技术领域
本公开涉及通信技术领域，尤其涉及一种信息传输的方法及装置。
背景技术
在机器类通信(Machine Type Communications，MTC)项目中，为了增强MTC设备在深衰场景下的覆盖，提出了对物理信道在多个子帧重复发送的方法。为了达到最大15dB的覆盖增强，重复次数可达几十次甚至上百次。目前，对于重复发送期间冗余版本如何确定尚无结论。
相关技术中，对于下行数据传输，编码单元对一个传输时间间隔(Transmission Time Interval，TTI)内到达的传输块进行处理，之后再经过物理信道处理后在相应的物理资源上进行传输，如图1所示，来自媒体接入控制(Media Access Control，MAC)的传输块经过传输块处理和物理信道处理之后，在各个子帧(例如：无线帧#M子帧#0、无线帧#M+1子帧#2、无线帧#M+2子帧#3)中传输，各TTI中传输块的处理是各自独立的。
其中，传输块处理流程中包括速率匹配，速率匹配过程包括子块交织、比特收集和比特选择，如图2所示，比特收集将经子块交织器处理的系统比特流、第一校验比特流和第二校验比特流进行级联，比特选择根据该子帧的冗余版本(RV＝0、RV＝2、RV＝3、RV＝1)选择输出比特流。对于下行数据传输而言，冗余版本是在下行控制信息DCI中指示的。
对于上行数据传输，存在单子帧传输和传输时间间隔绑定TTI bundling两种方式。对于单子帧传输，流程和下行数据传输基本类似，编码单元对于一个TTI内的传输块进行处理，之后再经过物理信道处理在相应的资源上进行传 输。各TTI中传输块的处理是各自独立的。
上行数据传输的冗余版本由MAC层的参数CURRENT_IRV确定，它用来指示冗余版本序列中的序号，每次混合自动重传请求(Hybrid Automatic Repeat Request，HARQ)传输(新传输或者重传)后CURRENT_IRV加1，且CURRENT_IRV模4，冗余版本序列为0，2，3，1。
上行TTI bundling是一种增强上行覆盖的传输方法，在多个连续子帧(TTI)发送一个传输块的不同冗余版本，即在多个连续TTI自动进行HARQ重传，期间不需ACK/NACK反馈，如图3所示，来自MAC的传输块经过循环冗余校验(Cyclic Redundancy Check，CRC)、信道编码和速率匹配之后，在多个连续TTI发送一个传输块的不同冗余版本，例如：图3中示出的每一传输块均发送四种冗余版本，分别为：RV＝0、RV＝2、RV＝3、RV＝1。
但是，为了尽可能减少重复次数，从而尽可能减轻由于重复带来的系统频谱效率下降，经过研究，发现跨子帧信道估计是一种有效的手段。所谓跨子帧信道估计，是指利用信道的相关性，基于连续的多个子帧内的参考信号进行联合信道估计，一种典型的处理方式是将多个子帧信道估计的结果进行加权平均。相应地，数据部分进行相干合并。相干合并的前提是在用来合并的多个子帧中的发送信号是相同的。
然而相关技术中下行数据传输每个TTI的处理是独立的，没有一个传输块在多个子帧中重复发送的机制；对于上行传输，TTI bundling机制可以实现一个传输块在多个子帧中重复发送，但冗余版本是随着子帧循环变化的，即相邻子帧的冗余版本不同。这就意味着发送的信号在子帧间经速率匹配后是不同的，从而导致接收端无法进行相干合并。
综上所述，相关技术中信息在多个子帧中重复发送时，冗余版本随子帧循环变化，相邻子帧的冗余版本不同，从而各个子帧经速率匹配后发送的信息也不相同，从而导致对端在用来相干合并的多个子帧上接收到的信息不同，无法进行相干合并，从而无法降低由于信息重复发送导致的系统频谱效率下降。
发明内容
本公开的一些实施例提供了一种信息传输的方法及装置，用以通过将多个连续子帧对应的冗余版本确定为同一冗余版本，使得多个连续子帧经速率匹配后发送的信息相同，对端能够对该多个连续子帧上发送的信息进行相干合并，降低由于信息重复发送导致的系统频谱效率下降。

具体实施方式
下面结合附图，对本公开的一些实施例提供的一种信息传输的方法及装置的具体实施方式进行详细地说明。
本公开的一些实施例提供一种信息传输的方法，如图4所示，该方法包括：
步骤402，当本端作为发送端时，本端确定需要在包含多个子帧的重复传输期间重复传输的信息；
步骤404，针对该重复传输期间的每一子帧，本端确定该子帧对应的冗余版本，并根据该子帧对应的冗余版本对信息经编码后的比特流进行速率匹配， 并将速率匹配后的比特流发送至对端，其中，存在多个连续子帧对应的冗余版本相同。
本公开的一些实施例提供的方法中，在根据每一子帧对应的冗余版本对信息经编码后的比特流进行速率匹配时，由于存在多个连续子帧对应的冗余版本相同，使得多个连续子帧经速率匹配后发送的信息也相同，对端能够对该多个连续子帧上发送的信息进行相干合并，与相关技术中各个子帧的冗余版本随子帧循环变化，速率匹配之后各个子帧中发送的信息不同，在对端无法进行相干合并相比，存在多个连续子帧对应的冗余版本相同，使得多个连续子帧经速率匹配后发送的信息也相同，对端能够对该多个连续子帧上发送的信息进行相干合并，降低由于信息重复发送导致的系统频谱效率下降。同时，由于重复传输期间存在多个连续子帧对应的冗余版本相同，整个重复传输期间可能存在多种不同的冗余版本，也即冗余版本在整个重复传输期间可以变化，从而实现增益冗余合并。
需要说明的是，本公开的一些实施例中在物理信道中传输的信息包括：传输块、数据和/或控制信息等，本端和对端均可以是网络侧设备(例如：基站)或用户设备，当然，当本端为网络侧设备时，对端为用户设备；当本端为用户设备时，对端为网络侧设备。
具体实施时，冗余版本的确定可以由物理层处理。优选地，信息(例如：传输块)经过信道编码后缓存在速率匹配模块中的比特收集模块中，比特选择模块根据确定的每个子帧的冗余版本进行比特选择。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，针对该重复传输期间的每一子帧，本端确定该子帧对应的冗余版本，包括：针对该重复传输期间的每一子帧，本端根据预设的至少一种冗余版本、以及至少一种冗余版本的使用规则，确定当前子帧对应的冗余版本。具体分为以下两种情况：
针对重复传输期间的第一个子帧，本端将初始冗余版本确定为该子帧对应的冗余版本，该初始冗余版本为至少一种冗余版本中的任意一种冗余版本；例如：预设的至少一种冗余版本包括：RV0、RV1、RV2、RV3＝0，2，3，1，预设的 初始冗余版本为RV2，则重复传输期间的第一个子帧的冗余版本为RV2＝3。
针对重复传输期间的第一个子帧之后的每一子帧，本端根据预设的至少一种冗余版本、至少一种冗余版本的使用先后顺序、每一冗余版本连续重复使用次数、上一子帧对应的冗余版本的连续重复使用次数，确定当前子帧对应的冗余版本。具体来说：
针对重复传输期间的第一个子帧之后的每一子帧，当上一子帧对应的冗余版本的连续重复使用次数小于该冗余版本连续重复使用次数时，确定该冗余版本为当前子帧对应的冗余版本；当上一子帧对应的冗余版本的连续重复使用次数等于该冗余版本连续重复使用次数时，根据至少一种冗余版本的使用先后顺序，确定使用顺序在该上一子帧对应的冗余版本之后相邻的冗余版本为当前子帧对应的冗余版本。
作为较为具体的实施例，至少一种冗余版本包括：RV0，RV1，…，RVN-1；至少一种冗余版本的使用先后顺序为RV0→RV1→…→RVN-1→RV0，也即至少一种冗余版本循环使用；初始冗余版本为RVM，M∈(0，1，...，N-1)；每一冗余版本连续重复使用次数为T，T∈(1，2，...，R)，R为重复传输期间包括的总的子帧个数，则第i次传输的冗余版本为RVn，
Figure PCTCN2016077682-appb-000001
i∈(0，1，...，R-1)，此实施例为使用当前子帧的传输次数确定每一子帧对应的冗余版本，当然，还可以根据上一子帧对应的冗余版本的连续重复使用次数确定当前子帧对应的冗余版本，具体来说：
当上一子帧对应的冗余版本的连续重复使用次数小于该冗余版本连续重复使用次数时，确定该冗余版本为当前子帧对应的冗余版本，当前子帧对应的冗余版本的连续重复使用次数加1；
当上一子帧对应的冗余版本的连续重复使用次数等于该冗余版本连续重复使用次数时，根据至少一种冗余版本的使用先后顺序，确定使用顺序在该上一子帧对应的冗余版本之后相邻的冗余版本为当前子帧对应的冗余版本，并将当前子帧对应的冗余版本的连续重复使用次数初始化为1。
具体实施时，每一冗余版本连续重复使用次数内多个连续子帧对应的冗余版本相同，使得多个连续子帧经速率匹配后发送的信息也相同，对端能够对该多个连续子帧上发送的信息进行相干合并，降低由于信息重复发送导致的系统频谱效率下降。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，在本端和对端中预先存储冗余版本图样信息，或者，由本端和对端中的网络侧一端确定冗余版本图样信息，并将冗余版本图样信息通知另一端的用户设备，其中，冗余版本图信息样包括：至少一种冗余版本以及至少一种冗余版本的使用先后顺序。
具体实施时，冗余版本图样可以根据协议约定预先存储在本端和对端中，也可以由本端和对端中网络侧一端可以通过高层信令(例如：RRC信令)、系统广播、下行控制信息(Downlink Control Information，DCI)等将冗余版本图样通知另一端的用户设备。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，由本端和对端确定初始冗余版本，或者，由本端确定的初始冗余版本通知所述对端。
具体实施时，初始冗余版本可以由本端和对端中的MAC层确定，也可以由本端确定初始冗余版本，并将该初始冗余版本通过高层信令(例如：RRC信令)、系统广播、DCI通知对端。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，在本端和对端中预先储存每一冗余版本连续重复使用次数，或者，由本端和对端中的网络侧一端确定每一冗余版本连续重复使用次数，并将每一冗余版本连续重复使用次数通知另一端的用户设备。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，该方法还包括：本端和对端中的网络侧一端通过下行控制信息DCI指示是否采用每一冗余版本连续重复使用次数，或者本端和对端根据预设规则确定是否采用每一冗余版本连续重复使用次数。
具体实施时，本端根据下行控制信息DCI指示或者预设规则确定每一冗余 版本连续重复使用次数，预设规则包括信息传输的码率是否大于或等于预设阈值、用户设备是否支持在重复传输期间改变冗余版本等。
需要说明的是，本端和对端中的网络侧一端通过下行控制信息DCI指示是否采样每一冗余版本连续重复使用次数，是指本端和对端中的网络侧一端通过下行控制信息DCI指示是否采用本端和对端中预先存储的每一冗余版本连续重复使用次数，或者本端和对端中的网络侧一端通过下行控制信息DCI指示是否采用网络侧一端预先配置并通知用户设备的每一冗余版本连续重复使用次数。具体来说：
本端和对端中的网络侧一端通过下行控制信息DCI指示是否采用每一冗余版本连续重复使用次数，具体包括：当本端通过下行控制信息DCI指示采用每一冗余版本连续重复使用次数时，每一冗余版本连续重复次数确定为本端和对端中预先存储的每一冗余版本连续重复使用次数，或者采用网络侧一端预先配置并通知用户设备的每一冗余版本连续重复使用次数；当本端通过下行控制信息DCI指示不采用每一冗余版本连续重复使用次数时，每一冗余版本连续重复次数确定为重复传输期间包括的子帧个数。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，本端和对端根据预设规则确定每一冗余版本连续重复使用次数，具体包括：本端和对端根据信息传输的码率确定每一冗余版本连续重复使用次数。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，本端和对端根据信息传输的码率确定每一冗余版本连续重复使用次数，具体包括：
当信息传输的码率大于或等于预设阈值时，每一冗余版本连续重复使用次数采用本端和对端中预先存储的每一冗余版本连续重复使用次数，或者采用网络侧一端预先配置并通知用户设备的每一冗余版本连续重复使用次数；
当信息传输的码率小于预设阈值时，每一冗余版本连续重复使用次数等于重复传输期间包括的子帧个数。
其中，预设阈值可以预先存储在本端和对端中，或者由本端和对端中的网络侧一端确定并通知另一端的用户设备，预设阈值可以采用默认值，也可以根 据实际情况具体设置，例如：预设阈值取值为9。
下面结合具体的实施例对本公开的一些实施例提供的信息传输的方法进行具体的说明。
根据本公开的一些实施例，以上行数据传输为例，冗余版本图样在协议中预先约定，假设协议中定义冗余版本图样为RV0，RV1，RV2，RV3＝0，2，3，1，也即四种冗余版本的使用顺序为RV0→RV1→RV2→RV3；每一冗余版本连续重复使用次数T也在协议中预先约定，假设在协议中定义T＝4。
具体地，以FDD为例，如图5A所示，假设用户设备UE接收到网络侧(例如：基站)的调度授权，为UE的一个上行传输块分配了从无线帧#M子帧#0开始的连续24个子帧的资源。
UE侧MAC层根据变量CURRENT_IRV确定此次传输的初始冗余版本RVM，假设RVM＝RV0＝0。如图5B所示，MAC层将传输块及CURRENT_IRV递交给物理层，物理层对传输块添加CRC以及进行信道编码，之后进行速率匹配。速率匹配模块中的比特收集模块缓存着子块交织后级联的数据。在重复传输期间的每个子帧，比特选择模块根据冗余版本图样、初始冗余版本、每一冗余版本连续重复使用次数以及当前的传输次数确定每个子帧对应的冗余版本，基于比特收集模块缓存的编码数据，根据确定的冗余版本选择相应的输出数据。
其中，第i次传输的冗余版本为RVn，
Figure PCTCN2016077682-appb-000002
i＝0，1，…，23
如图5C所示，第0至第3个子帧的冗余版本为RV0＝0；第4至第7个子帧的冗余版本为RV1＝2，第8至第11个子帧的冗余版本为RV2＝3，以此类推。
相应地，基站侧根据冗余版本图样、初始冗余版本、每一冗余版本连续重复使用次数以及当前的传输次数确定重复传输期间每个子帧对应的冗余版本依次为0，0，0，0，2，2，2，2，3，3，……，并按照确定每一子帧对应的冗余版本对重复期间各个子帧接收到的数据进行解速率匹配。
基站侧对于冗余版本相同的连续4个子帧可以进行相干合并，对于冗余版本不同的子帧则进行非相干合并。这样，一方面获得了跨子帧信道估计对信道 估计性能的改善，另一方面又可以改变重复传输期间的冗余版本实现增量冗余合并，在高码率传输时获得增量冗余合并的合并增益。
值得注意的是，对TDD而言，由于上下行子帧配置的存在，为一个传输块分配的多个子帧中在时间上可能是不连续的。仍然以本公开的一些实施例的参数为假设，以TDD为例，如图5D所示，UE接收到基站的调度授权，为UE的一个上行传输块分配了从无线帧#M子帧#0开始的连续24个上行子帧的资源。则第i次传输的冗余版本为RVn，
Figure PCTCN2016077682-appb-000003
i＝0，1，…，23，如图5E所示，无线帧#M中的子帧#2、#3、#7和#8的冗余版本为RV0＝0，无线帧#M+1中的子帧#2、#3、#7和#8的冗余版本为RV1＝2，无线帧#M+2中的子帧#2、#3、#7和#8的冗余版本为RV2＝3，无线帧#M+3中的子帧#2、#3、#7和#8的冗余版本为RV3＝1，无线帧#M+4中的子帧#2、#3、#7和#8的冗余版本为RV0＝0，无线帧#M+5中的子帧#2、#3、#7和#8的冗余版本为RV1＝2。
根据本公开的一些实施例，以下行数据传输为例，冗余版本图样在协议中预先约定，假设协议中定义冗余版本图样为RV0，RV1＝0，2；每一冗余版本连续重复使用次数T以及初始冗余版本RVM均由基站在下行控制信息DCI中通知UE。
具体地，以FDD为例，如图6A所示，假设基站通过DCI为UE的一个下行传输块调度分配了从无线帧#M子帧#0开始的连续24个子帧的资源。同时，DCI中指示每一冗余版本连续重复使用次数T＝6以及初始冗余版本RVM＝RV1＝2。需要说明的是，DCI中可以通过其它的信息域隐式指示每一冗余版本连续重复使用次数。例如：DCI指示跨子帧信道估计的子帧数，每一冗余版本连续重复使用次数通过跨子帧信道估计的子帧数隐式表示，也即每一冗余版本连续重复使用次数等于跨子帧信道估计的子帧数。
基站MAC层确定此次传输的传输块并递交给物理层。物理层对传输块添加CRC以及进行信道编码，之后进行速率匹配。速率匹配模块中的比特收集模块缓存着子块交织后级联的数据。在重复传输期间的每个子帧，比特选择模块根据冗余版本图样、初始冗余版本、每一冗余版本连续重复使用次数以及当前的 传输次数确定每个子帧对应的冗余版本，基于比特收集模块缓存的编码数据，根据确定的冗余版本选择相应的输出数据。
其中，第i次传输的冗余版本为RVn，
Figure PCTCN2016077682-appb-000004
i＝0，1，…，23
如图6B所示，第0至第5个子帧的冗余版本为RV1＝2；第6至第11个子帧的冗余版本为RV0＝0，第12至第17个子帧的冗余版本为RV1＝2，第18至第23个子帧的冗余版本为RV0＝0。
相应地，用户设备侧根据冗余版本图样、初始冗余版本、每一冗余版本连续重复使用次数以及当前的传输次数确定重复传输期间每个子帧对应的冗余版本依次为2，2，2，2，2，2，0，0，……，并按照确定的冗余版本对重复期间各个子帧接收到的数据进行解速率匹配。用户设备侧对于冗余版本相同的连续6个子帧可以进行相干合并，对于冗余版本不同的子帧则进行非相干合并。这样，一方面获得了跨子帧信道估计对信道估计性能的改善，另一方面又可以改变重复传输期间的冗余版本实现增量冗余合并，在高码率传输时获得增量冗余合并的合并增益。
根据本公开的一些实施例，以上行数据传输为例，冗余版本图样在协议中预先约定，假设协议中定义冗余版本图样为RV0，RV1，RV2，RV3＝0，2，3，1；网络侧通过高层信令配置每一冗余版本连续重复使用次数T’，假设T’＝1，进一步通过DCI中的一个比特指示每一冗余版本连续重复使用次数T＝T’或者T等于重复传输期间总的子帧个数。
优选地，网络侧根据本次调度的码率确定每一冗余版本连续重复使用次数T＝T’或者T等于重复传输期间总的子帧个数。当码率较高时，选择T＝T’，即重复传输期间冗余版本是可变的，从而实现增益冗余合并；反之当码率较低时，选择T等于重复传输期间总的子帧个数，即重复传输期间冗余版本是不变的，因为在低码率传输时，增益冗余合并相对相干合并没有明显的增益。
具体地，如图7A所示，以TDD为例，假设UE接收到基站的调度授权，为 UE的一个上行传输块分配了从无线帧#M子帧#0开始的连续24个上行子帧的资源。
此外，假设承载调度授权的DCI中指示T＝T’。UE侧MAC层根据变量CURRENT_IRV确定此次传输的初始冗余版本RVM，假设RVM＝RV2＝3。则第i次传输的冗余版本为RVn，
Figure PCTCN2016077682-appb-000005
i＝0，1，…，23
如图7B所示，自第0个子帧开始，冗余版本依次为RV2＝3，RV3＝1，RV0＝0，RV1＝2，RV2＝3，以此类推。
而若假设承载调度授权的DCI中指示T等于重复传输期间总的子帧个数。则如图7C所示，UE侧MAC层根据变量CURRENT_IRV确定此次传输的初始冗余版本RVM，假设RVM＝RV2＝3。则重复传输期间每个子帧的冗余版本RVn＝RVM＝RV2＝3。
根据本公开的一些实施例，以下行数据传输为例，冗余版本图样由网络侧通过广播消息通知，假设广播的冗余版本图样为RV0，RV1，RV2，RV3＝0，2，3，1；网络侧通过高层信令配置每一冗余版本连续重复使用次数T’，假设T’＝4。此外，协议约定当MCS高于预设阈值MCSthre时，单一冗余版本重复次数T＝T’；否则，T等于重复传输期间总的子帧个数。假设协议约定的MCSthre＝9。
具体地，如图8A所示，以FDD为例，假设基站通过DCI为UE的一个下行传输块调度分配了从无线帧#M子帧#0开始的连续24个子帧的资源。
如图8B所示，假设DCI指示的初始冗余版本RVM＝RV1＝2，DCI指示的MCS＝9，由于MCS小于或等于MCSthre，则重复传输期间每个子帧对应的冗余版本RVn＝RVM＝RV2＝2。
如图8C所示，假设DCI指示的初始冗余版本RVM＝RV1＝2，DCI指示的MCS＝10。由于MCS大于MCSthre，则第i次传输的冗余版本为RVn，
Figure PCTCN2016077682-appb-000006
i＝0，1，…，23，即第0至第3个子帧的冗余版本为RV1＝2；第4至第7个子帧的冗余版本为RV2＝3，第8至第11个子帧的冗余版本为RV3＝1，以此类推。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，该方法还包括：在本端和对端中预先存储每一子帧对应的冗余版本，或者，本端将重复 传输期间内每一子帧对应的冗余版本发送至对端，以指示对端在接收到本端在重复传输期间发送的消息时，采用重复传输期间内每一子帧对应的冗余版本对信息进行解速率匹配。
具体实施时，可以由本端和对端根据至少一种冗余版本以及至少一种冗余版本的使用规则确定重复传输期间每个子帧对应的冗余版本，也可以直接在本端和对端中存储重复传输期间每个子帧对应的冗余版本，当然，也可以由本端将重复传输期间每一子帧对应的冗余版本发送至对端。
在一种可能的实施方式中，本公开的一些实施例提供的方法中，该方法还包括：当本端作为接收端时，本端接收对端在重复传输期间发送的信息，其中，对端根据该重复传输期间内每一子帧对应的冗余版本对信息经编码后的比特流进行速率匹配，存在多个连续子帧对应的冗余版本相同；针对重复传输期间每一子帧发送的信息，本端确定该子帧对应的冗余版本，并根据该子帧对应的冗余版本对该子帧的信息进行解速率匹配。
具体实施时，当本端作为接收端，接收到对端在重复传输期间发送的信息时，确定重复传输期间每一子帧对应的冗余版本，并根据该重复传输期间内每一子帧对应的冗余版本对信息经编码后的比特流进行速率匹配。

在一种可能的实施方式中，本公开的一些实施例提供的装置中，当该装置为网络侧装置时，第二处理单元904通过下行控制信息DCI指示是否采用每一冗余版本连续重复使用次数，具体用于：当通过下行控制信息DCI指示采用每一冗余版本连续重复使用次数时，每一冗余版本连续重复次数确定为本端和对端中预先存储的每一冗余版本连续重复使用次数，或者采用网络侧一端预先配置并通知用户设备的每一冗余版本连续重复使用次数；当通过下行控制信息DCI指示不采用每一冗余版本连续重复使用次数时，每一冗余版本连续重复次数确定为重复传输期间包括的子帧个数。
在一种可能的实施方式中，本公开的一些实施例提供的装置中，第二处理单元904根据预设规则确定每一冗余版本连续重复使用次数，具体包括：第二处理单元904根据信息传输的码率确定每一冗余版本连续重复使用次数。
在一种可能的实施方式中，本公开的一些实施例提供的装置中，第二处理单元904具体用于：当信息传输的码率大于或等于预设阈值时，每一冗余版本连续重复使用次数采用第二处理单元904中预先存储的每一冗余版本连续重复使用次数，或者当该装置为网络侧装置时，采用网络侧装置预先配置并通知用户设备的每一冗余版本连续重复使用次数；当信息传输的码率小于预设阈值时，每一冗余版本连续重复使用次数等于重复传输期间包括的子帧个数。
