Description

控制UE的随机接入功率的方法、UE及计算机存储介质 技术领域
本发明涉及信息处理技术领域，尤其涉及一种控制用户设备(UE)的随机接入功率的方法、用户设备(UE)及计算机存储介质。
背景技术
当前，在NR中，系统广播信息分成最小系统信息MSI(minimum system information)和其他系统信息OSI(other system information)，其中OSI可以基于UE请求，网络侧才下发的方式，而不是传统的都周期性广播。对于UE的请求，可以通过随机接入过程的MSG1或者MSG3来指示网络侧请求OSI。
对于移动速度很高的UE，为了UE进行快速的邻区选择，需要尽快获取OSI来满足idle移动性需求。对于切换场景，高速移动的UE也需快速进行切换来满足切换的性能需求。因此，所以对于高速UE缩短随机接入的时间很有必要。
发明内容
为解决上述技术问题，本发明实施例提供了一种控制用户设备(UE)的随机接入功率的方法、用户设备(UE)及计算机存储介质。

从所述系统广播信息中，获取与所述UE速度对应的缩放因子；其中，所述UE速度对应的缩放因子包括以下至少之一：UE进行随机接入的功率 调整参数、功率攀升步长调整参数、随机接入回退的调整参数；
基于所述UE速度所对应的缩放因子，对所述UE的随机接入过程中的功率进行修正以及对随机接入过程中前导码发送时刻进行修正。

本发明实施例提供的一种用户设备UE，包括：处理器和用于存储能够在处理器上运行的计算机程序的存储器，
其中，所述处理器用于运行所述计算机程序时，执行前述方法的步骤。
本发明实施例提供的一种计算机存储介质，所述计算机存储介质存储有计算机可执行指令，所述计算机可执行指令被执行时实现前述方法步骤。
本发明实施例的技术方案，就能够基于UE的速度来确定对应的缩放因子，进而基于缩放因子中UE进行随机接入的功率调整参数、功率攀升步长调整参数、随机接入回退的调整参数的至少一种参数来进行随机接入的处理。如此，就能够使得随机接入的过程与UE的速度相结合，从而实现调整随机接入过程的进度快慢，达到快速接入网络，提高移动鲁棒性的目的。
附图说明
图1为本发明实施例提供的一种控制UE的随机接入功率的方法流程示意图；
图2为本发明实施例用户设备组成结构示意图；
图3为本发明实施例的一种硬件架构示意图。
具体实施方式
为了能够更加详尽地了解本发明实施例的特点与技术内容，下面结合附图对本发明实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本发明实施例。
实施例一、
本发明实施例提供了一种控制UE的随机接入功率的方法，应用于UE，如图1所示，所述方法包括：
步骤101：接收网络侧发来的系统广播信息；
步骤102：从所述系统广播信息中，获取与所述UE速度对应的缩放因子；其中，所述UE速度对应的缩放因子包括以下至少之一：UE进行随机接入的功率调整参数、功率攀升步长调整参数、随机接入回退的调整参数；
步骤103：基于所述UE速度所对应的缩放因子，对所述UE的随机接入过程中的功率进行修正以及对随机接入过程中前导码发送时刻进行修正。
首先，UE会接收到网络侧下发的信息，具体可以包括：网络侧，通过系统广播来广播基于UE速度的的缩放因子；
其中，所述UE进行随机接入的功率调整参数，包括：所述UE进行随机接入的初始发送前导码的接收目标功率的因子或者偏置；
所述功率攀升步长调整参数，包括：所述UE进行随机接入时的功率攀升步长的因子或者偏置；
所述随机接入回退的调整参数，包括：随机接入回退的因子或者偏置。
具体的，所述缩放因子中，至少包括有以下之一：用于随机接入的UE初始发送前导码PREAMBLE的接收目标功率的因子或者偏置、者随机接入功率攀升步长的因子或者偏置、随机接入回退的因子或者偏置。
还可以理解的是，网络侧下发的可以为一系列的缩放因子，也就是多 个UE速度、或者多种UE速度范围所对应的不同的缩放因子，然后UE可以根据自身当前的移动速度来选取对应的缩放因子作为本次进行随机接入修正的缩放因子，也就是如下：
所述获取与所述UE速度对应的缩放因子，包括：
所述UE基于移动速度确定其对应的速度范围；
基于所述UE所对应的速度范围，选取对应的缩放因子。
这里，UE速度可以是相对值，也可以是绝对UE速度值或者范围，对应一个缩放因子或者偏置。例如，相对速度，例如UE移动状态，正常，中速，高速分别对应一个缩放因子或者偏置。UE判断是那个速度等级决定是那个因子。绝对速度范围，例如a km/h到b km/h，对应一个缩放因子或者偏置，UE根据自己的实际速度来决定使用那个缩放因子或者偏置。
关于如何使用前述缩放因子中的各种参数下面进行具体说明：
第一种、修正初始发送前导码的接收目标功率：
所述基于所述UE速度所对应的缩放因子，对所述UE的随机接入过程中的功率进行修正，包括：
基于UE随机接入的初始发送前导码的接收目标功率、与进行随机接入的初始发送前导码的接收目标功率的因子相乘，得到修正后的初始发送前导码的接收目标功率。
或者，
基于UE随机接入的初始发送前导码的接收目标功率、与进行随机接入的初始发送前导码的接收目标功率的偏置相加，得到修正后的初始发送前导码的接收目标功率。
也就是说，UE在随机接入过程中修正随机接入的UE初始发送preamble的接收目标功率，随机接入的UE初始发送PREAMBLE的接收目标功率修正为：系统广播里面广播的随机接入的UE初始发送PREAMBLE的接收目 标功率x随机接入的UE初始发送PREAMBLE的接收目标功率的因子，或者系统广播里面广播的随机接入的UE初始发送PREAMBLE的接收目标功率+随机接入的UE初始发送PREAMBLE的接收目标功率的偏置。
第二种、修正UE进行随机接入时的功率攀升步长：
所述基于所述UE速度所对应的缩放因子，对所述UE的随机接入过程中的功率进行修正，包括：
基于UE进行随机接入时的功率攀升步长、与UE进行随机接入时的功率攀升步长的因子相乘，得到修正后的UE进行随机接入时的功率攀升步长。
或者，
基于UE进行随机接入时的功率攀升步长、与UE进行随机接入时的功率攀升步长的偏置相加，得到修正后的UE进行随机接入时的功率攀升步长。
这里功率攀升步长，可以理解为UE在随机接入过程中修正随机接入的功率攀升步长。相应的，UE在随机接入过程中修正随机接入的功率攀升步长，随机接入的功率攀升步长修正为：系统广播里面广播的随机接入的功率攀升步长x随机接入功率攀升步长的因子，或者系统广播里面广播的随机接入的功率攀升步长+随机接入功率攀升步长的偏置。
第三种、修正随机接入回退值：
这种修正处理中，可以包括两种方式，第一种方式：基于网络侧指示的随机接入回退、与随机接入回退的因子相乘得到修正后的随机接入回退参考值；或者，基于网络侧指示的随机接入回退与随机接入回退的偏置相加得到修正后的随机接入回退参考值；
根据修正后的随机接入回退参考值，产生修正后的随机接入回退值；其中，所述修正后的随机接入回退值大于零、且小于所述修正后的随机接 入回退参考值。
也就是说，UE在随机接入过程中修正随机接入回退，随机接入回退参考值为：RAR中指示的随机接入回退x随机接入回退的因子，或者RAR中指示的随机接入回退+随机接入回退的偏置；
然后，根据修正后的随机接入回退参考值，随机产生一个0到修正后的随机接入回退值之间的随机接入回退值。
第二种方式：
基于随机产生的随机接入回退与随机接入回退的因子相乘得到修正后的随机接入回退；
或者，基于随机产生的随机接入回退与随机接入回退的偏置相加得到修正后的随机接入回退。
与第一种方式不同之处在于，这种方式直接计算得到随机接入回退，也就是说，UE在随机接入过程中修正随机接入回退，随机接入回退修正为：随机产生的随机接入回退x随机接入回退的因子，或者随机产生的随机接入回退+随机接入回退的偏置。
基于前面的介绍，可以得到修正后的初始发送前导码的接收目标功率、修正后的UE进行随机接入时的功率攀升步长、修正后的随机接入回退来进行随机接入中前导码的发送处理，具体的：
基于修正后的初始发送前导码的接收目标功率、修正后的UE进行随机接入时的功率攀升步长中至少之一，确定前导码的发射功率；以及基于修正后的随机接入回退确定前导码的发送时刻。
也就是说，可以基于修正后的前导码的接收目标功率以及修正后的UE进行随机接入时的功率攀升步长进行相加，得到前导码发射功率。当然，还可以存在其他的处理方式，这里不再进行穷举。
可见，通过采用上述方案，就能够基于UE的速度来确定对应的缩放因 子，进而基于缩放因子中UE进行随机接入的功率调整参数、步长调整参数、随机接入回退的调整参数的至少一种参数来进行随机接入的处理。如此，就能够使得随机接入的过程与UE的速度相结合，从而实现调整随机接入过程的进度快慢，达到快速接入网络，提高移动鲁棒性的目的。
实施例二、
本发明实施例提供了一种UE，如图2所示，所述方法包括：
通信单元21，接收网络侧发来的系统广播信息；
处理单元22，从所述系统广播信息中，获取与所述UE速度对应的缩放因子；其中，所述UE速度对应的缩放因子包括以下至少之一：UE进行随机接入的功率调整参数、步长调整参数、随机接入回退的调整参数；,基于所述UE速度所对应的缩放因子，对所述UE的随机接入过程中的功率进行修正以及对随机接入过程中前导码发送时刻进行修正。
首先，UE会接收到网络侧下发的信息，具体可以包括：网络侧，通过系统广播来广播基于UE速度的的缩放因子；
其中，所述UE进行随机接入的功率调整参数，包括：所述UE进行随机接入的初始发送前导码的接收目标功率的因子或者偏置；
所述步长调整参数，包括：所述UE进行随机接入时的功率攀升步长的因子或者偏置；
所述随机接入回退的调整参数，包括：随机接入回退的因子或者偏置。
具体的，所述缩放因子中，至少包括有以下之一：用于随机接入的UE初始发送前导码PREAMBLE的接收目标功率的因子或者偏置、者随机接入功率攀升步长的因子或者偏置、随机接入回退的因子或者偏置。
还可以理解的是，网络侧下发的可以为一系列的缩放因子，也就是多个UE速度、或者多种UE速度范围所对应的不同的缩放因子，然后UE可以根据自身当前的移动速度来选取对应的缩放因子作为本次进行随机接入 修正的缩放因子，也就是如下：
所述处理单元22，基于移动速度确定其对应的速度范围；
基于所述UE所对应的速度范围，选取对应的缩放因子。
这里，UE速度可以是相对值，也可以是绝对UE速度值或者范围，对应一个缩放因子或者偏置。例如，相对速度，例如UE移动状态，正常，中速，高速分别对应一个缩放因子或者偏置。UE判断是那个速度等级决定是那个因子。绝对速度范围，例如a km/h到b km/h，对应一个缩放因子或者偏置，UE根据自己的实际速度来决定使用那个缩放因子或者偏置。
关于如何使用前述缩放因子中的各种参数下面进行具体说明：
第一种、修正初始发送前导码的接收目标功率：
所述处理单元22，基于UE随机接入的初始发送前导码的接收目标功率、与进行随机接入的初始发送前导码的接收目标功率的因子相乘，得到修正后的初始发送前导码的接收目标功率。
或者，
基于UE随机接入的初始发送前导码的接收目标功率、与进行随机接入的初始发送前导码的接收目标功率的偏置相加，得到修正后的初始发送前导码的接收目标功率。
也就是说，UE在随机接入过程中修正随机接入的UE初始发送preamble的接收目标功率，随机接入的UE初始发送PREAMBLE的接收目标功率修正为：系统广播里面广播的随机接入的UE初始发送PREAMBLE的接收目标功率x随机接入的UE初始发送PREAMBLE的接收目标功率的因子，或者系统广播里面广播的随机接入的UE初始发送PREAMBLE的接收目标功率+随机接入的UE初始发送PREAMBLE的接收目标功率的偏置。
第二种、修正UE进行随机接入时的功率攀升步长：
所述处理单元22，基于UE进行随机接入时的功率攀升步长、与UE 进行随机接入时的功率攀升步长的因子相乘，得到修正后的UE进行随机接入时的功率攀升步长。
或者，
基于UE进行随机接入时的功率攀升步长、与UE进行随机接入时的功率攀升步长的偏置相加，得到修正后的UE进行随机接入时的功率攀升步长。
这里功率攀升步长，可以理解为UE在随机接入过程中修正随机接入的功率攀升步长。相应的，UE在随机接入过程中修正随机接入的功率攀升步长，随机接入的功率攀升步长修正为：系统广播里面广播的随机接入的功率攀升步长x随机接入功率攀升步长的因子，或者系统广播里面广播的随机接入的功率攀升步长+随机接入功率攀升步长的偏置。
第三种、修正随机接入回退值：
这种修正处理中，可以包括两种方式，第一种方式：处理单元22，基于网络侧指示的随机接入回退、与随机接入回退的因子相乘得到修正后的随机接入回退参考值；或者，基于网络侧指示的随机接入回退与随机接入回退的偏置相加得到修正后的随机接入回退参考值；
根据修正后的随机接入回退参考值，产生修正后的随机接入回退值；其中，所述修正后的随机接入回退值大于零、且小于所述修正后的随机接入回退参考值。
也就是说，UE在随机接入过程中修正随机接入回退，随机接入回退参考值为：RAR中指示的随机接入回退x随机接入回退的因子，或者RAR中指示的随机接入回退+随机接入回退的偏置；
然后，根据修正后的随机接入回退参考值，随机产生一个0到修正后的随机接入回退值之间的随机接入回退值。
第二种方式：
处理单元22，基于随机产生的随机接入回退与随机接入回退的因子相乘得到修正后的随机接入回退；
或者，基于随机产生的随机接入回退与随机接入回退的偏置相加得到修正后的随机接入回退。
与第一种方式不同之处在于，这种方式直接计算得到随机接入回退，也就是说，UE在随机接入过程中修正随机接入回退，随机接入回退修正为：随机产生的随机接入回退x随机接入回退的因子，或者随机产生的随机接入回退+随机接入回退的偏置。
基于前面的介绍，可以得到修正后的初始发送前导码的接收目标功率、修正后的UE进行随机接入时的功率攀升步长、修正后的随机接入回退来进行随机接入中前导码的发送处理，具体的：
处理单元22，基于修正后的初始发送前导码的接收目标功率、修正后的UE进行随机接入时的功率攀升步长中至少之一，确定前导码的发射功率；以及基于修正后的随机接入回退确定前导码的发送时刻。
也就是说，可以基于修正后的前导码的接收目标功率以及修正后的UE进行随机接入时的功率攀升步长进行相加，得到前导码发射功率。当然，还可以存在其他的处理方式，这里不再进行穷举。
可见，通过采用上述方案，就能够基于UE的速度来确定对应的缩放因子，进而基于缩放因子中UE进行随机接入的功率调整参数、步长调整参数、随机接入回退的调整参数的至少一种参数来进行随机接入的处理。如此，就能够使得随机接入的过程与UE的速度相结合，从而实现调整随机接入过程的进度快慢，达到快速接入网络，提高移动鲁棒性的目的。
