PUCCH传输方法、终端设备和网络设备
相关申请的交叉引用
本申请主张在2019年08月22日在中国提交的中国专利申请号201910780288.1的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种PUCCH传输方法、终端设备和网络设备。
背景技术
目前，在长期演进(Long Term Evolution，LTE)标准化过程中，为了满足不断增长的业务需求，增大系统带宽，引入了载波聚合(Carrier Aggregation，CA)技术，使得系统可以至多聚合5个具有相同讯框架构(Frame Structure)的成员载波(Component Carrier，CC)，即最大支持100MHz带宽。进一步随着通讯业务需求的不断增长，系统需要更大的频宽、聚合更多的成员载波时，引入了增强载波聚合(enhanced Carrier Aggregation，eCA)技术，扩展了可支持多到32个CC间的聚合。
另外，为了解决服务小区边缘用户的覆盖问题，还引入了双连接(Dual-Connectivity，DC)技术，即终端设备(User Equipment，UE)同时跟两个网络设备保持着连接。如图1所示，UE处于服务小区边缘，如果光靠网络设备A，UE的信号强度可能不够，则可以在服务小区边缘部署网络设备B，并把网络设备A和网络设备B配置成DC，用于增强覆盖，如此UE可以同时跟网络设备A和网络设备B保持连接。其中，DC技术与CA技术的区别在于：DC下的两个网络设备是独立调度的，即UE 必须得有两个不同媒体接入控制(Medium Access Control，MAC)实体，一个对应网络设备A，另一个对应网络设备B；而CA下所有的CC都对应同一个MAC实体。
进一步随着技术的不断进步，新功能的引入需要考虑支持多于1个物理上行控制信道(Physical Uplink Control Channel，PUCCH)的同时传输。在DC技术中，提出了支持2个PUCCH同时传输以向辅网络设备反馈其服务小区组的PUCCH。而对于eCA，如果将32个载波的上行控制信息都放在一个PUCCH上传输，将会占用很大的PUCCH资源，也不利于灵活调度，因此为了负载均衡，在eCA技术中也引入了两个PUCCH同时传输。
在新空口(New Radio，NR)移动通信系统中，非授权频段可以作为授权频段的补充帮助运营商对服务进行扩容。为了与NR部署保持一致并尽可能的最大化基于NR的非授权接入，非授权频段可以工作在5GHz、37GHz和60GHz频段。非授权频段的大带宽能够减小网络设备与UE的实施复杂度。由于非授权频段由多种无线接入技术共用，比如无线宽带(Wireless-Fidelity，Wi-Fi)、雷达、LTE授权辅助接入(Licensed-Assisted Access，LAA)等，因此，非授权频段在使用时必须符合某些规则以保证所有设备可以公平的使用该资源，比如发前听(Listen Before Talk，LBT)、最大信道占用时间(Maximum Channel Occupancy Time，MCOT)等规则。
但是，当特殊服务小区(Special Cell，SpCell)或PUCCH-辅服务小区(Secondary Cell，SCell)配置在非授权频段时，其中，SpCell包括主小区组的主服务小区(Primary Cell，PCell)和辅小区组的主服务小区(Primary Secondary Cell，PSCell)，UE在传输物理上行控制信道(Physical Uplink Control Channel，PUCCH)之前需要进行先听后发(Listen Before Talk，LBT)以检测信道状态，当信道检测为忙时，UE将 不能发送PUCCH，将会大大影响SpCell或PUCCH-SCell对应的PUCCH组的上行控制信息(Uplink Control Information，UCI)的发送，会降低通信系统的性能。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例进行清楚、完整地描述，显然，所描述的实施例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作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。
本公开可以应用于各种通信系统，例如：全球移动通讯系统(Global System of Mobile communication，GSM)，码分多址(Code Division Multiple Access，CDMA)系统，宽带码分多址(Wideband Code Division Multiple Access，WCDMA)，通用分组无线业务(General Packet Radio Service，GPRS)，长期演进(Long Term Evolution，LTE)/增强长期演进(Long Term EvolutionAdvanced，LTE-A)，NR(New Radio)等。
用户端(User Equipment,UE)，也可称之为终端设备(Mobile Terminal)、移动用户设备等，可以经无线接入网(Radio Access Network，RAN)与一个或多个核心网进行通信，用户设备可以是终端设备，如移动电话(或称为“蜂窝”电话)和具有终端设备的计算机，例如，可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置，它们与无线接入网交换语言和/或数据。
基站，可以是GSM或CDMA中的基站(Base Transceiver Station，BTS)，也可以是WCDMA中的基站(NodeB)，还可以是LTE中的演进型基站(evolutional Node B，eNB或e-NodeB)及5G基站(gNB)，本公开并不限定，但为描述方便，下述实施例以gNB为例进行说明。
对于背景技术部分陈述的双连接DC和增强载波聚合eCA场景下的支持2个PUCCH同时传输，具体有如下规定：
在一个PUCCH组(PUCCH group)内的服务小区为对应同一个PUCCH资源的服务小区，具体可以包括主PUCCH组和辅PUCCH组，或者如图2所示的主小区组(Master Cell Group，MCG)和辅小区组(Secondary Cell Group，SCG)。
其中，在增强载波聚合eCA场景下，主PUCCH组的PUCCH资源配置在PCell上，以传输主PUCCH组内各服务小区的上行控制信令；辅PUCCH组的PUCCH资源配置在SCell上(即PUCCH SCell)，以传输辅PUCCH组内各服务小区的上行控制信令。其中，主PUCCH组或者辅PUCCH组中包含哪些下行服务小区，哪些上行服务小区都是网络侧通过高层信令配置的。
在DC场景下，MCG的PUCCH资源配置在PCell上，以传输MCG各服务小区的上行控制信令，SCG的PUCCH资源配置在PSCell上，以传输SCG各服务小区的上行控制信令。其中，MCG或者SCG中包含哪些下行服务小区，哪些上行服务小区都是网络侧通过高层信令配置的。
考虑到UE可能同时配置双连接功能，多个PUCCH传输的配置应优先用于双连接，当双连接没有配置时，额外的PUCCH可配置给eCA的辅小区。当配置PUCCH辅小区时，通过无线资源控制(Radio Resource Control，RRC)信令配置每个服务小区到主PUCCH组或辅PUCCH组的映射关系，即对于每个服务小区是使用PCell还是PUCCH SCell传输肯定确认(Acknowledgement，ACK)/否定确认(Negative Acknowledgement，NACK)消息和信道状态信息(Channel State Information，CSI)报告。
网络设备可以通过激活和去激活配置PUCCH SCell，当PUCCH SCell去激活时，辅PUCCH组内的辅小区也不能被激活。
在本公开实施例中，提出了一种能够解决在空闲信道检测结果为忙时，UE不能发送PUCCH，影响PUCCH组的上行控制信息的发送，降低通信系统性能的问题。以下结合附图，详细说明本公开各实施例。
图3示出本公开第一方面提供的PUCCH传输方法的实施例的流程示意图，该方法可以由电子设备执行，例如终端设备。换言之，方法可 以由安装在终端设备的软件或硬件来执行。如图3所示，该方法可以包括以下步骤：
步骤101：在分别配置有PUCCH资源的多个上行服务小区中确定目标上行服务小区，目标上行服务小区为多个上行服务小区中的一个；
步骤103：在目标上行服务小区上发送PUCCH。
本公开实施例中，通过网络设备为多个上行服务小区中的每个上行服务小区分别配置PUCCH资源，以能够根据实际的具体需求在该多个分别配置有PUCCH资源的上行服务小区确定一个目标上行服务小区，如此，终端设备可以在该目标上行服务小区上及时有效的发送PUCCH，从而提高上行控制信息传输的可靠性，提高通信系统的系统性能。
步骤101可以执行为不同的具体实施例，以实现目标上行服务小区确定方式的多样性。
具体实施例一
在该具体实施例一中，步骤101可以具体执行为如下内容：
接收网络设备发送的切换指示信令；
根据切换指示信令，在多个上行服务小区中确定目标上行服务小区。
可以理解，终端设备可以根据网络设备的具体切换指示在分别配置有PUCCH资源的多个上行服务小区中确定能够实现及时有效的PUCCH发送的目标服务小区，也就是说，终端设备可以根据来自网络设备的切换指示信令在配置有PUCCH资源的不同的上行服务小区间进行动态切换确定目标服务小区。
在一个示例中，步骤103，可以具体执行为如下内容：
从接收到切换指示信令的结束时刻起的预设时间后，在目标上行服务小区上发送PUCCH。
可以理解，考虑到终端设备切换发送PUCCH的上行服务小区需要时间，为了确保有充足的时间完成PUCCH所在上行服务小区的切换，同时在网络侧和终端侧对PUCCH传输所在的服务小区有一致的理解，需要规范切换指示信令的生效时间，即终端设备可以在接收到切换指示信令的结束时刻起的预设时间，如预设数量的符号或时隙后，开始在目标上行服务小区上进行PUCCH的发送。其中，预设时间可以是由一定数量的时隙或正交频分复用(Orthogonal Frequency Division Multiplex，OFDM)符号定义，该数量的值可以是网络设备通过RRC信令为终端设备配置的值，或者可以为协议规定的值，或者也可以为跟终端设备的处理能力有关的值。
在一个示例中，接收网络设备发送的切换指示信令的方案，可以具体执行为如下内容：
通过终端设备专用(UE-specific)下行控制信息(Downlink Control Information，DCI)、组公共(group common)DCI和小区专用(cell-specific)DCI中的一个，接收切换指示信令。
在一个示例中，分别配置有PUCCH资源的多个上行服务小区可以被分配在不同的PUCCH组中，如此，可以根据网络设备发送的切换指示信令在不同的PUCCH组之间实现发送PUCCH的上行服务小区(即PUCCH所在的上行服务小区)的动态切换。
在一个示例中，在多个上行服务小区包括第一PUCCH组内的第一上行服务小区和第二PUCCH组内的第二上行服务小区的情况下，根据切换指示信令，在多个上行服务小区中确定目标上行服务小区的方案，可以具体执行为如下内容：
根据切换指示信令，从当前用于发送PUCCH的第一上行服务小区切换至第二上行服务小区，第一上行服务小区的PUCCH资源和第二上行服务小区的PUCCH资源处于激活状态；
将第二上行服务小区确定为目标上行服务小区。
可以理解，例如在当前用于发送PUCCH的第一上行服务小区进行空闲信道状态检测的结果为信道忙时，终端设备无法在第一上行服务小区发送PUCCH，若网络设备一定时间内都无法接收到相应的PUCCH，则可以发送切换指示信令给终端设备，进而终端设备可以根据网络设备发送的切换指示信令从第一上行服务小区切换到第二PUCCH组内PUCCH资源处于激活状态的第二上行服务小区，实现发送PUCCH的上行服务小区的有效切换的同时，通过直接切换到PUCCH资源处于激活状态的上行服务小区，可以提高PUCCH的发送效率。
其中，第一PUCCH组除第一上行服务小区外，还可以包括多个上行服务小区中的一个或多个；第二PUCCH组除第二上行服务小区外，还可以包括多个上行服务小区中的一个或多个。
在一个示例中，在第一PUCCH组包括CA模式下的主PUCCH组时，第二PUCCH组可以包括CA模式下的辅PUCCH组，反之也成立；或者在第一PUCCH组包括DC模式下的主小区组时，第二PUCCH组可以包括DC模式下的辅小区组，反之亦成立。
在一个示例中，第一PUCCH组内和第二PUCCH组内分别有一个上行服务小区上配置了PUCCH资源，或者在每个PUCCH组内在同一时间有一个上行服务小区对应的PUCCH资源处于激活状态或可用状态，也就是说，每个PUCCH组内包括至少一个配置有PUCCH资源的上行服务小区。
在一个示例中，在确定目标上行服务小区后，PUCCH传输方法还可以包括以下内容：
在目标上行服务小区上，发送第一PUCCH组对应的各下行服务小区对应的第一UCI和第二PUCCH组对应的各下行服务小区对应的第二UCI。
可以理解，将不同PUCCH组对应的各下行服务小区对应的上行控制信息(Uplink Control Information，UCI)均在目标上行服务小区上发送，其中，各上行控制信息可以包括混合自动重传请求确认(Hybrid Automatic Repeat Request Acknowledgement，HARQ-ACK)反馈信息或CSI报告。
在一个示例中，在第一UCI包括第一HARQ-ACK反馈信息，第二UCI包括第二HARQ-ACK反馈信息的情况下，在目标上行服务小区上，发送第一PUCCH组对应的各下行服务小区对应的第一UCI和第二PUCCH组对应的各下行服务小区对应的第二UCI的方案，可以具体执行为如下内容之一：
(1)在目标上行服务小区上，采用在第一PUCCH组内构建的第一HARQ-ACK码本方式发送第一HARQ-ACK反馈信息、采用在第二PUCCH组内构建的第二HARQ-ACK码本方式发送第二HARQ-ACK反馈信息。也就是说，按照切换用于发送PUCCH的上行服务小区(即PUCCH所在的上行服务小区)之前所采用的HARQ-ACK码本构建方式，分别在各自的PUCCH组内构建HARQ-ACK码本。
(2)在目标上行服务小区上，采用在由第一PUCCH组和第二PUCCH组构成的PUCCH合并组内构建的第三HARQ-ACK码本方式，发送第一HARQ-ACK反馈信息和第二HARQ-ACK反馈信息。也就是说，可以按照将不同的PUCCH组合并后对应的HARQ-ACK码本构建方式构建HARQ-ACK码本。
举例来说，参照图4，网络设备可以通过RRC信令为UE下行配置32个CC(即32个下行服务小区)，其中，CC 0～CC 15映射到主PUCCH 组(Primary PUCCH Group)，其PUCCH资源配置在PCell上，且PCell位于授权频段，CC 16～CC 31映射到辅PUCCH组(Secondary PUCCH Group)，其PUCCH资源配置在SCell(即PUCCH SCell)上，且PUCCH SCell位于非授权频段。
那么对于下行服务小区CC 16～CC 31，其调度的物理下行共享信道(Physical Downlink Shared Channel，PDSCH)或CSI测量，UE需要在PUCCH SCell上反馈HARQ-ACK或CSI。由于PUCCH SCell位于非授权频段，UE在发送HARQ-ACK PUCCH或CSI PUCCH前都要进行空闲信道检测，只有当检测到信道为空时，UE才能够发送HARQ-ACK PUCCH或CSI PUCCH，反之，如果信道为忙，则不能发送HARQ-ACK PUCCH或CSI PUCCH。如果在比较长的一段时间内，UE一直检测到信道为忙而无法抢占到信道，则辅PUCCH组对应的下行服务小区CC 16～CC 31对应的HARQ-ACK和CSI反馈将一直无法反馈给网络设备，进而会给网络设备的下行调度和信道测量带来不利的影响。
此时，网络设备可以向UE发送切换指示信令，指示UE将辅PUCCH组对应的下行服务小区CC 16～CC 31对应的上行控制信息在主PUCCH组的上行服务小区上发送，即在PCell上发送。由于PCell是位于授权频段，因此，只要有PUCCH资源，UE即可发送上行控制信息，保证了下行服务小区CC 16～CC 31对应的上行控制信息的正常发送，有利于提高系统的有效性和下行吞吐量。
进一步地，考虑到UE切换用于发送PUCCH的上行服务小区需要时间，UE在收到指示切换的物理下行控制信道(Physical Downlink Control Channel，PDCCH)命令(即切换指示信令)后的一定时间后，才会切换到另一个上行服务小区发送PUCCH，其中一定的时间可以是X个OFDM符号/时隙slot，如图5所示，X的值可以是RRC信令配置或协议规定或与 UE的处理能力有关。即UE在收到命令后的X个OFDM符号/时隙slot后，UE收到CC 16～CC 31上调度的PDSCH/释放半持续调度(Semi-Persistent Scheduling，SPS)PDSCH的PDCCH，对应的HARQ-ACK反馈，UE将在PCell上反馈。如果在指示切换的PDCCH之前UE收到的CC 16～CC 31上调度的PDSCH/释放SPS PDSCH的PDCCH，其HARQ-ACK反馈被调度的切换指示信令的PDCCH之后反馈，时间间隔小于X个OFDM符号/slot，则UE可以不发送该HARQ-ACK。
对于UE在收到命令后的X个OFDM符号/slot后，UE收到CC 16～CC 31上调度的PDSCH/释放SPS PDSCH的PDCCH，对应的HARQ-ACK反馈，UE将在PCell上反馈。或者UE收到CC 16～CC 31上调度的PDSCH/释放SPS PDSCH的PDCCH，其对应的HARQ-ACK反馈的时间在切换命令后的X个OFDM符号/slot之后，则其对应的HARQ-ACK反馈，UE将在PCell上反馈。UE在反馈HARQ-ACK时，UE要反馈CC 16～CC 31上调度的PDSCH/释放SPS PDSCH的PDCCH，也要反馈CC 16-31上调度的PDSCH/释放SPS PDSCH的PDCCH，对于UE反馈HARQ-ACK时的HARQ-ACK码本(codebook)的构建，UE可以按照切换前的方式CC 0～CC 15和CC 16～CC 31的HARQ-ACK码本分别构建，即CC 0～CC 15构建一个HARQ-ACK码本，CC 16～CC 31构建一个码本，两个码本构建互不影响。或者UE按照CC 0～CC 31是一个PUCCH组的方式构建一个HARQ-ACK码本。
需要说明的是，“从接收到切换指示信令的结束时刻起的预设时间后，根据切换指示信令，在目标上行服务小区上发送PUCCH”表示从接收到切换指示信令的结束时刻起的预设时间后，终端侧可以在目标上行服务小区上发送PUCCH，并不表示终端设备一定会在接收到切换指示信令 的结束时刻起的预设时间后的时刻发送，终端设备发送PUCCH的具体时间取决于网络侧的调度或配置。
在一个示例中，分别配置有PUCCH资源的多个上行服务小区中的至少两个上行服务小区可以被分配在同一个PUCCH组中，如此，可以根据网络设备发送的切换指示信令在同一PUCCH组内实现发送PUCCH的上行服务小区的动态切换。
在一个示例中，在多个上行服务小区包括目标PUCCH组内第三上行服务小区和第四上行服务小区的情况下，也就是说，目标PUCCH组内包括至少两个配置有PUCCH资源的上行服务小区，根据切换指示信令，在多个上行服务小区中确定目标上行服务小区的方案，可以具体执行为如下内容：
根据切换指示信令，从当前用于发送PUCCH的第三上行服务小区切换至第四上行服务小区；
将第四上行服务小区确定为目标上行服务小区。
其中，目标PUCCH组为预配置的至少一个PUCCH组中的一个，目标PUCCH组内在同一时间仅有一个上行服务小区对应的PUCCH资源处于激活状态。
可以理解，在一个PUCCH组内，网络设备在多个上行服务小区上分别置PUCCH资源，但是同一时间，只有一个上行服务小区的PUCCH资源处于激活/可用状态。在一个示例中，在当前用于发送PUCCH的第三上行服务小区进行空闲信道状态检测的结果为信道忙时，终端设备无法在第三上行服务小区发送PUCCH，若网络侧在一定时间内都无法接收到相应的PUCCH，则可以发送切换指示信令给终端设备，终端设备可以根据该切换指示信令从第三上行服务小区切换到该目标PUCCH组内的第四上行 服务小区，并使第四上行服务小区对应的PUCCH资源进入激活状态/可用状态，实现发送PUCCH的上行服务小区的有效切换。
在一个示例中，目标PUCCH组可以包括CA模式下的主PUCCH组或者辅PUCCH组。
在一个示例中，目标PUCCH组还可以包括DC模式下的主小区组或者辅小区组。
在一个示例中，在确定目标上行服务小区后，该方法还可以包括以下内容：
在目标上行服务小区上发送目标PUCCH组对应的各下行服务小区对应的第三UCI。
可以理解，将该目标PUCCH组对应的各下行服务小区对应的上行控制信息UCI在目标上行服务小区上发送，其中，该第三上行控制信息可以包括混合自动重传请求确认HARQ-ACK反馈信息或CSI报告。
在一个示例中，在第三UCI包括第三HARQ-ACK反馈信息的情况下，在目标上行服务小区上发送目标PUCCH组对应的各下行服务小区对应的第三UCI的方案，可以具体执行为如下内容：
在目标上行服务小区上，采用在目标PUCCH组内构建的第三HARQ-ACK码本方式发送第三HARQ-ACK反馈信息。也就是说，可以按照切换用于发送PUCCH的上行服务小区之前所采用的HARQ-ACK码本构建方式继续构建HARQ-ACK码本。
举例来说，如图6所示，UE配置了DC模式。其中MCG下行配置了一个或多个上行服务小区，MCG的上行控制信息在PCell上反馈，SCG也下行配置了一个或多个上行服务小区，SCG的上行控制信息在PSCell上反馈。其中PCell位于授权频段，PSCell位于非授权频段，另外，SCG的上行聚合了多个上行服务小区，如上行服务小区0,1,2,3,4，且都位于非授权 频段，其中PSCell为上行服务小区0。由于SCG的所有下行服务小区调度的PDSCH/释放SPS PDSCH的PDCCH的HARQ-ACK反馈和CSI反馈都要配置在PSCell的PUCCH上反馈，当PSCell的信道条件比较差(比如，被其他接入点抢占)，UE长时间无法接入信道时，SCG上的HARQ-ACK/CSI反馈将无法传输。此时如果SCG中上行聚合的其他上行服务小区(比如上行服务小区1,2,3,4)的信道条件比较好(相对比较空闲)，网络设备可以指示UE将SCG的用于发送PUCCH的上行服务小区切换到其他上行服务小区上，例如切换到上行服务小区1上。
针对切换方式，由于只是在SCG内部切换，因此对MCG的上行控制反馈没有影响，而SCG的上行控制信息反馈，例如HARQ-ACK码本等与切换前的方式一样，即在SCG内部进行码本构建。
在切换方式中还可以包括，网络设备先通过RRC信令在上行服务小区0和上行服务小区1上都配置了PUCCH资源，但是初始时只有PScell，即服务小区0上的PUCCH资源处于激活状态或可用状态，因此UE在服务小区0上反馈SCG的上行控制信息。当接收到网络设备发送的切换用于发送PUCCH的上行服务小区的指示信令后，UE将用于发送PUCCH的上行服务小区切换到上行服务小区1上，并按照RRC信令配置的资源参数(例如PUCCH资源集，CSI PUCCH资源配置，PUCCH传输功率配置等)传输。
需要说明的是，根据网络设备发送的切换指示信令实现的PUCCH所在上行服务小区的切换的方案，并不仅限于在不同的PUCCH组之间的切换和在同一PUCCH组内的切换的方案。
在一个示例中，网络设备发送的切换指示信令包括目标上行服务小区的小区索引号。如此，终端设备可以根据该目标上行服务小区的小区索引号高效的确定最终用于发送PUCCH的目标上行服务小区。
由上可知，通过本公开实施例的PUCCH传输方法，适用于UE配置了DC或至少有上行CA的情况，当用于发送PUCCH的上行服务小区的信道条件比较差时，可以动态切换用于发送PUCCH的上行服务小区，如此，可以提高上行控制信息传输的可靠性，有利于提高通信系统的系统性能。
具体实施例二
在该具体实施例二中，步骤101可以具体执行为如下内容：
在多个上行服务小区中的每个上行服务小区上分别进行空闲信道状态检测，确定备选上行服务小区，备选上行服务小区包括空闲信道状态检测结果为空的所有上行服务小区；
在备选上行服务小区中确定目标上行服务小区。
可以理解，在网络设备为终端设备的多个上行服务小区分别配置PUCCH资源时，终端设备可以在该多个上行服务小区中的每个上行服务小区分别进行空闲信道状态检测，比如LBT，并根据空闲信道状态检测的结果将信道为空的上行服务小区作为用于确定目标上行服务小区的备选上行服务小区，以能够实现及时有效的PUCCH发送。
举例来说，UE上行传输聚合了多个CC，如图7所示的8个(CC0,CC1,CC2…,CC7)，所有上行服务小区都属于非授权频段，其中上行服务小区PCell在CC0上，网络设备通过RRC信令在多个上行服务小区上配置PUCCH资源，例如PCell和CC1,CC2，且每个上行服务小区上配置的PUCCH资源相同。在UE侧，UE根据网络设备的配置或调度在传输PUCCH之前对信道进行LBT。优选的，UE在PCell、CC1和CC2上均进行LBT，如果PCell检测到信道为空，则UE在PCell上发送PUCCH。反之如果PCell上检测信道为忙，且UE在CC1和CC2上中的至少一个上行服务小区上检测到信道为空，则UE选择在其中信道为空闲状态的上行服 务小区上发送PUCCH。在网络设备侧，网络设备需要在PCell、CC1和CC2上通过盲检测的形式接收PUCCH，其中检测到PUCCH的服务小区则为发送PUCCH的上行服务小区。
在一个示例中，在备选上行服务小区有多个的情况下，在备选上行服务小区中确定目标上行服务小区的方案，可以通过以下之一实现：
将备选上行服务小区中小区索引号最小的一个确定为目标上行服务小区；
将备选上行服务小区中信道条件最好的一个确定为目标上行服务小区；
将在备选上行服务小区中随机选择的一个确定为目标上行服务小区。
在一个示例中，在备选上行服务小区有多个的情况下，PUCCH传输方法还可以包括以下内容：
在备选上行服务小区中的每一个上发送PUCCH。
可以理解，当在多个分别配置有PUCCH资源的上行服务小区中，有多个信道条件良好可用于发送PUCCH时，可以在每一个上行服务小区上都发送PUCCH，实现PUCCH的重复发送，以提高PUCCH发送的可靠性。
图8示出本公开第五方面提供的PUCCH传输方法的实施例的流程示意图，该方法可以由电子设备执行，例如网络设备。换言之，方法可以由安装在网络设备的软件或硬件来执行。如图8所示，该方法可以包括以下步骤：
步骤201：在多个上行服务小区上分别配置PUCCH资源；
步骤203：在目标上行服务小区上接收PUCCH，目标上行服务小区为终端设备在多个上行服务小区中确定的上行服务小区。
本公开实施例中，通过为多个上行服务小区分别配置PUCCH资源，以使终端设备能够根据实际的具体需求在该多个配置有PUCCH资源的上行服务小区中确定一个目标上行服务小区，进而可以接收终端设备在该目标上行服务小区上发送的PUCCH，从而及时有效的接收上行控制信息，达到提高上行控制信息传输的可靠性，提高通信系统的系统性能的目的。
在一个示例中，步骤203可以执行为不同的具体实施例，以保证PUCCH高效、可靠接收的多样性。
具体实施例一
在该具体实施例一中，在步骤203之前，该方法还可以包括以下内容：
向终端设备发送切换指示信令，切换指示信令用于指示终端设备在多个上行服务小区中确定目标上行服务小区。
可以理解，网络设备通过向终端设备发送具体的切换指示，使其能够在分别配置有PUCCH资源的多个上行服务小区中高效准确地确定用于实现及时有效的PUCCH发送的目标服务小区，也就是说，使得终端设备可以根据该切换指示信令在配置有PUCCH资源的不同的上行服务小区间进行动态切换确定目标服务小区。
在一个示例中，步骤203可以具体执行为如下内容：
在向终端设备发送完切换指示信令的结束时刻起的预设时间后，在目标上行服务小区上接收PUCCH。
可以理解，考虑到终端设备切换发送PUCCH的上行服务小区需要时间，为了确保有充足的时间完成PUCCH所在上行服务小区的切换，同时在网络侧和终端侧对PUCCH传输所在的服务小区有一致的理解，需要规范切换指示信令的生效时间，即网络设备可以在发送完切换指示信令的结束时刻起的预设时间，如预设数量的符号或时隙后，开始在目标上行服务 小区上接收PUCCH。其中，预设时间可以是由一定数量的时隙或OFDM符号定义，该数量的值可以是网络设备通过RRC信令为终端设备配置的值，或者可以为协议规定的值，或者也可以为跟终端设备的处理能力有关的值。
在一个示例中，向终端设备发送切换指示信令的方案，可以具体执行为如下内容：
通过终端设备专用下行控制信息DCI、群组共用DCI和服务小区专用DCI中的一个，向终端设备发送切换指示信令。
在一个示例中，分别配置有PUCCH资源的多个上行服务小区可以被分配在不同的PUCCH组中，如此，可以配置切换指示信令用于指示终端设备在不同的PUCCH组之间实现发送PUCCH的上行服务小区的动态切换。
在一个示例中，在多个上行服务小区包括第一PUCCH组内的第一上行服务小区和第二PUCCH组内的第二上行服务小区的情况下，切换指示信令用于指示终端设备由当前用于发送PUCCH的第一上行服务小区切换至第二上行服务小区，第一上行服务小区的PUCCH资源和第二上行服务小区的PUCCH资源处于激活状态；
其中，步骤203，可以具体执行为：在第二上行服务小区上接收PUCCH。
可以理解，优选的可以在终端设备确定当前用于发送PUCCH的第一上行服务小区进行空闲信道状态检测的结果为信道忙，无法在第一上行服务小区发送PUCCH，也就是说，网络设备一定时间内无法接收到相应的PUCCH时，则可以向终端设备发送切换指示信令，进而网络设备可以在终端设备从该第一上行服务小区切换到第二PUCCH组内PUCCH资源处于激活状态的第二上行服务小区后，于该第二上行服务小区即目标上行服 务小区上接收PUCCH。如此，实现发送PUCCH的上行服务小区的有效切换的同时，通过直接在处于激活状态的切换后的上行服务小区上接收PUCCH，可以提高PUCCH的发送效率。
其中，第一PUCCH组除第一上行服务小区外，还可以包括多个上行服务小区中的一个或多个；第二PUCCH组除第二上行服务小区外，还可以包括多个上行服务小区中的一个或多个。
在一个示例中，在第一PUCCH组包括CA模式下的主PUCCH组时，第二PUCCH组可以包括CA模式下的辅PUCCH组，反之也成立；或者在第一PUCCH组包括DC模式下的主小区组时，第二PUCCH组可以包括DC模式下的辅小区组，反之亦成立。
在一个示例中，在本公开实施例的PUCCH传输方法中，第一PUCCH组内和第二PUCCH组内分别仅有一个上行服务小区上配置了PUCCH资源，或者在每个PUCCH组内在同一时间仅有一个上行服务小区对应的PUCCH资源处于激活状态或可用状态，也就是说，每个PUCCH组内包括至少一个配置有PUCCH资源的上行服务小区。
在一个示例中，在第二上行服务小区上接收PUCCH的方案，可以具体执行为如下内容：
在第二上行服务小区上，接收第一PUCCH组对应的各下行服务小区对应的第一UCI和第二PUCCH组对应的各下行服务小区对应的第二UCI。
可以理解，通过在第二上行服务小区即目标上行服务小区上发送的PUCCH承载不同PUCCH组对应的各下行服务小区对应的上行控制信息，其中，各上行控制信息可以包括HARQ-ACK反馈信息或CSI报告。
在一个示例中，在第一UCI包括第一HARQ-ACK反馈信息，第二UCI包括第二HARQ-ACK反馈信息的情况下，在第二上行服务小区上， 接收第一PUCCH组对应的各下行服务小区对应的第一UCI和第二PUCCH组对应的各下行服务小区对应的第二UCI，可以具体执行为如下内容之一：
(1)在第二上行服务小区上，接收终端设备采用在第一PUCCH组内构建的第一HARQ-ACK码本方式发送的第一HARQ-ACK反馈信息、采用在第二PUCCH组内构建的第二HARQ-ACK码本方式发送的第二HARQ-ACK反馈信息。也就是说，按照切换用于发送PUCCH的上行服务小区(即PUCCH所在的上行服务小区)之前所采用的HARQ-ACK码本构建方式，分别在各自的PUCCH组内构建HARQ-ACK码本。
(2)在第二上行服务小区上，接收终端设备采用在由第一PUCCH组和第二PUCCH组构成的PUCCH合并组内构建的第三HARQ-ACK码本方式发送的第一HARQ-ACK反馈信息和第二HARQ-ACK反馈信息。也就是说，可以按照将不同的PUCCH组合并后对应的HARQ-ACK码本构建方式构建HARQ-ACK码本。
在一个示例中，分别配置有PUCCH资源的多个上行服务小区中的至少两个上行服务小区可以被分配在同一个PUCCH组中，如此，可以配置切换指示信令用于指示终端设备在同一PUCCH组内实现发送PUCCH的上行服务小区的切换。
在一个示例中，在多个上行服务小区包括目标PUCCH组内第三上行服务小区和第四上行服务小区的情况下，也就是说，目标PUCCH组内包括至少两个配置有PUCCH资源的上行服务小区，切换指示信令用于指示终端设备由当前用于发送PUCCH的第三上行服务小区切换至第四上行服务小区，目标PUCCH组为预配置的至少一个PUCCH组中的一个，目标PUCCH组内在同一时间仅有一个上行服务小区对应的PUCCH资源处于激活状态；
其中，步骤203，可以具体执行为：在第四上行服务小区上接收PUCCH。
可以理解，优选的网络设备可以在终端设备确定当前用于发送PUCCH的第三上行服务小区对应的信道忙，并从该第三上行服务小区切换到该目标PUCCH组内的第四上行服务小区后，于该第四上行服务小区即目标上行服务小区上接收PUCCH。如此，实现发送PUCCH的上行服务小区的有效切换。
在一个示例中，目标PUCCH组可以包括CA模式下的主PUCCH组或者辅PUCCH组。
在一个示例中，目标PUCCH组还可以包括DC模式下的主小区组或者辅小区组。
在一个示例中，在第四上行服务小区上接收PUCCH的方案，可以具体执行为如下内容：
在第四上行服务小区上，接收目标PUCCH组对应的各下行服务小区对应的第三UCI。
可以理解，通过在第四上行服务小区即目标上行服务小区上发送的PUCCH承载该目标PUCCH组对应的各下行服务小区对应的第三UCI，其中，第三UCI可以包括HARQ-ACK反馈信息或CSI报告。
在一个示例中，在第三UCI包括第三HARQ-ACK反馈信息的情况下，在第四上行服务小区上，接收目标PUCCH组对应的各下行服务小区对应的第三UCI的方案，可以具体执行为如下内容：
在第四上行服务小区上，接收终端设备采用在目标PUCCH组内构建的第三HARQ-ACK码本方式发送的第三HARQ-ACK反馈信息。也就是说，可以按照切换用于发送PUCCH的上行服务小区之前所采用的HARQ-ACK码本构建方式继续构建HARQ-ACK码本。
需要说明的是，切换指示信令用于指示实现PUCCH所在上行服务小区的切换时，并不限于在不同的PUCCH组之间的切换和在同一PUCCH组内的切换的方案。
在一个示例中，切换指示信令包括目标上行服务小区的小区索引号。如此，可以使得终端设备根据该小区索引号高效的确定在多个上行服务小区中确定目标上行服务小区。
具体实施例二
在该具体实施例二中，在步骤203之前，该方法还可以包括以下内容：
在多个上行服务小区上检测PUCCH；
将检测到PUCCH的上行服务小区确定为目标上行服务小区。
可以理解，网络设备可以通过盲检的方式确定终端设备用于发送PUCCH的目标上行服务小区。
在一个示例中，网络设备可以先在分别配置有PUCCH资源的多个上行服务小区中的每个上行服务小区上分别进行空闲信道状态检测，并将空闲信道状态检测的结果为空的上行服务小区作为用于确定接收PUCCH的目标上行服务小区的备选上行服务小区，以能够及时有效的接收PUCCH。
在本公开实施例的PUCCH传输方法的一个示例中，在备选上行服务小区有多个的情况下，目标上行服务小区包括以下之一：
备选上行服务小区中小区索引号最小的一个；
备选上行服务小区中信道条件最好的一个；
终端设备在备选上行服务小区中随机选择的一个。
可以理解，当目标上行服务小区为备选上行服务小区中小区索引号最小或信道条件最好的一个时，可以减小网络设备进行盲检的范围，可以进一步提高确定目标上行服务小区的效率。
在一个示例中，在备选上行服务小区有多个的情况下，还可以包括以下内容：
在备选上行服务小区中的每一个上接收PUCCH。
可以理解，当在多个分别配置有PUCCH资源的上行服务小区中，有多个信道条件良好可用于接收PUCCH时，可以在每一个上行服务小区上都接收PUCCH，实现PUCCH的重复接收，以提高PUCCH传输的可靠性。
