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,第一通信设备的发送单元91在第一资源上向第二通信设备发送第一指示信息,第二通信设备的接收单元101在第一资源上从第一通信设备接收所述第一指示信息。第一指示信息用于指示所述第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系,所述位置关系为频分复用(Frequency Division Multiplexing,FDM)关系或者时分复用(Time Division Multiplexing,FDM)关系。第一通信设备将在所述第一资源上向第二通信设备发送控制信息和数据。可选的,第一指示信息用于指示如下的一种:第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源满足频分复用关系或第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源满足时分复用关系。可选的,如果第一通信设备没有向第二通信设备发送第一指示信息或第二通信设备没有从第一通信设备接收到第一指示信息,则第一通信设备默认按照FDM的位置关系向第二通信设备发送控制信息和数据和/或第二通信设备默认按照FDM的位置关系从第一通信设备接收控制信息和数据。
第一通信设备在第一资源上向第二通信设备发送第一指示信息包括:所述第一通信 设备在所述第一资源包含的第二资源上向第二通信设备发送第一指示信息,所述第二资源为所述第一资源的由在时域上第一个可解码的符号以及在频域上序号最小的资源块RB所构成的资源。
定义第一时频资源单元,此第一时频资源单元包括时域上的m个符号和频域上的n个资源块(Resource Block,RB),第一时频资源单元为完成V2X通信的最小时频资源单元,即传输V2X控制信息和V2X数据的时频资源为所述第一时频资源单元的正整数倍。例如,在时域上,第一时频资源单元可以为一个子帧、一个时隙(slot)或一个微时隙(mini slot),其中,一个时隙包括14个符号或12个符号,一个微时隙包括的符号数小于一个时隙包括的符号数,例如,一个微时隙包括7个符号或6个符号。在频域上,第一时频资源单元包含n个连续的RB。则第一资源包括至少一个所述第一时频资源单元,例如,第一资源包括时域上的所述m个符号,所述第一资源包括频域上的p个RB,p为n的正整数倍,即第一资源是在频域上包括至少一个第一时频资源单元,而在时域上只包含一个第一时频资源单元。其中,所述m、n以及p均为正整数。
第一通信设备的发送单元91在第一资源上向第二通信设备发送第一指示信息包括:第一通信设备的发送单元91在第二资源上向第二通信设备发送第一指示信息,所述第二资源在时域上为所述第一资源所包含的m个符号中第一个可解码的符号,且第二资源在频域上为所述第一资源所包含的p个RB中序号最小的RB。由此,第二通信设备在最先可以解码的资源位置上从第一通信设备接收第一指示信息,能够尽可能早的解码所述第一指示信息。
由于第一通信设备向第二通信设备发送控制信息的资源与发送数据的资源可以为频分复用的位置关系,也可以是时分复用的位置关系,因此,第二通信设备必须在解码控制信息和数据之前就获知发送控制信息的资源与发送数据的资源的位置关系是频分复用关系还是时分复用关系,因此,可选的,在第一资源上定义一个公共控制区域(Common Control Region,CCR),此公共控制区域为第一资源所包含的m个符号中的前x个符号,为第一资源所包含的p个RB中序号最小的前y个RB,x和y为正整数。则第一指示信息可以在所述公共控制区域内的任何一块资源上进行传输,也可以在公共控制区域的第一个可解码的符号以及序号最小的RB上进行传输。上述第一个可解码的符号可以为所述m个符号或所述x符号中的第一个符号。上述第一个可解码的符号也可以是所述m个符号或所述x符号中的第二个符号,此时,所述m个符号或所述x符号中的第一个符号可以用于自动增益控制(Automatic Gain Control,AGC)信息的传输。
第一指示信息可以为SA类型指示(SA Type Indicator,STI)信息,第一指示信息可以由1个比特来表示,例如,“1”表示传输控制信息的资源与传输数据的资源的位置关系为FDM形式,“0”表示传输控制信息的资源与传输数据的资源的位置关系为TDM形式,或者相反。第一指示信息可以经过码率为k的编码器形成1/k比特的码字,再经过调制形成z个符号,z为正整数,调制例如可以为二相移相键控(Binary Phase Shift Keying,BPSK)调制、正交相移键控(Quadrature Phase Shift Keying,QPSK)调制、16相正交振幅调制(16Quadrature Amplitude Modulation,16QAM)、64相正交振幅调制(64 Quadrature Amplitude Modulation,64QAM)或256相正交振幅调制(256 Quadrature Amplitude Modulation,256QAM),可选的,在调制前,还可以对1/k比特的码字进行加扰。然后,可以对调制后的z个符号均匀地映射到传输第一指示信息的资源的RB所 包含的多个资源单元(Resource Element,RE)上。
步骤22,第一通信设备的发送单元91在第一资源上向所述第二通信设备发送控制信息,第二通信设备的接收单元101在第一资源上从所述第一通信设备接收控制信息。此控制信息可以为SA信息,此控制信息可以在物理侧行控制信道(Physical Sidelink Control Channel,PSCCH)上传输。
步骤23,第一通信设备的发送单元91根据所述控制信息在所述第一资源上向所述第二通信设备发送数据,此数据可以在物理侧行共享信道(Physical Sidelink Shared Channel,PSSCH)上传输,第二通信设备的接收单元101根据所述控制信息在所述第一资源上从所述第二通信设备接收数据。所述第一通信设备向所述第二通信设备发送控制信息的资源与所述第一通信设备根据所述控制信息向所述第二通信设备发送数据的资源的位置关系满足所述第一指示信息指示的位置关系。例如,第一指示信息指示第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系为FDM形式,则第二通信设备在接收到第一指示信息之后便可以得知第一通信设备发送的控制信息的资源与发送数据的资源为FDM形式;或者,第一指示信息指示第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系为TDM形式,则第二通信设备在接收到第一指示信息之后便可以得知第一通信设备发送的控制信息的资源与发送数据的资源为TDM形式。
通过本申请实施例,第一通信设备会将发送控制信息的资源与发送数据的资源的位置关系通过第一指示信息告知第二通信设备,而不再是以固定的方式传输控制信息和数据,第二通信设备可以在接收到第一指示信息后根据其所指示的发送控制信息的资源与发送数据的资源的位置关系来接收第一通信设备发送的控制信息和数据,由此提高了第一通信设备发送控制信息和数据的灵活性。
第一通信设备可以根据待发送数据的业务类型、数据包大小和/或时延要求等信息确定待发送控制信息与待发送数据采用FDM形式或者TDM形式传输,并通过第一指示信息通知第二通信设备。第一通信设备待发送控制信息与待发送数据采用FDM形式或者TDM形式传输也可以由网络设备的确定单元112确定,并通过发送单元111发送给第一通信设备,再由第一通信设备通过第一指示信息通知第二通信设备,当然,也可以由基站的发送单元111通知第一通信设备和第二通信设备。由此,可以根据具体数据业务的需求采用FDM形式或者TDM形式传输控制信息或数据,提高了V2X信息传输的灵活性。
第一指示信息指示所述第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系为频分复用关系,第一通信设备的发送单元91在第一资源上向所述第二通信设备发送控制信息包括:所述第一通信设备的发送单元91在所述p个RB中的q个RB上向所述第二通信设备发送控制信息,所述q为正整数;所述第一通信设备根据所述控制信息在所述第一资源上向所述第二通信设备发送数据包括:所述第一通信设备根据所述控制信息在所述p个RB中剩余的p-q个RB上向所述第二通信设备发送数据。例如图3所示,第一资源包含2个第一时频资源单元,其中第一时频资源单元包含一个时隙,例如14个符号,且包含12个RB,因此,m为14,n为12,p为24,q为2,则第一资源包含14个符号和24个RB,第一指示信息在第一资源的第1个符号和第1个RB上由第一通信设备向第二通信设备发送,第一通信设备在第一资源包含的24个RB 中序号最小的2个RB以及所有的14个符号构成的时频资源上向第二通信设备发送控制信息,第一通信设备在第一资源包含的24个RB中除序号最小的2个RB外的22个RB以及所有的14个符号构成的时频资源上向第二通信设备发送数据。当然,第一资源也可以只包含1个第一时频资源单元。
在第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系为频分复用FDM关系时,第二通信设备需要对控制信息缓存以及对数据缓存,第二通信设备将控制信息全部接收完毕需要经历14个符号,然后,第二通信设备会对控制信息进行解码,然后根据解码后的控制信息对缓存的数据进行解码。由于第二通信设备需要先将控制信息和数据缓存,然后才能对控制信息和数据解码,因此,控制信息与数据采用FDM形式传输形式适用于对延时要求不高的数据业务的传输。
第一指示信息指示所述第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系为时分复用关系,第一通信设备的发送单元91在第一资源上向所述第二通信设备发送控制信息包括:所述第一通信设备的发送单元91在所述m个符号中的前r个符号上向所述第二通信设备发送控制信息,其中,r为正整数。第一通信设备根据所述控制信息在所述第一资源上向所述第二通信设备发送数据包括:所述第一通信设备根据所述控制信息在所述m个符号中剩余的m-r个符号上向所述第二通信设备发送数据。例如图4所示,第一资源包含1个第一时频资源单元,其中第一时频资源单元包含一个时隙,例如14个符号,且包含12个RB,因此,m为14,n为12,p为12,r为2,则第一资源包含14个符号和12个RB,则第一指示信息在第一资源的第1个符号和第1个RB上由第一通信设备向第二通信设备发送,第一通信设备的发送单元91在所述14个符号中的前2个符号上向所述第二通信设备发送控制信息,所述第一通信设备根据所述控制信息在所述14个符号中剩余的12个符号上向所述第二通信设备发送数据。
又例如图5所示,第一资源包含2个第一时频资源单元,其中第一时频资源单元包含一个时隙,例如14个符号,且包含12个RB,因此,m为14,n为12,p为24,r为2,则第一资源包含14个符号和24个RB,则第一指示信息在第一资源的第1个符号和第1个RB上由第一通信设备向第二通信设备发送,第一通信设备的发送单元91在所述14个符号中的前2个符号以及前12个RB构成的时频资源上向所述第二通信设备发送控制信息,当然,也可以在所述14个符号中的前2个符号以及所有24个RB构成的时频资源上向所述第二通信设备发送控制信息,所述第一通信设备根据所述控制信息在所述14个符号中剩余的12个符号和所有24个符号构成的时频资源上向所述第二通信设备发送数据。
在第一通信设备发送控制信息的资源与所述第一通信设备发送数据的资源的位置关系为时分复用TDM关系时,第二通信设备只需要经过2个符号就可以对控制信息接收完毕,然后第二通信设备就可以根据接收到的控制信息接收数据。由于控制信息与数据在时域上是先后传输的,第二通信设备可以仅用2个符号的时间就接收控制信息,然后就可以对数据解码,因此,控制信息与数据采用TDM形式传输形式适用于对延时要求高的数据业务的传输。
第一通信设备还可以从第二通信设备接收应答信息,此应答信息用于第二通信设备向第一通信设备反馈是否正确地接收到了第一通信设备发送的数据,此应答信息包括确认(acknowledgement,ACK)信息或否定性确认(negative acknowledgement,NACK) 信息。在图4实施例的基础上,应答信息的传输例如图6所示,第一通信设备的发送单元91根据所述控制信息在所述m个符号中剩余的m-r个符号的第一符号集合上向所述第二通信设备发送数据,所述第一通信设备的接收单元93根据所述控制信息在所述m个符号中剩余的m-r个符号的第二符号集合上从所述第二通信设备接收所述应答信息,所述第一符号集合与所述第二符号集合不包含相同的符号。如图6所示,在数据和应答信息之间,还可以设置保护间隔Gap,此保护间隔占用至少1个符号。
在图5实施例的基础上,应答信息的传输又如图7所示,第一通信设备的发送单元91根据所述控制信息在所述m个符号中剩余的m-r个符号的第一符号集合上向所述第二通信设备发送数据,所述第一通信设备的接收单元93根据所述控制信息在所述m个符号中剩余的m-r个符号的第二符号集合上从所述第二通信设备接收所述应答信息,所述第一符号集合与所述第二符号集合不包含相同的符号。如图7所示,在数据和应答信息之间,还可以设置保护间隔Gap,此保护间隔占用至少1个符号。
第一通信设备在所述m个符号中的前r个符号上向所述第二通信设备发送控制信息包括:所述第一通信设备的发送单元91在所述前r个符号中除所述前r个符号的第一个符号之外的符号上向所述第二通信设备发送控制信息;所述第一通信设备的发送单元91在所述前r个符号的第一个符号上向所述第二通信设备发送AGC信息。
上述实施例中提到的控制信息包括时隙格式指示(Slot Format Indicator,SFI)信息、循环前缀指示信息、子载波间隔指示信息或时隙指示信息中的至少一个信息。
时隙格式指示信息用于指示传输所述控制信息的符号、传输所述数据的符号或传输所述应答信息的符号中的至少一个,即时隙格式指示信息指示了第一资源所在时隙包含的不同符号的用途,例如图8所示,时隙格式指示信息指示符号0用于AGC,符号1和2用于控制信息传输,符号3至9用于数据传输,符号10和13用于保护间隔,符号11和12用于应答信息传输。循环前缀指示信息用于指示循环前缀的类型,例如可以为正常的循环前缀或延长的循环前缀。子载波间隔指示信息用于指示相邻子载波的频率间隔。时隙指示信息用于指示传输所述控制信息或所述数据的资源在时域上的最小单元是时隙或者微时隙。
