Description

一种功率控制方法和通信设备
本申请要求于2016年11月04日提交中国专利局、申请号为201610978238.0、申请名称为“一种功率控制方法和通信设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及通信领域，尤其涉及一种功率控制方法和通信设备。
背景技术
为了满足单用户峰值速率和系统容量提升的要求，一种方式是通过增加系统传输带宽，因此，长期演进(Long Term Evolution-Advanced，LTE-Advanced)系统引入一项增加传输带宽的技术，即载波聚合(Carrier Aggregation，CA)，CA技术可以将2～5个LTE载波(Component Carrier，CC)聚合在一起，实现最大100MHz的传输带宽，有效提高了上下行传输速率。再一种方式是通过双连接(Dual Connectivity，DC)技术提升用户数据的吞吐量。DC技术的本质是在非理想回程线路(Backhaul)前提下的载波聚合站点间的载波聚合。其典型的场景是有一个宏蜂窝(主小区)基站，另一个为小蜂窝(辅小区)基站，宏蜂窝基站和小蜂窝基站通过标准的X2接口相连。宏蜂窝基站和小蜂窝基站的调度器分别管理各自小区的无线资源，需要相互之间进行协调。双连接通过宏蜂窝基站进行移动性管理，同时聚合小蜂窝提供额外的用户容量，提高用户数据吞吐量。
多载波的功率控制模式在LTE/LTE-A中有两种模式：Mode1和Mode2，Mode1采用Look ahead方式，各个不同小区组(Cell Group，CG)的功率分配是根据信道类型的优先级进行的，根据基站配置的最大保证功率(Maximum Guaranteed Power,MGP)分配预先定义的各个CG的保证功率和可共享传输功率区间，可共享功率区间的功率根据传输信道的类型进行分配。Mode2采用Non-Look ahead模式，各个不同CG的功率分配根据时间上的顺序进行，根据基站配置的MGP分配预先定义的各个CG的保证功率和可共享传输功率区间，可共享功率区间的功率根据信道传输时间上的顺序进行分配，如图1所示为DC技术中的Mode1和Mode2的一种示意图。
现有的LTE中CA的功率控制方式采用的是Mode1，且仅考虑了一个子帧在时间上存在部分重叠时的功率控制，例如UE配置了多时间提前量(Multi-Timing Advance，MTA)，如果对于一个定时提前组(Timing Advance Group，TAG)中给定的小区在子帧i传输物理层上行共享信道(Physical Uplink Shared Channel，PUSCH)和在另一个TAG中的不同服务小区在子帧i+1传输的物理层上行控制信道(Physical Uplink Control Channel，PUCCH)重叠，UE将调整TAG的整体功率，使得在任意重叠部分功率不超过预定的最大功率，这种仅考虑重叠的一个子帧的功率的情况无法满足在采用不同的子载波间隔时，一个载波上的时域资源单元(slot)对应另一个载波上的多个时域资源单元时，将会导致功率分配不合理，使得传输性能下降。现有的LTE中DC 的功率控制可采用Mode1和Mode2，也仅考虑了一个子帧在时间上存在部分重叠时的功率控制，没有考虑多种子载波间隔共存时的功率控制，即一个载波上的时域资源单元对应另一个载波上的多个时域资源单元情况下的功率控制，也将导致功率分配不合理，使得传输性能下降。
发明内容
本发明实施例提供一种功率控制方法和通信设备，能够解决新无线接入技术(New RAT，NR)中采用多种子载波间隔时CA技术和DC技术中功率分配不合理的问题。
第一方面，提供一种功率控制方法，包括对配置多个小区的终端，根据子载波间隔，对多个小区划分小区组，小区组间的功率控制模式由基站配置为第一功率控制模式或第二功率控制模式，多个小区为载波聚合CA或双连接DC中的一种。其中，第一功率控制模式用于根据信道类型的优先级或小区组类型的优先级分配传输功率，可以为Look-ahead模式，第二功率控制模式用于根据传输信道或小区组发送的时间顺序进行功率分配，可以为Non Look-ahead模式。小区至少为载波或服务小区中的一种，这样，对于同一小区组内的载波，均为子载波间隔相同的载波，相同的子载波间隔对应的载波的时隙大小相同，可以避免多种不同的载波共存时一个载波上的时域资源单元对应另一个载波上的多个时域资源单元，使得子载波间隔相同的载波在相同的时域资源单元下的功率分配合理。

第二方面，提供一种功率控制方法，包括：终端向基站发送第一上报信息，第一上报信息指示不同的载波集合或频段集合的功率分配方式，载波集合包括至少一个载波，频段集合包括至少一个频段。由于现有技术只考虑了低频段即小于6GHz的载波的一个低频段的功率共享机制，但是在下一代无线通信技术例如5G通信技术中会引入大于6的载波或频段，例如30GHz的载波，高频段与低频段的载波或频段的功率放大对功率放大器的功放效率要求不同，可能会存在高频段与低频段采用不同功率放大器的场景，如何在这种场景下实现功率分配机制需要终端侧上报功率共享信息，而此功率共享信息指示不同的载波集合或频段集合之间是否能够共享传输功率。功率分配方式包括不同的载波集合或频段集合采用独立功率控制，独立功率控制包括至少一个载波集合或至少一个频段集合的最大传输功率是独立预定义的。
在一种可能的设计中，终端中预定义有至少一个载波集合或至少一个频段集合的最大传输功率，以及可共享功率的至少一个载波集合或至少一个频段集合的总最大传输功率。

在一种可能的设计中，第一功率控制模式用于根据信道类型的优先级或小区组类型的优先级分配传输功率，第二功率控制模式用于根据传输信道或小区组发送的时间顺序进行功率分配。
第四方面，提供一种终端，包括：确定单元，用于确定至少一个载波集合或至少一个频段集合的第一上报信息；发送单元，用于向基站发送第一上报信息，第一上报信息指示不同的载波集合或频段集合的功率分配方式，载波集合包括至少一个载波，频段集合包括至少一个频段。功率分配方式包括不同的载波集合或频段集合采用独立功率控制，独立功率控制包括至少一个载波集合或至少一个频段集合的最大传输功率是独立预定义的。
在一种可能的设计中，终端中预定义有至少一个载波集合或至少一个频段集合的最大传输功率，以及可共享功率的至少一个载波集合或至少一个频段集合的总最大传输功率。
第五方面，提供一种通信设备，包括：处理器，用于对配置多个小区的终端，根据子载波间隔，对多个小区划分小区组，小区组间的功率控制模式由基站配置为第一功率控制模式或第二功率控制模式，多个小区为载波聚合CA或双连接DC中的一种。第一功率控制模式用于根据信道类型的优先级或小区组类型的优先级分配传输功率，第二功率控制模式用于根据传输信道或小区组发送的时间顺序进行功率分配。小区至少为载波或服务小区中的一种。
在一种可能的设计中，处理器还用于：将相同子载波间隔的小区划分至同一小区组中，小区组内的小区间采用同一种功率控制模式，同一种功率控制模式为第一功率控制模式或第二功率控制模式。
第六方面，提供一种终端，包括：发送器，用于向基站发送第一上报信息，第一上报信息指示不同的载波集合或频段集合的功率分配方式，载波集合包括至少一个载波，频段集合包括至少一个频段。功率分配方式包括不同的载波集合或频段集合采用独立功率控制，独立功率控制包括至少一个载波集合或至少一个频段集合的最大传输功率是独立预定义的。终端中预定义有至少一个载波集合或至少一个频段集合的最大传输功率，以及可共享功率的至少一个载波集合或至少一个频段集合的总最大传输功率。
本发明实施例提供一种功率分配方法和通信设备，对配置多个小区的终端，可根据子载波间隔，对多个小区划分小区组，小区组间的功率控制模式由基站配置为第一功率控制模式或第二功率控制模式，多个小区为载波聚合CA或双连接DC中的一种。这样，对于同一小区组内的小区，均为子载波间隔相同的小区，相同的子载波间隔对应的小区的时隙大小相同，在小区为载波的情况下，可以避免多种不同的载波共存时一个载波上的时域资源单元对应另一个载波上的多个时域资源单元，使得子载波间隔相同的载波在相同的时域资源单元下的功率分配合理。

具体实施方式
本发明的技术方法可以应用于新无线接入技术(New RAT(Radio Access Technology，无线接入技术)，NR)中的CA或DC场景中，如图2所示为DC的应用场景的示意图，资源的调度由主基站(Master eNodeB，MeNB)和辅基站(Secondary eNodeB，SeNB)共同控制，终端(User Equipment，UE)可同时与MeNB和SeNB进行连接，实现多载波的调度。图3所示为DC的网络架构的示意图。如图4所示为CA的四种主要应用场景，但不限于这四种应用场景，包括：a)最典型的场景下，多个CC具有相同的波束方向或模式，且覆盖范围基本相同；b)在频谱离散部署的情况下，多个CC的传输功率不同，覆盖范围也不同；c)多个CC具有不同的波束方向或模式，且覆盖范围互补；d)宏小区(Macrocell)的CC提供覆盖功能，射频拉远(Remote Radio Head，RRH)的CC承载吞吐量。
在本发明实施例中，涉及的网元可以包括基站和终端，基站可以为eNodeB或演进型Node B(eNB)或传输接收点(Transmission Rrception Point，TRP)中的一种。终端可以为UE，eNB可以包括MeNB和SeNB，eNB时LTE中的基站，主要负责空口侧的无线资源管理、服务质量(Quality of Service，QoS)管理、数据压缩和加密等功能。在核心网侧，eNB主要负责向移动管理实体(Mobile Managenment Entity，MME)转发控制面信令以及向S-GW转发用户面业务数据，在NR中，与eNB对应的概念为TRP。UE可以为用户设备中的任意一种，并且UE可以是静态的，也可以是移动的。UE可以包括但不限于：站台(Station)、移动台(Mobile Station)、用户单元(Subscriber Unit)、个人电脑(Personal Computer)、膝上型电脑(Laptop Computer)、平板电脑(Tablet Computer)、上网本(Netbook)、终端(Terminal)、蜂窝电话(Cellular Phone)、手持设备(Handheld)、无绳电话(Cordless Phone)、个人数字助理(Personal Digital Assistant，缩写：PDA)、数据卡(Data Card)、通用串行总线(Universal Serial Bus，缩写：USB)插入设备、移动WiFi热点设备(MiFi Devices)、智能手表、智能眼镜、无线调制解调器(英文：Modem)、无线路由器、无线本地环路(Wireless Local Loop， 缩写：WLL)台等。
在本发明实施例中，提供一种功率控制方法，对配置多个小区的终端，根据子载波间隔，对多个小区划分小区组，小区组间的功率控制模式由基站配置为第一功率控制模式或第二功率控制模式，多个小区为载波聚合CA或双连接DC中的一种，这样，对于同一小区组内的小区，均为子载波间隔相同的小区，在小区为载波的情况下，相同的子载波间隔对应的载波的时隙大小相同，可以避免多种不同的载波共存时一个载波上的时域资源单元对应另一个载波上的多个时域资源单元，使得子载波间隔相同的载波在相同的时域资源单元下的功率分配合理。
在本发明实施例中，以小区为载波为例进行说明。
本发明实施例提供一种功率控制方法，如图5a所示，包括：
501、通信设备确定载波的子载波间隔。
502、通信设备对配置的多个载波的终端，根据子载波间隔，对载波划分载波组，多个载波为CA或DC中的一种。
该通信设备可以包括基站和/或终端，即对载波的组的划分可以是由基站侧、或终端侧、或基站和终端进行交互后划分的。
示例性的，基站在确定终端侧包括有不同子载波间隔的载波，基站可以将相同子载波间隔的载波划分至同一载波组。
例如在CA模式中，是将多个载波CC聚合在一起，该多个CC的子载波间隔可能相同，也可能不同，基站可以根据子载波间隔将相同子载波间隔的CC划分至同一载波组；在DC模式中，其本质也是在非理想Backhaul前提下的载波聚合站点间的载波聚合，在不同的应用场景中，该载波聚合中的子载波间隔也可能相同，也可能不同，基站也可以根据该载波聚合中子载波间隔将相同子载波间隔的CC划分至同一载波组。如图6所示，当两种子载波间隔的载波共存时，将第一种子载波间隔的CC1～CC3划分至第一载波组，将第二种子载波间隔的CC4～CC7划分至第二载波组。
503、基站配置不同的载波组间采用第一功率控制模式或第二功率控制模式，载波组内的载波采用同一种功率控制模式，同一种功率控制模式为第一功率控制模式或第二功率控制模式。
第一功率控制模式可以为Mode1模式，Mode1模式为Look-ahead模式，用于根据信道类型的优先级或载波组类型的优先级分配传输功率，第二功率控制模式可以为Mode2模式，Mode2模式为Non Look-ahead模式，用于根据传输信道或载波组发送的时间顺序进行功率分配。
不同的子载波间隔对应的时隙大小不同，即同一子载波间隔对应的每个时隙持续的时间长度相同，现有技术的功率控制方法中，仅考虑了重叠的一个子帧的功率，例如对于一个TAG中给定小区在子帧i传输PUCCH和在另一个TAG中的不同服务小区在子帧i+1传输的PUSCH重叠，终端将调整其整体功率，使得在重叠部分功率都不超过最大传输功率，但是当存在不同的子载波间隔的载波时，一个载波上的时域资源单元对可能对应另一个载波上的多个时域资源单元，例如如图7所示，第一子载波间隔对应的一个子帧的时间长度如(1)所示，表示15kHz的子载波间隔对应的一个子帧的时间长度A，用于传输上行数据，第二子载波间隔对应的多个子帧的时间长度如 (2)所示，表示60kHz的子载波间隔对应的四个子帧的时间长度B、C、D和E，用于传输上行或下行数据，15kHz的子载波间隔的一个子帧的时间长度对应60kHz的子载波间隔的四个子帧的时间长度，现有的功率分配会导致功率分配不合理，而在本发明中，当将相同子载波间隔的载波划分至同一载波组中时，则对于同一载波组内的载波，均为子载波间隔相同的载波，相同的子载波间隔对应的载波的时隙大小相同，可以使得终端避免多种不同的载波共存时一个载波上的时域资源单元对应另一个载波上的多个时域资源单元，使得子载波间隔相同的载波在相同的时域资源单元下的功率分配合理。
504、基站向终端发送信令，信令包括基站配置的不同的载波组间的功率控制模式的指示信息。
当终端接收到该信令时，由于载波组中的载波对应的时隙大小相同，避免了多种不同的载波共存时一个载波上的时域资源单元对应另一个载波上的多个时域资源单元的情况，又由于同一子载波间隔对应的载波的功率控制模式相同，可使得终端合理分配子载波间隔相同的载波的功率。
如图8所示，当存在第一子载波间隔的载波CG_Num1和第二子载波间隔的载波CG_Num2时，为CG_Num1分配保证功率(Guaranteed power)，并为CG_Num1分配Guaranteed power，但是，本申请不是直接如现有技术中在Look-ahead模式中按照信道类型进行功率分配，也不是直接如现有技术中在Non Look-ahead模式中按照时间的先后顺序为信道进行功率分配，而是增加载波的划分维度，将相同子载波间隔的载波划分至同一载波组，由于CG_Num1在子帧上所占用的时隙大小相同，CG_Num2在子帧上所占用的时隙大小相同，避免了多种子载波间隔的载波共存时一个子载波上的时域资源单元对应另一个载波上的时域资源单元的情况，且载波组CG_Num1和载波组CG_Num2间可以使用Look-ahead功率控制模式或Non Look-ahead功率控制模式，CG_Num1内的载波使用Look-ahead功率控制模式，CG_Num2内的载波使用Look-ahead功率控制模式，以使得多种子载波间隔共存时功率分配合理，提高传输性能。
需要说明的是，在本发明中，CA模式下的功率分配可以采用Look-ahead功率控制模式或Non Look-ahead功率控制模式，相对于现有技术中CA模式下的功率分配仅采用Look-ahead模式来说功率分配模式更为灵活。
因此，本发明实施例提供一种功率控制方法，对配置多个小区的终端，根据子载波间隔，对载波划分载波组，载波组间可采用第一功率控制模式或第二功率控制模式，由基站侧配置，第一功率控制模式与第二功率控制模式不同，多个载波为CA或DC中的一种，基站向终端发送信令，信令包括基站确定的不同载波组间的功率控制模式的指示信息，这样，对于同一载波组内的载波，均为子载波间隔相同的载波，相同的子载波间隔对应的载波的时隙大小相同，可以避免多种不同的载波共存时一个载波上的时域资源单元对应另一个载波上的多个时域资源单元，使得子载波间隔相同的载波在相同的时域资源单元下的功率分配合理。
本发明实施例还提供一种功率控制方法，如图5b所示，包括：
601、终端确定至少一个载波集合或至少一个频段集合的功率共享信息。
由于现有技术中仅考虑了低频段即6GHz以下的载波的功率共享机制，即为6GHz以下的载波如何共享功率分配。但是在下一代无线通信技术例如5G通信技术中会引入大于6GHz的载波或频段，例如30GHz的载波，高频段与低频段的载波或频段的功率放大对功率放大器的功放效率要求不同，可能会存在高频段与低频段采用不同功率放大器的场景，如何在这种场景下实现功率分配机制需要终端侧上报功率共享信息，而此功率共享信息指示不同的载波集合或频段集合之间是否能够共享传输功率。
602、终端发送第一上报信息，第一上报信息指示不同的载波集合或频段集合的功率分配方式，载波集合包括至少一个载波，频段集合包括至少一个频段。
功率分配方式包括不同载波集合或频段集合采用独立功率控制，独立控制包括至少一个载波集合或至少一个频段集合的最大传输功率是独立预定义的。
示例性的，假设存在两个频段集合，低频段的频段集合，和高频段的频段集合，终端在确定低频段的频段集合与高频段的频段集合是否可共享传输功率时，第一上报信息以1个bit来指示，该bit为0时表示可共享传输功率，为1时表示不可共享传输功率。同理，也可以包括高频段的载波集合和低频段的载波集合，或包括高频段、中频段和低频段的载波集合，或者包括以其他频段区域划分的多种载波集合，本申请不做限定。
也就是说，第一上报信息可以是终端根据配置的载波类型或频段类型确定的，第一上报信息还可以包括可以共享传输功率的载波集合的标识或频段集合的标识。载波集合包括至少一个载波，频段集合包括至少一个频段。
示例性的，终端可以根据CC的类型向基站上报第一上报信息，CC的类型可以根据终端所处的应用场景的不同而不同，例如在CA场景中，CC的类型可以包括具有相同波束方向的载波，传输功率不同的载波，具有不同波束方向的载波等，频段类型可以包括终端支持的频段值或频段范围，终端可以将能够进行功率共享的载波类型的CC归为一个载波集合，例如两种载波类型的CC可共用一个功率放大器(Power Amplifier，PA)，这两种载波类型的CC可归为一个载波集合中，终端可以将该载波集合中每个CC的标识上报给基站，这样以便于基站在接收到终端发送的N个载波集合或N个频段集合的功率共享信息时，可由基站侧配置终端的功率控制模式或功率控制类型。
在本发明实施例中，终端可以包括预定义的至少一个载波集合或至少一个频段集合的最大传输功率，以及预定义的可共享功率的至少一个载波集合或至少一个频段集合的总最大传输功率。
由此，通过终端向基站上报功率共享信息，可以使得基站合理地为不同载波集合或不同频段集合的载波配置高效的功率分配模式。
上述主要从各个网元之间交互的角度对本发明实施例提供的方案进行了介绍。可以理解的是，各个网元，例如基站、UE等为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。本领域技术人员应该很容易意识到，结合本文中所公开的实施例描述的各示例的单元及算法步骤，本发明能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。专业技术人员可以对每个特定的应用来使用不同方法来实现所描述的功能，但是这种实现不应认为超出本发明的范围。
本发明实施例可以根据上述方法示例对基站进行功能模块的划分，例如，可以对应各个功能划分各个功能模块，也可以将两个或两个以上的功能集成在一个处理模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。需要说明的是，本发明实施例中对模块的划分是示意性的，仅仅为一种逻辑功能划分，实际实现时可以有另外的划分方式。
