  • Carrier aggregation is a technology to increase the transmission bandwidth. It aggregates multiple carriers of different frequencies (or the same frequency) into a wider spectrum. At the same time, it can also aggregate some discontinuous spectrum fragments together to achieve the goal of increasing bandwidth. Effect. For example, a carrier bandwidth of 100MHz can only be one carrier. In order to pursue a higher transmission rate, the carrier aggregation technology can be used to establish a connection between multiple carriers and the user equipment UE to provide data transmission. For example, two carriers with a bandwidth of 100MHz are aggregated. After aggregation, a total bandwidth of 200MHz can be obtained. Compared with a single carrier of 100MHz, the speed of data transmission is directly doubled, which improves the use and transmission rate.

具体实施方式
为了便于理解，首先介绍本申请涉及的术语。
1、载波聚合(Carrier Aggregation，CA)
载波聚合是一种增加传输带宽的技术，将多个不同频率(或者相同频率)的载波聚合成一个更宽的频谱，同时也可以把一些不连续的频谱碎片聚合到一起，从而达到提高带宽的效果。例如，一个载波带宽100MHz只得是一个载波。而为了追求更高的传输速率，应用载波聚合技术可以把多个载波一同与用户设备UE建立连接提供数据传输。比如2个100MHz带宽的载波聚合，聚合后即可得到200MHz带宽总量，传输数据的速度相较于单100MHz的载波直接翻倍，提高了使用和传输速率。
为了更好的理解本申请实施例公开的一种多载波聚合能力的上报方法，下面首先对本申请实施例适用的通信系统进行描述。
请参见图1，图1为本申请实施例提供的一种通信系统的架构示意图。该通信系统可包括但不限于一个网络设备和一个终端设备，图1所示的设备数量和形态仅用于举例并不构成对本申请实施例的限定，实际应用中可以包括两个或两个以上的网络设备，两个或两个以上的终端设备。图1所示的通信系统以包括一个网络设备101和一个终端设备102为例。
需要说明的是，本申请实施例的技术方案可以应用于各种通信系统。例如：长期演进(long term evolution，LTE)系统、第五代(5th generation，5G)移动通信系统、5G新空口(new radio，NR)系统，或者其他未来的新型移动通信系统等。还需要说明的是，本申请实施例中的侧链路还可以称为侧行链路或直通链路。
本申请实施例中的网络设备101是网络侧的一种用于发射或接收信号的实体。例如，网络设备101可以为演进型基站(evolved NodeB，eNB)、收发点(transmission reception point，TRP)、NR系统中的下一代基站(next generation NodeB，gNB)、其他未来移动通信系统中的基站或无线保真(wireless fidelity，WiFi)系统中的接入节点等。本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。本申请实施例提供的网络设备可以是由集中单元(central unit，CU)与分布式单元(distributed unit，DU)组成的，其中，CU也可以称为控制单元(control unit)，采用CU-DU的结构可以将网络设备，例如基站的协议层拆分开，部分协议层的功能放在CU集中控制，剩下部分或全部协议层的功能分布在DU中，由CU集中控制DU。
本申请实施例中的终端设备102是用户侧的一种用于接收或发射信号的实体，如手机。终端设备也可以称为终端设备(terminal)、用户设备(user equipment，UE)、移动台(mobile station，MS)、移动终端设备(mobile terminal，MT)等。终端设备可以是具备通信功能的汽车、智能汽车、手机(mobile  phone)、穿戴式设备、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)中的无线终端设备、无人驾驶(self-driving)中的无线终端设备、远程手术(remote mediCAl surgery)中的无线终端设备、智能电网(smart grid)中的无线终端设备、运输安全(transportation safety)中的无线终端设备、智慧城市(smart city)中的无线终端设备、智慧家庭(smart home)中的无线终端设备等等。本申请的实施例对终端设备所采用的具体技术和具体设备形态不做限定。
随着移动通信技术的发展，为了满足更高的速率的要求，高频、大带宽、大规模天线技术和多载波聚合越来越成为无线通信技术发展的趋势。
多载波聚合技术在第五代通信系统也被广泛使用，主要分为频带内的连续载波聚合、频带内的非连续载波聚合和频带间的载波聚合。对于频带内的连续载波聚合，RAN4定义了连续载波聚合的聚合带宽等级。为了满足不同的应用场景和不同的终端能力，RAN4进一步定义了不同的回退组(Fallback group，FBG)。
网络侧会给所有终端设备默认配置一个支持CA的载波数量，比如8个。但是有些终端设备在本身终端能力的限制下不能支持这么多载波的聚合，那终端设备需要选取支持其他CA的载波数量，可以根据所述回退组获取支持其他CA的载波数量。

表1
表1为针对毫米波FR2连续载波聚合定义的聚合带宽等级和相应的回退组，带宽聚合等级NR CA  bandwidth class是按照载波聚合后支持的总带宽的范围，表1中定义了一些带宽聚合等级的代号(A、B、C、D、E、F、G、H、I、J、K、L、M、O、P、Q)，NR CA bandwidth class和按照NR CA bandwidth class进行载波聚合后的总带宽范围Aggregated channel bandwidth一一对应。Number of contiguous CC为实现Aggregated channel bandwidth对应使用的载波个数。因为每个载波的带宽可以不同，所以同样的总带宽下，可能对应不同的载波个数。回退组(Fallback group，FBG)为NR CA bandwidth class对应的回退组。FR2回退组的定义是基于所能支持的最大信道带宽定义的且每个聚合等级中只能有一个载波带宽小于所支持的最大信道带宽。例如：FBG 1的带宽聚合等级是针对单载波所能支持的最大信道带宽为400MHz定义的，FBG 2的带宽聚合等级是针对单载波所能支持的最大信道带宽为200MHz定义的，FBG 3的带宽聚合等级是针对单载波所能支持的最大信道带宽为100MHz定义的。NR CA bandwidth class A对应的回退组可以为FBG 1或FBG 2或FBG 3或FBG 4，与其他NR CA bandwidth class对应的回退组不同。
上述FR2的连续载波聚合的聚合带宽等级仅要求终端必须能够回退到同一回退组中的较低阶聚合带宽等级，对于不同回退组之间不强制要求回退。
Figure PCTCN2021123640-appb-000002
表2
如表2所示，随着终端能力的不断增强，运营商提出了增加更大聚合带宽等级，如在回退组FBG2中增加最大聚合能力分别为1000MHz,1200MHz,1400MHz和1600MHz的聚合带宽等级R、S、T、U。
Figure PCTCN2021123640-appb-000003
表3
如表3所示，目前RAN4正在讨论在FR2中引入4个跨回退组之间的连续载波聚合的聚合带宽等级Intra-band contiguous CA bandwidth class，例如由回退组3中的聚合带宽等级M(8个100MHz载波)和回退组2中的聚合带宽等级A(1个200MHz载波)组合形成聚合带宽等级MA(9个连续载波聚合带宽为1000MHz)。还有其他可能的聚合带宽等级MD，ME，MF等。连续载波聚合的聚合带宽等级MA、MD、ME、MF对应的回退组均为FBG2-3。
目前频带内的连续载波聚合的聚合带宽等级是在以下信息元素(Information Element，IE)中通过枚举的方式进行上报的。
Figure PCTCN2021123640-appb-000004
Figure PCTCN2021123640-appb-000005
NR载波聚合带宽等级信令IE CA-BandwidthClassNR预留了扩展位，可在当前IE CA-BandwidthClassNR内直接扩展新的聚合带宽组合R，S，T，U，MA，MD，ME，MF。通过上述IEs来上报UE支持新的聚合带宽等级。
随着终端能力的不断增强，运营商提出了增加更大聚合带宽等级，如在回退组FBG2中增加最大聚合能力分别为1000MHz,1200MHz,1400MHz和1600MHz的聚合带宽等级。并进一步提出了跨回退组之间的连续载波聚合的聚合带宽等级的需求。
如果在现有IE CA-BandwidthClassNR内直接扩展新的聚合带宽组合，会导致网络后向兼容的问题。例如终端通过信令supportedBandCombinationList中的IE CA-BandwidthClassNR上报其支持聚合带宽R，S，T，U时，但是有些网络无法识别IE CA-BandwidthClassNR中新扩展的聚合带宽等级，导致网络无法给终端配置相应的聚合带宽。
具体来说，如果在现有载波聚合带宽等级信令IE CA-BandwidthClassNR内直接扩展新的聚合带宽等级R，S，T，U，MA，MD，ME，MF，可能会导致网络后向兼容的问题。例如，当终端通过支持频段组合列表SupportedBandCombinationList中的载波聚合带宽等级信令IE CA-BandwidthClassNR上报其支持聚合带宽等级R，S，T，U时，如果网络侧设备无法识别IE CA-BandwidthClassNR中新扩展的聚合带 宽等级R，S，T，U，导致网络侧设备无法给终端设备配置相应的聚合带宽。
可以理解的是，本申请实施例描述的通信系统是为了更加清楚的说明本申请实施例的技术方案，并不构成对于本申请实施例提供的技术方案的限定，本领域普通技术人员可知，随着系统架构的演变和新业务场景的出现，本申请实施例提供的技术方案对于类似的技术问题，同样适用。
下面结合附图对本申请所提供的多载波聚合能力的上报方法及其装置进行详细地介绍。
请参见图2，图2是本申请实施例提供的一种多载波聚合能力的获取方法的流程示意图。所述方法由网络侧设备执行。如图2所示，该方法可以包括但不限于如下步骤：
步骤S201：通过第一信令向网络侧设备上报终端设备支持的聚合带宽等级或聚合能力信息，以及通过第二信令向所述网络侧设备上报终端设备支持的聚合带宽等级；其中所述第二信令上报的聚合带宽等级是所述第一信令上报的聚合带宽等级的回退聚合带宽等级。
在一种可能的实施例中，终端设备支持聚合带宽等级R,S,T,U中的一种或多种，所述终端设备向网络侧设备发送第一信令和第二信令。所述第一信令为supportedBandCombinationList-v17xy，其中，后缀-v17xy为可选，其可以根据不同的Release改变(例如在Release18中可能称为v18xy)；且其中的xy为序号；下同，不再赘述。通过所述supportedBandCombinationList-v17xy中的CA-BandwidthClassDL-NR-v17xy上报所述终端设备下行支持R,S,T,U中的一种或多种聚合带宽等级；或通过所述supportedBandCombinationList-v17xy中的CA-BandwidthClassUL-NR-v17xy上报所述终端设备上行支持R,S,T,U中任意一个或任意多个聚合带宽等级；其中后缀-v17xy为可选，其可以根据不同的Release改变；且其中的xy为序号；下同，不再赘述。所述第二信令为supportedBandCombinationList。通过所述supportedBandCombinationList中的CA-BandwidthClassDL-NR上报所述终端设备下行支持的聚合带宽等级F；或通过所述supportedBandCombinationList中的CA-BandwidthClassUL-NR上报所述终端设备上行支持个聚合带宽等级F。
在一种可能的实施例中，终端设备支持聚合带宽等级MA，MD，ME，MF，所述终端设备向网络侧设备发送第一信令和第二信令。所述第一信令为supportedBandCombinationList-v17xy，其中，xy为序号。通过所述supportedBandCombinationList-v17xy中的CA-BandwidthClassDL-NR-v17xy上报所述终端设备下行支持MA，MD，ME，MF中任一个或任意多个聚合带宽等级；或通过所述supportedBandCombinationList-v17xy中的CA-BandwidthClassUL-NR-v17xy上报所述终端设备上行支持MA，MD，ME，MF中任一个或任意多个聚合带宽等级。所述第二信令为supportedBandCombinationList。通过所述supportedBandCombinationList中的CA-BandwidthClassDL-NR上报所述终端设备下行支持的聚合带宽等级M或A；或通过所述supportedBandCombinationList中的CA-BandwidthClassUL-NR上报所述终端设备上行支持个聚合带宽等级M或A。

当然，本申请实施例中，第一信令和第二信令可以为不同的信令，或，在另一种可能的实施方式中，第一信令和第二信令可以为同一个信令的不同字段。本申请实施例中，所述网络侧设备可能由于版本落后，不能识别新增的聚合带宽等级。为了避免网络侧设备无法识别新扩展的聚合带宽等级，导致网络侧设备无法给终端设备配置相应的聚合带宽。通过所述第二信令上报的聚合带宽等级是所述第一信令上报的聚合带宽等级的回退聚合带宽等级。如表2所示，在一种可能的实施例中，所述第一信令上报的聚合带宽等级为以下的至少一种：R或S或T或U，则所述第二信令上报的聚合带宽等级为FBG2。
