为了便于理解本申请实施例提供的方案，下面先对随机接入进行介绍。
三、随机接入
随机接入主要分为竞争性随机接入和非竞争性随机接入。
竞争性随机接入：终端设备从与其他终端设备共享的前导码池中随机选择前导码。从而会出现两个终端设备选择的前导码相同的情况，并且可能造成冲突或竞争。网络设备使用竞争解决机制来处理该类型的接入请求，流程可参见图2，具体如下：终端设备尝试接入到网络，首先会在随机接入信道((Random Access Channel，RACH)上向网络设备发送随机接入前导码Msg1，该随机接入前导码用于随机接入时识别终端设备身份。网络设备接收到随机接入前导码Msg1后，会在下行共享信道(Uplink Shared Channel，DL-SCH)上返回随机接入响应Msg2，该随机接入响应Msg2中携带了上行授权指令和时间同步调整指令等。终端设备接收到随机接入响应Msg2后，判断是否为属于该终端设备自己的随机接入响应消息，并向网络设备发送连接建立请求Msg3。最后网络设备向终端设备发送RRC连接建立Msg4，若终端设备正确接收Msg4，则完成竞争解决。
非竞争性随机接入：前导码由网络设备分配，这种前导码称为专用随机接入前导码。 该专用随机接入前导码通过(Radio Resource Control，RRC)信令或者物理层信令提供给终端设备。因此不存在签到码冲突。
为了提高终端设备随机接入的成功率，本申请提供了一种随机接入方法、装置、芯片及模组设备。下面进一步对本申请实施例提供的随机接入、装置、芯片及模组设备进行详细描述。
图3是本申请实施例提供的一种随机接入方法的流程示意图。如图3所示，该随机接入方法包括如下步骤301～步骤302。图3所示的方法执行主体可以为终端设备和网络设备。或者，图3所示的方法执行主体可以为终端设备中的芯片和网络设备中的芯片。本申请实施例并不唯一性地限制该方法的执行主体，相应的执行主体也可以是能够提供实施该方法的任一设备、芯片或软件模块，亦或是它们之间的组合。为了方便后续的描述，图3所示的方法执行主体以终端设备和网络设备为例。其中：
301、网络设备向终端设备发送第一信令，该第一信令包括第一字段，该第一字段用于指示第一随机接入信道时机RO资源组，该第一RO资源组包括多个RO资源，第一RO资源组用于重复传输随机接入消息一。相应地，终端设备可接收该第一信令。
其中，第一信令为在终端设备向网络设备发送Msg1之前，该Msg1包括随机接入前导码，由网络设备发送给终端设备的信令。
在一种可能的实施例中，第一信令为物理下行控制信道命令(Physical Downlink Control Channel order，PDCCH order)。其中，PDCCH命令是网络设备向终端设备发送的用于触发终端设备发起随机接入的命令。
在一种可能的实施例中，当第一信令为物理下行控制信道PDCCH命令时，第一字段的名称可以为PRACH掩码索引(PRACH Mask Index)。或者，第一字段的名称也可以为其他名称，本申请实施例不做限定。
在另一种可能的实施例中，第一信令为RRC信令，该第一字段位于该RRC信令中的BFR配置信息元素中。
在一种可能的实现中，第一字段的候选值与RO资源组之间具有对应关系，第一字段的每个候选值均与RO资源组之间具有对应关系，或第一字段的预留候选值与RO资源组之间具有对应关系。
举例来说，假设第一字段为PRACH Mask Index，可以重新定义PRACH Mask Index 与RO资源组之间的关系，或定义PRACH Mask Index中原本预留的候选值与RO资源组之间的关系。原始的PRACH Mask Index中候选值1-8中任一候选值对应一个RO资源，候选值11-15为预留候选值。可重新定义PRACH Mask Index中所有候选值与RO资源之间的关系，以使得一个候选值对应一个RO资源组。例如，如图4所示，第一字段的候选值为0时，对应的第一RO资源组为RO资源组1；第一字段的候选值为1时，对应的第一RO资源组为RO资源组2，以此类推。任一RO资源组中包括1个或者多个RO资源。
或者，保留有原始的PRACH Mask Index中候选值1-8与RO的对应关系，然后定义PRACH Mask Index中的预留候选值11-15，如候选值11对应RO资源组1，候选值12对应RO资源组2，候选值13对应RO资源组3，候选值14对应RO资源组4，候选值15对应RO资源组5。其中，任一RO资源组中可以包括至少两个RO资源。
在一种可能的实施例中，第一字段的候选值与RO资源组之间的对应关系为协议预先规定的。
基于该可能的实现方式，不需要网络设备为终端设备配置相关配置信息，有利于节省传输资源。
在另一种可能的实现中，该方法还包括：网络设备向终端设备发送配置信息，配置信息用于配置第一字段的候选值与RO资源组之间的对应关系。相应地，终端设备还可以接收网络设备发送的配置信息。
在该种可能的实现中，网络设备可以为终端设备配置相关的配置信息，也就是说如图4所示的配置信息不是固定的，可以由网络设备重新发送配置信息进行改变，从而使得配置信息更加灵活。可选的，该配置信息可以由高层信令来承载，如RRC信令或者MAC-CE信令。
在一种可能的实施例中，第一字段通过指示第一同步信号块SSB组来指示第一RO资源组；终端设备还可基于第一SSB组中的SSB与RO之间的对应关系，确定第一RO资源组。
其中，第一SSB组中的SSB与RO之间的对应关系可以是协议预先规定的，也可以是网络设备为终端设备配置的，还可以是其他方式规定的，在此不做限制。例如，第一SSB组中的SSB与RO之间的对应关系如下表1所示：
表1

若第一字段指示的第一SSB组中包括的SSB为SSB1和SSB2，基于表1所示，该SSB1对应的RO资源为RO1和RO2，而SSB2对应的RO资源为RO3和RO4，则第一字段指示的第一RO资源组为包括RO1、RO2、RO3以及RO4的RO资源组。
可选的，随机接入消息一的总重传次数为第一SSB组对应的所有RO资源的数量。
在一种可能的实施例中，第一字段通过指示第一同步信号块SSB来指示第一RO资源组；终端设备还可基于第一SSB中的SSB与RO之间的对应关系，确定第一RO资源组。
其中，第一SSB与RO之间的对应关系可以是协议预先规定的，也可以是网络设备为终端设备配置的，还可以是其他方式规定的，在此不做限制。
示例性的，若第一SSB为SSB1，由于该SSB1对应的RO资源为RO1和RO2，则第一RO资源组包括的RO为RO1和RO2；若第一SSB为SSB2，由于该SSB2对应的RO资源为RO3和RO3，则第一RO资源组包括的RO为RO3和RO4。
可选的，随机接入消息一的总重传次数为第一SSB对应的所有RO资源的数量。
此外，SSB可以与波束之间具有对应关系。例如，如下表2所示：
表2
若SSB为SSB1，则可以确定该SSB1对应的波束1。若一个SSB组中包括的SSB为：SSB1和SSB2，则该SSB组对应的波束为波束1和波束2。也就是说，通过上述表1和表2，可以根据第一字段，确定出对应的多个波束。
302、终端设备基于第一RO资源组对随机接入消息一进行重复传输。相应地，网络设备基于第一RO资源组接收该终端设备传输的随机接入消息一。
本申请实施例中，终端设备可以使用相同或不同的发送波束基于第一RO资源组对随机接入消息一进行重复传输。
下面对终端设备确定随机接入消息一的重复传输次数的几种可能的方式进行介绍。
方式一、第一字段还指示随机接入消息一的重复传输次数；终端设备基于该第一RO资源组对随机接入消息一进行重复传输，具体为：终端设备基于该第一RO资源组和该随机接入消息一的重复传输次数，对随机接入消息一进行重复传输。相应地，网络设备基于该第一RO资源组和该随机接入消息一的重复传输次数接收该终端设备传输的随机接入消息一。
也就是说，终端设备基于第一字段确定随机接入消息一的重复传输次数。第一字段除了指示第一RO资源组以外，还指示随机接入消息一的重复传输次数。
情况1：第一字段的候选值与RO资源组具有对应关系，且第一字段的候选值与重复传输次数具有对应关系。
例如，如下表3所示：
表3
表3中的重复传输次数可以解释为随机接入消息一的总重复传输次数，或者解释为第一字段指示的一个RO资源对应的随机接入消息一的重复传输次数。
若第一字段的候选值为0，则该第一字段指示的第一RO资源组为RO资源组1，该RO资源组1包括的RO为：RO1、RO2，该第一字段指示的总重复传输次数为2。若第一字段的候选值为1，则该第一字段指示的第一RO资源组为RO资源组2，该RO资源组2包括的RO为：RO1、RO3、RO4，该第一字段指示的总重复传输次数为3。若第一字段的候选值为2，则该第一字段指示的第一RO资源组为RO资源组3，该RO资源组3包括的RO为：RO1、RO2、RO3、RO4，该第一字段指示的总重复传输次数为4。
在上述的实现中，第一字段指示的随机接入消息一的重复传输次数是随机接入消息一的总重复传输次数。可选的，第一字段指示的随机接入消息一的重复传输次数为RO资源组中一个RO资源对应的随机接入消息一的重复传输次数。此时，随机接入消息一的总重复传输次数与RO资源组中的RO资源的数量是呈倍数关系的，随机接入消息一的总重复 传输次数可以是RO资源组中的RO资源数量的多倍。例如，假设第一字段指示的随机接入消息一的重复传输次数为2次，RO资源组中的RO资源数量为2，则随机接入消息一的总重复传输次数可以是4。
基于该可能的实现方式，不使用其他字段指示随机接入消息一的重复传输次数，有利于节约指示比特。
情况2：第一字段的候选值与SSB组具有对应关系，且第一字段指示随机接入消息一的重复传输次数。
例如，如下表4所示：
表4
表4中的重复传输次数可以解释为随机接入消息一的总重复传输次数，或者解释为第一字段指示的一个SSB对应的随机接入消息一的重复传输次数。
若第一字段的候选值为0，则该第一字段指示的第一SSB组为SSB组1，该SSB组1包括的SSB为：SSB1、SSB2、SSB3，该第一字段指示的总重复传输次数为2。若第一字段的候选值为1，则该第一字段指示的第一SSB组为SSB组2，该SSB组2包括的SSB为：SSB1、SSB3、SSB4，该第一字段指示的总重复传输次数为3。若第一字段的候选值为2，则该第一字段指示的第一SSB组为SSB组3，该SSB组3包括的SSB为：SSB2、SSB3、SSB4，该第一字段指示的总重复传输次数为4。
在上述的实现中，第一字段指示的随机接入消息一的重复传输次数是随机接入消息一的总重复传输次数。可选的，第一字段指示的随机接入消息一的重复传输次数为SSB组中一个SSB对应的随机接入消息一的重复传输次数。此时，随机接入消息一的总重复传输次数与SSB组中的SSB的数量是呈倍数关系的，随机接入消息一的总重复传输次数可以是SSB组中的SSB数量的多倍。例如，假设第一字段指示的随机接入消息一的重复传输次数为2次，SSB组中的SSB数量为2，则随机接入消息一的总重复传输次数可以是4。
情况3：第一字段的候选值与SSB具有对应关系，且第一字段指示随机接入消息一的 重复传输次数。
例如，如下表5所示：
表5
若第一字段的候选值为0，则该第一字段指示的第一SSB为SSB1，该第一字段指示的总重复传输次数为2。若第一字段的候选值为1，则该第一字段指示的第一SSB为SSB2，该第一字段指示的总重复传输次数为3。若第一字段的候选值为2，则该第一字段指示的第一SSB为SSB3，该第一字段指示的总重复传输次数为4。
方式二、终端设备基于第一SSB组包括的SSB的数量确定随机接入消息一的重复传输次数；终端设备基于第一RO资源组，对随机接入消息一进行重复传输；终端设备还可基于第一RO资源组和随机接入消息一的重复传输次数，对随机接入消息一进行重复传输。相应地，网络设备基于第一RO资源组和随机接入消息一的重复传输次数接收终端设备传输的随机接入消息一。
也就是说，终端设备通过确定第一SSB组包括的SSB的数量来确定随机接入消息一的总重复传输次数。例如，随机接入消息一的总重复传输次数与第一SSB组包括的SSB的数量相同，或者，随机接入消息一的总重复传输次数为第一SSB组包括的SSB的数量的多倍。
基于该可能的实现方式，无需通过字段指示随机接入消息一的重复传输次数，有利于节约传输资源。
方式三、终端设备基于第一字段指示第一RO资源组包括的RO资源的数量确定随机接入消息一的重复传输次数；终端设备基于该第一RO资源组对随机接入消息一进行重复传输；终端设备还可基于该第一RO资源组和该随机接入消息一的重复传输次数，对随机接入消息一进行重复传输。相应地，网络设备基于该第一RO资源组和该随机接入消息一的重复传输次数接收该终端设备传输的随机接入消息一。
也就是说，终端设备通过确定第一RO资源组包括的RO资源的数量来确定随机接入 消息一的总重复传输次数。例如，随机接入消息一的总重复传输次数与第一RO资源组包括的RO资源的数量相同，或者，随机接入消息一的总重复传输次数为第一RO资源组包括的RO资源的数量的多倍。
基于该可能的实现方式，不通过字段指示随机接入消息一的重复传输次数，有利于节约传输资源。
方式四、第一信令还包括第二字段，第二字段用于指示随机接入消息一的重复传输次数；终端设备基于第一RO资源组对随机接入消息一进行重复传输。终端设备基于第一RO资源组，对随机接入消息一进行重复传输，具体为：终端设备基于该第一RO资源组和该随机接入消息一的重复传输次数，对随机接入消息一进行重复传输。相应地，网络设备基于该第一RO资源组和该随机接入消息一的重复传输次数接收该终端设备传输的随机接入消息一。
其中第二字段指示的重复传输次数可以是针对一个SSB或一个RO资源所对应的随机接入消息一的重复传输次数，也可以是总的随机接入消息一的重复传输次数。
相比于上述的方式，该方式采用单独的字段指示随机接入消息一的重复传输次数，而非联合指示，能够更加灵活地指示重复传输次数。
