Description

传输重传码本的方法及装置 技术领域
本发明涉及通信技术领域，尤其涉及一种传输重传码本的方法及装置。
背景技术
相关技术中，在5G(第5代移动通信系统)中提出以CBG(Code Block Group，码块组)为传输单位。CBG是比TB(Transmission Block，传输块)更小的数据单元单位。在混合自动重传请求(Hybrid Automatic Repeat reQuest，HARQ)场景中，需要针对CBG进行反馈，反馈ACK(确认)/NACK(非确认)。对于多个载波的HARQ重传，需要将多个CC(Component Carrier，成员载波)的重传信息进行有效的编码聚合，即生成重传码本(HARQ codebook)，以实现统一的将重传反馈信息进行上报。
对于非授权频段系统，用户设备(UE)需要遵循LBT(listen before talk)机制，即预先探测重传码本的时频资源是否空闲，如果空闲，则可上报重传码本。如果时频资源不空闲，则在下次探测时，是否要上传之前未上报的重传码本，以及如何上传之前未上报的重传码本，这是亟待解决的问题。

具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本发明相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本发明的一些方面相一致的装置和方法的例子。
相关技术中，对于非授权频段系统，也可采用HARQ技术，针对下行信息的接收情况，向基站反馈重传反馈信息，即ACK(确认)或NACK(非确认)。针对一个下行信息块，可上报一个相应的重传码本，该重传码本中的一个bit表示下行信息块中一个CBG(Code Block Group，码块组)的接收情况。该bit的值为1，表示ACK，值为0表示NACK。其中，CBG是TB(Transmission Block，传输块)中更小的数据单元单位。但是，非授权频段系统需要遵循LBT(listen before talk，先听后说)机制，即在上报重传码本之前，需要探测是否有足够空闲的用于上报重传码本的时频资源，如果没有，则本次放弃上报重传码本。在下次探测时，是否要上传之前未上报的重传码本，以及如何上传之前未上报的重传码本，这是亟待解决的问题。
为解决所述问题，本实施例提供了将多个重传码本合并的方案。将多个应上报而未上报的重传码本合并为一个重传码本，即合并重传码本。这样，该合并重传码本包含了多个重传码本所表示的重传反馈信息，并且节省了重传反馈信息所占用的网络资源，更容易及时上报。
图1是根据一示例性实施例示出的一种传输重传码本的方法的流程图，该传输重传码本的方法用于用户设备，其中，用户设备可以是移动电话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图1所示，该方法包括以下步骤101-103。
在步骤101中，针对一个信息块生成一个重传码本；所述重传码本中的一个比特位(bit)表示下行的一个码块组(CBG)是否接收成功。
在步骤102中，针对一个信道占用时间(COT)，将多个信息块对应的多个重传码本合并为一个合并重传码本，其中一个COT对应多个信息块，一个信息块对应至少一个传输块，一个传输块对应至少一个CBG；一个信息块包括一次物理下行控制信道和一次物理下行数据信道传输。
在步骤103中，向基站发送所述合并重传码本。
本实施例中将多个应上报而未上报的重传码本所对应的下行信息用一个信道占用时间(Channel Occupancy Time，COT)来表示。COT可以是MCOT(最大信道占用时间)。
如图2A所示，DL表示下行链路，G表示空隙，UL表示上行链路，DL包括物理下行控制 信道和物理下行数据信道。用户设备在201处接收到下行信息。需要在202处上报重传反馈信息，即重传码本，以反馈201处是否成功接收。但是，需要预先探测202的时频资源是否空闲，如果空闲，则上报关于201的重传码本1；如果不空闲，在放弃在202上报重传码本1。然后，探测204的时频资源是否空闲，如果空闲，则需要上报重传码本1和关于203的重传码本2。
当然，也可以按照系统的配置，不进行202的探测，而是在201后生成重传码本1。然后探测204的时频资源是否空闲，如果空闲，则需要上报重传码本1和关于203的重传码本2。
无论是上述哪种情况，在需要上报重传码本1和重传码本2时，本实施例将重传码本1和重传码本2合并为合并重传码本，即合并为一个重传码本。该合并重传码本反应了201和203的接收情况。并且，该合并重传码本占用的网络资源更少，在探测时更容易成功，上报几率更大。
本实施例可以在探测到204的时频资源是否空闲时，也就是可以上报重传码本时，将重传码本1和重传码本2合并。如果204的时频资源不空闲，则不合并重传码本1和重传码本2，待206空闲时，一次性合并重传码本1、2和3。或者，如果204的时频资源不空闲，也合并重传码本1和重传码本2，得到合并重传码本1，待206空闲时，将合并重传码本1和重传码本3合并，得到合并重传码本2。
如图2B所示，211、212和213三个信息块对应的下行信息，在214对应的上行链路中反馈合并重传码本，该合并重传码本为211、212和213所对应的三个重传码本合并后的结果。
在一个实施例中，所述重传码本对应为矩阵结构；最大CBG数和所述信息块的总数(total)下行链路分配索引(DAI)为所述矩阵的行数和列数；其中，最大CBG数是指所述信息块中的各个传输块对应的CBG数中的最大值。
本实施例中，重传码本实际是字符串形式，但是其反应的下行链路可以对应为矩阵结构。矩阵中的一个有效的坐标点对应字符串中的1bit，也对应着一个下行CBG。本实施例利用最大CBG数和total DAI来定义该矩阵的行和列，矩阵中的一列对应一个TB，该列中的各行对应该TB中的各个CBG。各TB按照频域由高到低，时域从小到大的顺序排列，这样的排列顺序符合DAI的计数和统计顺序。当然，也可以按照其它顺序排列，系统预先规定即可。其中，一个TB可以对应一个时隙(slot)。
本实施例采用这样的矩阵结构，便于生成重传码本，也便于重传码本的合并，以及方便基站对重传码本的解析。
在一个实施例中，所述步骤102包括：步骤A1和步骤A2。
在步骤A1中，针对一个信道占用时间(COT)，将多个信息块对应的多个重传码本，以矩阵(0,0)点对齐。
在步骤A2中，按bit进行与或计算，得到合并重传码本；其中，合并重传码本的行数和列数分别为多个重传码本中的行数和列数的最大值。
例如，参见图3,301表示重传码本1，为4×13的矩阵。302表示重传码本2，为2×10的矩阵。将301和302以左上角(0,0)点对齐。重合坐标点的bit进行与或计算。不重合的坐标点的bit保留原矩阵的值。得到合并后的303，即合并重传码本。从图3可知，合并后的303是4×13的矩阵。本实施例中合并重传码本的大小与重传码本1的大小相同，占用的网络资源较少。
例如，参见图4,401表示重传码本1，为4×13的矩阵。402表示重传码本2，为2×20的矩阵。将401和402以左上角(0,0)点对齐。重合坐标点的bit进行与或计算。不重合的坐标点的bit保留原矩阵的值。得到合并后的403，即合并重传码本。从图4可知，合并后的403是4×20的矩阵。
在一个实施例中，所述方法还包括：步骤B1。
在步骤B1中，将多个COT对应的多个合并重传码本合并为一个最终重传码本。
所述步骤103包括：步骤B2。
在步骤B2中，向基站发送所述最终重传码本。
本实施例中，一个COT对应一个合并重传码本。多个COT中，无论是否曾经上传了合并重传码本，都可以将多个合并重传码本合并为一个最终重传码本并上传。多个合并重传码本的合并，可以进一步节省重传反馈信息占用的网络资源。
用户设备可以自动针对未上传过的合并重传码本进行合并。或者，根据基站的指示，也可以针对已上传过的合并重传码本进行合并。
例如，参见图5A,501表示重传码本1，为4×13的矩阵。502表示重传码本2，为2×20的矩阵。将501和502以左上角(0,0)点对齐。重合坐标点的bit进行与或计算。不重合的坐标点的bit保留原矩阵的值。得到合并后的503，即合并重传码本1，是4×20的矩阵。503可以与504(合并重传码本2，8×10的矩阵)再次进行合并，得到505(最终重传码本),8×20的矩阵。
如图5B所示，多个COT中，每个COT的上行链路均可以上报一次合并重传码本。在最后一个COT的上行链路，可以上报最终重传码本。
在一个实施例中，所述信息块对应多个成员载波(Component Carrier，CC)。
例如，如图6所示，以8个CC为例，分别是CC0、CC1……CC7。每个CC上TB所包括的CBG的数量可能不同。图6中阴影表示有下行CBG传输，一个方块表示一个TB。方块中的数字表示计数(counter，或称序号)DAI/总数DAI，该数字也可以作为TB的标识，用户设备和基站均保存有该标识。图6所示的信息块对应的重传码本为4×13的矩阵，矩阵中的第一列对应图6中1/3所示的4个CBG，第二列对应图6中2/3所示的1个CBG，其它以此类推。
下面通过实施例详细介绍用户设备侧的实现过程。
图7是根据一示例性实施例示出的一种传输重传码本的方法的流程图，该传输重传码本的方法用于用户设备，其中，用户设备可以是移动电话，计算机，数字广播终端，消息收发设备，游戏控制台，平板设备，医疗设备，健身设备，个人数字助理等。如图7所示，该方 法包括以下步骤701-708。
在步骤701中，针对一个信息块生成一个重传码本；所述重传码本中的一个比特位(bit)表示下行的一个码块组(CBG)是否接收成功。
在步骤702中，检测是否有未上报的重传码本。如果没有，则继续步骤703；如果有，则继续步骤704。
在步骤703中，向基站发送所述重传码本。
在发送所述重传码本之前，需要探测是否有足够的空闲时频资源，如果有，则发送所述重传码本；如果没有，则保存该重传码本，以便进行步骤702中的检测。
在步骤704中，将多个未上报的重传码本合并为一个合并重传码本。
在步骤705中，检测是否有未上报的合并重传码本。如果没有，则继续步骤706；如果有，则继续步骤707。
在步骤706中，向基站发送所述合并重传码本。
在步骤707中，将多个未上报的合并重传码本合并为一个最终重传码本。
在步骤708中，向基站发送所述最终重传码本。
以上介绍了用户设备侧的实现过程，相应的，基站侧的实现过程也有改进。下面介绍基站侧的实现过程。
图8是根据一示例性实施例示出的一种传输重传码本的方法的流程图，该传输重传码本的方法用于基站等接入网设备。如图8所示，该方法包括以下步骤801-803。
在步骤801中，接收用户设备发送的合并重传码本，所述合并重传码本对应一个COT，一个COT对应多个信息块，一个信息块对应至少一个传输块，一个传输块对应至少一个CBG；一个信息块包括一次物理下行控制信道和一次物理下行数据信道传输。
在步骤802中，确定所述合并重传码本对应的多个信息块。
在步骤803中，确定所述合并重传码本中的各个bit在对应的各个所述信息块中对应的CBG。
本实施例中，由于合并重传码本是由多个重传码本合并而成，所以基站需要将合并重传码本对应到各个信息块，这样基站才能知道合并重传码本中的各个bit所表示的是各个所述信息块中的哪些CBG的接收情况。
在合并重传码本时采用的是与或计算，则，合并重传码本中的bit值为1，表示各个信息块中相应的CBG均接收成功，不需要重传。如果合并重传码本中的bit值为0，表示各个信息块中相应的CBG均接收失败，均需要重传。
例如，在合并时，重传码本1(对应信息块1)的(1,1)坐标点的值为1，重传码本2(对应信息块2)的(1,1)坐标点的值为0。与或计算后，合并重传码本1的(1,1)坐标点的值为0。基站接收到合并重传码本1后，将(1,1)坐标点对应到信息块1中的1个CBG1和信息块2中的1个CBG2，由于合并重传码本1的(1,1)坐标点的值为0，因此基站确定CBG1和CBG2均需要重传。
又如，继续图3所示的例子，基站接收到303。之前，基站在进行下行传输时，会记录计数DAI/总数DAI等相关信息，以及每个CC上的CBG数。虽然基站不一定生成重传码本，但是基站可以确定重传码本中的各bit所对应的CBG。并且，基站可以预先记录有未收到哪些信息块的重传码本。因此，基站可以知道303对应哪些信息块。以及，基站可以知道303中2×10的部分为重合区域，对应信息块1和信息块2。其余部分为非重合区域，对应信息块1。
在一个实施例中，所述步骤801包括：步骤C1。
在步骤C1中，接收用户设备发送的最终重传码本。
所述方法还包括：步骤C2。
在步骤C2中，确定所述最终重传码本对应的多个COT。
本实施例中，基站可以知道针对哪些COT是否收到过合并重传码本，如果有多个COT未收到过重传码本，那么步骤C1中收到的就是最终重传码本，需要对应到多个COT上。然后再对应到各个COT中的各个信息块，及对应到各个CBG。或者，基站曾经指示过用户设备上报最终重传码本，因此基站也可以知道步骤C1中收到的就是最终重传码本。
在一个实施例中，所述信息块对应多个成员载波。
下面通过实施例详细介绍基站侧的实现过程。
图9是根据一示例性实施例示出的一种传输重传码本的方法的流程图，该传输重传码本的方法用于基站等接入网设备。如图9所示，该方法包括以下步骤901-904。
在步骤901中，接收用户设备发送的最终重传码本。
在步骤902中，确定所述最终重传码本对应的多个COT。
在步骤903中，确定所述最终重传码本在各个COT中对应的多个信息块。
在步骤904中，确定所述最终重传码本中的各个bit在对应的各个所述信息块中对应的CBG。
下面结合用户设备侧和基站侧介绍实现过程。
图10是根据一示例性实施例示出的一种传输重传码本的方法的流程图。如图10所示，该方法包括以下步骤1001-1003。
在步骤1001中，用户设备针对一个信息块生成一个重传码本；所述重传码本中的一个比特位(bit)表示下行的一个码块组(CBG)是否接收成功。
在步骤1002中，用户设备针对一个信道占用时间(COT)，将多个信息块对应的多个重传码本合并为一个合并重传码本，其中一个COT对应多个信息块，一个信息块对应至少一个传输块，一个传输块对应至少一个CBG；一个信息块包括一次物理下行控制信道和一次物理下行数据信道传输。
在步骤1003中，用户设备向基站发送所述合并重传码本。
在步骤1004中，基站接收用户设备发送的合并重传码本。
在步骤1005中，基站确定所述合并重传码本对应的多个信息块。
在步骤1006中，基站确定所述合并重传码本中的各个bit在对应的各个所述信息块中对应的CBG。
以上实施例可以根据实际需要进行自由组合。
