参见图1,图中示出了本公开一个实施例中的上行发送功率控制方法的流程,该方法的执行主体可以是终端,例如:手机、平板电脑(Tablet Personal Computer)、膝上型电脑(Laptop Computer)、个人数字助理(personal digital assistant,简称PDA)、移动上网装置(Mobile Internet Device,MID)或可穿戴式设备(Wearable Device)等。具体步骤如下:
步骤101、UE发送第一系统信息请求失败后,确定额外增加的上行发送功率;
步骤102、UE根据发送第一系统信息请求的第一上行发送功率和额外增加的上行发送功率,确定发送第二系统信息请求的第二上行发送功率。
需要说明的是,上述第一系统信息请求和第二系统信息请求可以称为上一次系统信息请求和下一次系统信息请求。
在本实施例中,可以在UE发送系统信息请求失败后,通过提升系统信息请求的上行发送功率,提高系统信息请求的发送成功率。
参见图2,图中示出了本公开另一个实施例中的上行发送功率控制方法的流程,具体步骤如下:
步骤201、UE发送第一系统信息请求失败后,控制上行发送功率爬升计数器对系统信息请求的发送失败次数进行计数,得到第一计数值;
可选地,UE根据如下公式确定额外增加的上行发送功率:
额外增加的上行发送功率=第一计数值×上行发送功率爬升的每次增加的功率值。可选地,上行发送功率爬升的每次增加的功率值可以设置为2dB,当然也并不限于此。
上述第一计数值是由上行发送功率爬升计数器基于所述上行发送功率爬 升计数器中的第二计数值和预设的数值计算得到的;
其中,所述第二计数值是上行发送功率爬升计数器的初始值,或者是在发送第一系统信息请求之前,所述上行发送功率爬升计数器计数得到的计数值。
上述上行发送功率爬升计数器的初始值可以设置为1,当然并不限于此。
步骤202、UE根据第一计数值和预先配置的上行发送功率爬升的每次增加的功率值,确定额外增加的上行发送功率。
在本实施例中,可选地,所述方法还包括:UE判断所述上行发送功率爬升计数器中的计数值是否大于或等于上行发送功率爬升计数器的最大值;如果是,所述UE控制所述上行发送功率爬升计数器保持所述第二计数值不变;如果上行发送功率爬升计数器中的计数值小于上行发送功率爬升计数器的最大值,进入所述UE控制上行发送功率爬升计数器对所述第一系统信息请求的失败次数进行计数,得到第一计数值的步骤。可选地,上行发送功率爬升计数器的最大值可以设置为5,当然并不限于此。
在本实施例中,可选地,所述方法还包括:
如果所述UE系统信息请求发送失败的次数超过预定次数,或UE接入新的小区,或UE的小区禁止接入定时器超时,UE对所述上行发送功率爬升计数器进行复位处理。例如UE将所述上行发送功率爬升计数器重置为上行发送功率爬升计数器的初始值。
在本实施例中,以下至少一项由网络配置或者由协议约定:上行发送功率爬升计数器的初始值;以及上行发送功率爬升计数器的最大值。
在本实施例中,可以在UE发送系统信息请求失败后,通过提升系统信息请求的上行发送功率,提高系统信息请求的发送成功率。
参见图3,图中示出了本公开另一个实施例中的上行发送功率控制方法的流程,具体步骤如下:
步骤301、UE发送第一系统信息请求失败后,确定上行发送功率爬升的每次增加的功率值;
例如:上行发送功率爬升的每次增加的功率值可以设置为2dB,当然也并不限于此。
步骤302、UE根据发送第一系统信息请求的第一上行发送功率和上行发送功率爬升的每次增加的功率值,确定发送第二系统信息请求的第二上行发送功率。
在本实施例中,可选地,图3所示的方法还包括:UE判断发送第一系统信息请求的第一上行发送功率是否小于或等于预先配置的上行发送功率的最大值和/或UE判断上行发送功率爬升的每次增加的功率值的累加值是否小于或等于上行功率爬升的最大功率值;如果是,则执行图3中的步骤301,即执行UE确定额外增加的上行发送功率的步骤。可选地,上行发送功率的最大值为20dB,上行发送功率爬升的每次增加的功率值为2dB,上行功率爬升的最大功率值为10dB,当然也并不限于此。
在本实施例中,如果所述UE系统信息请求发送失败的次数超过预定次数,或如果所述UE接入新的小区,或如果所述UE的小区禁止接入定时器超时,所述UE对上行发送功率值进行复位处理,重置为初始值。
在本实施例中,以下至少一项由网络配置或者由协议约定:上行发送功率爬升的每次增加的功率值;上行发送功率爬升的最大功率值;以及上行发送功率的最大值。
在本公开的另一个实施例中,当UE判断某一次On-demand SI(On-demand System Information,按需系统信息)请求失败后,将上行发送功率爬升计数器的计数值增加预设值(例如该预设值为1),并在再次发送On-demand SI请求的时候额外增加上行发送功率,该额外增加的上行发送功率为(计数值×上行发送功率爬升的每次增加的功率值)。
当UE判断小区的On-demand SI请求失败后,UE将该上行发送功率爬升计数器的计数值重置为上行发送功率爬升计数器的初始值。
需要说明的是,On-demand SI请求对于每个小区都是独立的。如果UE请求On-demand SI请求1次失败,则仅仅是单次On-demand SI请求失败,UE可以再次发送On-demand SI请求。如果UE发送On-demand SI请求多次后依然失败,则是对于对应小区的On-demand SI请求失败,UE可能会选择新的小区,或认为该小区暂时(即启动禁止接入定时器)不能接入。
在本实施例中,用于On-demand SI请求的上行功率爬升计数器的初始值 和/或上行功率爬升计数器的最大值通过网络配置或协议约定。
参见图4,图中示出了本公开另一个实施例中的上行发送功率控制方法的流程,具体步骤如下:
步骤401:如果On-demand SI请求发送失败,UE判断上行发送功率爬升计数器的计数值是否大于或等于上行发送功率爬升计数器的最大值,若是,进入步骤404;否则,进入步骤402。
步骤402:UE将上行发送功率爬升计数器的计数值加1。
即,SI_REQ_COUNTER=SI_REQ_COUNTER+1,其中,SI_REQ_COUNTER表示上行发送功率爬升计数器的计数值。
上行功率爬升计数器的初始值和/或上行功率爬升计数器的最大值通过网络配置或协议约定。
例如,网络侧配置On-demand SI请求的上行功率相关信息,包括:
上行功率爬升计数器的初始值(如initialCounter=1);
上行功率爬升计数器的最大值(如maxCounter=5);
上行功率爬升的每次增加的功率值(如powerRampingStep=2dB)。
步骤403:UE在下一次发送On-demand SI请求的时候,额外增加的功率值为上行发送功率爬升计数器的计数值与上行发送功率爬升的每次增加的功率值的乘积。
即,额外增加的功率值等于SI_REQ_COUNTER×powerRampingStep。
步骤404:UE控制该上行发送功率爬升计数器的计数值不再增加。
UE每次判断On-demand SI请求信息发送失败,重复上述步骤301和302,直至该上行发送功率爬升计数器的计数值大于或等于上行发送功率爬升计数器的最大值,该上行发送功率爬升计数器的计数值不再增加。
在本实施例中,如果UE判断对于相应小区的On-demand SI请求信息发送失败,则UE需要对该上行发送功率爬升计数器复位,重置为初始值。
需要说明的是,上行发送功率爬升计数器配置可以是:按小区配置,或者是按照SI请求配置。
在本公开的另一个实施例中,当UE判断某一次On-demand SI请求失败后,UE在再次发送On-demand SI请求时根据配置在上一次On-demand SI请 求的发送功率基础上加上上行功率爬升的每次增加的功率值。
当UE判断在该小区的On-demand SI请求失败后,UE将On-demand SI请求的上行功率重置为初始值。
用于On-demand SI请求的上行功率爬升的每次增加的功率值、On-demand SI请求的上行功率爬升的最大功率值和/或上行发送功率的最大值通过网络配置或协议约定。
在本实施例中,可以在UE发送On-demand SI请求失败后,通过提升On-demand SI请求的上行发送功率,提高On-demand SI请求的发送成功率。
参见图5,图中示出了本公开另一个实施例中的上行发送功率控制方法的流程,具体步骤如下:
步骤501:UE发送On-demand SI请求后,UE判断该On-demand SI请求发送失败,UE判断发送On-demand SI请求的上行发送功率是否小于或等于上行发送功率的最大值,或UE判断上行发送功率爬升的每次增加的功率值的累加值是否小于或等于上行功率爬升的最大功率值,若是,执行步骤402和步骤403;否则结束流程。
步骤502:UE计算下次发送On-demand SI请求的上行发送功率为:上次发送On-demand SI请求的上行发送功率加上上行功率爬升的每次增加的功率值。
即,P(i+1)=P(i)+powerRampingStep,其中
P(i+1)表示下次发送On-demand SI请求的上行发送功率;
P(i)表示上次发送On-demand SI请求的上行发送功率;
可选地,网络侧配置On-demand SI请求的上行功率相关信息包括:
上行发送功率爬升的每次增加的功率值(如powerRampingStep=2dB)。
上行发送功率爬升的最大功率值(如maxPowerRampingStep=10dB)。
上行发送功率的最大值(如maxReqPower=20dBm)。
步骤503:UE在下一次发送On-demand SI请求的时候,按照下次发送On-demand SI请求的上行发送功率进行发送。
在本实施例中,如果UE判断对于相应小区的On-demand SI请求信息发送失败,则UE需要对上行发送功率值复位,重置为初始值。
基于同一发明构思,本公开实施例中还提供了一种终端,由于该终端解决问题的原理与本公开实施例上行发送功率控制方法相似,因此该基站的实施可以参见方法的实施,重复之处不再敷述。

继续参见图8,所述终端600还包括:

- 根据权利要求16所述的终端设备,其中,所述终端设备还包括:第一复位模块,用于如果UE的系统信息请求发送失败的次数超过预定次数,或如果所述UE接入新的小区,或如果UE的小区禁止接入定时器超时,对所述上行发送功率爬升计数器进行复位处理。
- 根据权利要求17所述的终端设备,其中,所述第一复位模块进一步用于将所述上行发送功率爬升计数器重置为所述上行发送功率爬升计数器的初始值。
- 根据权利要求12至19中任一项所述的终端设备,其中,所述额外增加的上行发送功率为:上行发送功率爬升的每次增加的功率值。
- 根据权利要求19所述的终端设备,其中,所述终端设备还包括:第二判断模块,用于判断发送所述第一系统信息请求的第一上行发送功率是否小于或等于预先配置的上行发送功率的最大值或判断上行发送功率爬升的每次增加的功率值的累加值是否小于或等于上行功率爬升的最大功率值;如果是,触发第一确定模块确定上行发送功率爬升的每次增加的功率值。
- 根据权利要求13至20中任一项所述的终端设备,其中,所述终端设备还包括:第二复位模块,用于如果UE发送系统信息请求的发送失败的次数超过预定次数,或如果UE接入新的小区,或如果UE的小区禁止接入定时器超时,对上行发送功率值进行复位处理。
- 根据权利要求13至21中任一项所述的终端设备,其中,以下至少一项由网络配置或者由协议约定:上行发送功率爬升计数器的初始值;上行发送功率爬升计数器的最大值;上行发送功率爬升的每次增加的功率值;上行发送功率爬升的最大功率值;以及上行发送功率的最大值。
- 一种终端设备,包括:处理器、存储器及存储在所述存储器上并可在所述处理器上运行的计算机程序,所述计算机程序被所述处理器执行时实现如权利要求1至11中任一项所述的上行发送功率控制方法中的步骤。
- 一种计算机可读存储介质,所述计算机可读存储介质上存储有计算机程序,所述计算机程序被处理器执行时实现如权利要求1至11中任一项所述的上行发送功率控制方法中的步骤。
