为详细说明本公开实施例提供的随机接入消息的传输方法，以下将结合几个具体的实施例进行说明。
实施例一
该实施例中，终端设备首先接收多个2-step RACH配置信息。
其中，每个2-step RACH配置信息(简称配置信息)用于指示一个PUSCH资源，同时还用于指示这一个PUSCH资源上，终端设备采用的RV(或RV序列)和/或是否进行重复传输，即重复传输数量K大于或等于1。
上述配置信息是由网络设备广播发送，还可以包括PRACH和PUSCH映射关系信息等。
上述多个配置信息分别指示的多个PUSCH资源中，每个PUSCH资源对应的传输参数可以包括下述至少之一：
在该PUSCH资源上传输的PUSCH的RV或RV序列；
在该PUSCH资源上传输的PUSCH的重复传输数量；以及

可选地，上述多个PUSCH资源中，不同的PUSCH资源可以对应不同的PRACH资源，例如，任意两个PUSCH资源对应的PRACH资源不同。
可选地，上述多个PUSCH资源中，不同的PUSCH资源可以对应相同的PRACH资源，例如，至少两个PUSCH资源对应相同的PRACH资源。
上述PRACH资源包括preamble资源(或preamble资源组)和PRACH机会(或PRACH机会组)中的至少之一。
具体可以参见图2和图3，图2和图3中示意性地显示出3个PUSCH资源，这3个PUSCH资源分别是3个PUSCH资源对应的PUSCH机会，具体见图2和图3中的PUSCH资源1的PUSCH机会、PUSCH资源2的PUSCH机会以及PUSCH资源3的PUSCH机会。
在图2和图3中，PUSCH资源1的PUSCH机会对应的传输参数，也即PUSCH资源1对应的传输参数为RV序列＝{0,2,3,1}，重复传输数量K＝4；PUSCH资源2对应的传输参数为RV序列＝{0,0,0,0}，重复传输数量K＝1；PUSCH资源3对应的传输参数为RV序列＝{0,3,0,3}，重复传输数量K＝2。
在图2中，不同的PUSCH资源可以对应相同的PRACH机会，即图2中的PUSCH资源1、PUSCH资源2和PUSCH资源3可以对应同一个PRACH机会。
在图2中，不同的PUSCH资源可以对应不同的preamble资源，即图2中的PUSCH资源1对应Preamble 0～11；PUSCH资源2对应Preamble 9～23；PUSCH资源3对应Preamble 24～35。
在图3中，不同的PUSCH资源可以对应不同的PRACH机会，即图3中的PUSCH资源1对应PRACH机会1；PUSCH资源2对应PRACH机会2；PUSCH资源3对应PRACH机会3。
通过上述多个配置信息的配置，终端设备在发起随机接入的过程中，即可从多个PUSCH资源中选择一个PUSCH资源，并在该PUSCH资源上，通过该PUSCH资源对应的传输参数发送随机接入消息。

如果配置信息为一个，该配置信息可以用来指示一个PUSCH资源，同时还指示这一个PUSCH资源的多个PUSCH资源单元上，终端设备采用的RV(或RV序列)和/或是否进行重复传输，即重复传输数量K大于或等于1。
如果配置信息为多个，这多个配置信息的作用可以与上述一个配置信息的作用相同，但每个配置信息可以指示的PUSCH资源，以及PUSCH资源的多个PUSCH资源单元对应的传输参数可以不同。
上述配置信息是由网络设备广播发送，可以包括PRACH和PUSCH映射关系信息等。
每个PUSCH资源单元对应的传输参数可以包括下述至少之一：
1)在该PUSCH资源单元上传输的PUSCH的RV或RV序列；
2)在该PUSCH资源单元上传输的PUSCH的重复传输数量；以及

可选地，所述多个PUSCH资源单元中，不同的PUSCH资源单元可以对应相同的传输参数，例如，至少两个PUSCH资源单元对应相同传输参数。
可选地，所述多个PUSCH资源单元中的一个PUSCH资源单元对应至少一个PRACH资源。也即一个PUSCH资源单元可以对应一个PRACH资源，或者，一个PUSCH资源单元可以对应多个PRACH资源。
具体可以参见图4，图4中示意性地显示出PUSCH资源1的PUSCH机会中包含12个PUSCH资源单元，具体见图4中的PUSCH资源单元0～3、PUSCH资源单元4～7以及PUSCH资源单元8～11。
在图4中，PUSCH资源单元0～3对应的传输参数为RV序列＝{0,2,3,1}，重复传输数量K＝4；PUSCH资源单元4～7对应的传输参数为RV序列＝{0,0,0,0}，重复传输数量K＝1；PUSCH资源单元8～11对应的传输参数为RV序列＝{0,3,0,3}，重复传输数量K＝2。
在图4中，不同的PUSCH资源单元可以对应相同的PRACH机会，即图4中的PUSCH资源单元0～3、PUSCH资源单元4～7和PUSCH资源单元8～11可以对应同一个PRACH机会。
在图4中，不同的PUSCH资源单元可以对应不同的preamble资源，即图3中的PUSCH资源单元0～3对应Preamble 0～11；PUSCH资源单元4～7对应Preamble 9～23；PUSCH资源单元8～11对应Preamble 24～35。
通过上述配置信息的配置，终端设备在发起随机接入的过程中，即可从多个PUSCH资源单元中选择一个PUSCH资源单元，并在PUSCH资源单元上通过该PUSCH资源单元对应的传输参数发送随机接入消息。
具体地，终端设备可以根据下述至少之一从多个PUSCH资源单元中选择一个PUSCH资源单元：
