参考图1,为本发明实施例一提供的一种数据传输方法的实现流程图,其中,所述方法可以适用于数据传输的终端,如在下行传输中对数据进行接收的终端或在上行传输中对数据进行发送的终端。
具体的,在本实施例中,所述方法可以包括以下步骤:
步骤101:接收基站下发的调度指令,所述调度指令携带位置识别码,所述调度指令用于调度一个或多个传输子帧。
其中,所述调度指令可以为单个指令,进而能够调度一个传输子帧,进行数据传输;或者,所述调度指令也可以为多个指令所组成的指令集合,进而能够调度多个传输子帧,进行数据传输。
需要说明的是,所述调度指令为基站生成并发送,由此,所述终端能够接收到所述调度指令。
步骤102:获得所述调度指令携带的位置识别码。
其中,所述位置识别码可以为所述调度指令中直接包含的信息码,也可以为所述调度指令所表征的信息码,由此,所述终端在接收到所述调度指令之后,获得所述调度指令所携带的位置识别码。
步骤103:依据所述位置识别码、所述调度指令所在的子帧、以及调度位置识别规则,确定传输子帧。
其中,所述调度识别规则中包括位置识别码、调度指令所在的子帧、以及传输子帧的对应关系。
具体的,所述调度位置识别规则包括:位置识别码所能够表征的调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系的信息规则,由此,本实施例中在得到所述调度指令所携带的位置识别码之后,基于这一调度位置识别规则,识别出所述位置识别码所表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系,进而再利用所述调度指令所在的子帧的位置及这个位置对应关系,确定需要找到的传输子帧。
需要说明的是,所述调度位置识别规则为所述基站与所述终端之间进行协议商定的识别规则,也就是说,所述调度位置识别规则是所述基站预先发送给所述终端的,由此所述基站与所述终端之间能够基于一致的协议进行数据传输。
步骤104:通过所述传输子帧传输数据。
具体的,本实施例中利用所述传输子帧进行数据接收或进行数据发送,例如,在下行传输中,所述终端利用所述传输子帧进行数据接收;在上行传输中,所述终端利用所述传输子帧进行数据发送。
由上述方案可知,本发明实施例一提供的一种数据传输方法,通过在接收到基站下发的调度指令之后,获得调度指令所携带的位置识别码,进而基于位置识别码、调度指令所在子帧及传输子帧之间的位置关系,也就是调度位置识别规则来找到传输子帧,由此再通过传输子帧进行数据传输,实现跨子帧的数据传输,实现本实施例目的。
需要说明的是,所述调度指令为单个指令时,所述调度指令中携带一个位置识别码,本实施例中,在终端一方接收到调度指令之后,获得该调度指令所携带的位置识别码,进而基于所述位置识别码、所述调度指令所在的子帧以及所述调度位置识别规则,来确定传输子帧,进而通过该传输子帧进行数据传输,包括上行传输中的数据发送或者下行传输中的数据接收,实现本 发明目的。
另外,所述调度指令为多个时,这些多个调度指令作为一个指令集合以联合编码的形式被终端接收,也就是说,所述基站将这些多个调度指令进行联合编码之后,得到一个指令集合,进而将联合编码的形式的指令集合发送给终端。其中,所述终端接收到的指令集合的多个调度指令中,每个所述调度指令都会携带一个位置识别码,每个所述位置识别码可以相同的也可以是不同的,进而本发明中所述终端在接收到含有多个调度指令的指令集合之后,首先对该联合编码的这些调度指令进行解码,得到每个独立的调度指令,利用这些多个调度指令,实现多个传输子帧的跨子帧调度,进行多子帧的数据传输,包括上行传输中的数据发送或者下行传输中的数据接收,实现本发明目的。
具体的,参考图2,为本发明实施例二提供的一种数据传输方法的实现流程图,其中,所述方法可以包括以下步骤:
步骤201:接收基站通过目标信令通道下发的所述调度位置识别规则。
其中,所述目标信令通道为RRC、MAC CE或物理层的通道。也就是说,在所述终端一方,本实施例预先接收基站通过RRC、MAC CE或物理层等通道下发的所述调度位置识别规则。
步骤202:接收基站下发的指令集合,所述指令集合包括多个调度指令,所述多个调度指令以联合编码形式存在,且每个所述调度指令中携带一个位置识别码,每个所述调度指令用于调度一个传输子帧。
具体的,所述步骤202中,所述终端接收到联合编码形式存在的指令集合之后,需要对所述联合编码的指令集合进行解码,进而才能得到每个所述调度指令。
步骤203:获得每个所述调度指令携带的位置识别码。
步骤204:依据每个所述调度指令携带的位置识别码、相应的调度指令所在的子帧、以及所述调度位置识别规则,确定每个所述调度指令所携带的位置识别码所对应的传输子帧。
其中,所述调度位置识别规则中包括:位置识别码、调度指令所在的子 帧、以及传输子帧的对应关系。
具体的,所述调度位置识别规则包括:每个位置识别码所能够表征的调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系的信息规则,由此,本实施例中在得到每个所述位置识别码之后,基于这一规则,识别出每个所述位置识别码所表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系,进而再利用每个所述调度指令所在的子帧的位置及相应的位置对应关系,确定需要找到的传输子帧。
步骤205:通过确定的多个所述传输子帧传输数据。
具体的,本实施例中利用多个所述传输子帧进行数据接收或进行数据发送,例如,在下行传输中,所述终端利用多个所述传输子帧进行数据接收;在上行传输中,所述终端利用多个所述传输子帧进行数据发送。
由上述方案可知,本发明实施例二提供的一种数据传输方法,通过在接收到基站下发的包含多个调度指令的指令集合之后,对指令集合进行解码,得到每个独立的调度指令,由此获得每个调度指令所携带的位置识别码,进而基于位置识别码、调度指令所在子帧及传输子帧之间的位置关系,也就是预先从基站接收到的调度位置识别规则来找到传输子帧,由此再通过传输子帧进行数据传输,实现多子帧的跨子帧的数据传输,实现本实施例目的。
基于前述实施例,所述位置识别码可以为所述调度指令中直接包含的信息码,也可以为所述调度指令中所表征的信息码,以下对所述位置识别码的存在形式进行具体说明:
一种实现方式中,所述位置识别码是位于所述调度指令的起始位置或结束位置的信息域,所述位置识别码的长度至少是一个比特位,且所述位置识别码的长度固定,相应的,本实施例在获得所述位置识别码时,是直接从所述调度指令的起始位置或结束位置的信息域上直接获得所述位置识别码。
具体的,所述位置识别码在所述调度指令中的位置是固定的,且该位置识别码中的比特位长度固定,要么在起始位置上,要么在结束位置上,由此,在终端接收到所述调度指令之后,能够直接在该位置上获得所述位置识别码,进而依据所述位置识别码、所述调度指令所在的子帧,以及调度位置识 别规则,确定传输子帧,通过所述传输子帧传输数据,进而实现跨子帧调度的数据传输。
在具体实现中,所述调度位置识别规则中含有能够表征所述位置识别码如何获得的信息,诸如所述位置识别码在调度指令中的位置信息,如在起始位置或结束位置等,以及比特位长度等信息,如:所述调度位置识别规则中包括:位置识别码位于所述调度指令的起始位置、以及位置识别码的比特位长度等;或者,所述调度位置识别规则中包括:位置识别码位于所述调度指令的结束、以及位置识别码的比特位长度等。由此,所述终端在接收到所述调度指令之后能够基于这些信息获得所述位置识别码,进而基于位置识别码、调度指令所在的子帧以及调度位置识别规则,确定传输子帧,从而通过确定的传输子帧来进行数据传输。
需要说明的是,所述位置识别码中的比特位长度与所述调度指令最大所能够调度的子帧的数量相关。例如,所述调度指令最大可以调度的子帧个数是8个,那么所述位置识别码中的比特位长度是3,即所述位置识别码中有3个比特。而所述位置识别码中的比特值能够用以表征传输子帧与所述调度指令所在的子帧之间的位置对应关系,如,以所述调度指令所在的子帧为基准,该子帧、该子帧之后的下一个子帧、该子帧之后的第二个子帧、。。。、该子帧之后的第七个子帧,等等。
如下表1中所述调度位置识别规则的示例所示,所述调度指令最大可以调度的子帧的数目为5,那么所述位置识别码的长度是3个比特(5不超过8个,但大于4),如表1所示:
表1,调度位置识别规则
Figure PCTCN2016097166-appb-000001
Figure PCTCN2016097166-appb-000002
需要说明的是,上述表格中的被调度子帧的位置表示只是其中一个示例,基于同样的道理,上述被调度的子帧位置可以是其他的子帧位置。
例如,在终端一方,接收到调度位置识别规则如表1所示以及一个调度指令之后,对该调度指令上的固定位置上,如起始位置或结束位置上获得3个比特位的位置识别码,如码010,由此,根据表1,确定所述调度指令所在的子帧之后的第二个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输;或者所述位置信息码为100时,根据表1,确定所述调度指令所在的子帧之后的第四个可用的子帧为该调度指令所需要使用的传输子帧,进而通过该传输子帧进行数据传输。
而在终端接收到调度位置识别规则以及多个调度指令以联合编码形式所组成的指令集合之后,首先对该指令集合进行解码,进而得到每个独立的调度指令,如调度指令a1和a2,再在每个调度指令上的固定位置上,如起始位置或固定位置上获得的3个比特位的位置识别码,如在调度指令a1的起始位置上获得3个比特位的位置识别码:010,在调度指令a2的起始位置上获得3个比特位的位置识别码:011,根据表1,确定调度指令a1所在的 子帧之后的第二个可用的子帧为调度指令a1所需要使用的传输子帧,并确定调度指令a2所在的子帧之后的第三个可用的子帧为调度指令a2所需要使用的传输子帧,进而通过这两个传输子帧进行相应的数据传输。
另一种实现方式中,所述位置识别码是对所述调度指令经过CRC加扰的加扰结果进行加扰的正交序列码。也就是说,终端所接收到的基站所发送的调度指令为:初始的调度指令经过一次CRC加扰之后,利用正交序列码对该CRC加扰结果再进行一次加扰所得到的调度指令,而该正交序列码能够保证传输子帧与所述调度指令所在的子帧之间的位置对应关系。
在具体实现中,所述调度位置识别规则中含有能够表征所述位置识别码如何获得的信息,如对所述调度指令进行相应的处理,进而得到该调度指令所携带的位置识别码。由此,在终端一方,本实施例在接收到调度指令之后,基于所述调度位置识别规则对所述调度指令进行相应的处理操作,进而知道该调度指令被基站生成过程中所使用的正交序列码,即为位置识别码,进而基于位置识别码、调度指令所在的子帧以及调度位置识别规则,确定传输子帧,从而通过确定的传输子帧来进行数据传输。
在本实施例中,设置多个正交序列码组成一个正交序列组,该正交序列组中正交序列码的个数与所述调度指令所能够调度的子帧的数目相关,比如最大可以调度的子帧的个数为5个,那么该正交序列组中至少有8个正交序列码,如下表2中所示,每个所述正交序列码表征传输子帧与所述调度指令所在的子帧之间的位置对应关系,如以调度指令所在的子帧为基准,该子帧、该子帧之后的下一个子帧、该子帧之后的第二个子帧、。。。、该子帧之后的第七个子帧,等等。
表2,调度位置识别规则

Figure PCTCN2016097166-appb-000004
需要说明的是,上述表格中的被调度子帧的位置表示只是其中一个示例,基于同样的道理,上述被调度的子帧位置可以是其他的子帧位置。
例如,在终端一方,接收到调度位置识别规则如表2所示以及一个调度指令之后,对所述调度指令进行相应处理操作,以得到该调度指令被基站生成过程中所使用的正交序列码,即为位置识别码,如正交序列2,由此,根据表2,确定所述调度指令所在的子帧之后的第一个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输;或者所述位置信息码为正交序列4,由此,根据表2,确定所述调度指令所在的子帧之后的第三个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输。
而在终端接收到调度位置识别规则以及多个调度指令以联合编码形式所组成的指令集合之后,首先对该指令集合进行解码,进而得到每个独立的调度指令,如调度指令b1、b2及b3,再对每个调度指令进行相应处理操作,以得到每个调度指令被基站生成过程中所使用的正交序列码,如调度指令b1在生成时所使用的正交序列2、调度指令b2在生成时所使用的正交序列3、调度指令b3在生成时所使用的正交序列4,根据表2,确定调度指令b1所在的子帧之后的第一个可用的子帧为调度指令b1所需要使用的传输子帧,确定调度指令b2所在的子帧之后的第二个可用的子帧为调度指令b2所需要使用的传输子帧,确定调度指令b3所在的子帧之后的第三个可用的子帧为 调度指令b3所需要使用的传输子帧,进而通过这三个传输子帧进行相应的数据传输。
此外,本发明还提供了一种数据传输方法,其中,所述方法可以适用于数据传输的基站,如在下行传输中指示所述终端对数据进行接收的基站;或在上行传输中指示所述终端对数据进行发送的基站。
在本实施例中,所述方法可以包括以下步骤:
生成调度指令的步骤,以及将所述调度指令发送到终端的步骤。
其中,在生成调度指令的步骤中,具体的,所述调度指令携带位置识别码,所述调度指令用于调度一个或多个传输子帧,也就是说,所述调度指令可以为单个,进而能够调度一个传输子帧,进行数据传输;或者,所述调度指令也可以为多个指令所组成的指令集合,进而能够调度多个传输子帧,进行数据传输。
而在将所述调度指令发送到终端的步骤中,所述调度指令中所携带的位置识别码可以为:所述调度指令中直接包含的信息码,也可以为所述调度指令所表征的信息码,由此,所述终端在接收到所述调度指令之后,所述终端获得所述调度指令中所携带的位置识别码,进而依据所述位置识别码、所述调度指令所在的子帧,以及所述调度位置识别规则,确定传输子帧,再通过所述传输子帧传输数据。
其中,所述调度位置识别规则中包括位置识别码、调度指令所在的子帧、以及传输子帧的对应关系。在具体实现中,所述调度位置识别规则包括:所述位置识别码所能够表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系的信息规则,由此,在所述基站将所述调度指令发送到所述终端之后,所述终端在得到所述位置识别码之后,基于这一调度位置识别规则,识别出所述位置识别码所表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系,进而再利用所述调度指令所在的子帧的位置及这个位置对应关系,确定需要找到的传输子帧。
需要说明的是,所述调度位置识别规则为基站与终端之间进行协议商定的识别规则,也就是说,所述调度位置识别规则是所述基站预先发送给终端 的,由此基站与终端之间能够基于一致的协议进行数据传输。
其中,所述调度指令为单个指令时,所述调度指令携带一个位置识别码,本实施例中,基站将生成的调度指令发送到终端,所述终端接收到调度指令之后,终端获得该位置识别码,进而基于所述位置识别码、所述调度指令所在的子帧以及所述调度位置识别规则,来确定传输子帧,进而通过该传输子帧进行数据传输,包括上行传输中的数据发送或者下行传输中的数据接收,实现本发明目的。
另外,所述调度指令为多个时,这些多个调度指令作为一个指令一个以联合编码的形式由基站发送给终端,每个所述调度指令中携带一个位置识别码,每个所述位置识别码可以是相同的也可以是不同的,进而终端在接收到这些多个调度指令之后,首先对该联合编码这些调度指令进行解码,得到每个独立的调度指令,利用这些多个调度指令,实现多个传输子帧的跨子帧调度,进行多子帧的数据传输,包括上行传输中的数据发送或者下行传输中的数据接收,实现本发明目的。
具体的,参考图3,为本发明实施例三提供的一种数据传输方法的实现流程图,其中,所述方法可以包括以下步骤:
步骤301:通过目标信令通道下发的所述调度位置识别规则。
其中,所述目标信令通道为RRC、MAC CE或物理层的通道。也就是说,在所述基站一方,本实施例预先通过RRC、MAC CE或物理层等通道下发所述调度位置识别规则到所述终端一方。
步骤302:生成调度指令,所述调度指令为多个,多个调度指令以联合编码的形式组成指令集合,且每个所述调度指令中携带一个位置识别码,每个所述调度指令用于调度一个传输子帧。
具体的,本实施例中对初始的多个调度指令进行联合编码,得到指令集合,而每个所述调度指令中携带一个位置识别码,每个所述调度指令用于调度一个传输子帧。
步骤303:将包含多个调度指令的指令集合发送到终端。
其中,每个所述调度指令中所携带的位置识别码可以为:所述调度指令 中直接包含的信息码,也可以为所述调度指令所表征的信息码,由此,所述终端在接收到指令集合之后,首先对指令集合进行解码,得到每个独立的调度指令,在获得每个所述调度指令所携带的位置识别码,进而依据每个所述位置识别码、相应的所述调度指令所在的子帧、以及调度位置识别规则,确定传输子帧,再通过每个所述传输子帧传输数据,需要说明的是,每个所述传输子帧不同。
由上述方案可知,本发明实施例三提供的一种数据传输方法,通过基站在每个调度指令中携带一个位置识别码,进而将这些多个调度指令进行联合编码,得到一个指令集合,再将指令集合发送到终端中,由终端在获得指令集合之后,首先对指令集合进行解码,得到每个独立的调度指令,由此获得每个调度指令所携带的位置识别码,进而基于位置识别码、调度指令所在子帧及传输子帧之间的位置关系,也就是预先从基站接收到的调度位置识别规则来找到传输子帧,由此再通过传输子帧进行数据传输,实现多子帧的跨子帧的数据传输,实现本实施例目的。
基于前述实施例,所述位置识别码可以为所述调度指令中直接包含的信息码,也可以为所述调度指令中所表征的信息码。
具体的,所述位置识别码是位于所述调度指令的起始位置或结束位置的信息域,所述位置识别码的长度至少是一个比特位,且所述位置识别码的长度固定,且所述位置识别码中的比特位长度与所述调度指令最大所能够调度的子帧的数量相关。如表1中所述调度位置识别规则的示例所示,所述调度指令最大可以调度的子帧的数目为5,那么所述位置识别码的长度是3个比特(5不超过8个,但大于4)。
例如,在基站一方,在一个调度指令的起始位置或结束位置上添加位置识别码010,由此,在终端一方接收到调度位置识别规则如表1所示以及这个调度指令之后,对该调度指令上的相应位置上获得3个比特位的位置识别码,如码010,由此,根据表1,确定所述调度指令所在的子帧之后的第二个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输;在基站一方,在一个调度指令的起始位置或结束位置上添加位置识别码100,由此,在终 端一方接收到调度位置识别规则如表1所示以及这个调度指令之后,对该调度指令上的相应位置上3个比特位的位置识别码100,根据表1,确定所述调度指令所在的子帧之后的第四个可用的子帧为该调度指令所需要使用的传输子帧,进而通过该传输子帧进行数据传输。
再如,在基站一方,在调度指令a1的起始位置上添加位置识别码010,在调度指令a2的起始位置上添加位置识别码011,基站将这两个调度指令进行联合编码,得到一个指令集合发送给终端,在终端接收到调度位置识别规则以及这两个调度指令以联合编码形式所组成的指令集合之后,首先对该指令集合进行解码,进而得到每个独立的调度指令:调度指令a1和a2,再在每个调度指令上的相应位置上获得的3个比特位的位置识别码,如在调度指令a1的起始位置上获得3个比特位的位置识别码:010,在调度指令a2的起始位置上获得3个比特位的位置识别码:011,根据表1,确定调度指令a1所在的子帧之后的第二个可用的子帧为调度指令a1所需要使用的传输子帧,并确定调度指令a2所在的子帧之后的第三个可用的子帧为调度指令a2所需要使用的传输子帧,进而通过这两个传输子帧进行相应的数据传输。

具体的,所述调度位置识别规则包括:每个位置识别码所能够表征的调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系的信息规则,由此,本实施例中在得到每个所述位置识别码之后,基于这一规则,识别出每个所述位置识别码所表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系,进而再利用每个所述调度指令所在的子帧的位置及相应的位置对应关系,确定需要找到的传输子帧。

具体的,本实施例中利用多个所述传输子帧进行数据接收或进行数据发送,例如,在下行传输中,所述终端利用多个所述传输子帧进行数据接收;在上行传输中,所述终端利用多个所述传输子帧进行数据发送。
由上述方案可知,本发明实施例五提供的一种终端,通过在接收到基站下发的包含多个调度指令的指令集合之后,对指令集合进行解码,得到每个独立的调度指令,由此获得每个调度指令所携带的位置识别码,进而基于位置识别码、调度指令所在子帧及传输子帧之间的位置关系,也就是预先从基站接收到的调度位置识别规则来找到传输子帧,由此再通过传输子帧进行数据传输,实现多子帧的跨子帧的数据传输,实现本实施例目的。
基于前述实施例,所述位置识别码可以为所述调度指令中直接包含的信息码,也可以为所述调度指令中所表征的信息码,以下对所述位置识别码的存在形式进行具体说明:
一种实现方式中,所述位置识别码是位于所述调度指令的起始位置或结束位置的信息域,所述位置识别码的长度至少是一个比特位,且所述位置识别码的长度固定,相应的,本实施例在获得所述位置识别码时,是直接从所述调度指令的起始位置或结束位置的信息域上直接获得所述位置识别码。
具体的,所述位置识别码在所述调度指令中的位置是固定的,且该位置识别码中的比特位长度固定,要么在起始位置上,要么在结束位置上,由此,在终端接收到所述调度指令之后,能够直接在该位置上获得所述位置识别码,进而依据所述位置识别码、所述调度指令所在的子帧,以及调度位置识别规则,确定传输子帧,通过所述传输子帧传输数据,进而实现跨子帧调度的数据传输。
在具体实现中,所述调度位置识别规则中含有能够表征所述位置识别码如何获得的信息,诸如所述位置识别码在调度指令中的位置信息,如在起始位置或结束位置等,以及比特位长度等信息,如:所述调度位置识别规则中包括:位置识别码位于所述调度指令的起始位置、以及位置识别码的比特位长度等;或者,所述调度位置识别规则中包括:位置识别码位于所述调度指令的结束、以及位置识别码的比特位长度等。由此,所述终端在接收到所述调度指令之后能够基于这些信息获得所述位置识别码,进而基于位置识别码、调度指令所在的子帧以及调度位置识别规则,确定传输子帧,从而通过确定的传输子帧来进行数据传输。
需要说明的是,所述位置识别码中的比特位长度与所述调度指令最大所能够调度的子帧的数量相关。例如,所述调度指令最大可以调度的子帧个数是8个,那么所述位置识别码中的比特位长度是3,即所述位置识别码中有3个比特。而所述位置识别码中的比特值能够用以表征传输子帧与所述调度指令所在的子帧之间的位置对应关系,如,以所述调度指令所在的子帧为基准,该子帧、该子帧之后的下一个子帧、该子帧之后的第二个子帧、。。。、该 子帧之后的第七个子帧,等等。
另一种实现方式中,所述位置识别码是对所述调度指令经过CRC加扰的加扰结果进行加扰的正交序列码。也就是说,终端所接收到的基站所发送的调度指令为:初始的调度指令经过一次CRC加扰之后,利用正交序列码对该CRC加扰结果再进行一次加扰所得到的调度指令,而该正交序列码能够保证传输子帧与所述调度指令所在的子帧之间的位置对应关系。
在具体实现中,所述调度位置识别规则中含有能够表征所述位置识别码如何获得的信息,如对所述调度指令进行相应的处理,进而得到该调度指令所携带的位置识别码。由此,在终端一方,本实施例在接收到调度指令之后,基于所述调度位置识别规则对所述调度指令进行相应的处理操作,进而知道该调度指令被基站生成过程中所使用的正交序列码,即为位置识别码,进而基于位置识别码、调度指令所在的子帧以及调度位置识别规则,确定传输子帧,从而通过确定的传输子帧来进行数据传输。
在本实施例中,设置多个正交序列码组成一个正交序列组,该正交序列组中正交序列码的个数与所述调度指令所能够调度的子帧的数目相关,比如最大可以调度的子帧的个数为5个,那么该正交序列组中至少有8个正交序列码,如表2中所示,每个所述正交序列码表征传输子帧与所述调度指令所在的子帧之间的位置对应关系,如以调度指令所在的子帧为基准,该子帧、该子帧之后的下一个子帧、该子帧之后的第二个子帧、。。。、该子帧之后的第七个子帧,等等。
此外,本发明还提供了一种基站,权重,所述基站为用于数据传输的基站,如在下行传输中指示所述终端对数据进行接收的基站;或在上行传输中指示所述终端对数据进行发送的基站。
在本实施例中,所述基站可以用于
生成调度指令,并将所述调度指令发送到终端。
其中,所述基站所生成的调度指令中携带位置识别码,所述调度指令用于调度一个或多个传输子帧,也就是说,所述调度指令可以为单个,进而能够调度一个传输子帧,进行数据传输;或者,所述调度指令也可以为多个指 令所组成的指令集合,进而能够调度多个传输子帧,进行数据传输。
而所述调度指令中所携带的位置识别码可以为:所述调度指令中直接包含的信息码,也可以为所述调度指令所表征的信息码,由此,所述终端在接收到所述调度指令之后,所述终端获得所述调度指令中所携带的位置识别码,进而依据所述位置识别码、所述调度指令所在的子帧,以及所述调度位置识别规则,确定传输子帧,所述调度识别规则中包括所述位置识别码、所述调度指令所在的子帧、以及所述传输子帧的对应关系,再通过所述传输子帧传输数据。
其中,所述调度位置识别规则中包括位置识别码、调度指令所在的子帧、以及传输子帧的对应关系。在具体实现中,所述调度位置识别规则包括:所述位置识别码所能够表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系的信息规则,由此,在所述基站讲所述调度指令发送到所述终端之后,所述终端在得到所述位置识别码之后,基于这一调度位置识别规则,识别出所述位置识别码所表征的所述调度指令所在的子帧与需要找到的传输子帧之间的位置对应关系,进而再利用所述调度指令所在的子帧的位置及这个位置对应关系,确定需要找到的传输子帧。
需要说明的是,所述调度位置识别规则为基站与终端之间进行协议商定的识别规则,也就是说,所述调度位置识别规则是所述基站预先发送给终端的,由此基站与终端之间能够基于一致的协议进行数据传输。
其中,所述调度指令为单个指令时,所述调度指令携带一个位置识别码,本实施例中,基站将生成的调度指令发送到终端,所述终端接收到调度指令之后,终端获得该位置识别码,进而基于所述位置识别码、所述调度指令所在的子帧以及所述调度位置识别规则,来确定传输子帧,进而通过该传输子帧进行数据传输,包括上行传输中的数据发送或者下行传输中的数据接收,实现本发明目的。
另外,所述调度指令为多个时,这些多个调度指令作为一个指令一个以联合编码的形式由基站发送给终端,每个所述调度指令中携带一个位置识别码,每个所述位置识别码可以是相同的也可以是不同的,进而终端在接收到 这些多个调度指令之后,首先对该联合编码这些调度指令进行解码,得到每个独立的调度指令,利用这些多个调度指令,实现多个传输子帧的跨子帧调度,进行多子帧的数据传输,包括上行传输中的数据发送或者下行传输中的数据接收,实现本发明目的。
具体的,参考图6,为本发明实施例六提供的一种基站的结构示意图,其中,所述基站可以包括以下结构:
规则发送单元601,设置为通过目标信令通道下向终端发送所述调度位置识别规则。
其中,所述目标信令通道为RRC、MAC CE或物理层的通道。也就是说,在所述基站一方,本实施例预先通过RRC、MAC CE或物理层等通道下发所述调度位置识别规则到所述终端一方。
指令生成单元602,设置为生成调度指令,所述调度指令为多个,多个调度指令以联合编码的形式组成指令集合,且每个所述调度指令中携带一个位置识别码,每个所述调度指令用于调度一个传输子帧。
具体的,本实施例中,所述指令生成单元802对初始的多个调度指令进行联合编码,得到指令集合,而每个所述调度指令中携带一个位置识别码,每个所述调度指令用于调度一个传输子帧。
指令发送单元603,设置为将所述调度指令发送到终端。
其中,每个所述调度指令中所携带的位置识别码可以为:所述调度指令中直接包含的信息码,也可以为所述调度指令所表征的信息码,由此,所述终端在接收到指令集合之后,首先对指令集合进行解码,得到每个独立的调度指令,在获得每个所述调度指令所携带的位置识别码,进而依据每个所述位置识别码、相应的所述调度指令所在的子帧,以及调度位置识别规则,确定传输子帧,再通过每个所述传输子帧传输数据,需要说明的是,每个所述传输子帧不同。
由上述方案可知,本发明实施例六提供的一种基站,通过基站在每个调度指令中携带一个位置识别码,进而将这些多个调度指令进行联合编码,得到一个指令集合,再将指令集合发送到终端中,由终端在获得指令集合之后, 首先对指令集合进行解码,得到每个独立的调度指令,由此获得每个调度指令所携带的位置识别码,进而基于位置识别码、调度指令所在子帧及传输子帧之间的位置关系,也就是预先从基站接收到的调度位置识别规则来找到传输子帧,由此再通过传输子帧进行数据传输,实现多子帧的跨子帧的数据传输,实现本实施例目的。
基于前述实施例,所述位置识别码可以为所述调度指令中直接包含的信息码,也可以为所述调度指令中所表征的信息码。

例如,在基站一方,在一个调度指令的起始位置或结束位置上添加位置识别码010,由此,在终端一方接收到调度位置识别规则如表1所示以及这个调度指令之后,对该调度指令上的相应位置上获得3个比特位的位置识别码,如码010,由此,根据表1,确定所述调度指令所在的子帧之后的第二个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输;在基站一方,在一个调度指令的起始位置或结束位置上添加位置识别码100,由此,在终端一方接收到调度位置识别规则如表1所示以及这个调度指令之后,对该调度指令上的相应位置上3个比特位的位置识别码100,根据表1,确定所述调度指令所在的子帧之后的第四个可用的子帧为该调度指令所需要使用的传输子帧,进而通过该传输子帧进行数据传输。
再如,在基站一方,在调度指令a1的起始位置上添加位置识别码010,在调度指令a2的起始位置上添加位置识别码011,基站将这两个调度指令进行联合编码,得到一个指令集合发送给终端,在终端接收到调度位置识别规则以及这两个调度指令以联合编码形式所组成的指令集合之后,首先对该指令集合进行解码,进而得到每个独立的调度指令:调度指令a1和a2,再在 每个调度指令上的相应位置上获得的3个比特位的位置识别码,如在调度指令a1的起始位置上获得3个比特位的位置识别码:010,在调度指令a2的起始位置上获得3个比特位的位置识别码:011,根据表1,确定调度指令a1所在的子帧之后的第二个可用的子帧为调度指令a1所需要使用的传输子帧,并确定调度指令a2所在的子帧之后的第三个可用的子帧为调度指令a2所需要使用的传输子帧,进而通过这两个传输子帧进行相应的数据传输。
另一种实现方式中,所述位置识别码是对所述调度指令经过CRC加扰的加扰结果进行加扰的正交序列码。在本实施例中,基站设置多个正交序列码组成一个正交序列组,该正交序列组中正交序列码的个数与所述调度指令所能够调度的子帧的数目相关,比如最大可以调度的子帧的个数为5个,那么该正交序列组中至少有8个正交序列码,如表2中所示,每个所述正交序列码表征传输子帧与所述调度指令所在的子帧之间的位置对应关系,如以调度指令所在的子帧为基准,该子帧、该子帧之后的下一个子帧、该子帧之后的第二个子帧、。。。、该子帧之后的第七个子帧,等等。
例如,在基站一方,对初始的调度指令进行CRC加扰的结果以正交序列码2进行加扰操作,并将加扰后的调度指令发送给终端,在终端一方,接收到调度位置识别规则如表2所示以及这个调度指令之后,对所述调度指令进行相应处理操作,以得到该调度指令被基站生成过程中所使用的正交序列码2,即为位置识别码,由此,根据表2,确定所述调度指令所在的子帧之后的第一个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输;或者,在基站一方,对初始的调度指令进行CRC加扰的结果以正交序列码4进行加扰操作,并将加扰后的调度指令发送给终端,在终端一方,接收到调度位置识别规则如表2所示以及这个调度指令之后,对所述调度指令进行相应处理操作,以得到该调度指令被基站生成过程中所使用的正交序列码4,即为位置识别码,由此,根据表2,确定所述调度指令所在的子帧之后的第三个可用的子帧为传输子帧,进而通过该传输子帧进行数据传输。
