具体实施方式
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合附图对本申请的各实施例进行详细的阐述。然而，本领域的普通技术人员可以理解，在本申请各实施例中，为了使读者更好地理解本申请而提出了许多技术细节。但是，即使没有这些技术细节和基于以下各实施例的种种变化和修改，也可以实现本申请所要求保护的技术方案。以下各个实施例的划分是为了描述方便，不应对本申请的具体实现方式构成任何限定，各个实施例在不矛盾的前提下可以相互结合相互引用。
本申请的提升语音业务下行质量的方法适用于4G、5G和6G网络，可以实现VoLTE语音或VoNR语音在下行弱覆盖场景、或者下行受到强干扰场景下，通过对目标用户设备语音业务的PDSCH(Physical Downlink Shared channel，物理下行共享信道)加功率，和/或，对目标用户设备语音业务的PDCCH(Physical Downlink Control channel，物理下行控制信道)加功率，以此来显著改善语音下行通话质量。
本申请的实施例涉及一种提升语音业务下行质量的方法，如图1所示，包括：
步骤101，响应于第一指令，判断目标用户设备UE所在小区的物理下行共享信道PDSCH是否存在剩余功率，目标UE为正在处理语音业务的UE。
在本实施例中，语音业务为4G网络、5G网络或6G网络中的语音业务。剩余功率可以是整个下行可用功率，也可以是语音业务对应的下行可用功率。当然，如果小区开启了功率共享，剩余功率还包括其他小区共享的可用功率。另外，PDSCH为LTE物理下行信道中的一种，是LTE承载主要用户数据的下行链路通道，所有的用户数据都可以使用。
在一实施例中，在步骤101之前，还包括：检测目标UE语音业务的PDSCH的当前误块率，在PDSCH的当前误块率高于第一目标误块率且目标UE的调制与编码策略MCS值为预设的MCS下限值的情况下，生成第一指令。
需要说明的是，误块率指的是出错的块在所有发送的块中所占的百分比，比如，在LTE中数据信道的误块率要求为10％。另外，LTE中速率的配置可以通过MCS(Modulation and Coding Scheme，调制与编码策略)索引值实现，MCS将所关注的影响通讯速率的因素作为表的列，将MCS索引作为行，形成一张速率表。所以，每一个MCS索引其实对应了一组参数下的物理传输速率。本实施例中提到的MCS值即为MCS索引值。另外，本申请提供的提升语音业务下行质量的方法只针对QPSK调制方式或比QPSK更加低阶的调制方式，而在速率表中每个MCS索引值有对应的调制方式，因此，预设的MCS下限值可以据此设置。
在另一实施例中，在PDSCH的当前误块率高于第一目标误块率且所述目标UE的MCS值为MCS下限值的情况下，且在生成所述第一指令之前，还包括：更新第一目标误块率，其中，更新后的第一目标误块率高于更新前的第一目标误块率；重新检测目标UE的PDSCH的当前误块率，且重新检测的PDSCH的当前误块率高于更新后的所述第一目标误块率。
可以理解的是，在目标UE语音业务的PDSCH的误块率高于第一目标误块率且目标UE的调制与编码策略MCS值为预设的MCS下限值的时，本申请进一步提高第一目标误块率，即更新第一目标误块率使得更新后的第一目标误块率高于更新前的第一目标误块率，也就是说，通过此步骤提高了对业务传输中出错的块的容忍度，即允许语音质量轻度下降。在更新第一目标误块率后，再次检测目标UE的PDSCH的当前误块率，当重新检测的PDSCH的当前误块率高于更新后的第一目标误块率时，触发生成第一指令进行加功率操作，提升语音下行性能。
步骤102，若目标UE所在小区的PDSCH存在剩余功率，基于剩余功率为目标UE语音业务的PDSCH加功率。
在一实施例中，步骤102具体为，基于剩余功率和预设的第一加功率步长为目标UE语音业务的PDSCH加功率。在基于剩余功率和预设的第一加功率步长为目标UE语音业务的PDSCH加功率之后，重新检测PDSCH的当前误块率；且在重新检测的PDSCH当前误块率高于更新后的第一目标误块率的情况下，生成第一指令。比如：第一加功率步长设置为1db，即每次加1db的功率。
在一实施例中，步骤102具体为：若目标UE所在小区的PDSCH存在剩余功率且目标UE语音业务的PDSCH的当前功率尚未达到目标UE语音业务的PDSCH的参考功率，基于剩余功率和参考功率为目标UE语音业务的PDSCH加功率。
需要说明的是，每个UE语音业务的PDSCH都有一个参考功率，该参考功率表征该UE语音业务的PDSCH的加功率上限，一旦UE语音业务的PDSCH的功率超过参考功率，就不 能进行加功率操作，具体可以根据应用场景和业务需求自行定义设置。
步骤103，若目标UE所在小区的PDSCH不存在剩余功率，减小目标UE语音业务的PDSCH占用资源块的数量，并基于减少的资源块所占的功率为目标UE语音业务的PDSCH加功率。
在一实施例中，减小目标UE语音业务的PDSCH占用资源块的数量，包括以下方式的其中之一或任意组合：若目标UE的非连续接收DRX功能处于开启状态，关闭目标UE的DRX功能；若目标UE的下行编码速率尚未达到预设的速率下限值，降低目标UE的下行编码速率；若目标UE的下行语音包尚未被分片，对下行语音包进行分片。
具体地说，当DRX(Discontinuous Reception，非连续接收)功能处于开启状态时，消耗的资源块数量可能会翻倍，影响加功率的效果。比如：当DRX功能关闭时，可能每20ms调度1个VoLTE语音包，当DRX功能开启时，则变为每40ms调度2个VoLTE语音包，消耗翻倍的资源块。另外，对目标UE的下行编码速率进行降速处理，可以更好的发挥加功率的效果，尤其是针对小带宽场景。比如：可以设定速率下限值为AMR-WB6.6K，若此时下行编码速率为AMR-WB23.85K，还未达到速率下限值，则此时可以降低目标UE的下行编码速率，具体地，可以降速为AMR-WB12.65K，也可以直接降为速率下限值AMR-WB6.6K。当然，此处仅为具体的举例说明，具体速率下限值的设定以及降速的步长可以根据应用场景和质量提升要求进行调整。另外，对语音包进行分片指把一个VoLTE语音包分片，使得每个分片占用更少的资源块RB，进一步提升PDSCH加功率的效果。在一实施方式中，建议最多分成2片。值得注意的是，对语音包进行分片主要应用于小带宽场景。
需要说明的是，减小目标UE语音业务的PDSCH占用资源块的数量的可选方式为：若目标UE的DRX功能处于开启状态，则关闭所述目标UE的DRX功能；若目标UE的DRX功能处于关闭状态且目标UE的下行编码速率尚未达到预设的速率下限值，则降低目标UE的下行编码速率；若目标UE的DRX功能处于关闭状态、目标UE的下行编码速率已达到速率下限值且下行语音包尚未被分片，则对下行语音包进行分片。
在一实施例中，步骤103具体为：基于减少的资源块所占的功率和第一加功率步长为目标UE语音业务的PDSCH加功率。在为目标UE语音业务的PDSCH加功率后，需要重新检测PDSCH的当前误块率；且在重新检测的PDSCH当前误块率高于更新后的第一目标误块率的情况下，生成第一指令。
另外，为了进一步保障加功率的效果，本申请还包括：响应于第一指令，向小区的邻小区发送暂停使用目标时频资源的请求；其中，目标时频资源是指目标UE语音业务当前使用的时频资源。如此，通过暂停目标UE所在小区的邻小区使用目标时频资源，可以充分保障目标UE语音业务的下行质量得到改善。
本申请提出的一种提升语音业务下行质量的方法，当目标用户设备UE所在小区的物理下行共享信道PDSCH存在剩余功率时，基于剩余功率为PDSCH加功率，当不存在剩余功率时，通过减小目标UE语音业务的PDSCH占用资源块的数量为PDSCH加功率，如此通过加功率的方法可以显著改善语音业务下行质量。
本申请的实施例涉及一种提升语音业务下行质量的方法，如图2所示，包括：
步骤201，响应于第一指令，判断目标用户设备UE所在小区的物理下行共享信道PDSCH是否存在剩余功率，目标UE为正在处理语音业务的UE。
步骤202，若目标UE所在小区的PDSCH存在剩余功率，基于剩余功率为所述目标UE语音业务的PDSCH加功率。
步骤203，若目标UE所在小区的PDSCH不存在剩余功率，减小目标UE语音业务的PDSCH占用资源块的数量，并基于减少的资源块所占的功率为目标UE语音业务的PDSCH加功率。
本实施例中，步骤201-步骤203与步骤101-步骤103的具体实施细节基本相同，在此不做赘述。
步骤204，响应于第二指令，根据为目标UE语音业务的PDSCH加功率的方式，确定为目标UE的PDSCH降功率的方式。
在一实施例中，在步骤204之前，还包括：重新检测目标UE语音业务的PDSCH的当前误块率，在重新检测的PDSCH的当前误块率低于预设的第一目标误块率的情况下，生成第二指令。
可以理解的是，在每次对目标UE语音业务的PDSCH进行加功率后都需要重新检测目标UE语音业务的PDSCH的当前误块率，一旦当前误块率低于预设的第一目标误块率，则表明当前的语音业务下行质量较好，已经得到改善，基于此生产第二指令，触发降功率操作。而对目标UE语音业务的PDSCH进行降功率的方法是根据对目标UE语音业务的PDSCH加功率方法控制操作。需要注意的是，此时的第一目标误块率可以是更新后的第一目标误块率。
步骤205，根据确定的降功率的方式为目标UE语音业务的PDSCH降功率，其中，为所述目标UE语音业务的PDSCH加功率的方式为：基于所述剩余功率为所述目标UE语音业务的PDSCH加功率，或者，减小所述目标UE语音业务的PDSCH占用资源块的数量，并基于减少的资源块所占的功率为目标UE语音业务的PDSCH加功率。
在本实施例中，步骤205具体为：根据确定的降功率的方式和预设的第一降功率步长为目标UE语音业务的PDSCH降功率。在为目标UE语音业务的PDSCH降功率之后，需要重新检测UE语音业务的PDSCH的当前误块率；且在重新检测的PDSCH的当前误块率低于预设的第一目标误块率的情况下，生成第二指令。
需要注意的是，与加功率的过程类似，在进行降功率时，每次对目标UE语音业务的PDSCH进行降功率后，都需要重新检测UE语音业务的PDSCH的当前误块率。若当前的误块率高于预设的第一目标误块率，表明此时下行语音业务质量较差，则进行加功率操作，若当前的误块率低于预设的第一目标误块率，表明此时下行语音业务质量得到改善，则进行降功率操作。当然，此时的第一目标误块率可以是更新后的第一目标误块率。
在一实施例中，确定为目标UE语音业务的PDSCH降功率的方式，包括以下方式的其中之一或任意组合：若目标UE的下行语音包已被分片，则对下行语音包分片进行合并；目标UE的下行编码速率尚未达到预设的速率上限值，则提高目标UE的下行编码速率；若目标UE的DRX功能处于关闭状态，则开启目标UE的DRX功能。
具体地说，对语音包分片进行合并、提高下行编码速率、开启DRX功能都与加功率过程中的关闭DRX功能、降低下行编码速率、对语音包进行分片等操作为反向控制的操作。
需要说明的是，确定为目标UE语音业务的PDSCH降功率的可选方式为：若目标UE的下行语音包已被分片，则对下行语音包分片进行合并；若目标UE的下行语音包未被分片且目标UE的下行编码速率尚未达到速率上限值，则提高目标UE的下行编码速率；若目标UE 的下行语音包未被分片、目标UE的下行编码速率已达到速率上限值且目标UE的DRX功能处于关闭状态，则开启目标UE的DRX功能。
本申请提出的一种提升语音业务下行质量的方法，当目标用户设备UE所在小区的物理下行共享信道PDSCH存在剩余功率时，基于剩余功率为PDSCH加功率，当不存在剩余功率时，通过减小目标UE语音业务的PDSCH占用资源块的数量为PDSCH加功率，如此通过加功率的方法可以显著改善语音业务下行质量。而当语音业务下行质量得到改善时，又根据目标UE语音业务的PDSCH加功率的方式，反方向地对PDSCH降功率，如此，可以使得目标UE所在小区的PDSCH的剩余功率得到充分利用，避免功率的浪费。
本申请的实施例涉及一种提升语音业务下行质量的方法，如图3所示，包括：
步骤301，响应于第三指令，判断目标UE所在小区的物理下行控制信道PDCCH是否存在剩余功率，目标UE为正在处理语音业务的UE。
本实施例中主要针对PDCCH上的语音业务质量进行提升。
在一实施例中，步骤301之前，还包括：检测目标UE语音业务的PDCCH的当前误块率，在PDCCH的当前误块率高于第二目标误块率且目标UE语音业务的CCE聚合度为预设的聚合度上限值的情况下，生成第三指令。
需要说明的是，CCE(Control Channel Element，控制信道元)是构成PDCCH的基本单元，PDCCH中CCE的个数称为聚合度。在发送PDCCH时，可根据实际的无线信道环境来决定采用多少聚合度发送控制信息，当无线信道环境比较恶劣时，采用大的聚合度可以获得较为良好的解调性能；在无线信道环境比较好时，采用较小的聚合度。本实施例中，预设的聚合度上限值可以根据应用场景、网络状况和业务需求等自行定义设置。比如：对于VoLTE，可以设置聚合度上限值为8，对于VoNR，可以设置聚合度上限值为16。当PDCCH的当前误块率高于第二目标误块率且目标UE语音业务的CCE聚合度为预设的聚合度上限值时，说明此时语音业务质量较差，需要生成第三指令触发加功率操作。
步骤302，若目标UE所在小区的PDCCH存在剩余功率，基于剩余功率为目标UE语音业务的PDCCH加功率。
在本实施例中，步骤302具体为：基于剩余功率和预设的第二加功率步长为目标UE语音业务的PDCCH加功率。每次为目标UE语音业务的PDCCH加功率后，需要重新检测PDCCH的当前误块率；且在重新检测的PDCCH的当前误块率高于预设的第二目标误块率的情况下，生成第三指令。需要说明的是，本实施例中的剩余功率可以是整个下行可用功率，也可以是语音业务的下行可用功率。另外，第二加功率步长可以自行调整设置。
在一实施例中，步骤302之后，还包括：响应于第四指令，对目标UE语音业务的PDCCH降功率。另外，响应于第四指令，对目标UE语音业务的PDCCH降功率具体为：响应于第四指令，并基于预设的第二降功率步长为目标UE语音业务的PDCCH降功率。每次为目标UE语音业务的PDCCH降功率后，都需要重新检测UE语音业务的PDCCH的当前误块率；且在重新检测的PDCCH的当前误块率低于预设的第二目标误块率的情况下，生成第四指令。
可以理解的是，每次进行加功率操作或进行降功率操作后，都需要重新检测目标UE语音业务的PDCCH的当前误块率，根据当前误块率和第二目标误块率确定需要执行的操作。
本申请提出的一种提升语音业务下行质量的方法，基于目标UE所在小区的物理下行控制信道PDCCH的剩余功率为PDCCH进行加功率，可以显著改善语音业务下行质量。
本申请的实施例涉及一种提升语音业务下行质量的方法，包括：基于上述实施例所述的提升语音业务下行质量的方法，对目标UE语音业务的PDSCH加功率；和/或，基于上述实施例所述的提升语音业务下行质量的方法，对目标UE语音业务的PDCCH加功率。
若在同一调度周期中，目标UE语音业务的PDSCH的当前功率与目标UE语音业务的PDCCH的当前功率之后超过目标UE语音业务的下行功率阈值，将目标UE语音业务的控制信令放到下一调度周期发送。其中，在目标UE语音业务的PDSCH被加功率的情况下，PDSCH的当前功率为加功率后的功率；在目标UE语音业务的PDCCH被加功率的情况下，PDCCH的当前功率为加功率后的功率。
需要说明的是，对目标UE语音业务的PDSCH加功率的方法与步骤101至步骤103、步骤201至步骤205的基本相同，在此不作赘述，对目标UE语音业务的PDCCH加功率的方法与步骤301至步骤302基本相同，在此不做赘述。
本领域技术人员可以理解的是，PDSCH主要承载用户数据，PDCCH主要承载控制信令，当在同一TTI(Transport Time Interval，传输时间间隔)对PDSCH上的用户数据和PDCCH上的控制信令进行调度时，若此时目标UE语音业务的PDSCH的当前功率与所述目标UE语音业务的PDCCH的当前功率之和超过了目标UE语音业务的下行功率阈值，则将目标UE语音业务的控制信令放到下一调度周期发送。如此，可以充分保障语音业务的下行质量。
本申请提出的一种提升语音业务下行质量的方法，通过对目标UE语音业务的PDSCH加功率，以及对目标UE语音业务的PDCCH加功率，可以显著改善语音业务下行质量。当在同一TTI对PDCCH和PDCCH进行调度且功率不足时，将目标UE语音业务的控制信令放到下一调度周期发送，优先保障了语音业务的下行质量。
此外，应当理解的是，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，都在本申请的保护范围内；对流程中添加无关紧要的修改或者引入无关紧要的设计，但不改变其流程的核心设计都在该申请的保护范围内。

其中，所述存储模块402存储有可被所述处理模块401执行的指令，所述指令被所述至少一处理模块401执行，以使所述至少一处理模块401能够执行上述实施例所述的提升语音业务下行质量的方法。
