具体实施方式
为使本领域的技术人员更好地理解本公开实施例的技术方案，下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
在本公开的描述中，除非另有说明，“/”表示“或”的意思，例如，A/B可以表示A或B。本文中的“和/或”仅仅是一种描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：仅A，仅B，以及A和B。此外，“至少一个”是指一个或多个，“多个”是指两个或两个以上。“第一”、“第二”等表述并不对数量和执行次序进行限定，并且“第一”、“第二”等表述也并不限定一定不同。
需要说明的是，本公开中，“示例性地”或者“例如”等词用于表示作例子、例证或说明。本公开中被描述为“示例性地”或者“例如”的任何实施例或设计方案不应被解释为比其他实施例或设计方案更优选或更具优势。确切而言，使用“示例性地”或者“例如”等词旨在以具体方式呈现相关概念。
第四代移动通信技术(the 4th generation mobile communication technology，4G)高级长期演进(Long-Term Evolution Advance，LTE-Advance)和第五代移动通信科技(the 5th generation mobile communication technology，5G)面临越来越多的需求。基于当前的发展趋势，4G和5G系统正在开发对增强型移动宽带(enhanced mobile broadband，eMBB)、超可靠低延迟通信(ultra-reliable low-latency communication URLLC)和大规模机器类型通信(massive machine type communication，mMTC)功能的支持。载波聚合(carrier aggregation，CA)可以用作4G和5G以及其他通信系统对小区覆盖和用户速率提升的有效手段。
在目前移动通信系统的CA技术中，随着信道状态变化，为了匹配当前传输业务，网络侧只能通过无线资源控制层(Radio Resource Control，RRC)配置以及重新配置载波组合，通过媒体接入控制-控制单元(Medium Access Control-Control Element，MAC-CE)指示辅载波/辅小区(Secondary Cell，Scell)激活或者去激活。这些通过半静态通知方式不仅用时近几十毫秒时间，而且不能灵活改变载波组合，进而不能匹配实际的信道状态变化。
鉴于此，本公开提出一种载波配置方法，通过第一节点通过接收第二节点发送的配置信令，配置信令用于确定载波组合的配置信息；第一节点和第二节点基于载波组合的配置信息进行多载波通信。这样，基于不同的信道状态，第二节点可以及时向第一节点发送的不同的配置信令，以便于第一节点和第二节点基于不同的配置信令所确定的不同的载波组合的配置信息进行多载波通信，实现了动态配置载波组合以匹配实际的信道状态，提高了通信效率。
本公开实施例提供的载波配置方法，可以应用于多种通信制式的系统。例如，本公开实施例所提供的载波配置方法可以适用的系统包括但不限于LTE系统、基于LTE演进的各种版本、5G系统等通信系统。此外，本公开实施例所提供的系统消息的发送、接收方法，还可以适用于面向未来的通信系统(例如，6G通信系统)等。
本公开实施例中移动通信网络(包括但不限于3G、4G、5G以及未来移动通信网络)的网络架构可以至少包括第一通信节点和第二通信节点。应当理解的是，在本示例中，在下行链路中第一通信节点可以是网络侧设备(例如，包括但不限于基站)，第二通信节点可以终端侧设备(例如，包括但不限于终端)。当然， 在上行链路中第一通信节点也可以是终端侧设备，第二通信节点也可以是网络侧设备。在两个通信节点是设备到设备通信中，第一通信节点和第二通信节点都可以是基站或者终端。第一通信节点和第二通信节点可以分别简称第一节点和第二节点。
示例性地，以第一通信节点为终端，第二通信节点为基站为例，如图1所示，为本公开实施例提供的一种通信系统的架构示意图，该通信系统包括终端10和基站20。终端10和基站20的数量可以为一个或多个，此处不对数量进行限定。
在一些实施例中，基站20为终端10提供无线接入服务。一个基站20提供至少一个服务覆盖区域(又可称为小区)。进入该区域的终端10可通过无线信号与基站20通信，以此来接收基站20提供的无线接入服务。
在一些实施例中，基站可以是长期演进(long term evolution，LTE)、长期演进增强(long term evolution advanced，LTEA)中的基站或演进型基站(evolutional node B，eNB或eNodeB)、5G网络中的基站设备、或者未来通信系统中的基站等，基站可以包括各种宏基站、微基站、家庭基站、无线拉远设备、可重构智能表面(reconfigurable intelligent surfaces，RISs)、路由器、中继、TRP、无线保真(wireless fidelity，WIFI)设备等各种网络侧设备。
在一些实施例中，终端可以是一种具有无线收发功能的设备。终端可以是手机(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、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)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。本公开的实施例对应用场景不做限定。终端有时也可以称为用户，用户设备(User Equipment，UE)、接入终端、UE单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等，本公开实施例对此并不限定。
本公开的实施例的应用场景不做限定。本公开实施例描述的系统架构以及业务场景是为了更加清楚的说明本公开实施例的技术方案，并不构成对于本公开实施例提供的技术方案的限定，本领域普通技术人员可知，随着网络架构的演变和新业务场景的出现，本公开实施例提供的技术方案对于类似的技术问题，同样适用。
本公开实施例提供一种载波配置方法。如图2所示，该方法包括以下S101-S102。
S101、第一节点向第二节点发送配置信令；相应地，第一节点接收第二节点发送的配置信令。配置信令用于确定载波组合的配置信息。
载波组合还可以有其他名称，例如载波聚合、载波聚合组合(记为CA组合)，本公开对此不进行限制。
在一些实施例中，配置信令包括下行控制信息(Downlink Control Information，DCI)。由于DCI为物理层信令，通过DCI来配置载波组合，相比于一些技术中通过RRC信令配置载波组合(也即半静态的配置方式)，配置的时间短，实现了灵活配置不同的载波组合来适应于实际的信道状态。
在一些实施例中，下行控制信息指示不同载波数量的聚合使用。
在一些实施例中，配置信令包括位图，位图包括多个指示位，每个指示位对应一个载波，每个指示位用于指示指示位对应的载波是否属于载波组合。
示例性地，如图3所示，假设网络侧配置三个载波，分别是载波1、载波2和载波3。基站向终端发送配置信令，配置信令包括的位图有三个指示位分别为第一指示位、第二指示位、第三指示位，这三个指示位 依次对应载波1、载波2、载波3。假设指示位为“0”，则该指示位对应的载波不属于基站给该终端配置的载波组合；指示位为“1”，则该指示位对应的载波属于基站给该终端配置的载波组合。例如在T1时刻基站向终端发送的DCI中的位图为“110”，则表示载波1和载波2属于基站给该终端配置的载波组合，载波3不属于基站给该终端配置的载波组合。
在一些实施例中，基于载波组合的配置信息，确定第一节点待监测的载波。
在一些实施例中，基于载波组合的配置信息，确定第一节点待监测的载波包括以下至少一项：
基于第一节点支持监测的载波数量与载波组合的配置信息对应的载波数量进行比较，确定第一节点待监测的载波；
基于第一节点支持监测的载波数量与在预设时间段内接收到的配置信令确定的载波组合的配置信息对应的载波数量进行比较，确定第一节点待监测的载波；
在配置信令确定的载波组合的配置信息对应的载波数量等于网络侧配置的所有载波对应的载波数量的情况下，基于第一节点支持监测的载波数量与所述网络侧配置的所有载波对应的载波数量之间进行比较，确定所述第一节点待监测的载波。
在一些实施例中，配置信令所确定载波组合的数量为一个或多个。在确定的载波组合的数量为一个的情况下，基于第一节点支持监测的载波数量与该载波组合对应的载波数量进行比较，确定第一节点待监测的载波；在确定的载波组合的数量为多个的情况下，基于第一节点支持监测的载波数量与该多个载波组合中的一个或多个载波组合对应的载波数量进行比较，确定第一节点待监测的载波。
示例性地，继续参考图3，配置信令所确定载波组合包括载波组合1和载波组合2。载波组合1包括载波2和载波3，载波组合2包括载波1和载波3。可以基于第一节点支持监测的载波数量与载波组合1包含的所有载波数量进行比较，确定第一节点待监测的载波。也可以基于第一节点支持监测的载波数量与载波组合2包含的所有载波数量进行比较，确定第一节点待监测的载波。还可以基于第一节点支持监测的载波数量与载波组合1和载波组合2这两个载波组合所包含的载波数量进行比较，确定第一节点待监测的载波。一些确定方法可以结合实际的通信场景进行确定，或者预先配置。
又一示例性地，继续参考图3，在T1到T2时间段内，接收到的配置信令确定的载波组合包括载波1和载波2，对应的载波数量2；在T2到T3时间段内，接收到的配置信令确定的载波组合包括载波1、载波2和载波3，对应的载波数量3；在T3到T4时间段内，接收到的配置信令确定的载波组合包括载波1和载波3，对应的载波数量2。在T1到T2时间段内第一节点待监测的载波可以基于在T1到T2时间段内接收到的配置信令确定的载波组合的配置信息对应的载波数量和第一节点支持监测的载波数量进行比较来确定。在T2到T3时间段内第一节点待监测的载波可以基于在T2到T3时间段内接收到的配置信令确定的载波组合的配置信息对应的载波数量和第一节点支持监测的载波数量进行比较来确定。T3到T4时间段内以及其他时间段第一节点待监测的载波的确定也采用上述类似方法，此处不再赘述。
又一示例性地，继续参考图3，网络侧配置的所有载波对应的载波数量为3，分别是载波1、载波2和载波3。配置信令确定的载波组合的配置信息对应的载波也为载波1、载波2和载波3，配置信令确定的载波组合的配置信息对应的载波数量等于网络侧配置的所有载波对应的载波数量。此时可以基于第一节点支持监测的载波数量与网络侧配置的所有载波对应的载波数量之间进行比较，确定第一节点待监测的载波。
在第一节点支持监测的载波数量未知的情况下，第一节点待监测的载波可以将实施例的方法进行结合来确定。
可以理解的是，在一些技术中，在半静态配置载波组合时，第一节点待监测的载波是通过第一节点支持 监测的载波数量与网络侧半静态配置的载波组合所包括的载波数量进行比较来确定的。当第一节点支持监测的载波数量等于或者不等于网络侧半静态配置的载波组合所包括的载波数量时，标准中有明确规定第一节点如何选择待监测的载波。由于本公开是动态配置载波组合，通过这些技术来确定第一节点待监测的载波会出现较大误差，还会产生较大的功耗。所以本公开基于配置信令所确定的载波组合的配置信息，确定第一节点待监测的载波，通过第一节点支持监测的载波数量与动态配置的载波数量进行比较，实现在动态配置载波组合时及时准确地确定出第一节点待监测的载波。
在一些实施例中，基于载波组合的配置信息，确定HARQ码本的大小。
在一些实施例中，基于载波组合的配置信息，确定HARQ码本大小包括以下至少一项：
基于载波组合的配置信息对应的载波数量，确定HARQ码本的大小；
基于在预设时间段内接收到的配置信令确定的载波组合的配置信息对应的载波数量，确定HARQ码本的大小；
在配置信令确定的载波组合的配置信息对应的载波数量等于网络侧配置的所有载波对应的载波数量的情况下，基于网络侧配置的所有载波对应的载波数量，确定HARQ码本的大小。
可以理解的是，在一些技术中指示信道传输是否正确的混合自动重传(hybrid automatic repeat request，HARQ)码本包括三种类型，类型1、类型2和类型3。HARQ码本类型1和类型3的码本大小是根据网络侧半静态配置的CA组合(载波组合)包含的载波数量来确定。由于本公开是动态配置载波组合，通过这些技术来确定HARQ码本的大小会出现较大误差，还会产生较大的功耗。所以本公开基于配置信令所确定的载波组合的配置信息，确定第一节点HARQ码本的大小，可以及时准确地确定出HARQ码本的大小。
在一些实施例中，载波组合的配置信息包括频域资源分配信息。
在一些实施例中，频域资源分配信息的确定方式包括以下至少一项：
基于载波组合中所有辅载波合并而成的频域资源，配置频域资源分配信息；
基于载波组合图样中所有辅载波合并而成的频域资源，配置频域资源分配信息。
在一些实施例中，载波组合图样根据半静态信令配置。
示例性地，联合单个载波和多个载波协作的调度方式。将多个辅载波配置成一个超级单载波，频域资源就是该超级单载波内多个辅载波的频域资源之和。调度信息即频域资源分配(frequency domain resource allocation，FDRA)由主载波通过DCI动态指示的方式来发送。如图3所示，载波2和载波3组成一个超级单载波，频域资源是载波2和载波3的所有频域之和。调度信息由载波1来发送。
示例性地，联合单个载波和多个载波组合图样来协作的调度方式。半静态信令配置一个载波组合图样，频域资源就是该载波组合图样内所有载波的频域资源之和。载波组合图样可以是按照时域来划分，一个周期内或者N个时隙或者N个子帧对应的载波组合图样。N是大于0的整数。进一步地，调度信息包括FDRA是由主载波通过DCI动态指示的方式来发送。
可以理解的是，配置信令所确定的载波组合的配置信息可以结合上述实施例中的不同方法进行确定，或者在不同的时间选择不同实施例的方法进行确定。
在一些实施例中，配置信令还用于确定待监测的物理下行控制信道(physical downlink control channel，PDCCH)。
在一些实施例中，待监测的PDCCH的确定方式包括以下至少一项：
配置信令用于指示载波组合中所有辅载波上待监测的PDCCH；
配置信令用于指示载波组合中所有激活时间段内的辅载波上待监测的PDCCH。
在一些实施例中,在配置信令用于指示载波组合中所有激活时间段内的辅载波上待监测的PDCCH的情况下，第一节点可以只监测辅载波激活状态的起始时刻对应的PDCCH。
在一些实施例中，配置信令承载于载波组合中的主载波上。
当辅载波上配置的PDCCH所占用的资源不用于发送PDCCH时，可以用来发送物理下行共享信道(physical downlink shared channel，PDSCH)或者其他下行信道或下行信号。这样，可以提高资源利用效率。
这样，由于随着移动通信科技的进一步发展，很有可能所有终端都能支持CA技术，但是因为多个载波同时工作，终端功耗很大。通过降低PDCCH的监测频率，可以降低终端功率消耗。
在一些实施例中，配置信令确定的载波组合的配置信息是非连续接收(discontinuous reception，DRX)配置信息。
在一些实施例中，配置信令包括无线资源控制RRC信令。
在一些实施例中，配置信令确定的载波组合中不同载波的不同DRX配置信息包括以下至少一项：
载波组合中辅载波对应的开启持续时间与主载波对应的开启持续时间在时域上对齐；
载波组合中同时处于开启持续时间内的载波的数量不超过预设数量。
在一些实施例中，载波组合中的载波在开启持续时间内处于活动状态，如果在这段时间内没有收到PDCCH，则终端会进入DRX休眠状态，直到下一个“开启持续时间”开始。
示例性地，图4提供一种载波组合的示意图，该载波组合包括载波1、载波2和载波3，载波1、载波2和载波3分别对应不同的DRX图样，即载波1、载波2和载波3在不同时间内的状态可能不同。假设载波1为主载波，载波2和载波3为辅载波，载波2和载波3对应的开启持续时间与载波1对应的开启持续时间在时域上对齐。并且只有在开启持续时间内的终端处于活动状态，会监测PDCCH，当在开启持续时间内没有收到PDCCH，则终端会进入DRX休眠状态。
又一示例性地，图5提供一种载波组合的示意图，该载波组合包括载波1、载波2和载波3，载波1、载波2和载波3分别对应不同的DRX图样，载波组合中同时处于开启持续时间内的载波的数量不超过2个。
这样，由于随着移动通信科技的进一步发展，很有可能所有终端都能支持CA技术，但是因为多个载波同时工作，终端功耗很大。通过设计DRX图样，可以降低终端功率消耗。
在一些实施例中，如图6所示，网络侧一共有4个载波，载波1和载波2是时分双工(time division duplexing，TDD)载波，频域带宽大，载波3和载波4是频分双工(frequency division duplex，FDD)载波，频域带宽小。TDD载波用来传输信道类型1，FDD载波用来传输信道类型2。信道类型1可以是PDCCH、物理上行控制信道(physical uplink control channel，PUCCH)信道，以及除业务信道以外的信道；信道类型2可以是PDSCH、物理上行共享信道(physical uplink shared channel，PUSCH)。网络侧可以按照信道类型来半静态划分CA组合。
S102、第一节点和第二节点基于载波组合的配置信息进行多载波通信。
基于此，基于不同的信道状态，第二节点可以及时向第一节点发送的不同的配置信令，以便于第一节点和第二节点基于不同的配置信令所确定的不同的载波组合的配置信息进行多载波通信，实现了动态配置载波组合以匹配实际的信道状态，提高了通信效率。
目前CA中，定义CA下的UE发射功率是只考虑每个小区和总的载波组合之和的发射功率。当引入动态配置载波组合时，定义终端的发射功率方法可以是以下至少之一：
方法1：每个载波的发射功率。
方法2：每个载波组合的发射功率，即，根据上述实施例提到的载波组合来定义/上报发射功率。
在一些实施例中，目前移动通信系统标准中，定义了同一载频内连续或者非连续载波组合的最大载波数，以及不同载频内载波组合的最大载波数。那么在未来移动通信系统中，多个载波对应的能力可能是以下至少之一：
方法1：最大载波数。无论是同一载频内还是不同载频内的载波数，统一定义最大载波数量。
方法2：不同载频之间的最大载波数。即，同一载频内仅支持单一载波或者不限制同一载频内的载波数量，仅定义不同载频之间的最大载波数量。
进一步地，同一载频内多个载波可以合并为一个载波。
方法3：定义同一载频内最大载波数和不同载频之间最大载波数。
进一步的，同一载频内最大载波数仅针对部分带宽。例如：仅针对新的频段或者太赫兹频段或者仅针对现有频段定义。
上述主要从方法的角度对本公开实施例的方案进行了介绍。下文还示出了一种载波配置装置，载波配置装置用于执行上述任意实施例及其可能的实现方式中的载波配置方法。
可以理解的是，载波配置装置为了实现载波配置方法，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，结合本公开实施例描述的各示例的算法步骤，本公开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公开的范围。
本公开实施例可以根据上述方法实施例分别对载波配置装置进行功能模块的划分，例如，可以对应每一个功能划分每一个功能模块，也可以将两个或两个以上的功能集成在一个功能模块中。上述集成的模块既可以采用硬件的形式实现，也可以采用软件的形式实现。需要说明的是，本公开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。下面以采用对应每一个功能划分每一个功能模块为例进行说明。
