下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例仅是本发明一部分实施例,而不是全部的实施例。基于本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本发明保护的范围。
本发明实施例公开了一种数据传输的应答指示方法及相关设备,可以同时向一个应答分组中的多个UE联合反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。以下分别进行详细说明。
为了更好的理解本发明实施例公开的一种数据传输的应答指示方法及相关设备,下面先对本发明实施例适用的网络构架进行描述。请参阅图1,图1是本发明实施例公开的一种网络构架示意图。在图1所示的网络构架中,可以包括基站和多个用户设备(User Equipment,简称UE),其中,基站可以通过无线局域网(Wireless Local Area Networks,WLAN)与多个UE进行通信连接。在图1所示的网络构架中,UE可以包括移动手机、平板电脑、掌上电脑、个人数字助理(Personal Digital Assistant,PDA)、移动互联网设备(Mobile Internet Device,MID)、可穿戴式设备(如智能手表、智能手环等)等等,本发明实施例不作限定。
在图1所示的网络构架中,基站可以同时允许多个UE接入,基站可以为接入的多个UE分配传输信道,分配有传输信道的UE在各自对应的传输信道上向基站上行传输数据。此外,基站可能未给接入的部分UE分配任何传输信道,且存在未分配给任何UE的空闲信道时,这些未分配有传输信道的UE可以在未分配给任何UE的空闲信道上通过竞争的方式向基站传输数据。在图1所示的网络构架中,多个用户设备UE1、UE2、……、UEn可以在各自对应的传输信道上向基站上行传输数据,其中,n为大于0的正整数。基站可以对数据进行检测,并向UE反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到。基站可以对接入的UE进行分组,以将多个UE分成若干个应答分组。针对每一个应答分组,基站可以检测该应答分组中UE传输的数据,并向该应答分组中的UE联合反馈应答指示消息,这里可以将UE1、UE2、……、UEn看作是同一个应答分组中的UE,基站检测该应答分组中的数据,并可以以位图或索
引的方式向UE1、UE2、……、UEn联合反馈应答指示消息,该应答分组中的UE可以接收该应答指示消息并解析。通过实施图1所示的网络构架,基站可以同时向一个应答分组中的多个UE联合反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。
基于图1所示的网络构架,本发明实施例公开了一种数据传输的应答指示方法。请参阅图2,图2是本发明实施例公开的一种数据传输的应答指示方法的流程示意图。其中,图2所描述的方法是以位图指示的方式向多个UE联合反馈应答指示消息的。如图2所示,该数据传输的应答指示方法可以包括以下步骤:
201、基站对应答分组中的各个用户设备UE是否传输数据进行检测,以获得检测结果。
本发明实施例中,基站可以对接入的多个UE进行分组,以将多个UE分成若干个应答分组,从而可以方便基站对分组中的UE进行联合处理。其中,一个应答分组中包含基站待检测数据的各个UE,即基站能够对应答分组中包含的各个UE进行数据检测。针对每一个应答分组,基站可以实时对该应答分组中的各个UE是否传输了数据进行检测,以获得检测结果;基站也可以每隔预设时间对该应答分组中的各个UE是否传输了数据进行检测,以获得检测结果,本发明实施例不作限定。
本发明实施例中,基站主要是对通过竞争方式上行传输的数据进行检测,即可以对竞争传输区域内的该应答分组中的UE传输的数据进行盲检,以获得检测结果。
作为一种可选的实施方式,基站以位图的方式向多个UE联合反馈应答指示消息时,基站在执行步骤201对应答分组中的各个用户设备UE是否传输数据进行检测,以获得检测结果之前,图2所描述的方法还可以包括以下步骤:
21)基站向应答分组中的各个用户设备UE发送配置信息,该配置信息用于指示各个UE所属的应答分组、该应答分组中的UE数量以及各个UE在该应答分组中对应的标志位。
在该实施方式中,请一并参阅图3,图3是本发明实施例公开的一种基于位
图的应答指示的初始配置示意图。如图3所示,基站可以将接入的UE分成应答分组1、应答分组2、……、应答分组n,且每个应答分组中包含有若干个UE,其中,n为大于0的正整数,每个应答分组中的UE数量可以相同也可以不同,且每个UE在所属的应答分组内都有一个对应的标志位,即UE在所属的应答分组内的位置。
在该实施方式中,当有UE接入基站时,基站可以为该UE配置与上行数据应答相关的配置信息,并将该配置信息发送给该UE。该配置信息可以包括小区特定的配置信息(图3未示出)和UE特定的配置信息(如图3所示),其中,小区特定的配置信息可以用于指示UE所在小区的小区ID(即小区标识)、小区SRS(Sounding Reference Signal,探测参考信号)、小区SRS的发送周期以及周期内的偏移量等等,小区特定的配置信息对于同一个小区中的所有UE均是相同的。UE特定的配置信息可以用于指示UE所属的应答分组、该应答分组中的UE数量以及UE在该应答分组中对应的标志位外,还可以用于指示C-RNTI(Cell Radio Network Temporary Identifier,小区无线网络临时标识),即基站分配给UE的一个动态标识。对于不同的UE,其UE特定的配置信息不同。
202、基站根据该检测结果生成第一级应答指示消息,第一级应答指示消息用于指示该应答分组中的各个UE对应的标志位状态,其中,标志位状态包括第一状态或第二状态,第一状态用于指示基站检测到数据,第二状态用于指示基站未检测到数据。
本发明实施例中,基站可以根据对该应答分组中的UE是否传输了数据进行检测得到的检测结果来生成第一级应答指示消息。第一级应答指示消息可以用于指示该应答分组中的各个UE在组内对应的标志位状态,每一个UE对应的标志位状态可以包括第一状态或第二状态,其中,第一状态用于指示基站检测到该UE传输的数据,第二状态用于指示基站未检测到该UE传输的数据。
本发明实施例中,标志位状态可以用1个比特来表示,0和1分别代表两种状态,如1代表第一状态,即基站检测到数据;0代表第二状态,即基站未检测到数据。当基站在该应答分组中检测到某一UE传输的数据时,基站将第一级应答指示消息中该UE对应的标志位置位为1;当基站在该应答分组中未检测到某一UE传输的数据时,基站将第一级应答指示消息中该UE对应的标志位复位
为0。此外,也可以用0代表第一状态,1代表第二状态,本发明实施例不作限定。
本发明实施例中,第一级应答指示消息的数据长度可以由该应答分组中的UE数量决定。例如,当用1个比特来表示一个UE,且该应答分组中一共有10个UE时,第一级应答指示消息的数据长度则为10个比特长度;当用2个比特来表示一个UE时,第一级应答指示消息的数据长度则为20个比特长度。
203、基站发送第一级应答指示消息。
本发明实施例中,基站可以以广播的方式发送第一级应答指示消息,以使该应答分组中传输了数据的UE可以接收第一级应答指示消息。
作为一种可选的实施方式,步骤203基站发送第一级应答指示消息的具体实施方式可以包括:
基站在该应答分组所对应的第一应答资源上发送第一级应答指示消息。
在该实施方式中,该应答分组所对应的第一应答资源可以包括但不限于PDCCH(Physical Downlink Control Channel,物理下行控制信道)或PDSCH(Physical Downlink Shared Channel,物理下行共享信道)。每一个应答分组均有与之对应的应答资源,不同应答分组对应的应答资源不同。
在该实施方式中,基站在该应答分组所对应的第一应答资源上发送第一级应答指示消息,该应答分组中的UE可以接收该第一级应答指示消息,并根据基站发送的配置信息,从第一级应答指示消息中解析出自身对应的标志位状态,以判断自身传输的数据是否被漏检。
在图2所描述的方法中,基站可以对一个应答分组中的各个UE是否传输数据进行检测,以获得检测结果,并根据该检测结果生成第一级应答指示消息,第一级应答指示消息用于指示该应答分组中的各个UE对应的标志位状态,其中,每一个UE对应的标志位状态包括第一状态或第二状态,第一状态用于指示基站检测到该UE传输的数据,第二状态用于指示基站未检测到该UE传输数据,基站可以发送第一级应答指示消息,以使得UE可以接收第一级应答指示消息,并解析第一级应答指示消息中自身对应的标志位状态,通过解析结果来获得自身发送的数据有没有被基站检测到。可见,通过实施图2所描述的方法,在基于竞争传输的上行数据传输模式下,基站可以同时向一个应答分组中的多
个UE联合反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。
基于图1所示的网络构架,本发明实施例公开了另一种数据传输的应答指示方法。请参阅图4,图4是本发明实施例公开的另一种数据传输的应答指示方法的流程示意图。其中,图4所描述的方法是以位图指示的方式向多个UE联合反馈应答指示消息的。如图4所示,该数据传输的应答指示方法可以包括以下步骤:
401、基站对应答分组中的各个用户设备UE是否传输数据进行检测,以获得检测结果。
本发明实施例中,基站与该应答分组中的各个UE之间需建立通信连接。该应答分组中包含基站待检测数据的各个UE。
作为一种可选的实施方式,在执行步骤401之前,图4所描述的方法还可以包括以下步骤:
41)基站向应答分组中的各个用户设备UE发送配置信息,该配置信息用于指示各个UE所属的应答分组、该应答分组中的UE数量以及各个UE在该应答分组中对应的标志位。
402、基站根据该检测结果生成第一级应答指示消息,第一级应答指示消息用于指示该应答分组中的各个UE对应的标志位状态,其中,标志位状态包括第一状态或第二状态,第一状态用于指示基站检测到数据,第二状态用于指示基站未检测到数据。
本发明实施例中,第一级应答指示消息的数据长度是由该应答分组中的UE数量决定的。
403、基站发送第一级应答指示消息。
作为一种可选的实施方式,步骤403基站发送第一级应答指示消息的具体实施方式包括:
基站在该应答分组所对应的第一应答资源上发送第一级应答指示消息。
404、当该应答分组中的各个UE中存在目标UE时,基站对目标UE传输的
数据进行校验,以获得校验结果。
本发明实施例中,目标UE是指标志位状态为第一状态的所有UE,即基站检测到数据的UE。基站可以对所有检测到数据的目标UE传输的数据进行校验,以获得校验结果。
405、基站根据该校验结果生成第二级应答指示消息,第二级应答指示消息用于指示针对目标UE传输的数据对应的应答反馈信息的类型,其中,应答反馈信息的类型包括第一类型或第二类型,第一类型用于指示基站校验数据成功,第二类型用于指示基站校验数据失败。
本发明实施例中,基站可以根据对所有的目标UE传输的数据进行校验得到的校验结果来生成第二级应答指示消息。第二级应答指示消息可以用于指示针对目标UE传输的数据对应的应答反馈信息的类型,每一个目标UE对应的应答反馈信息的类型可以包括第一类型或第二类型,其中,第一类型用于指示基站对该目标UE传输的数据校验成功,第二类型用于指示基站对该目标UE传输的数据校验失败。
本发明实施例中,应答反馈信息的类型可以用1个比特来表示,0和1分别代表两种类型,如1代表第一类型,即基站校验数据成功;0代表第二类型,即基站校验数据失败。当基站对某一目标UE传输的数据校验成功时,基站将第二级应答指示消息中该目标UE对应的位置置位为1,可以看作基站对该目标UE反馈确定应答;当基站对某一目标UE传输的数据校验失败时,基站将第二级应答指示消息中该目标UE对应的位置复位为0,可以看作基站对该目标UE反馈否定应答。此外,也可以用0代表第一类型,1代表第二类型,本发明实施例不作限定。
本发明实施例中,第二级应答指示消息的数据长度由该应答分组中标志位状态为第一状态的目标UE的数量决定。例如,当用1个比特来表示一个目标UE,且目标UE的个数为5时,第二级应答指示消息的数据长度则为5比特长度;当用2个比特来表示一个目标UE时,第二级应答指示消息的数据长度则为10比特长度。基站可以通过统计该应答分组中标志位状态为第一状态的目标UE的数量,以及每个目标UE在该应答分组中的位置来确定每个目标UE在第二级应答指示消息中所对应的位置。
请一并参阅图5,图5是本发明实施例公开的一种基于位图的应答指示消息的示意图。如图5所示,针对每一个应答分组,基站首先生成第一级应答指示消息,其中,每一个UE用1个比特来表示,1代表基站检测到了该UE传输的数据,0代表基站未检测到该UE传输的数据,第一级应答指示消息的数据长度由该应答分组中的UE数量决定,例如当该应答分组中的UE数量为10时,第一级应答指示消息的数据长度为10比特长度。基站可以获取第一级应答指示消息中标志位状态为第一状态(即标志位状态为1)的所有目标UE,并对这些目标UE传输的数据进行校验,以生成第二级应答指示消息。图5中所示,每一个目标UE在第二级应答指示消息中可以用1个比特来表示,其中,应答分组1所对应的第二级应答指示消息的数据长度为4比特(即其中有4个目标UE),应答分组2所对应的第二级应答指示消息的数据长度为5比特(即其中有5个目标UE),应答分组n所对应的第二级应答指示消息的数据长度为6比特(即其中有6个目标UE)。第二级应答指示消息中1代表基站对该目标UE传输的数据校验成功,0表示基站对该目标UE传输的数据校验失败。
作为一种可选的实施方式,当第二级应答指示消息中存在针对至少一个目标UE传输的数据对应的应答反馈信息的类型为第二类型,即基站对至少一个目标UE传输的数据校验失败时,第二级应答指示消息还可以用于指示针对上述至少一个目标UE传输的数据对应的校验失败状态,校验失败状态包括第三状态或第四状态,第三状态用于指示数据校验失败由上行多用户配对匹配度差引起的冲突导致的,第四状态用于指示数据校验失败由数据传输信道质量差导致的。
在该实施方式中,校验失败状态可以看作是由什么原因导致的数据校验失败。此时,第二级应答指示消息中每一个目标UE可以用2个比特来表示,其中,一个比特用于指示基站对该目标UE传输的数据进行校验是否成功,例如1代表校验成功,0代表校验失败;另一个比特用于指示基站对该目标UE传输的数据校验失败的原因,例如1代表数据校验失败是由上行多用户配对匹配度差引起的冲突导致的,0代表数据校验失败是由数据传输信道质量差导致的。此时,第二级应答指示消息的数据长度是由1个比特来表示一个目标UE时的数据长度的两倍,例如,当用1个比特来表示一个目标UE时,在有5个目标UE的情况
下,第二级应答指示消息的数据长度为5比特长度;当用2个比特来表示一个目标UE时,第二级应答指示消息的数据长度则变为10比特长度。当基站对某个目标UE传输的数据校验成功时,则用于指示数据校验失败状态的比特位可以用无效字符Invalid或空字符Null来表示,也可以用其他约定的方式进行表示,该实施方式不作限定。实施该实施方式,能够使UE明确基站对该UE传输的数据校验失败的原因,使基站和UE之间的通信更加透明化。
406、基站发送第二级应答指示消息。
作为一种可选的实施方式,步骤406基站发送第二级应答指示消息的具体实施方式可以包括:
基站在该应答分组所对应的第二应答资源上发送第二级应答指示消息。
在该实施方式中,用于发送第一级应答指示消息的第一应答资源与用于发送第二级应答指示消息的第二应答资源可以为不同的应答资源。当基站在该应答分组所对应的PDCCH上发送第一级应答指示消息时,基站也可以在该应答分组所对应的PDCCH上发送第二级应答指示消息,此时,第一级应答指示消息和第二级应答指示消息是在PDCCH中的不同频域资源上进行发送的,即在PDCCH中的不同频域子信道上进行发送。同样的,当基站在该应答分组所对应的PDSCH上发送第一级应答指示消息时,基站也可以在该应答分组所对应的PDSCH上发送第二级应答指示消息,此时,第一级应答指示消息和第二级应答指示消息是在PDSCH中的不同频域资源上进行发送的,即在PDSCH中的不同频域子信道上进行发送。
作为一种可选的实施方式,当该应答分组中的所有UE对应的标志位状态均为第二状态,即基站未检测到该应答分组中的所有UE传输的数据时,基站则无需进行数据校验操作,即无需执行步骤404至406,只需发送第一级应答指示消息即可。
通过实施图4所描述的方法,在基于竞争传输的上行数据传输模式下,基站可以同时向一个应答分组中的多个UE联合反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。此外,利用位图的方式反馈应答消息,可以以两级指示的方式进行回馈,在指示了数据检测结果的基础上,可以进一
步指示数据校验结果,以使UE及时了解自身传输的数据是否被基站校验成功。
基于图1所示的网络构架,本发明实施例公开了又一种数据传输的应答指示方法。请参阅图6,图6是本发明实施例公开的又一种数据传输的应答指示方法的流程示意图。其中,图6所描述的方法是以索引指示的方式向多个UE联合反馈应答指示消息的。如图6所示,该数据传输的应答指示方法可以包括以下步骤:
601、基站对应答分组中的各个UE是否传输数据进行检测,以获得检测结果。
本发明实施例中,在基于竞争传输的上行数据传输模式下,基站可以对接入的多个UE进行分组,以将多个UE分成若干个应答分组。一个应答分组中包含基站待检测数据的各个UE。针对每一个应答分组,基站可以实时对该应答分组中的各个UE是否传输了数据进行检测,以获得检测结果;基站也可以每隔预设时间对该应答分组中的各个UE是否传输了数据进行检测,以获得检测结果,本发明实施例不作限定。
作为一种可选的实施方式,基站以索引的方式向多个UE联合反馈应答指示消息时,基站在执行步骤601之前,图6所描述的方法还可以包括以下步骤:
61)基站向应答分组中的各个UE发送配置信息,该配置信息用于指示各个UE所属的应答分组、基站在该应答分组中预设反馈的UE数量以及各个UE在该应答分组中对应的索引号。
在该实施方式中,当有UE接入基站时,基站可以为该UE配置与上行数据应答相关的配置信息,并将该配置信息发送给该UE。该配置信息可以包括小区特定的配置信息和UE特定的配置信息,其中,小区特定的配置信息可以用于指示UE所在小区的小区ID、小区SRS、小区SRS的发送周期以及周期内的偏移量等等,小区特定的配置信息对于同一个小区中的所有UE均是相同的。UE特定的配置信息可以用于指示UE所属的应答分组、基站在该应答分组中预设反馈的UE数量以及UE在该应答分组中对应的索引号外,还可以用于指示C-RNTI,对于不同的UE,其UE特定的配置信息不同。
在该实施方式中,UE在该应答分组中对应的索引号可以用阿拉伯数字1、
2、3等来表示,也可以用二进制00、01、011等来表示,还可以用字符A、B、A1、A2等来表示,本发明实施例不作限定。
602、基站根据该检测结果生成应答指示消息,应答指示消息用于指示该应答分组中的目标UE对应的索引号。
本发明实施例中,基站可以根据对该应答分组中的UE是否传输数据进行检测得到的检测结果生成应答指示消息,应答指示消息可以用于指示该应答分组中的目标UE对应的索引号,其中,目标UE为基站在该应答分组中检测到数据的至少一个UE,索引号为目标UE在该应答分组中的编号,在该应答分组中不同的目标UE对应的索引号不同。当基站在该应答分组中检测到某一目标UE传输的数据时,基站在应答指示消息中添加该目标UE对应的索引号;当基站在该应答分组中未检测到某一目标UE传输的数据时,基站则不会将该目标UE对应的索引号添加进应答指示消息中。当基站在该应答分组中均未检测到UE传输的数据时,此时目标UE不存在,则应答指示消息中可以用无效字符Invalid或空字符Null来填充。
本发明实施例中,应答指示消息的数据长度为预设数据长度,即该应答指示消息的数据长度为可配置的,可以由基站预先设定,不受该应答分组中UE数量的变化而变化。应答指示消息的数据长度可以由配置信息中的基站在该应答分组中预设反馈的UE数量决定,应答指示消息中包括的索引号的数量一般不超过该预设数据长度,例如,当基站在该应答分组中预设反馈的UE数量为5个时,应答指示消息中最多只能包含5个索引号,当基站检测到多于5个目标UE传输的数据时,基站将会舍弃多于的目标UE对应的索引号;当基站检测到少于5个目标UE传输的数据时,基站可以将应答指示消息中多出来的位置用无效字符Invalid或空字符Null来表示。为防止资源的浪费,一般预设数据长度可配置的最大长度可以由该应答分组中的UE数量决定,例如,当用1个比特来指示一个UE时,在该应答分组中包含10个UE的情况下,该预设数据长度最大可为10比特长度;当用2个比特来指示一个UE时,该预设数据长度最大可为20比特长度。针对不同的应答分组,基站设定的应答指示消息的数据长度可以不同。
603、基站发送应答指示消息。
本发明实施例中,基站可以以广播的方式发送应答指示消息。
作为一种可选的实施方式,步骤603基站发送应答指示消息的具体实施方式可以包括:
基站在该应答分组所对应的应答资源上发送应答指示消息。
在该实施方式中,该应答分组所对应的应答资源可以包括但不限于PDCCH或PDSCH,每一个应答分组均有与之对应的应答资源,不同应答分组对应的应答资源不同。
在该实施方式中,基站在该应答分组所对应的应答资源上发送应答指示消息,该应答分组中的UE可以接收该应答指示消息,并根据基站发送的配置信息,对该应答指示消息进行解析,以检测该应答指示消息中是否存在自身所对应的索引号,当某一UE检测到该应答指示消息中存在自身对应的索引号时,则可以说明基站检测到该UE传输的数据;当某一UE在该应答指示消息中未检测到自身对应的索引号时,则可以说明基站未检测到该UE传输的数据。
在图6所描述的方法中,基站可以对一个应答分组中的各个UE是否传输数据进行检测,以获得检测结果,并根据该检测结果生成应答指示消息,应答指示消息用于指示该应答分组中的目标UE对应的索引号,其中,目标UE为基站在该应答分组中检测到数据的至少一个UE,并可以发送应答指示消息。可见,通过实施图6所描述的方法,在基于竞争传输的上行数据传输模式下,基站可以同时向一个应答分组中的多个UE联合反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。
基于图1所示的网络构架,本发明实施例公开了又一种数据传输的应答指示方法。请参阅图7,图7是本发明实施例公开的又一种数据传输的应答指示方法的流程示意图。其中,图7所描述的方法是以索引指示的方式向多个UE联合反馈应答指示消息的。如图7所示,该数据传输的应答指示方法可以包括以下步骤:
701、基站对应答分组中的各个UE是否传输数据进行检测,以获得检测结果,其中,该应答分组中包含基站待检测数据的各个UE。
作为一种可选的实施方式,在执行步骤701之前,图7所描述的方法还可以
包括以下步骤:
71)基站向应答分组中的各个UE发送配置信息,该配置信息用于指示各个UE所属的应答分组、基站在该应答分组中预设反馈的UE数量以及各个UE在该应答分组中对应的索引号。
702、基站根据该检测结果生成应答指示消息,应答指示消息用于指示该应答分组中的目标UE对应的索引号以及目标UE对应的索引号的标志位。
本发明实施例中,目标UE为基站在该应答分组中检测到数据的至少一个UE,索引号为目标UE在该应答分组中的编号,在该应答分组中不同的目标UE对应的索引号不同。
本发明实施例中,应答指示消息的数据长度为预设数据长度,应答指示消息指示的目标UE对应的索引号的数量不超过该预设数据长度。
703、基站对目标UE传输的数据进行校验,以获得校验结果。
本发明实施例中,当基站在该应答分组中检测到了目标UE传输的数据时,基站可以对目标UE传输的数据进行校验,以获得校验结果。
704、基站根据该校验结果生成目标UE对应的索引号的标志位状态,其中,索引号的标志位状态包括第一状态或第二状态,第一状态用于指示基站校验数据成功,第二状态用于指示基站校验数据失败。
本发明实施例中,可以在应答指示消息中指示的每一个索引号后预留1比特标志位,通过数据校验结果可以生成标志位状态,可以利用0和1分别代表标志位的两种状态,例如1代表第一状态,0代表第二状态。当基站对某一目标UE传输的数据校验成功时,基站将该目标UE对应的索引号的标志位置位为1,可以看作基站对该目标UE反馈确定应答;当对某一目标UE传输的数据校验失败时,基站将该目标UE对应的索引号的标志位复位为0,可以看作基站对该目标UE反馈否定应答。此外,也可以用0代表第一类型,1代表第二类型,本发明实施例不作限定。
请一并参阅图8,图8是本发明实施例公开的一种基于索引的应答指示消息的示意图。如图8所示,针对每一个应答分组,基站将检测到数据的UE对应的索引号Index加入该应答分组对应的应答指示消息中,并在索引号后预留1比特标志位,当标志位状态为1时,说明基站对该索引号对应的UE传输的数据校验
成功,此时,基站向该UE反馈确定应答;当标志位状态为0时,说明基站对该索引号对应的UE传输的数据校验失败,此时,基站向该UE反馈否定应答。由于每一个应答分组对应的应答指示消息的数据长度为基站预定好的,当基站在某一个应答分组中检测到数据的UE数量超出应答指示消息的数据长度时,则舍去多于的UE;当基站在某一个应答分组中检测到数据的UE数量小于应答指示消息的数据长度时,可以在多出来的位置处填充Null或Invalid。
作为一种可选的实施方式,当应答指示消息中存在目标UE对应的索引号的标志位状态为第二状态,即基站对目标UE传输的数据校验失败时,应答指示消息还可以用于指示索引号的标志位状态为第二状态的目标UE传输的数据对应的校验失败状态,校验失败状态包括第三状态或第四状态,第三状态用于指示数据校验失败由上行多用户配对匹配度差引起的冲突导致的,第四状态用于指示数据校验失败由数据传输信道质量差导致的。
在该实施方式中,针对每一个检测到数据的目标UE,应答指示消息中可以用3个比特来指示,其中,第一个比特用于指示该目标UE的索引号;第二个比特用于指示索引号的标志位状态,例如1代表校验成功,0代表校验失败;第三个比特用于指示基站对该目标UE传输的数据对应的校验失败状态,例如1代表数据校验失败是由上行多用户配对匹配度差引起的冲突导致的,0代表数据校验失败是由数据传输信道质量差导致的。实施该实施方式,能够使UE明确基站对该UE传输的数据校验失败的原因,使基站和UE之间的通信更加透明化。
705、基站发送应答指示消息。
作为一种可选的实施方式,步骤705基站发送应答指示消息的具体实施方式可以包括:
基站在该应答分组所对应的应答资源上发送应答指示消息。
通过实施图7所描述的方法,在基于竞争传输的上行数据传输模式下,基站可以同时向一个应答分组中的多个UE联合反馈应答指示消息,以使UE及时了解自身传输的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。此外,利用索引的方式反馈应答消息,可以在指示了数据检测结果的基础上,进一步指示数据校验结果,以使UE及
时了解自身传输的数据是否被基站校验成功。
基于图1所示的网络构架,本发明实施例公开了又一种数据传输的应答指示方法。请参阅图9,图9是本发明实施例公开的又一种数据传输的应答指示方法的流程示意图。其中,图9所描述的方法是以位图指示的方式向多个UE联合反馈应答指示消息的。如图9所示,该数据传输的应答指示方法可以包括以下步骤:
901、用户设备UE向基站发送数据后,接收基站反馈的第一级应答指示消息,第一级应答指示消息用于指示该UE所属的应答分组中的各个UE对应的标志位状态,其中,标志位状态包括第一状态或第二状态,第一状态用于指示基站检测到数据,第二状态用于指示基站未检测到数据。
本发明实施例中,当UE向基站上行发送数据后,该UE可以接收基站以位图的方式反馈的第一级应答指示消息。第一级应答指示消息用于指示该UE所属的应答分组中的各个UE对应的标志位状态,标志位状态可以用于指示该UE发送的数据是否被基站检测到。其中,该应答分组中包含基站待检测数据的各个UE。
本发明实施例中,第一级应答指示消息的数据长度由该UE所属的应答分组中的UE数量决定。
作为一种可选的实施方式,在执行步骤901之前,图9所描述的方法还可以包括以下步骤:
91)UE接收基站发送的配置信息,该配置信息用于指示该UE所属的应答分组、该应答分组中的UE数量以及该UE在该应答分组中对应的标志位。
在该实施方式中,该配置信息还可以用于指示该UE所在小区的小区ID、小区SRS、小区SRS的发送周期以及周期内的偏移量等等信息。
902、UE从第一级应答指示消息中解析该UE在该应答分组中对应的标志位状态。
本发明实施例中,UE接收到基站反馈的第一级应答指示消息后,可以根据接收到的配置信息,从该第一级应答指示消息中解析出自身在该应答分组中对应的标志位状态。标志位状态可以用1个比特来表示,0和1分别代表两种状
态,如1代表第一状态,即基站检测到数据;0代表第二状态,即基站未检测到数据。当UE从第一级应答指示消息中解析出该UE在该应答分组中的标志位状态为1(即第一状态)时,说明基站检测到了该UE发送的数据;当UE从第一级应答指示消息中解析出该UE在该应答分组中的标志位状态为0(即第二状态)时,说明基站漏检了该UE发送的数据。
通过实施图9所描述的方法,UE在通过竞争方式向基站发送数据后,可以接收基站向多个UE联合反馈的应答指示消息,并通过解析该应答指示消息来及时了解自身发送的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。
基于图1所示的网络构架,本发明实施例公开了又一种数据传输的应答指示方法。请参阅图10,图10是本发明实施例公开的又一种数据传输的应答指示方法的流程示意图。其中,图10所描述的方法是以位图指示的方式向多个UE联合反馈应答指示消息的。如图10所示,该数据传输的应答指示方法可以包括以下步骤:
1001、用户设备UE向基站发送数据后,接收基站反馈的第一级应答指示消息,第一级应答指示消息用于指示该UE所属的应答分组中的各个UE对应的标志位状态,其中,标志位状态包括第一状态或第二状态,第一状态用于指示基站检测到数据,第二状态用于指示基站未检测到数据。
本发明实施例中,该应答分组中包括基站待检测数据的各个UE。第一级应答指示消息的数据长度由该UE所属的应答分组中的UE数量决定。
作为一种可选的实施方式,步骤1001用户设备UE向基站发送数据后,接收基站反馈的第一级应答指示消息的具体实施方式可以包括:
用户设备UE向基站发送数据后,接收基站在该UE所属的应答分组所对应的第一应答资源上反馈的第一级应答指示消息。
其中,应答分组所对应的第一应答资源可以包括但不限于PDCCH或PDSCH,且不同的应答分组对应的应答资源不同。
作为一种可选的实施方式,在执行步骤1001之前,图10所描述的方法还可以包括以下步骤:
100)UE接收基站发送的配置信息,该配置信息用于指示该UE所属的应答分组、该应答分组中的UE数量以及该UE在该应答分组中对应的标志位。
1002、UE从第一级应答指示消息中解析该UE在该应答分组中对应的标志位状态,以检测该标志位状态是否为第一状态,若是,则执行步骤1003;若否,则执行步骤1005。
1003、UE接收基站反馈的第二级应答指示消息,第二级应答指示消息用于指示针对目标UE发送的数据对应的应答反馈信息的类型,其中,应答反馈信息的类型包括第一类型或第二类型,第一类型用于指示基站校验数据成功,第二类型用于指示基站校验数据失败。
本发明实施例中,当UE解析出该UE在该应答分组中对应的标志位状态为第一状态,即基站检测到该UE发送的数据时,UE可以接收基站反馈的第二级应答指示消息。目标UE是指该应答分组中标志位状态为第一状态的所有UE。
作为一种可选的实施方式,步骤1003UE接收基站反馈的第二级应答指示消息的具体实施方式可以包括:
UE接收基站在该UE所属的应答分组所对应的第二应答资源上反馈的第二级应答指示消息。
其中,第二应答资源与第一应答资源不同,用于反馈第一级应答指示消息的第一应答资源与用于反馈第二级应答指示消息的第二应答资源可以是PDCCH中的不同频域的子信道,也可以是PDSCH中的不同频域的子信道,本发明实施例不作限定。
1004、UE从第二级应答指示消息中解析针对该UE发送的数据对应的应答反馈信息的类型。
本发明实施例中,UE解析出该UE在该应答分组中对应的标志位状态为第一状态,即UE解析出基站检测到该UE发送的数据。进一步地,该UE可以接收基站反馈的第二级应答指示消息,以通过解析第二级应答指示消息来检测该UE发送的数据是否校验成功。当针对该UE发送的数据对应的应答反馈信息的类型为第一类型时,说明基站对该UE发送的数据校验成功,此时,基站向该UE反馈确定应答;当针对该UE发送的数据对应的应答反馈信息的类型为第二类型时,说明基站对该UE发送的数据校验失败,此时,基站向该UE反馈否定
应答。
本发明实施例中,第二级应答指示消息的数据长度由该应答分组中标志位状态为第一状态的目标UE的数量决定的。
作为一种可选的实施方式,步骤1004UE从第二级应答指示消息中解析针对该UE发送的数据对应的应答反馈信息的类型的具体实施方式可以包括以下步骤:
101)UE统计目标UE的数量;
102)UE确定该UE在目标UE中的位置,其中,该UE在第二级应答指示消息中的位置由该UE在目标UE中的位置决定;
103)UE从该UE在第二级应答指示消息中的位置处解析针对该UE发送的数据的应答反馈信息的类型。
在该实施方式中,当UE接收到第一级应答指示消息后,可以统计第一级应答指示消息中标志位状态为第一状态的目标UE的数量,并根据该UE在第一级应答指示消息中的位置来确定该UE在目标UE中的位置。可以按照目标UE在第一级应答指示消息中的排序来确定第二级应答指示消息中目标UE的排列顺序,从而进一步确定该UE在第二级应答指示消息中的位置,并从该UE在第二级应答指示消息中的位置处解析出针对该UE发送的数据的应答反馈信息的类型。
作为一种可选的实施方式,图10所描述的方法还可以包括以下步骤:
104)当UE解析出针对该UE发送的数据的应答反馈信息的类型为第一类型时,UE确定基站对该UE发送的数据校验成功。
作为一种可选的实施方式,图10所描述的方法还可以包括以下步骤:
105)当UE解析出针对该UE发送的数据的应答反馈信息的类型为第二类型时,UE确定基站对该UE发送的数据校验失败。
作为一种可选的实施方式,当第二级应答指示消息中存在针对至少一个目标UE传输的数据对应的应答反馈信息的类型为第二类型时,第二级应答指示消息还用于指示针对上述至少一个目标UE发送的数据对应的校验失败状态,校验失败状态包括第三状态或第四状态,第三状态用于指示数据校验失败由上行多用户配对匹配度差引起的冲突导致的,第四状态用于指示数据校验失败由
数据传输信道质量差导致的。
相应地,当UE解析出针对该UE发送的数据的应答反馈信息的类型为第二类型时,图10所描述的方法还可以包括以下步骤:
106)UE从第二级应答指示消息中解析针对该UE发送的数据对应的校验失败状态;
107)当UE解析出针对该UE发送的数据对应的校验失败状态为第三状态时,UE确定基站对该UE发送的数据校验失败是由上行多用户配对匹配度差引起的冲突导致的;
108)当UE解析出针对该UE发送的数据对应的校验失败状态为第四状态时,UE确定基站对该UE发送的数据校验失败是由数据传输信道质量差导致的。
1005、UE确定基站未检测到该UE发送的数据。
本发明实施例中,当UE解析出该UE在该应答分组中对应的标志位状态不为第一状态时,则表明该UE在该应答分组中对应的标志位状态为第二状态,即基站未检测到该UE发送的数据,则UE确定基站漏检了该UE发送的数据,此时UE可以再次向基站发送数据。
通过实施图10所描述的方法,UE在通过竞争方式向基站发送数据后,可以接收基站向多个UE联合反馈的应答指示消息,并通过解析该应答指示消息来及时了解自身发送的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。此外,利用位图的方式反馈应答信息,可以以两级指示的方式进行应答回馈,UE在第一级指示消息中解析出自身发送的数据被基站检测到之后,可以在第二级指示消息中解析数据校验结果,使得UE及时了解自身发送的数据是否被基站校验成功。
基于图1所示的网络构架,本发明实施例公开了又一种数据传输的应答指示方法。请参阅图11,图11是本发明实施例公开的又一种数据传输的应答指示方法的流程示意图。其中,图11所描述的方法是以索引指示的方式向多个UE联合反馈应答指示消息的。如图11所示,该数据传输的应答指示方法可以包括以下步骤:
1101、用户设备UE向基站发送数据后,接收基站反馈的应答指示消息,应答指示消息用于指示该UE所属的应答分组中的目标UE对应的索引号。
本发明实施例中,目标UE为基站在该应答分组中检测到数据的至少一个UE,索引号为目标UE在该应答分组中的临时编号,在该应答分组中不同的目标UE对应的索引号不同,该应答分组中包含基站待检测数据的各个UE。
本发明实施例中,应答指示消息的数据长度为预设数据长度,应答指示消息指示的该应答分组中的目标UE对应的索引号的数量不超过预设数据长度。
作为一种可选的实施方式,步骤1101用户设备UE向基站发送数据后,接收基站反馈的应答指示消息的具体实施方式可以包括:
用户设备UE向基站发送数据后,接收基站在该UE所属的应答分组所对应的应答资源上接收基站反馈的应答指示消息。
其中,应答分组所对应的应答资源可以包括但不限于PDCCH或PDSCH,且不同的应答分组对应的应答资源不同。
作为一种可选的实施方式,在执行步骤1101之前,图11所描述的方法还可以包括以下步骤:
110)UE接收基站发送的配置信息,该配置信息用于指示该UE所属的应答分组、基站在该应答分组中预设反馈的UE数量以及该UE在该应答分组中对应的索引号。
在该实施方式中,该配置信息还可以用于指示该UE所在小区的小区ID、小区SRS、小区SRS的发送周期以及周期内的偏移量等等信息。
1102、UE解析应答指示消息,以检测在应答指示消息中是否存在该UE对应的索引号。
本发明实施例中,应答指示消息中包含有基站检测到数据的目标UE对应的索引号,UE可以根据配置信息从应答指示消息中解析是否存在该UE对应的索引号。当应答指示消息中存在该UE对应的索引号,可以说明基站检测到该UE发送的数据;当应答指示消息中不存在该UE对应的索引号,可以说明基站漏检了该UE发送的数据。此外,由于应答指示消息的数据长度为基站预定的固定长度,当基站检测到数据的UE数量超过了应答指示消息的数据长度,则基站会舍去多余的UE,所以当应答指示消息中不存在该UE对应的索引号有可
能是因为应答指示消息由于长度的限制而无法指示造成的,此时UE会认为基站未检测到数据而重新向基站发送数据。
通过实施图11所描述的方法,UE在通过竞争方式向基站发送数据后,可以接收基站向多个UE联合反馈应答指示消息,并通过解析该应答指示消息来及时了解自身发送的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。
基于图1所示的网络构架,本发明实施例公开了又一种数据传输的应答指示方法。请参阅图12,图12是本发明实施例公开的又一种数据传输的应答指示方法的流程示意图。其中,图12所描述的方法是以索引指示的方式向多个UE联合反馈应答指示消息的。如图12所示,该数据传输的应答指示方法可以包括以下步骤:
1201、用户设备UE向基站发送数据后,接收基站反馈的应答指示消息,应答指示消息用于指示该UE所属的应答分组中的目标UE对应的索引号以及目标UE对应的索引号的标志位。
本发明实施例中,目标UE为基站在该应答分组中检测到数据的至少一个UE,索引号为目标UE在该应答分组中的临时编号,在该应答分组中不同的目标UE对应的索引号不同,该应答分组中包含基站待检测数据的各个UE。

作为一种可选的实施方式,图12所描述的方法还可以包括以下步骤:
120)UE接收基站发送的配置信息,该配置信息用于指示该UE所属的应答分组、基站在该应答分组中预设反馈的UE数量以及该UE在该应答分组中对应的索引号。
1202、UE解析应答指示消息,以检测在应答指示消息中是否存在该UE对应的索引号,若是,则执行步骤1203;若否,则执行步骤1204。
1203、UE解析该UE对应的索引号的标志位状态,其中,索引号的标志位状态包括第一状态或第二状态,第一状态用于指示基站校验数据成功,第二状态用于指示基站校验数据失败。
本发明实施例中,当UE解析出在该应答指示消息中存在该UE对应的索引号时,UE可以进一步解析该UE对应的索引号的标志位状态。
作为一种可选的实施方式,图12所描述的方法还可以包括以下步骤:
121)当UE解析出该UE对应的索引号的标志位状态为第一状态时,UE确定基站对该UE发送的数据校验成功。
作为一种可选的实施方式,图12所描述的方法还可以包括以下步骤:
122)当UE解析出该UE对应的索引号的标志位状态为第二状态时,UE确定基站对该UE发送的数据校验失败。
作为一种可选的实施方式,当应答指示消息中存在目标UE对应的索引号的标志位状态为第二状态时,应答指示消息还用于指示索引号的标志位状态为第二状态的目标UE发送的数据对应的校验失败状态,校验失败状态包括第三状态或第四状态,第三状态用于指示数据校验失败由上行多用户配对匹配度差引起的冲突导致的,第四状态用于指示数据校验失败由数据传输信道质量差导致的。
相应地,当UE解析出该UE对应的索引号的标志位状态为第二状态时,图12所描述的方法还可以包括以下步骤:
123)UE从应答指示消息中解析该UE发送的数据对应的校验失败状态;
124)当UE解析出该UE发送的数据对应的校验失败状态为第三状态时,UE确定基站对该UE发送的数据校验失败是由上行多用户配对匹配度差引起的冲突导致的;
125)当UE解析出该UE发送的数据对应的校验失败状态为第四状态时,UE确定基站对该UE发送的数据校验失败是由数据传输信道质量差导致的。
1204、UE确定基站未检测到该UE发送的数据。
本发明实施例中,当UE解析出在该应答指示消息中不存在该UE对应的索引号时,表明基站未检测到该UE发送的数据,UE可以确定基站漏检了该UE发送的数据。
通过实施图12所描述的方法,UE在通过竞争方式向基站发送数据后,可以接收基站向多个UE联合反馈的应答指示消息,并通过解析该应答指示消息来及时了解自身发送的数据是否被基站检测到,从而可以解决UE传输了数据
而基站漏检且没有反馈应答指示消息的问题。此外,利用索引的方式反馈应答信息,UE在解析出自身发送的数据被基站检测到之后,可以进一步解析数据校验结果,使得UE及时了解自身发送的数据是否被基站校验成功。
基于图1所示的网络构架,本发明实施例公开了一种基站。请参阅图13,图13是本发明实施例公开的一种基站的结构示意图,可以用于执行本发明实施例公开的数据传输的应答指示方法。如图13所示,该基站可以包括:
检测单元1301,用于对应答分组中的各个用户设备UE是否传输数据进行检测,以获得检测结果。

具体地,图21所示的用户设备可以实施本发明结合图9或图10介绍的数据
传输的应答指示方法实施例中的部分或全部流程。
可见,实施图21所示的用户设备,UE在通过竞争方式向基站发送数据后,可以接收基站向多个UE联合反馈的应答指示消息,并通过解析该应答指示消息来及时了解自身发送的数据是否被基站检测到,从而可以解决UE传输了数据而基站漏检且没有反馈应答指示消息的问题。此外,以两级指示的方式进行应答回馈,UE在第一级指示消息中解析出自身发送的数据被基站检测到之后,可以在第二级指示消息中解析数据校验结果,使得UE及时了解自身发送的数据是否被基站校验成功。
基于图1所示的网络构架,本发明实施例公开了又一种用户设备。请参阅图22,图22是本发明实施例公开的又一种用户设备的结构示意图,用于执行本发明实施例公开的数据传输的应答指示方法。如图22所示,该用户设备UE可以包括:
接收单元2201,用于在UE向基站发送数据后,接收基站反馈的应答指示消息,应答指示消息用于指示该UE所属的应答分组中的目标UE对应的索引号。
本发明实施例中,目标UE为基站在该应答分组中检测到数据的至少一个UE,索引号为目标UE在该应答分组中的编号,在该应答分组中不同的目标UE对应的索引号不同,该应答分组中包含基站待检测数据的各个UE。
本发明实施例中,应答指示消息的数据长度为预设数据长度,应答指示消息指示的该应答分组中的目标UE对应的索引号的数量不超过预设数据长度。
第一解析单元2202,用于解析应答指示消息,以检测在应答指示消息中是否存在该UE对应的索引号。
本发明实施例中,应答指示消息中包含有基站检测到数据的目标UE对应的索引号,第一解析单元2202可以从应答指示消息中解析是否存在该UE对应的索引号。当应答指示消息中存在该UE对应的索引号,可以说明基站检测到该UE发送的数据;当应答指示消息中不存在该UE对应的索引号,可以说明基站漏检了该UE发送的数据。此外,由于应答指示消息的数据长度为基站预定的固定长度,当基站检测到数据的UE数量超过了应答指示消息的数据长度,
则基站会舍去多余的UE,所以当应答指示消息中不存在该UE对应的索引号有可能是因为应答指示消息由于长度的限制而无法指示造成的,此时UE会认为基站未检测到数据而重新向基站发送数据。
作为一种可选的实施方式,应答指示消息用于指示该UE所属的应答分组中的目标UE对应的索引号外,还可以用于指示目标UE对应的索引号的标志位。

具体地,图22或图23所示的用户设备可以实施本发明结合图11或图12介绍的数据传输的应答指示方法实施例中的部分或全部流程。
