Abstract

本发明公开了一种上报功率余量报告的方法，所述方法包括：用户设备(UE)接收服务小区配置信息；根据所述服务小区配置信息确定功率余量报告(PHR)中第一域与所述服务小区的对应关系；其中，所述第一域用于指示PHR中是否包含服务小区的功率余量信息。本发明还同时公开了另一种上报功率余量报告的方法、两种上报功率余量报告的装置及计算机存储介质。

Description

一种上报功率余量报告的方法、装置及存储介质 技术领域
本发明涉及通信技术领域，尤其涉及一种上报功率余量报告(Power Headroom Report，PHR)的方法、装置及存储介质。
背景技术
随着通信技术的不断发展、智能终端的普及、以及大量网络应用的涌现，以数据业务为主的移动宽带通信成为未来移动通信发展的必然趋势。数据业务的高速发展使得对数据的传输峰值速率和带宽需要越来越高，因此，也需要通信系统提供更大的通信带宽；如：为满足长期演进(Long Term Evolution，LTE)系统下行峰值速率1Gbps/s和上行峰值速率500Mbps/s的要求，需要通信系统提供最大100MHz的传输带宽；对于宽带宽的连续频谱的稀缺，第三代合作伙伴计划(the 3rd Generation Partner Project，3GPP)在R10阶段提出的解决方案是载波聚合(Carrier Aggregation，CA)，并在R11和R12阶段对CA进行了进一步增强。用于移动通信的频谱分散与800MHz、900MHz、1800MHz、2400MHz和2600MHz，通过CA技术可以将这些分散的频谱聚合为大的通信带宽，增加频谱应用的灵活性，提高频谱的利用效率，CA技术是保证LTE系统能够满足数据的传输峰值速率需求和带宽需求的核心技术。
在3GPP的R8和R9阶段，CA用户设备(User Equipment，UE)只有一个服务小区，只能在一个载波上接收和发送数据；在3GPP的R10阶段，CA UE最多可以有五个服务小区，在五个载波上同时接收和发送数据，其中包括一个主小区(Primary Cell，PCell)和四个辅小区(Secondary Cells，SCell)，PCell是UE初始接入时的小区，负责与UE之间的无线资源控制 (Radio Resource Control，RRC)通信；SCell是RRC重配置时添加的，用于提供额外的无线资源，CA下的主小区和辅小区结构，如图1所示，PCell具有上行载波和下行载波，而SCell可以只有下行载波，但不能只有上行载波，并且物理上行控制信道(Physical Uplink Control Channel，PUCCH)只能在PCell上发送，PUCCH中传输的控制信息包括：上行资源调度请求、下行数据的确认/不确认(ACK/NACK)反馈、以及信道质量指示信息等。随着具有CA能力的UE数量不断增加，携带PUCCH的PCell的负载将显著增加，进而导致通信系统性能的下降，降低用户的体验。
在3GPP R13阶段，LTE系统能够支持的最大可聚合的载波数将上升至32个，即：一个PCell和三十一个SCell；现有标准中，为了让eNB进行上行资源调度时，对UE侧功率剩余情况有更好的了解，协议定义了报告功率余量的过程，报告功率余量用于向eNB提供UE的最大传输功率与当前上行同步信道(Upline-SynchroIluauon Channel，UL-SCH)传输功率估计值之间的差异信息；功率余量报告由媒体接入控制(MediumAccessControl，MAC)control element携带并被包含在MAC电源分配单元(Power Distribution Unit，PDU)中发送给基站。
PHR的第一域用以表示服务小区标识(Identity，ID)或SCell索引号(Index)为i的小区的功率余量信息是否存在于该PHR中，第一域可以为PHR中的第一个比特，第一域的值为1，表示Scell Index为i的小区的功率余量信息存在于此PHR中；第一域的值为0，表示Scell Index为i的小区的功率余量信息不存在于此PHR中。
在3GPP的R12阶段之前的协议中，UE最大支持的服务小区个数为5个，但是在3GPP的R13阶段，UE最大支持的服务小区个数将扩展至32个；此时，若仍使用第一域的方式指示服务小区的功率余量是否包含在PHR中，则需要32比特，增大了PHR中第一域的比特数。

Figure PCTCN2015095335-appb-000001
表1
目前，用于同时上报多个载波的功率余量信息的PHR格式主要有双链接功率余量报告Dual Connectivity Power Headroom Report和扩展功率余量报告Extended Power Headroom Report两种，分别对应LCH索引号为11000 和11001；其中，Dual Connectivity Power Headroom Report的上报格式，如图3所示；Extended Power Headroom Report的上报格式，如图4所示；两种上报格式中的第一域用以表示SCell Index为i的小区的功率余量信息是否存在于功率余量报告中，第一域的值为1，则表示SCell Index为i的小区的功率余量信息存在于功率余量报告中；第一域的值为0，则表示SCell Index为i的小区的功率余量信息不存在于功率余量报告中；所述第一域可以为两种上报格式中的第一个比特。
本发明实施例中，接收UE支持的服务小区配置信息；根据所述服务小区配置信息确定功率余量报告PHR中第一域与所述服务小区的对应关系；其中，所述第一域用于指示PHR中是否包含服务小区的功率余量信息。
本发明实施例一种上报功率余量报告的方法的基本处理流程，如图5所示，包括以下步骤：
步骤101，UE接收服务小区配置信息；
具体地，UE接收演进型基站(evolved Node B，eNB)发送的UE支持的服务小区配置信息并保存，所述服务小区配置信息可携带于RRC消息中。
步骤102，根据所述服务小区配置信息确定PHR中第一域与所述服务小区的对应关系；
具体地，UE先根据所述服务小区配置消息确定所述PHR中第一域与所述服务小区的映射方式，再根据确定的映射方式确定所述PHR中第一域与所述服务小区的对应关系；在确定所述第一域与所述服务小区的对应关系之前，UE还可以确定必须上报功率余量的服务小区，确定存在必须上报功率余量的服务小区后，所述第一域中不携带必须上报功率余量的服务小区的功率余量信息；
这里，根据所述服务小区配置信息确定配置PUCCH的服务小区为必须上报功率余量的服务小区；或，根据所述服务小区配置信息确定不能去激 活，且配置上行资源的服务小区为必须上报功率余量的服务小区；或，根据3GPP 36系列协议约定确定必须上报功率余量的服务小区；其中，所述上行资源配置包括：PUSCH的相关参数、上行功率控制的相关参数、Sounding RS的相关参数、CQI上报的相关参数和PUCCH的相关参数中的任意一种或任意多种的组合。
UE根据所述服务小区配置消息确定所述PHR中第一域与所述服务小区的映射方式，具体为：UE根据所述服务小区配置消息中的显式指示信息确定所述PHR中第一域与所述服务小区的映射方式；或，根据所述服务小区配置消息中配置的服务小区个数与第一阈值的关系确定所述PHR中第一域与所述服务小区的映射方式；或，根据所述服务小区配置消息中配置的包含上行资源的服务小区个数与第二阈值的关系确定所述PHR中第一域与所述服务小区的映射方式。
其中，所述第一域位于所述PHR中的第一个比特，用于指示PHR中是否包含服务小区的功率余量信息，所述第一域中每个比特用于指示一个服务小区的功率余量是否包含在所述PHR中，所述第一域总的比特数小于UE支持同时配置的服务小区个数最大值；所述第一域的长度，即所述第一域的总比特数可以为固定长度，或根据UE配置的拥有上行资源的服务小区的个数变化，或由eNB进行配置，通过RRC消息通知UE。
本发明实施例中，所述第一域与所述服务小区的映射方式包括两种，一种为传统的映射方式，即：第一域中的每个比特与全部的SCell一一对应；另一种为本发明实施例中新的映射方式，即：根据实际配置的服务小区个数确定第一域中的比特与部分服务小区存在对应关系的映射方式；根据实际配置的服务小区个数确定的映射方式具体为：在服务小区配置消息中的显式指示信息为新的映射方式时，确定所述PHR中第一域与所述服务小区的映射方式为新的映射方式；或，所述服务小区配置消息中配置的服务小 区个数大于第一阈值时，确定所述PHR中第一域与所述服务小区的映射方式为新的映射方式；或，根据所述服务小区配置消息中配置的包含上行资源的服务小区个数大于第二阈值的关系确定所述PHR中第一域与所述服务小区的映射方式为新的映射方式；由于现有协议中能够支持的最大小区个数为7个，因此，所述第一阈值和第二阈值可设定为7；所述第一域中每个比特值为0，表示该比特对应的服务小区的于玲报告不存在与该PHR中，所述第一域中每个比特值为1，表示该比特对应的服务小区的功率余量信息存在于该PHR中，所述第一域中的比特对应的服务小区按照SCell Index由低到高的顺序或由高到低的顺序指示服务小区的功率余量信息是否存在于该PHR中。
本发明实施例中，所述PHR中的一个比特用于指示所述PHR中第一域与所述服务小区的映射方式；所述比特值为0时，表示所述映射方式为传统的映射方式，所述比特值为1时，表示所述映射方式为新的映射方式；所述比特可以为PHR中保留的比特，或者是新引入的比特；所述PHR中的另一个比特用于指示所述PHR中第一域与所述服务小区的映射方式是否发生改变，所述另一个比特值为0时，表示所述映射方式未发生改变，所述另一个比特值为1时，表示所述映射方式发生改变；所述传统的映射方式的PHR与新的映射方式的PHR可采用不同的LCH ID；所述另一个比特可以为PHR中保留的比特，或者是新引入的比特；在所述另一个比特值发生变化时，表示所述映射方式发生变化，将所述指示PHR中第一域与所述服务小区的映射方式的比特值修改为变化后的映射方式对应的比特值；这里，所述指示所述PHR中第一域与所述服务小区的映射方式比特和所述指示所述PHR中第一域与所述服务小区的映射方式是否发生改变比特可以为PHR中的除指示PHR中是否包含服务小区的功率余量信息的比特外的任意比特。
需要说明的是，本发明实施例中，不同比特值表示的含义可根据需要灵活设置，并不限定于本发明实施例所述的比特值设置方式。
本发明实施例另一种上报功率余量报告的方法的基本处理流程，如图6所示，包括以下步骤：
步骤201，UE接收服务小区配置信息；
具体地，UE接收eNB发送的UE支持的服务小区配置信息并保存，所述服务小区配置信息可携带于RRC消息中。
步骤202，根据所述服务小区配置信息确定PHR中第一域的长度；
具体地，UE根据所述服务小区配置消息中的指示信息确定PHR中第一域的长度；或，根据所述服务小区配置消息中配置的上行资源的辅服务小区个数确定PHR中第一域的长度；所述PHR中第一域的长度等于UE配置的拥有上行资源的辅服务小区个数。
根据所述服务小区配置信息确定配置PUCCH的服务小区为必须上报功率余量的服务小区；或，根据所述服务小区配置信息确定不能去激活，且配置上行资源的服务小区为必须上报功率余量的服务小区；或，根据3GPP 36系列协议约定确定必须上报功率余量的服务小区；此时，在计算第一域的长度时，应减去不需要第一域指示的SCell的个数；
其中，所述第一域位于所述PHR中的第一个比特，用于指示PHR中是否包含服务小区的功率余量信息，所述第一域中每个比特用于指示一个服务小区的功率余量是否包含在所述PHR中，所述第一域总的比特数小于UE支持同时配置的服务小区个数最大值。
实施例一
本发明实施例一上报功率余量报告的方法的详细处理流程，如图7所示，包括以下步骤：
步骤301，UE接收eNB发送的第一RRC重配置消息，并保存所述RRC 重配置消息中携带的第一服务小区配置信息；
具体地，本发明实施例一中，所述第一RRC重配置消息中一共配置了10个服务小区；其中，第1个服务小区为PCell，第2个至第10个服务小区为SCell，第2个至第10个服务小区对应的SCell Index为1-9，且SCell Index为1/3/5/7/9的SCell配置了上行资源。
步骤302，UE确认PHR中第一域与所述服务小区的映射方式；
具体地，UE根据所述服务小区配置消息中配置的服务小区个数与第一阈值的关系确定所述PHR中第一域与所述服务小区的映射方式；
这里，由于现有协议中能够支持的最大小区个数为7个，因此，所述第一阈值设为7，配置的服务小区个数大于第一阈值，确定所述PHR中第一域与所述服务小区的映射方式为：所述第一域中的比特与部分服务小区存在对应关系；所述第一域中的第1/2/3/4/5比特分别对应SCell Index为1/3/5/7/9的小区；
其中，所述第一域用于指示PHR中是否包含服务小区的功率余量信息，所述第一域中每个比特用于指示一个服务小区的功率余量是否包含在所述PHR中。

这里，所述新的逻辑信道ID为：LCH ID 10111，LCH ID 10111对应的PHR格式与Extended Power Headroom Report一致，只是采用的第一域与所述服务小区的映射方式不同；此时，PHR的格式，如图10所示，其中，第1比特至第10比特分别对应SCell Index为1/3/5/7/9/11/13/15/17/19的小区。
实施例四
本发明实施例四上报功率余量报告的方法的详细处理流程，如图11所示，包括以下步骤：

具体地，本发明实施例四中，所述第四RRC重配置消息中一共配置了5个服务小区；其中，第1个服务小区为PCell，第2个至第5个服务小区为SCell，第2个至第5个服务小区对应的SCell Index为1-4，且SCell Index为1/2/4的SCell配置了上行资源；且所述RRC重配置消息中指定UE采用新DC的PHR上报格式，并采用新的第一域填写方式；
其中，新的上报格式指PHR中第一域的第i个比特指示SCell Index由低到高的第i个包含了上行资源配置服务小区的功率余量是否存在。
步骤602，UE确认PHR中第一域与所述服务小区的映射方式；
具体地，UE根据所述RRC重配置消息指定的PHR上报格式，第一域中的第1/2/3比特分别对应SCell Index为1/2/4的小区。

实施例五
本发明实施例五上报功率余量报告的方法的详细处理流程，如图12所示，包括以下步骤：
步骤701，UE接收eNB发送的第五RRC重配置消息，并保存所述RRC重配置消息中携带的第五服务小区配置信息；

步骤702，UE确认PHR中第一域与所述服务小区的映射方式；
具体地，UE根据所述服务小区配置消息中配置的服务小区个数与第一阈值的关系确定所述PHR中第一域与所述服务小区的映射方式；
这里，由于现有协议中能够支持的最大小区个数为7个，因此，所述第一阈值设为7，配置的服务小区个数大于第一阈值，确定所述PHR中第一域与所述服务小区的映射方式为：所述第一域中的比特与部分服务小区存在对应关系；所述第一域中的第1/2/3/4/5比特分别对应SCell Index为1/3/5/7/9的小区；
其中，所述第一域用于指示PHR中是否包含服务小区的功率余量信息，所述第一域中每个比特用于指示一个服务小区的功率余量是否包含在所述PHR中。
步骤703，UE填写PHR，使用原来的逻辑信道ID表示此PHR中采用了Extended Power Headroom Report格式，此时，PHR的格式，如图13所示；
这里，将PHR报告中指示第一域采用的映射方式的比特值设置为0，如图13中第一行最后一列所述“R”值。
步骤704，UE接收eNB发送的第六RRC重配置消息，并保存所述RRC重配置消息中携带的第六服务小区配置信息；
这里，所述第六RRC重配置消息中指示UE删除SCell Index为5/6/7/8/9的服务小区，仅保留SCell Index为1/2/3/4的服务小区。
步骤705，UE确认PHR中第一域与所述服务小区的映射方式后，填写PHR；
具体地，UE根据所述服务小区配置消息中配置的服务小区个数与第一阈值的关系确定所述PHR中第一域与所述服务小区的映射方式；
这里，所述第一阈值根据协议规定设为7，配置的服务小区个数小于第一阈值，则采用传统的映射方式；此时，由于第一域与所述服务小区的映射方式发生了改变，UE将PHR中指示第一域与所述服务小区的映射方式的比特值进行修改。
为实现上述上报功率余量报告的方法，本发明实施例还提供一种上报功率余量报告的装置，所述装置的组成结构，如图14所示，包括：第一接收模块11和第一确定模块12；其中，

本发明实施例中，所述第一域与所述服务小区的映射方式包括两种，一种为传统的映射方式，即：第一域中的每个比特与全部的SCell一一对应；另一种为本发明实施例中新的映射方式，即：根据实际配置的服务小区个数确定第一域中的比特与部分服务小区存在对应关系的映射方式；根据实 际配置的服务小区个数确定的映射方式具体为：在服务小区配置消息中的显式指示信息为新的映射方式时，确定所述PHR中第一域与所述服务小区的映射方式为新的映射方式；或，所述服务小区配置消息中配置的服务小区个数大于第一阈值时，确定所述PHR中第一域与所述服务小区的映射方式为新的映射方式；或，根据所述服务小区配置消息中配置的包含上行资源的服务小区个数大于第二阈值的关系确定所述PHR中第一域与所述服务小区的映射方式为新的映射方式；由于现有协议中能够支持的最大小区个数为7个，因此，所述第一阈值和第二阈值设定为7；所述第一域中每个比特值为0，表示该比特对应的服务小区的于玲报告不存在与该PHR中，所述第一域中每个比特值为1，表示该比特对应的服务小区的功率余量信息存在于该PHR中，所述第一域中的比特对应的服务小区按照SCell Index由低到高的顺序或由高到低的顺序指示服务小区的功率余量信息是否存在于该PHR中。
