在产生w条序列后，本步骤可以基于各序列生成参考信号，此处不对生成的手段进行限定，如可以为叠加的方式或映射到不同的时频资源的方式。叠加 的方式可以通过序列相加实现。
S130、发送所述参考信号和对应的数据信号。
在生成参考信号后，本步骤可以发送参考信号和对应的数据信号至第二通信节点。
本申请提供了一种参考信号处理方法，应用于第一通信节点，产生w条序列，不同的第一通信节点的所述w的取值不全相同；基于所述w条序列，生成参考信号；发送所述参考信号和对应的数据信号。利用该方法，有效的降低了参考信号的碰撞概率。
以下对本申请进行示例性描述，本申请提供的参考信号生成方法可以认为是可变生成序列数量的参考信号生成方法。在传统通信系统中，(1)所有用户的参考信号碰撞概率一致，对连续干扰消除(Successive Interference Cancellation，SIC)过程来说不是最优的设定。(2)不同用户的参考信号碰撞概率一致，无法为不同用户提供差异化的业务。
本申请针对大规模接入。传统的随机接入方式，每个用户从一个序列池里面选择一条序列作为参考信号，当多个用户选择同一个参考信号时，则发生冲突。这导致了，(1)每个用户发相同数量的序列，则参考信号碰撞概率一致，不是SIC过程的最优的设置。(2)多个用户的优先级一致，紧急业务无法获得更高的优先级。
本申请提出了一种参考信号的生成方式，提高随机接入的成功率，为不同需求的接入提供差异化的业务。本申请中的参考信号可以由一个序列池中的w条序列生成。不同用户的w可以不同，以降低碰撞概率。
图1a为本申请提供的一种传输帧的结构示意图，参见图1a，参考信号可以由w条不重复的序列生成，不同用户的w可以是不同的。
示例1，多个用户(即第一通信节点)生成参考信号的序列数量w可以通过概率分布来生成。
概率分布可以表达成w～f(w),w＝1,2,3…，满足
Figure PCTCN2020138469-appb-000001
对于一个用户来说，每次传输都可以通过f(w)新生成一个w，也可以多次输出使用一次f(w)生成出来的w。
表1为w与f(w)的对应关系表。参见表1，用户设备(User Equipment，UE)基于概率分布确定w，如UE1通过f(w)的值为0.5，确定w 1＝2。其中，p即为f(w)。各UE基于图1b中示出的w与f(w)的对应关系确定各自w的取值。其中，w与f(w)的对应关系可以预存在各UE中。

w 2 3 4 其他
p 0.5 0.28 0.22 0
示例2，多个用户(即第一通信节点)生成参考信号的序列数量w由每个用户当前传输的优先级来确定。对传输的优先级的确定方式不作限定，可以为第一通信节点确定，也可以为第二通信节点指示。
对于一个用户来说，可以每次传输都更新一次优先级，也可以多次传输更新一次优先级，也可以固定使用一个优先级。
表2为w与传输优先级的对应关系表，参见表2，各UE预存有优先级与w的对应关系，各UE基于优先级与w的对应关系和本次传输的优先级，确定各自的w。如UE1本次优先级为1，则UE1的w为4。
表2 w与传输优先级的对应关系表
优先级 1 2 3
w 4 2 1
示例3，多个用户生成参考信号的序列数量w可以由每个用户的数据信息来确定。表3为w与比特符号对应关系表。参见表3，w有3种取值，需要用2比特符号x来指示，这2比特符号x可以是通过对加循环冗余校验(Cyclic Redundancy Check，CRC)前的信息比特；加CRC后且信道编码前的比特；或信道编码后的码字，进行映射得到的。即w可以由加CRC前的信息比特；加CRC后且信道编码前的比特；或信道编码后的码字中取2比特符号(即x)确定。在UE确定w时，可以基于x的取值确定w，如UE从加CRC前的信息比特中取2比特符号作为x，然后基于表3确定对应的w。如UE1中x的取值为01，则UE1中w的取值为3。
表3 w与比特符号对应关系表
x 00/11 01 10
w 2 3 4
示例4，多个用户生成参考信号的序列数量w由第一通信节点的标识信息， 如，UE标识(Identifier，ID)来决定，此时传输信息中要包含UE ID。此实施例可以看作是示例3的一种特殊情况，即用户的数据信息包含UE ID，且用UE ID来确定w。
表4为w与标识信息的对应关系表，参见表4，各UE中可以预存有w与标识信息的对应关系表，各UE基于其标识信息，确定对应的w。
表4 w与标识信息的对应关系表
标识信息 1 2 3 4 ...
w 2 3 4 2 ...
示例5，多个用户生成参考信号的序列数量w由基站分配。这种方式也可以看作是示例4的一种具体的实现方式，即基站侧将UE ID和w进行关联，并通知到UE。当基站解出UE ID时，即可知道对应的w值。图1b为本申请提供的第二通信节点指示第一通信节点w取值的示意图，参见图1b，第二通信节点即基站，向各UE指示对应的w取值，如向UE1指示w＝2。
示例6，当w确定之后，用户，即第一通信节点选择w条序列，并通过此w条序列生成参考信号。其生成参考信号的方式可以是叠加多条序列。
图1c为本申请提供的一种生成参考信号的示意图，参见图1c，序列池中包括8条序列，即z0、z1……z7，各UE从序列池中选取w条序列，通过叠加的方式生成参考信号，如UE1选取序列z2和z6，生成参考信号。
