Description

通信方法与通信装置
本申请要求于2022年8月12日提交中国国家知识产权局、申请号为202210968331.9、申请名称为“通信方法与通信装置”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
本申请涉及通信技术领域，更具体地，涉及一种通信方法与通信装置。
背景技术
在无线通信系统中，终端设备的峰值速率与其所能获得的通信带宽息息相关。在单个小区的通信带宽固定的情况下，可以通过载波聚合技术将多个小区的通信带宽聚合起来，实现终端设备的峰值速率的提升。
在载波聚合的场景中，当为终端设备配置辅载波时，可以同时携带辅载波的载波索引与工作在该辅载波的辅小区的小区标识。在这种情况下，载波与小区是等同的概念。譬如，终端设备接入载波和终端设备接入小区是等同的概念。其中，载波的带宽可以理解为小区的通信带宽。通过将多个载波(也可称为分量载波)聚合起来，终端设备获得的通信带宽是多个分量载波的带宽之和，其峰值速率也能得到提升。
在一个符号上，不同分量载波之间可能存在传输方向不一致的问题。现有的用于解决不同分量载波之间传输方向不一致的方向冲突处理准则适用于分量载波对应的小区均为时分双工系统中传统的时分双工小区的场景，但不适用于分量载波对应的小区中包括时分双工系统中子带全双工小区的场景。

具体来说，当分量载波对应的小区包括SBFD小区时，且SBFD小区包括至少两个子带时，终端设备可以确定SBFD小区的第一子带，并根据第一子带来确定参考小区与第一其他小区中的至少一个小区在第一时间单元上的传输方向。
可选地，参考小区可以是SBFD小区，或者，第一其他小区可以是SBFD小区，或者参考小区与第一其他小区均为SBFD小区。对于参考小区与第一其他小区均为SBFD小区的场景，终端设备需要确定参考小区用于参与方向冲突处理的代表子带(例如，第一子带)，以及，第一其他小区用于参与方向冲突处理的代表子带(例如，第三子带)，并根据各自的代表子带来确定各自在第一时间单元上的传输方向。
结合第一方面，在第一方面的某些实现方式中，第一子带在第一时间单元的传输方向与第二子带在第一时间单元的传输方向冲突。
如此，就可以避免因第一子带与第二子带在时间单元W1的传输方向冲突而得出两个截然不同的冲突判断结果，从而导致错误判断案例的增加，进而能够有效解决分量载波对应的小区中包括子带全 双工小区时，不同分量载波之间存在传输方向不一致的问题。
结合第一方面，在第一方面的某些实现方式中，传输方向包括以下至少一项：信号传输方向，或者，静态配置的符号方向；信号传输方向包括以下至少一项：静态信号传输方向，或者，动态信号传输方向。
具体而言，至少一个其他小区在第一时间单元上可以配置有上述的静态信号传输方向、动态信号传输方向以及静态配置的符号方向中的任意一种，参考小区在第一时间单元上可以配置有上述的静态信号传输方向、动态信号传输方向以及静态配置的符号方向中的任意一种。
结合第一方面，在第一方面的某些实现方式中，参考小区是在第一时间单元配置有静态传输方向的激活服务小区；静态传输方向包括以下至少一项：静态信号传输方向，或者，静态配置的符号方向。
如此，可以避免参考小区的选择随动态信号传输而变化，终端设备可提前确定好第一时间单元上的参考小区，且可避免因动态信号接收失败导致终端设备和小区对于参考小区的理解不一致的问题。
结合第一方面，在第一方面的某些实现方式中，第一子带满足以下至少一项条件：
条件一：第一子带在第一时间单元配置有信号传输方向，第二子带在第一时间单元没有配置信号传输方向，其中，第一子带在第一时间单元的信号传输方向与第二子带在第一时间单元的静态配置的符号方向冲突；
条件二：第一子带在第一时间单元配置有信号传输方向，第二子带在第一时间单元配置有信号传输方向，第一子带在第一时间单元的信号传输方向与子带全双工小区的最终信号传输方向一致，其中，第一子带在第一时间单元的信号传输方向与第二子带在第一时间单元的信号传输方向冲突；
条件三：第一子带在第一时间单元配置有静态配置的符号方向，第二子带在第一时间单元配置有静态配置的符号方向，第一子带的标识小于或者大于第二子带的标识，或者第一子带在第一时间单元的静态配置的符号方向为上行或者下行，其中，第一子带在第一时间单元的静态配置的符号方向与第二子带在第一时间单元的静态配置的符号方向冲突，以及，第一子带在第一时间单元没有信号传输方向的配置，第二子带在第一时间单元没有信号传输方向的配置。
具体来说，终端设备可以根据上述的多项条件的一项或者多项来确定SBFD小区中的多个子带中用于处理参考小区与第一其他小区在第一时间单元上的传输方向冲突的问题的第一子带。如此，就可以避免因第一子带与第二子带在时间单元W1的传输方向冲突而得出两个截然不同的冲突判断结果，从而导致错误判断案例的增加，进而能够有效解决分量载波对应的小区中包括子带全双工小区时，不同分量载波之间存在传输方向不一致的问题。
上述的三项条件可看做是SBFD小区内冲突处理的示意，根据SBFD小区内冲突处理，确定出SBFD小区的传输方向，第一子带和SBFD小区的传输方向相同。具体的SBFD小区内冲突处理以最终的协议为准，本申请发明内容对此不做限定。
另外，上述的SBFD小区的最终信号传输方向可通过如下示例进行确定：
1)第一子带在第一时间单元配置的传输方向为Dynamic-D，第二子带在第一时间单元配置的传输方向为RRC-U，终端设备确定SBFD小区的最终信号传输方向为下行传输方向，终端设备因此选择第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元W1的传输方向。
2)第一子带在第一时间单元配置的传输方向为Dynamic-U，第二子带在第一时间单元配置的传输方向为RRC-D，终端设备确定SBFD小区的最终信号传输方向为上行传输方向，终端设备因此选择第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元W1的传输方向。
上述的两个示例可看做是SBFD小区内冲突处理的示意，根据SBFD小区内冲突处理，确定出SBFD小区的传输方向，第一子带和SBFD小区的传输方向相同。具体的SBFD小区内冲突处理以最终的协议为准，本申请发明内容对此不做限定。
结合第一方面，在第一方面的某些实现方式中，终端设备在第一时间单元确定参考小区与至少一个其他小区之前，该方法还包括：终端设备接收网络设备发送的第一指示信息，该第一指示信息用于指示网络设备为终端设备配置的至少两个激活服务小区，至少两个激活服务小区包括至少一个SBFD小区。
终端设备可以基于网络设备下发的用于指示网络设备为终端设备配置的至少两个激活服务小区的指示信息来确定参考小区与至少一个其他小区，如此，可以避免非激活的服务小区参与后续的方向冲 突处理，减少终端处理的复杂度。
应理解，参考小区与至少一个其他小区均为上述的至少两个激活服务小区中的激活服务小区。
结合第一方面，在第一方面的某些实现方式中，终端设备在第一时间单元确定参考小区与至少一个其他小区，包括：终端设备确定第一小区集合，该第一小区集合中的每个小区是至少两个激活服务小区中配置有静态传输方向的激活服务小区；终端设备确定第一小区为参考小区，该第一小区是该第一小区集合中的任意一个激活服务小区，至少两个激活服务小区中除该第一小区之外的所有小区为至少一个其他小区。
具体来说，终端设备可以从至少两个激活服务小区中筛选出可以作为参考小区的小区集合，且该小区集合中的每个小区都是在第一时间单元配置有静态传输方向的激活服务小区，然后，终端设备可以从该小区集合中选择任意一个小区作为参考小区。如此，就可以避免参考小区的选择随动态信号传输而变化，终端设备可提前确定好第一时间单元上的参考小区，且可避免因动态信号接收失败导致终端设备和小区对于参考小区的理解不一致的问题。
终端设备从该小区集合中确定第一小区为参考小区之后，至少两个激活服务小区中除第一小区之外的所有小区均为其他小区。
应理解，至少两个激活服务小区中的每个激活服务小区在第一时间单元均配置有传输方向的。
结合第一方面，在第一方面的某些实现方式中，第一小区的索引值是第一小区集合中所有小区的索引值中的最小值。
结合第一方面，在第一方面的某些实现方式中，第一小区集合包括的至少一个SBFD小区中的每个SBFD小区在第一时间单元配置有信号传输方向。
具体地，SBFD小区中，多个子带的符号方向配置可以不同，此时，子带的符号方向配置无法表征SBFD小区的传输方向。在SBFD小区中多个子带有静态符号方向配置，其中存在2个子带的静态配置的符号方向配置相反，且多个子带上均无信号传输的情况下，可避免SBFD小区参与方向冲突处理判断，这可以减少终端处理的复杂度。即有信号传输的SBFD小区才会参与方向冲突处理。
结合第一方面，在第一方面的某些实现方式中，终端设备接收网络设备发送的第一指示信息之前，该方法还包括：
终端设备向网络设备发送第二指示信息，该第二指示信息用于指示终端设备是否支持频段间同时收发能力。
如此，可以使能支持频段间收发能力的终端设备在频段内可进行方向冲突处理。
结合第一方面，在第一方面的某些实现方式中，第二指示信息用于指示终端设备支持该频段间同时收发能力时，第一小区集合中的所有小区所属的频段为第一频段；第二指示信息用于指示终端设备不支持该频段间同时收发能力时，第一小区集合中的所有小区所属的频段包括第一频段与第二频段，第二频段不同于第一频段。
结合第一方面，在第一方面的某些实现方式中，第一其他小区是配置有方向冲突处理参数的其他小区，该方向冲突处理参数用于使终端设备确定第一其他小区参与方向冲突处理。
通过上述参数，终端设备可以确定当第一其他小区与参考小区在第一时间单元上的传输方向发生冲突时，终端设备可以处理该传输方向冲突问题。
结合第一方面，在第一方面的某些实现方式中，第一时间单元包括以下至少一项：时隙，符号，或者，微时隙。
具体来说，第一时间单元为时隙(可以是一个时隙，也可以是多个时隙)时，前文所述的传输方向冲突是在时隙上进行冲突判断处理的。第一时间单元为符号(可以是一个符号，也可以是多个符号)时，前文所述的传输方向冲突是在符号上进行冲突判断处理的。第一时间单元为微时隙(mini-slot)(可以是一个微时隙，也可以是多个微时隙)时，前文所述的传输方向冲突是在微时隙上进行冲突判断处理的。

具体地，网络设备110可以通过小区#0、小区#1、小区#2、小区#3等四个小区与终端设备120进行上行/下行通信。其中，小区#0与小区#1位于频段A，小区#2与小区#3位于频段B。
终端设备120通过载波聚合技术将上述的四个小区的载波聚合起来，使其获得更大的通信带宽，继而提升终端设备的上行/下行峰值速率。
应理解，本申请实施例对通信系统100包括的终端设备120与网络设备110的数量不作限定。终端设备120可以是如上所列举的任意一个终端设备，网络设备110也可以是如上所列举的任意一个网络设备。
下文将对与本申请实施例揭示的技术方案相关的部分技术术语作简短的描述。
1.载波聚合。
载波聚合(carrier aggregation，CA)是指将多个分量载波(component carrier，CC)进行聚合处理，从而获得更大通信带宽的载波的技术。
具体来说，根据聚合的多个CC所属的频段及多个CC在频域上是否连续，CA技术可以分为如下几类：
1)频段内连续载波聚合：多个CC同属一个频段，且在频域上连续。
2)频段内非连续载波聚合：多个CC同属一个频段，且在频域上不连续。
3)频段间载波聚合：多个CC分别属于不同的频段。
示例性地，小区#1与小区#2属于频段A，小区#1与小区#2之间的聚合属于第一类CA或者第二类CA。小区#3与小区#4属于频段B，小区#3与小区#4之间的聚合属于第一类CA或者第二类CA。小区#2属于频段A，小区#3属于频段B，小区#2与小区#3之间的聚合属于第三类CA。
在CA的场景中，当为终端设备配置辅载波(secondary cell)时，可以同时携带辅载波的载波索引以及工作在该辅载波的辅小区的小区标识(cell indentify，Cell ID)。在这种情况下，载波与小区是等同的两个概念。譬如，终端设备接入载波和终端设备接入小区是等同的。其中，载波的带宽可以理解为小区的通信带宽。通过将多个CC聚合起来，终端设备获得的通信带宽是多个CC的带宽之和，其峰值速率也能得到提升。
然而，在CA的场景中，在一个时间单元(譬如，符号(symbol)上，不同CC之间可能存在传输方向不一致的问题。此时，不同CC之间的传输方向需要进行方向冲突处理(directional collision  handling)，从而确定每个CC在一个时间单元上的传输方向。具体将在下文进行描述。
2.子带全双工
为了克服TDD系统中的下行链路(downlink，DL)与上行链路(uplink，UL)之间的频域资源分配不平衡的问题(具体来说，就是用于DL传输的频域资源多，用于UL传输的频域资源少)，目前提出一种名为子带全双工(subband fullduplex，SBFD)的技术方案。在该方案中，一个CC可以分为多个子带，且不同子带配置的传输方向可以不同，具体可以参看图2。
图2是子带全双工的示意图。如图2所示，一个CC可以分为三个子带。具体地，在符号#1上，子带#1与子带#3配置的传输方向均为DL传输方向，子带#2配置的传输方向为UL传输方向。在符号#2上，子带#1、子带#2以及子带#3配置的传输方向均为UL传输方向。UL传输方向与DL传输方向可以分别采用不同的频域资源。相比于原有的符号#1的所有频域资源全用于DL传输的方案，SBFD的技术方案能够增加用于UL传输的资源，从而能够有效降低UL传输的时延。
另外，不同的子带能够分别占据不同的频域资源，且不同的子带所占据的频域资源彼此之间互不重叠。例如，子带#1占据的频域资源与子带#2占据的频域资源不同，且没有重叠的频域资源。
此外，在一个符号上，2个子带的符号方向不同时，子带之间可以存在一定的频率保护间隔，用来减少2个子带上传输方向不同的信号之间干扰。例如，在符号#1上，子带#1和子带#2之间可以存在一定的频率保护间隔(guard banding，GB)GB#1，子带#2和子带#3之间可以存在一定的频率保护间隔GB#2，GB#1和GB#2可以为相同值。
3.方向冲突处理准则
正如前文所述，在CA的场景中，在一个时间单元(譬如，符号)上，构成CA的多个CC之间可能存在传输方向不一致的问题。此时，多个CC之间需要进行方向冲突处理，确定每个CC在时间单元上的传输方向。不同CC之间进行的方向冲突处理具体可以参看下文描述。
具体地，若UE满足如下条件：
1)配置了多个激活服务小区(譬如，上述的小区#1、小区#2、小区#3和小区#4)，且在该多个激活服务小区中有一个或多个小区配置了参数directionalCollisionHandling-r16＝'enabled'；
2)支持half-DuplexTDD-CA-SameSCS-r16能力；
3)在任一激活服务小区中未配置监听承载下行控制信息(downlink control information，DCI)2-0的物理下行控制信道(physical downlink control channel，PDCCH)。
UE可以在任意一个时间单元(下文以符号为例进行描述)上选择激活服务小区中小区索引值最小的服务小区作为参考小区(reference cell)。当UE支持频段间同时收发能力(simultaneousRxTxInterBandCA)时，UE能够从每个频段的激活服务小区中选择小区索引值最小的服务小区为参考小区。例如，UE选择频段A上的小区#1作为参考小区，选择频段B上的小区#3作为参考小区。当UE不支持频段间同时收发能力时，UE能够从所有激活服务小区中选择小区索引值最小的服务小区为参考小区。例如，UE选择小区#1～小区#4中的小区#1作为参考小区。
UE支持频段间同时收发能力，其表示：UE支持在频段A进行发送的同时在频段B进行接收，此时，频段A的小区#1和频段B的小区#3是支持同时收发的。UE不支持频段间同时收发能力，其表示：UE不支持在一个频段A进行发送的同时在另一个频段B进行接收。
在激活服务小区中，一个符号上的服务小区需要满足如下至少一项条件才能作为参考小区：
1)静态配置为Semi-D/U(tdd-UL-DL-ConfigurationCommon or tdd-UL-DL-ConfigurationDedicated)
2)符号为flexible，且UE在该符号上配置为发送探测参考信号(sounding reference signal，SRS)、物理上行控制信道(physical uplink control channel，PUCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)或者物理随机接入信道(physical random access channel，PRACH)(可以写为无线资源控制-上行(radio resource control uplink signal，RRC-U))。
3)符号为flexible，且UE在该符号上配置为接收PDCCH，物理下行共享信道(physical downlink shared channel，PDSCH)或者信道状态信息-参考信号(channel state information reference signal，CSI-RS)(可以写为RRC-D)。
简单来说，一个符号上的服务小区要满足如上三项条件之一就可以成为参考小区。上述三项条件可以统称为静态配置的传输方向。另外，静态配置的传输方向也可以理解为静态传输方向。其中，静 态传输方向包括：静态信号传输方向(可以为RRC-D/U)与静态配置的符号方向(可以为Semi-D/U)。
上述的第一项条件也可以称为静态配置的符号方向(包括上行方向与下行方向)，第二项条件和第三项条件可以称为静态信号传输方向(包括上行信号传输方向与下行信号传输方向)。
小区#1作为参考小区后，小区#2～小区#4可以称为小区#1的其他小区(other cell)。小区#1与小区#3分别作为参考小区后，小区#2可以称为小区#1的其他小区，小区#4可以称为小区#3的其他小区。
参考小区确定以后，其他小区的数量可以在至少一个以上。譬如，小区#1为参考小区时，其他小区可以包括小区#2(UE不支持频段间同时收发)，其他小区也可以包括小区#2～小区#4(UE支持频段间同时收发)。
其他小区可以有静态配置的传输方向，也可以没有静态配置的传输方向。换言之，其他小区可能为：符号为flexible，且UE在该符号上由DCI指示发送或接收信号(可写为Dynamic-U/D)。
示例性地，UE在符号#M上选择了参考小区后，可以根据参考小区的Semi-D/U、RRC-D/U以及Dynamic-D/U(参考小区也可以配置动态信号传输方向)和配置了参数directionalCollisionHandling-r16＝'enabled'(该参数可以称为方向冲突处理参数)的其他小区进行方向冲突处理。其他小区在符号#M上可以有Semi-D/U，RRC-D/U以及Dynamic-D/U中的任意一项。
本申请实施例中，其他小区和参考小区之间的方向冲突处理可以理解为：配置了参数directionalCollisionHandling-r16＝'enabled'的其他小区和参考小区在时间单元上的传输方向之间的冲突处理。
其中，参考小区不一定配置了参数directionalCollisionHandling-r16＝'enabled'。还有，参考小区和其他小区在时间单元上(例如，符号#M)的传输方向相同时，则不存在方向冲突处理的问题。在此做统一说明，后文不再赘述。
关于具体的方向冲突处理准则可以参看表1。
表1
表1中，场景1中，参考小区在符号#M的传输方向为Dynamic-D/U，其他小区在符号#M的传输方向为Dynamic-U/D，UE期望避免该情况的发生(error case)。场景2中，参考小区在符号#M的传输方向为Dynamic-D，其他小区在符号#M的传输方向为Semi-U/RRC-U，UE取消在其他小区的发送(drop U on other cell)。场景3中，参考小区在符号#M的传输方向为Dynamic-U，其他小区在符号#M 的传输方向为Semi-D/RRC-D，UE取消在其他小区的接收(drop D on other cell)。场景4中，参考小区在符号#M的传输方向为Semi-U/RRC-U，其他小区在符号#M的传输方向为Dynamic-D，UE期望避免该情况的发生(error case)。场景5-1中，参考小区在符号#M的传输方向为Semi-D/RRC-D，其他小区在符号#M的传输方向为Dynamic-U，若为频带间载波聚合，参考小区在符号#M的传输方向为Semi-D时，UE在其他小区发送(Tx on other cell)；参考小区在符号#M的传输方向为RRC-D时，UE不要求参考小区接收(not required to receive on reference cell)。在场景5-2中，参考小区在符号#M的传输方向为Semi-D/RRC-D，其他小区在符号#M的传输方向为Dynamic-U，若为频带内载波聚合，UE期望避免该情况的发生(error case)。在场景6-1中，参考小区在符号#M的传输方向为Semi-D/U，其他小区在符号#M的传输方向为Semi-U/D，若为频带间载波聚合，则假设其他小区的符号为灵活配置(assume符号#M as Flexible on the other cell)。在场景6-2中，参考小区在符号#M的传输方向为Semi-D/U，其他小区在符号#M的传输方向为Semi-U/D，若为频带内载波聚合，UE期望避免该情况的发生(error case)。在场景7中，参考小区在符号#M的传输方向为Semi-D/U，其他小区为RRC-U/D，UE取消在其他小区的发送或者接收(drop U/D on other cell)。在场景8中，参考小区在符号#M的传输方向为RRC-D/U，其他小区在符号#M的传输方向为Semi-U/D，UE假设其他小区的符号为灵活配置(assume符号#M as Flexible on the other cell)，并取消在其他小区发送RRC-U或者接收RRC-D。在场景9中，参考小区在符号#M的传输方向为RRC-D/U，其他小区在符号#M的传输方向为RRC-U/D，UE取消在其他小区的发送或者接收(drop U/D on other cell)。
但是，表1所示的方向冲突处理准则适用于TDD系统中传统的TDD小区(例如，Legacy TDD小区)。当TDD系统中存在SBFD小区时，上述的方向冲突处理准则就不一定适用了。具体可以参看表2所示的内容。
表2
表2中，对于SBFD小区来说，符号的传输方向配置为子带级别的。因此，一个SBFD小区包括三个子带时，其会包括三个传输方向配置。例如，符号#1上，子带#1的传输方向为Semi-D、子带#2的传输方向为Semi-D、子带#3的传输方向为Semi-D。符号#2上，子带#1的传输方向为RRC-D、子带#2的传输方向为F(灵活可变)、子带#3的传输方向为Semi-D。符号#3上，子带#1的传输方向为RRC-D、子带#2的传输方向为Semi-U、子带#3的传输方向为Dynamic-D。符号#4上，子带#1的传输方向为Semi-D、子带#2的传输方向为Semi-U、子带#3的传输方向为Semi-D。符号#5上，子带#1的传输方向为F、子带#2的传输方向为RRC-U、子带#3的传输方向为F。
对于Legacy TDD小区来说，符号的传输方向配置为小区级别的，其只会有一个传输方向配置。例如，符号#1上，传输方向为RRC-D。符号#2上，传输方向为Semi-D。符号#3上，传输方向为Semi-D/RRC-D。符号#4上，传输方向为Semi-U。符号#5上，传输方向为Semi-U。
对比二者可知，对于SBFD小区而言，符号#3上，子带#3的传输方向为Dynamic-D，子带#2的传输方向为Semi-U，子带#1的传输方向为RRC-D，UE可进行Dynamic-D和RRC-D。对于Legacy TDD小区而言，符号#3上，传输方向为Semi-U，则配置的RRC-D会被取消(drop)，且UE不期望有配置Dynamic-D(上行的优先级高于下行的优先级)。
由于SBFD小区在两个子带上可能存在传输方向不一致的问题，一个Legacy TDD小区需要分别与SBFD小区中的两个子带进行方向冲突处理时，可能会存在一些问题。具体可以参看表3和表4。
表3
表3中，SBFD小区的两个子带的传输方向相反，Legacy TDD小区的传输方向与子带#1的传输方向相同。例如，场景a—c中，参考小区为SBFD小区，其他小区为Legacy TDD小区，子带#1在符号#M的传输方向为Dynamic-D/U或者RC-D/U，子带#2在符号#M的传输方向为Semi-U/D，Legacy TDD小区在符号#M的传输方向为Dynamic-D/U、Semi-D/U或者RRC-D/U，其与子带#1在符号#M的传输方向相同，与子带#2在符号#M的传输方向相反。场景d中，参考小区为Legacy TDD小区，其他小区为SBFD小区，Legacy TDD小区在符号#M的传输方向为Semi-D/U，SBFD小区的子带#1在符号#M的传输方向为Dynamic-D/U或RRC-D/U，子带#2的在符号#M的传输方向为Semi-U/D，子带#1在符号#M的传输方向与Legacy TDD小区在符号#M的传输方向相同，子带#2在符号#M的传输方向与Legacy TDD小区在符号#M的传输方向相反。
表4
表4中，SBFD小区的两个子带的传输方向相反，且Legacy TDD小区的传输方向与子带#1的传输方向相同。例如，场景e—g中，参考小区为SBFD小区，其他小区为Legacy TDD小区，子带#1在符号#M的传输方向为Semi-D/U，子带#2在符号#M的传输方向为Semi-U/D，Legacy TDD小区在符号#M的传输方向分别为Dynamic-D/U、Semi-D/U或者RRC-D/U，其与子带#1在符号#M的传输方向相同， 与子带#2在符号#M的传输方向相反。场景h中，参考小区为Legacy TDD小区，其他小区为SBFD小区，Legacy TDD小区在符号#M的传输方向为Semi-D/U，SBFD小区的子带#1在符号#M的传输方向为Semi-D/U，子带#2在符号#M的传输方向为Semi-U/D，子带#1在符号#M的传输方向与Legacy TDD小区在符号#M的传输方向相同，子带#2在符号#M的传输方向与Legacy TDD小区在符号#M的传输方向相反。
此时，同时对比SBFD小区的两个子带在符号#M的传输方向和Legacy TDD小区在符号#M的传输方向，则会存在如下两个问题：
问题1：
1)Legacy TDD小区在符号#M的传输方向和SBFD小区的子带#1在符号#M的传输方向相同：
a)Legacy TDD小区和SBFD小区的信号均无法传输：Dynamic-D/U信号无法传输(场景a)；
b)Legacy TDD小区的信号无法传输：RRC-D/U信号会被取消接收/发送(场景c)
2)Legacy TDD小区在符号#M的传输方向和SBFD小区的子带#1在符号#M的传输方向相同，但Legacy TDD小区的信号无法传输：RRC-D/U信号会被取消接收/发送(场景g)，Dynamic-D/U信号无法传输(场景e)。
问题2：
1)SBFD小区的子带#2在符号#M的传输方向和子带#1在符号#M的传输方向相反，Legacy TDD小区在符号#M的传输方向和SBFD小区的子带#1在符号#M的传输方向相同，但SBFD小区的子带#1的信号仍无法传输(场景b和场景d)；
2)Legacy TDD小区在符号#M的传输方向为Semi-D或Semi-U，UE均不期望发生这种情况(为error case)(场景f和场景h)。
综上，现有的方向冲突处理准则适用于分量载波对应的小区均为时分双工系统中传统时分双工小区的场景，但不适用于分量载波对应的小区中包括子带全双工小区的场景。
鉴于上述技术问题，本申请提供了一种通信方法与通信装置，能够解决分量载波对应的小区中包括子带全双工小区时，不同分量载波之间存在传输方向不一致的问题。
下文将结合附图对本申请实施例的通信方法与通信装置进行描述。
图3是本申请实施例的通信方法300的交互流程图。图3中的方法流程可以由终端设备120执行，或者由安装于终端设备120中的具有相应功能的模块和/或器件(譬如，芯片或集成电路等)执行，本申请实施例不限定。下文以终端设备120为例进行说明。如图3所示，通信方法300包括：
S310、终端设备120在时间单元W1确定参考小区与至少一个其他小区，参考小区与至少一个其他小区是在时间单元W1配置有传输方向的激活服务小区，参考小区在时间单元W1的传输方向与第一其他小区在时间单元W1的传输方向冲突，第一其他小区是至少一个其他小区中的任意一个其他小区，参考小区与第一其他小区中的至少一个小区是SBFD小区，SBFD小区包括第一子带与第二子带。
具体来说，终端设备120可以确定时间单元W1上的参考小区与至少一个其他小区。参考小区与至少一个其他小区均是在时间单元W1配置有传输方向的激活服务小区。
更具体地说，一个时间单元上可以包括多个激活服务小区。其中，多个激活服务小区中的一个小区可以作为参考小区，除参考小区之外的所有小区可以作为其他小区。
在一个时间单元上(例如，时间单元W1)，参考小区与至少一个其他小区在该时间单元上的传输方向可能存在冲突。为便于描述，本申请实施例仅以参考小区与至少一个其他小区中的第一其他小区在时间单元W1上的传输方向冲突为例进行描述，但不限定参考小区与至少一个其他小区中的第二其他小区在时间单元W1上的传输方向冲突等场景。
一个可能的实现方式，第一其他小区是配置有方向冲突处理参数的其他小区，该方向冲突处理参数用于使终端设备确定第一其他小区可以参与方向冲突处理。例如，终端设备确定第一其他小区在时间单元W1的传输方向与参考小区在时间单元W1的传输方向冲突时，且确定第一其他小区配置有方向冲突处理参数时，能够对第一其他小区与参考小区在时间单元W1的传输方向进行方向冲突处理判断。换言之，终端设备120能够根据该参数确定对第一其他小区与参考小区在时间单元W1上的传输方向进行方向冲突处理。
具体地，第一其他小区是至少一个其他小区中配置方向冲突处理参数的其他小区，该方向冲突处 理参数可以为前述的“directionalCollisionHandling-r16＝'enabled'”参数，该参数能够使得第一其他小区在与参考小区在时间单元W1的传输方向冲突时，终端设备120可以对第一其他小区与参考小区在时间单元W1的传输方向进行方向冲突处理，从而确定第一其他小区与参考小区各自在时间单元W1的传输方向。
可选地，第一其他小区可以是没有配置有方向冲突处理参数的其他小区，终端设备可以直接对第一其他小区与参考小区在时间单元W1的传输方向进行方向冲突处理判断。
为便于描述，本申请实施例以第一其他小区与参考小区在时间单元W1的传输方向冲突为例进行描述，但不限定至少一个其他小区中与参考小区在时间单元W1的传输方向冲突的其他小区的数量，例如，还可以包括第二其他小区、第三其他小区等，其均与参考小区在时间单元W1的传输方向冲突等场景。
参考小区与第一其他小区中至少一个小区是SBFD小区，可以包括以下任意一个：参考小区是SBFD小区，第一其他小区是非SBFD小区，例如，Legacy TDD小区；或者，第一其他小区是SBFD小区，参考小区是非SBFD小区，例如，Legacy TDD小区；又或者，参考小区是第一SBFD小区，第一其他小区是第二SBFD小区。其中，第一SBFD小区包括第一子带与第二子带，第二SBFD小区包括第三子带与第四子带。
应理解，参考小区与第一其他小区中的任意一个小区为SBFD小区时(例如，参考小区为SBFD小区，或者，第一其他小区为SBFD小区)，且参考小区在时间单元W1的传输方向与第一其他小区在时间单元W1的传输方向冲突，以及，SBFD小区包括至少两个子带，以现有的方向冲突处理方式，SBFD小区的每个子带需要和另一个小区进行比较。例如，参考小区为SBFD小区时，SBFD小区的每个子带需要和第一其他小区进行方向冲突处理，则容易导致如表3和表4所示的问题。
为便于描述，本申请实施例以SBFD小区包括第一子带与第二子带为例进行描述，但不限定SBFD小区所包括的子带的数量在两个以上的场景。
参考小区与第一其他小区在时间单元W1的传输方向冲突，可以理解为：参考小区在时间单元W1的传输方向与第一其他小区在时间单元W1的传输方向相反。譬如，参考小区在时间单元W1的传输方向为RRC-D/U，第一其他小区在时间单元W1的传输方向为Dynamic-U/D。
换句话说，参考小区为SBFD小区，第一其他小区为Legacy TDD小区，或者第一其他小区为SBFD小区，参考小区为Legacy TDD小区，参考小区与第一其他小区在时间单元W1的传输方向冲突，可理解为：SBFD小区中的至少一个子带和Legacy TDD小区在时间单元W1上的传输方向相反。参考小区和第一其他小区均为SBFD小区，可以理解为：参考小区中的至少一个子带和第一其他小区中的至少一个子带在时间单元W1上的传输方向相反。例如，第一子带在时间单元W1上的传输方向与第三子带在时间单元W1上的传输方向相反。
正如前文所述，参考小区确定以后，其他小区的数量可以在一个以上。参考小区可以是上述的激活服务小区中索引值最小的一个服务小区，也可以是索引值最大的一个服务小区，也可以是任意一个服务小区等，本申请实施例不限定。另外，关于参考小区的选择可以见后文描述，在此不再多言。
S320、终端设备120根据第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元W1的传输方向。
具体来说，由于SBFD小区包括第一子带与第二子带，第一子带与第二子带各自在时间单元W1上的传输方向可能一致，可能冲突。当第一子带与第二子带各自在时间单元W1上的传输方向一致时，以现有的方向冲突处理方式，第一子带与第二子带需要分别与另一个小区在时间单元W1上进行传输方向冲突判断，则容易导致多余的冲突判断。当第一子带与第二子带各自在时间单元W1上的传输方向冲突时，以现有的方向冲突处理方式，第一子带与第二子带需要分别与另一个小区在时间单元W1上进行传输方向冲突判断，则很容易导致错误的冲突判断。例如，如表3所示的场景a—d，以及，如表4所示的场景e—h。
综上，终端设备120可以根据SBFD小区的第一子带(第一子带可以为SBFD小区的任意子带)确定参考小区在时间单元W1的传输方向与第一其他小区在时间单元W1的传输方向，这样就可以避免上述情况的发生。
具体地，终端设备120根据第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元 W1的传输方向，可以包括如下任意一项情况：
情况#1：终端设备120根据第一子带确定参考小区在时间单元W1的传输方向；
情况#2：终端设备120根据第一子带确定第一其他小区在时间单元W1的传输方向；
情况#3：终端设备120根据第一子带确定参考小区与第一其他小区在时间单元W1的传输方向。
对于情况#1，参考小区为SBFD小区时，第一子带可以为SBFD小区在时间单元W1的传输方向，之后，终端设备120可以取消第一其他小区在时间单元W1的传输方向(可以理解为第一其他小区在时间单元W1的传输方向为无)。
对于情况#2，第一其他小区为SBFD小区，第一子带可以为第一其他小区在时间单元W1的传输方向。可选地，终端设备120可以取消参考小区在时间单元W1的传输方向(可以理解为参考小区在时间单元W1的传输方向为无)。
对于情况#3，示例性地，参考小区为SBFD小区，则参考小区在时间单元W1的传输方向确定了，以及，终端设备120可以取消第一其他小区在时间单元W1的传输方向，如此，第一其他小区在时间单元W1的传输方向也确定了。
当参考小区为第一SBFD小区，第一SBFD小区包括第一子带与第二子带，第一其他小区为第二SBFD小区，第二SBFD小区包括第三子带与第四子带，终端设备120可以先确定第一SBFD小区的第一子带，以及，确定第二SBFD小区的第三子带，并根据第一子带与第三子带来确定参考小区与第一其他小区中的至少一个小区在时间单元W1的传输方向。譬如，终端设备120可以保持参考小区在时间单元W1的传输方向，且取消第一其他小区在时间单元W1的传输方向，或者，终端设备120可以保持第一其他小区在时间单元W1的传输方向，且取消参考小区在时间单元W1的传输方向。
通过上述技术方案，本申请能够解决分量载波对应的小区中包括子带全双工小区时，不同分量载波之间存在传输方向不一致的问题。
具体来说，当分量载波对应的小区包括SBFD小区时，SBFD小区包括至少两个子带时，终端设备可以确定SBFD小区的第一子带，并根据第一子带来确定参考小区与其他小区在时间单元上的传输方向。
一个可能的实现方式，第一子带在时间单元W1的传输方向与第二子带在时间单元W1的传输方向冲突。
具体来说，第一子带与第二子带在时间单元W1的传输方向冲突时，本申请通过选择第一子带与第二子带中的第一子带来确定参考小区和第一其他小区在时间单元W1的传输方向，这可以避免因第一子带与第二子带在时间单元W1的传输方向冲突而得出两个截然不同的冲突判断结果，从而导致错误判断案例的增加，进而能够有效解决分量载波对应的小区中包括子带全双工小区时，不同分量载波之间存在传输方向不一致的问题。
一个可能的实现方式，传输方向可以包括以下至少一项：
信号传输方向，或者，静态配置的符号方向。
具体地，信号传输方向可以包括动态信号传输方向与静态信号传输方向。譬如，动态信号传输方向可以为Dynamic D/U；静态信号传输方向可以为RRC-D/U。静态配置的符号方向可以为Semi-D/U。
具体而言，至少一个其他小区在时间单元W1上可以配置有上述的静态信号传输方向、动态信号传输方向以及静态配置的符号方向中的任意一种，参考小区在时间单元W1上可以配置有上述的静态信号传输方向、动态信号传输方向以及静态配置的符号方向中的任意一种。
一个可能的实现方式，参考小区是在时间单元W1配置有静态传输方向的激活服务小区。
具体来说，参考小区在时间单元W可以配置有RRC-D/U、Semi-D/U中的一项或者多项。譬如，参考小区在时间单元W1配置有RRC-D/U；或者，参考小区在时间单元W1配置有Semi-D/U；或者，参考小区在时间单元W1配置有RRC-D/U与Semi-D/U等。
如此，可以避免参考小区的选择随动态信号传输而变化，终端设备可提前确定好时间单元W1上的参考小区，且可避免因动态信号接收失败导致终端设备和小区对于参考小区的理解不一致的问题。
综上，上述的RRC-D/U以及Semi-D/U可以属于静态传输方向的其中一种情况。
如前文所述，至少一个其他小区是在时间单元W1配置有传输方向的激活服务小区，其可以包括以下至少一项：至少一个其他小区在时间单元W1配置有RRC-D/U、Dynamic-D/U，Semi-D/U中的一 项或者多项等，本申请实施例不做限定。
可选地，参考小区是在时间单元W1配置有传输方向的激活服务小区，也可以包括：参考小区在时间单元W1配置有Dynamic-D/U。
一个可能的实现方式，第一子带满足以下至少一项条件：
a)第一子带在时间单元W1配置有信号传输方向，第二子带在时间单元W1没有配置信号传输方向，其中，第一子带在时间单元W1的信号传输方向与第二子带在时间单元W1的静态配置的符号方向冲突；
b)第一子带在时间单元W1配置有信号传输方向，第二子带在时间单元W1配置有信号传输方向，第一子带在时间单元W1的信号传输方向与SBFD小区的最终信号传输方向一致，其中，第一子带在时间单元W1的信号传输方向与第二子带在时间单元W1的信号传输方向冲突；
c)第一子带在时间单元W1配置有静态配置的符号方向，第二子带在时间单元W1配置有静态配置的符号方向，第一子带在时间单元W1没有信号传输方向的配置，第二子带在时间单元W1没有信号传输方向的配置，第一子带的标识小于或者大于第二子带的标识，或者，第一子带在时间单元W1的静态配置的符号方向为上行或者下行，其中，第一子带在时间单元W1的静态配置的符号方向与第二子带在时间单元W1的静态配置的符号方向冲突。
对于条件a，譬如，第一子带在时间单元W1的信号传输方向为Dynamic-D/U，第二子带在时间单元W1的静态配置的符号方向为Semi-U/D。对于条件b，譬如，第一子带在时间单元W1的信号传输方向为Dynamic-D/U，第二子带在时间单元W1的信号传输方向为RRC-U/D。对于条件c，譬如，第一子带在时间单元W1的静态配置的符号方向为Semi-D/U，第二子带在时间单元W1的静态配置的符号方向为Semi-U/D。具体可以参看表5。
另外，对于条件c，第一子带的标识(ID)可以小于或者大于第二子带的标识。
可选地，第一子带在时间单元W1的传输方向为上行方向或者下行方向，且第二子带在时间单元W1的传输方向为下行方向或者上行方向，则终端设备可以选择第一子带来确定参考小区与第一其他小区中的至少一个小区在时间单元W1的传输方向。
换句话说，第一子带在时间单元W1配置有静态配置的符号方向，第二子带在时间单元W1配置有静态配置的符号方向，第一子带在时间单元W1没有信号传输方向的配置，第二子带在时间单元W1没有信号传输方向的配置，第一子带的标识小于或者大于第二子带的标识，或者，第一子带在时间单元W1的静态配置的符号方向为上行或者下行，其中，第一子带在时间单元W1的静态配置的符号方向与第二子带在时间单元W1的静态配置的符号方向冲突。
表5
表5中，场景#1中，第一子带在时间单元W1的传输方向为Dynamic-D/U，第二子带在时间单元W1的传输方向为Semi-U/D。场景#2中，第一子带在时间单元W1的传输方向为RRC-D/U，第二子带在时间单元W1的传输方向为Semi-U/D。场景#3中，第一子带在时间单元W1的传输方向为Dynamic-D/U，第二子带在时间单元W1的传输方向为RRC-U/D。场景#4中，第一子带在时间单元W1的传输方向为RRC-D/U，第二子带在时间单元W1的传输方向为Dynamic-U/D。场景#5中，第一子带在时间单元W1的传输方向为Semi-D/U，第二子带在时间单元W1的传输方向为Semi-U/D。场景#6中，第一子带在时间单元W1的信号传输方向为同步信号块与物理广播信号块(synchronization  signal block and physical broadcast signal block，SSB)，第二子带在时间单元W1的传输方向为RRC-U/Dynamic-U。应理解，前述的场景1至5中的RRC-D可以没有包括SSB。
应理解，上述的SBFD小区的最终信号传输方向可以通过如下示例进行判断：
(a)第一子带在时间单元W1配置的传输方向为Dynamic-D，第二子带在时间单元W1配置的传输方向为RRC-U，终端设备确定SBFD小区的最终信号传输方向为下行传输方向，终端设备因此选择第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元W1配置的传输方向。
(b)第一子带在时间单元W1配置的传输方向为Dynamic-U，第二子带在时间单元W1配置的传输方向为RRC-D，终端设备确定SBFD小区的最终信号传输方向为上行传输方向，终端设备因此选择第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元W1的传输方向。
(c)第一子带在时间单元W1配置的传输方向为SSB，第二子带在时间单元W1配置的传输方向为RRC-U/Dynamic-U，终端设备确定SBFD小区的最终信号传输方向为下行传输方向，终端设备因此选择第一子带确定参考小区与第一其他小区中的至少一个小区在时间单元W1配置的传输方向。
上述的(a)(b)和(c)是SBFD小区内冲突处理的示意。具体的SBFD小区内冲突处理以最终的协议为准，本申请实施例对此不做限定。
一个可能的实现方式，上述所列举的多个场景之间可以彼此结合起来。譬如，第二子带在时间单元W1的传输方向为RRC-D与Semi-D，第一子带在时间单元W1的传输方向为Dynamic-U与Semi-U，终端设备120可以选择第一子带来确定参考小区与第一其他小区在时间单元W1的传输方向。
如此，就可以避免因第一子带与第二子带在时间单元W1的传输方向冲突而得出两个截然不同的冲突判断结果，从而导致错误判断案例的增加，进而能够有效解决当参考小区和第一其他小区中的一个或者两个均为SBFD小区时的传输方向冲突判断的问题。
可选地，终端设备120可以不选择第一子带或者第二子带的静态配置的符号方向来确定参考小区与第一其他小区在时间单元W1的传输方向。
一个可能的实现方式，终端设备120可以根据上述的三项条件之一来确定第一子带。
当SBFD小区满足如表5所示的任一种场景时，终端设备120可以根据第一子带来确定参考小区与第一其他小区在时间单元W1的传输方向。
一个可能的实现方式，第一子带在时间单元W1的信号传输方向与第二子带在时间单元W1的信号传输方向冲突时，终端设备120可以先确定SBFD小区的最终信号传输方向，继而将与SBFD小区的最终信号传输方向一致的子带与第一其他小区进行方向冲突处理。
譬如，第一子带在时间单元W1的信号传输方向为RRC-D，第二子带在时间单元W1的信号传输方向为Dynamic-U，终端设备120确定SBFD小区的最终信号传输方向为Dynamic-U，则将在时间单元W1的传输方向为Dynamic-U的第一子带与另外一个小区进行传输方向冲突处理。
一个可能的实现方式，第一子带在时间单元W1的传输方向为静态配置的符号方向，第二子带在时间单元W1的传输方向为静态配置的符号方向时，在第一子带和第二子带均无信号传输时，该SBFD小区可以不作为参考小区或者其他小区。如此，也能够避免表4所列举的四种场景的出现。
可选地，第一子带在时间单元W1的传输方向为静态配置的符号方向与信号传输方向，第二子带在时间单元W1的传输方向为静态配置的符号方向，且无信号传输方向，且第一第一子带在时间单元W1的传输方向为静态配置的符号方向与第二子带在时间单元W1的传输方向为静态配置的符号方向冲突，则SBFD小区可以为参考小区或者其他小区，但是SBFD小区仅在有信号传输的方向的子带进行方向冲突处理。
上述的终端设备120以第一子带来确定参考小区与第一其他小区在时间单元W1的传输方向仅作为示例性描述，意在描述当SBFD小区的任意两个子带在时间单元W1的传输方向冲突时(也可以包括一致的场景)，终端设备120可以根据SBFD小区的子带之一来确定参考小区与第一其他小区在时间单元W1的传输方向。
一个可能的实现方式，第一子带在时间单元W1的传输方向与第二子带在时间单元W1的传输方向一致时，终端设备120也可以根据第一子带来确定参考小区与第一其他小区在时间单元W1的传输方向。
一个可能的实现方式，时间单元W1可以包括以下至少一项：
时隙、符号或者微时隙。
具体来说，时间单元W1为时隙时，前文所述的传输方向冲突是在时隙(可以是一个时隙，也可以是多个时隙)上进行冲突判断处理的。时间单元W1为符号时，前文所述的传输方向冲突是在符号(可以是一个符号，也可以是多个符号)上进行冲突判断处理的。时间单元W1为微时隙(mini-slot)时，前文所述的传输方向冲突是在微时隙(可以是一个微时隙，也可以是多个微时隙)上进行冲突判断处理的。
通过上述技术方案，本申请能够解决当不同分量载波对应的服务小区中包括SBFD小区时如何解决参考小区与第一其他小区在时间单元的传输方向冲突时的问题。
具体来说，在表3与表4所示的场景中，当选择SBFD小区的子带之一进行传输方向冲突判断处理时，便能够减少错误或者信号被取消的判定场景的出现。
一个可能的实现方式，可以对SBFD小区配置以下至少一项约束：
1)第一子带在时间单元W1的静态配置的符号方向(Semi-D/U)与第二子带在时间单元W1的信号传输方向(RRC-D/U，Dynamic-D/U)一致；
2)第一子带在时间单元W1的静态配置的符号方向(Semi-D/U)与第二子带在时间单元W1的静态配置的符号方向(Semi-D/U)一致；
3)第一子带在时间单元W1的静态配置的符号类别为Semi-F，第二子带在时间单元W1的静态配置的符号类别为Semi-F。
如此，也能够解决如表3和表4中所列举的8种场景。
可选地，SBFD小区中仅有信号传输方向配置的子带参与方向冲突处理。如此，也可以解决如表3和表4中所列举的8种场景。
一个可能的实现方式，终端设备120在时间单元W1确定参考小区与至少一个其他小区之前，终端设备120可以接收网络设备发送的第一指示信息，第一指示信息用于指示网络设备110为终端设备120配置的至少两个激活服务小区，至少两个激活服务小区包括至少一个SBFD小区。如下参考小区和至少一个其他小区的确定是指时间单元W1上的参考小区和至少一个其他小区的确定。
如此，终端设备120可以根据网络设备110发送的第一指示信息确定至少两个激活服务小区中的参考小区与至少一个其他小区。
具体来说，终端设备120可以根据第一指示信息确定上述的至少两个激活服务小区，至少两个激活服务小区中在时间单元W1配置有静态传输方向的激活服务小区可以组成第一小区集合。终端设备120确定第一小区集合中的第一小区为参考小区，此外，至少两个激活服务小区中除第一小区之外的剩余小区均为其他小区。第一小区可以是第一小区集合中的任意一个激活服务小区。
具体来说，终端设备可以从至少两个激活服务小区中筛选出可以作为参考小区的小区集合，且该小区集合中的每个小区都是在第一时间单元配置有静态传输方向的激活服务小区，然后，终端设备可以从该小区集合中选择任意一个小区作为参考小区。如此，就可以避免参考小区的选择随动态信号传输而变化，终端设备可提前确定好第一时间单元上的参考小区，且可避免因动态信号接收失败导致终端设备和小区对于参考小区的理解不一致的问题。
终端设备从该小区集合中确定第一小区为参考小区之后，至少两个激活服务小区中除第一小区之外的所有小区均为其他小区。
应理解，至少两个激活服务小区中的每个激活服务小区在第一时间单元均配置有传输方向的。
可选地，第一小区的索引值是第一小区集合中的所有小区的索引值中的最小值。
可选地，SBFD小区为参考小区时，网络设备110可以来保证第一其他小区在时间单元W1的传输方向与参考小区在时间单元W1的传输方向不会冲突。
可选地，至少两个激活服务小区中的至少一个SBFD小区属于第一小区集合时，至少一个SBFD小区中的每个SBFD小区可以在时间单元W1上配置有信号传输方向。例如，静态信号传输方向。
具体地，SBFD小区中，多个子带的符号方向配置可以不同，此时，子带的符号方向配置无法表征SBFD小区的传输方向。在SBFD小区中多个子带有静态符号方向配置，其中存在2个子带的静态配置的符号方向配置相反，且多个子带上均无信号传输的情况下，可避免SBFD小区参与方向冲突处理判断，这可以减少终端处理的复杂度。即有信号传输的SBFD小区才会参与方向冲突处理。
一个可能的实现方式，第一子带的索引值小于第二子带的索引值。例如，第一子带的索引值是SBFD小区中所有子带的索引值中的最小值。
一个可能的实现方式，终端设备120可以先向网络设备110发送第二指示信息，该第二指示信息用于指示终端设备120是否支持频段间同时收发能力。
具体地，若第二指示信息用于指示终端设备120支持频段间同时收发能力时，第一小区集合中所有小区所属的频段均相同，例如，均为第一频段。若第二指示信息用于指示终端设备120不支持频段间同时收发能力时，第一小区集合中所有小区所属的频段并不相同，例如，部分小区所属的频段为第一频段，部分小区所属的频段为第二频段，等等。
综上，若第二指示信息用于指示终端设备120不支持频段间同时收发能力时，第一小区集合中所有小区所属的频段包括第一频段与第二频段，且第二频段不同于第一频段。
一个可能的实现方式，网络设备110为终端设备120配置多个服务小区。
具体地，终端设备120可以进行小区接入。终端设备120进行初始接入的小区为主小区(primary cell，PCell)。
具体地，网络设备120可以通过人工配置建立CA频点集合，该CA频点集合包括多个频点。这些频点对应的小区为候选小区(secondary cell，SCell)。网络设备110可以根据候选小区与终端设备120的能力确定终端设备需要添加的候选小区，并通过RRC重配消息将这些候选小区的相关信息发送给终端设备120。终端设备120可以根据候选小区的相关信息去添加相应的候选小区。终端设备120在具体添加时有两种配置候选小区的方式：盲配置和基于测量的配置。
采用盲配置时，终端设备120直接根据网络设备110下发的候选小区相关信息配置候选小区。采用基于测量的配置时，终端设备120需要考虑小区的信号质量，只有当小区的信号质量满足一定条件时，该小区才可以配置为候选小区。
终端设备120在添加候选小区时，在通过无线资源控制配置(radio resource control reconfiguration，RRCReconfiguration)信息进行配置时，RRC信令中可以包含高层配置CellGroupConfig IE，CellGroupConfig IE包括sCell集合(sCellToAddModList)，sCell集合中的每个sCell通过SCellConfig配置。SCellConfig的配置包括sCellState-r16ENUMERATED{activated}，sCellState-r16配置时，候选小区在配置为激活的服务小区。在初次配置候选小区之后，终端设备120或者网络设备110后续可通过MAC CE来激活/去激活候选小区。
此外，网络设备110能够决定候选小区成为激活态的时间。网络设备110可以根据终端设备120的业务量决定是否激活候选小区。当终端设备120等待传输的业务量较大，网络设备110激活候选小区。其中，终端设备120接入的主小区可以一直处于激活态。
一个可能的实现方式，SBFD小区可以不作为参考小区，且仅作为其他小区。如此，也可以解决上述的冲突问题。
一个可能的实现方式，SBFD小区不可配置directionalCollisionHandling-r16＝'enabled'，即CA中不可和SBFD小区同时收发的小区，需由网络设备110保证不会出现方向冲突。如此，也可以解决上述的冲突问题。
图3所示的通信方法的执行主体也可以是网络设备110，网络设备110所执行的步骤与终端设备120所执行的步骤基本一致，具体可以参看上述内容，不再赘述。
一个可能的实现方式，终端设备120向网络设备110发送第二指示信息之前，网络设备110可以向终端设备120发送终端设备能力请求信息(例如，终端设备能力查询信令)，能力请求信息用于请求询问终端设备120的能力。
相应地，终端设备120可以向网络设备110发送终端设备能力反馈信息(例如，终端设备能力信令)，终端设备能力反馈信息用于向网络设备110反馈终端设备120的能力。
具体地，终端设备能力反馈信息可以包括终端设备120的CA能力，还可以包括终端设备120支持的频段组合、是否支持频段间同时收发的能力等信息。
一个可能的实现方式，网络设备110可以根据终端设备120反馈的终端设备能力为终端设备120配置多个服务小区。
具体地，网络设备110可以根据终端设备120上报的能力，为终端设备120配置多个服务小区， 且该多个服务小区可以分布于终端设备120所支持的频段组合之上。
一个可能的实现方式，网络设备110还可以为终端设备120激活网络设备110为终端设备120配置的一个或者多个服务小区。
相应地，终端设备120可以从激活的服务小区中确定参考小区与至少一个其他小区。
下文将结合附图对本申请实施例的其他的通信方法进行描述。
图4是本申请实施例的通信方法400的交互流程图。图4中的方法流程可以由终端设备120执行，或者由安装于终端设备120中的具有相应功能的模块和/或器件(譬如，芯片或集成电路等)执行，本申请实施例不限定。下文以终端设备120为例进行说明。如图4所示，通信方法400包括：
S410、终端设备120在时间单元W2确定参考子带与至少一个其他子带，参考子带与至少一个其他子带是在时间单元W2配置有传输方向的子带，参考子带在时间单元W2的传输方向与第一其他子带在时间单元W2的传输方向冲突。
具体来说，终端设备120可以确定时间单元W2上的参考子带(reference sub-band)与至少一个其他子带(other sub-band)。参考子带与至少一个其他子带是在时间单元W2上配置有传输方向的子带。
更具体地说，一个时间单元上可以包括多个子带。其中，多个子带中的一个子带可以作为参考子带，除参考子带之外的所有子带可以作为其他子带。
在一个时间单元上(例如，时间单元W2)，参考子带与至少一个其他子带在该时间单元上的传输方向可能存在冲突。为便于描述，本申请实施例仅以参考子带与至少一个其他子带中的第一其他子带在时间单元W2上的传输方向冲突为例进行描述，但不限定参考子带与至少一个其他子带中的第二其他子带在时间单元W2上的传输方向冲突等场景。
一个可能的实现方式，第一其他子带是配置有方向冲突参数的其他子带，该方向冲突处理参数用于使终端设备确定第一其他子带可以参与方向冲突处理。例如，终端设备确定第一其他子带在时间单元W2的传输方向与参考子带在时间单元W2的传输方向冲突时，且确定第一其他子带配置有方向冲突处理参数时，则能够对第一其他子带与参考子带在时间单元W2的传输方向进行方向冲突处理判断。换言之，终端设备能够根据该参数确定对第一其他子带与参考子带在时间单元W2上的传输方向进行方向冲突处理。
可选地，第一其他子带可以是没有配置有方向冲突处理参数的其他子带，终端设备可以直接对第一其他子带与参考子带在时间单元W2的传输方向进行方向冲突处理判断。
一个可能的实现方式，参考子带与至少一个其他子带属于SBFD小区；或者，参考子带属于SBFD小区，至少一个其他子带属于Legacy TDD小区；或者，参考子带属于Legacy TDD小区，至少一个其他子带属于SBFD小区，本申请实施例不限定。
S420、终端设备120根据参考子带确定参考子带与第一其他子带中的至少一个子带在时间单元W2的传输方向。
具体来说，参考子带在时间单元W2的传输方向与第一其他子带在时间单元W2的传输方向是冲突的，终端设备可以根据参考子带在时间单元W2的传输方向来处理参考子带与第一其他子带各自在时间单元W2的传输方向。其中，关于传输方向的描述可以参见上文，在此不再赘述。
示例性地，参考子带在时间单元W2的信号传输方向与第一其他子带在时间单元W2的静态配置的符号方向或者静态信号传输方向冲突，终端设备120可以取消第一其他子带在时间单元W2的静态配置的符号方向或者静态信号传输方向。
又示例性地，参考子带在时间单元W2的静态配置的符号方向与第一其他子带在时间单元W2的传输方向冲突，终端设备120可以取消第一其他子带在时间单元W2的传输方向。
关于上述的两项示例性描述可以参看表6。
表6

在表6中，场景s1中，参考子带在符号#M的传输方向为Dynamic-D/U，其他子带在符号#M的传输方向为Dynamic-U/D，终端设备120期望避免该情况的发生(error case)。场景s2中，参考小区在符号#M的传输方向为Dynamic-D，其他子带在符号#M的传输方向为Semi-U/RRC-U，终端设备120取消在其他子带的发送(drop U on other sub-band)。场景s3中，参考子带在符号#M的传输方向为Dynamic-U，其他小区在符号#M的传输方向为Semi-D/RRC-D，终端设备120取消在其他子带的接收(drop D on other sub-band)。场景s4中，参考子带在符号#M的传输方向为Semi-D/U，其他小区在符号#M的传输方向为RRC-U/D，终端设备120取消在其他子带的发送/接收(drop U/D on other sub-band)。场景s5中，参考子带在符号#M的传输方向为RRC-D/U，其他子带在符号#M的传输方向为Semi-U/D，终端设备120取消在其他子带的发送/接收(drop U/D on other sub-band)。在场景s6中，参考子带在符号#M的传输方向为RRC-D/U，其他子带在符号#M的传输方向为RRC-U/D，终端设备120取消在其他子带的发送/接收(drop U/D on other sub-band)。
通过上述技术方案，本申请能够解决当参考子带与其他子带在同一个时间单元上存在传输方向冲突时如何处理的问题。
一个可能的实现方式，参考子带与第一其他子带均属于SBFD小区时，终端设备120根据参考子带确定参考子带与第一其他子带在时间单元W2的传输方向时，可以按照如表7所示的规则进行方向冲突处理。具体可以见表7。
表7
在表7中，场景S1中，参考子带在时间单元W2的传输方向为Semi-D/U，其他子带(第一其他子带)在时间单元W2的传输方向为Dynamic-U/D，终端设备120取消在其他子带(第一其他子带)的发送/接收(drop U/D on other sub-band)。场景S2中，参考子带在时间单元W2的传输方向为Semi-D/U，其他子带(第一其他子带)在时间单元W2的传输方向为Semi-U/D，终端设备120取消在其他子带的发送/接收(drop U/D on other sub-band)。场景S3中，参考子带在时间单元W2的传输方向为Semi-D/U，其他子带(第一其他子带)在时间单元W2的传输方向为RRC-U/D，终端设备120取消在其他子带的发送/接收(drop U/D on other sub-band)。场景S4中，参考子带在时间单元W2的传输方向为Semi-D/U，其他子带(第一其他子带)在时间单元W2的传输方向为Dynamic-U/D，终端设备120取消在参考子带的接收/发送(drop D/U on reference sub-band)。场景S5中，参考子带在时间单元W2的传输方向为RRC-D/U，其他子带(第一其他子带)在时间单元W2的传输方向为RRC-U/D，终端设备120取消在其他子带的发送/接收(drop U/D on other sub-band)。
可选地，参考子带的索引值是SBFD小区或者Legacy TDD小区中所有子带的索引值中的最小值。
可选地，参考子带的索引值是有传输方向配置的子带集合中所有子带的索引值中的最小值。
具体而言，参考子带的索引值是有静态传输方向配置的子带集合中所有子带的索引值中的最小值。 其他子带为至少两个激活的服务小区中除去参考子带外的子带。
可选地，当SBFD小区中的任意一个子带在时间单元W2的传输方向为动态信号传输方向时，剩余子带在该时间单元W2的传输方向需要与动态信号传输方向保持一致，否则可以取消剩余子带在时间单元W2的传输方向。
一个可能的实现方式，终端设备120在时间单元W2确定参考子带与至少一个其他子带之前，终端设备120可以接收网络设备110发送的第三指示信息，第三指示信息用于指示网络设备110为终端设备120配置的至少两个激活服务小区，且至少两个激活服务小区包括至少一个SBFD小区。
如此，终端设备120可以根据网络设备110发送的第三指示信息确定至少两个激活服务小区中的参考子带与至少一个其他子带。
具体来说，终端设备120可以根据第三指示信息确定上述的至少两个激活服务小区，并从上述的至少两个激活服务小区中确定第一子带集合，第一子带集合中的每个子带均是上述的至少两个激活服务小区中配置有静态传输方向的子带。终端设备120可以确定第一子带集合中的第一子带为参考子带，子带集合(上述至少两个激活服务小区包含的子带)中除第一子带之外的剩余子带均为其他子带。其中，第一子带可以是第一子带集合中的任意一个子带。
可选的，第一子带集合中属于SBFD小区的子带配置有静态信号传输方向。
可选地，第一子带的索引值是第一子带集合中所有子带的索引值中的最小值。
可选地，参考子带与第一其他子带均属于SBFD小区时，网络设备110可以来保证第一其他子带在时间单元W2的传输方向与参考子带在时间单元W2的传输方向不会冲突。
按照前述方案可以选出参考小区：
方式1：可选的，参考小区为SBFD小区时，参考子带的索引值是SBFD小区中所有子带的索引值中的最小值；
方式2：可选的，参考小区为SBFD小区时，SBFD小区的传输方向按照SBFD小区内的冲突处理准则得到，参考子带的索引值是SBFD小区中和SBFD小区的传输方向相同的子带中索引值中的最小值；
方式3：可选的，参考小区为legacy TDD小区时，参考子带即为legacy TDD小区对应的子带；
可选的，按照方式2确定参考子带时，一个可能的实现方式，参考子带与第一其他子带均属于SBFD小区时，参考子带与第一其他子带按照SBFD小区内的冲突处理准则进行冲突处理。具体的SBFD小区内冲突处理以最终的协议为准，本申请实施例对此不做限定。
一个可能的实现方式，终端设备120可以先向网络设备110发送第四指示信息，该第四指示信息用于指示终端设备120是否支持频段间同时收发能力。
具体地，若第四指示信息用于指示终端设备120支持频段间同时收发能力时，该子带集合中所有子带所属的频段均相同，例如，均为第三频段。若第四指示信息用于指示终端设备120不支持频段间同时收发能力时，该子带集合中所有子带所属的频段并不相同，例如，部分子带所属的频段为第三频段，部分子带所属的频段为第四频段，等等。
综上，若第四指示信息用于指示终端设备120不支持频段间同时收发能力时，该子带集合中所有子带所属的频段包括第三频段与第四频段，且第四频段不同于第三频段。
图4所示的通信方法的执行主体也可以是网络设备110，网络设备110所执行的步骤与终端设备120所执行的步骤基本一致，具体可以参看上述内容，不再赘述。
