Description

上行数据传输方法、装置及计算机存储介质 技术领域
本公开涉及通信技术，尤其涉及一种上行数据传输方法、装置及计算机存储介质。
背景技术
终端的电磁辐射会对人体安全产生影响，特别是随着第5代移动通信技术(5th generation mobile networks或5th generation wireless systems，简称5G)的即将商用，支持高频段高功率的终端将成为市场上的主流，而这也客观上增加了终端的电磁辐射对人体安全的风险。
终端的人体安全的电磁辐射标准，国际上采用电磁波吸收比值(Specific Absorption Rate，SAR)和最大可允许的暴露量(Maximum Permissible Exposure，MPE)来表示，SAR主要针对的是低频段，而MPE主要针对的是毫米波频段。
相关技术中，为了降低终端发射对人体安全产生的影响，通常采用在发射功率的基础上进行一定的功率回退或者减少终端发射的上行占空比(Duty Cycle)来达到满足SAR或MPE的要求。然而，在毫米波频段由于波束较窄，辐射比较集中，一旦该波束朝向人体，为了满足MPE要求最大可能需要20dB的功率的回退，这么大的功率降低可能会造成严重的上行覆盖不足，甚至会造成通信链路的突然失效。

请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。
其中，终端11可以是指向用户提供语音和/或数据连通性的设备。终端11可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，终端11可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remote terminal)、接入终端(access terminal)、用户装置(user terminal)、用户代理(user agent)、用户设备(user device)、或用户终端(User Equipment，UE)。或者，终端11也可以是无人飞行器的设备。或者，终端11也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线通信设备。或者，终端11也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(New Radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，机器类型通信(Machine-Type Communication，MTC)系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基 站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(Central Unit，CU)和至少两个分布单元(Distributed Unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。
在一些实施例中，终端11之间还可以建立E2E(End to End，端到端)连接。比如车联网通信(Vehicle to Everything，V2X)中的V2V(Vehicle to Vehicle，车对车)通信、V2I(Vehicle to Infrastructure，车对路边设备)通信和V2P(Vehicle to Pedestrian，车对人)通信等场景。
在一些实施例中，上述无线通信系统还可以包含网络管理设备13。
若干个基站12分别与网络管理设备13相连。其中，网络管理设备13可以是无线通信系统中的核心网设备，比如，该网络管理设备13可以是演进的数据分组核心网(Evolved Packet Core，EPC)中的移动性管理实体(Mobility Management Entity，MME)。或者，该网络管理设备也可以是其它的核心网设备，比如服务网关(Serving Gate Way，SGW)、公用数据网网关(Public Data Network Gate Way，PGW)、策略与计费规则功能单元(Policy and Charging Rules Function，PCRF)或者归属签约用户网络侧设备(Home Subscriber Server，HSS)等。对于网络管理设备13的实现形态，本公开实施例不做限定。
终端的人体安全的电磁辐射标准，国际上采用电磁波吸收比值(Specific Absorption Rate，SAR)和最大可允许的暴露量(Maximum Permissible Exposure，MPE)来表示，SAR主要针对的是低频段，而MPE主要针对的是毫米波频段。
相关技术中，为了降低终端发射对人体安全产生的影响，通常采用在发射功率的基础上进行一定的功率回退或者减少终端发射的上行占空比(Duty Cycle)来达到满足SAR或MPE的要求。比如：在3GPP TS38.101-2射频标准中，专门引入了最大允许的终端功率回退(Maximum allowed UE output power reduction，简称P-MPR)，需要终端上报最大上行占空比能力(Maximum Duty Cycle Capability)，当调度的上行占空比大于该最大上行占空比时，终端降低发射等级或者降低发射功率。上述方法对于满足低频SAR的要求非常有效。然而，在毫米波频段由于波束较窄，辐射比较集中，一旦该波束朝向人体，为了满足MPE要求，最大可能需要20dB的功率回退，降低这么大的功率可能会造成严重的上行覆盖不足，甚至会造成通信链路的突然失效。
基于上述无线通信系统，为了解决现有支持毫米波频段的UE为满足MPE要求需要较大的功率回退，从而造成严重的上行覆盖不足，甚至会造成通信链路的失效的问题，提出本公开方法各个实施例。

在已有的PHR上报的格式基础上增加P-MPR信息的上报，P-MPR信息的另一种上报格式如图4所示，在图4中，前两行是现有的方法，具体可参见TS38.321。在图4中，最后一行是新增加的P-MPR信息，具体地，P-MPR值占8个比特(bit)位，其中R作为保留位(reserved bit)，其余比特位作为P-MPR值的上报，比如，P-MPR值用5位比特表示，PHR消息中P-MPR值与实际值的映射关系如表2所示。

表2
UE在某次通信中，根据传感器和使用场景确定波束需要的P-MPR值，如P-MPR值＝6dB。UE将该P-MPR值在PHR值上报时一起上报给基站。以0.5dB为粒度，P-MPR值＝6dB为例，若在P-MPR信息上报格式中P-MPR值为6位比特，则P-MPR值＝6dB可对应表1中的P-MPR_12，比特位表示如图5所示，即P-MPR值＝6dB表示为001100。以1dB为粒度，P-MPR值＝6dB上报，若在P-MPR信息上报格式中P-MPR值为5位比特，则P-MPR值＝6dB可对应于表2中的P-MPR_6，比特位表示如图6所示，即P-MPR值＝6dB表示为00110。
UE在某次通信中，根据业务类型和使用场景确定波束需要的P-MPR值，如P-MPR＝6dB。UE根据调度的波形以及资源块(Resource Block，RB)的起始位置和数量，以及额外的NS要求，确定max(MPR f,c，A-MPR f,c)+ΔMB P,n，如果max(MPR f,c，A-MPR f,c)+ΔMB P,n＝9dB，预设触发条件P-MPR>max(MPR f,c，A-MPR f,c)+ΔMB P,n，可知，P-MPR值无需上报，因此PHR上报时可不包含P-MPR值。如果max(MPR f,c，A-MPR f,c)+ΔMB P,n＝4dB，则根据预设触发条件确定P-MPR值需要上报，且需要上报的值是P-MPR值＝6dB，如果以0.5dB为粒度，具体上报格式可如图5所示。如果1dB为粒度，具体格式可如图6所示。
UE在某次通信中，根据业务类型和使用的场景确定波束需要的P-MPR值＝12dB。UE根据调度的波形以及RB的起始位置和数量，以及额外的NS要求，确定max(MPR f,c，A-MPR f,c)+ΔMB P,n，如果max(MPR f,c，A-MPR f,c)+ΔMB P,n＝9dB，预设触发条件P-MPR>max(MPR f,c，A-MPR f,c)+ΔMB P,n，可知，需要上报包含P-MPR值，本实施例中不是直接上报P-MPR值，而是根据计算公式P-MPR-(max(MPR f,c，A-MPR f,c)+ΔMB P,)的结果进行 上报，即12-9＝3dB，如以0.5dB为粒度，若在P-MPR上报格式中P-MPR值用6位比特表示，P-MPR＝3dB可对应于P-MPR_6，比特位表示如图7所示，具体地，P-MPR值＝3dB表示为000110。如以1dB为粒度上报，若在P-MPR上报格式中P-MPR值用5位比特表示，P-MPR值＝3dB可对应于表2中的P-MPR_3，比特位表示如图8所示，具体地，P-MPR值＝3dB表示为00011。
UE在某次通信中，根据业务类型和使用的场景确定该波束需要的P-MPR值，如P-MPR值＝6dB，预设触发条件为P-MPR值是否大于P0，其中P0为某一固定值，比如3dB，UE判断P-MPR值是否超过P0，如果超过，则触发包含P-MPR值的PHR信息上报，具体的格式可如图3或者图4所示。
应理解，图3～8所示的上报格式为一种可选的具体实现方式，但不限于此。
还应理解，图3～8所示的上报格式仅仅是为了示例本公开实施例，本领域技术人员可以基于图3～8的例子进行各种显而易见的变化和/或替换，得到的技术方案仍属于本公开实施例的公开范围。
