Description

用于接收和发送系统消息的方法、装置、用户设备及基站 技术领域
本公开涉及通信技术领域，尤其涉及一种用于接收和发送系统消息的方法、装置、用户设备及基站。
背景技术
随着无线通信技术的飞速发展，长期演进(Long Term Evolution，简称为LTE)的系统消息(System Information，简称为SI)数目增多，采用周期性广播的方式发送LTE的系统消息使得基站的功耗较大，频谱资源利用率较低。对于接入的用户设备(User Equipment，简称为UE)数目比较少的情况，周期性广播发送LTE的系统消息存在资源浪费的问题。为了缓解广播发送LTE的系统消息所带来的资源浪费和基站功耗较大的问题，运营商开始考虑通过分类发送系统消息的方式来解决上述问题。
相关技术中，在第五代移动通信技术(5th Generation，简称为5G)项目的研究讨论中，可将系统消息分为第一类系统消息和第二类系统消息，第一类系统消息可包含小区选择与接入的相关系统消息，第二类系统消息可包含除第一类系统消息之外的其他系统消息。相关技术中，可通过广播发送第一类系统消息，可基于UE的请求来广播发送或单播发送第二类系统消息。

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。
图1是本申请一示例性实施例示出的一种用于接收系统消息的方法的流程图，该实施例从UE侧进行描述，如图1所示，用于接收系统消息的方法包括：
在步骤S101中，向基站发送第一SI请求，该第一SI请求用于请求基站广播发送至少一个待请求SI，至少一个待请求SI属于未广播的第二类SI。
在该实施例中，如图2所示，在执行步骤S101之前，该方法还可以包括：
在步骤S100中，接收基站广播发送的第一类SI，该第一类SI中携带有未广播的第二类SI。
在该实施例中，第一类SI可以为Minimum SI，第二类SI可以为除Minimum SI之外的其他(other)SI。其中，基站可以在广播的第一类SI中携带未广播的第二类SI，以方便UE在需要获取其中某个或某些未广播的第二类SI时，向基站发送第一SI请求，以请求基站广播发送至少一个待请求SI。
另外，第一类SI中还可以携带有指示信息，该指示信息可以包括以下信息中的至少一项：统一指示或分别指示的与每个第二类SI相对应的请求次数，统一指示或分别指示的与每个第二类SI相对应的监听窗口数量，统一指示或分别指示的与每个第二类SI相对应的译码失败次数，以及可转单播的第二类SI。
在步骤S102中，根据预先获取的调度信息接收基站根据第一SI请求广播发送的至少一个待请求SI。
其中，UE可以通过与基站约定的方式获取调度信息，并根据该调度信息去接收基站根据第一SI请求广播发送的至少一个待请求SI。
在步骤S103中，若确定未成功接收到任意一个或多个待请求SI，则向基站发送第二SI请求，该第二SI请求用于请求基站单播发送当前UE未成功接收到的待请求SI。
如果UE未能成功接收到任意一个或多个待请求SI，则可以向基站发送第二SI请求，以请求基站单播发送当前UE未成功接收到的待请求SI。其中，UE可以在向基站发送的连接建立请求中携带第二SI请求，也可以在向基站发送的前导序列中携带第二SI请求。
在该实施例中，第二SI请求可以指示基站以单播的方式发送待请求SI，例如，可以针对每个待请求SI分别指示，也可以针对所有待请求SI统一指示。
另外，若指示信息中包括可转单播的第二类SI，则UE需要确认当前UE未成功接收到的待请求SI是否属于可转单播的第二类SI，若属于，则可以向基站发送第二SI请求。
在步骤S104中，接收基站根据第二SI请求单播发送的当前UE未成功接收到的待请求SI。
基站在接收到UE通过前导序列或连接建立请求中携带的第二SI请求后，可以在对应的响应消息中将当前UE未成功接收到的待请求SI发送给UE。
上述实施例，在确定未成功接收到基站广播的任意一个或多个待请求SI后，通过向 基站发送第二SI请求，使得基站可以根据该第二SI请求单播发送当前UE未成功接收到的待请求SI，从而使得UE可以成功获取对应的待请求SI。
图3是本申请一示例性实施例示出的一种根据调度信息接收基站广播发送的至少一个待请求SI的流程图，在该实施例中，调度信息可以包括起始监听窗口位置和窗口数量，如图3所示，根据调度信息接收基站广播发送的至少一个待请求SI的过程可以包括：
在步骤S301中，针对每个待请求SI，自当前待请求SI的起始监听窗口位置对应的起始监听窗口起连续监听当前待请求SI对应的窗口数量接收窗口。
其中，每个SI的起始监听窗口位置和窗口数量可以由UE和基站约定。
另外，如果第一类SI中携带指示信息，则窗口数量可以等于指示信息中的监听窗口数量。
假设待请求SI为SI1和SI2，窗口数量为5个，则对于SI1，可以自SI1的起始监听窗口位置对应的起始监听窗口起连续监听5个接收窗口，对于SI2，可以自SI2的起始监听窗口位置对应的起始监听窗口起连续监听5个接收窗口。
在步骤S302中，判断在连续监听的接收窗口内是否接收到当前待请求SI，若在连续监听的接收窗口内未接收到当前待请求SI，则确定未成功接收到当前待请求SI，若在连续监听的接收窗口内接收到当前待请求SI，则执行步骤S303。
继续上例进行描述，若在5个接收窗口内未接收到SI1，则确定未成功接收到SI1，若在5个接收窗口内未接收到SI2，则确定未成功接收到SI2。
在步骤S303中，在对应接收窗口内对当前待请求SI进行译码。
在步骤S304中，统计在对应接收窗口内对当前待请求SI译码失败的次数。
在步骤S305中，若该次数达到译码失败次数阈值，则确定未成功接收到当前待请求SI。
需要说明的是，上述步骤S303至步骤S305为可选步骤，若上述过程包括步骤S303至步骤S305，则调度信息还可以包括译码失败次数阈值。其中，译码失败次数阈值可以由UE和基站约定。另外，如果第一类SI中携带指示信息，则译码失败次数阈值可以等于指示信息中的译码失败次数。
上述实施例，通过连续监听接收窗口来接收待请求SI，以在未成功接收到待请求SI后，通过向基站发送第二SI请求来请求基站单播发送对应SI，以提高接收成功率；另外，还 可以通过统计在对应接收窗口内对当前待请求SI译码失败的次数，并在该次数达到译码失败次数阈值时，确定未成功接收到当前待请求SI，然后通过向基站发送第二SI请求来请求基站单播发送对应SI，以提高接收成功率。
图4是本申请一示例性实施例示出的另一种根据调度信息接收基站广播发送的至少一个待请求SI的流程图，在该实施例中，调度信息还可以包括请求次数阈值，如图4所示，在上述步骤S302中的确定未成功接收到当前待请求SI之后，根据调度信息接收基站广播发送的至少一个待请求SI还可以包括：
在步骤S306中，向基站发送第三SI请求，并记录请求次数，该第三SI请求用于请求基站广播发送当前待请求SI。
在步骤S307中，自当前待请求SI的起始监听窗口位置对应的起始监听窗口起连续监听当前待请求SI对应的窗口数量接收窗口。
在步骤S308中，判断记录的请求次数是否达到请求次数阈值且在连续监听的接收窗口内是否接收到当前待请求SI，若记录的请求次数未达到请求次数阈值且在连续监听的接收窗口内未接收到当前待请求SI，则转向执行步骤S306；若记录的请求次数未达到请求次数阈值且在连续监听的接收窗口内接收到当前待请求SI，则转向执行步骤S303；若记录的请求次数达到请求次数阈值且在连续监听的接收窗口仍未接收到当前待请求SI，则确定未成功接收到当前待请求SI；若记录的请求次数达到请求次数阈值且在连续监听的接收窗口接收到当前待请求SI，则转向执行步骤S303。
其中，请求次数阈值可以由UE和基站约定。
另外，如果第一类SI中携带指示信息，则请求次数阈值可以等于指示信息中的请求次数。
上述实施例，通过向基站发送第三SI请求，并通过连续监听接收窗口来接收待请求SI，以在请求次数达到请求次数阈值后仍未成功接收到待请求SI的情况下，通过向基站发送第二SI请求来请求基站单播发送对应SI，以提高接收成功率；另外，还可以通过统计在对应接收窗口内对当前待请求SI译码失败的次数，并在该次数达到译码失败次数阈值时，确定未成功接收到当前待请求SI，然后通过向基站发送第二SI请求来请求基站单播发送对应SI，以提高接收成功率。
