本申请主张在2016年8月12日在中国国家知识产权局提交的第201610666591.5号中国专利申请的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，具体涉及一种传输资源的指示方法、装置及存储媒介。
背景技术
相关技术中，SA(控制信息)需要指示Data(数据信息)资源的时频位置，并且为了提高数据的解码成功率，可能需要指示同一个数据包的初重传资源；例如需要指示1次初传加上若干次重传资源。如果SA中能把所有的初重传资源都指示出来，这样接收端对资源占用的情况了解的更为清楚也更为及时，但这在许多情况下是做不到的，原因之一是SA payload(SA载荷)受限，原因之二是数据包的最大传输次数可能是可变的。
为了降低盲检复杂度，SA的载荷是确定的，SA中指示几次传输也是确定的，一般而言，SA中会指示一个数据包的当前传输资源以及之后的总共N次传输，但如果当前传输为最后一次重传，甚至是倒数第N-1次传输，SA中就会出现无效的域，因为从当前传输开始已经没有剩余N次传输给SA指示了，这就造成了浪费。然而，从另一个角度，前面几次传输相比后面的传输得到的指示次数少；例如，初传就只被指示了一次，如果指示初传资源的唯一的SA解码失败，初传资源的位置就无法通过SA解码获得，进而其他终端在选择资源时无法确定性的排除已被占用的初传资源，这显然会降低传输可靠性。
综上，现有的SA指示方式存在域浪费的问题，并且传输可靠性不高。

附图说明
图1表示本公开的实施例提供的传输资源的指示方法的基本步骤流程图；
图2表示本公开的实施例提供的传输资源的指示装置的结构示意图；
图3表示本公开的实施例提供的传输资源的指示装置的结构示意图。
具体实施方式
为使本公开要解决的技术问题、技术方案和优点更加清楚，下面将结合附图及具体实施例进行详细描述。
如图1所示，本公开的实施例提供一种传输资源的指示方法，所述方法包括：
步骤11，根据目标指示规则选择N次传输，并确定选择的N次传输对应的同一数据包的数据信息的N个传输资源；其中，N为用于指示传输资源的控制信息能够指示的最大传输次数，N为大于或者等于2的整数；
步骤12，将确定的N个传输资源在所述控制信息中发送。
需要说明的是，控制信息SA和数据信息data为关联关系，即控制信息SA中指示data的传输资源。SA和data可以在同一子帧上发送，也可以在不同的子帧上发送，但是SA需要不晚于与其关联的data发送。
本公开的实施例中，N为SA能够指示的最大传输次数，即SA的指示域最大可以指示N次传输的数据信息分别对应的传输资源。本公开实施例中，为了避免SA的指示域的浪费，每次发送SA时均在SA中携带N个传输资源。且SA中携带的N个传输资源为同一个数据包的data的传输资源。
例如，当N等于4时，假设数据包总共需要传输6次(1次初传和5次重传)，分别称为第1次传输、第2次传输、第3次传输、第4次传输、第5次传输以及第6次传输。按照目标指示选择4次传输分别为，当前的一次传输(如第5次传输)以及按照某种规则确定的上述6次传输中任意3次传输(如，第6次传输、第1次传输、第2次传输)。
再例如，当N等于4时，假设数据包总共需要传输3次(1次初传和2次重传)，分别称为第1次传输、第2次传输以及第3次传输。按照目标指示选择4次传输分别为，当前的一次传输(如第1次传输)以及按照某种规则确定的上述3次传输中的任意3次传输(如第2次传输、第3次传输以及第1次传输；或者第3次传输、第1次传输、第3次传输)。
综上，本公开的实施例中根据目标指示规则选择的N次传输可以包含不同传输次数的传输，也可以包含相同传输次数的传输，在此不作具体限定。
具体的，本公开的上述实施例中选择的N次传输为：包含当前的一次传输的N次传输。
进一步的，选择的N次传输为：
当前的一次传输，以及从当前的一次传输开始按照顺序连续循环规则或者奇偶循环规则或者预设的循环规则选定的N-1次传输。
其中，顺序连续循环规则具体指：
从当前的一次传输开始根据传输次数的编号依次顺序选择，当选择到最后一次传输时跳转至第一次传输，再从第一次传输开始按照传输次数的编号依次顺序选择，从而实现循环。
奇偶循环规则具体指：从当前的一次传输开始按照奇数传输次数的编号或者偶数传输次数的编号依次顺序选择，当选择到最后一个奇数次数的传输或者最后一个偶数次数的传输时跳转至第一个奇数次数的传输或者第一个偶数次数的传输，再从第一个奇数次数的传输或者第一个偶数次数的传输开始按照奇数传输次数的编号或者偶数传输次数的编号依次顺序选择，从而实现循环。
所述预设的循环规则为：
从当前的一次传输至最后一次传输按照第一规则选择一次或多次传输，当选择到最后一个满足第一规则的传输时跳转至第一个满足第二规则的传输，并从第一个满足第二规则的传输开始按照第二规则选择一次或多次传输；其中，所述第一规则为按照传输次数的编号依次顺序选择，或者按照模N1为M1的传输次数的编号依次顺序选择；所述第二规则为按照传输次数的编号依次顺序选择，或者按照模N2为M2的传输次数的编号依次顺序选择；其中，N1、N2、M1、M2为整数，且N1＞M1，N2＞M2。
具体的，预设的循环规则是指节点或者网络侧自定义的循环规则，其主要包括如下几种方式：
第一规则为按照传输次数的编号依次顺序选择，第二规则为按照传输次数的编号依次顺序选择；此时预设的循环规则与顺序连续循环规则相同；
或者，第一规则为按照传输次数的编号依次顺序选择，第二规则为按照模N2为M2的传输次数的编号依次顺序选择；例如从当前的一次传输开始首先按照传输次数的编号依次顺序选择，当选择到最后一次传输时跳转至第一个模3为0的传输，再按照模3为0的顺序依次选择，实现循环；
或者，第一规则为按照模N1为M1的传输次数的编号依次顺序选择，第二规则为按照传输次数的编号依次顺序选择；例如，从当前的一次传输开始首先按照模3为0的传输次数的编号依次顺序选择，当选择到最后一个模3为0的传输时跳转至第一次传输，再从第一次传输开始按照传输次数的编号依次顺序选择，实现循环。
或者，第一规则为按照模N1为M1的传输次数的编号依次顺序选择，第二规则为按照模N2为M2的传输次数的编号依次顺序选择。这种情况下，当 N为2，M为0时，即按照模2为0的传输次数的编号依次顺序选择，此时与奇偶循环规则中的奇循环规则一致；而当N为2，M为1时，即按照模2为1的传输次数的编号依次顺序选择，此时与奇偶循环规则中的偶循环规则一致。再例如，从当前的一次传输开始直接按照模3为0的顺序依次选择，并且当到达最后一个模3为0的传输时跳转至第一个模3为0的传输，从而实现循环。
需要说明的是，上述预设的循环规则仅为本申请的一个较佳实施例，其他能够实现循环的方式均适用于该申请，在此不作具体限定。
进一步的，本公开的实施例中步骤11之前，所述方法还包括：
步骤110，接收网络侧发送的预先设定的指示规则，其中，所述预先设定的指示规则为一个指示规则或者多个指示规则；
步骤111，从所述预先设定的指示规则中选择一个指示规则作为目标指示规则。
即节点需要预先确定当前采用的目标指示规则；若网络侧发送的预先设定的指示规则为一个指示规则，则接入网络的所有节点均使用这一个指示规则(称为默认规则)，无需每次均通知节点其使用的规则，节点对SA进行解码时则直接参考其默认规则即可。但是为了满足不同的节点和/或不同的数据包的多样性，预先设定的指示规则为多个指示规则时，节点需要选择一个指示规则来作为目标指示规则，从而实现SA对传输资源的指示。
需要说明的是，网络侧发送的预先设定的指示规则可以由网络侧预先设定，也可以由节点预先设定之后再通知网络侧，在此不作具体限定。
具体的，当预先设定的指示规则为多个指示规则时，所述方法还包括：
将用于指示节点当前使用的目标指示规则的指示信息在所述控制信息中发送。即在控制信息SA中增加一个规则指示域，用来指示节点当前使用的是哪一种指示规则。具体的，用于指示节点当前使用的目标指示规则的指示信息可以为目标指示规则的标识。例如用“0”代表第一种指示规则，当SA的规则指示域中为“0”时，通过解析SA即可确定其使用的指示规则为第一种指示规则。
较佳的，本公开的上述实施例中所述数据信息的传输资源包括数据信息 的时域资源以及数据信息的频域资源。
为了更清楚的描述本公开提供的传输资源的指示方法，下面结合一实例对该指示方法进行描述：
假设SA中最大可以指示4次传输，每个数据包总共传输6次。假设在SA中增加一个域来指示节点当前使用的指示规则。
例如预先设定的指示规则包括如下8种，分为0、1、2、3、4、5、6、7来标识相应的指示规则：
0表示指示当前资源，以及按照顺序连续循环指示该数据包对应的其它传输资源。
1表示指示当前资源，以及按奇数连续循环指示该数据包对应的其它传输资源。

若当前传输为第6次传输，则SA中指示第6次传输、第2次传输、第5次传输以及第2次传输分别对应的传输资源。
该例中总共8种规则需要3bit进行指示。如果只有一种预配置的规则，则不需要增加SA的载荷，即不需要增加规则指示域。
本公开的上述实施例中提供有8种不同的指示方式，数据传输过程中可以是发送节点通过自己感知或者第三方反馈发现某次或者某几次传输的解码成功率低，想再次指示那一次或者几次传输，如果接收端缓存了那几次的数据包，就有可能提高解码的成功率，即使接收端没有缓存数据包，至少提高了通过SA解码，发现这几次传输指示的资源位置，自己在进行资源选择的时候可以明确避开这些资源，以降低发生资源冲突的概率。
综上，本公开的实施例提出一种SA循环指示传输资源的方法，可以利用SA中被浪费的指示域，在不增加或者稍微增加SA载荷的情况下，提高数据包解码成功的概率；同时在传输资源周期占用的前提下，接收节点可提高判断资源占用情况的准确度。
