所述第一标识信息中包含第一标识,该第一标识可以为混合自动重传请求进程编号,第一标识还可以为新数据指示或子载波编号、小区编号等其中的一个。例如,第一标识信息同时包含混合自动重传请求进程编号及新数据指示,当第一标识信息的混合自动重传请求进程编号与第二标识信息的混合自动重传请求进程编号相同或根据预定义的对应关系所对应,且第二标识信息中的新数据指示NDI指示第二数据为新数据时,第一终端装置可以判断第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,因此可以进一步对这两份数据进行合并,进而提升数据块或信源数据或原始数据的恢复成功率。数据合并可以包括软合并或者选择性合并等等。
步骤S202,第二终端装置的发送单元920向第一终端装置发送第二数据和所述第二数据的第二标识信息,第一终端装置的接收单元710接收来自该第二终端装置的第二数据和第二数据的第二标识信息。该第二标识信息用于标识所述第二数据,第二数据为根据所述第一数据确定的数据,所述第二标识信息为根据所述第一标识信息确定的标识信息,用于标识所述第一网络装置发送至所述第一终端装置的所述第一数据的所述第一标识信息和所述第二标识信息还用于确定所述第一网络装置发送至所述第一终端装置的所述第一数据与所述第二数据是否属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。可选的,第一终端装置还可以结合协议预定义内容或网络配置的高层信 令或物理层信令共同判断第一数据与第二数据是否属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。
可选的,第二终端装置的发送单元920在侧行链路上向第一终端装置发送第二数据及第二标识信息,第二数据承载在侧行物理共享信道(Physical Sidelink Shared Channel,PSSCH)中,第二指示信息承载在侧行物理控制信道(Physical Sidelink Control Channel,PSCCH)中。第二数据与第二标识信息还可以共同承载在侧行物理共享信道中或者侧行物理控制信道中。
第二数据可以是第二终端装置对接收到的第一数据进行解码后再编码得到的新的数据,因此第二数据与第一数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,对第二数据与第一数据进行共同解码相比于只对第一数据进行解码具备更高的解码成功率。
步骤S203,第一终端装置的确定单元720根据所述第一标识信息和所述第二标识信息确定所述第一数据与第二数据属于同一数据。
在步骤S203后,根据本申请实施例,第一终端装置的确定单元720还可以合并所述第一数据和所述第二数据。所述合并方式可以是对于两份数据的一部分进行合并或对两份数据进行合并。优选的,第一终端装置对第一数据及第二数据进行联合处理,联合处理后的信干噪比高于单分数据信号,从合并后的数据信号中恢复传输块的成功率会大大增加。可选的,如果合并失败,还可以进行多次接收和合并过程。可选的,第一终端装置也可以把来自第一网络装置的属于同一数据的多份数据信号进行合并,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。可选的,第一终端装置也可以把来自第二终端装置的来自同一个传输块TB、或同一个信源数据或同一个原始数据的多份数据信号进行合并。
可选的,第一终端装置合并处理的数据并不仅限于分别来自网络装置和终端装置。第一终端装置还可以对来自基站的多份来自同一数据的信号进行合并处理,或对于来自第二终端装置的多份来自同一数据的信号进行合并处理,或可以对于来自不同终端装置,例如,第二终端装置与第三终端装置的多份来自同一数据的信号进行合并处理来获得有益效果,这里来自同一数据是指来自同一个传输块TB、或同一个信源数据或同一个原始数据。
第一终端装置的确定单元720根据第一标识信息和第二标识信息确定第一数据与第二数据属于同一数据的方式是多样的。
方式A:第一标识信息包括第一标识,第一标识用于标识所述第一数据,第二标识信息包括第二标识,第二标识用于标识所述第二数据,第二标识与所述第一标识为同一个标识;此时,第一终端装置根据所述第一标识与所述第二标识确定所述第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。可选的,第二标识还可以与第一标识不同,第二标识可以是第二终端装置根据第一标识确定的与第一标 识不同的标识。可选的,第二数据本身包含第一标识,第二标识是侧行链路上的额外指示信息,第二标识还隐含了一个含义,即这个第二数据承载的是转发的传输块,而不是非转发的传输块,即第一标识信息里的第一标识,用于标识第一数据。
第二标识信息里的第一标识,用于标识第二数据本身,例如第二标识信息中的第一标识是HARQ IDss=5,该HARQ IDss与第二标识信息中的第二标识HARQ IDs无关,该HARQ IDss与第一标识信息中的第二标识HARQ IDu也无关,它的确定不依赖于第一标识信息以及第二标识信息中的任意标识,因此该第二标识信息中的第一标识不用于判断第二数据与第一数据是否对应。而第二标识信息里的第二标识是根据第一标识信息中的第一标识确定的,该第二标识信息中的第二标识用于标识该第二数据具体与哪份第一数据对应,即与哪个第一数据来自同一个传输块(Transport Block,TB)、或同一个信源数据或同一个原始数据。
例如,第一终端装置从下行链路接收的数据为数据A,其混合自动重传请求进程编号,HARQ IDu=1,其中HARQ IDu代表下行链路数据对应的HARQ ID,第一终端装置在侧行链路上分别接收了数据B、数据C及数据D,其中数据B对应的UU链路关联HARQ IDs=1,数据C对应的UU链路关联HARQ IDs=2,数据D对应的UU链路关联HARQ IDs=1,其中HARQ IDs代表侧行链路数据对应的HARQ ID。则第一终端装置根据各个HARQ ID判断数据B、数据D与数据A来自同一个传输块TB、或同一个信源数据或同一个原始数据,数据A、数据B、数据D本质上是由同一个传输块TB或同一个信源数据或同一个原始数据通过一种或多种编码方式形成的,例如,根据100比特的信源数据,分别通过编码方式1、编码方式2、编码方式3进行编码得到了数据A、数据B、数据D,数据A与数据B与数据D都源于同一个100比特的信源数据,可以对这三份数据进行合并,获得合并带来的数据恢复率提升的效果。

数据B HARQ IDs=1
数据C HARQ IDs=2
数据D HARQ IDs=1
方式B:第一标识信息包括第一标识,第一标识用于标识所述第一数据,第二标识信息包括第二标识,第二标识用于标识第二数据,第二标识还用于标识第一数据与第二数据的对应关系;此时,第一终端装置根据第一标识与所述第二标识及所述第一标识与所述第二标识的对应关系确定所述第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。例如,第一终端装置从下行链路接收的数据为数据A,其混合自动重传请求进程编号,HARQ IDu=2,其中HARQ IDu代表下行链路数据对应的HARQ ID,第一终端装置在侧行链路上分别接收了数据B、数据C及数据D,其中数据B对应的UU链路关联HARQ IDs=1,数据C对应的UU链路关联HARQ IDs=2,数据D对应的UU链路关联HARQ IDs=3,其中HARQ IDs代表侧行链路数据对应的HARQ ID。数据C的HARQ IDs=2与数据A的HARQ ID相同,但是对照表2所示的对应关系,这两个 标识并不满足同一数据的下行HARQ ID与侧行HARQ ID对应关系,因此数据A与数据C并不来自自同一个数据。第一终端装置根据各个HARQ ID及表2所示的预定义的第一标识与第二标识的对应关系判断数据D(HARQ IDs=3)与数据A(HARQ IDu=2)属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,可以对这两份数据进行合并,获得合并带来的数据恢复率提升的效果。
表2第一标识与第二标识对应关系示例
第一标识 第二标识
HARQ IDu=1 HARQ IDs=1
HARQ IDu=2 HARQ IDs=3
HARQ IDu=3 HARQ IDs=2
方式C:第一标识信息包括第一标识及第二标识,第二标识信息包括所述第二标识,第一标识用于标识所述第一数据,第二标识用于标识所述第二数据。第一终端装置根据来自第一网络装置的第二标识与来自第二终端装置的第二标识确定第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。
例如,第一终端装置从下行链路接收的数据为数据A,其混合自动重传请求进程编号HARQ IDu=2,同时,其第一标识信息中还包含HARQ IDs=1,。其中HARQ IDu代表下行链路数据对应的HARQ ID,第一终端装置在侧行链路上分别接收了数据B、数据C及数据D,其中数据B对应的UU链路关联HARQ IDs=1,数据C对应的UU链路关联HARQ IDs=2,数据D对应的UU链路关联HARQ IDs=3,其中HARQ IDs代表侧行链路数据对应的HARQ ID。第一终端装置根据各个HARQ ID判断数据B(HARQ IDs=1)与数据A(HARQ IDu=2,HARQ IDs=1,)属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,可以对这两份数据进行合并,获得合并带来的数据恢复率提升的效果。
表3侧行链路接收数据及对应标识示例
数据 标识
数据B HARQ IDs=1
数据C HARQ IDs=2
数据D HARQ IDs=3
通过上述方法,第一终端装置接收来自第一网络装置的第一数据和第一标识信息以及来自第二终端装置的第二数据和第二标识信息,第一终端装置根据第一标识信息及第二标识信息确定所述第一数据与第二数据属于同一数据并将二者合并,通过对属于同一数据、来自不同链路的的数据进行合并可以提升第一终端装置从数据中成功恢复数据的概率,提升了数据传输的成功率及可靠性,这里来自同一数据是指来自同一个传输块TB、或同一个信源数据或同一个原始数据。
如图3所示,可选的,所述第一标识信息包括第一标识,所述第一标识用于标识所述第一数据,所述第二标识信息包括第二标识,所述第二标识用于标识所述第二数据,所述第二标识与所述第一标识为同一个标识;所述第一终端装置的确定单元720根据所述第一标识信息和所述第二标识信息确定所述第一数据与第二数据属于同一数据包括:所述第一终端装置的确定单元720根据所述第一标识与所述第二标识确定所述第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。可选的,第二标识是根据第一数据的第一标识确定的,所述第二标识可以与第一标识相同或通过其他方式根据第一标识确定。可选的,第二标识可以是在侧行链路上为第二数据添加的新的指示信息,隐含了第二数据是转发数据块的信息。
图3中第一数据与第一标识信息为第一网络装置在下行链路同时向第一终端装置及第二终端装置发送的,其中第一标识信息包含第一标识,第一标识用于标识第一数据。第二终端装置在下行链路上接收到来自第一网络装置的第一数据及第一标识信息,第二终端装置对第一数据进行处理后得到第二数据,第二终端装置还根据第一标识信息中的第一标识生成第二标识信息中的第二标识,第二终端装置在侧行链路上向第一终端装置发送第二数据及第二标识信息。第二数据对应的第二标识信息本身包含第一标识,因此第二标识信息中的第二标识是侧行链路上的额外指示信息,第二标识还隐含了一个含义,即这个第二数据承载的是转发的传输块,而不是非转发的传输块,即第一标识信息里的第一标识,用于标识第一数据。第二标识信息里的第一标识,用于标识第二数据本身,例如第二标识信息中的第一标识是HARQ IDss=5,该HARQ IDss与第二标识信息中的第二标识HARQ IDs无关,该HARQ IDss与第一标识信息中的第二标识HARQ IDu也无关,它的确定不依赖于第一标识信息以及第二标识信息中的任意标识,因此该第二标识信息中的第一标识不用于判断第二数据与第一数据是否对应。而第二标识信息里的第二标识是根据第一标识信息中的第一标识确定的,该第二标识信息中的第二标识用于标识该第二数据具体与哪份第一数据对应,即与哪个第一数据来自同一个传输块(Transport Block,TB)、或同一个信源数据或同一个原始数据。
例如,第一终端装置从下行链路接收的数据为第一数据,其第一标识即混合自动重传请求进程编号HARQ IDu=1,第一终端装置在侧行链路上分别接收了第二数据、第三数据,其中第二数据的第二标识UU链路关联HARQ IDs=1,第三数据的第二标识UU链路关联HARQ IDs=2。则第一终端装置根据各个HARQ ID判断第二数据与第一数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,可以对这两份数据进行合并,获得合并带来的数据恢复率提升的效果。
通过上述方法,所述第一终端装置根据来自第一网络装置的所述第一标识及来自所述第二终端装置的第二标识相同确定来自所述第一网络装置的所述第一数据及来自所述第二终端装置的所述第二数据属于同一数据,从而对所述第一数据及所述第二数据进行合并,提高了恢复所述第一数据及第二数据共同对应的传输块TB或者原始数据或者信源数据的成功率,有益于通信的可靠性。
如图4所示,可选的,所述第一标识信息包括第一标识,所述第一标识用于标识所述第一数据,所述第二标识信息包括所述第二标识,所述第二标识用于标识第二数据;图4中的第二标识与图3中的第二标识含义不同,图3中,第一标识信息里的第一标识用于标识第一数据,第二标识信息里的第二标识,用于标识和哪个第一数据对应。第二标识信息本身的第一标识用于标识第二数据(未在图3中示出)。而图4中,第二标识信息中的第二标识用于标识第二数据的同时还用于指示第一数据与第二数据 的对应关系,所以第二标识同时具备了第一标识的属性,第二标识信息中没有单独的第一标识。所述第一终端装置的确定单元720根据所述第一标识信息和所述第二标识信息确定所述第一数据与第二数据属于同一数据包括:所述第一终端装置的确定单元720根据所述第一标识与所述第二标识及所述第一标识与所述第二标识的对应关系确定所述第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。
可选的,所述第一标识与所述第二标识的对应关系为协议预定义的;或所述第一终端装置接收来自所述第一网络装置的高层信令配置或物理层信令配置,所述高层信令配置或物理层信令配置用于指示所述第一标识与所述第二标识的对应关系,所述对应关系用于指示所述第一标识所标识的所述第一数据与所述第二标识所标识的所述第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。
例如,第一终端装置从下行链路接收的第一数据,其对应的第一标识信息中的第一标识即混合自动重传请求进程编号HARQ IDu=2,第一终端装置还在侧行链路上分别接收了第二数据、第三数据及第四数据,其中第二数据对应的UU链路关联HARQ IDs=3,第三数据对应的UU链路关联HARQ IDs=2,第四数据对应的UU链路关联HARQ IDs=1。第三数据的第二标识HARQ IDs=2与第一数据的HARQ ID相同,但是对照表2所示的对应关系,这两个标识并不满足同一数据的下行HARQ ID与侧行HARQ ID对应关系,因此第一数据与第三数据并不来自自同一个数据。第一终端装置根据各个HARQ ID及表2所示的预定义的第一标识与第二标识的对应关系判断第二数据(HARQ IDs=3)与第一数据(HARQ IDu=2)属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,可以对这两份数据进行合并,获得合并带来的数据恢复率提升的效果。
所述第一标识与第二标识的对应关系的一个示例如表2所示,第一标识与第二标识的对应关系也可以表示为其他形式,本申请实施例并不限定。
通过本申请实施例,所述第一标识与所述第二标识及所述第一标识与所述第二标识的对应关系共同用于确定所述第一数据与所述第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,所述第一标识与所述第二标识的数值关系对应方式更加灵活。
如图5所示,可选的,所述第一标识信息包括第一标识及第二标识,所述第二标识信息包括所述第二标识,所述第一标识用于标识所述第一数据,所述第二标识用于标识所述第二数据,所述第二标识还用于确定所述第二数据与所述第一数据是否属于同一数据;图5中第二标识与图3中第二标识含义不用,此处第二标识信息中的第二标识用于标识第二数据的同时还用于指示第一数据与第二数据的对应关系,所以第二标识同时具备了第一标识的属性,第二标识信息中没有单独的第一标识。所述第一终端装置根据所述第一标识信息和所述第二标识信息确定所述第一数据与第二数据属于同一数据包括:所述第一终端装置根据来自所述第一网络装置的所述第二标识与来自所述第二终端装置的所述第二标识确定所述第一数据与第二数据属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。
图5中第一终端装置从下行链路接收的数据为第一数据,其对应的第一标识信息即混合自动重传请求进程编号HARQ IDu=2,同时,其第一标识信息中还包含HARQ IDs=1, 该HARQ IDs为该第一标识信息中的第二标识。第一终端装置在侧行链路上分别接收了第二数据、第三数据及第四数据,其中第二数据对应的第二标识UU链路关联HARQ IDs=1,第三数据对应的第二标识UU链路关联HARQ IDs=2,数据D对应的第二标识UU链路关联HARQ IDs=3,其中HARQ IDs代表侧行链路数据对应的HARQ ID。第一终端装置根据各个HARQ ID判断第二数据(HARQ IDs=1)与第一数据(HARQ IDu=2,HARQ IDs=1,)属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据,可以对这两份数据进行合并,获得合并带来的数据恢复率提升的效果。
可选的,第一标识可以为混合自动重传请求(Hybrid Automatic Repeat Request,HARQ)进程编号,该HARQ进程编号为网络配置的或其他方式确定的。可选的,第一标识信息及第二标识信息还可以包括新数据指示NDI和/或子载波编号CARRIER ID和/或小区编号CELL ID。
可选的,对于HARQ进程编号相同的相邻两次传输,若其NDI没有变化,则这两次传输的数据信号来自同一个传输块。如果HARQ进程编号相同的相邻两次传输的NDI有变化,则说明这两次传输的数据信号来自不同的传输块或不同的原始数据或不同的信源数据。
可选的,在两个不同的子载波上分别传输的两个数据可以有两个完全一样的HARQ进程编号,但这两个HARQ进程编号对应的数据是完全不同的,并不来自同一个数据,因此在确定数据是否来自同一数据时,可能还需要子载波编号CARRIER ID,例如,若两份数据数据来自不同的子载波,则无论第一标识与第二标识是否相同或是否满足对应关系,该来自不同子载波的两份或多份数据都不能合并。
可选的,还可以结合小区编号CELL ID共同判断不同链路的数据是否属于同一数据,第一数据和第二数据属于同一数据是指第一数据和第二数据来自同一个传输块TB、或同一个信源数据或同一个原始数据。
可选的,第一数据与第二数据属于同一数据包括:所述第一数据与第二数据属于同一数据块或来自相同的信源数据或来自相同的原始数据,第一数据与第二数据是经过这些相同的数据块或信源数据或原始数据经过编码得到的。
如图6所示的示例,第一标识信息及第二标识信息同时包含HARQ进程编号及新数据指示NDI。第一终端装置接收来自下行链路的第一数据及第一标识信息,其中第一标识信息的第一标识HARQID=1,第一终端装置在侧行链路上接收第五数据、第四数据、第三数据、第二数据以及它们的分别对应的标识信息。第一终端装置收到下行链路上和侧行链路的数据信号后,在满足时间规则的条件下,在侧行链路收到HARQ ID对应的侧行数据信号,便知道这个来自第一网络装置的数据信号和这个侧行数据信号来自相同的传输块,可以对他们进行合并。时间规则可以是,收到上述下行链路数据信号后的delta_T个时间单位之后的第一个HARQ IDs对应的新传侧行数据信号。
图6中,侧行数据与下行数据是否来自同一传输块或信源数据的判断方式为:当下行数据的标识信息与侧行数据的标识信息相同代表两份数据来自同一传输块或信源数据。第一终端装置在下行链路上接收来自第一网络装置的第一数据及第一标识信息,其中第一标识信息的第一标识HARQ ID=1。第一终端装置在侧行链路上接收第二至第五数据及对应的标识信息。其中,第五数据及第四数的接收与下行链路第一数据的接 收之间的时间差小于Δt,其中Δt代表解码延迟,即第一数据为第一网络装置同时发送给第一终端装置及第二终端装置的,第一终端装置接收到第一数据后Δt时间后从侧行链路上接收的数据才有可能是第二终端装置接收到第一数据后发送的第二数据,Δt为预留的第二终端装置解码的时间。因此第五数据与第四数据虽然HARQ ID=1,但是这两份数据不满足时间条件,因此这两份数据与第一数据不属于同一个传输块或信源数据。第三数据的标识信息与第四标识信息相同,因此第三数据与第一数据也不来自同一数据,第二数据的HARQ ID=1、NDI=0,代表是与第三数据不同的新数据,且接收时间符合条件,因此第二数据与第一数据来自同一数据,如图6中阴影部分所示,可以进行合并。可选的,时间关系,除了所述的delta_t,还可以是指定的侧行发送时间单位,例如在PDCCH信道的最后一个符号后的第X个符号开始的侧行传输。上述的PDSCH信道的最后一个符号、PDCCH的最后一个符号,都是确定时间关系的起始点位置的例子。本发明不排除通过其他方式确定时间关系的起始点。
可选的,根据所述第一标识信息和所述第二标识信息确定所述第一数据与第二数据属于同一数据还包括:所述第一终端装置根据所述第一标识信息、所述第二标识信息、第一时间差值以及第一时间阈值确定所述第一数据与第二数据属于同一数据,所述第一时间差值包括所述第一终端装置接收所述第一数据的时间与所述第一终端装置接收所述第二数据的时间的时间差值,所述第一时间差值小于所述第一时间阈值;所述第一时间阈值为协议预定义的,或所述第一终端装置接收来自所述第一网络装置的高层信令配置或物理层信令配置,所述高层信令配置或物理层信令配置用于指示所述第一时间阈值。
可选的,为了避免发生网络设备动态分配的侧行HARQ ID已经被侧行自行使用的冲突情况,网络设备可以预先给侧行可使用的侧行HARQ ID配置侧行HARQ ID资源池,侧行HARQ ID资源池中的侧行HARQ ID,都是用作转发传输块使用的。这样,网络设备动态分配的侧行HARQ ID,都来自这个资源池,这样可以避免网络设备动态分配的侧行HARQ ID会被侧行自行使用的冲突情况。例如,HARQ IDs的取值只有为1、2、3、4中的一个时,才代表其对应的数据是第二终端装置转发给第一终端装置并需要寻找下行链路上来自相同数据或数据块的某一数据并完成合并操作。如果HARQ IDs取值为其他,例如取值为HARQ IDs=6,则代表其对应的数据并不是转发的,不需要进行合并操作。
可选的,还可以通过额外的指示来辅助第一终端装置区分这个数据信号承载的是转发的传输块还是非转发的传输块。当指示为转发的传输块时,第一终端装置才将下行链路上的HARQ ID和侧行链路上的HARQ ID对应的数据信号查找关联关系。额外的指示比如显示的1比特flag,1代表是转发的,0代表是非转发的。
可选的,第一终端装置与所述第二终端装置同属于一个协作组,所述协作组中的终端装置数量大于等于2。通过本方法,所述协作组除所述第一终端装置及所述第二终端装置外,还可以包含第三终端装置或更多终端装置,其中第三终端装置具有第二终端装置或第一终端装置相同的功能。众多终端装置互相协作,可有效提升每个终端装置恢复数据的成功率。
