Description

上行数据的传输方法、终端设备和基站
本申请要求于2017年11月16日提交中国专利局、申请号为201711140388.5、申请名称为“上行数据的传输方法、终端设备和基站”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，并且更具体地，涉及一种上行数据的方法、终端设备和基站。
背景技术
在长期演进(long term evolution，LTE)系统，终端设备向演进型基站(evolutional node B，eNB)发送功率余量报告(power headroom report，PHR)。PHR是一组由功率余量(power headroom，PH)组成的媒体接入控制(media access control，MAC)控制单元(control element，CE)。PHR可以为eNB提供进行功率控制和调度的信息。PHR是根据调度单位来上报的。eNB可以根据PHR为终端设备的上行传输选择合适的调制与编码策略(modulation and coding scheme，MCS)和资源大小。
在LTE中，PH上报的单位为小区，也即基站为终端设备进行上行调度的单位。但是，以小区为单位上报PH的方式已经不能满足第五代(5th generation，5G)新空口(new radio，NR)系统，因此，亟需提出一种新的解决方案。

无线接入网设备是终端设备通过无线方式接入到该移动通信系统中的接入设备，可以是基站NodeB、演进型基站eNodeB、5G移动通信系统中的基站gNB、未来移动通信系统中的基站或WiFi系统中的接入节点等，本申请的实施例对无线接入网设备所采用的具体技术和具体设备形态不做限定。
终端设备也可以称为终端Terminal、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端(mobile terminal，MT)等。终端设备可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(virtual reality，VR)终端设备、增强现实(augmented reality，AR)终端设备、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程手术(remote medical surgery)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。
无线接入网设备和终端设备可以部署在陆地上，包括室内或室外、手持或车载；也可以部署在水面上；还可以部署在空中的飞机、气球和人造卫星上。本申请的实施例对无线接入网设备和终端设备的应用场景不做限定。为了便于描述，下文以无线接入网设备是基站为例进行描述。
本申请的实施例可以适用于下行信号传输，也可以适用于上行信号传输，还可以适用于设备到设备(device to device，D2D)的信号传输。对于下行信号传输，发送设备是无线接入网设备，对应的接收设备是终端设备。对于上行信号传输，发送设备是终端设备，对应的接收设备是无线接入网设备。对于D2D的信号传输，发送设备是终端设备，对应的接收设备也是终端设备。本申请的实施例对信号的传输方向不做限定。

图2是本申请实施例的另一个无线通信系统架构图。如图2所示，UE位于宏基站 (Macro eNB)或小基站(small eNB)提供的一个或多个小区(载波)的覆盖范围内。为UE服务的小区可以为一个或多个。当多个小区为UE服务时，UE可以按照载波聚合(carrier aggregation，CA)，或双连接，或多连接，或协作多点传输(coordinated multiple point transmission，CoMP)方式工作。其中，至少一个小区提供多于一种基础参数集numerology(空口格式)同时为UE提供无线资源。
NR中频谱的使用会拓展到更高的频段，如C-band乃至更高的频域。但是高频段的数据传输会有较大的路径衰减和较差的覆盖范围。对于下行链路，由于基站有较大的发送功率，较强的射频器件和较多的天线，高频数据通道的衰减问题可以得到缓解。但是对于上行链路，由于终端设备的能力有限，覆盖范围小的问题比较难以解决。因此，NR中提出了补充上行链路(supplementary uplink，SUL)的设计，即在原有高频链路的基础上，补充低频链路来提高上行链路的可靠性和覆盖范围。
另外，由于高频传输的高带宽，高频率，不同的空口格式以及更高的终端设备的能力要求，NR中引入了频率段(bandwidth parts，BWP)的概念，主要应用场景包括以下场景中的至少一项：(1)支持终端设备更小的带宽能力；(2)通过改变带宽较少终端设备的能耗；(3)支持不同基础参数集(numerology)的频分复用；(4)支持非连续频谱；(5)支持前向兼容。
由于在NR中引入了上述补充上行链路SUL和频率段BWP的概念，现有技术是以小区为单位上报PHR的，已经不能解决基于上行链路SUL和频率段BWP上报功率余量报告(power headroom report，PHR)的问题，需要以更细的粒度为单位进行PHR的上报。因此，本申请拟提出一种上行数据的传输方法，拟基于上行子载波(carrier)和/或BWP为单位进行PHR的上报。
为了便于理解，下面对PHR的上报涉及到的一些概念进行描述。
PHR是一组由功率余量(power headroom，PH)组成的媒体接入控制(media access control，MAC)控制单元(control element，CE)。其中，每个PH表示终端设备在每个小区上允许的最大发送功率与传输功率的差值。具体地，终端设备根据上行授权(UL grant)中指示的物理资源和/或调制编码方式向基站上报PHR，以告诉基站自己的功率余量状态，如果终端设备有数据发送，基站就以终端设备上报的PHR和/或BSR作为参考，为该终端设备分配合适的上行传输资源，然后通过下发UL grant告知给该终端设备为其分配的上行传输资源，以便终端设备上报数据。应理解，PHR的发送需要有两个步骤：首先是触发，其次获得足够承载PHR的上行传输资源。
LTE中有三种PH的格式(Type)，分别是：
Type 1:当计算服务小区c子帧i的功率余量的时候，只计算物理上行共享信道(physical uplink shared channel，PUSCH)的传输功率，其中，c表示服务小区的编号，i表示子帧的编号；
Type 2：当计算服务小区c子帧i的功率余量的时候，计算PUSCH和物理上行控制信道(physical uplink control channel，PUCCH)的传输功率；
Type 3:当计算服务小区c子帧i的功率余量的时候，计算探测参考信号(sounding reference signal，SRS)的传输功率。
图3示出了根据本申请实施例的上行传输数据的方法300的示意性交互图。例如，图 3中的基站可以是图1中的无线接入网设备120，图3中的终端设备可以是图1中的终端设备130或终端设备140。如图3所示，所述方法300包括：
S301，基站向终端设备发送上行授权(UL grant)。
对应地，终端设备接收来自基站的上行授权。
S302，终端设备向所述基站发送报告，所述报告包括至少一个上行子载波中的每一个上行子载波的功率余量，和/或，至少一个频率段中的每一个频率段的功率余量。
对应地，所述基站接收所述报告。
可选地，所述报告可以是功率余量报告PHR，或者其他包括功率余量的消息，本申请实施例对此不作限定。为了便于描述，下文以所述报告是PHR为例进行描述。
可选地，所述每一个上行子载波可以是激活或者未激活的上行子载波。比如，UL carrier,SUL carrier或者non-SUL carrier。
应理解，本申请实施例的上行数据的传输方法仅以上行子载波为示例描述的，实际上，本申请实施例并不限于此，本申请实施例的方法也可以适用于上行载波。为了简洁，这里进行统一说明：本申请实施例中涉及到上行子载波的地方均可以替换为上行载波，以实现关于上行载波的方案，例如，所述报告包括至少一个上行载波中的每一个上行载波的功率余量，和/或，至少一个频率段中的每一个频率段的功率余量，等等。本领域技术人员根据本申请实施例的关于上行子载波的方案，可以明确得到关于上行载波的方案，下文不再赘述。
可选地，所述每一个频率段可以是激活或者未激活的频率段。
可选地，所述至少一个上行子载波和所述至少一个频率段可以位于同一服务小区。
可选地，所述至少一个频率段可以是同一上行子载波或不同上行子载波中的频率段，本申请实施例对此不作限定。
具体而言，终端设备向基站发送PHR的过程是：终端设备的MAC层根据功率余量PH信息构造PHR MAC CE，然后将PHR MAC CE组装到MAC协议数据单元(protocol data unit，PDU)中，然后通过物理层向所述基站发送MAC PDU。应理解，本申请实施例对发送PHR的具体手段不作限定。
在本申请实施例中，终端设备向所述基站发送报告，所述报告包括至少一个上行子载波中的每一个上行子载波的功率余量，和/或，至少一个频率段中的每一个频率段的功率余量，以更细粒度的上报功率余量，有助于基站调度的准确性。
可选地，作为一个实施例，所述报告包括第一媒体接入控制MAC实体上的报告，所述方法300包括：
在第一MAC实体所在的服务小区内，激活或者配置或者重配置所述第一MAC实体对应的如下中至少一种：上行子载波，频率段，以及上行共享信道；
所述终端设备触发所述第一MAC实体上的报告。
具体而言，本申请实施例提出了一种新的功率余量报告PHR的触发条件，以第一MAC实体所在的服务小区为例，包括以下情况：如果激活或者配置或者重配置了这个服务小区中第一MAC实体对应的上行子载波，那么可以触发第一MAC实体上的PHR；或者，如果激活或者配置或者重配置了该服务小区中第一MAC实体对应的频率段，那么可以触发第一MAC实体上的PHR；或者，如果激活或者配置或者重配置了该服务小区中第一MAC 实体对应的上行共享信道(比如，PUSCH)，那么可以触发第一MAC实体上的PHR。应理解，上述情况可以组合使用，对此不作限定。
可选地，上述触发条件也可以适用于多连接通信系统(比如双连接通信系统)。
可选地，作为一个实施例，所述服务小区包括多个MAC实体，所述服务小区是所述终端设备进行多连接通信过程中的服务小区，所述方法300还包括：
激活或者配置或者重配置所述多个MAC实体中第一MAC实体对应的如下中至少一种：上行子载波，频率段，以及上行共享信道；
所述终端设备触发所述多个MAC实体中的每个MAC实体上的功率余量报告，或者仅触发所述第一MAC实体上的功率余量报告。
具体地，在多连接(比如双连接)，如果满足上述触发条件，即服务小区中的某一个MAC实体(比如第一MAC实体)对应的上行子载波、频率段、以及上行共享信道中的至少一项被激活或者配置或者重配置，所述终端设备触发所有MAC实体上的PHR，或者，仅触发所述第一MAC实体上的PHR。
因此，本申请实施例针对配置了至少一个上行子载波或者至少一个频率段的服务小区，提出了新的PHR触发条件，在上行子载波、频率段、以及上行共享信道中的至少一种被激活或重配置时，使得终端设备能够及时地上报PHR，从而基站为终端设备做好调度。
进一步地，为了满足上行子载波或者频率段的PHR的上报，本申请实施例还提出了一种新的PHR MAC CE格式，以支持多上行子载波和频率段的PHR的上报。
可选地，作为一个实施例，S302包括：
所述终端设备使用第一上报方式向所述基站发送所述报告，其中，所述报告包括如下中至少一种：服务小区的标识信息，所述服务小区中所述每一个上行子载波对应的功率余量的信息，所述服务小区中所述每一个频率段对应的功率余量的信息，所述服务小区中所述每一个上行子载波对应的最大发送功率的信息，所述服务小区中所述每一个频率段对应的最大发送功率的信息。
具体而言，第一上报方式可以理解为终端设备基于每一个上行子载波或每一个频率段，确定的上报格式，终端设备使用所述第一上报方式向基站发送报告。
可选地，在一个服务小区内，所有激活或者未激活的上行子载波或者频率段的功率余量的信息(比如，PH值)是按照一定的顺序堆叠在一起上报的，其中，每一个功率余量的信息后面添加与格式对应的最大发送功率的信息。可选地，对功率余量的信息的上报顺序不作限定，可以按照上行子载波或者频率段的序号升序排列，或者降序排列，或者按照其他规律排列。
举例来说，在一个服务小区内，所述每一个上行子载波或每一个频率段的功率余量信息的格式包括格式2，以及格式1/3，确定所述第一上报方式为：其中，具有格式2的上行子载波或频率段对应的功率余量的信息后添加格式2对应的最大发送功率，或者，具有格式1/3的上行子载波或频率段对应的功率余量的信息后添加格式1/3对应的最大发送功率。
例如，对于配置在一个服务小区内的多个激活或者未激活的上行子载波或频率段的多个格式2的PH，在PHR格式中可以按照一定的顺序排列在一起放置。可选地，对于每个格式2的PH，如果有上行资源分配，则每个格式2的PH的后面要添加与之对应的最大 发送功率；或者，即使没有上行资源分配，也给每个格式2的PH的后面要添加与之对应的最大发送功率。
又例如，对于配置在一个服务小区内的多个激活或者未激活的上行子载波或频率段的多个格式1/3的PH，在PHR格式中可以按照一定的顺序排列在一起放置。可选地，对于每个格式1/3的PH，如果有上行资源分配，则每个格式1/3的PH的后面要添加与之对应的最大发送功率；或者，即使没有上行资源分配，也给每个格式1/3的PH的后面要添加与之对应的最大发送功率。
比如，图4示出了根据本申请实施例的上报方式的一个例子的示意图。如图4所示，第一行至第四行中的C 1至C 24为服务小区索引(小区Index)，R表示保留位；第五行至第十行中表示小区11中的PH，P用于指示是否进行功率回退，V用于指示PH值为真实的还是虚拟的，R表示保留位；以PH(格式x,BWP/UL 1)为例，PH括号内的格式x，x表示对应的格式类型(可以是格式2，也可以是格式1/3)，BWP表示频率段，1表示上行子载波的编号，PH(格式x,BWP/UL 1)后添加了对应的最大发送功率P CMAX,11 1。后续每个PH值后边添加对应的最大发送功率后续依次进行排列。
或者，可选地，作为一个实施例，S302包括：
所述终端设备使用第二上报方式向所述基站发送所述报告，所述报告包括如下中至少一种：服务小区的标识信息，所述服务小区中所述每一个上行子载波对应的功率余量的信息，所述服务小区中所述每一个频率段对应的功率余量的信息，所述服务小区对应的最大发送功率的信息。
具体而言，第二上报方式可以理解为终端设备基于每一个上行子载波或每一个频率段，确定的上报格式，终端设备使用所述第二上报方式向基站发送PHR。
可选地，在一个服务小区内，所有激活或者未激活的上行子载波或者频率段的功率余量的信息(比如，PH值)是按照一定的顺序堆叠在一起上报的，其中，所有功率余量的信息之前或之后添加与服务小区对应的最大发送功率的信息。可选地，对功率余量的信息的上报顺序不作限定，可以按照上行子载波或者频率段的序号升序排列，或者降序排列，或者按照其他规律排列。
举例来说，在一个服务小区内，所述每一个上行子载波或每一个频率段的功率余量信息的格式包括格式2，或格式1/3，确定所述第二上报方式为：对于同一服务小区，在所述每一个上行子载波或所述每一个频率段对应的所有功率余量的信息之前或之后，添加服务小区对应的最大发送功率。
可选地，对于同一服务小区，如果该服务小区中终端设备配置了PUSCH或PUCCH或SRS的功能，则在所有的PH后面添加与格式类型对应的最大发送功率
例如，图5是根据本申请实施例的上报方式的另一个例子的示意图。如图5中所示，第一行至第四行中的C 1至C 31为服务小区索引(cell Index)，R表示保留位；第五行至第八行中表示小区11中的PH，P用于指示是否进行功率回退，V用于指示PH值为真实的还是虚拟的，R表示保留位；以PH(格式x,BWP/UL 1)为例，PH括号内的格式x，x表示对应的格式类型(可以是格式2或者格式1或者格式3)，BWP表示频率段，1表示上行子载波的编号，所有PH(包括PH(格式x,BWP/UL 1)、PH(格式x,BWP/UL 3)、和PH(格式x,BWP/UL 7))后添加了同一个最大发送功率P CMAX,11。
进一步地，如果至少一个上行子载波中的某一个上行子载波(比如第一子载波)中配置有多个激活或者未激活的频率段，那么PHR的上报格式可以对每一个频率段按照一定的顺序排列上行子载波，随后，将剩余的上行子载波的功率余量的信息按序进行排列。应理解，所述第一子载波可以是至少一个上行子载波中的任一个。可选地，所述报告中可以包括第一子载波中上的多个频率段对应的功率余量的信息。可选地，第一子载波可以按照第一子载波在至少一个上行子载波中的顺序。可选地，终端设备可以为每一个上行子载波上激活或者未激活的频率段配置独立的最大发送功率，也可以为所有激活或者未激活的频率段配置一个共同的最大发送功率。
举例来说，如图6所示，对于小区20，存在M个上行(UL)子载波，其中，上行子载波1包括N个BWP。此时，PHR的上报格式可以将N个BWP对应的PH值按序排列，然后将上行(UL)子载波2至上行(UL)子载波M的PH值按序排列。
应理解，图6中只是以上行子载波1包括N个BWP为例进行描述，并不对本申请实施例构成限定，上述M个上行(UL)子载波中的任意一个上行(UL)子载波均可以包括多个BWP，同样适用本申请实施例的上报方式。
进一步地，所述报告中还可以包括第一指示信息，所述第一指示信息用于指示上报或不上报上行子载波对应的功率余量的信息，或者，用于指示上报或不上报频率段对应的功率余量的信息。
可选地，所示第一指示信息可以通过位图(bitmap)来表示，比如，用0表示不上报PH值，用1表示上报PH值。
也就是说，对于上述图4或图5中的上报格式，可以增加一个指示信息来指示是否上报。例如，如图7所示，与图4中的格式对应，具体参数介绍可以参照前文，区别在于在所有PH值的前面增加了指示信息，具体即：用C 7指示上行子载波7对应的PH(格式x,BWP/UL 7)是否上报，用C 3指示上行子载波3对应的PH(格式x,BWP/UL 3)是否上报，用C 1指示上行子载波1对应的PH(格式x,BWP/UL 1)是否上报。
同理，又例如，如图8所示，与图5中的格式对应，具体参数介绍可以参照前文，区别在于在PH值的前面增加了指示信息，具体即：用C 7指示上行子载波7对应的PH(格式x,BWP/UL 7)是否上报，用C 3指示上行子载波3对应的PH(格式x,BWP/UL 3)是否上报，用C 1指示上行子载波1对应的PH(格式x,BWP/UL 1)是否上报。
应理解，图4至图8中的例子仅仅是为了便于本领域技术人员理解本申请实施例，并非要将本申请实施例限于例示的具体场景。本领域技术人员根据图4至图8的例子，显然可以进行各种等价的修改或变化，这样的修改或变化也落入本申请实施例的范围内。
可选地，作为一个实施例，在S302前，所述方法300可以包括：
所述终端设备对所述每一个上行子载波，分别配置对应的最大发送功率，其中，所述每一个上行子载波分别对应的最大发送功率相同或不同；或者，
所述终端设备对所述每一个频率段，分别配置对应的最大发送功率，其中，所述每一个频率段分别对应的最大发送功率相同或不同；或者，
所述终端设备从物理层获取所述每个上行子载波对应的格式类型、所述格式类型对应的最大发送功率、所述格式类型对应的功率余量的信息中的至少一项；或者，
所述终端设备从物理层获取每个频率段对应的格式类型、所述格式类型对应的最大发 送功率、所述格式类型对应的功率余量的信息中的至少一项。
具体地，终端设备对所述每一个上行子载波或所述每一个频率段，配置对应的最大发送功率，包括以下方式：
以小区c上的上行第i个子载波或者BWP为例，该子载波或BWP的最大发送功率可以在如下的功率区间内配置：
P CMAX_L,c_UL_i≤P CMAX,c_UL_i≤P CMAX_H,c_UL_i，
其中，
P CMAX_L,c_UL_i＝MIN{P EMAX,c_UL_i–ΔT C,c_UL_i，(P PowerClass–ΔP PowerClass)–MAX(MPR c_UL_i+A-MPR c_UL_i+ΔT IB,c_UL_i+ΔT C,c_UL_i+ΔT ProSe,P-MPR c_UL_i)}
P CMAX_H,c_UL_i＝MIN{P EMAX,c_UL_i,P PowerClass–ΔP PowerClass}
其中，与现有协议不同的是：P EMAX,c_UL_i，P-MPR c_UL_iΔT IB,c_UL_i，ΔT C,c_UL_i，ΔT C,c_UL_i MPR c_UL_i和A-MPR c_UL_i都是在小区c上，以上行子载波或BWP为单位配置的。这里，公式中的其他参数的解释或定义可以参考协议3GPP中36.101(UE的无线传输和接收User Equipment(UE)radio transmission and reception)的定义。
或者，终端设备针对一个小区内所有激活或者未激活的上行子载波或者频率段配置一个最大的上行发送功率。
可选地，如果一个激活或者未激活的上行子载波上配置有多个激活或未激活的频率段，那么终端设备可以根据频率段，为每一个激活或者未激活的频率段配置不同的最大上行发送功率。或者，终端设备也可以为一个上行子载波上所有激活或者未激活的频率段配置共同的上行发送功率。
或者，对于每个服务小区内的激活或者未激活的上行子载波或频率段，终端设备在上报PHR时需要从物理层获得对应的格式(即上文描述的格式1/3，或者格式2)。比如，终端设备从物理层得知格式为格式1/3，如果小区内的激活或者未激活的上行子载波或频率段上有基站分配的上行资源(比如UL grant)，那么终端设备从物理层获得与格式1/3类型对应的最大发送功率。或者，终端设备可以对小区内所有激活或者未激活的上行子载波或频率段，直接从物理层得到与格式类型对应的最大发送功率。又比如，终端设备从物理层得知上行子载波或频率段配置了PUCCH或同时(simultaneous)配置了PUCCH和PUSCH，那么终端设备就从物理层得到对应的格式2的PH值和/或格式2对应的最大发送功率；或者，终端设备针对所有激活或者未激活的上行子载波或BWP，从物理层获得格式2的PH值和/或格式2对应的最大发送功率，该格式2对应的最大发送功率作为所有激活或者未激活的上行子载波或频率段的共同的最大发送功率。
综上所述，终端设备可以基于上行子载波或频率段，配置最大发送功率，或者从物理层获得最大发送功率。
可选地，作为一个实施例，在S302前，所述方法300还包括：
所述终端设备进行上行功率控制；
在进行所述上行功率控制后，所述终端设备计算所述每一个上行子载波的功率余量，或者所述每一个频率段的功率余量。
具体而言，在一个服务小区内，终端设备可以根据激活或者未激活的每一个上行子载波或者每一个频率段，进行上行功率控制。比如，如果某个上行子载波上配置有多个激活 的频率段，终端设备可以根据每一个激活的频率段作上行功率控制。因此，相比于LTE中以小区为单位进行上行功率控制，本申请实施例可以更细的粒度进行上行功率控制。
其中，功率控制是指在一定范围内，通过改变终端设备的发射功率，来补偿信道的路径损耗和阴影衰落，抑制同频小区间干扰，保证网络覆盖和终端设备的上行容量需求。功率控制分为对PUSCH、PUCCH和SRS上三种功率传输的控制。好的功率控制可以在保证业务质量、降低干扰、降低能耗的同时提升容量，进而保证终端设备的服务质量(quality of service，QoS)。
需要说明的是，这里的上行功率控制包括开环功率控制和闭环功率控制。具体地，开环功率控制是指：对于PRACH，在随机接入时，由于终端设备与基站还没有完成上行同步过程，无法获取基站的指示，所以采用开环功率控制，终端设备根据参数设置计算出发送功率。PUSCH发送随机接入过程的消息(Msg3)时也采用了开环功率控制。闭环功率控制是指：对于PUSCH、PUCCH、SRS，基站根据上行信道质量情况进行闭环功率控制，计算功率调整量，并发送给终端设备，终端设备根据功率调整量计算出上行的功率值。
可选地，上行功率控制主要包括：PRACH功率控制、PUSCH功率控制、PUCCH功率控制、SRS功率控制。
可选地，在进行上行功率控制后，终端设备可以得到发送功率，然后使用该发送功率减去前文对应的最大发送功率，可以得到功率余量。其中，功率余量的计算方法可以参考标准3GPP中36.213的描述。与现有协议不同的是，本申请实施例是根据上行子载波或者频率段进行功率余量计算的，粒度会更细。
本申请还提供了另一实施例，提供了一种适用于多连接通信系统中功率余量信息的上报格式。图9示出了根据本申请另一实施例的上行数据的传输方法900的示意性流程图。所述方法900应用于多连接通信系统，所述多连接通信系统包括多个MAC实体。如图9所示，所述方法900包括：
S901，终端设备接收来自基站的上行授权；
S902，所述终端设备使用多个MAC实体的上报方式向基站发送报告，所述报告包括每个MAC实体对应的子报告，其中，每个MAC实体对应的子报告是按序排列的。
其中，多个MAC实体可以理解为多个小区组CG。
具体而言，针对多连接通信系统，本申请提出了一种新的PHR上报格式，可以将多个MAC实体对应的子报告按序堆叠在一起上报，从而形成新的PHR上报格式，扩展性更好，而现有技术是不支持多连接通信系统的PHR上报的。例如，图10是根据本申请另一实施例的一个例子的示意图。如图10所示，N个MAC实体的PHR的子报告可以按序排列，堆叠在一起上报。
可选地，各个MAC实体对应的子报告可以采用相同或不同的上报格式，对此不作限定。
可选地，作为一个实施例，所述上报格式包括多个位图信息，所述多个位图信息位于所述多个MAC实体对应的子报告前，其中，每个位图信息用于指示每个MAC实体的服务小区对应的功率余量的信息。也就是说，进一步地，可以把多个MAC实体的位图信息，放置在功率余量的信息前。可选地，每个位图信息可以指示小区的序号或小区对应的功率余量信息。如图11所示，N个位图信息放置在N个MAC实体对应的PH值前。MAC实 体1对应的位图信息(bitmap for MAC实体1)，MAC实体2对应的位图信息(bitmap for MAC实体2)，…MAC实体N对应的位图信息(bitmap for MAC实体N)，以及，MAC实体1对应的PH值集合(lists of PHs for MAC实体1)，MAC实体2对应的PH值集合(lists of PHs for MAC实体2)，…MAC实体N对应的PH值集合(lists of PHs for MAC实体N)，堆叠在一起上报。
或者，所述报告包括第一位图信息，所述第一位图信息位于所述多个MAC实体对应的子报告前，其中，所述第一位图信息用于指示所述多个MAC实体对应的功率余量的信息。也就是说，进一步地，可以采用一个位图信息(比如第一位图信息)指示多个MAC实体的功率余量的信息，并放置在多个MAC实体的功率余量的信息前。可选地，第一位图信息也可以指示小区的序号。如图12所示，一个位图信息放置在N个MAC实体对应的PH值前。MAC实体1-N对应的位图信息(bitmap for MAC实体1-N)，以及，MAC实体1对应的PH值集合(lists of PHs for MAC实体1)，MAC实体2对应的PH值集合(lists of PHs for MAC实体2)，…MAC实体N对应的PH值集合(lists of PHs for MAC实体N)，堆叠在一起上报。
可选地，在图11和图12中对各个MAC实体的PH值的上报顺序不作限定，可以按照上行子载波或者BWP的序号升序排列，或者降序排列，或者按照其他规律排列。
或者，如果所述终端设备与所述基站在同一MAC实体，所述报告包括第二位图信息，所述第二位图信息用于指示格式1/3对应的PH集合。
或者，如果所述终端设备与所述基站不在同一MAC实体，所述报告包括所述第三位图信息和第四位图信息，其中，所述第三位图信息用于指示所述终端设备所在的MAC实体中格式1/3对应的PH集合，所述第四位图信息用于指示所述终端设备所在的MAC实体中格式2对应的PH集合。
具体而言，在多连接场景中，如果终端设备与基站在同一个MAC实体，则可以使用一个比特位图(比如第二位图信息)来指示格式1/3对应的PH集合；如果终端设备与基站不在同一个MAC实体，则需要使用两个比特位图来指示格式1/3对应的PH集合和格式2对应的PH集合，比如第三位图信息指示格式1/3对应的PH集合，第四位图信息指示格式2对应的PH集合。例如，图13示出了根据本申请另一实施例的另一个例子的示意图，如图13所示，MAC实体1和主小区组(master cell group，MCG)是同侧，与第二小区组(secondary cell group，SCG)是异侧。MAC实体2和SCG是同侧，与MCG是异侧。MAC实体1在向MCG上报PHR时，只需要用一个位图信息指示格式1/3对应的PH集合(即格式1/3PH位图信息)；而MAC实体2在向MCG上报PHR时，不仅需要用一个位图信息指示格式1/3对应的PH集合(即格式1/3PH位图信息)，还需要另一个位图信息指示格式2对应的PH集合(即格式2PH位图信息)。同理，MAC实体1在向SCG上报PHR时，不仅需要用一个位图信息指示格式1/3对应的PH集合(即格式1/3PH位图信息)，还需要另一个位图信息指示格式2对应的PH集合(即格式2PH位图信息)；而MAC实体2在向SCG上报PHR时，只需要用一个位图信息指示格式1/3对应的PH集合(即格式1/3PH位图信息)。
可选地，作为一个实施例，所述多个MAC实体包括LTE版本的MAC实体和高于LTE版本的MAC实体，其中，所述LTE版本的MAC实体根据小区向所述基站上报功率 余量信息，所述高于LTE版本的MAC实体根据上行子载波或频率段向所述基站上报功率余量信息。
具体而言，在多连接通信场景中，可能会存在多个版本的MAC实体，比如LTE版本和高于LTE版本(比如NR)的MAC实体，此时，LTE版本的MAC实体可以小区为单位向基站上报功率余量信息，而高于LTE版本的MAC实体可以上行子载波或频率段为单位向基站上报功率余量信息。
可选地，如果一个MAC实体的服务小区中配置了上行子载波，但是没有配置BWP，而另一个MAC实体的小区中配置了BWP并且已经激活。此时，配置了上行子载波的MAC实体还是以上行子载波为单位上报PHR。
可选地，在多连接通信系统中，每个MAC实体只上报本MAC实体的PH值和比该MAC实体版本低的MAC实体的PH值，而不上报比该MAC实体版本高的PH值。
因此，本申请实施例的上行数据的传输方法中提出的上报格式，能够支持多连接通信系统中PHR的上报。
