码的调整量值来保障其在公共AMC机制中的初始调度MCS等于另外AMC机制中的收敛MCS值，从而保证整个系统的吞吐量。即，能够解决部分时隙对应BLER偏低或偏高的现象，保证系统整体的吞吐量。

  7. 根据权利要求5或6所述的自适应调制编码方法，其中，所述在周期结束时，检测所述异常时隙的BLER是否收敛至所述门限区间内，包括：
    统计在所述第一窗口结束之前的第二窗口内的所述异常时隙对应的调度解错次数以及调度总次数；
    根据所述异常时隙对应的所述调度解错次数与所述调度总次数，获取所述异常时隙对应的BLER；
    检测获取的所述异常时隙对应的BLER是否收敛至所述门限区间内；
    其中，所述第二窗口的窗长小于所述第一窗口的窗长。
  8. 一种自适应调制编码装置，包括：
    统计模块，用于周期性统计各时隙对应的误块率BLER；
    筛选模块，用于根据统计的所述BLER筛选出异常时隙和正常时隙，其中，所述正常时隙为BLER位于预设的门限区间内的时隙，所述异常时隙为BLER 位于所述门限区间外的时隙；
    自适应调制编码模块，用于为所述异常时隙单独维护一套不同于所述正常时隙的AMC逻辑，其中，所述正常时隙共用同一套AMC逻辑，所述AMC逻辑用于获取时隙的外环调制编码方式MCS值，所述外环调制编码方式MCS值用于对时隙进行自适应调制编码；
    检测模块，用于在周期结束时，检测所述异常时隙的BLER是否收敛至所述门限区间内；
    更新模块，用于更新BLER收敛至所述门限区间内的所述异常时隙的自适应调制编码的调整量值。
  9. 一种电子设备，包括：
    至少一个处理器；以及，
    与所述至少一个处理器通信连接的存储器；其中，
    所述存储器存储有可被所述至少一个处理器执行的指令，所述指令被所述至少一个处理器执行，以使所述至少一个处理器能够执行如权利要求1至7中任一项所述的自适应调制编码方法。
  10. 一种计算机可读存储介质，存储有计算机程序，所述计算机程序被处理器执行时实现权利要求1至7中任一项所述的自适应调制编码方法。
