Description

一种上行信息的传输方法、第一通信设备和第二通信设备
本申请要求于2017年11月15日提交中国专利局、申请号为201711132492.X、申请名称为“一种上行信息的传输方法、第一通信设备和第二通信设备”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
本申请的实施例涉及通信系统，尤其是涉及一种上行信息的传输方法、第一通信设备和第二通信设备。
背景技术
第五代移动通信系统(The 5 th Generation，5G)支持灵活的时隙结构，一个时隙包含14个符号，在一个时隙中，每一个符号都可以用于上行传输或者下行传输。基站会向终端发送时隙格式信息(Slot Format related Information，SFI)，用以告知终端时隙的结构，例如，时隙的哪些符号用于上行传输，哪些符号用于下行传输以及哪些符号是未知(unknown)的格式，对于未知格式的符号，终端不会发送或者接收信息，SFI可以包含在基站向一组终端发送的组公共物理下行控制信道(Group Common Physical Downlink Control Channel，Group Common PDCCH)中，用以告知一组终端基站调度的时隙格式。
当终端将要向基站发送上行信息时，基站可以为终端调度上行资源，以用于终端在基站分配的上行资源上向基站发送上行信息，例如上行数据或上行控制信息等。当基站发给终端的SFI指示的资源格式是用于下行传输或者未知时，则无法用于上行传输，此时，如果SFI指示的格式为下行传输或者未知的资源恰好是基站调度给终端用于上行信息传输的资源，即基站分配的上行资源与SFI指示的下行资源或未知资源相冲突时，终端则无法判断在哪些资源上向基站发送上行信息。

下面结合具体例子，以第二通信设备和第一通信设备为例，更加详细地描述本申请的实施例。
图2为本申请实施例提供的一种上行信息的传输方法、第一通信设备、第二通信设备及系统。如图6所示，第一通信设备包括接收单元61、确定单元62以及发送单元63，其中，接收单元61与发送单元63可以由收发单元代替。如图7所示，第二通信设备包括发送单元71、确定单元72以及接收单元73，其中，发送单元71与接收单元73可以由收发单元代替。
当第二通信设备为网络设备或者基站时，当第一通信设备为终端设备或者用户设备时，确定单元62或确定单元72可以为处理器，接收单元61、接收单元73、发送单元63、发送单元71或者收发单元可以为收发器，此收发器可以为射频电路，当第一通信设备包含存储单元时，该存储单元用于存储计算机指令，该处理器与存储器通信连接，处理器执行存储器存储的计算机指令，使第一通信设备或第二通信设备执行图2实施例涉及的方法。其中，处理器可以是一个通用中央处理器(CPU)，微处理器，特定应用集成电路(application-specific integrated circuit，ASIC)。
当第一通信设备或第二通信设备为芯片时，所述确定单元62或确定单元72例如可以是处理器，接收单元61或接收单元73可以是输入接口、管脚或电路等，发送单元63或发送单元71可以是输出接口、管脚或电路等，所述收发单元例如可以是输入/输出接口、管脚或电路等。该处理单元可执行存储单元存储的计算机执行指令，以使该第一通信设备或第二通信设备内的芯片执行图2所涉及的方法。可选地，所述存储单元为所述芯片内的 存储单元，如寄存器、缓存等，所述存储单元还可以是所述终端内的位于所述芯片外部的存储单元，如只读存储器(read-only memory，ROM)或可存储静态信息和指令的其他类型的静态存储设备，随机存取存储器(random access memory，RAM)等。
图2实施例所涉及的上行信息的传输方法的具体步骤如下：
步骤21，第二通信设备的发送单元71在时隙m向第一通信设备发送第一控制信息，第一通信设备的接收单元61在时隙m从第二通信设备接收第一控制信息。可选的，所述时隙包括x个符号(symbol)，所述时隙也可以由其它时间长度的时间粒度代替，例如，所述时隙可以由子帧或微时隙(mini slot)代替，一个时隙包括14或者12个符号，下面以1个时隙包含14个符号为例进行说明。第一控制信息用于指示在时隙m+k上用于上行信息传输的第一时间资源，所述第一时间资源包括至少一个所述符号，所述m和k为非负整数，x为正整数，第一控制信息优选为上行调度授权(UL Grant)，下面以第一控制信息为UL Grant为例进行说明。
例如图3或4所示，第二通信设备在时隙m向第一通信设备发送UL Grant，用以调度第一通信设备在时隙m+k的符号0至符号13(如图3所示)向第二通信设备发送上行信息，或者用以调度第一通信设备在时隙m+k的符号0至符号6(如图4所示)向第二通信设备发送上行信息。
步骤22，第二通信设备的发送单元71在时隙n向第一通信设备发送第二控制信息，第一通信设备的接收单元61在时隙n从第二通信设备接收第二控制信息，所述n为非负整数，所述时隙n在所述时隙m+k之前，即第二通信设备发送第二控制信息所在的时隙n应当在第二通信设备从第一通信设备接收上行信息所在的时隙m+k之前。第二控制信息用于指示时隙m+k包含的x个符号的类型，所述类型包括上行、下行或未知，第二控制信息可以为SFI，下面以第二控制信息是SFI为例进行说明。SFI可以指示时隙m+k上哪些符号是用于上行传输、哪些符号是用于下行传输，即SFI可以指示时隙m+k上包含的某个符号是用于上行传输还是下行传输，当然，SFI还可以指示时隙m+k上哪些符号的类型是未知，即第一通信设备不会在类型为未知的符号上向基站发送信息或者从基站接收信息。未知类型也可以由其它的类型所代替，例如侧行(sidelink)，又如由信令指示为下行或者上行。优选的，SFI可以指示某个时隙所包含的任意一个符号的具体的类型。所述时隙m+k上类型为上行的至少一个符号组成第二时间资源。
步骤23，第二通信设备的确定单元72根据所述第一时间资源和所述第二时间资源确定第三时间资源。
步骤24，第一通信设备的确定单元62根据所述第一时间资源和所述第二时间资源确定第三时间资源。
步骤23以及步骤24的先后顺序没有限定，在步骤23以及步骤24中，第三时间资源为所述时隙m+k上用于上行信息传输的至少一个符号。上行信息包括上行数据或上行控制信息，上行控制信息包括调度请求(Scheduling Request，SR)、反馈信息(ACK或NACK)或信道状态信息(Channel State Information，CSI)。
如图3所示，当第一时间资源与第二时间资源包含相同的符号时，第三时间资源为所述第一时间资源与所述第二时间资源包含的相同的符号，所述相同的符号指的是同时属于第一时间资源和第二时间资源的至少一个符号。例如，在图3中，第二通信设备向第一通 信设备发送的UL Grant指示在时隙m+k上用于上行信息传输的资源为符号0至符号13，即第一时间资源为符号0至符号13，而第二通信设备向第一通信设备发送的SFI指示在时隙m+k上符号0至符号5的类型为下行，符号6为未知，符号7至符号13为上行，即符号7至符号13组成第二时间资源，则第三时间资源为第一时间资源和第二时间资源所包含的相同的符号7至符号13。第一通信设备的发送单元63在所述第一时间资源与所述第二时间资源包含的相同的符号上(即，符号7至符号13)向所述第二通信设备发送上行信息。
如图4所示，当第一时间资源与所述第二时间资源不包含相同的符号时，所述第二时间资源包含的符号数量小于所述第一时间资源包含的符号数量，所述第三时间资源为所述第二时间资源。例如，在图4中，第二通信设备向第一通信设备发送的UL Grant指示在时隙m+k上用于上行信息传输的资源为符号0至符号6，即第一时间资源为符号0至符号6，而第二通信设备向第一通信设备发送的SFI指示在时隙m+k上符号0至符号8的类型为下行，符号9为未知，符号10至符号13为上行，即符号10至符号13组成第二时间资源，第二时间资源包含4个符号，第一时间资源包含7个符号，则第三时间资源为第二时间资源所包含的符号10至符号13。第一通信设备的发送单元63在所述第二时间资源(即，符号10至符号13)上向所述第二通信设备发送上行信息。
如图5所示，当第一时间资源与所述第二时间资源不包含相同的符号时，所述第二时间资源包含的符号数量大于或等于所述第一时间资源包含的符号数量，所述第三时间资源为所述第二时间资源的预定义的M个符号，M为正整数，所述M为所述第一时间资所包含的符号的数量，所述预定义的M个符号为所述第二时间资源的前M个符号，所述第二时间资源的后M个符号，或所述第二时间资源的任意M个符号。例如，在图5中，第二通信设备向第一通信设备发送的UL Grant指示在时隙m+k用于上行信息传输的资源为符号0至符号2，即第一时间资源为符号0至符号2，而第二通信设备向第一通信设备发送的SFI指示在时隙m+k上符号0至符号8的类型为下行，符号9为未知，符号10至符号13为上行，即符号10至符号13组成第二时间资源，第二时间资源包含4个符号，第一时间资源包含3个符号，则第三时间资源为第二时间资源所包含的符号10至符号12，或符号11至符号13。第一通信设备的发送单元63在所述第二时间资源的预定义的M个符号上向所述第二通信设备发送上行信息，第二通信设备的接收单元73在所述第二时间资源的预定义的M个符号上从第一通信设备接收所述上行信息。
当所述上行信息是上行控制信息时，上行控制信息包括SR信息、ACK/NACK信息或CSI信息，不同的上行控制信息是具有不同优先级的，优选的优先级顺序为SR>ACK/NACK>CSI，如果第三时间资源有限，不足以使第一通信设备发送全部的上行控制信息，则第一通信设备会按照上行控制信息的优先级，按照优先级从低到高的顺序放弃传输优先级低的上行控制信息，只发送部分优先级高的上行控制信息。第一通信设备也可以将此上行控制信息随路(piggyback)到上行数据后面向第二通信设备发送。由此，第一通信设备可以确保优先级高的上行控制信息能够完整、准确的发送到第二通信设备。
如果第二通信设备发送给第一通信设备的UL Grant指示的用于上行信息传输的资源只包含一个传输块(Transport Block，TB)，且此传输块包含该传输块的关键信息，例如，系统位，则第一通信设备放弃利用此UL Grant调度的上行资源传输上行信息，而等待第二 通信设备为第一通信设备再次调度上行资源以用于上行信息的传输。
步骤25，第一通信设备的发送单元63在所述第三时间资源向第二通信设备发送上行信息，第二通信设备的接收单元73在所述第三时间资源从第一通信设备接收所述上行信息。
可选的，在所述第一通信设备在所述第三时间资源向所述第二通信设备发送上行信息之前，第一通信设备的确定单元62会判断第三时间资源是否满足第一条件，当第三时间资源满足第一条件时，第一通信设备的发送单元63在第三时间资源向第二通信设备发送上行信息，在所述第二通信设备在所述第三时间资源从所述第一通信设备接收上行信息之前，第二通信设备的确定单元72会判断第三时间资源是否满足第一条件，当第三时间资源满足第一条件时，第二通信设备的接收单元73则在第三时间资源从第一通信设备接收上行信息。第一条件可以为所述第三时间资源所包含的符号个数大于或等于第一阈值。其中，第一阈值可以为x个符号，x为自然数，第一阈值可以是由协议预定义的，也可以是由第二通信设备发送给第一通信设备的。由此，可以通过第一阈值的设定，确保第一通信设备只在具有足够的上行资源的时候才会向基站发送上行信息，以保证所发送上行信息的完整性和准确性。
第一条件还可以为所述第三时间资源所包含的符号个数与所述第一时间资源所包含的符号个数的比值大于或等于第二阈值。其中，第二阈值为真分数，第二阈值可以是由协议预定义的，也可以是由第二通信设备发送给第一通信设备的。由此，可以通过第二阈值的设定，确保第一通信设备只在具有占第一时间资源足够比例的上行资源的时候才会向基站发送上行信息，以保证所发送上行信息的完整性和准确性。
当时间N大于或等于所述第一通信设备的发送单元63准备发送上行信息所需要的最短处理时间时，优选的，所述第一通信设备的发送单元63以速率匹配的方式向所述第二通信设备发送上行信息，所述第二通信设备的接收单元73以速率匹配的方式解码从所述第一通信设备接收的上行信息。速率匹配是指根据传输资源的大小来确定待发送信息的编码方式和/或调制方式的信息发送方式，即第一通信设备会根据第三资源的大小对上行信息进行编码和/或调制，然后再将编码后和/或调制后的上行信息发送给第二通信设备。以图3为例，第二通信设备调度的传输上行信息的资源原本为第一时间资源的14个符号，但是由于SFI指示的上行资源只有7个符号(符号7至符号13)，因此，第一通信设备会根据实际可用的上行资源7个符号对将要发送的上行信息进行编码和/或调制，然后再将编码后和/或调制后的上行信息发送给第二通信设备。当然，当时间N大于或等于所述第一通信设备的发送单元63准备发送上行信息所需要的最短处理时间时，第一通信设备也可以以打孔的方式向第二通信设备发送上行信息。所述最短处理时间为第一通信设备为了发送上行信息而对上行信息进行的编码和速率匹配的最短时间，所述时间N为时隙n与时隙m+k之间的时间间隔，此时间间隔也可以为时隙n与时隙m+k之间间隔的时隙数量或符号数量。第二通信设备的接收单元73可以从第一通信设备接收所述第一通信设备的能力信息，所述能力信息用于指示所述第一通信设备准备发送上行信息所需要的最短处理时间。由此，可以根据时隙n与时隙m+k的时间间隔和所述第一通信设备的处理时间更加合理的选择发送上行信息的方式，以增强上行信息发送的完整性和准确性。
当时间N小于所述最短处理时间时，所述第一通信设备的发送单元63以打孔的方式 向所述第二通信设备发送上行信息，所述第二通信设备的接收单元73以打孔的方式解码从所述第一通信设备接收的上行信息。打孔是指将待发送信息的一部分丢弃，而只传输剩余部分的信息发送方式，即第一通信设备会根据第三资源的大小对上行信息的一部分进行丢弃，即打孔，然后再将打孔后剩余的上行信息发送给第二通信设备。以图4为例，第二通信设备调度的传输上行信息的资源原本为第一时间资源的7个符号(符号0至符号6)，但是由于SFI指示的上行资源只有4个符号(符号10至符号13)，因此，真正可用于上行信息传输的资源只占第二通信设备调度的资源的4/7，因此，第一通信设备会将上行信息的3/7打掉或丢弃，然后只将剩余的4/7发送给第二通信设备。由此，可以根据时隙n与时隙m+k的时间间隔和所述第一通信设备的处理时间更加合理的选择发送上行信息的方式，以增强上行信息发送的完整性和准确性。
当第三时间资源所包含的符号个数与所述第一时间资源所包含的符号个数的比值小于或等于第三阈值时，所述第一通信设备的发送单元63以速率匹配的方式向所述第二通信设备发送上行信息，所述第二通信设备的接收单元73以速率匹配的方式解码从所述第一通信设备接收的上行信息。当所述第三时间资源所包含的符号个数与所述第一时间资源所包含的符号个数的比值大于第三阈值时，所述第一通信设备的发送单元63以打孔的方式向所述第二通信设备发送上行信息，所述第二通信设备的接收单元73以打孔的方式解码从所述第一通信设备接收的上行信息。其中，第三阈值为真分数，第三阈值可以是由协议预定义的，也可以是由第二通信设备发送给第一通信设备的。
第一通信设备所包括的接收单元61可以由接收器替换，确定单元62可以由处理器替换，发送单元63可以由发送器替换。第二通信设备所包括的发送单元71可以由发送器替换，确定单元72可以由处理器替换，接收单元73可以由接收器替换。第一通信设备或者第二通信设备也可以是一种芯片或者片上系统以完成图2实施例所示的方法。
通过本申请实施例，第一通信设备和第二通信设备会根据UL Grant指示的第一时间资源和SFI指示的第二时间资源确定实际可用于上行信息传输的第三时间资源，在第二通信设备分配的上行资源与SFI指示的下行资源或未知资源相冲突时，第一通信设备和第二通信设备可以确定第三时间资源为上行信息的传输资源，并在第三时间资源上完成上行信息的传输。
