Description

数据传输方法和设备 技术领域
本发明实施例涉及通信技术领域,尤其涉及一种数据传输方法和设备。
背景技术
在通用移动通信系统(英文:Universal Mobile Telecommunications System,简称:UMTS)中,网络在发送数据时通常是以传输时间间隔(英文:Transmission Time Interval,简称:TTI)为单位进行发送,通常网络在发送数据包时会尽可能以较高的功率发送,确保UE可以在一次发送中就接收到该数据包。对于用户设备(英文:User Equipment,简称:UE)在接收网络设备发送的一些第二信道之前,通常该UE还会接收网络设备发送的第一信道,根据该第一信道中携带的信息来确定是否需要在预定的时间之后接收对应的第二信道的数据。例如:UE首先要解析寻呼指示信道(英文:Page Indicator Channel,简称:PICH),再根据PICH中的寻呼指示(英文:Page Indicator,简称:PI)确定是否需要在接收完PICH之后间隔预定的时间接收辅公共控制物理信道(英文:Secondary Common Control Physical Channel,简称:S-CCPCH)或者高速物理下行共享控制信道(英文:High Speed Physical Downlink Shared Control Channel,简称:HS-SCCH)的内容。或者,UE首先需要解析HS-SCCH,再根据HS-SCCH信道携带的高速物理下行链路共享信道无线网络临时标识(英文:High-Speed Downlink Shared Channel RNTI,简称:H-RNTI)确定是否需要在开始接收所述HS-SCCH之后间隔预定的时间接收高速物理下行共享信道(英文:High Speed Physical Downlink Shared Channel,简称:HS-PDSCH)。
然而,网络设备为了在较低发送功率的状态下增强覆盖,会采用重复发送的方式,将相同的内容重复发送N次(N>=2),确保处于覆盖较差区域内的UE可以正确接收数据。在采用重复发送的方式时,如果UE仍然按照上述的预定时间或处理方式进行第一信道和第二信道的数据的接收,可能会导致UE无法正确的获取到数据,导致数据的丢失。

图5为本发明数据传输方法实施例一的流程图,如图5所示。
S101、UE接收M次网络设备通过第一信道发送的第一数据,M为小于或等于第一数据重复传输次数N的正整数,N为大于或等于2的整数。
S102、所述UE解析所接收的M次的所述第一数据,获得所述第一数据的解析结果。
S103、当第一数据的解析结果指示所述UE处理所述网络设备通过第二信道发送的第二数据时,所述UE处理所述第二数据。
本实施例中,所述网络设备可以为BSC、RNC、NodeB、eNB、ASN BS等,所述第一信道不同于所述第二信道,且所述第一信道和所述第二信道可以为任何信道,例如物理信道或控制信道,例如分别为PICH、S-CCPCH、HS-SCCH、HS-PDSCH等中的任意两种。
本实施例中,网络设备为了增强覆盖,采用重复发送的方式,将相同的内容重复发送多次,以确保处于覆盖区域内的UE均可以正确接收。由于各种原因,例如不同覆盖区域的信号质量不同,UE接收数据的次数可以小于等于网络设备发送该数据的次数。例如,网络设备可以通过第一信道向UE发送N次第一数据,此处第一数据为通过第一信道传输的数据,相应地,UE也会接收M次该网络设备通过第一信道发送的第一数据(M<=N),其中M为小于或等于第一数据重复传输次数N的正整数,N为大于或等于2的整数。
由于各个UE所处的该网络设备的覆盖区域不同,有些UE处于覆盖较好的区域(例如信号质量大于等于第一阈值),而有些UE处于覆盖较差的区域(例如信号质量小于第一阈值),处于覆盖较好的区域中的UE接收第一数据的次数可以小于处于覆盖较差的区域中的UE接收第一数据的次数,所以各个覆盖区域的不同UE接收该第一数据的次数M不同。M的取值以该UE完全解析出第一数据所根据的第一数据的个数为基准来确定,例如:若网络设备通过第一信道向UE发送6次第一数据,若UE根据接收的3次第一数 据就可以解析出第一数据,则该M为大于或等于3,并且,小于或等于6的整数。较简单的,所有的UE均接收N次第一数据。其中,该网络设备通过第一信道发送第一数据的方式可以如图6和如图7所示,在图6所示的第一数据发送方式中,网络设备通过第一信道向UE连续发送N次第一数据,相应地,UE可以连续接收M次第一数据。在图7所示的第一数据的发送方式中,网络设备通过第一信道向UE发送完一次第一数据时,间隔一定的时间开始发送下一次第一数据,相应地,UE在接收完一次第一数据时,间隔一定的时间可以接收到下一次第一数据。图7中每次重复发送第一数据的时间间隔可以不同,也可以相同,在此不做限制。
其中,所述UE解析所接收的M次的所述第一数据,获得所述第一数据的解析结果,可以包括:UE可以对所接收的M次的第一数据一起合并后进行解析,从而可以获得正确的第一数据的解析结果。或者,所述UE对第一次接收的所述第一数据进行解析,解析不到结果后,将第一次接收的第一数据与第二次接收的第一数据合并后进行解析,仍然解析不到结果后,将第一次、第二次、…、第M次接收的第一数据合并后进行解析,直至可以获取正确的第一数据的解析结果。
无论采用上述哪一种方式获得第一数据的解析结果,UE均是获得所接收的M次的第一数据的解析结果后,再根据该解析结果来确定是否对第二数据进行处理,当第一数据的解析结果指示UE处理该第二数据时,UE处理该第二数据;当第一数据的解析结果指示UE不处理该第二数据时,UE不处理该第二数据,此处第二数据为通过第二信道传输的数据。具体地,UE可以根据该解析结果来确定是否接收第二数据,即当所述第一数据的解析结果指示所述UE接收所述第二数据时,所述UE接收K次所述第二数据,K为小于或等于第二数据重复次数H的正整数,当所述第一数据的解析结果指示所述UE不接收所述第二数据时,所述UE不接收所述第二数据;或者,UE可以根据该解析结果来确定是否解析第二数据,即当所述第一数据的解析结果指示所述UE解析所述第二数据时,所述UE解析所接收的K次的所述第二数据,当所述第一数据的解析结果指示所述UE不解析所述第二数据时,所述UE可以丢弃接收的所述第二数据。由于该解析结果是根据多个第一数据获得的,从而可以保证正确的获得第一数据的解析结果,并且保证第二数据的正确获 取,避免了第二数据的丢失。
现有技术中,UE是每次接收完第一数据后立即对该第一数据进行解析,再根据第一数据的解析结果确定是否间隔预设时间对第二数据进行处理,当UE处于覆盖较差的区域时,UE可能无法正确接收或者解析所接收的第一数据,会将接收或解析第二数据的指示丢失,从而使得UE不能在间隔预设时间正确的获得第二数据,造成第二数据的丢失。
而本实施例,通过UE接收M次网络设备通过第一信道发送的第一数据,并根据所接收的M次的所述第一数据,获得所述第一数据的解析结果,以及当所述第一数据的解析结果指示所述UE处理第二数据时,所述UE处理所述网络设备通过第二信道发送的第二数据,由于该解析结果是根据所接收的M次的第一数据解析获得的,从而可以保证正确的获得第一数据的解析结果,并保证第二数据的正确获取,避免了第二数据的丢失。
在本发明实施例中,所述的解析是指对接收到的数据进行解调、译码或者相关等物理层的一个或者多个过程,并获取到所述数据内容的过程。例如:针对PICH信道,解析之后就可以获得该UE对应的PI值,针对HS-SCCH信道,解析之后就可以获得HS-SCCH包含的H-RNTI,UE根据该H-RNTI获得后续的HS-PDSCH信道所承载的数据是否针对该UE发送的。
在本发明实施例中,所述的数据可以指UE物理层接收到的,未经过物理层处理的或者经过物理层部分处理的信号,也可以是指物理层已经处理完成向高层递交的数据单元。
图8为本发明数据传输方法实施例二的流程图,如图8所示。
S201、网络设备通过第一信道向UE发送第一数据重复次数N次第一数据,所述N为大于或等于2的整数。
S202、所述网络设备在需要向UE发送第二数据时,通过第二信道向所述UE发送第二数据重复次数H次所述第二数据,所述H为大于或等于2的整数。
本实施例中,网络设备为了增强覆盖,会采用重复发送的方式,将相同的内容重复发送多次,以确保处于覆盖区域内的UE均可以正确接收。网络设备可以通过第一信道向UE发送N次第一数据,以及在网络设备需要向UE发送第二数据时,通过第二信道向UE发送H次第二数据;需要说明的是, S202可以在S201执行完之后执行,S202也可以在S201的执行过程中执行,本发明实施例对此不做限定。其中,该网络设备发送第一数据的方式可以如图6和如图7所示,在图6所示的第一数据发送方式中,网络设备通过第一信道向UE连续发送N次第一数据;在图7所示的第一数据的发送方式中,网络设备通过第一信道向UE发送完一次第一数据时,间隔一定的时间开始发送下一次第一数据。图7中每次重复发送第一数据的时间间隔可以不同,也可以相同,在此不做限制。需要说明的是,该网络设备发送第二数据的方式可以与发送第一数据的方式类似,此处不再赘述。其中H和N可以相同,也可以不同。
相应地,UE接收M次网络设备通过第一信道发送的第一数据,解析接收M次(M<=N)的所述第一数据,获得所述第一数据的解析结果,以及当所述第一数据的解析结果指示所述UE处理网络设备通过第二信道发送的第二数据时,处理所述第二数据。具体实现过程可以参见本发明方法实施例一中的相关记载,此处不再赘述。由于该解析结果是根据多个第一数据获得的,从而可以保证正确的获得第一数据的解析结果,并且保证第二数据的正确获取,避免了第二数据的丢失。在本发明实施例中,所述的解析是指对接收到的数据进行解调、译码或者相关等物理层的一个或者多个过程,并获取到所述数据内容的过程。
本实施例,网络设备通过第一信道向UE发送N次第一数据,以及在需要向UE发送第二数据时,通过第二信道向所述UE发送H次第二数据,从而使得UE接收M次网络设备通过第一信道发送的第一数据(M<=N),并解析所接收的M次的所述第一数据,获得所述第一数据的解析结果,以及当所述第一数据的解析结果指示所述UE处理所述网络设备通过第二信道发送的第二数据时,处理所述第二数据,由于该解析结果是根据所接收的M次的第一数据解析获得的,可以保证第一数据的正确解析,从而可以保证第二数据的正确获取,避免了第二数据的丢失。
图9为本发明数据传输方法实施例三的流程图,如图9所示。
S301、网络设备向UE发送第一数据重复传输次数N和第二数据重复传输次数H,其中,N和H分别为大于或等于2的整数。
本实施例中,网络设备可以向UE发送各个数据的重复传输次数,例如 网络设备可以向UE发送第一数据重复传输次数N和第二数据重复传输次数H。通过第一信道传输的数据称为第一数据,通过第二信道传输的数据称为第二数据为,N和H可以相同,也可以不同。如果第一信道的重复传输次数和第二信道的重复传输次数相同,则网络设备仅需要发送一个值即可,不需区分第一信道和第二信道;所述网络设备也可以分别针对所述第一信道和第二信道发两个相同值。
S302、网络设备通过第一信道向所述UE发送N次第一数据。
S303、所述UE接收M次网络设备通过第一信道发送的第一数据,其中M为正整数且M<=N。

S306、当所述第一数据的解析结果指示所述UE接收所述第二数据时,所述UE在开始第一次接收所述第一数据时,间隔第一时间开始接收K次所述第二数据。
在本实施例的第一种可行的实现方式中,上述第一时间为传输N次第一数据所需的时间与预设时间之和的时间,当所述网络设备需要向所述UE发送第二数据时,该网络设备在通过第一信道向UE开始发送第一次第一数据时,间隔发送N次第一数据所需的时间与预设时间之和的时间开始通过第二信道向UE发送H次第二数据。相应地,当第一数据的解析结果指示该UE接收第二数据时,UE需要等到网络设备发送完第二数据时,即网络发送完N次第一数据后才可以开始接收第二数据,由于UE每次接收第一数据所需的时间可以确定,因此,UE可以在开始第一次接收第一数据时,间隔接收N次第一数据所需的时间和预设时间之和的时间开始接收第二数据,并且接收 K次第二数据,其中,K为小于或等于H的正整数。上述过程可以如图6所示,图10仅示出了在图6所示的发送方式下的第一信道与第二信道的定时关系,在图7所示的发送方式下也类似,此处不再赘述。对于K小于或等于H,可以参见本发明方法实施例一中M小于或等于N的相关记载,此处不再赘述。所述预设时间是指UE可以正确解析(或者处理)所接收的第一数据的时间。例如,当第一信道为PICH,第二信道为S-CCPCH时,该预设时间为τPICH,UE通过τPICH的时间,可以获得第一数据中的PI信息,τPICH可以为现有技术中网络设备发送完PICH与开始发送S-CCPCH的时间间隔。若第一信道为PICH,第二信道为HS-SCCH,则预设时间可以为一个子帧,即2ms,如UE可以通过2ms,获得第一数据中的PI信息。
在本实施例的第二种可行的实现方式中,上述第一时间可以为传输N-1次所述第一数据所需的时间与预设时间之和的时间。当网络设备需要向UE发送第二数据时,该网络设备在通过所述第一信道向所述UE开始发送第一次所述第一数据时,间隔发送N-1次第一数据所需的时间与预设时间之和的时间开始通过所述第二信道向所述UE发送H次所述第二数据。相应地,当第一数据的解析结果指示该UE接收第二数据时,由于UE每次接收第一数据所需的时间可以确定,因此,UE可以在开始第一次接收第一数据时,间隔接收N-1次第一数据所需的时间和预设时间之和的时间开始接收第二数据,并且接收K次第二数据。如图11所示,图11仅示出了在图6所示的发送方式下的第一信道与第二信道的定时关系,在图7所示的发送方式下也类似,此处不再赘述。所述预设时间是指UE可以正确解析(或者处理)所接收的第一数据的时间。例如:当第一信道为HS-SCCH,第二信道为HS-PDSCH时,所述预设时间为τHS-PDSCH,当网络设备通过HS-SCCH发送一次第一数据所需时间为3个时隙,即7680个码片,网络设备通过HS-PDSCH发送一次第二数据所需时间为3个时隙,即7680个码片,τHS-PDSCH为2个时隙,即τHS-PDSCH为5120个码片,UE通过该预设时间可以获得第一数据中的H-RNTI,也可以获得HS-SCCH中包含后续的HS-PDSCH的解码信息。
进一步地,在UE接收完K次第二数据后,还可以解析该K次第二数据获得第二数据的解析结果,具体过程可以参见本发明方法实施例一中UE解析M次第一数据获得第一数据的解析结果中的相关记载,此处不再赘述。
当第一数据的解析结果指示该UE不接收第二数据时,UE不接收第二数据。
在本发明实施例中,所述的解析是指对接收到的数据进行解调、译码或者相关等物理层的一个或者多个过程,并获取到所述数据内容的过程。
本实施例,通过网络设备向UE发送第一数据重复传输次数N和第二数据重复传输次数H,然后网络设备通过第一信道向UE发送N次第一数据,并在向所述UE开始发送第一次所述第一数据时,间隔发送N次第一数据所需时间与预设时间之和的时间,或者,发送N-1次第一数据所需时间与预设时间之和的时间,通过所述第二信道向所述UE发送H次所述第二数据;UE接收M次所述第一数据,解析所接收的M次的所述第一数据,获得所述第一数据的解析结果,当所述第一数据的解析结果指示所述UE接收所述第二数据时,所述UE在开始第一次接收所述第一数据时,间隔接收N次第一数据所需时间与预设时间之和的时间,或者,接收N-1次第一数据所需时间与预设时间之和的时间,开始接收K次所述第二数据。由于该解析结果是根据所接收的M次的第一数据解析获得的,从而可以保证第一数据的正确的解析,并根据第一数据的指示在预定的时间开始接收第二数据,保证第二数据的正确获取,避免了第二数据的丢失;同时实现了在重复发送时第一信道与第二信道的定时关系。
图12为本发明数据传输方法实施例四的流程图,如图12所示,本实施例的方法可以包括:
S401、网络设备向UE发送第一数据重复传输次数N和第二数据重复传输次数H,其中,N和H分别为大于或等于2的整数。
S402、网络设备通过第一信道向所述UE发送N次第一数据。
S403、所述UE接收M次网络设备通过第一信道发送的第一数据,其中M为正整数且M<=N。
S404、所述UE解析所接收的M次的所述第一数据,获得所述第一数据的解析结果。
本实施例中,S401-S404的具体实现过程与本发明方法实施例三中的S301-S304的具体实现过程类似,此处不再赘述。需要说明的是,S404在S407之前执行即可,在此对S404与S405、S406的执行顺序不做限制。
S405、当所述网络设备需要向所述UE发送第二数据时,所述网络设备在通过所述第一信道向所述UE开始发送第一次所述第一数据时,间隔第一时间开始通过所述第二信道向所述UE发送H次所述第二数据。
S406、所述UE在第一次接收完所述第一数据时,间隔第一时间开始接收K次所述第二数据。
在本实施例的第一种可行的实现方式中,上述第一时间为传输一次第一数据的时间(例如一个TTI的时间或者一个子帧的时间)和预设时间之和的时间,当所述网络设备需要向所述UE发送第二数据时,该网络设备在通过第一信道向UE开始发送第一次第一数据时,间隔发送一次第一数据所需的时间与预设时间之和的时间开始通过第二信道向UE发送H次第二数据。相应地,UE可以在开始第一次接收第一数据时,间隔接收一次第一数据所需的时间和预设时间之和的时间开始接收第二数据,并且接收K次第二数据,其中,K为小于或等于H的正整数。上述过程可以如图13所示,图13仅示出了在图6所示的发送方式下第一信道与第二信道的定时关系,在图7所示的发送方式下也类似,此处不再赘述。所述预设时间是指UE可以正确解析(或者处理)所接收的第一数据的时间。例如,当第一信道为PICH,第二信道为S-CCPCH时,该预设时间为τPICH,UE通过τPICH的时间,可以获得第一数据中的PI信息,τPICH可以为现有技术中网络设备发送完PICH与开始发送S-CCPCH的时间间隔。当第一信道为PICH,第二信道为HS-SCCH时,该预设时间可以为一个子帧,例如2ms,如UE可以通过2ms,获得第一数据中的PI信息。
在本实施例的第二种可行的实现方式中,上述第一时间为预设时间,如图14所示,当所述网络设备需要向所述UE发送第二数据时,该网络设备在通过第一信道向UE开始发送第一次第一数据时,间隔预设时间开始通过第二信道向UE发送H次第二数据。相应地,UE可以在开始第一次接收第一数据时,间隔预设时间开始接收第二数据,并且接收K次第二数据。上述过程可以如图14所示,图14仅示出了在图6所示的发送方式下第一信道与第二信道的定时关系,在图7所示的发送方式下也类似,此处不再赘述。所述预设时间是指UE可以正确解析(或者处理)所接收的第一数据的时间。例如:当第一信道为HS-SCCH,第二信道为HS-PDSCH时,该预设时间为τHS-PDSCH, 当网络设备通过HS-SCCH发送一次第一数据所需时间为3个时隙,即7680个码片,网络设备通过HS-PDSCH发送一次第二数据所需时间为3个时隙,即7680个码片,τHS-PDSCH为2个时隙,即τHS-PDSCH为5120个码片,UE通过该预设时间可以获得第一数据中的H-RNTI,也可以获得HS-SCCH中包含的后续的HS-PDSCH的解码信息。
需要说明的是,S406在执行S403的过程中执行,即存在第二数据和第一数据同时接收的情况。
S407、当所述第一数据的解析结果指示所述UE解析所述第二数据时,所述UE解析所接收的K次的所述第二数据。
可选地,第一数据的解析结果也可以指示所述UE接收所述第二数据,由于UE在没有得到第一数据的解析结果时就已经接收了第二数据,因此该接收指示可以等同于解析指示,即UE对已经接收到的第二数据进行解析处理。
可选地,当第一数据的解析结果指示该UE不解析第二数据时,UE丢弃接收的第二数据。可选地,第一数据的解析结果也可以指示UE不接收第二数据,由于UE已经接收了部分第二数据,此时UE可以将接收的数据丢弃。
在本发明实施例中,所述的解析是指对接收到的数据进行解调、译码或者相关等物理层的一个或者多个过程,并获取到所述数据内容的过程。
本实施例,通过网络设备向UE发送第一数据重复传输次数N和第二数据重复传输次数H,然后网络设备通过第一信道向UE发送N次第一数据,在向所述UE开始发送第一次所述第一数据时,间隔发送一次第一数据所需时间与预设时间之和的时间,或者,预设时间,开始通过所述第二信道向所述UE发送H次所述第二数据;UE接收M次所述第一数据,解析所接收的M次的所述第一数据,获得所述第一数据的解析结果,同时,在第一次开始接收第一数据时,间隔接收一次第一数据所需时间与预设时间之和的时间,或者,预设时间开始接收K次所述第二数据,当所述第一数据的解析结果指示所述UE解析所述第二数据时,所述UE解析所接收的K次的所述第二数据。由于该解析结果是通过解析所接收的M次的第一数据获得的,从而可以保证第一数据解析的正确性,根据所述解析结果,可以保证第二数据的正确获取,避免了第二数据的丢失;同时实现了在重复发送时第一信道与第二信 道的定时关系。
本实施例,也可以包含UE同时接收第一信道和第二信道的场景,在该方式中,网络设备可以同时发送针对该UE的第一数据和第二数据。UE根据第一数据的解析结果,确定后续对第二信道的处理。可选地,UE也可以只接收第二信道,不接收第一信道。即:网络不发送第一信道,只通过第二信道发送第二数据。
在本发明上述方法实施例的基础上,可选地,所述第一信道为PICH,所述网络设备根据第一数据重复传输次数N,通过第一信道向所述UE发送N次第一数据之前,还包括:所述网络设备向所述UE发送寻呼时机的获取参数。所述UE接收所述网络设备发送的寻呼时机的获取参数后,可以根据所述寻呼时机的获取参数,获取所述寻呼时机;并且当所述寻呼时机到达时,所述UE开始接收M次所述网络设备通过所述第一信道发送的所述第一数据。可选地,网络设备可以在向UE发送第一数据重复次数N和第二数据重复次数H的同时,向UE发送寻呼时机的获取参数。
