为了更好的理解本申请实施例公开的频带分组方法及装置，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。
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)、传输点(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(terminal)也可以称为用户设备(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。
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。
为了聚合使用连续或非连续的带宽，LTE/5G NR采用了载波聚合(CA，Carrier Aggregation)的方式。一个小区对应一个成员载波(CC，Component Carrier)。为了支持多种多样的业务和不同形态的终端，5G NR引入了部分带宽(BWP，Bandwidth Part)的概念。BWP是一个小区频带内一段连续的频带，NR通过BWP自适应灵活调整终端设备接收和发送带宽的大小，使得终端设备接收和发送带宽不需要与小区自身的带宽一样大，例如：1)终端设备处于低活动期时，基站可以通过高层信令或下行控制信息(DCI，Downlink Control Information)指示缩小终端设备的使用带宽(即使用小带宽的BWP)，如此可节省终端设备的功率；2)终端设备所需的吞吐量比较大时，基站可以通过高层信令或DCI指示增加终端设备的使用带宽(即使用大带宽的BWP)，如此可提高终端设备的数据速率；3)基站可以指示终端设备使用不同的BWP，终端设备所使用带宽的位置可在频域中移动，因此增加了调度的灵活性；4)不同的BWP可以使用不同的子载波间隔，通过选择不同子载波间隔的BWP，能够更好地支持不同的业务。
然而，CC的配置和激活基于高层信令实现，由此带来了配置以及激活/去激活时延大、信令开销大的问题。为此，可设计一个小区对应多个不连续频带或一个具有较大频率范围的频带。
本公开提出了一种频带分组方法及装置，能够将小区的多个不连续频带或具有较大频率范围的频带划分成多个组，以便终端设备能够基于分组后的频带执行各种操作。
下面结合附图对本申请所提供的频带分组方法及装置进行详细地介绍。
图2示出了根据本公开实施例的一种频带分组方法的流程示意图。如图2所示，该方法可由网络设备执行，且包括以下步骤。
步骤S201，向终端设备发送频带分组信息，其中，频带分组信息用于指示将终端设备的服务小区的一个或多个可接入频带划分为多个频带组的分组方式。
在本实施例中，当前为所述终端设备提供服务的服务小区可以对应多个不连续可接入频带或者对应一个具有较大频率范围的可接入频带，在这种情况下，通过对一个或多个可接入频带进行分组管理是有利的。为此，网络设备可以向终端设备发送指示对该终端设备的服务小区的一个或多个可接入频带进行划分的分组方式的频带分组信息。终端设备根据该频带分组信息将一个或多个可接入频带划分成多个频带组。
根据本发明实施例的频带分组方法，网络设备向终端设备发送用于指示将终端设备的服务小区的一个或多个可接入频带划分为多个频带组的分组方式的频带分组信息，从而终端设备能够将服务小区的一个或多个可接入频带划分为多个频带组，以便基于分组后的频带执行各种操作。
在一些实施例中，每个频带组包括多个子频带Subband或多个部分带宽BWP。
在本实施例中，在对一个或多个可接入频带进行分组时，可以以子频带为单位进行分组或者以BWP为单位进行分组，使得分组后的每个频带组包括多个子频带或多个BWP。
在一些实施例中，网络设备通过以下之一将频带分组信息发送给终端设备：无线资源控制(RRC，Radio Resource Control)信令；媒体访问控制(MAC，Media Access Control)信令；以及下行控制信息(DCI)。
图3示出了根据本公开实施例的一种频带分组方法的流程示意图，如图3所示，该方法可由网络设备执行，且包括以下步骤。
步骤S301，基于以下信息中的至少一种确定分组方式：每个可接入频带的频率范围；多个可接入频带之间的频率间隔；以及与多个可接入频带对应的多个发送接收点之间的距离。
网络设备可以基于每个可接入频带的频率范围、多个可接入频带之间的频率间隔、和/或与多个可接入频带对应的多个发送接收点之间的距离。
例如，若小区对应对应一个具有较大频率范围的可接入频带，网络设备可以基于该可接入频带的频率范围来确定分组方式。例如，如果该可接入频带的频率范围为2.4～5GHz时，该可接入频带的频率范围过大，网络设备基于该频率范围可将其划分成多组，例如，划分成3组：<2.4～3.3GHz>，<3.3～4.2GHz>，<4.2GHz～5GHz>。
又如，若小区对应多个可接入频带，网络设备可以基于该多个可接入频带的频率间隔来确定分组方式。例如，如果该多个可接入频带分别为：2.4～2.8GHz(可接入频带1)、3～3.3GHz(可接入频带2)、3.8～4.2GHz(可接入频带3)以及4.4GHz～5GHz(可接入频带4)，例如，网络设备可以基于每个频带的中间频率之间的频率间隔来确定分组方式，即，可接入频带1-可接入频带4之间的频率间隔分别为：0.55、0.85、0.7，网络设备例如可以将频率间隔小于0.6的两个可接入频带划分成一组，由此将上述4个可接入频带划分为3组：<2.4～2.8GHz,3～3.3GHz>、<3.8～4.2GHz>、<4.4GHz～5GHz>。
应当注意，上述两个可接入频带之间的频率间隔也可以为两个可接入频带之间的上限频率之间的间隔、下限频率之间的间隔、较低频带的上限频率与较高频带的下限频率之间的间隔等等，本申请对此并不做限制。
又如，若小区对应多个可接入频带，网络设备可以基于该多个可接入频带对应的多个发送接收点之间的距离来确定分组方式。例如，如果4个可接入频带可接入频带1-可接入频带4分别对应发送接收点TRP1-TRP4，其中TRP1和TRP2共址或准共址、TRP2和TRP3间隔第一距离、TRP3和TRP4间隔第二距离、TRP2和TRP4间隔第三距离，网络设备可以例如将TRP之间的间隔距离小于某个阈值的两个TRP对应的两个可接入频带划分成一组，即，如果第一距离小于该阈值，而第二距离和第三距离均大于该阈值，则上述4个可接入频带可被划分成两组：<可接入频带1、可接入频带2、可接入频带3>、<可接入频带4>。
又如，网络设备可以综合考虑每个可接入频带的频率范围、多个可接入频带之间的频率间隔、和/或与多个可接入频带对应的多个发送接收点之间的距离等信息来确定分组方式。
步骤S302，向终端设备发送频带分组信息，其中，频带分组信息用于指示将终端设备的服务小区的一个或多个可接入频带划分为多个频带组的分组方式。
关于上述步骤S302的详细描述，可以参考关于步骤S201的相关描述，在此不再赘诉。
根据本发明实施例的频带分组方法，网络设备可以基于每个可接入频带的频率范围、多个可接入频带之间的频率间隔、和/或与多个可接入频带对应的多个发送接收点之间的距离等来确定分组方式，从而能够将频率间隔较小或对应发送接收点距离较近的多个可接入频带划分成一组。
在一些实施例中，每个频带组包括多个子频带Subband或多个部分带宽BWP。
在对一个或多个可接入频带进行分组时，可以以子频带为单位进行分组或者以BWP为单位进行分组，使得分组后的每个频带组包括多个子频带或多个BWP。
在一些实施例中，网络设备通过以下之一将频带分组信息发送给终端设备：无线资源控制(RRC，Radio Resource Control)信令；媒体访问控制(MAC，Media Access Control)信令；以及下行控制信息(DCI)。
图4示出了根据本公开实施例的一种频带分组方法的流程示意图。如图4所示，该方法可由终端设备执行，且包括以下步骤。
步骤S401，接收网络设备发送的频带分组信息，其中，频带分组信息用于指示将终端设备的服务小区的一个或多个可接入频带划分为多个频带组的分组方式。
在本实施例中，当前为所述终端设备提供服务的服务小区可以对应多个不连续可接入频带或者对应一个具有较大频率范围的可接入频带，在这种情况下，通过对一个或多个可接入频带进行分组管理是有利的。为此，网络设备可以向终端设备发送指示对该终端设备的服务小区的一个或多个可接入频带进行划分的分组方式的频带分组信息。
步骤S402，基于分组方式将服务小区的一个或多个可接入频带划分成多个频带组。
终端设备在从网络设备接收到频带分组信息后，可以根据该频带分组信息所指示的分组方式将一个或多个可接入频带划分成多个频带组。
根据本发明实施例的频带分组方法，网络设备向终端设备发送用于指示将终端设备的服务小区的一个或多个可接入频带划分为多个频带组的分组方式的频带分组信息，从而终端设备能够将服务小区的一个或多个可接入频带划分为多个频带组，以便基于分组后的频带执行各种操作。
在一些实施例中，每个频带组包括多个子频带Subband或多个部分带宽BWP。
在本实施例中，在对一个或多个可接入频带进行分组时，可以以子频带为单位进行分组或者以BWP为单位进行分组，使得分组后的每个频带组包括多个子频带或多个BWP。
在一些实施例中，终端设备通过以下之一从网络设备接收频带分组信息：无线资源控制(RRC，Radio Resource Control)信令；媒体访问控制(MAC，Media Access Control)信令；以及下行控制信息(DCI)。
在一些实施例中，任一子频带或BWP的参考信号能够被子频带或BWP所属频带组内的其他子频带或BWP共享。
由于被划分成一组的频带例如或者频率间隔较小或者对应发送接收点距离较近，同属一组的Subband或BWP可以共享参考信号。例如，一个频带组包括三个子频带：Subband1、Subband 2和Subband 3，如果已经针对Subband 1获得参考信号，则该参考信号可被用于Subband 2和Subband 3上实现各种操作。
在一些实施例中，参考信号被共享用于执行以下中至少一种操作：时频同步；路径损耗估计；无线链路检测(RLM，Radio Link Monitor)；无线资源管理(RRM，Radio Resource Management)测量；以及波束测量上报。
如上示例所述，Subband 1的参考信号可被用于Subband 2和Subband 3上，例如用于实现时频同步；路径损耗估计；RLM；RRM测量；以及波束测量上报等。
在一些实施例中，同一频带组内的所有子频带或BWP共用相同波束或定时提前量(TA，Time Advance)。
类似的，由于被划分成一组的频带例如或者频率间隔较小或者对应发送接收点距离较近，同属一组的子频带Subband或BWP可以共用相同波束或TA。例如，一个频带组包括三个BWP：BWP 1、BWP 2和BWP 3，则该3个BWP 1-BWP 3可以使用相同的接收波束和发送波束，并且可以使用相同的TA。
上述本申请提供的实施例中，分别从网络设备、用户设备的角度对本申请实施例提供的方法进行了介绍。为了实现上述本申请实施例提供的方法中的各功能，网络设备和用户设备可以包括硬件结构、软件模块，以硬件结构、软件模块、或硬件结构加软件模块的形式来实现上述各功能。上述各功能中的某个功能可以以硬件结构、软件模块、或者硬件结构加软件模块的方式来执行
