基于前述无线通信系统100、用户设备200以及网络设备300分别对应的实施例，本申请实施例提供了一种参数调整方法。
请参见图4A，图4A为本申请实施例提供的一种参数调整方法的流程示意图，包括以下步骤：
步骤401：用户设备的PDCP实体发送一指示；用户设备的MAC实体接收来自用户设备的PDCP实体的所述指示，所述指示用于指示用户设备的MAC实体调整数据承载所对应的逻辑信道的参数。
步骤402：用户设备的MAC实体调整所述数据承载所对应的逻辑信道的参数。
在本申请的一实施例中，上述参数调整方法应用于双连接(Dual connectivity，DC)。
在本申请的一实施例中，上述数据承载为分叉承载(split bearer)。
在本申请的一实施例中，用户设备的MAC实体执行逻辑信道优先级(Logical Channel Prioritization，LCP)过程。
DC技术的主要思想是将经过非理想回程链路(backhaul)相连的不同演进型基站(evolved Node B，eNB)的载波进行聚合，以提高数据传输速率。
在DC中，一个用户设备将同时连接两个eNB，一个是主基站(Master eNB，MeNB)，另一个是辅基站(Secondary eNB，SeNB)，MeNB和SeNB之间通过非理想的backhaul连接。
在DC下，MeNB和SeNB的协议栈如图4B所示，对于数据无线承载(Dada Radio Bearer，DBR)1，仅仅通过MeNB向用户设备发送。对于DBR2，一部分通过MeNB向用户设备发送，另一部分通过X2接口首先发送给SeNB，然后SeNB向用户设备发送。具体地，MeNB将该DBR2的一部分数据包以PDCP PDU的数据包形式首先发给SeNB，然后经过SeNB发送给用户设备。进一步，为了提升上行数据传输速率，对于DBR2的上行传输，用户设备可以将部分PDCP数据包向MeNB发送，同时将部分PDCP数据包向SeNB发送。由于上述DBR2的数据被分叉成两部分分别通过不同的eNB进行传输，所以这个DBR2成为分叉承载。
在DC中，一个用户设备会配置两个小区组(Cell group，CG)，一个是主小区组(Master Cell group，MCG)，另一个是辅小区组(Secondary Cell group，SCG)。
MCG是指与MeNB相关联的一个小区组，由主小区(Primary Cell，PCell)以及零个或多个辅小区(Secondary Cell，SCell)构成。
SCG是指与SeNB相关联的一个小区组，由主的辅小区(Primary Secondary Cell，PSCell)以及零个或多个辅小区(Secondary Cell，SCell)构成。
其中，PCell是指用户设备建立RRC连接的小区，PCell提供安全相关的参数以及配置有物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源。PSCell是指在辅小区组内配置有PUCCH的辅小区。除了PCell和PSCell外，MCG和SCG内的SCell都不配置PUCCH资源。PUCCH信道主要用于传输混合自动重传请求确认信息(HARQ-ACK)、信道状态信息(Channel State Information，CSI)和调度请求(Scheduling Request，SR)等信息。
对于一个用户设备而言，可能同时存在多个业务，或多个DRB需要进行传输，则在MAC实体用户设备需要根据eNB分配的上行资源，将多个DRB的数据进行复用后传输。每个DRB对应一个逻辑信道并配置一个逻辑信道优先级。将多个DRB的数据进行复用传输的过程称为LCP过程。
在现有的LCP过程执行当中，RRC实体通过控制以下几个参数来对MAC调度进行控制，这些参数包括逻辑信道优先级、优先级比特率(priority Bit Rate，PBR)以及持续时间参量(Bucket Size Duration，BSD)。那么上述逻辑信道的参数包括以下至少一种：逻辑信道优先级、PBR以及BSD。
在本申请的一实施例中，上述MAC实体为预配置的主primary RLC实体对应的MAC实体。
举例来说，如图4C所示，DRB2为分叉承载，用户设备有两个RLC实体和两个MAC实体，假如MeNB所对应的RLC实体预配置为primary RLC实体，SeNB所对应的RLC实体预配置为Secondary RLC实体，那么primary RLC对应的MAC实体为primary MAC实体(即MeNB所对应的MAC实体)，Secondary RLC对应的MAC实体为Secondary MAC实体(即SeNB所对应的MAC实体)。
在本申请的一实施例中，上述指示为用户设备的实体间交互指示。其中，实体间交互指示是一个层间监护的indication，体现在协议里在MAC层，可能是“upon reception of indication from upper layers”。
在本申请的一实施例中，所述方法还包括：
在PDCP PDU的数量和RLC PDU的数量的总和小于所述数据承载所配置的门限值的情况下，所述用户设备的PDCP实体发送所述指示。
具体地，由于分叉承载有时候可以仅仅通过一个eNB进行上行数据传输，而有时候，当该分叉承载的数据量比较大的时候，需要同时通过两个eNB进行上行数据传输。
举例来说，如图4C所示，DRB2为分叉承载，假如用户设备的PDCP PDU的数量和用户设备的RLC PDU的数量的总和小于DRB2所配置的门限值时，表示DRB2的数据量比较小，此时用户设备仅通过一个eNB进行上行数据传输，假如用户设备仅通过MeNB进行上行数据传输。由于相对于通过两个eNB进行上行数据传输而言，仅通过一个eNB进行上行数据传输的传输效率较慢，为了保证在仅通过一个eNB进行上行数据传输的情况下，不影响数据传输效率，需要调整DRB2的MeNB所在的逻辑信道的参数。
在本申请的一实施例中，用户设备的MAC实体调整所述数据承载所对应的逻辑信道的参数的具体实现方式有：
用户设备的MAC实体将所述数据承载所对应的逻辑信道的优先级比特率PBR值从第一数值调整至第二数值；
其中，所述第二数值＝所述第一数值*n，所述第一数值为所述逻辑信道原始配置的PBR值，所述n为大于1的整数，所述逻辑信道为所述primary RLC实体所在的逻辑信道。

请参见图4D，图4D为本申请实施例提供的一种参数调整方法的流程示意图，包括以下步骤：
步骤501：用户设备的MAC实体执行LCP过程。
其中，所述MAC实体为预配置的primary RLC实体对应的MAC实体。
步骤502：在用户设备的MAC实体执行LCP过程中，用户设备的PDCP发送一指示。
其中，所述指示用于指示用户设备的MAC实体调整数据承载所对应的逻辑信道的参数，所述数据承载为分叉承载。
步骤503：用户设备的MAC实体接收来自用户设备的PDCP的所述指示；用户设备的MAC实体将所述数据承载所对应的逻辑信道的PBR值从第一数值调整至第二数值。
其中，所述第二数值＝所述第一数值*n，所述第一数值为所述逻辑信道原始配置的PBR值，所述n为大于1的整数，所述逻辑信道为所述primary RLC实体所在的逻辑信道。
举例来说，如图4C所示，DRB2为分叉承载，用户设备有两个RLC实体和两个MAC实体，这两个RLC实体有primary RLC实体和Secondary RLC实体，这两个MAC实体有primary MAC实体和Secondary MAC实体，DRB2对应两个逻辑信道，这两个逻辑信道有primary RLC实体和primary MAC实体所在的逻辑信道1和Secondary RLC实体和Secondary MAC实体所在的逻辑信道2。
在primary MAC实体执行LCP过程中，如果primary MAC实体接收来自PDCP实体发送一指示，该指示用于指示调整DRB2所对应的逻辑信道的参数。由于该指示是PDCP实体在PDCP PDU的数量和RLC PDU的数量的总和小于DRB2所配置的门限值的情况下发送的，此时用户设备仅通过MeNB进行上行数据传输，即用户设备仅使用DRB2对应的逻辑信道1进行上行数据传输。假设第一值＝a，n＝2，那么primary MAC实体在接收到PDCP实体发送该指示后，primary MAC实体将DRB2对应的逻辑信道1的PBR值从a调整至a*2。
在本申请的一实施例中，所述数据承载所对应的逻辑信道包括第一逻辑信道和第二逻辑信道，所述第一逻辑信道为所述primary RLC实体所在的逻辑信道；用户设备的MAC实体调整所述数据承载所对应的逻辑信道的参数的具体实现方式有：
所述用户设备的MAC实体将所述第一逻辑信道的PBR值从第一数值调整至第三数值；
其中，所述第三数值＝所述第一数值+所述第二逻辑信道原始配置的PBR值，所述第一数值为所述第一逻辑信道原始配置的PBR值。
实施例2：
请参见图4E，图4E为本申请实施例提供的一种参数调整方法的流程示意图，包括以下步骤：
步骤601：用户设备的MAC实体执行LCP过程，所述MAC实体为预配置的primary RLC实体对应的MAC实体。
步骤602：在用户设备的MAC实体执行LCP过程中，用户设备的PDCP发送一指示。
其中，所述指示用于指示用户设备的MAC实体调整数据承载所对应的逻辑信道的参数，所述数据承载为分叉承载。
其中，所述数据承载所对应的逻辑信道包括第一逻辑信道和第二逻辑信道，所述第一逻辑信道为所述primary RLC实体所在的逻辑信道，所述第二逻辑信道为所述Secondary RLC实体所在的逻辑信道。
步骤603：用户设备的MAC实体接收来自用户设备的PDCP的所述指示；用户设备的MAC实体将所述第一逻辑信道的PBR值从第一数值调整至第三数值。
其中，所述第三数值＝所述第一数值+所述第二逻辑信道原始配置的PBR值，所述第一数值为所述第一逻辑信道原始配置的PBR值。
举例来说，如图4C所示，DRB2为分叉承载，用户设备有两个RLC实体和两个MAC实体，这两个RLC实体有primary RLC实体和Secondary RLC实体，这两个MAC实体有primary MAC实体和Secondary MAC实体，DRB2对应两个逻辑信道，这两个逻辑信道有primary RLC实体和primary MAC实体所在的逻辑信道1和Secondary RLC实体和Secondary MAC实体所在的逻辑信道2。
在primary MAC实体执行LCP过程中，如果primary MAC实体接收来自PDCP实体发送一指示，该指示用于指示调整DRB2所对应的逻辑信道的参数。由于该指示是PDCP实体在PDCP PDU的数量和RLC PDU的数量的总和小于DRB2所配置的门限值的情况下发送的，此时用户设备仅通过MeNB进行上行数据传输，即用户设备仅使用DRB2对应的逻辑信道1进行上行数据传输。假设第一值＝a，DRB2对应的逻辑信道1原始配置的PBR值＝b，那么primary MAC实体在接收到PDCP实体发送该指示后，primary MAC实体将DRB2对应的逻辑信道1的PBR值从a调整至a+b。
在本申请的一实施例中，用户设备的MAC实体调整所述数据承载所对应的逻辑信道的参数的具体实现方式有：
用户设备的MAC实体将所述数据承载所对应的逻辑信道的PBR值从第一数值调整至第四数值；
所述第一数值为所述逻辑信道原始配置的PBR值，所述第四数值为网络设备为所述逻辑信道配置的PBR值，所述第四数值大于所述第一数值，所述逻辑信道为所述primary RLC实体所在的逻辑信道。
实施例3：
请参见图4F，图4F为本申请实施例提供的一种参数调整方法的流程示意图，包括以 下步骤：
步骤701：用户设备的MAC实体执行LCP过程，所述MAC实体为预配置的primary RLC实体对应的MAC实体。
步骤702：在用户设备的MAC实体执行LCP过程中，用户设备的PDCP发送一指示。
其中，所述指示用于指示用户设备的MAC实体调整数据承载所对应的逻辑信道的参数，所述数据承载为分叉承载。
步骤703：用户设备的MAC实体接收来自用户设备的PDCP的所述指示；用户设备的MAC实体将所述数据承载所对应的逻辑信道的PBR值从第一数值调整至第四数值。
其中，所述第一数值为所述逻辑信道原始配置的PBR值，所述第四数值为网络设备为所述逻辑信道配置的PBR值，所述第四数值大于所述第一数值，所述逻辑信道为所述primary RLC实体所在的逻辑信道。
举例来说，如图4C所示，DRB2为分叉承载，用户设备有两个RLC实体和两个MAC实体，这两个RLC实体有primary RLC实体和Secondary RLC实体，这两个MAC实体有primary MAC实体和Secondary MAC实体，DRB2对应两个逻辑信道，这两个逻辑信道有primary RLC实体和primary MAC实体所在的逻辑信道1和Secondary RLC实体和Secondary MAC实体所在的逻辑信道2。
在primary MAC实体执行LCP过程中，如果primary MAC实体接收来自PDCP实体发送一指示，该指示用于指示调整DRB2所对应的逻辑信道的参数。由于该指示是PDCP实体在PDCP PDU的数量和RLC PDU的数量的总和小于DRB2所配置的门限值的情况下发送的，此时用户设备仅通过MeNB进行上行数据传输，即用户设备仅使用DRB2对应的逻辑信道1进行上行数据传输。假设第一值＝a，第四数值＝c，c＞a，那么primary MAC实体在接收到PDCP实体发送该指示后，primary MAC实体将DRB2对应的逻辑信道1的PBR值从a调整至c。
可见，本申请中，首先，用户设备的MAC实体接收用户设备的PDCP实体发送的一指示，该指示用于指示MAC实体调整数据承载对应的逻辑信道的参数；然后用户设备的MAC实体调整数据承载对应的逻辑信道的参数。这样可实现MAC实体灵活调整逻辑信道的参数，进而达到灵活调整数据传输效率的目的。
