具体实施方式
以下结合附图对本公开实施例进行说明，以下说明的实施例仅用于说明和解释本公开，并不用于限定本公开。
在TDD LTE系统实际应用时，多个上行符号上的干扰可能存在差异，例如，大气波导(Atmosphere Duct)下，上行符号上的干扰从UpPTS起依次减小。再例如，当由于某种原因出现交叉时隙干扰时，多个上行符号上的干扰也是存在差异的。同样地，在5G通信系统中，也存在符号间干扰差异导致上行整体性能损失的问题。
本公开提供一种通信方法及装置，引入用于上行传输的符号自适应机制，以减少干扰对上行传输带来的影响。
图2为本公开实施例提供的一种通信方法的流程图。如图2所示，本实施例提供的通信方法包括：
步骤201、基站发送符号配置信息。
其中，符号配置信息用于指示以下至少之一：不能用于上行传输的上行符号以及可用于上行传输的上行符号。
在示例性实施方式中，符号配置信息可以由小区级广播消息和UE级授权信息中至少之一携带。然而，本公开对此并不限定。在其他实现方式中，符号配置信息还可以由其他消息携带。
在示例性实施方式中，小区级广播消息携带的符号配置信息可以用于向小区内所有UE指示哪些上行符号可用于上行传输或者哪些上行符号不能用于上行传输；UE级授权信息携带的符号配置信息可以用于向该UE指示哪些上行符号可用于上行传输或者哪些上行符号不能用于上行传输。
在示例性实施方式中，符号配置信息可以由以下至少之一携带：系统消息块(System Information Block，SIB)1、移动控制信息中的无线资源配置公共消息(MobilityControlInfo→RadioResourceConfigCommon)、下行控制信息(Downlink Control Information，DCI)。
在示例性实施方式中，在步骤201之前，本实施例的通信方法还可以包括：
步骤100、基站对预设类型的干扰进行检测。
在示例性实施方式中，基站可以打开大气波导检测功能，进行大气波导相关的干扰检测，或者基站可以进行上行交叉时隙的干扰检测。
步骤200、基站根据干扰检测结果，确定符号配置信息。
在示例性实施方式中，基站可以根据大气波导干扰的检测结果，或者，可以根据上行交叉时隙干扰的检测结果，确定可用于上行传输的上行符号或者不能用于上行传输的上行符号，然后，根据确定的信息，设置符号配置信息。然而，本公开对此并不限定。在其他实现方式中，基站还可以采用其他检测方式确定可用于上行传输的上行符号或不能用于上行传输的上行符号。
在示例性实施方式中，符号配置信息可以包括：一个周期内每个上行符号对应的比特域取值，其中，可用于上行传输的上行符号对应的比特域取值与不能用于上行传输的上行符号对应的比特域取值不同。比如，一个上行符号对应的比特域取值为0表示该上行符号不能用于上行传输，一个上行符号对应的比特域取值为1表示该上行符号能用于上行传输。
在示例性实施方式中，符号配置信息可以包括N位比特信息，该N位比特信息与以下至少一项之间存在映射关系：不能用于上行传输的上行符号集合以及不能用于上行传输的符号总数；或者，该N位比特信息与以下至少一项之间存在映射关系：可用于上行传输的上行符号集合以及可用于上行传输的符号总数。其中，N可以为大于1的正整数。
在一种示例性实现方式中，以LTE系统为例，基站可以在LTE SIB1和MobilityControlInfo→RadioResourceConfigCommon中包含新增的符号配置信息进行下发，前者可以用于空闲态(Idle)的UE获取上行物理上行共享信道(Physical Uplink Shared Channel，PUSCH)的符号配置信息，后者可以用于切换UE获取目标小区的上行PUSCH的符号配置信息。
在本示例中，符号配置信息通过PUSCH符号配置字段(PUSCHSymbolConfig)携带。换言之，空闲态的UE可以根据SIB1中的PUSCHSymbolConfig，获知上行PUSCH可用的符号，切换UE可以根据MobilityControlInfo→RadioResourceConfigCommon中包含的PUSCHSymbolConfig，获知目标小区的上行PUSCH可用的符号。
在示例性实施方式中，在配置PUSCHSymbolConfig时，可以以10毫秒(ms)或者5ms为一个周期。在示例性实施方式中，上述周期的取值也可以通过在广播消息中增加字段通知给UE。
在示例性实施方式中，PUSCHSymbolConfig的配置方式包括以下两种。一种方式是：设置一个周期内的上行符号依次分别对应一个比特域，当上行符号对应的比特域的取值为0表示该上行符号不能用于上行传输，当上行符号对应的比特域的取值为1表示该上行符号可以用于上行传输。另一种方式是：采用N位比特信息表示一个周期内前多少个上行符号不能用于上行传输，其中，N的取值可以取决于一个周期内的上行符号总数。如表1所示，PUSCHSymbolConfig与不能用于上行传输的符号总数和不能传输PUSCH的符号集合之间存在映射关系。其中，不能用于上行传输的符号总数等于不能传输PUSCH的符号数目以及UpTPS上配置的符号数目(在本示例中，为2个符号)之和。
表1 SIB1上行传输符号的小区级配置
Figure PCTCN2018098965-appb-000001
在另一种示例性实现方式中，以LTE系统为例，基站可以通过UE级授权信息(比如，DCI)向UE通知可用的上行符号。其中，可以在上行调度对应的DCI中，例如，LTE的DCI0或DCI4等，增加新的比特位，表示一个或多个上行符号是否可以用于上行传输的情况。
在示例性实施方式中，由于DCI只是控制上行PUSCH传输，而上行PUSCH用于数据传输的符号为10个(扩展CP)或者12个(常规CP)，因此，可以配置10个或者12个比特域，每个比特域的取值表示对应的上行符号是否可用于PUSCH传输。
或者，可以采用4位比特信息(可以由PUSCH Symbol域携带)，该信息大小可以表示PUSCH信道上前多少个上行符号不能用于UE的PUSCH传输。如表2所示，PUSCH Symbol域的取值与不能用于PUSCH传输的符号总数和不能传输PUSCH的符号集合之间存在映射关系。
表2 UE级DCI的上行传输符号配置
Figure PCTCN2018098965-appb-000002
本实施例的通信方法同样适用于5G通信系统。
在本实施例中，在基站侧引入上行传输的符号自适应配置方式，该自适应配置方式可以包括UE级实时调整方式和小区级配置方式两种，这两种自适应配置方式可以单独使用，也可以同时使用。
图3为本公开另一实施例提供的通信方法的示例流程图。在本示例性实施例中，在LTE TDD配比2下，当存在大气波导干扰时，基站可以采用广播(SIB1)方式配置上行传输可用的上行符号。本实施例中，符号周期可以为5ms，且SIB1携带的PUSCHSymbolConfig可以表示一个周期内前多少个上行符号不能用于上行传输。
如图3所示，本实施例提供的通信方法包括以下步骤：
步骤301、基站打开大气波导检测功能。
步骤302、基站启动大气波导相关的干扰测量检测。例如，检测上行信道(例如，UpPTS、上行PUSCH、上行信道探测参考信号(Sounding Reference Signal，SRS)等)的干扰信息，判断是否满足大气波导的干扰特性。在示例性实施方式中，干扰测量检测可以包括阈值判断、随时间递减关联、干扰资源块(Resource  Block，RB)连续或者全带宽等方面的检测。
步骤303、基站判断是否存在符号级的大气波导干扰，如果存在，则进入步骤304，如果不存在，则结束。
步骤304、基站根据绝对干扰门限或者相对干扰门限，确定大气波导下受干扰的上行符号以及符号数。
步骤305、基站根据受干扰的上行符号及符号数，确定PUSCHSymbolConfig。
步骤306、基站发送SIB1，其中，SIB1中携带PUSCHSymbolConfig。
在步骤305中，可以根据确定的受干扰的上行符号以及符号数，基于表1确定PUSCHSymbolConfig的取值。比如，检测到一个周期内时隙#0中的上行符号#0受到干扰较大不能用于传输PUSCH，此时，时隙#0的符号#0及之前的UpTPS上配置的2个符号均不能用于传输PUSCH，故不能用于PUSCH传输的符号总数为3，基于表1可以确定PUSCHSymbolConfig的取值为0011。后续，UE接收到基站广播的SIB1后，可以根据SIB1中携带的PUSCHSymbolConfig，基于表1获知哪些上行符号不能用于传输PUSCH。
图4为本公开实施例提供的通信方法的流程图。在本示例性实施例中，在LTE TDD配比3下，当存在同频组网TDD配比2的交叉时隙干扰时，基站可以采用广播(SIB1)方式配置上行传输可用的上行符号。本实施例中，符号周期为10ms，且SIB1携带的PUSCHSymbolConfig可以表示一个周期内对应的上行符号是否可用于上行传输。
如图4所示，本实施例提供的通信方法包括以下步骤：
步骤401、基站打开上行干扰检测功能。
步骤402、基站启动干扰测量。例如，检测上行信道(例如，UpPTS、上行PUSCH以及上行SRS等)的干扰信息。
步骤403、基站判断是否存在符号级干扰，如果存在，则进入步骤404，如果不存在，则结束。
步骤404、基站根据绝对干扰门限或者相对干扰门限，确定受干扰的符号情况。
步骤405、基站根据受干扰的符号情况，确定PUSCHSymbolConfig。
步骤406、基站发送SIB1，其中，SIB1中携带PUSCHSymbolConfig。
在示例性实施方式中，TDD配比3在10ms内最大共38个上行符号(在扩展CP下，32个上行符号)，可以采用38个比特域依次(时间递延)表示每个上行符号 是否可用于传输。在示例性实施方式中，一个上行符号对应的比特域取值为0表示该上行符号不能用于上行传输，一个上行符号对应的比特域取值为1表示该上行符号可以用于上行传输。
图5为本公开实施例提供的通信方法的流程图。在本示例性实施例中，在LTE TDD配比2下，当存在大气波导干扰时，基站可以采用DCI控制UE级PUSCH传输可使用的符号，其中，DCI携带的PUSCH Symbol域指示前多少个上行符号不能用于PUSCH传输。
如图5所示，本实施例提供的通信方法包括以下步骤：
步骤501、基站打开大气波导检测功能。
步骤502、基站启动大气波导相关的干扰测量检测。例如，检测上行信道(例如，UpPTS、上行PUSCH以及上行SRS等)的干扰信息，判断是否满足大气波导的干扰特性。在示例性实施方式中，干扰测量检测可以包括阈值判断、随时间递减关联、干扰RB连续或者全带宽等方面的检测。
步骤503、基站判断是否存在符号级的大气波导干扰，如果存在，则进入步骤504，如果不存在，则结束。
步骤504、基站根据绝对干扰门限或者相对干扰门限，确定大气波导下受干扰的符号情况。
步骤505、基站判断UE是否存在上行调度，如果存在，则进入步骤506，如果不存在，则结束。
步骤506、当UE存在上行调度时，基站根据受干扰的符号数和每个符号上的干扰大小，以及UE距离基站的位置信息和上行功率余量等因素，并综合基站解调性能等，共同确定UE可以克服的干扰符号数以及干扰大小等，最终确定可用于PUSCH传输的符号。
步骤507、基站发送DCI，其中，DCI中携带符号配置信息。
在步骤506中，可以根据确定的受干扰的符号情况，基于表2确定DCI携带的PUSCH Symbol域的信息。比如，在检测到一个周期内时隙#0中的上行符号#0和#1受到干扰较大不能传输PUSCH时，基于表2可知，可以确定PUSCH Symbol域的取值为0010。后续，UE接收到基站下发的DCI后，可以根据DCI中携带的PUSCH Symbol域，基于表2获知哪些上行符号不能用于传输PUSCH。
图6为本公开另一实施例提供的通信方法的流程图。在本示例性实施例中，在LTE TDD配比2下，当存在大气波导干扰时，基站可以采用DCI控制UE级 PUSCH传输可使用的符号，且DCI中采用一个符号一个比特域的方式进行指示。
如图6所示，本实施例提供的通信方法包括以下步骤：
步骤601、基站打开大气波导检测功能。
步骤602、基站启动大气波导相关的干扰测量检测。
例如，检测上行信道(例如，UpPTS、上行PUSCH以及上行SRS等)的干扰信息，判断是否满足大气波导的干扰特性，其中可以包括阈值判断、随时间递减关联、干扰RB连续或者全带宽等方面的检测。
步骤603、基站判断是否存在符号级的大气波导干扰，如果存在，则进入步骤604，如果不存在，则结束。
步骤604、基站根据绝对干扰门限或者相对干扰门限，确定大气波导下受干扰的符号情况。
步骤605、基站判断UE是否存在上行调度，如果存在，则进入步骤606，如果不存在，则结束。
步骤606、当UE存在上行调度时，基站根据受干扰的符号数和每个符号上的干扰大小，以及UE距离基站的位置信息和上行功率余量等因素，并综合基站解调性能等，共同确定UE可以克服的干扰符号数以及干扰大小等，最终确定可用于PUSCH传输的符号。在步骤606中，可以将不能传输PUSCH的符号对应的比特域置为0，将能够传输PUSCH的符号对应的比特域置为1。
步骤607、基站发送DCI，其中，DCI中携带符号配置信息。
图7为本公开另一实施例提供的通信方法的流程图。在本示例性实施例中，在LTE TDD配比2下，当存在大气波导干扰时，基站可以采用小区级SIB1和UE级DCI共同控制上行传输可使用的符号。
如图7所示，本实施例提供的通信方法包括以下步骤：
步骤701、基站打开大气波导检测功能。
步骤702、基站启动大气波导相关的干扰测量检测。例如，检测上行信道(例如，UpPTS、上行PUSCH以及上行SRS等)的干扰信息，判断是否满足大气波导的干扰特性。在示例性实施方式中，干扰测量检测可以包括阈值判断、随时间递减关联、干扰RB连续或者全带宽等方面的检测。
步骤703、基站判断是否存在符号级的大气波导干扰，如果存在，则进入步骤704，如果不存在，则结束。
步骤704、基站根据绝对干扰门限或者相对干扰门限，确定大气波导下受干 扰的符号情况。
步骤705、基站根据受干扰的符号情况，确定PUSCHSymbolConfig。
在步骤705中，可以根据确定的受干扰的符号情况，基于表1确定PUSCHSymbolConfig的取值，并发送SIB1，其中，SIB1中携带PUSCHSymbolConfig。
步骤706、判断UE是否存在上行调度，如果存在，则进入步骤707，如果不存在，则结束；
步骤707、当UE存在上行调度时，基站根据受干扰的符号数和每个符号上的干扰大小，以及UE距离基站的位置信息和上行功率余量等因素，并综合基站解调性能等，共同确定UE可以克服的干扰符号数以及干扰大小等，最终确定可用于PUSCH传输的符号。在步骤707中，可以根据确定的受干扰的符号情况，基于表2确定DCI携带的PUSCH Symbol域信息。并发送DCI，其中，DCI中携带确定的PUSCH Symbol域信息。
图8为本公开另一实施例提供的通信方法的流程图。如图8所示，本实施例提供的通信方法，包括以下步骤：
步骤801、UE获取符号配置信息。
步骤802、根据符号配置信息，对上行数据进行上行传输。
在示例性实施方式中，符号配置信息用于指示以下至少之一：不能用于上行传输的上行符号以及可用于上行传输的上行符号。
在示例性实施方式中，步骤801可以包括以下之一：
UE从基站发送的小区级广播消息中，获取符号配置信息；
UE从基站下发的UE级授权信息中，获取符号配置信息；以及
UE根据基站发送的小区级广播消息以及UE级授权信息，确定符号配置信息。比如，UE可以确定上行传输可用的上行符号为小区级广播消息携带的符号配置信息和UE级授权信息携带的符号配置信息所指示的可用的上行符号的交集。
在示例性实施方式中，符号配置信息，可以包括：一个周期内每个上行符号对应的比特域取值，其中，可用于上行传输的上行符号对应的比特域取值与不能用于上行传输的上行符号对应的比特域取值不同。比如，一个上行符号对应的比特域取值为0表示该上行符号不能用于上行传输，一个上行符号对应的比特域取值为1表示该上行符号能用于上行传输。

在示例性实施方式中，上述方法还包括：当根据符号配置信息确定上行数据的映射资源位置不可用时，不发送该上行数据。
在本实施例中，UE可以根据基站发送的符号配置信息，确定上行数据的映射资源位置，进行数据映射并发送，如果没有符号可以传输上行数据，则UE不传输对应的上行数据。
图9为本公开实施例提供的通信方法的流程图。在本示例性实施例中，在LTE TDD配比2下，当存在符号级干扰时，UE可以根据SIB1中的PUSCHSymbolConfig确定可以用于PUSCH传输的符号。
如图9所示，本实施例提供的通信方法包括以下步骤：
步骤901、判断UE是否存在上行传输，如果存在，进入步骤902，如果不存在，则结束；
步骤902、根据SIB1中的PUSCHSymbolConfig确定可用于PUSCH传输的符号。比如，SIB1中的PUSCHSymbolConfig的取值为0011，则UE基于表1可以获知一个周期内的前3个上行符号不能用于PUSCH传输，分别为时隙#0中的上行符号#0以及UpPTS上配置的2个上行符号。
步骤903、根据符号配置信息，对上行数据进行上行传输。
