具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述。

需要说明的是，将基带预编码矩阵配置在待发送的基带型接入信号上；将射频预编码矩阵配置在待发送的射频型接入信号上；为待发送的接入信号配置发送天线端，这几个处理也可以产生发送波束。
在一实施例中，所述根据所述指示信令确定接入信号的发送方式，包括：
根据所述接入方式通知信令确定所述发送方式，或者根据检测所述参考信号确定所述发送方式。
在一种可选地具体的实现过程中，对于根据检测所述参考信号确定所述发送方式，需要说明的是，终端可以根据接收到的参考信号，选择一个由基站到终端的最优下行波束方向；然后考虑到TDD系统中上行信道和下行信道的互易性，选择得到最优下行波束方向，即为终端选择的发送接入信号的波束方向。
具体地，所述根据检测所述参考信号确定所述发送方式，包括：

从所述参考信号的M种发送方式中选择N种发送方式；其中，N小于等于M；
至少根据选择的所述参考信号的N种发送方式确定所述接入信号的N种发送方式。
详细来说，选择的所述参考信号的N种发送方式与所述接入信号的N种发送方式存在映射关系，从而可以根据选择的所述参考信号的N种发送方式确定所述接入信号的N种发送方式；

进一步地，所述接入信号发送失败，包括：没有接收到接入响应信号；或者接收到的接入响应信号中没有发送与所述接入信号对应的应答信息。
需要说明的是，接入响应消息是基站发送的用来应答所述接入信号的消息；可以包括针对一个或多个接入信号的应答信息。
具体地，按照重新确定的发送方式发送所述接入信号，具体包括：
按照前次发送所述接入信号相同的发射功率重新发送所述接入信号；或者，

需要说明的是，预设的功率计算公式可以由目前已有的标准制定，本实施例不再赘述。
在上述方案中，所述接入信号占用的接入信道资源与所述接入信号的发送方式存在第一映射关系；也就是说，不同发送方式的接入信号在发送时占用的接入信道资源是不同的，通过检测到接入信号所在的接入信道资源，基站就能够获知终端选择的发送方式；
或者，所述接入信号占用的接入信道资源与所述参考信号的发送方式存在第二映射关系；也就是说，不同的接入信道资源可以隐含指示所述参考信号的不同发送方式，通过检测到接入信号所在的接入信道资源，基站就能够获知终端选择的发送方式；
或者，所述接入信号与所述接入信号的发送方式存在第三映射关系；也就是说，通过识别接入信号，基站就能够获知终端选择的发送方式；即将所述接入信号划分为一个或多个集合，不同的接入信号集合对应接入信号的发送方式不同；
或者，所述接入信号与所述参考信号的发送方式存在第四映射关系；也就是说，通过识别接入信号，基站就能够知道终端选择的发送方式。即将所述接入信号划分为一个或多个集合，不同的接入信号集合对应的发送方式不同。

在上述方案中，所述基站向所述终端发送与所述接入信号对应的接入响应信号，具体包括：
所述基站根据所述终端发送所述接入信号占用的接入信道资源位置；或者根据所述接入信号，确定发送所述接入响应信号的发送参数；其中，所述发送参数可以包括以下至少一项：基带预编码矩阵、射频预编码矩阵、天线端口、发送波束、发送波束方向和发射功率。
具体地，基站可以根据基带预编码矩阵确定所述参考信号的基带信号；或者，

具体地，基站反馈的接入响应消息用于应答终端发送的接入信号，基站根据检测到的终端发送的接入信号所在的集合确定所述接入响应消息的发送方式所述接入响应消息包括以下至少之一：
针对向所述基站发送上行数据消息的发送方式的指示信息；其中，上行数据消息可以是Msg3消息，用来应答基站发送的接入响应消息的；

实施例三
参见图3，其示出了本发明实施例提供的一种无线接入的方法，所述方法包括：
S301：终端采用第一方法发送接入信号；
S302：在发送失败K次后，终端采用第二方法发送所述接入信号。
需要说明的是，所述接入信号发送失败，包括：没有接收到接入响应 信号；或者接收到的接入响应信号中没有发送与所述接入信号对应的应答信息。
并且，图3所示的技术方案中所述的第一方法为实施例一中所述的任一接入方法，所述第二方法为基站配置或终端自行确定的发送方法，并且所述第一方法与所述第二方法不同；所述K大于等于1。
示例性地，当所述终端采用所述第一方法发送所述接入信号时，所述接入信号占用第一接入信道资源；
当所述终端采用所述第二方法发送所述接入信号时，所述接入信号占用第二接入信道资源；其中，所述第一接入信道资源与所述第二接入信道资源由基站进行配置。
示例性地，当所述终端采用所述第二方法发送所述接入信号时，所述终端的发送天线的模式为全向天线模式，即发送的接入信号不存在定向波束方向。
例如，所述终端第K次发送接入信号，如果所述终端没有接收到所述接入响应信号，或者所述终端接收到所述接入响应信号但在所述接入响应信号中没有发送与所述终端发送的接入信号对应的应答信息时，所述终端第K+1次重新发送所述接入信号，所采用的发送方式与第K次发送所述接入信号所采用的发送方式不同。
在一个具体示例中，以K＝5为例，终端第5次重新发送接入信号，如果终端没有接收到所述接入响应信号，或者所述终端接收到所述接入响应信号但在所述接入响应信号中没有发送与所述终端发送的接入信号对应的应答信息时，所述终端第6次重新发送所述接入信号，所采用的发送方式与第5次重新发送所述接入信号所采用的发送方式均不相同。
可以理解地，图3所示的技术方案可以单独实施，也可以作为图1所示技术方案的优选实施方式。
实施例四

需要说明的是，N1为正整数，N1的取值可以通过基站向终端发送的配置消息进行指示，但也不限于此种方式。N2也为正整数且N2小于或等于N1。
这里提到的N1个接入信道资源是终端一次发送接入信号同时占用的信道资源。N1个接入信道在时域上占用的资源不同，或，所述N1个接入信道在时域上占用的资源不重叠，以避免产生信号干扰。而对于N1个接入信道中每个接入信道上采用一种发送方式来发送接入信号，且采用的每一种发送方式都来自于上述N2种发送方式。最优选的方案中，N1＝N2，即，每一个接入信道上均采用不同的发送方式来发送接入信号，通过这种随机信号的方式，提高信号接入的概率。
可选地，在预设的发送次数内，每一次均选择相同的N2种发送方式，以及超过预设的发送次数后，选择N3种发送方式，其中，N3为正整数，所述N2种发送方式采用的发送方式两两不同，所述N3种发送方式与所述N2种发送方式采用的发送方式不相同。
具体地，所述N3种发送方式与所述N2种发送方式中部分的发送方式不同；或者，所述N3种发送方式与所述N2种发送方式全部的发送方式都不同。
其中，所述预设的发送次数由基站配置或由标准默认配置或由所述终端配置。
在一实施例中，所述N2种发送方式和所述N3种发送方式均取自于一个发送方式集合Q。
这里，所述发送方式集合Q中的发送方式由所述基站配置或由标准默认配置或由终端根据检测参考信号确定。
其中，所述参考信号包括以下至少一项：

在一个实施例中，超过预设的发送次数后，选择N3种发送方式，N3＝1，此时终端采用全向天线的方式发送接入信号，即发送的接入信号不存在定向波束方向。
另一个实施例中，超过预设的发送次数后，选择N3种发送方式，其中N2＝1，即，只选择一个接入信道进行信号的发送。
可选地，所述终端在接入信道资源中选择N1个接入信道资源，并且采用N2种发送方式发送接入信号，具体包括：
所述终端从P个接入信号集合中选择一个接入信号集合，并且从选择的接入信号集合中选择一条接入信号，将选择的接入信号在选择N1个接入信道资源上发送；
其中，所述P个接入信号集合与基站向终端发送参考信号的发送方式存在一一映射关系。
需要说明的是，每个接入信号集合中包括至少一个接入信号，或至少一个接入信号的索引，或至少一个生成接入信号使用的接入序列，或至少一个生成接入信号使用的接入序列索引；而所述P个接入信号集合可以由所述基站配置，并且所述P个接入信号集合与基站向终端发送参考信号的发送方式存在一一映射关系可以理解为：终端通过检测基站发送的参考信号，选择一种最优的参考信号的发送方式；并且在所述参考信号的发送方式对应的进入信号集合中选择一个接入信号在接入信道资源上发送；或者，基站通过检测到终端选择的接入信号，获知所述接入信号对应的所述的接入信号集合，并且通过所述接入信号集合获知终端最优的参考信号的发送方式。
可选地，本实施例还可以包括：终端接收基站发送的接入响应消息。需要说明的是，基站反馈的接入响应消息用于应答终端发送的接入信号，基站根据检测到的终端发送的接入信号所在的集合确定所述接入响应消息 的发送方式。
