Description

通信方法和通信装置
本申请要求于2016年9月9日提交中国专利局，申请号为201610815964.0、发明名称为“通信方法和通信装置”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
本发明涉及通信技术领域，具体而言，涉及一种通信方法和一种通信装置。
背景技术
随着通信业务量的急剧增加，3GPP授权频谱显得越来越不足以提供更高的网络容量。因此3GPP提出了LAA（LTE Assisted Access，LTE辅助接入）的概念，用于借助LTE授权频谱的帮助来使用非授权频谱，LAA方案是基于载波聚合的功能来将LTE系统部署在非授权频段。
同时，非授权频谱可以有两种工作方式，一种是补充下行（SDL，Supplemental Downlink），即只有下行传输子帧；另一种是TDD模式，既包含下行子帧、也包含上行子帧。补充下行这种情况只能是借助载波聚合技术使用。而TDD模式除了可以借助载波聚合技术使用外，还可以借助DC （Dual Connectivity，双连通）使用，也可以独立使用。
现有方案只讨论了非授权频谱与LTE授权频谱使用载波聚合的方式进行工作时的各种问题，没有讨论使用双连接的方式进行工作时的问题。在很多情况下，非授权频谱部署的基站与授权频谱所在基站之间的连接是非理想的，只能使用双连接的方式。而在双连接的情况下，SeNB（Secondary eNB，辅基站）需要有一个PSCell （Primary Secondary cell，主辅助小区）来提供PCell（Primary cell，主小区）的部分功能，比如PDCCH（Physical Downlink Control Channel，物理下行控制信道）中的资源调度信令的发送，以及PUCCH（Physical Uplink Control Channel，物理上行控制信道）中UCI（Uplink Control Information，上行控制信息）的发送等。
在双连接中规定，PSCell是不能被跨载波调度的，只能自调度。并且在非授权频谱上，也可以部署工作在非授权载波上的PCell，即非授权频谱上的小区独立工作（standalone），以实现对通信的控制。但是，由于非授权频谱的占用需要采用先听后说（即Listen Before Talk，简称LBT）的机制，如果信道被其它设备占用，则无法正常发送资源调度信令以及上行UCI，导致上、下行数据或信令在非授权载波上无法正常发送，增大了通信时延，进而降低了系统的吞吐量。
发明内容
本发明正是基于上述技术问题至少之一，提出了一种新的通信方案，可以提高非授权频段上的主小区群组或主辅助小区群组上的信令或数据的发送概率，进而可以保证主小区群组或主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
有鉴于此，根据本发明的第一方面，提出了一种通信方法，包括：向每个终端配置至少一个服务小区，每个所述服务小区工作在一个非授权载波上；从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区或主辅助小区，以组成所述每个终端的主小区群组或主辅助小区群组；通过所述主小区群组或主辅助小区群组调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选出至少一个作为每个终端的主小区，以组成每个终端的主小区群组，进而通过该主小区群组来调度终端的上行传输和/或基站的下行传输时，是在非授权频段上部署主小区、且工作在非授权频段上的小区独立工作的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
当从工作在非授权频段上的至少一个服务小区中选出至少一个作为每个终端的主辅助小区，以组成每个终端的主辅助小区群组，进而通过该主辅助小区群组来调度终端的上行传输和/或基站的下行传输时，是在非授权频段和授权频段上进行双连接的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主辅助小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主辅助小区群组上的信令或数据的发送概率，进而可以保证主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
对于如何配置上述至少一个服务小区以及如何选择并组成每个终端的主小区群组或主辅助小区群组，本发明提出了如下三个方案：
方案一：
工作在授权频段上的主基站的主服务小区向所述每个终端在辅基站上配置所述至少一个服务小区，其中，所述主服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端在所述辅基站上的主辅助小区，以组成所述每个终端在所述辅基站上的主辅助小区群组。
方案一适用于非授权频段和授权频段以双连接的方式进行通信的场景，即由工作在授权频段上的主基站的主服务小区来向每个终端在辅基站上配置至少一个服务小区，并由主服务小区来选择并组成每个终端在辅基站上的主辅助小区群组。
方案二：
工作在授权频段上的主基站的主服务小区向所述每个终端在辅基站上配置工作在非授权频段上的主辅助服务小区，所述主辅助服务小区向所述每个终端在所述辅基站上配置工作在非授权频段上的0个或至少一个小区，所述0个或至少一个小区和所述主辅助服务小区组成所述至少一个服务小区，其中，所述主辅助服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端在所述辅基站上的主辅助小区，以组成所述每个终端在所述辅基站上的主辅助小区群组。
方案二也适用于非授权频段和授权频段以双连接的方式进行通信的场景，即由工作在授权频段上的主基站的主服务小区来向每个终端在辅基站上配置主辅助服务小区，进而由主辅助服务小区向每个终端在辅基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主辅助服务小区共同组成了上述至少一个服务小区，然后由主辅助服务小区来选择并组成每个终端在辅基站上的主辅助小区群组。
进一步地，在所述主辅助服务小区为多个的情况下，向所述每个终端配置所述0个或至少一个小区的配置信令由所述主辅助服务小区中的一个或多个发送。其中，所述的配置信令可以是RRC（Radio Resource Control，无线资源控制）信令。
方案三：
工作在非授权频段上的主基站的主服务小区向所述每个终端在所述主基站上配置工作在非授权频段上的0个或至少一个小区，所述0个或至少一个小区和所述主服务小区组成所述至少一个服务小区，其中，所述主服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区，以组成所述每个终端的主小区群组。
方案三适用于在非授权频段上部署主小区、且工作在非授权频段上的小区独立工作的通信场景，即由非授权频段上的主基站的主服务小区向每个终端在主基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主服务小区共同组成了上述至少一个服务小区，然后由主服务小区来选择并组成每个终端的主小区群组。
在上述任一技术方案中，优选地，通过所述主小区群组或主辅助小区群组调度所述每个终端的上行传输和/或基站的下行传输的步骤，具体包括：通过所述主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH（enhanced-Physical Downlink Control Channel，增强的物理下行控制信道）信道空闲的小区发送调度信令，以调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，由于在非授权频段上需要考虑到与其它系统（如Wi-Fi系统）的共存，即在非授权频段工作时需要引入LBT机制，因此需要通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令。
进一步地，该调度信令可以是上行调度信令，也可以是下行调度信令。其中，上行调度信令能够用于调度PUCCH、PUSCH（Physical Uplink Shared Channel，物理上行共享信道）和PRACH（Physical Random Access Channel，物理随机接入信道）；下行调度信令能够用于调度PDSCH（Physical Downlink Shared Channel，物理下行共享信道）。
在上述任一技术方案中，优选地，所述的通信方法还包括：若所述主小区群组或主辅助小区群组中的多个小区检测到PDCCH或e-PDCCH信道空闲，则在同一时间仅通过所述多个小区中的一个小区或多个小区的PDCCH或e-PDCCH发送所述调度信令。
在上述任一技术方案中，优选地，在所述调度信令用于调度PUCCH的情况下，对于相同的PUCCH发送内容，若所述主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲，则仅允许所述多个小区中的一个小区进行PUCCH发送内容的传输。
在该技术方案中，对于相同的PUCCH发送内容，即UCI，无需多个小区重复发送，因此在主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲时，可以仅允许其中的一个小区来进行PUCCH发送内容的传输。
在上述任一技术方案中，优选地，在所述调度信令用于调度PUCCH的情况下，根据待传输的上行控制信息的重要程度，控制所述主小区群组或主辅助小区群组中检测到PUCCH信道空闲的一个或多个小区传输上行控制信息，
其中，若所述主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低，则其传输的上行控制信息的重要程度越高。
在该技术方案中，通过在主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低时，其传输的上行控制信息的重要程度越高，使得对于重要程度较高的上行控制信息，可以通过通信环境较优的小区来进行传输。该技术方案尤其适用于PUCCH发送内容较多的场景，即可以按照上行控制信息的重要程度来分配小区进行传输，保证重要程度较高的上行控制信息能够得到优先传输。
在上述任一技术方案中，优选地，在所述调度信令用于调度PUSCH的情况下，对于相同的PUSCH发送内容，若所述至少一个服务小区中的多个服务小区的PUSCH均信道空闲，则仅允许所述多个服务小区中的一个服务小区进行PUSCH发送内容的传输。
在该技术方案中，对于相同的PUSCH发送内容，无需多个小区重复发送，因此在配置的至少一个服务小区中的多个服务小区的PUSCH均信道空闲时，可以仅允许其中的一个服务小区来进行PUSCH发送内容的传输。
在上述任一技术方案中，优选地，在所述调度信令用于调度PUSCH的情况下，对于不同的PUSCH发送内容，允许所述至少一个服务小区中检测到PUSCH空闲的多个服务小区一起进行传输。
在上述任一技术方案中，优选地，在所述调度信令用于调度PRACH的情况下，若所述主小区群组或主辅助小区群组中的多个小区的PRACH均信道空闲，则允许用户在所述多个小区上都发送随机接入前导码。
在该技术方案中，当用户在多个小区上都发送随机接入前导码时，若这多个小区属于同一个时间提前量组（Timing Advance Group，简称TAG），则仅在这多个小区中的一个小区上发送随机接入响应。
其中，在通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令时，有多种具体的发送方式，以下分别进行说明：
方式一：
发送调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，以向所述主小区群组或主辅助小区群组中的所有小区分配相同的时频资源。
在方式一中，发送调度信令的小区仅发送一个调度信令，这样向主小区群组或主辅助小区群组中的所有小区分配的时频资源都是相同的。
方式二：
发送调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，其中，所述调度信令用于向所述主小区群组或主辅助小区群组中的指定小区分配时频资源，所述主小区群组或主辅助小区群组中的其它小区的时频资源根据向所述指定小区分配的时频资源和预定义的偏移量获得。
在方式二中，虽然发送调度信令的小区仅发送了一个调度信令，但是向不同小区分配的时频资源是不相同的。
方式三：
发送调度信令的小区针对所述主小区群组或主辅助小区群组中的每个小区分别发送一个调度信令，以向所述每个小区分别分配时频资源。
在方式三中，为了向不同小区分配不同的时频资源，发送调度信令的小区针对每个小区都会发送一个调度信令。
在上述任一技术方案中，优选地，通过所述主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的任一小区发送所述调度信令的步骤，具体包括：
若所述任一小区在子帧n的起始位置进行16μs+M×9μs的one shot信道检测过程检测到PDCCH或e-PDCCH信道空闲，则在所述子帧n中的剩余时长内发送所述调度信令；或
若所述任一小区在子帧n之前的子帧的末尾位置进行16μs+M×9μs的one shot信道检测时检测到PDCCH或e-PDCCH信道空闲，则在所述子帧n中发送所述调度信令；
其中，M=1或2。
在上述任一技术方案中，优选地，所述主小区群组或主辅助小区群组中的任一小区进行PDCCH或e-PDCCH检测的过程，具体包括：
在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs之后，从0至竞争窗口之间选取随机数，其中，M为正整数；
在选取所述随机数后继续以9μs为单位进行信道检测，若检测到PDCCH或e-PDCCH信道忙，则所述随机数的值不变，并在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs时，所述随机数的值减1；若检测到PDCCH或e-PDCCH信道空闲，则所述随机数的值减1；
在所述随机数的值减为0时，确定能够占用PDCCH或e-PDCCH信道。
根据本发明的第二方面，还提出了一种通信装置，包括：配置单元，设置为向每个终端配置至少一个服务小区，每个所述服务小区工作在一个非授权载波上；选择单元，设置为从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区或主辅助小区，以组成所述每个终端的主小区群组或主辅助小区群组；通信控制单元，设置为通过所述主小区群组或主辅助小区群组调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选出至少一个作为每个终端的主小区，以组成每个终端的主小区群组，进而通过该主小区群组来调度终端的上行传输和/或基站的下行传输时，是非授权频段上的小区独立工作、且在非授权频段上部署主小区的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
当从工作在非授权频段上的至少一个服务小区中选出至少一个作为每个终端的主辅助小区，以组成每个终端的主辅助小区群组，进而通过该主辅助小区群组来调度终端的上行传输和/或基站的下行传输时，是在非授权频段和授权频段上进行双连接的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主辅助小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主辅助小区群组上的信令或数据的发送概率，进而可以保证主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
对于配置单元如何配置上述至少一个服务小区以及选择单元如何选择并组成每个终端的主小区群组或主辅助小区群组，本发明提出了如下三个方案：
方案一：

方案二：

方案二也适用于非授权频段和授权频段以双连接的方式进行通信的场景，即由工作在授权频段上的主基站的主服务小区来向每个终端在辅基站上配置主辅助服务小区，进而由主辅助服务小区向每个终端在辅基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主辅助服务小区共同组成了上述至少一个服务小区，然后由主辅助服务小区来选择并组成每个终端在辅基站上的主辅助小区群组。
进一步地，在所述主辅助服务小区为多个的情况下，向所述每个终端配置所述0个或至少一个小区的配置信令由所述主辅助服务小区中的一个或多个发送。其中，所述的配置信令可以是RRC信令。
方案三：

方案三适用于非授权频段上的小区独立工作、且在非授权频段上部署主小区的通信场景，即由非授权频段上的主基站的主服务小区向每个终端在主基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主服务小区共同组成了上述至少一个服务小区，然后由主服务小区来选择并组成每个终端的主小区群组。
在上述任一技术方案中，优选地，所述通信控制单元具体设置为：通过所述主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令，以调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，由于在非授权频段上需要考虑到与其它系统（如Wi-Fi系统）的共存，即在非授权频段工作时需要引入LBT机制，因此需要通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令。
进一步地，该调度信令可以是上行调度信令，也可以是下行调度信令。其中，上行调度信令能够用于调度PUCCH、PUSCH和PRACH；下行调度信令能够用于调度PDSCH。
在上述任一技术方案中，优选地，所述通信控制单元具体还设置为：若所述主小区群组或主辅助小区群组中的多个小区检测到PDCCH或e-PDCCH信道空闲，则在同一时间仅通过所述多个小区中的一个小区或多个小区的PDCCH或e-PDCCH发送所述调度信令。
在上述任一技术方案中，优选地，所述通信控制单元具体还设置为：在所述调度信令用于调度PUCCH的情况下，对于相同的PUCCH发送内容，若所述主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲，则仅允许所述多个小区中的一个小区进行PUCCH发送内容的传输。
在该技术方案中，对于相同的PUCCH发送内容，即UCI，无需多个小区重复发送，因此在主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲时，可以仅允许其中的一个小区来进行PUCCH发送内容的传输。
在上述任一技术方案中，优选地，所述通信控制单元具体还设置为：在所述调度信令用于调度PUCCH的情况下，根据待传输的上行控制信息的重要程度，控制所述主小区群组或主辅助小区群组中检测到PUCCH信道空闲的一个或多个小区传输上行控制信息，
其中，若所述主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低，则其传输的上行控制信息的重要程度越高。
在该技术方案中，通过在主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低时，其传输的上行控制信息的重要程度越高，使得对于重要程度较高的上行控制信息，可以通过通信环境较优的小区来进行传输。该技术方案尤其适用于PUCCH发送内容较多的场景，即可以按照上行控制信息的重要程度来分配小区进行传输，保证重要程度较高的上行控制信息能够得到优先传输。
在上述任一技术方案中，优选地，所述通信控制单元具体还设置为：在所述调度信令用于调度PUSCH的情况下，对于相同的PUSCH发送内容，若所述至少一个服务小区中的多个服务小区的PUSCH均信道空闲，则仅允许所述多个服务小区中的一个服务小区进行PUSCH发送内容的传输。
在该技术方案中，对于相同的PUSCH发送内容，无需多个小区重复发送，因此在配置的至少一个服务小区中的多个服务小区的PUSCH均信道空闲时，可以仅允许其中的一个服务小区来进行PUSCH发送内容的传输。
在上述任一技术方案中，优选地，所述通信控制单元具体还设置为：在所述调度信令用于调度PUSCH的情况下，对于不同的PUSCH发送内容，允许所述至少一个服务小区中检测到PUSCH空闲的多个服务小区一起进行传输。
在上述任一技术方案中，优选地，所述通信控制单元具体还设置为：在所述调度信令用于调度PRACH的情况下，若所述主小区群组或主辅助小区群组中的多个小区的PRACH均信道空闲，则允许用户在所述多个小区上都发送随机接入前导码。
在该技术方案中，当用户在多个小区上都发送随机接入前导码时，若这多个小区属于同一个时间提前量组，则仅在这多个小区中的一个小区上发送随机接入响应。
其中，在通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令时，有多种具体的发送方式，以下分别进行说明：
方式一：
发送所述调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，以向所述主小区群组或主辅助小区群组中的所有小区分配相同的时频资源。
在方式一中，发送调度信令的小区仅发送一个调度信令，这样向主小区群组或主辅助小区群组中的所有小区分配的时频资源都是相同的。
方式二：
发送所述调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，其中，所述调度信令用于向所述主小区群组或主辅助小区群组中的指定小区分配时频资源，所述主小区群组或主辅助小区群组中的其它小区的时频资源根据向所述指定小区分配的时频资源和预定义的偏移量获得。
在方式二中，虽然发送调度信令的小区仅发送了一个调度信令，但是向不同小区分配的时频资源是不相同的。
方式三：
发送所述调度信令的小区针对所述主小区群组或主辅助小区群组中的每个小区分别发送一个调度信令，以向所述每个小区分别分配时频资源。
在方式三中，为了向不同小区分配不同的时频资源，发送调度信令的小区针对每个小区都会发送一个调度信令。

若所述任一小区在子帧n的起始位置进行16μs+M×9μs的one shot信道检测过程检测到PDCCH或e-PDCCH信道空闲，则通过所述任一小区在所述子帧n中的剩余时长内发送所述调度信令；或
若所述任一小区在子帧n之前的子帧的末尾位置进行16μs+M×9μs的one shot信道检测时检测到PDCCH或e-PDCCH信道空闲，则通过所述任一小区在所述子帧n中发送所述调度信令；
其中，M=1或2。

在选取所述随机数后继续以9μs为单位进行信道检测，若检测到PDCCH或e-PDCCH信道忙，则所述随机数的值不变，并在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs时，所述随机数的值减1；若检测到PDCCH或e-PDCCH信道空闲，则所述随机数的值减1；

在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选择组成主小区群组时，是非授权频段独立工作、且在非授权频段上部署主小区的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主小区群组的调度来进行上行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
当从工作在非授权频段上的至少一个服务小区中选择组成主辅助小区群组时，是在非授权频段和授权频段上进行双连接的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主辅助小区群组的调度来进行上行传输，可以提高每个终端的主辅助小区群组上的信令或数据的发送概率，进而可以保证主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。

在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选择组成主小区群组时，是非授权频段独立工作、且在非授权频段上部署主小区的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主小区群组的调度来进行上行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。

在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。
图1示出了根据本发明的第一个实施例的通信方法的示意流程图。
如图1所示，根据本发明的第一个实施例的通信方法，包括以下步骤：
步骤S10，向每个终端配置至少一个服务小区，每个所述服务小区工作在一个非授权载波上。
步骤S12，从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区或主辅助小区，以组成所述每个终端的主小区群组或主辅助小区群组。
对于步骤S10中如何配置上述至少一个服务小区以及步骤S12中如何选择并组成每个终端的主小区群组或主辅助小区群组，本发明提出了如下三个方案：
方案一：
工作在授权频段上的主基站的主服务小区向所述每个终端在辅基站上配置所述至少一个服务小区，其中，所述主服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端在所述辅基站上的主辅助小区，以组成所述每个终端在所述辅基站上的主辅助小区群组。
方案一适用于非授权频段和授权频段以双连接的方式进行通信的场景，即由工作在授权频段上的主基站的主服务小区来向每个终端在辅基站上配置至少一个服务小区，并由主服务小区来选择并组成每个终端在辅基站上的主辅助小区群组。
方案二：
工作在授权频段上的主基站的主服务小区向所述每个终端在辅基站上配置工作在非授权频段上的主辅助服务小区，所述主辅助服务小区向所述每个终端在所述辅基站上配置工作在非授权频段上的0个或至少一个小区，所述0个或至少一个小区和所述主辅助服务小区组成所述至少一个服务小区，其中，所述主辅助服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端在所述辅基站上的主辅助小区，以组成所述每个终端在所述辅基站上的主辅助小区群组。
方案二也适用于非授权频段和授权频段以双连接的方式进行通信的场景，即由工作在授权频段上的主基站的主服务小区来向每个终端在辅基站上配置主辅助服务小区，进而由主辅助服务小区向每个终端在辅基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主辅助服务小区共同组成了上述至少一个服务小区，然后由主辅助服务小区来选择并组成每个终端在辅基站上的主辅助小区群组。
进一步地，在所述主辅助服务小区为多个的情况下，向所述每个终端配置所述0个或至少一个小区的配置信令由所述主辅助服务小区中的一个或多个发送。其中，所述的配置信令可以是RRC信令。
方案三：
工作在非授权频段上的主基站的主服务小区向所述每个终端在所述主基站上配置工作在非授权频段上的0个或至少一个小区，所述0个或至少一个小区和所述主服务小区组成所述至少一个服务小区，其中，所述主服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区，以组成所述每个终端的主小区群组。
方案三适用于非授权频段上的小区独立工作、且在非授权频段上部署主小区的通信场景，即由非授权频段上的主基站的主服务小区向每个终端在主基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主服务小区共同组成了上述至少一个服务小区，然后由主服务小区来选择并组成每个终端的主小区群组。
图1所示的通信方法还包括：
步骤S14，通过所述主小区群组或主辅助小区群组调度所述每个终端的上行传输和/或基站的下行传输。
在本发明的一个实施例中，步骤S14具体包括：通过所述主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令，以调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，由于在非授权频段上需要考虑到与其它系统（如Wi-Fi系统）的共存，即在非授权频段工作时需要引入LBT机制，因此需要通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令。
进一步地，该调度信令可以是上行调度信令，也可以是下行调度信令。其中，上行调度信令能够用于调度PUCCH、PUSCH和PRACH；下行调度信令能够用于调度PDSCH。
进一步地，若所述主小区群组或主辅助小区群组中的多个小区检测到PDCCH或e-PDCCH信道空闲，则在同一时间仅通过所述多个小区中的一个小区或多个小区的PDCCH或e-PDCCH发送所述调度信令。
以下详细说明上述的调度信令对PUCCH、PUSCH和PRACH的调度过程：
1、在调度信令用于调度PUCCH的情况下：
（1）对于相同的PUCCH发送内容，若所述主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲，则仅允许所述多个小区中的一个小区进行PUCCH发送内容的传输。
由于相同的PUCCH发送内容，即UCI，无需多个小区重复发送，因此在主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲时，可以仅允许其中的一个小区来进行PUCCH发送内容的传输。
（2）在调度信令用于调度PUCCH的情况下，根据待传输的上行控制信息的重要程度，控制所述主小区群组或主辅助小区群组中检测到PUCCH信道空闲的一个或多个小区传输上行控制信息，
其中，若所述主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低，则其传输的上行控制信息的重要程度越高。
具体地，通过在主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低时，其传输的上行控制信息的重要程度越高，使得对于重要程度较高的上行控制信息，可以通过通信环境较优的小区来进行传输。该技术方案尤其适用于PUCCH发送内容较多的场景，即可以按照上行控制信息的重要程度来分配小区进行传输，保证重要程度较高的上行控制信息能够得到优先传输。
2、在调度信令用于调度PUSCH的情况下：
（1）对于相同的PUSCH发送内容，若所述至少一个服务小区中的多个服务小区的PUSCH均信道空闲，则仅允许所述多个服务小区中的一个服务小区进行PUSCH发送内容的传输。
由于相同的PUSCH发送内容无需多个小区重复发送，因此在配置的至少一个服务小区中的多个服务小区的PUSCH均信道空闲时，可以仅允许其中的一个服务小区来进行PUSCH发送内容的传输。
（2）对于不同的PUSCH发送内容，允许所述至少一个服务小区中检测到PUSCH空闲的多个服务小区一起进行传输。
3、在调度信令用于调度PRACH的情况下：
若主小区群组或主辅助小区群组中的多个小区的PRACH均信道空闲，则允许用户在所述多个小区上都发送随机接入前导码。
进一步地，当用户在多个小区上都发送随机接入前导码时，若这多个小区属于同一个时间提前量组，则仅在这多个小区中的一个小区上发送随机接入响应。
在通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令时，有多种具体的发送方式，以下分别进行说明：
方式一：
发送调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，以向所述主小区群组或主辅助小区群组中的所有小区分配相同的时频资源。
在方式一中，发送调度信令的小区仅发送一个调度信令，这样向主小区群组或主辅助小区群组中的所有小区分配的时频资源都是相同的。
方式二：
发送调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，其中，所述调度信令用于向所述主小区群组或主辅助小区群组中的指定小区分配时频资源，所述主小区群组或主辅助小区群组中的其它小区的时频资源根据向所述指定小区分配的时频资源和预定义的偏移量获得。
在方式二中，虽然发送调度信令的小区仅发送了一个调度信令，但是向不同小区分配的时频资源是不相同的。
方式三：
发送调度信令的小区针对所述主小区群组或主辅助小区群组中的每个小区分别发送一个调度信令，以向所述每个小区分别分配时频资源。
在方式三中，为了向不同小区分配不同的时频资源，发送调度信令的小区针对每个小区都会发送一个调度信令。
其中，主小区群组或主辅助小区群组中的任一小区进行PDCCH或e-PDCCH信道检测的机制主要包括如下两个：
信道检测机制一：
若任一小区在子帧n的起始位置进行16μs+M×9μs的one shot信道检测过程检测到PDCCH或e-PDCCH信道空闲，则在所述子帧n中的剩余时长内发送所述调度信令；或
若任一小区在子帧n之前的子帧的末尾位置进行16μs+M×9μs的one shot信道检测时检测到PDCCH或e-PDCCH信道空闲，则在子帧n中发送所述调度信令；
其中，M=1或2。
信道检测机制二：
在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs之后，从0至竞争窗口之间选取随机数，其中，M为正整数；
在选取所述随机数后继续以9μs为单位进行信道检测，若检测到PDCCH或e-PDCCH信道忙，则所述随机数的值不变，并在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs时，所述随机数的值减1；若检测到PDCCH或e-PDCCH信道空闲，则所述随机数的值减1；
在所述随机数的值减为0时，确定能够占用PDCCH或e-PDCCH信道。
在图1所示的通信方案中，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主小区群组或主辅助小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主小区群组或主辅助小区群组上的信令或数据的发送概率，进而可以保证主小区群组或主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
图2示出了根据本发明的第一个实施例的通信装置的示意框图。
如图2所示，根据本发明的第一个实施例的通信装置200，包括：配置单元202、选择单元204和通信控制单元206。
其中，配置单元202设置为向每个终端配置至少一个服务小区，每个所述服务小区工作在一个非授权载波上；选择单元204设置为从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区或主辅助小区，以组成所述每个终端的主小区群组或主辅助小区群组；通信控制单元206设置为通过所述主小区群组或主辅助小区群组调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选出至少一个作为每个终端的主小区，以组成每个终端的主小区群组，进而通过该主小区群组来调度终端的上行传输和/或基站的下行传输时，是非授权频段上的小区独立工作、且在非授权频段上部署主小区的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
当从工作在非授权频段上的至少一个服务小区中选出至少一个作为每个终端的主辅助小区，以组成每个终端的主辅助小区群组，进而通过该主辅助小区群组来调度终端的上行传输和/或基站的下行传输时，是在非授权频段和授权频段上进行双连接的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此通过由主辅助小区群组来调度每个终端的上行传输和/或基站的下行传输，可以提高每个终端的主辅助小区群组上的信令或数据的发送概率，进而可以保证主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
对于配置单元202如何配置上述至少一个服务小区以及选择单元204如何选择并组成每个终端的主小区群组或主辅助小区群组，本发明提出了如下三个方案：

方案二也适用于非授权频段和授权频段以双连接的方式进行通信的场景，即由工作在授权频段上的主基站的主服务小区来向每个终端在辅基站上配置主辅助服务小区，进而由主辅助服务小区向每个终端在辅基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主辅助服务小区共同组成了上述至少一个服务小区，然后由主辅助服务小区来选择并组成每个终端在辅基站上的主辅助小区群组。
进一步地，在所述主辅助服务小区为多个的情况下，向所述每个终端配置所述0个或至少一个小区的配置信令由所述主辅助服务小区中的一个或多个发送。其中，所述的配置信令可以是RRC信令。
方案三：
所述配置单元202具体设置为，通过工作在非授权频段上的主基站的主服务小区向所述每个终端在所述主基站上配置工作在非授权频段上的0个或至少一个小区，所述0个或至少一个小区和所述主服务小区组成所述至少一个服务小区；所述选择单元204具体设置为，通过所述主服务小区从所述至少一个服务小区中选出至少一个作为所述每个终端的主小区，以组成所述每个终端的主小区群组。
方案三适用于非授权频段上的小区独立工作、且在非授权频段上部署主小区的通信场景，即由非授权频段上的主基站的主服务小区向每个终端在主基站上配置工作在非授权频段上的0个或至少一个小区，这0个或至少一个小区和主服务小区共同组成了上述至少一个服务小区，然后由主服务小区来选择并组成每个终端的主小区群组。
在上述任一技术方案中，优选地，所述通信控制单元206具体设置为：通过所述主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令，以调度所述每个终端的上行传输和/或基站的下行传输。
在该技术方案中，由于在非授权频段上需要考虑到与其它系统（如Wi-Fi系统）的共存，即在非授权频段工作时需要引入LBT机制，因此需要通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令。
进一步地，该调度信令可以是上行调度信令，也可以是下行调度信令。其中，上行调度信令能够用于调度PUCCH、PUSCH和PRACH；下行调度信令能够用于调度PDSCH。
进一步地，所述通信控制单元206具体还设置为：若所述主小区群组或主辅助小区群组中的多个小区检测到PDCCH或e-PDCCH信道空闲，则在同一时间仅通过所述多个小区中的一个小区或多个小区的PDCCH或e-PDCCH发送所述调度信令。
以下详细说明上述的调度信令对PUCCH、PUSCH和PRACH的调度过程：
1、通信控制单元206具体还设置为：在所述调度信令用于调度PUCCH的情况下，对于相同的PUCCH发送内容，若所述主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲，则仅允许所述多个小区中的一个小区进行PUCCH发送内容的传输。
在该技术方案中，对于相同的PUCCH发送内容，即UCI，无需多个小区重复发送，因此在主小区群组或主辅助小区群组中的多个小区的PUCCH均信道空闲时，可以仅允许其中的一个小区来进行PUCCH发送内容的传输。
2、通信控制单元206具体还设置为：在所述调度信令用于调度PUCCH的情况下，根据待传输的上行控制信息的重要程度，控制所述主小区群组或主辅助小区群组中检测到PUCCH信道空闲的一个或多个小区传输上行控制信息，
其中，若所述主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低，则其传输的上行控制信息的重要程度越高。
在该技术方案中，通过在主小区群组或主辅助小区群组中的小区的RSRP/RSRQ越高和/或信道占用率越低时，其传输的上行控制信息的重要程度越高，使得对于重要程度较高的上行控制信息，可以通过通信环境较优的小区来进行传输。该技术方案尤其适用于PUCCH发送内容较多的场景，即可以按照上行控制信息的重要程度来分配小区进行传输，保证重要程度较高的上行控制信息能够得到优先传输。
3、通信控制单元206具体还设置为：在所述调度信令用于调度PUSCH的情况下，对于相同的PUSCH发送内容，若所述至少一个服务小区中的多个服务小区的PUSCH均信道空闲，则仅允许所述多个服务小区中的一个服务小区进行PUSCH发送内容的传输。
在该技术方案中，对于相同的PUSCH发送内容，无需多个小区重复发送，因此在配置的至少一个服务小区中的多个服务小区的PUSCH均信道空闲时，可以仅允许其中的一个服务小区来进行PUSCH发送内容的传输。
4、通信控制单元206具体还设置为：在所述调度信令用于调度PUSCH的情况下，对于不同的PUSCH发送内容，允许所述至少一个服务小区中检测到PUSCH空闲的多个服务小区一起进行传输。
5、通信控制单元206具体还设置为：在所述调度信令用于调度PRACH的情况下，若所述主小区群组或主辅助小区群组中的多个小区的PRACH均信道空闲，则允许用户在所述多个小区上都发送随机接入前导码。
在该技术方案中，当用户在多个小区上都发送随机接入前导码时，若这多个小区属于同一个时间提前量组，则仅在这多个小区中的一个小区上发送随机接入响应。
在通过主小区群组或主辅助小区群组中检测到PDCCH或e-PDCCH信道空闲的小区发送调度信令时，有多种具体的发送方式，以下分别进行说明：
方式一：
发送所述调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，以向所述主小区群组或主辅助小区群组中的所有小区分配相同的时频资源。
在方式一中，发送调度信令的小区仅发送一个调度信令，这样向主小区群组或主辅助小区群组中的所有小区分配的时频资源都是相同的。
方式二：
发送所述调度信令的小区针对所述主小区群组或主辅助小区群组中的所有小区仅发送一个调度信令，其中，所述调度信令用于向所述主小区群组或主辅助小区群组中的指定小区分配时频资源，所述主小区群组或主辅助小区群组中的其它小区的时频资源根据向所述指定小区分配的时频资源和预定义的偏移量获得。
在方式二中，虽然发送调度信令的小区仅发送了一个调度信令，但是向不同小区分配的时频资源是不相同的。
方式三：
发送所述调度信令的小区针对所述主小区群组或主辅助小区群组中的每个小区分别发送一个调度信令，以向所述每个小区分别分配时频资源。
在方式三中，为了向不同小区分配不同的时频资源，发送调度信令的小区针对每个小区都会发送一个调度信令。
其中，主小区群组或主辅助小区群组中的任一小区进行PDCCH或e-PDCCH信道检测的机制主要包括如下两个：
信道检测机制一：
若任一小区在子帧n的起始位置进行16μs+M×9μs的one shot信道检测过程检测到PDCCH或e-PDCCH信道空闲，则在所述子帧n中的剩余时长内发送所述调度信令；或
若任一小区在子帧n之前的子帧的末尾位置进行16μs+M×9μs的one shot信道检测时检测到PDCCH或e-PDCCH信道空闲，则在子帧n中发送所述调度信令；
其中，M=1或2。
信道检测机制二：
在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs之后，从0至竞争窗口之间选取随机数，其中，M为正整数；
在选取所述随机数后继续以9μs为单位进行信道检测，若检测到PDCCH或e-PDCCH信道忙，则所述随机数的值不变，并在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs时，所述随机数的值减1；若检测到PDCCH或e-PDCCH信道空闲，则所述随机数的值减1；
在所述随机数的值减为0时，确定能够占用PDCCH或e-PDCCH信道。

如图3所示，根据本发明的第二个实施例的通信方法，包括以下步骤：
步骤S30，终端确定工作在非授权载波上的主小区群组或主辅助小区群组，其中，所述主小区群组或主辅助小区群组是从工作在非授权载波上的至少一个服务小区中进行选择而组成的，每个所述服务小区工作在一个非授权载波上。
步骤S32，监测所述主小区群组或主辅助小区群组中所有小区的调度信令。

在本发明的一个实施例中，步骤S34具体包括：在所述调度信令用于调度PUCCH和/或PRACH时，若检测到所述主小区群组或主辅助小区群组中的多个小区的PUCCH信道空闲和/或PRACH信道空闲，则通过所述多个小区中的至少一个小区的PUCCH和/或PRACH进行上行传输。
优选地，可以从PUCCH信道空闲和/或PRACH信道空闲的多个小区中选择RSRP/RSRQ较大和/或信道占用率较低的一个或多个小区来进行上行传输。
在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选择组成主小区群组时，是非授权频段独立工作、且在非授权频段上部署主小区的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主小区群组的调度来进行上行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
当从工作在非授权频段上的至少一个服务小区中选择组成主辅助小区群组时，是在非授权频段和授权频段上进行双连接的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主辅助小区群组的调度来进行上行传输，可以提高每个终端的主辅助小区群组上的信令或数据的发送概率，进而可以保证主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
其中，终端确定工作在非授权载波上的主辅助小区群组可以是通过接收授权频段上的主基站的主服务小区或非授权频段上的辅基站的主辅助小区发送的通知信令来确定的。
其中，图3所示的通信方法的执行主体可以是终端。
图4示出了根据本发明的第二个实施例的通信装置的示意框图。
如图4所示，根据本发明的第二个实施例的通信装置400，包括：确定单元402、监测单元404和处理单元406。
其中，确定单元402设置为确定工作在非授权载波上的主小区群组或主辅助小区群组，其中，所述主小区群组或主辅助小区群组是从工作在非授权载波上的至少一个服务小区中进行选择而组成的，每个所述服务小区工作在一个非授权载波上；监测单元404，设置为监测所述主小区群组或主辅助小区群组中所有小区的调度信令；处理单元406设置为基于所述主小区群组或主辅助小区群组中的调度信令进行上行传输。
在该技术方案中，当从工作在非授权频段上的至少一个服务小区中选择组成主小区群组时，是非授权频段独立工作、且在非授权频段上部署主小区的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主小区群组的调度来进行上行传输，可以提高每个终端的主小区群组上的信令或数据的发送概率，进而可以保证主小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
当从工作在非授权频段上的至少一个服务小区中选择组成主辅助小区群组时，是在非授权频段和授权频段上进行双连接的通信场景，由于在非授权频段上不能连续占用信道，即存在信道检测机制，因此终端通过基于主辅助小区群组的调度来进行上行传输，可以提高每个终端的主辅助小区群组上的信令或数据的发送概率，进而可以保证主辅助小区群组能够及时有效地发送和接收必要的信令或数据，满足了通信的时延和效率要求。
其中，确定单元402确定工作在非授权载波上的主辅助小区群组可以是通过接收授权频段上的主基站的主服务小区或非授权频段上的辅基站的主辅助小区发送的通知信令来确定的。
进一步地，所述处理单元406具体设置为：在所述调度信令用于调度PUCCH和/或PRACH时，若检测到所述主小区群组或主辅助小区群组中的多个小区的PUCCH信道空闲和/或PRACH信道空闲，则通过所述多个小区中的至少一个小区的PUCCH和/或PRACH进行上行传输。
优选地，可以从PUCCH信道空闲和/或PRACH信道空闲的多个小区中选择RSRP/RSRQ较大和/或信道占用率较低的一个或多个小区来进行上行传输。
综上，本发明的技术方案主要是通过工作在非授权频段上的主小区群组（PCell Group）或主辅助小区群组（PSCell Group）来提高信令或数据的发送概率，如上行调度信令、下行调度信令、上行控制信息等，满足了通信的时延和效率要求。
具体地，主要分为以下几个方面：
一、PCell Group或PSCell Group的配置。
1、PCell Group的配置：
工作在非授权频段上的主基站的PCell向每个终端在主基站上配置工作在非授权频段上的0个或至少一个Cell，进而PCell从这0个或至少一个Cell中挑选出0个或至少一个，并与PCell一起组成每个终端的PCell Group。
其中，至少一个Cell中的每个Cell工作在一个非授权载波上，譬如在非授权载波1上配置了Cell#1，在非授权载波2上配置了Cell#2，在非授权载波3上配置了Cell#3……在非授权载波M上配置了Cell#M，进而PCell从中挑选出0个或至少一个Cell与PCell共同组成每个终端的PCell Group。PCell Group中的小区数量可以有一个上限值，如最大为2、3或其它值等。对于不同的用户来说，其PCell Group是独立的，即不同用户的PCell Group可以是一样的也可以是不一样的。
2、PSCell Group的配置，具体分为两种配置方案：
方案1：
工作在授权频段上的主基站（即MeNB）的PCell向每个终端在辅基站（即SeNB）上配置工作在非授权频段上的至少一个服务小区，进而PCell从该至少一个服务小区中选出至少一个作为每个终端在SeNB上的PSCell，以组成每个终端在辅基站上的PSCell Group。
其中，至少一个服务小区中的每个服务小区工作在一个非授权载波上，譬如在非授权载波1上配置了SCell#1，在非授权载波2上配置了SCell#2，在非授权载波3上配置了SCell#3……在非授权载波M上配置了SCell#M，进而PCell从中挑选出至少一个SCell组成每个终端的PSCell Group。PSCell Group中的小区数量可以有一个上限值，如最大为2、3或其它值等。对于不同的用户来说，其PSCell Group是独立的，即不同用户的PSCell Group可以是一样的也可以是不一样的。
方案2：
工作在授权频段上的主基站（即MeNB）的PCell向每个终端在辅基站（即SeNB）上配置工作在非授权频段上的PSCell，进而PSCell向每个终端在SeNB上配置工作在非授权频段上的0个或至少一个小区，进而PSCell从这0个或至少一个小区中挑选出0个或至少一个，并与PSCell一起组成每个终端的PSCell Group。
其中，至少一个小区中的每个小区工作在一个非授权载波上，譬如在非授权载波1上配置了SCell#1，在非授权载波2上配置了SCell#2，在非授权载波3上配置了SCell#3……在非授权载波M上配置了SCell#M，进而PSCell从中挑选出0个或至少一个SCell与PSCell共同组成每个终端的PSCell Group。PSCell Group中的小区数量可以有一个上限值，如最大为2、3或其它值等。对于不同的用户来说，其PSCell Group是独立的，即不同用户的PSCell Group可以是一样的也可以是不一样的。
3、选择PSCell Group中的PSCell的一种具体方式：
首先进行SCell的选择，以组成SCell Group，进而从SCell Group中进一步选择一个或多个作为PSCell，以构成PSCell Group。
其中，在进行SCell的选择时，可以采用LTE的Event A3、Event A4和Event A5等来选择。
譬如，在采用Event A3时，若邻小区的服务质量比当前服务小区的服务质量高时，将邻小区加入SCell Group；在采用Event A4时，若邻小区的服务质量高于一定门限值时，将邻小区加入SCell Group；在采用Event A5时，若服务小区的服务质量低于一个门限值，而邻小区的服务指令高于一个门限值时，将邻小区加入SCell Group。
4、PSCell Group内的PSCell的添加、去除和替换：
（1）PSCell的添加。
将所有的SCell进行降序排序，排序的准则为：RSRP/RSRQ由大到小和/或信道占用率由低到高的顺序。排在最前面的且满足预定条件的SCell依次选为PSCell#1、PSCell#2……，直到选择的PSCell到达最大数目或者所有的SCell选择完为止。其中，预定条件是指RSRP/RSRQ大于一个门限值，和/或信道占用率小于一个门限值。
（2）PSCell的去除。
当PSCell Group内的某个PSCell的RSRP/RSRQ小于某个门限值，和/或信道占用率大于一个门限值时，将该PSCell从PSCell Group内去除。
（3）PSCell的替换
方式一：若某个SCell的RSRP/RSRQ比PSCell Group内的一个PSCell的RSRP/RSRQ高一定值，和/或某个SCell的信道占用率比该PSCell的信道占用率低一定值，则通过该SCell替换该PSCell。
方式二：若某个SCell的RSRP/RSRQ高于门限值1，和/或信道占用率低于门限值2；且PSCell Group内的一个PSCell的RSRP/RSRQ低于门限值3，和/或信道占用率高于门限值4，则通过该SCell替换该PSCell。
5、PCell Group内的PCell的添加、去除和替换的方案类似于PSCell Group内的PSCell的添加、去除和替换的方案，不再赘述。
二、PCell Group或PSCell Group的调度过程。
1、PCell Group中的每个PCell独立进行LBT信道检测（不同PCell可以使用相同的LBT机制，也可以使用不同的LBT机制），若多个PCell信道检测空闲，那么同一时间只需要一个PCell进行调度信令的发送。其中，发送调度信令的PCell的优先级可以预先定义好，譬如编号最小的PCell优先发送调度信令。在此，编号最小的PCell表示的是RSRP/RSRQ最大和/或信道占用率最低的PCell。
类似地，PSCell Group中的每个PSCell独立进行LBT信道检测（不同PSCell可以使用相同的LBT机制，也可以使用不同的LBT机制），若多个PSCell信道检测空闲，那么同一时间只需要一个PSCell进行调度信令的发送。其中，发送调度信令的PSCell的优先级可以预先定义好，譬如编号最小的PSCell优先发送调度信令。在此，编号最小的PSCell表示的是RSRP/RSRQ最大和/或信道占用率最低的PSCell。
其中，上述的调度信令可以是上行调度信令，也可以是下行调度信令。并且上行调度信令能够用于调度PUCCH、PUSCH和PRACH；下行调度信令能够用于调度PDSCH。
2、在上述的调度信令为上行调度信令时，以下详细说明该上行调度信令对PUCCH、PUSCH和PRACH的调度过程：
（1）调度PUCCH：
情况一：对于同样的PUCCH发送内容
若PCell Group中的多个PCell的PUCCH信道都空闲，则只允许一个PCell进行PUCCH发送内容的传输。其中，可以通过编号最小的PCell来传输PUCCH发送内容。其中，编号最小的PCell表示的是RSRP/RSRQ最大和/或信道占用率最低的PCell。
类似地，若PSCell Group中的多个PSCell的PUCCH信道都空闲，则只允许一个PSCell进行PUCCH发送内容的传输。其中，可以通过编号最小的PSCell来传输PUCCH发送内容。其中，编号最小的PSCell表示的是RSRP/RSRQ最大和/或信道占用率最低的PSCell。
情况二：对于不同的PUCCH发送内容
当PUCCH发送内容较多时，在传统载波聚合的情况下是有舍弃的。在本发明的技术方案中，若PCell Group中的多个PCell都检测到上行信道空闲，则通过多个PCell来共同传输PUCCH发送内容，并且PCell编号最低的发送最不能舍弃的UCI，依次排序，编号最高的PCell发送最先可以舍弃的UCI。其中，编号最小的PCell表示的是RSRP/RSRQ最大和/或信道占用率最低的PCell，而编号最大的PCell表示的是RSRP/RSRQ最小和/或信道占用率最高的PCell。
类似地，当PUCCH发送内容较多时，若PSCell Group中的多个PSCell都检测到上行信道空闲，则通过多个PSCell来共同传输PUCCH发送内容，并且PSCell编号最低的发送最不能舍弃的UCI，依次排序，编号最高的PSCell发送最先可以舍弃的UCI。其中，编号最小的PSCell表示的是RSRP/RSRQ最大和/或信道占用率最低的PSCell，而编号最大的PSCell表示的是RSRP/RSRQ最小和/或信道占用率最高的PSCell。
针对采用PCell Group和PSCell Group中的任一方案，当PUCCH发送内容（即UCI）较多时，UCI主要包含载波聚合的多个小区的CSI（Channel State Information，信道状态信息）、RI（Rank Indication，秩指示）、PMI（Pre-coding Matrix Indicator，预编码矩阵指示），HARQ（Hybrid Automatic Repeat Request，混合自动重传请求） ACK/NACK和SR（Scheduling Request，调度请求）等信息，而这些信息还需要区分不同的RANK、宽带CSI或窄带CSI、周期性CSI和非周期性CSI等。3GPP标准文件TS 36.213中给出了多个UCI需要一起发送时，如果PUCCH资源不够，那么有些不重要的UCI将会丢弃，其中也给出了丢弃的优先级。本发明中UCI舍弃的规则可以参考TS36.213.
（2）调度PUSCH：
当上行调度信令用于调度PUSCH时，该上行调度信令能够调度所有小区的PUSCH。这里的所有小区指的是与发送上行调度信令的小区同属于一个基站的所有小区。
对于同样的PUSCH发送内容，若多个小区的PUSCH信道都空闲，则只允许其中的一个小区进行PUSCH发送内容的传输。
对于不同的PUSCH发送内容，若PUSCH发送内容较多且多个小区的PUSCH信道都空闲，则允许多个小区共同进行PUSCH发送内容的传输。
（3）调度PRACH：
若PCell Group中的多个PCell的PUCCH信道都空闲，则用户可以在这多个PCell中都发送RA。
类似地，若PSCell Group中的多个PSCell的PUCCH信道都空闲，则用户可以在这多个PSCell中都发送RA。
3、PDCCH或e-PDCCH中调度信令的发送方式：
方式一：
针对PCell Group仅发送一个调度信令，这样向PCell Group中的每个PCell分配的时域资源和频域资源都相同。
类似地，针对PSCell Group仅发送一个调度信令，这样向PSCell Group中的每个PSCell分配的时域资源和频域资源都相同。
方式二：
针对PCell Group仅发送一个调度信令，这个调度信令用于向PCell Group中指定的一个PCell分配时域资源和频域资源，而向PCell Group中的其它PCell分配的时域资源和频域资源基于此按照一定的规律进行偏移。方式二中，虽然仅发送了一个调度信令，但是向PCell Group中的不同小区分配的时频资源是不相同的。
类似地，针对PSCell Group仅发送一个调度信令，这个调度信令用于向PSCell Group中指定的一个PSCell分配时域资源和频域资源，而向PSCell Group中的其它PSCell分配的时域资源和频域资源基于此按照一定的规律进行偏移。方式二中，虽然仅发送了一个调度信令，但是向PSCell Group中的不同小区分配的时频资源是不相同的。
方式三：
针对PCell Group中的每个PCell分别发送一个调度信令，以分别向PCell Group中的每个PCell分配时域资源和频域资源。
类似地，针对PSCell Group中的每个PSCell分别发送一个调度信令，以分别向PSCell Group中的每个PSCell分配时域资源和频域资源。
4、PCell Group或PSCell Group中的任一小区进行PDCCH或e-PDCCH信道检测的LBT机制主要包括如下两个：
（1）LBT机制1：
若任一小区在子帧n的起始位置进行16μs+M×9μs的one shot的信道检测过程检测到PDCCH或e-PDCCH信道空闲，则在所述子帧n中的剩余时长内发送所述调度信令；或
若任一小区在子帧n之前的子帧的末尾位置进行16μs+M×9μs的one shot的信道检测时检测到PDCCH或e-PDCCH信道空闲，则在子帧n中发送所述调度信令；
其中，M=1或2。
具体地，譬如某一小区在subframe#0内的前端25μs进行信道检测，若检测信道空闲，则在subframe#0接下来的时间发送调度信令。或者某一小区是在subframe#0前面的subframe#9的最后端的25μs进行信道检测，若检测信道空闲，则在subframe#0发送调度信令。
需要注意的是：这个25μs的信道检测时间分为16μs和9μs，25μs信道空闲表示：16μs中的前9μs信道持续空闲；并且9μs中的任意4μs信道持续空闲。
（2）LBT机制2：
在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs之后，从0至竞争窗口之间选取随机数，其中，M为正整数；
在选取所述随机数后继续以9μs为单位进行信道检测，若检测到PDCCH或e-PDCCH信道忙，则所述随机数的值不变，并在检测到PDCCH或e-PDCCH信道持续空闲的时长达到16μs+M×9μs时，所述随机数的值减1；若检测到PDCCH或e-PDCCH信道空闲，则所述随机数的值减1；
在所述随机数的值减为0时，确定能够占用PDCCH或e-PDCCH信道。
5、终端在PCell Group或PSCell Group中的任一小区上进行PUCCH或PRACH信道检测的LBT机制与PDCCH或e-PDCCH的LBT机制相同，不再赘述。
