Description

数据时域传输方法及控制方法、终端、基站和基带芯片
本申请要求于2017年02月27日提交中国专利局、申请号为201710108734.5、发明名称为“数据时域传输方法及控制方法、终端、基站和基带芯片”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
本申请涉及通信技术领域,尤其涉及一种数据时域传输方法及控制方法、终端、基站和基带芯片。
背景技术
MulteFire技术是一种将LTE(Long Term Evolution,长期演进)扩展到非授权频段的无线接入技术,该技术中,非授权频段载波可以不借助授权频段载波独立提供服务。
目前,为使多个非授权频段设备(如Wi-Fi设备)公平占用非授权频段信道,并避免非授权频段设备之间的相互干扰,在MF(MulteFire)物理层引入类似Wi-Fi的载波监听技术的LBT(Listen Before Talk,先听后说)机制,在基站或终端监听到非授权频段信道被占用时,即LBT失败时,不得发送信号,当监听到非授权频段信道空闲时,即LBT成功时,才发送信号。
然而,由于对于位于一些特殊地理位置的非授权频段设备,例如,位于地下室里的水表和电表等,因该种地理位置的信道衰落比较大,信号的穿透损失也比较大,故需要通过对各个物理信道进行CE(Coverage Enhancement,覆盖增强),来实现信号质量的增强或传输距离的扩大。
相关技术中,对于第一代至第四代移动通信系统,因其在授权频段上,信道是永远可用的。而对于使用MulteFire技术的移动通 信系统,因多个非授权频段设备需共存在于LBT机制下工作,单个非授权频段设备每次接入信道后的MCOT(Maximum Channel Occupancy Time,最大信道占用时间)受到LBT机制的影响,信道对于该非授权频段设备并不永远可用的,例如,目前Multefire设备的最长信道占用时间不可超过10ms,如果非授权频段设备在自身的信道占用时间内未完成重复性传输,则很可能导致数据传输失败,影响通信功能。
因此,如何强化通信设备在非授权频段进行数据的覆盖增强,并提高传输的成功率,成为目前亟待解决的技术问题。

如图1所示,本申请的一个实施例的数据时域传输方法,用于在非授权频段传输数据,包括:
步骤102,在当前信道占用时间内,获取基站发布的续传调度 信息。
该续传调度信息为指示终端在当前信道占用时间内何时、何种方式进行重复性的数据续传的信息,而其中的数据续传则指的是终端向基站上传数据和/或基站向终端下发数据,当然,数据续传还可以是两个终端之间进行的数据交互。
故在通过物理上行共享信道或物理下行共享信道进行数据传输的过程中,如果基站检测到在前的信道占用时间内具有未完成的数据传输,可发布续传调度信息,供终端使用,也就是说,无论数据续传的双方为谁,控制数据续传过程、发布续传调度信息的都是基站。
步骤104,根据续传调度信息,在当前信道占用时间内进行数据续传。
当终端检测到该续传调度信息时,即可根据该续传调度信息的指示内容在当前信道占用时间内进行数据续传。这样,可以避免因在单个信道占用时间内未完成数据的重复性传输而导致的数据传输失败的情况,实现了在非授权频段跨多个信道占用时间的数据续传,增加了通信的可靠性,提升了用户体验。
下面通过实施例二对实施例一进行补充和细化描述。
实施例二
图2示出了本申请的另一个实施例的数据时域传输方法的流程图。
如图2所示,本申请的另一个实施例的数据时域传输方法,用于在非授权频段传输数据,包括:
步骤202,检测基站侧当前信道占用时间的开始时间点。也就是获取基站开始占有当前信道的时间点。
步骤204,检测在前信道占用时间内数据停止传输的时间点与当前信道占用时间的开始时间点的间隔时长。
其中,数据停止传输的时间点可以为在前信道占用时间内的任一点,也可以是在前信道占用时间的结束时间点,这样,可以精确 地计算出数据停止传输时到当前信道占用时间开始时的间隔时长,由于该间隔时长为进一步判断是否需要检测基站发布的续传调度信息的依据,因此,精确计算该间隔时长,可以提升后续步骤的准确性。
在一些情况下,为了提升上述检测步骤的便利性,也可以直接计算在前信道占用时间的结束时间点与当前信道占用时间的开始时间点的间隔时长,作为进一步判断的依据。
步骤206,根据间隔时长,判断是否需要检测基站发布的续传调度信息,当判断结果为是时,进入步骤208,当判断结果为否时,结束进程。
其中,在间隔时长小于或等于预定时长的情况下,判断结果为需要检测基站发布的续传调度信息。
预定时长是由基站配置的、并且由多用户共享或为单个用户特定的一个高层信令,比如,RRC(Radio Resource Control,无线资源控制协议)信令。一般来说,可将预定时长理解为在前信道占用时间的数据传输中断后能够在当前信道占用时间内成功续传数据的最低间隔时长,因此,可将实际间隔时长与预定时长进行比较,以确定是否还有可能成功进行数据续传。
在间隔时长小于或等于预定时长的情况下,间隔时长未超过能够在当前信道占用时间内成功续传数据的最低间隔时长,说明仍有可能成功进行数据续传,此时,即可进入步骤208,检测是否能够获取到基站发布的续传调度信息,以判断当前信道占用时间内是否有数据续传。
在判断结果为间隔时长大于预定时长的情况下,则终端就不必去检测能否获取到基站发布的续传调度信息了。也就是说,如果实际的间隔时长大于预定时长,说明重复性数据传输的中断时间过久,无法进行续传或没有必要进行续传。
步骤208,检测基站发布的续传调度信息,其中,当检测到基站发布的续传调度信息时,进入步骤210,当未检测到基站发布的 续传调度信息时,可以直接结束进程。或者,图2中未示出的是,在特定的一段时间内持续检测,若一直检测不到,再结束进程。
步骤210,在当前信道占用时间内,获取基站发布的续传调度信息。
步骤212,根据续传调度信息,确定当前信道占用时间内的第一时间点和重复传输次数。
步骤214,按照重复传输次数,从第一时间点开始进行数据续传。
其中,第一时间点是当前信道占用时间内开始数据续传的时间点,而重复传输次数则包括时域重复传输次数和频域重复传输次数,指示了进行数据续传所需的时频资源。
下面结合图3和图4来描述根据续传调度信息,确定当前信道占用时间内的第一时间点的一种实现方式。
如图3所示,计算第一时间点的步骤包括:
步骤302,检测续传调度信息是否携带有用于发送续传调度信息的时间窗口的结束时间点,当检测结果为是时,进入步骤304,当检测结果为否时,进入步骤306。
步骤304,从续传调度信息中获取结束时间点。
由于基站是在一个特定的时间窗口发送续传调度信息的,因此,续传调度信息内可直接记录有该时间窗口的结束时间点。
步骤306,获取预先定义的时间窗口的长度,并检测当前信道占用时间的开始时间点。
步骤308,将开始时间点和时间窗口的长度相加,得到时间窗口的结束时间点。
需要知晓,该时间窗口可以开始于当前信道占用时间的起始点,也可以开始于当前信道占用时间的第三时间点。进一步的,该时间窗口的长度是预先定义的,或者基站配置的,或者用户通过基站配置的时间窗口结束时所在的子帧索引,推导出该时间窗口的长度。
在步骤306和308中,时间窗口的长度的预先定义的,因此,终端也可以检测当前信道占用时间的开始时间点,并与预先定义的时间窗口的长度相加,来计算得到时间窗口的结束时间点。
步骤310,获取结束时间点与第一时间点的时间间隔。
步骤312,将结束时间点与时间间隔相加,得到第一时间点。
该时间间隔指的是时间窗口结束时间点后能够进行数据续传所需要间隔的时间,即
Figure PCTCN2018076046-appb-000001
其中,
Figure PCTCN2018076046-appb-000002
为发送续传调度信息的时间窗口结束时所在子帧索引,即时间窗口的结束时间点,k为该子帧索引与第一时间点的时间间隔,k≥0,
Figure PCTCN2018076046-appb-000003
为第一时间点,也就是重复性数据续传开始的子帧索引。这里该时间间隔可以是预先定义的,也可以是在动态的续传调度信息内发送的。
例如,当k的取值为0时,在时间窗口结束的TTI(Transmission Time Interval,传输时间间隔)内开始发送重复性的续传数据。
再例如,如图4所示,在前信道占用时间211具有未完成的重复性数据传输,当终端检测到基站在当前信道占用时间的时间窗口221进行了续传调度信息的发送时,获取该续传调度信息,其中,标注为A的TTI为时间窗口221内发送续传调度信息的时间点,当检测到续传调度信息中k=1时,可以在时间窗口221结束的子帧索引后第一个TTI,也就是图4中标注为B的TTI,开始重复性的数据续传,其中,重复性数据传输进行的时长如时间窗口231所示。
实施例三
在图2示出的实施例的基础上,根据续传调度信息,确定当前信道占用时间内的第一时间点的步骤,还可以有结合图5和图6示出的另一种实现方式。
如图5所示,包括:
步骤502,确定终端检测到所述续传调度信息的第二时间点, 和所述第二时间点与所述第一时间点的时间间隔。
步骤504,将所述第二时间点与所述时间间隔相加,得到所述第一时间点。该时间间隔指的是第二时间点后能够进行数据续传所需要间隔的时间,即
Figure PCTCN2018076046-appb-000004
其中,
Figure PCTCN2018076046-appb-000005
为终端检测到续传调度信息的第二时间点,k为该第二时间点与第一时间点的时间间隔,k≥0,
Figure PCTCN2018076046-appb-000006
为第一时间点,也就是重复性数据续传开始的子帧索引。
例如,当k的取值为0时,在第二时间点所在的TTI开始发送重复性的续传数据。
再例如,如图6所示,在前信道占用时间311具有未完成的重复性数据传输,当终端检测到基站在当前信道占用时间321内进行了续传调度信息的发送时,获取发送该续传调度信息的第二时间点,即图6中标注为A的TTI,当检测到续传调度信息中k=1时,可以在第二时间点后第一个TTI,也就是图6中标注为C的TTI,开始重复性的数据续传。其中,重复性数据传输进行的时长如时间窗口331所示。
需要补充的是,在上述实施例一至三中,获取基站发布的续传调度信息的步骤,还具有以下多种实现方式:
在一种可选的实现方式中,可检测公共控制信道内是否具有基站发布的续传调度信息,其中,公共控制信道为原有公共控制信道或新分配资源的公共控制信道,且小区内所有用户都基于该续传调度信息,判断是否有数据续传。
也就是说,可以使用原有的公共控制信道获取基站发布的续传调度信息,这里,需要额外引入新的指示信息,用于指示续传。例如,1比特指示信息,指示用户是否有续传。或者,也可以使用新的时频资源,用新时频资源所在的公共控制信道获取基站发布的续传调度信息,这就避免了因原有的公共控制信道传输能力弱而导致数据传输中断时,仍使用传输能力弱的原有的公共控制信道,避免 数据续传失败,提升通信效率。
在另一种可选的实现方式中,检测下行控制信道内是否具有基站发布的共享续传调度信息;当检测到下行控制信道内具有多用户共享续传调度信息时,根据终端的用户标识,从多用户共享续传调度信息中获取用户标识对应的续传控制指示,续传控制指示包括可续传指示和不续传指示;当续传控制指示为可续传指示时,允许进行数据续传。
基站可直接发布多个共享续传调度信息,每个共享续传调度信息承载多个续传控制指示,其中,不同共享续传调度信息对应不同组的通信设备,同一个多用户共享续传调度信息内不同的续传控制指示对应不同的通信设备。这样,当终端检测到多用户共享续传调度信息后,可直接在其中识别出与自身用户标识对应的续传控制指示,以完成数据续传。这样,基站减少了发布续传调度信息的次数,提升了通信效率。
在又一种可选的实现方式中,在一新分配的时频资源内,检测一个新的物理信道内是否具有基站发布的续传调度信息,其中,续传调度信息为一个序列。将续传调度信息设置为一个序列,那么终端在检测过程中,只有检测到该序列,即可开始进行数据续传,检测不到该序列,则不进行数据续传,简化了终端判断是否进行数据续传的步骤,提升了终端的工作效率。进一步,这一新分配的时频资源是多用户共享的。即一个序列可以对应多个用户,指示是否续传。

实施例五
图8示出了本申请的一个实施例的数据时域传输控制方法的流程图。
如图8所示,本申请的一个实施例的数据时域传输控制方法,用于控制在非授权频段重复性传输数据,包括:
步骤802,检测在前信道占用时间内是否具有未完成的数据传输。
如果具有未完成的数据传输,则可以发布续传调度信息,以便 完成数据传输,提升通信的有效性,如果没有未完成的数据传输,则基站不必动作。
步骤804,当检测到在前信道占用时间内具有未完成的数据传输时,在当前信道占用时间内,发布未完成的数据传输对应的续传调度信息,以供根据基站发布的续传调度信息进行数据续传。
数据续传包括终端向基站上传数据和/或基站向终端下发数据,也就是说,在通过物理上行共享信道或物理下行共享信道进行数据传输的过程中,如果基站检测到在前的信道占用时间内具有未完成的数据传输,都可以发布续传调度信息。
这样,可以避免因在单个信道占用时间内未完成数据的重复性传输而导致的数据传输失败的情况,实现了在非授权频段跨多个信道占用时间的数据续传,增加了基站侧对非授权频段数据传输的调控能力,提升了用户体验。
在本申请上述实施例中,可选地,在步骤804之前,还包括:在当前信道占用时间之前的一在前信道占用时间,发布初始调度信息,其中,初始调度信息与续传调度信息相同或不同。
初始调度信息与续传调度信息中均包括数据传输使用的时频资源,其中,续传调度信息是承载在控制信道上,为了数据传输的方便,续传调度信息和对应数据的初始调度信息可以使用相同的控制信令,即调度信息中包含相同的指示域,且取值相同。
然而,当初始调度信息的时频资源不可用或效率低而导致数据传输中断时,续传调度信息也可以指示不同于初始调度信息的新的时频资源,用于续传,新的时频资源包含频域上的资源、当前信道占用时间内的重复传输次数等,这里的重复传输次数包含频域上的重复次数和时域上的重复传输次数,均可以和上一个信道占用时间不同。由此,可以进一步提升数据续传的成功率。
在本实施例的一种可选实现方式中,步骤804具体包括:通过新分配资源的公共控制信道或原有控制信道发布续传调度信息。
也就是说,基站可以使用原有的公共控制信道发布续传调度信 息,且小区内所有用户都基于该续传调度信息,判断是否有数据续传,这里,需要额外引入新的指示信息,用于指示续传。例如,1比特指示信息,指示用户是否有续传。
或者,也可以使用新的时频资源,用新时频资源所在的公共控制信道发布续传调度信息,这就避免了因原有的公共控制信道传输能力弱而导致数据传输中断时,仍使用传输能力弱的原有的公共控制信道,避免数据续传失败,提升通信效率。
在本实施例的另一种可选实现方式中,步骤804具体包括:发布未完成的数据传输对应的续传调度信息的步骤,具体包括:通过下行控制信道组播发布多用户共享续传调度信息,其中,多用户共享续传调度信息包括多个终端对应的续传控制指示,续传控制指示包括可续传指示和不续传指示。
基站可直接发布多个共享续传调度信息,每个共享续传调度信息承载多个续传控制指示,其中,不同共享续传调度信息对应不同组的通信设备,同一个多用户共享续传调度信息内不同的续传控制指示对应不同的通信设备。这样,当终端检测到多用户共享续传调度信息后,可直接在其中识别出与自身用户标识对应的续传控制指示,以完成数据续传。这样,基站减少了发布续传调度信息的次数,提升了通信效率。
在本实施例的再一种可选实现方式中,步骤804具体包括:发布未完成的数据传输对应的续传调度信息的步骤,具体包括:通过一个新的物理信道组播发布续传调度信息,其中,续传调度信息为一个序列。
将续传调度信息设置为一组序列,使得基站发布的内容更为简单,提升了基站的工作效率,同时,终端在检测过程中,只有检测到该序列,即可开始进行数据续传,检测不到该序列,则不进行数据续传,简化了终端判断是否进行数据续传的步骤,提升了终端的工作效率。
