具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例， 都属于本申请保护的范围。
为了解决高频范围很大系统的接入需求，本公开实施例通过在配置信息中包含用于指示随机接入的不同策略，即对于相对低频的系统可以采用第一策略，对于相对高频的系统可以采用第二策略(此处的低频和高频是相对概念，例如50GHZ相对于60GHZ是低频，但二者均属于高频)，从而使得用户设备(UE)可以根据接收的配置信息确定自己随机接入所采用的策略，并确定与所采用的策略对应的上行物理随机接入信道(PRACH)资源，然后基于所确定的上行PRACH资源向基站发送前导序列。下面将结合实施例进行详细描述。
图1是本申请一示例性实施例示出的一种随机接入方法的流程图，该实施例从UE侧进行描述，如图1所示，该随机接入方法包括：
在步骤S101中，根据接收的配置信息确定当前UE随机接入所采用的策略，该配置信息中包含用于指示随机接入的不同策略。
其中，指示随机接入的不同策略可以包括系统工作频段及随机接入所对应采用的策略，例如，系统工作频段为6-20GHZ时，随机接入所对应采用的策略为第一策略，系统工作频段为20-60GHZ时，随机接入所对应采用的策略为第二策略。由于配置信息中包含系统工作频段及随机接入所对应采用的策略，因此，对于高频范围很大的系统，可以根据其工作频段来确定当前UE随机接入所采用的策略。
上述6-20GHZ、20-60GHZ仅为举例，在实际应用中可以根据需要灵活设置不同策略对应的工作频段。
另外，在执行上述步骤S101之前，UE可以预先接收基站发送的上述配置信息。
在步骤S102中，确定与所采用的策略对应的PRACH资源。
当所采用的策略为第一策略时，与所采用的策略对应的上行物理随机接入信道PRACH资源可以包括：第一波束和前导序列码资源集合。当所采用的策略为第二策略时，与所采用的策略对应的上行物理随机接入信道PRACH资源可以包括：第一波束、第二波束和前导序列码资源集合，其中，第一波束和第二波束相邻且均与下行信号同步块的波束相对应。
需要说明的是，上述第一策略和第二策略用于表示二者是不同的策略，类似地，第一波束和第二波束用于表示二者是不同的波束且二者相邻。
在步骤S103中，基于所确定的上行PRACH资源向基站发送前导序列。
当所采用的策略为第一策略时，UE可以从前导序列码资源集合中选择一个前导序列码， 并在第一波束上向基站发送与前导序列码对应的前导序列。当所采用的策略为第二策略时，UE可以从前导序列码资源集合中选择一个前导序列码，并分别在第一波束上和第二波束上向基站发送与前导序列码对应的前导序列。
由此可见，对于第一策略，UE发送了一个前导序列，对于第二策略，UE在两个相邻的波束上分别发送了一个前导序列，即共发送了两个前导序列。由于系统工作频率越高，信号衰减越大，随机接入成功率越低，而本公开通过发送两个前导序列的方式可以大大提高随机接入的成功率。
上述实施例，通过在配置信息中包含用于指示随机接入的不同策略，使得用户设备(UE)可以根据接收的配置信息确定自己随机接入所采用的策略，并确定与所采用的策略对应的上行PRACH资源，然后基于所确定的上行PRACH资源向基站发送前导序列，很好地解决了高频范围很大系统的配置需求和接入需求。
图2是本申请一示例性实施例示出的另一种随机接入方法的流程图，如图2所示，该随机接入方法包括：
在步骤S200中，根据接收的配置信息确定当前UE随机接入所采用的策略。
在步骤S201中，判断所采用的策略为第一策略还是第二策略，若所采用的策略为第一策略，则执行步骤S202，若所采用的策略为第二策略，则执行步骤S203。
在步骤S202中，确定与第一策略对应的上行PRACH资源包括第一波束和前导序列码资源集合，并执行步骤S204。
在步骤S203中，确定与第二策略对应的上行PRACH资源包括第一波束、第二波束和前导序列码资源集合，并执行步骤S205。
在步骤S204中，从前导序列码资源集合中选择一个前导序列码，并在第一波束上向基站发送与前导序列码对应的前导序列，并执行步骤S206。
在步骤S205中，从前导序列码资源集合中选择一个前导序列码，并分别在第一波束上和第二波束上向基站发送与前导序列码对应的前导序列，并执行步骤S207。
其中，前导序列码资源集合可以包括第一前导序列码资源集合和第二前导序列码资源集合。在该实施例中，除了可以通过步骤S205所示的方式发送前导序列，还可以采用以下方式发送前导序列：从第一前导序列码资源集合中选择第一前导序列码，并在第一波束上向基站发送与第一前导序列码对应的第一前导序列，以及从第二前导序列码资源集合中选择第二前 导序列码，并在第二波束上向基站发送与第二前导序列码对应的第二前导序列。
由于在发送前导序列之前可以测量上述第一波束和第二波束的接收功率，假设第一波束的接收功率大于第二波束的接收功率，则可以在第一波束上以较大功率发送第一前导序列，在第二波束上以较小功率发送第二前导序列，以达到提高当前UE接入成功率的同时减少对其他UE随机接入的干扰。
在步骤S206中，若未接收到随机接入响应消息，则在第三波束上向基站发送前导序列，并执行步骤S208。
其中，第三波束与第一波束不同，需要说明的是，第三波束用于表示与第一波束不同的波束，即可以为除第一波束之外的任意波束。
在步骤S207中，若未接收到随机接入响应消息，则增大第一波束和第二波束的发射功率，并分别在发射功率增大后的第一波束和第二波束上向基站发送前导序列，操作结束。
在步骤S208中，若仍未接收到随机接入响应消息，则增大第一波束的发射功率，并在发射功率增大后的第一波束上向基站发送前导序列。
在步骤S209中，若仍未接收到随机接入响应消息，则增大第四波束的发射功率，并在发射功率增大后的第四波束上向基站发送前导序列。
第四波束与第一波束不同，需要说明的是，第四波束用于表示与第一波束不同的波束，即可以为除第一波束之外的任意波束。
UE在前导序列发送失败后，首先进行波束调整，如果仍然发送失败，则对原波束即第一波束进行功率提升，如果还是发送失败，则再更换波束且同时提升功率。
上述实施例，通过描述UE在不同策略下的随机接入过程，很好地解决了高频范围很大系统的接入需求。
图3是本申请一示例性实施例示出的另一种随机接入方法的流程图，如图3所示，在上述步骤S205之后，该随机接入方法还可以包括：
在步骤S210中，若接收到两个随机接入响应消息，则获取两个随机接入响应消息的功率测量值。
在步骤S211中，确定功率测量值大的随机接入响应消息对应的波束，丢弃功率测量值小的随机接入响应消息，并在所确定的波束上向基站发送连接建立请求。
在该实施例中，在获取两个随机接入响应消息的功率测量值后，通过比较两个随机接 入响应消息的功率测量值的大小，并丢弃功率测量值小的随机接入响应消息，而在功率测量值大的随机接入响应消息对应的波束上向基站发送连接建立请求，即只发送一个连接建立请求，从而提高随机接入成功率。
上述实施例，通过丢弃功率测量值小的随机接入响应消息，而在功率测量值大的随机接入响应消息对应的波束上向基站发送连接建立请求，从而提高随机接入成功率。
图4是根据一示例性实施例示出的一种随机接入装置的框图，如图4所示，该装置包括：第一确定模块41、第二确定模块42和发送模块43。
第一确定模块41被配置为根据接收的配置信息确定当前UE随机接入所采用的策略，配置信息中包含用于指示随机接入的不同策略。
其中，指示随机接入的不同策略可以包括系统工作频段及随机接入所对应采用的策略，例如，系统工作频段为6-20GHZ时，随机接入所对应采用的策略为第一策略，系统工作频段为20-60GHZ时，随机接入所对应采用的策略为第二策略。由于配置信息中包含系统工作频段及随机接入所对应采用的策略，因此，对于高频范围很大的系统，可以根据其工作频段来确定当前UE随机接入所采用的策略。
上述6-20GHZ、20-60GHZ仅为举例，在实际应用中可以根据需要灵活设置不同策略对应的工作频段。
第二确定模块42被配置为确定与第一确定模块41确定的所采用的策略对应的上行物理随机接入信道PRACH资源。
当所采用的策略为第一策略时，与所采用的策略对应的上行物理随机接入信道PRACH资源可以包括：第一波束和前导序列码资源集合。当所采用的策略为第二策略时，与所采用的策略对应的上行物理随机接入信道PRACH资源可以包括：第一波束、第二波束和前导序列码资源集合，其中，第一波束和第二波束相邻且均与下行信号同步块的波束相对应。
需要说明的是，上述第一策略和第二策略用于表示二者是不同的策略，类似地，第一波束和第二波束用于表示二者是不同的波束且二者相邻。
发送模块43被配置为基于第二确定模块42所确定的上行PRACH资源向基站发送前导序列。
当所采用的策略为第一策略时，UE可以从前导序列码资源集合中选择一个前导序列码，并在第一波束上向基站发送与前导序列码对应的前导序列。当所采用的策略为第二策略 时，UE可以从前导序列码资源集合中选择一个前导序列码，并分别在第一波束上和第二波束上向基站发送与前导序列码对应的前导序列。
由此可见，对于第一策略，UE发送了一个前导序列，对于第二策略，UE在两个相邻的波束上分别发送了一个前导序列，即共发送了两个前导序列。由于系统工作频率越高，信号衰减越大，随机接入成功率越低，而本公开通过发送两个前导序列的方式可以大大提高随机接入的成功率。
如图4所示的装置用于实现上述如图1所示的方法流程，涉及到的相关内容描述相同，此处不赘述。
上述实施例，通过在配置信息中包含用于指示随机接入的不同策略，使得用户设备(UE)可以根据接收的配置信息确定自己随机接入所采用的策略，并确定与所采用的策略对应的上行PRACH资源，然后基于所确定的上行PRACH资源向基站发送前导序列，很好地解决了高频范围很大系统的配置需求和接入需求。

其中，第三波束与第一波束不同，需要说明的是，第三波束用于表示与第一波束不同的波束，即可以为除第一波束之外的任意波束。
在另一实施例中，第一发送子模块431还可以被配置为在在第三波束上向基站发送前导序列之后，若仍未接收到随机接入响应消息，则增大第一波束的发射功率，并在发射功率 增大后的第一波束上向基站发送前导序列。
在另一实施例中，第一发送子模块431还可以被配置为在在发射功率增大后的第一波束上向基站发送前导序列之后，若仍未接收到随机接入响应消息，则增大第四波束的发射功率，并在发射功率增大后的第四波束上向基站发送前导序列，第四波束与第一波束不同。
