Description

一种载波状态指示方法及设备
本申请要求在2017年9月29日提交中国专利局、申请号为201710938933.9、发明名称为“一种载波状态指示方法及设备”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
本申请涉及无线通信技术领域，特别涉及一种载波状态指示方法及设备。
背景技术
智能终端用户的不断增长，用户业务量和数据吞吐量不断增加，对通信速率提出了更高要求。然而，无线频谱资源短缺，很难找到连续的大带宽供移动通信采用。因此，在长期演进(Long Term Evolution，LTE)通信系统中引入了载波聚合(Carrier Aggregation，CA)技术，把多个连续或不连续的频谱聚合使用，从技术上解决了移动通信对于大带宽的需求，同时也提高了无线频带中零散频谱的利用率。
在第五代(the 5th generation，5G)新无线通信协议(new radio，NR)中，CA也是必要的功能。相比LTE，由于NR中的CA将支持更多场景，因此，需要考虑如何支持NR中载波的激活与去激活。
发明内容
本申请提供一种载波状态指示方法及设备，用以支持NR中载波的激活与去激活。
第一方面，本申请提供一种载波状态指示方法，该方法包括：通信装置基于第一下行载波在第一上行载波上与网络设备进行通信；通信装置接收网络设备发送的载波状态指示信息，载波状态指示信息指示N个网络设备为通信装置提供服务的小区对应的M个载波的载波状态，载波状态包括激活状态和去激活状态，N和M均为正整数；其中，载波状态指示信息指示第一下行载波处于去激活状态，第一上行载波处于激活状态，第一下行载波和第一上行载波均为M个载波中的载波。因此，上述载波状态指示方法能够支持上下行解耦，使上行载波的载波状态不依赖于下行载波的载波状态。
在一种可能的设计中，载波状态指示信息指示M个载波中的第二下行载波处于激活状态；
在通信装置接收网络设备发送的载波状态指示信息后，通信装置基于第二下行载波在第一上行载波上与网络设备进行通信。因此，能够通过重新确定的调度第一上行载波的第二下行载波与网络设备进行通信。

具体实施方式
首先对本申请涉及的技术术语和应用场景进行介绍。
在单载波场景中，以LTE为例，网络设备配置频率资源，该频率资源用于下行传输和上行传输，上行频率资源和下行频率资源之间存在预先定义的对应关系。例如，对于频分双工(frequency domain duplex，FDD)频谱，下行传输和上行传输使用不同的频率资源。对于时分双工(time domain duplex，TDD)频谱，下行传输和上行传输使用相同的频率资源，此时，基于时分复用的方式在相同的频域资源上网络设备进行下行传输和通信装置进行上行传输。
在NR的CA场景中，网络设备为通信装置配置频率资源时，可以配置以下不同类型：
1、频域资源对或频域资源组合。当通信装置需要同时使用上行频域资源和下行频域资源时，网络设备为通信装置配置可以同时使用的上行频域资源和下行频域资源，可以称为频域资源对或频域资源组合，本申请对此不做限定。可以理解的是，该上行频域资源和下行频域资源可以位于相同载波或不同载波。
2、位于频域资源对或频域资源组合中的下行频率资源。
3、补充上行载波(supplementary UL CC，SUL CC)。SUL CC为通信装置用于进行上行传输的频率资源。具体的，该SUL CC为以下至少一种：不位于频域资源对或频域资源组合中、在NR系统中不存在与该补充上行载波具有预定义对应关系的下行频率资源、或通信装置无需同时应用对应于该SUL CC的下行频域资源。以5G移动通信系统中LTE与NR共存场景为例，SUL CC可以用于以下任一情况：用于NR的上行传输且不用于NR的下行传输、NR中不存在与该SUL CC具有预定义配对关系的下行频率资源、或者与该载波具有预定义配对关系的下行频率资源用于LTE而不用于NR。
在NR的CA场景中，载波类型包括主成员载波(primary component carrier,PCC)和辅成员载波(secondary component carrier,SCC)。
其中，PCC是主小区(primary cell，Pcell)对应的成员载波(component carrier,CC)。Pcell是通信装置初始连接建立的小区、或进行无线资源控制(radio resource control，RRC)连接重建的小区，或是在切换(handover)过程中指定的主小区，负责网络设备与通信装置之间的RRC通信。具体的，Pcell对应的CC包括上行PCC(uplink PCC，UL PCC)和下行PCC(downlink PCC，DL PCC)。
SCC是辅小区(secondary cell，Scell)对应的CC。Scell是RRC重配置时添加的，与网络设备间无RRC通信。在NR中，Scell对应的CC包括但不限于以下几种可能：
1)一对DL SCC和UL SCC；
2)DL SCC；
3)SUL CC；
4)SUL CC和DL SCC；
5)SUL CC，DL SCC和UL SCC。
须知，以上5种可能仅作为举例，不作为对本申请的限定。
在NR的CA场景中，NR支持跨载波调度，跨载波反馈、载波的激活与去激活。下面分别对跨载波调度，跨载波反馈、载波的激活与去激活进行介绍。
(1)NR支持跨载波调度是指当网络设备基于下行载波调度上行载波时，通信装置可以在该下行载波上监测到上行载波的调度信息，该调度信息指示该上行载波对应的时频资源，然后通信装置可以根据该上行载波对应的时频资源在该上行载波上与网络设备进行通信。例如，通信装置可以在该上行载波上向网络设备发送测量报告、用户数据等。
又例如，通信装置通过监测CC1(下行载波)上的物理下行控制信道(physical downlink control channel，PDCCH)可获得CC2(上行载波)被调度信息。通信装置可以在CC2上与网络设备进行通信。
(2)NR支持跨载波反馈是指通信装置在一个PUCCH组内的不同下行载波上接收数据后，在该PUCCH组内的同一上行载波上反馈肯定应答(acknowledge，ACK)或否定应答(negative acknowledge，NACK)。该上行载波具有物理上行控制信道(physical uplink control channel，PUCCH)。
需要说明的是，上行载波具有PUCCH是指该PUCCH对应的时频资源为该上行载波对应的时频资源的一部分。
具体的，若PUCCH组内包括UL PCC，该PUCCH组称为主PUCCH组(Primary PUCCH group)，则UL PCC具有PUCCH，而不含ULPCC的PUCCH组称为辅PUCCH组(Secondary PUCCH group)。
(3)NR支持载波的激活与去激活。
由于受限于终端发射功率，上下行覆盖通常并不平衡，上行覆盖要弱于下行覆盖，且随着高频段的引入，上下行覆盖不平衡的现象更加明显。此外，从业务的角度来看，下行业务需求往往高于上行业务需求，因此上下行业务需求也存在不平衡。NR支持补充上行载波(supplementary UL CC，SUL CC)，SUL CC的提出是希望通过上下行解耦来适应上下行覆盖或上下行业务的不平衡。上下行解耦是指上行CC和下行CC可以独立配置。因此，上行载波不必与调度该上行载波的下行载波同时被激活或去激活，在NR中，当调度SUL CC的下行载波处于去激活状态时，该SUL CC可以处于激活状态。由于NR中支持这种载波类型，因此需要考虑激活与去激活这种类型的载波。
应理解的是，本申请实施例涉及的通信装置可以为终端设备或芯片。例如，该芯片可以位于终端设备中，例如为终端设备中的一个处理芯片。又如，终端设备可以是NR系统或者未来演进的PLMN中的用户设备(user equipment，UE)、接入终端、终端单元、终端站、移动站、移动台、远方站、远程终端、移动设备、无线通信设备、终端代理或终端装置等。接入终端可以是蜂窝电话、无绳电话、会话启动协议(session initiation protocol，SIP)电话、无线本地环路(wireless local loop，WLL)站、个人数字处理(personal digital assistant，PDA)、具有无线通信功能的手持设备、计算设备或连接到无线调制解调器的其它处理设备、车载设备或可穿戴设备等，本申请实施例对此不作具体限定。
本申请实施例涉及的网络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、未来移动通信系统中的基站或WiFi系统中的接入节点等，本申请的实施例对网络设备所采用的具体技术和具体设备形态不做限定。
下面结合附图对本申请的实施例进行说明。
参阅图1所示，本申请提供一种载波状态指示方法，该方法包括：
步骤100：网络设备基于第一下行载波调度第一上行载波。
网络设备通过第一下行载波向通信装置发送第一上行载波的调度信息，该调度信息指示第一上行载波对应的时频资源。此时，第一下行载波和第一上行载波均处于激活状态。
步骤110：通信装置基于第一下行载波在第一上行载波上与网络设备进行通信。
通信装置基于在第一下行载波上接收到的第一上行载波的调度信息，通过第一上行载波向网络设备发送上行信息，上行信息可以为上行数据或上行控制信息。
需要说明的是，上述步骤100和步骤110为可选的步骤，网络设备可以根据实际情况确定是否基于第一下行载波调度第一上行载波。
步骤120：网络设备向通信装置发送载波状态指示信息，载波状态指示信息指示N个为通信装置提供服务的小区对应的M个载波的载波状态，载波状态包括激活状态和去激活状态，N和M均为正整数。
应理解的是，本申请中N个为通信装置提供服务的小区的类型可以是指Scell。
在本申请中，载波状态指示信息可以指示第一下行载波处于去激活状态，第一上行载波处于激活状态，第一下行载波和第一上行载波均为M个载波中的载波。例如，Scell对应的CC包括SUL CC和DL SCC，其中，在DL SCC和SUL CC均处于激活状态时，通信装置可以基于DL SCC在SUL CC上与网络设备进行通信。而载波状态指示信息可以指示SUL CC处于激活状态，而DL SCC处于去激活状态，即只去激活DL SCC，不去激活SUL CC。因此，上述载波状态指示方法能够支持上下行解耦，使上行载波的载波状态不依赖于下行载波的载波状态。
需要说明的是，载波状态指示信息可以采用比特位图(bitmap)的方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态。载波状态指示信息可以通过下行控制信息(Downlink Control Information，DCI)或MAC-CE由网络设备发送给通信装置。
载波状态指示信息可以采用但不限于以下4种方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态：
方式1：载波状态指示信息指示N个为终端提供服务的小区中每个小区对应的上行载波的载波状态和每个小区对应的下行载波的载波状态。
在方式1中，每个小区对应的上行载波状态可被单独配置为激活状态或去激活状态，每个小区对应的下行载波状态可被单独配置为激活状态或去激活状态。当载波状态指示信息采用bitmap的方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态时，具体包括以下两种可能：
1)每个小区对应2个比特，这2个比特分别对应上行载波的载波状态和下行载波的载波状态，此时每个小区对应的各个上行载波的载波状态统一指示，每个小区对应的各个下行载波的载波状态统一指示。
2)每个小区对应的每个上行载波对应1个比特，每个小区对应的每个下行载波对应1个比特。
此外，可以对不包括SUL CC的小区对应CC的载波状态作进一步限定，如不能指示一个不包括SUL CC的小区对应的CC中包括的ULCC处于激活状态，而DL CC处于去激活状态。
因此，采用上述方式1可以实现对各个载波的载波状态进行灵活独立的配置。但是，结合上述Scell对应CC可知，有些Scell可能只对应一个SUL CC或一个DL SCC，如果每个小区对应两个比特，因此，方式1可能会造成资源浪费。或者，可能有至少两个Scell对应的CC中包括同一个DL SCC，因此，该DL SCC的载波状态可能会被重复指示，也会造成资源浪费。
方式2：载波状态指示信息指示M个载波中每个载波的载波状态。
在方式2中，每个载波的载波状态可被单独配置为激活状态或去激活状态。因此，当载波状态指示信息采用bitmap的方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态时，每个载波对应1个比特，例如，1指示载波状态为激活状态，0指示载波状态为去激活状态。
方式2可以支持DL SCC处于去激活状态，SUL CC处于激活状态，也支持DL SCC处于激活状态，与DL SCC配对的UL SCC处于去激活状态。
因此，方式2可以保证每个载波的载波状态得到准确指示，且相较于方式1能够避免资源浪费，且节省了信令开销。
方式3：N个为通信装置提供服务的小区分为三种类型，分别为1)包括预设类型的上行载波和至少一个除预设类型的上行载波外的载波的小区、2)仅预设类型的上行载波的小区、3)不包括预设类型的上行载波的小区。其中，
若N个为通信装置提供服务的小区中的第一小区对应的载波包括预设类型的上行载波和至少一个除预设类型的上行载波外的载波，即第一小区的类型为1)，载波状态指示信息指示第一小区对应的各个载波的载波状态，可以采用但不限于以下方式：
方式A：载波状态指示信息指示第一小区对应的预设类型的上行载波的载波状态，以及第一小区对应的至少一个除预设类型的上行载波外的载波的载波状态。此时，第一小区对应的至少一个除预设类型的上行载波外的载波的载波状态可以统一指示，或者至少一个除预设类型的上行载波外的载波中的每个载波的载波状态可以分别指示。
方式B：载波状态指示信息指示第一小区对应上行载波的载波状态，以及第一小区对应的下行载波的载波状态。
若N个为通信装置提供服务的小区中的第二小区对应的载波包括仅预设类型的上行载波，即第二小区的类型为2)，载波状态指示信息指示第二小区对应的预设类型的上行载波的载波状态。
若N个为通信装置提供服务的小区中的第三小区对应的载波包括不包括预设类型的上行载波，即第三小区的类型为3)，载波状态指示信息指第三小区对应的所有载波的载波状态，其中，第三小区对应的所有载波的载波状态统一指示。
这里的预设类型的上行载波可以为SUL CC，下面以SUL CC为例进行说明。
在方式3中，当载波状态指示信息采用bitmap的方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态时，第一小区采用2个比特指示，1个比特指示第一小区对应的SUL CC的载波状态，另一个比特指示第一小区对应的至少一个除SUL CC外的载波的载波状态。
例如，采用方式A进行指示，当第一小区的CC可以为上述Scell对应CC中的4)时，1个比特指示SUL CC的载波状态，1个比特指示DL SCC的载波状态；当第一小区的CC可以为上述Scell对应CC中的5)时，1个比特指示SUL CC的载波状态，1个比特指示 DL SCC的载波状态和UL SCC的载波状态，例如，1表示DL SCC的载波状态和UL SCC的载波状态均为激活状态，0表示DL SCC的载波状态和UL SCC的载波状态均为去激活状态。
又例如，采用方式B进行指示，当第一小区的CC可以为上述Scell对应CC中的4)时，1个比特指示SUL CC的载波状态，1个比特指示DL SCC的载波状态；当第一小区的CC可以为上述Scell对应CC中的5)时，1个比特指示DL CC的载波状态，1个比特指示SUL CC的载波状态和UL SCC的载波状态，例如，1表示UL SCC的载波状态为去激活状态，SUL SCC的载波状态为激活状态，0表示SUL SCC的载波状态为去激活状态，UL SCC的载波状态为激活状态。
第二小区采用1个比特指示，1个比特指示第二小区对应的SUL CC的载波状态，例如，第二小区的CC可以为上述Scell对应CC中的3)。第三小区采用1个比特指示，1个比特指示第三小区对应的所有载波的载波状态，例如，第三小区的CC可以为上述Scell对应CC中的1)或2)。
例如，网络设备将为通信装置服务的4个cell分别对应的CC事先通知给通信装置。其中，cell 1对应的CC包括：DL CC1和UL CC1，当DL CC1和UL CC1均处于激活状态时，DL CC1用于调度UL CC1。cell 2对应的CC包括：SUL CC1；cell 3对应的CC包括：DL CC2；cell 4对应的CC包括：DL CC3和UL CC2，当DL CC3和UL CC2均处于激活状态时，DL CC3用于调度UL CC2。采用上述方式3进行指示，预设类型的上行载波为SUL CC，则上述4个cell中，cell3对应的CC仅包括SUL CC，与方式3中第二小区的类型相同，可以采用一个bit指示，如图2所示。
因此，方式3可以有效节省信令开销。
方式4：载波状态指示信息指示M个载波中每个下行载波的载波状态和每个预设类型的上行载波的载波状态。
预设类型的上行载波可以为SUL CC。
在方式4中，当载波状态指示信息采用bitmap的方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态时，M个载波中的每个下行载波对应1个比特，每个预设类型的上行载波对应1个比特，此时，与下行载波配对的除预设类型的上行载波外的上行载波不指示，其载波状态与配对的下行载波的载波状态一致。
下面结合不同的实现方式具体说明以上4种方式：
网络设备将为通信装置服务的4个cell分别对应的CC事先通知给通信装置。如图3所示，其中，cell 1对应的CC包括：DL CC1和UL CC1，当DL CC1和UL CC1均处于激活状态时，DL CC1用于调度UL CC1。cell 2对应的CC包括：DL CC1和SUL CC1，当DL CC1和SUL CC1均处于激活状态时，DL CC1用于调度SUL CC1。cell 3对应的CC包括：DL CC2。cell 4对应的CC包括：DL CC3和UL CC2，当DL CC3和UL CC2均处于激活状态时，DL CC3用于调度UL CC2。
网络设备通过bitmap的方式生成载波状态指示信息，其中，1表示载波状态为激活状态，0表示载波状态为去激活状态。
实现方式1：
如图4所示，采用上述方式1进行指示，载波指示信息需要占用8个bit，每个cell 对应2个bit，这2个bit分别对应上行载波的载波状态和下行载波的载波状态。
其中，DL CC1的载波状态被指示了两次，cell3对应的CC只包括DL CC2，但是还是占用了2个bit。
实现方式2：
如图5所示，采用上述方式2进行指示，由于这4个cell共对应6个CC，因此，载波指示信息需要占用6个bit，每个bit对应一个载波的载波状态。
实现方式3：
如图6所示，采用上述方式3进行指示，预设类型的上行载波为SUL CC，则上述4个cell中，cell1对应的CC不包括SUL CC，可以采用一个bit指示，当该bit指示为1时，cell1对应的CC(即DL CC1和UL CC1)均处于激活状态，当该bit指示为0时，cell1对应的CC(即DL CC1和UL CC1)均处于去激活状态。cell2对应的CC包括SUL CC1和DL CC1，因此需要两个bit分别指示cell2对应的DL CC1的载波状态和SUL CC1的载波状态。同理，cell3对应的CC和cell4对应的CC均不包括SUL CC，所以cell3对应的CC采用1bit指示，cell4对应的CC采用1bit指示。
由上可知，载波状态指示信息共需占用5个bit。因此，采用上述方式3进行指示能够节省信令开销。
实现方式4：
如图7所示，采用上述方式4进行指示，上述4个cell共对应6个CC，其中，包括3个DL CC，1个SUL CC和2个UL CC。因此，载波指示信息需要占用4个bit，分别对应3个DL CC和1个SUL CC。其中。UL CC1的载波状态与DL CC1的载波状态相同，UL CC2的载波状态与DL CC3的载波状态相同，没有占用bit进行单独指示。因此，采用上述方式4进行指示也能够节省信令开销。
下面结合不同的实现方式具体说明方式1和方法3。
网络设备将为通信装置服务的3个cell分别对应的CC事先通知给通信装置。其中，cell 1对应的CC包括：DL CC1、UL CC1和SUL CC1；当DL CC1和UL CC1均处于激活状态且SUL CC1处于去激活状态时，DL CC1用于调度UL CC1。当DL CC1和SUL CC1均处于激活状态且UL CC1处于去激活状态时，DL CC1用于调度SUL CC1。当DL CC1、SUL CC1、UL CC1处于去激活状态时，DL CC1用于调度SUL CC1和UL CC1。
cell 2对应的CC包括：DL CC2；cell 3对应的CC包括：DL CC3和UL CC2。当DL CC3和UL CC2均处于激活状态时，DL CC3用于调度UL CC2。
实现方式1：
如图8(a)所示，采用上述方式1进行指示，载波指示信息需要占用6个bit，每个cell对应2个bit，这2个bit分别对应上行载波的载波状态和下行载波的载波状态。其中，1个bit指示UL CC1的载波状态和SUL CC1的载波状态。
实现方式2：
如图8(a)所示，采用上述方式1进行指示，载波指示信息需要占用7个bit，每个cell对应的bit数由该cell对应的CC的数目确定，至少占用2个bit。其中，cell1对应的CC包括3个CC，则占用3个bit，cell2对应的CC只包括DL CC2，但是还是占用了2个bit。cell 3对应的CC包括2个CC，占用2个bit。
实现方式3：
如9(a)所示，采用上述方式3中的方式B进行指示，载波指示信息需要占用4个bit，其中，cell2和cell3各对应1个bit。cell对应的CC中DL CC1对应1个bit，SUL CC1和UL CC1对应1个bit，其中，0表示SUL CC1处于去激活状态，UL CC1处于激活状态，1表示SUL CC1处于激活状态，UL CC1处于去激活状态。进一步地，可以限定b0指示的内容与b1指示的内容具有关联关系，例如，限定b0＝1且b1＝0，即DL CC1处于激活状态，SUL CC1处于去激活状态，UL CC1处于激活状态。
实现方式4：
如9(b)所示，采用上述方式3中的方式A进行指示，载波指示信息需要占用4个bit，其中，cell2和cell3各对应1个bit。cell对应的CC中SUL CC1对应1个bit，DL CC1和UL CC1对应1个bit，其中，0表示DL CC1处于去激活状态，UL CC1处于去激活状态，1表示DL CC1处于激活状态，UL CC1处于激活状态。进一步地，可以限定b0指示的内容与b1指示的内容具有关联关系，例如，限定b0＝0且b1＝1，即SUL CC1处于去激活状态，DL CC1处于激活状态，UL CC1处于激活状态。
实现方式5：
如9(b)所示，采用上述方式3中的方式A进行指示，载波指示信息需要占用5个bit，其中，cell2和cell3各对应1个bit。cell对应的CC中SUL CC1对应1个bit，DL CC1对应1个bit，UL CC1对应1个bit，即包括SUL CC的cell中各个CC分别指示。
通过上述方式1和方式3的比较可以得出，方式3能够有效地节省信令开销。
进一步地，当第一下行载波处于去激活状态，而第一上行载波处于激活状态时，还需考虑如何为第一上行载波重新配置调度该第一上行载波的下行载波。例如，假设第一上行载波为SUL CC，当调度SUL CC的下行载波处于去激活状态，而该SUL CC处于激活状态时，还需考虑如何为该SUL CC重新配置调度该SUL CC的下行载波。
因此，通信装置需要确定调度第一上行载波的第二下行载波。通信装置确定第二下行载波可以采用但不限于以下两种方式：
第一种方式：通信装置根据载波状态指示信息指示的M个载波中处于激活状态的下行载波和第一指示信息确定第二下行载波。其中，第一指示信息是预定义或预配置的，第一指示信息用于指示调度第一上行载波的下行载波的优先级。
第一指示信息是预定义的，是指第一指示信息由通信协议规定，无需网络设备将其通知给通信装置。第一指示信息是预配置的，是指第一指示信息需要由网络设备事先通知给通信装置。
例如，第一指示信息指示调度第一上行载波的下行载波的优先级顺序为下行载波1、下行载波3、下行载波4。通信装置根据载波状态指示信息确定处于激活状态的下行载波，若下行载波1处于激活状态，则通信装置确定下行载波1作为第二下行载波，若下行载波1处于去激活状态，下行载波3和下行载波4均处于激活状态，则根据优先级顺序，通信装置确定下行载波3作为第二下行载波。
第二种方式：第二下行载波是预定义的，或者第二下行载波由网络设备直接通知给通信装置，则通信装置可直接确定第二下行载波。
在一种可能的设计中，第二下行载波为DL PCC。
在一种可能的设计中，载波指示信息还包括调度第一上行载波的下行载波的载波标识， 即第二下行载波的载波标识。例如，如图10所示，载波指示信息中包括调度SUL CC的下行载波的载波标识(DL CC ID)。
其中，载波标识占用的比特长度可以固定，例如占用4bit指示第二下行载波的载波标识。
或者，载波标识占用的比特长度可根据当前处于激活状态的DL CC数量确定，例如，当前处于激活状态的DL CC为4个时，可以使用2bit指示第二下行载波的载波标识。
在一种可能的设计中，当载波状态指示信息通过MAC-CE发送给通信装置时，载波指示信息还包括调度第一上行载波的下行载波的载波标识，例如，载波状态指示信息还包括为SUL CC重新配置的调度SUL CC的DL CC的载波标识。当载波状态指示信息通过DCI发送给通信装置时，载波指示信息不包括调度第一上行载波的下行载波的载波标识，例如，载波状态指示信息不包括为SULCC重新配置的调度SUL CC的DL CC的载波标识，此时调度SUL CC的DL CC可以采用上述其他方式确定。
在通信装置确定第二下行载波后，通信装置可基于第二下行载波在第一上行载波上与网络设备进行通信。
参阅图11所示，本申请提供一种载波状态指示方法，该方法包括：
步骤1100：网络设备向通信装置发送载波状态指示信息，载波状态指示信息指示N个为通信装置提供服务的小区对应的M个载波的载波状态，载波状态包括激活状态和去激活状态，N和M均为正整数。
其中，载波状态指示信息指示第一上行载波处于激活状态，在网络设备向通信装置发送载波状态指示信息之后，第一上行载波从去激活状态切换到激活状态。
例如，Scell对应的CC包括SUL CC和DL SCC，在通信装置接收到载波状态指示信息之前，SUL CC处于去激活状态，载波状态指示信息可以指示SUL CC处于激活状态，而DL SCC的载波状态可以为激活状态或去激活状态。因此，上述载波状态指示方法能够支持上下行解耦，使上行载波的载波状态不依赖于下行载波的载波状态。
载波状态指示信息可以采用但不限于如图1所示实施例提供的4种方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态，此处不再赘述。
步骤1110：网络设备基于第一下行载波调度第一上行载波。
网络设备通过第一下行载波向通信装置发送第一上行载波的调度信息，该调度信息指示第一上行载波对应的时频资源。
步骤1120：通信装置基于第一下行载波在第一上行载波上与网络设备进行通信。
通信装置基于在第一下行载波上接收到的第一上行载波的调度信息，通过第一上行载波向网络设备发送上行信息，上行信息可以为上行数据或上行控制信息。
其中，步骤1110和步骤1120为可选的步骤。通信装置若要执行步骤1110和步骤1120，需要确定调度第一上行载波的第一下行载波。应理解的是，通信装置确定第一下行载波可以采用上述图1所示实施例中通信装置确定第二下行载波的方法，重复之处不再赘述。
在一种可能的设计中，第一指示信息指示在第一上行载波最近一次处于激活状态时调度第一上行载波的下行载波的优先级高于DL PCC。
例如，第一指示信息指示在SUL CC最近一次处于激活状态时调度SUL CC的下行载波的优先级高于DL PCC。假设在SUL CC最近一次处于激活状态时调度SUL CC的下行 载波为DL CC1，若载波状态指示信息指示SUL CC处于激活状态，而DL CC1也处于激活状态，则通信装置确定第一下行载波为DL CC1，若载波状态指示信息指示DL CC1处于去激活状态，则通信装置确定第一下行载波为DL PCC。
由上可知，结合图1和图11所示的实施例可知，相较于现有技术中，载波的激活与去激活是以Scell为单位进行的，例如，Scell对应的CC被激活或去激活，即激活或去激活一对DL SCC和UL SCC，或者激活或去激活一个DL SCC。采用本申请实施例提供方法，能够支持上下行解耦，使上行载波的载波状态不依赖于下行载波的载波状态，上下行载波的激活与去激活可以实现独立灵活的配置。
除了SUL CC外，还有一种激活与去激活的场景是NR中新出现的。在LTE中，在主PUCCH组中，UL PCC具有PUCCH，而UL PCC不可被去激活，因此主PUCCH组中具有PUCCH的UL CC不可被去激活。而在NR中，在主PUCCH组中，具有PUCCH的UL CC可以是除UL PCC以外的其他UL CC，因此，存在具有PUCCH的UL CC被去激活的可能，因此，还需考虑如何重新配置具有PUCCH的UL CC。
参阅图12所示，本申请还提供一种载波状态指示方法，该方法包括：
步骤1200：网络设备向通信装置发送载波状态指示信息，载波状态指示信息指示N个为通信装置提供服务的小区对应的M个载波的载波状态，载波状态包括激活状态和去激活状态，N和M均为正整数。
其中，载波状态指示信息指示第二上行载波处于去激活状态，第二上行载波具有PUCCH，第二上行载波为M个载波中的载波，且第二上行载波为主PUCCH组中的载波。
因此，主PUCCH组中具有PUCCH的UL CC存在被去激活的可能。
载波状态指示信息可以采用但不限于如图1所示实施例提供的4种方式指示N个为通信装置提供服务的小区对应的M个载波的载波状态，此处不再赘述。
进一步地，载波状态指示信息指示M个载波中的第三上行载波处于激活状态，第三上行载波具有PUCCH，第三上行载波为主PUCCH组中的载波。
与上述图1所述实施例中通信装置确定第二下行载波类似，通信装置确定第三上行载波可以采用但不限于以下两种方式：
第一种方式：通信装置根据载波状态指示信息指示的M个载波中处于激活状态的上行载波和第二指示信息确定第三上行载波，第二指示信息是预定义或预配置的，第二指示信息用于指示具有PUCCH的上行载波的优先级。
例如，第一指示信息指示具有PUCCH的上行载波的优先级顺序为上行载波1、上行载波3、上行载波4。通信装置根据载波状态指示信息确定处于激活状态的上行载波，若上行载波1处于激活状态，则通信装置确定上行载波1作为第三上行载波，若上行载波1处于去激活状态，上行载波3和上行载波4均处于激活状态，则根据优先级顺序，通信装置确定上行载波3作为第三上行载波。
第二种方式：第三上行载波是预定义的，或者第三上行载波由网络设备直接通知给通知装置，则通信装置可直接确定第二下行载波。
在一种可能的设计中，第三上行载波为UL PCC。
在一种可能的设计中，载波指示信息还包括具有PUCCH的上行载波的载波标识，即第三上行载波的载波标识。
其中，载波标识占用的比特长度可以固定，例如占用4bit指示第三上行载波的载波标识。
或者，载波标识占用的比特长度可根据当前处于激活状态的UL CC数量确定，例如，当前处于激活状态的UL CC为4个时，可以使用2bit指示第三上行载波的载波标识。
在一种可能的设计中，当载波状态指示信息通过MAC-CE发送给通信装置时，载波状态指示信息还包括重新配置的具有PUCCH的上行载波的载波标识。当载波状态指示信息通过DCI发送给通信装置时，载波状态指示信息不包括重新配置的具有PUCCH的上行载波的载波标识，具有PUCCH的上行载波可以采用上述其他方式确定。
步骤1210：网络设备基于主PUCCH组中的下行载波向通信装置发送下行数据。
其中，该下行载波的载波状态为激活状态，可以通过上述载波状态指示信息获知。
步骤1220：通信装置在该下行载波上接收下行数据后，在第三上行载波上向网络设备反馈ACK或NACK。
应理解的是，步骤1210和步骤1220为可选的步骤，网络设备可以根据实际业务情况确定是否基于主PUCCH组中的下行载波向通信装置发送下行数据。
