用户设备UE发起基于竞争的随机接入contention-based random access通常包括如图1所示的4个步骤，消息1(Msg1):通过PRACH发送，承载一个随机接入前导(preamble)。消息2(Msg2)：通过PDCCH调度、在PDSCH上发送，消息2指示UE用来发送消息3(Msg3)的时频资源等调度信息。Msg3：初始传输通过PUSCH发送，重传通过PDCCH调度的PUSCH发送。消息4(Msg4)：通过PDSCH发送，一般包含contention resolution identity竞争解决消息,使UE与BS建立RRC连接,UE进入RRC_connected state。上述4个步骤通常耗时较长，因此需要新的随机接入来提高随机接入的效率，同时保证随机接入的成功率。

具体实施方式
下面结合本申请中的附图对本申请进行描述。
图2给出了本申请提供的一种通信系统示意图。该通信系统可以包括至少一个网络设备100(仅示出1个)以及与网络设备100连接的一个或多个终端设备200。
网络设备100可以是能和终端设备200通信的设备。网络设备100可以是可以是任意一种具有无线收发功能的设备。包括但不限于：基站(例如，基站NodeB、演进型基站eNodeB、第五代(the fifth generation，5G)通信系统中的基站、未来通信系统中的基站或网络设备、WiFi系统中的接入节点、无线中继节点、无线回传节点)等。网络设备100还可以是云无线接入网络(cloud radio access network，CRAN)场景下的无线控制器。网络设备100还可以是5G网络中的网络设备或未来演进网络中的网络设备；还可以是可穿戴设备或车载设备等。网络设备100还可以是小站，传输节点(transmission reference point，TRP)等。当然本申请不限于此。

图3为本申请提供的一种通信方法的交互流程示意图，该方法可包括以下步骤：
可选的，S300、网络设备向UE发送配置信息。
网络设备可能通过一个或者多个下行指示信息或者信道发送该配置信息给UE，所述下行指示信息可以是系统消息，PRACH配置，小区切换handover命令，或者RRC高层信令。
可选的，在S300之前，所述方法还可以包括，S299，网络设备生成配置信息。网络设备可以综合当前网络情况，自身能力等一个或者多个情况生成配置信息。例如可以根据测量间隔位置调整下行信号与传输机会的关联参数，或者可以根据上下行配比调整调整下行信号与传输机会的关联参数以减小冲突。还可以在配置信息中增加更多的信息，以帮助UE完成随机接入，提高随机接入效率和成功率。
S301、UE接收网络设备发送的配置信息。
该配置信息包括指示信息indicator，下行信号测量阈值，配置的PUSCH阈值payload，时间差阈值，测量间隔位置，下行信号与传输机会的关联参数等一个或者多个。应该理解的是，该配置信息还可以包括其他任何对UE随机接入有用的信息，本申请对此不做限制。还应该理解，上述一个或者多个信息可以是预先配置的，例如预先存储在UE和网络设备中，此种情况网络设备不需要发送。
其中，指示信息Indicator(或者称为控制指示信息)：用来调整预设关系，例如该指示信息可以是一个开关控制功能，用来指示在当前配置信息下是否支持第一种随机接入；也可以用来指示“预设关系”是否生效，不同的指示值对应的不同的预设关系，因此对应不同的UE处理行为；还可以是用来指示是否有不同的传输机会与下行信号的映射关系；还可以用来指示是否支持同一个UE同时发起多种随机接入过程，例如UE根据指示Indicator，可以在选择第一随机接入消息，发送给网络设备，并在收到对应的随机接入响应之前，或者在没有完成第一种随机接入，也没有切换到第二种随机接入之前，UE还选择第二随机接入消息，发送给网络设备。其中，该关联参数包括该下行信号与第一种随机接入传输机会的关联参数，和，该下行信号与第二种随机接入传输机会的关联参数。此时，第一种随机接入和第二种随机接入使用不同的关联参数可以获得传输机会，网络设备可以通过随机接入消息在何种传输机会上发送确定UE发送的是哪种随机接入消息。该关联参数也可以包括一种PRACH传输机会的关联参数，此时第一种随机接入和第二种随机接入公用该关联参数对应的传输机会。其中，在所述第一种随机接入中，所述UE选择所述第一随机接入消息，在所述第二种随机接入中，所述UE选择所述第二随机接入消息。
在一种关联参数中，可以包括PRACH的关联参数，也还可以包括PUSCH的关联参数；也可以只包括PRACH的关联参数，PUSCH的可以根据PRACH来确定。
S302、所述UE根据所述配置信息和第一预设规则选择第一随机接入消息，或者第二随机接入消息；其中，所述第一随机接入消息包括前导序列preamble和物理上行共享信道PUSCH；所述第二随机接入消息包括preamble，且不包括PUSCH。应该理解的是，所述随机消息还可以包括除preamble和PUSCH以外的其他信息，本申请对此不做限制。
该预设规则也可称为预设关系，该预设规则可以存储在UE和/或网络设备中，也可以 由未存储的一方发送给另一方。其中，所述预设规则包括下述中的一种或者多种，下行信号的测量结果与下行信号测量阈值的关系，待发送的PUSCH payload与配置的PUSCH payload的关系，传输机会的时间先后关系，传输机会与测量间隔位置的关系，传输机会与其他上行信号的优先级关系。在步骤S302中，还需要考虑UE自身的能力，例如UE是否支持发送第一随机接入消息(是否支持第一种随机接入)。
通过上述方法，可以让UE在自身支持的状况下，根据当前网络状态选择发送第一随机接入消息，或者第二随机接入消息，从而提高随机接入的效率。因为通过发送第一随机接入消息可以减少随机接入的步骤，从而提高随机接入的效率。
可选的，在S301之后，所述方法还包括，S303、所述UE(例如根据所述配置信息中的下行信号与传输机会的关联参数)选择一个或者多个第一传输机会。其中，第一传输机会是可能发送随机接入消息的传输机会。其中，第一传输机会包括第一PRACH的传输机会和/或第一PUSCH的传输机会。第一PRACH传输机会用于传输preamble和/或其他信息，第一PUSCH传输机会用于传输PUSCH和/或其他信息。UE通常是根据PRACH传输机会找到相应的PUSCH传输机会。传输机会是一种传输资源，或者称为时频资源，或者还可以称为传输位置。该时频资源包括时域位置(例如slot(s))和频域位置(例如RB(s))。该一个或者多个第一传输机会可以组成一个集合，UE可以在其中选择实际发送随机接入消息的传输机会。因此，可选的，所述方法还可以包括，S3051，UE在一个或者多个第一传输机会上发送随机接入消息。当然，也可以不在第一传输机会上发送随机接入消息，而是根据其他条件进一步选择实际发送随机接入消息的传输机会。可选的，在选择第一传输机会时也可以考虑UE的能力和第一预设关系。应该理解本申请不限定S302和S303的时间先后顺序，可以S302在S303之前，也可以之后，还可以同时，当然还可以没有S303.
可选的，在S301之后，所述方法还包括，S304，所述UE根据所述配置信息和第二预设规则，选择，一个或者多个第二传输机会；其中，所述一个或者多个第二传输机会用于发送所述第一随机接入消息，或者所述第二随机接入消息。其中，第二传输机会包括第二PRACH的传输机会和/或第二PUSCH的传输机会。第二PRACH传输机会用于传输preamble和/或其他信息，第二PUSCH传输机会用于传输PUSCH和/或其他信息。在UE选择第一传输机会后(或者可以没有UE选择第一传输机会这个步骤)，UE可以根据目前冲突的情况以及其他条件，例如是否与其他上行传输信号和/或测量间隔位置冲突，决定该第一传输机会是否可以实际用于发送随机接入消息(或者直接决定某一传输机会是否可以用于发送随机接入消息)，或者对所述第一传输机会或者其他上行传输信号做相应的处理以用来实际发送随机接入消息。因此，可选的，所述方法还可以包括，S3052，UE在一个或者多个第二传输机会上发送随机接入消息。应该理解，本申请不限制S304和S303之间的时间先后顺序，本申请可能没有S303和/或S304。
可选的，所述方法还包括S306，网络设备检测所述UE发送的随机接入消息。S306具体包括，网络设备在一个或者多个传输机会关联的下行信号的beam方向和PRACH传输机会上检测随机接入消息的PRACH；网络设备根据检测到PRACH传输机会，以及PRACH传输机会与PUSCH传输机会的映射关系，在对应的一个或者多个PUSCH传输机会上检测或者尝试检测PUSCH。
一般的检测和尝试检测的区别在于网络设备是否能够判断UE进行的是第一种随机接 入还是第二种随机接入。在网络设备可以判断UE进行的是第一种随机接入中，网络设备是检测；在网络设备可以判断UE进行的是第二种随机接入中，网络设备不检测PUSCH；在网络设备不能判断UE进行的是哪一种PRACH过程时，网络设备尝试检测PUSCH。
网络设备判断UE进行的是哪一种PRACH，可以根据指示信息，检测到PRACH的传输机会，或者preamble的格式中的一种或者多种，判断UE进行的是哪一种PRACH。
可选的，所述方法还包括S307，网络设备将检测到的多个PUSCH做HARQ合并。
可选的，在S302之前，所述方法还包括UE获取一个或者多个下行信号的测量结果Mrsrp。
其中，下行信号可以是任何下行信号，例如SSB或者CSI-RS。UE可以对网络设备多个beam上发送的下行信号进行测量，得到下行信号的测量结果，例如包括测量SSB的SS-RSRP，或者CSI-RS的RS-RSRP，以找到适合发送随机接入消息的beam。还可以将下行信号测量阈值与下行信号的测量结果进行比较，以确定所述下行信号对应的传输机会可以用来发送第一随机接入消息，还是发送第二随机接入消息。
参考图4，当所述配置信息包括，第一下行信号测量阈值T1，第二下行信号测量阈值T2，和下行信号与传输机会的关联参数，其中，第一下行信号测量阈值小于第二下行信号测量阈值，其UE支持第一种随机接入时，所述第一预设规则具体包括，至少一个下行信号的测量结果大于所述第二下行信号测量阈值，所述UE可能选择所述第一随机接入消息；或者，任意一个下行信号的测量结果均小于所述第一下行信号测量阈值，所述UE可能选择所述第二随机接入消息。应该理解，所述第一预设规则还可以表述为：如果任何一个下行信号的测量结果满足T1<＝Mrsrp<T2，所述下行信号关联的传输机会可能用于第二种随机接入；如果任何一个下行信号的测量结果满足T2<＝Mrsrp，该下行信号关联的传输机会可能用于第一种随机接入；如果没有满足上述条件的测量结果，UE可选择任何一个下行信号关联的传输机会，只能进行第二种随机接入。
可选的，如果配置信息包括指示信息，则预设关系可以为：如果指示信息为第一值(例如Indicator＝1)，则可以表示当前的活跃用户数不多，网络可能分配不同的PRACH资源(传输机会)分别给第一种随机接入和第二种随机接入，来帮助减少随机接入资源共享，降低碰撞概率和网络设备盲检测的概率。此时，第一预设规则可以与之前保持不变。如果指示信息为第二值(例如Indicator＝0)，则可能表明当前可能的随机接入用户数较多，随机接入容量受限，第一种随机接入和第二种随机接入需要共享传输机会，网络设备会进一步通过其他方式识别UE发起的是哪一个随机结果过程。此时，第一预设规则可以表述为:如果任何一个下行信号的测量结果满足T1<＝Mrsrp<T2，该下行信号关联的RACH资源可能用于第二种随机接入；如果任何一个下行信号的测量结果满足T2<＝Mrsrp，UE还需通过其他方法进一步确定是否发起第一种随机接入。如果没有满足上述条件的测量结果，UE可选择任何一个下行信号，且只能进行第二种随机接入。
上述方法可以在下行信号测量质量较好的情况下，尽量选择发送第一随机接入消息，以提高随机接入的效率，在下行信号测量质量不好时，可以选择发送第二随机接入消息，以提高接入的成功率。
参考图5，当所述配置消息包括，下行信号测量阈值T1，配置的PUSCH payload阈值，和下行信号与传输机会的关联参数，UE支持第一种随机接入时，所述第一预设规则 具体包括，如果任何一个下行信号的测量结果满足T1<＝Mrsrp，该下行信号关联的传输机会可能用于第一种随机接入或者第二种随机接入(也就是说UE可以选择第一种随机接入消息或者第二种随机接入消息)。此时，如果UE待传输的PUSCH payload小于等于该配置的PUSCH payload，则UE选择一个同时满足下行测量阈值和PUSCH payload阈值条件的下行信号关联的传输机会用于第一种随机接入(或者说，UE选择第一种随机接入消息)；如果UE待传输的PUSCH payload大于该配置的PUSCH payload，则UE选择一个满足下行测量阈值条件的下行信号关联的传输机会用于第二种随机接入(或者说，UE选择第二种随机接入消息)。如果任何一个下行信号的测量结果满足T1>Mrsrp，UE可选择任何一个下行信号关联传输机会，且只能进行第二种随机接入(或者说，UE选择第二种随机接入消息)。
可选的配置消息还可以包括指示信息，如果指示信息为第一值(例如Indicator＝1)，则可以表示网络设备支持第一种随机接入，此时该第一预设规则与上述保持一致。如果指示信息为第二值(例如Indicator＝0)，则可以表示网络设备不支持第一种随机接入，此时UE只能使用第二种随机接入，即只能选择第二随机接入消息。
应该理解，配置的PUSCH payload用来描述PUSCH承载的数据信息(例如传输块transportblock)的大小。由于传输的数据信息与PUSCH的资源大小和码率(例如MCS)相关，等效的，在实际网络配置中，还可以用PUSCH的资源块大小，或者MCS的大小来描述配置的PUSCH payload。同时，为了降低网络配置信息的开销，PUSCH payload的描述还可以按照等级来配置。例如level 0对应PUSCH payload不大于56 bits，level 1对应PUSCH payload不大于72 bits。
上述方法中，网络设备可以根据自身是否支持第一种随机接入或者当前的活跃用户数等，提前预留PUSCH资源(传输机会)，并，提前做好盲检测的准备。不同的PRACH过程的传输机会可以重叠，以提高随机接入的容量。上述方法一般适用于小区信号普遍较好，活跃用户较多的情况。
参考图6，当所述配置信息包括，时间差阈值和下行信号与传输机会的关联参数，其中，所述关联参数包括所述下行信号与第一种随机接入传输机会的关联参数，和所述下行信号与第二种随机接入传输机会的关联参数，其UE支持第一种随机接入时，所述第一预设规则具体包括，下行信号关联的第一种随机接入传输机会对应的参考时刻与下行信号关联的第二种随机接入传输机会对应的参考时刻的差值，小于等于所述时间差阈值，所述UE选择所述第一随机接入消息(或者可以理解为第一种随机接入传输机会对应的参考时刻早于第二种随机接入传输机会对应的参考时刻的时间差大于或者等于该时间差阈值选择所述第一随机接入消息)；或者，下行信号关联的第一种RACH传输机会对应的参考时刻与所述下行信号关联的第二种随机接入传输机会对应的参考时刻的差值，大于所述时间差阈值，所述UE选择所述第二随机接入消息(或者可以理解为第一种随机接入传输机会对应的参考时刻早于第二种随机接入传输机会对应的参考时刻的时间差小于该时间差阈值选择所述第二随机接入消息)；
具体的，第一预设规则还可以表述为，如果第一种随机接入传输机会所对应的参考时间点X1，第二种随机接入传输机会所对应的参考时间点X2，在时间先后上的关系满足(X1-X2)大于时间差阈值,则UE确定只能使用第二种随机接入(即UE选择第二种随机接 入消息)；如果(X1-X2)小于等于时间差阈值，则UE可以选择第一种随机接入。参考时间点是指为了比较而选择的一个参考位置，例如可以是传输机会的起始符号，终止符号,随机接入消息中preamble起始或者终止符号，随机接入消息中payload部分的起始或者终止符号，第二随机接入消息对应的随机接入响应的起始或者终止符号，第一随机接入消息对应的基站发送的响应消息(例如竞争解决消息)的起始或者终止符号，或者其他某个特定位置等。
可选的，配置信息包括指示信息，则UE可以根据指示信息确定是否需要调整第一预设规则。
通过上述方法UE能够根据可能的完成随机接入的时间，选择一个时延更低的随机接入。由于下行信号对应的第二种随机接入传输机会和第一种随机接入传输机会可能在时间上有先后关系；当某个第二种随机接入传输机会大大早于第一种随机接入传输机会，使得即使UE进行第一种随机接入，仍然不会达到减低接入时延，提高接入效率时，UE可以选择第二种随机接入，从而提高接入效率，同时节省不必要的PUSCH资源浪费，降低UE功耗和网络设备盲检测复杂度。
参考图7，可选的，在S304中，如果UE选择所述第一随机接入消息,配置信息包括测量间隔位置时，所述第二预设规则包括，所述UE选择所述第二传输机会时，不基于所述测量间隔位置。在发送第一随机接入消息时不考虑测量间隔位置，能够及时的发起第一种随机接入，最大化的降低时延。
可选的，在S304中，如果UE选择所述第一随机接入消息,配置信息包括测量间隔位置时，所述第二预设规则包括，所述第一传输机会与所述测量间隔位置冲突，所述UE不选择所述第一传输机会为所述第二传输机会，或者，以所述第一传输机会的某个参考时刻(例如第一PRACH传输机会的起始符号或终止符号，或者，第一PUSCH传输机会的起始符号或终止符号)为起点，在时间上向后调整N个时间单元，选择为第二传输机会；其中，所述冲突包括，所述第一传输机会与所属出测量间隔位置在时间上至少部分重叠，或者间隔小于M个时间单元，M和N是大于等于0的正整数。
所述UE不选择所述第一传输机会为所述第二传输机会还可以称为，UE主动丢掉所述第一传输机会，或者UE不期待在该第一传输机会上被同时调度了其他上行传输。在发送第一随机接入消息时考虑测量间隔位置，能够及时的获得目标小区的信号质量，最大化潜在小区切换等行为的成功率。其中，时间单元可以是符号，时隙(slot)，小时隙(mini slot)，帧，子帧，半帧等等，本申请对此不做限制。
可选的，通过测量间隔位置扔掉冲突的传输机会或者后移情况也可以是网络设备主动完成的。网络设备可以通过调整下行信号与传输机会的关联参数解决与测量间隔位置冲突的情况。
通过上述方法，网络设备根据自身网络环境的状态，如活跃用户数，资源，容量等，灵活控制UE在发送随机接入消息时是否考虑测量间隔位置。同时，UE也可以根据自身能力，以及当前网络状态选择是否考虑测量间隔位置。此外，上述方法还可以增加指示信息用来指示是否考虑测量间隔位置。应该理解的是，在本申请中，上述考虑因素还可以是测量间隔位置以外的其他网络状况。
参考图7，可选的，在S304中，所述第二预设规则还可以包括，所述第一传输机会与 其他上行传输冲突，以所述第一传输机会为起点，在时间上向后调整N个时间单元，选择为第二传输机会；所述第一传输机会与其他上行传输冲突，选择所述第一传输机会为所述第二传输机会，且不在所述第二传输机会上发送所述其他上行传输；所述第一PRACH传输机会与其他上行传输冲突，不选择所述第一PRACH传输机会为所述第二PRACH传输机会；所述第一PUSCH传输机会与其他上行传输冲突，不选择所述第一PUSCH传输机会为所述第二PUSCH传输机会；所述第一PUSCH传输机会与其他上行传输冲突，选择第一个所述第一PUSCH传输机会为所述第二PUSCH传输机会，且不在所述第二PUSCH传输机会上发送所述其他上行传输，同时，不选择除所述第一个所述第一PUSCH传输机会之外的第一PUSCH传输机会为所述第二PUSCH传输机会；或者，所述第一PUSCH传输机会的至少一部分与其他上行传输冲突，同时第一PUSCH传输机会的第一部分不与其他上行传输冲突，选择所述第一PUSCH传输机会中与其他上行传输不冲突的部分为所述第二PUSCH传输机会，且在所述第一PUSCH传输机会中与其他上行传输冲突的部分只发送所述其他上行传输，所述第一PUSCH传输机会的第一部分可以是第一个时间或频率单元，或者第一个时频资源块，或者是多次重复传输的PUSCH的第一次传输；其中，所述冲突包括，所述第一传输机会与所属出测量间隔位置在时间上至少部分重叠，或者间隔小于M个时间单元，M和N大于0。其中，第一传输机会包括，第一PRACH传输机会和第一PUSCH传输机会，第二传输机会包括，第二PRACH传输机会，第二PUSCH传输机会。在上述过程中UE可以选择第一随机接入消息。
应该理解该第二预设规则还可以表述为，1)第一随机接入消息中的任何一部分(例如preamble或者PUSCH)，与该UE的其他上行传输(例如PUSCH/PUCCH/SRS)在时间上至少部分重叠，或者间隔少于N个时间单元(符号)时，UE不发送第一随机接入消息；或者，2)第一随机接入消息中的PRACH部分，与其他上行传输在时间上至少部分重叠、或间隔少于N个时间单元(如，符号)时，UE在当前机会不发送第一随机接入消息，直到确定下一个满足第二预设规则的传输机会；或者，3)第一随机接入消息中的PUSCH部分，与其他上行传输在时间上至少部分重叠、或间隔少于N个时间单元(如，符号)时，UE不发送随机接入消息的PUSCH部分，或者将PUSCH的传输位置在时间上向后调整Y个时间单元(如，符号、子帧等)；或者，4)随机接入消息中的PUSCH部分，与其他上行传输在时间上至少部分重叠、或间隔少于N个时间单元(符号)时，UE跳过当前的随机接入消息传输机会，选择下一个随机接入消息传输机会，且重复检查该第二预设条件，直到确定满足第二预设规则的传输机会。
可选的，一般的随机接入消息与其他上行传输的优先级如下所示：随机接入消息vs.PUSCH/PUCCH,UE不发送随机接入消息；随机接入消息vs.SRS,UE不发送SRS。
可选的，无论是第一传输机会，还是其他上行信道、信号的传输，在某种程度上，都是网络设备已知的。因此，另一种实现方式为，当确定第二传输机会时，UE并不做额外的判断，可以由网络设备调度实现来避免类似情况的发生，例如通过调整下行信号与传输机会的关联参数，或者通过调度其他上行传输不与任意一个随机接入传输机会冲突。然而，这必然会带来一定的调度限制，这种调度限制也应该由规范以预设规则的形式明确体现出来，成为确定第二传输机会的步骤之一。例如，UE不期待随机接入消息与其他PUSCH/PUCCH/SRS在时间上满足某种关系，意味着此种情形，应由网络设备调度避免出 现。
上述方法提供了与上行传输冲突的情况如何进行随机接入的方法，提高了随机接入的成功率。
可选的，在S299中，在生成下行信号与传输机会的关联参数时，具体的可以是生成下行信号与PRACH传输机会的关联参数时，网络设备和/或UE根据所述关联参数和第一预设规则中的下行信号与PRACH传输机会的第一映射规则，确定映射到任意一个下行信号的PRACH传输机会为第二随机接入消息的传输机会；网络设备和/或UE将未映射到任意一个下行信号的PRACH传输机会，根据第二预设规则中的下行信号与PRACH传输机会的第二映射规则，确定为发送第一随机接入消息的传输机会。。
可选的，在S306中，网络设备确定PRACH传输机会对应的beam方向，在PRACH传输机会和beam方向检测PRACH，并根据检测到的PRACH的preamble格式和/或传输机会，以及PRACH传输机会与PUSCH传输机会的对应关系，在一个或者多个第一PUSCH传输机会上检测PUSCH。
可选的，配置信息包括第一下行信号与传输机会的关联参数和第二下行信号与传输机会的关联参数(具体为第一下行信号与PRACH传输机会的关联参数和第二下行信号与PRACH传输机会的关联参数)，其中UE支持第一种随机接入。则S302可以包括，UE根据第一下行信号与PRACH传输机会的关联参数和第二下行信号与PRACH传输机会的关联参数，选择第一随机接入消息或者第二随机接入消息。如果第一下行信号与PRACH传输机会的关联参数关联第一种随机接入，第二下行信号与PRACH传输机会的关联参数关联第二种随机接入，则第一预设规则可以包括，根据第一下行信号与PRACH传输机会的关联参数选择的传输机会只能进行第一种随机接入；根据第二下行信号与PRACH传输机会的关联参数选择的传输机会只能进行第二种随机接入。进一步的，配置信息还可以包括第一下行信号测量阈值，第二下行信号测量阈值。如果第一下行信号与PRACH传输机会的关联参数对应的任何一个下行信号的测量结果大于或者等于第一下行信号测量阈值，则UE可以选择所述满足下行信号的测量结果大于或者等于第一下行信号测量阈值的所述下行信号对应的传输机会，进行第一种随机接入；或者，如果第一下行信号与PRACH传输机会的关联参数对应的任意一个下行信号的测量结果小于第一下行信号测量阈值，则UE可以选择所述任意一个下行信号对应的PRACH传输机会，进行第一种随机接入。
上述方法将第一种随机接入与第二种随机接入分开使用不同的PRACH传输机会，最小化对现有随机接入和容量的影响。
可选的，在S3051和S3052中，UE向所述网络设备发送随机接入消息具体可以包括：所述UE，在一个所述第一传输机会上，向所述网络设备发送所述第二随机接入消息；所述UE，在多个所述第一传输机会上，向所述网络设备发送所述第一随机接入消息；其中，所述多个第一传输机会包括，P个第一PRACH传输机会和Q个第一PUSCH传输机会，P和Q是大于等于1的正整数。其中，P和Q可以是预先配置的，可以为任何值。P个第一PRACH传输机会是在频率或时间上连续的P个，关联同一个下行信号的PRACH传输机会。Q个第一PUSCH传输机会是根据配置的PUSCH payload或下行信号的测量结果或与第一PRACH传输机会的关联关系中的一下项或者多项确定的。如果下行信号的测量结果低于下行信号测量阈值或者配置的PUSCH阈值大于待发送的PUSCH payload或者相对于 第一PRACH传输机会的某个参考位置偏移M个时间单元和N个频域单元，则Q个第一PUSCH传输机会是在频率或时间上连续的Q个，关联同一个下行信号或者同一个PRACH传输机会的PUSCH传输机会，所述时间单元可以是OFDM符号，时隙slot，子帧subframe等，所述频域单元可以子载波，资源块，资源块组等，M或者N可以是网络直接配置的值，或者根据网络配置的PRACH和PUSCH在时频域的复用类型间接确定的。其中频率或时间上连续的Q个传输机会也可以称为一个传输机会包括Q个部分，每一部分可以是一个时间或者频率单元或者一个时频资源。
应该理解的是，上述方法还可以表述为，如果UE确定了随机接入消息的类型为第二随机接入消息，也即只包括preamble，UE只在一个传输机会上发送一次随机接入消息，开始随机接入；如果UE确定随机接入消息的类型为第一随机接入消息，也即需要传输(preamble和PUSCH)，UE可以在多个传输机会发送随机接入消息的不同内容，多个传输机会是P个PRACH和Q个PUSCH的组合；其中Q个PUSCH可以称为包括Q个部分的一个。
其中，P是协议预设的，例如＝2；P个PRACH的位置关系可以是协议预定的，例如频率或者时间上连续的P个对应同一个下行信号的RACH机会。
Q也可以是协议预设的，例如＝4；也可以是根据预设规则或者网络设备配置信息而不同，例如，根据下行信号的测量结果或者传输机会的位置或者网络设备配置的payload确定。当下行信号的测量结果低于某个阈值，表示当前覆盖较差，PUSCH需要重复传输4次，则UE会选择4个连续的PUSCH传输机会；当payload超过某个阈值，表示传输当前PUSCH需要较多的传输资源，则UE会选择4个连续的PUSCH传输机会。
其中，P和Q还可以均为1。应该理解的是P和Q还可以为其他任何可以满足发送需求的值。
可选的，上述方法中的多个第一传输机会还可以结合第二预设规则进行选择，例如，UE不希望Q个PUSCH的第一个或者任何PUSCH与其他上行传输在时间上部分重叠；如果重叠，可能会优先发送PUSCH，丢掉其他上行传输。或者，UE不希望Q个PUSCH的除第一个之外的PUSCH与其他上行传输在时间上部分重叠；如果重叠，可能会优先发送其他上行传输，丢掉除第一个PUSCH之外的其他PUSCH，或者丢掉除第一个PUSCH之外的其他PUSCH中与其他上行传输冲突的部分PUSCH。或者，UE不希望Q个PUSCH所在的多个PUSCH的起始至结束的期间，与其他上行传输在时间上部分重叠，或者时间差满足某种函数关系；如果发生这种情况，UE可能丢掉其他上行传输，或者认为当前传输机会不能作为实际发送随机接入消息的传输机会，UE在该传输机会上不发送随机接入消息。
应当指出，在多个传输机会传输随机接入消息的目的是提高初始接入成功率。然而，在描述上，可以将满足某种预设规则的多个传输机会，定义为一个传输机会。在这种情况下，随机接入消息的内容，也即preamble和/或者PUSCH实际上被传输了多次，达到同样的技术效果。
通过上述方法，提高了提高第一种随机接入的传输可靠性。
