图 1为本发明实施例一所提供的上行功率控制方法的流程图。 本实施例 的方法适用于对小区覆盖范围内的 UE进行上行功率控制的情况。 该方法由 上行功率控制装置执行, 该装置通常以硬件和 /或软件的方式来实现。 本实施 例的方法包括如下步骤:
110、基站根据第一接入次数和第二接入次数, 确定是否对小区级上行功 率参数进行调整, 其中, 第一接入次数为基站的小区覆盖范围内的用户设备 UE发送一次随机接入前导接入小区的次数,第二接入次数为小区覆盖范围内 的 UE发送至少两次随机接入前导接入小区的次数。
由于现有技术中进行上行功率控制依赖大量的测量数据, 因此会消耗较 多的测量资源。而 110中的第一接入次数和第二接入次数是小区覆盖范围内的 UE接入小区后基站就能根据 UE上报的 UE接入小区前发送的随机接入前导的次 数统计出来, 因此基站不需要不断的测量 UE发送的上行信号的功率, 从而节 约了测量资源。 本实施例 110中基站根据根据第一接入次数和第二接入次数, 确定是否对小区级上行功率参数进行调整, 从而确定是否进入 120。
120、若确定对小区级上行功率参数进行调整, 则基站调整小区级上行功 率参数, 并将调整后的小区级上行功率参数发送给小区覆盖范围内的 UE, 以 使小区覆盖范围内的 UE根据调整后的小区级上行功率参数发送上行信号。
具体的, 基站根据根据第一接入次数和第二接入次数确定是否对小区级 上行功率参数进行调整, 若确定对小区级上行功率参数进行调整, 则调整小 区级上行功率参数, 并将调整后的小区级上行功率参数发送给小区覆盖范围 内的 UE, 以使小区覆盖范围内的 UE根据调整后的小区级上行功率参数发送 上行信号。
本实施例提供的上行功率控制方法, 通过根据第一接入次数和第二接入 次数, 确定是否对小区级上行功率参数进行调整, 若确定对小区级上行功率 参数进行调整, 则调整小区级上行功率参数, 并将调整后的小区级上行功率 参数发送给小区覆盖范围内的 UE, 以使小区覆盖范围内的 UE根据调整后的 小区级上行功率参数发送上行信号。 从而解决了现有技术中因不断测量 UE 的发射信号的功率来调整小区级上行功率参数造成资源浪费的问题, 节约了 测量资源。
图 2为本发明实施例二所提供的上行功率控制方法的流程图。 参照图 2, 本实施例的方法可以包括:
210、基站根据第一接入次数和第二接入次数的比值, 确定是否对小区级 上行功率参数进行调整。
举例来说, 根据第一接入次数和第二接入次数的比值, 确定是否对小区 级上行功率参数进行调整可以通过如下方式实现:
a 基站根据第一接入次数 a和第二接入次数 b计算比值 χ, 其中, Χ=^, 若比值 X大于等于预设的第一门限值, 则确定对小区级上行功率参数进行调 整。 如果 X的值较大, 说明小区覆盖范围内大多数 UE都是发送了一次随机 接入前导接入小区的, 可以确定小区级上行功率参数设置较大, 也即可以根 据该比值 X的大小确定小区级上行功率参数的大小, 从而确定是否对小区级 上行功率参数进行调整。
220、若确定对小区级上行功率参数进行调整, 则基站调整小区级上行功 率参数, 并将调整后的小区级上行功率参数发送给小区覆盖范围内的 UE, 以 使小区覆盖范围内的 UE根据调整后的小区级上行功率参数发送上行信号。
举例来说, 调整小区级上行功率参数可以通过如下方式实现:
例如比值 X大于等于预设的第一门限值时, 减小小区级上行功率参数的 取值从而实现对小区级上行功率参数进行调整。 其中, 减小小区级上行功率 参数的取值可以通过采用预设的第一调整步长来减小小区级上行功率参数的 取值。
需要说明的是, 如果确定小区级上行功率参数设置较大, 可以采用预设 的第一调整步长来减小小区级上行功率参数的取值, 其中, 第一调整步长可 以根据不同信道的解调性能和干扰的大小来设置, 例如设置第一调整步长为 ldbm或 2dbm。通过调整小区级上行功率参数的取值降低小区间干扰。例如, 当比值 X大于等于预设的第一门限值, 设置第一门限值为 90%, 则减小小区 级上行功率参数的取值, 如果当前小区级上行功率参数例如 pO-NominalPUCCH的值是 -105dbm, 设置的第一调整步长为 2dbm, 那么调整 后的 pO-NominalPUCCH的值为 -107dbm。
本实施例提供的上行功率控制方法, 通过根据第一接入次数和第二接入 次数的比值, 确定是否对小区级上行功率参数进行调整, 当比值大于等于预 设的第一门限值时, 通过减小小区级上行功率参数的取值对小区级上行功率 参数进行调整, 从而解决了现有技术中因不断测量 UE 的发射信号的功率来 调整小区级上行功率参数造成资源浪费的问题, 节约了测量资源。
参见图 2, 本实施例提供的上行功率控制方法的流程图与图 2相同。 在 本实施例中, 根据第一接入次数和第二接入次数的比值, 确定是否对小区级 上行功率参数进行调整可以通过如下方式实现:
_ b 基站根据第一接入次数 a和第二接入次数 b计算比值 y, 其中, y=^, 若比值 y大于等于预设的第二门限值, 则确定对小区级上行功率参数进行调 整。 在本实施中, 如果比值 y的值较大, 说明小区覆盖范围内大多数 UE都是 发送了至少两次随机接入前导接入小区的, 可以确定小区级上行功率参数设 置较小, 也即可以根据该比值 y的大小确定小区级上行功率参数的大小, 从 而确定是否对小区级上行功率参数进行调整。
本实施中, 若确定对小区级上行功率参数进行调整, 则基站调整小区级 上行功率参数, 并将调整后的小区级上行功率参数发送给小区覆盖范围内的 UE, 以使小区覆盖范围内的 UE根据调整后的小区级上行功率参数发送上行 信号。 其中, 调整小区级上行功率参数可以通过如下方式实现:
例如比值 y大于等于预设的第二门限值时, 基站增大小区级上行功率参 数的取值从而实现对小区级上行功率参数进行调整。 其中, 基站增大小区级 上行功率参数的取值可以为基站采用预设的第二调整步长来增大小区级上行 功率参数的取值。
需要说明的是, 如果确定小区级上行功率参数设置较小, 可以采用预设 的第二调整步长来增大小区级上行功率参数的取值, 其中, 第二调整步长可 以根据不同信道的解调性能和干扰的大小来设置, 例如设置第二调整步长为 ldbm或 2dbm。 通过增大小区级上行功率参数的取值提升 UE的上行解调性 會^ 例如, 当比值 y大于预设的第二门限值, 例如第二门限值为 40%, 则增 大小区级上行功率参数的取值, 如果当前小区级上行功率参数例如 "pO-NominalPUCCH"的值是 -105dbm, 设置的第二调整步长为 ldbm, 那么 调整后的 "pO-NominalPUCCH" 的值为 -104dbm。
本实施例提供的上行功率控制方法, 通过基站根据第一接入次数和第二 接入次数的比值, 确定是否对小区级上行功率参数进行调整, 当比值大于等 于预设的第二门限值时, 增大小区级上行功率参数的取值对小区级上行功率 参数进行调整, 从而解决了现有技术中因不断测量 UE 的发射信号的功率来 调整小区级上行功率参数造成资源浪费的问题, 节约了测量资源。
图 3为本发明实施例三所提供的上行功率控制方法的流程图。 本实施例 的方法包括如下步骤:
310、 小区覆盖范围内的用户设备 UE接收基站发送的小区级上行功率参 数, 其中, 小区级上行功率参数为基站根据第一接入次数和第二接入次数确 定是否对小区级上行功率参数进行调整, 并在确定对小区级上行功率参数进 行调整时调整小区级上行功率参数并向小区覆盖范围内的 UE发送的, 第一 接入次数为小区覆盖范围内的 UE发送一次随机接入前导接入小区的次数, 第二接入次数为小区覆盖范围内的 UE发送至少两次随机接入前导接入小区 的次数。
320、 UE根据接收的调整后的小区级上行功率参数发送上行信号。
UE根据接收的调整后的小区级上行功率参数的取值发送上行信号可以 通过如下方式实现: UE以接收的调整后的小区级上行功率参数的取值作为发 送上行信号的功率, 并以该功率发送上行信号。
本实施例提供的上行功率控制方法, 通过 UE接收基站发送的调整后的 小区级上行功率参数, 并根据接收的调整后的小区级上行功率参数发送上行 信号。 从而解决了现有技术中因不断测量 UE的发射信号的功率来调整小区 级上行功率参数造成资源浪费的问题, 节约了测量资源。
图 4为本发明实施例四所提供的上行功率控制方法的流程图。 本实施例 的方法包括如下步骤:
410、 基站根据第一功率和用户设备 UE接入小区前发送随机接入前导的 总次数, 确定是否对 UE级上行功率参数进行调整, 其中, 第一功率为 UE 接入基站的小区前发送第一次随机接入前导的功率。
由于第一功率和 UE接入小区前发送随机接入前导的总次数为 UE接入小 区后就会上报给基站的数据, 因此基站不需要等待 UE上报信干噪比, 而是 根据第一功率和用户设备 UE接入小区前发送随机接入前导的总次数来确定 是否对 UE级上行功率参数进行调整, 因此节约了测量资源, 而且实现了在 UE接入小区后就能够对上行功率参数进行调整, 因此更能够对 UE级上行功 率参数进行实时调节。
420、 若确定对 UE级上行功率参数进行调整, 则基站调整 UE级上行功 率参数, 并将调整后的 UE级上行功率参数发送给 UE, 以使 UE根据调整后 的 UE级上行功率参数发送上行信号。
具体的, 基站根据第一功率和用户设备 UE接入小区前发送随机接入前 导的总次数,确定是否对 UE级上行功率参数进行调整,若确定对 UE级上行 功率参数进行调整,则基站调整 UE级上行功率参数,并将调整后的 UE级上 行功率参数发送给 UE, 以使 UE根据调整后的 UE级上行功率参数发送上行 信号。
本实施例提供的上行功率控制方法, 通过基站根据第一功率和用户设备
UE接入小区前发送随机接入前导的总次数, 确定是否对 UE级上行功率参数 进行调整,若确定对 UE级上行功率参数进行调整,则基站调整 UE级上行功 率参数, 并将调整后的 UE级上行功率参数发送给 UE, 以使 UE根据调整后 的 UE级上行功率参数发送上行信号。从而解决了现有技术中因不断测量 UE 的发射信号的功率来调整小区级上行功率参数造成资源浪费的问题, 节约了 测量资源, 并且能够实现对 UE级上行功率参数进行实时调节。
图 5为本发明实施例五所提供的上行功率控制方法的流程图。 本实施例 的方法包括如下步骤:
510、 基站根据第一功率 P。和 UE接入小区前发送随机接入前导的总次数 n计算第二功率 P 其中, P^Po + ^ xS , S为预设的调整步长, 第二功率 为
UE接入小区前最后一次发送随机接入前导的功率。
由于 LTE协议 36.331的 Release 9版本中引入了 UE信息请求消息和 UE 信息响应消息, 在 UE的无线资源控制连接建立成功后, eNodeB发送 UE信 息请求消息向 UE请求上报随机接入过程信息, UE在 UE信息响应消息中反 馈最近一次成功接入小区前总共发送的随机接入前导的次数。 本实施中为了 解决现有技术中依赖测量数据进行上行功率控制造成测量资源浪费的问题, 本实施例中通过发送的前导次数和发送第一次随机接入前导的功率来估算出 UE合适的上行发射功率, 进一步确定是否对 UE级上行功率参数进行调整, 从而实现了不依赖测量数据, 因此节约了测量资源。
520、 基站根据第二功率 ρι, 确定是否对 UE级上行功率参数进行调整。 若第二功率 Pl与小区级上行功率参数 P∞u不相等, 则基站确定对 UE级上 行功率参数进行调整。
530、 若确定对 UE级上行功率参数进行调整, 则基站调整 UE级上行功 率参数, 并将调整后的 UE级上行功率参数发送给 UE, 以使 UE根据调整后 的 UE级上行功率参数发送上行信号。
举例来说, 基站调整 UE级上行功率参数可以通过如下方式实现: 基站 调整 UE级上行功率参数的取值 为 , P = P, - Pcell
针对 510~530,在此配合一实例进行说明,例如,第一功率^3。为- 104dbm, 如果某个 UE是发送三次随机接入前导才成功接入小区的, 且设置的随机接 入前导功率攀升步长即预设的调整步长是 2dbm, 那 UE第二次发送随机接入 前导时的功率是 -102dbm, 第三次发送随机接入前导时的功率是 -lOOdbm, 因 此, UE是以 -104+2 X (3-1 ) =-100dbm的功率接入到小区的, 相应的可以调 整 UE级功率控制参数例如 "pO-UE-PUCCH" , "pO-UE-PUSCH" 。 由于调 整" pO-UE-PUCCH", "pO-UE-PUSCH"的方法相同,在此仅以" pO-UE-PUCCH" 为例进行介绍, 假设当前的小区级上行功率参数 "pO-NominalPUCCH" 的取 值是 -105dbm, 而根据 UE发送随机接入前导的次数和第一功率73。确定的当前 UE比较合适的功率是 -lOOdbm, 那么需要将 UE级功率参数 "pO-UE-PUCCH "调整为 (-100) - (-105 ) =5来适应当前的物理上行控制信道的功率, 不用 等 UE上报信干噪比就可以对 UE级功率参数进行调整,并将调整后的 UE级 功率参数 "pO-UE-PUCCH"通过无线资源控制重配消息下发给 UE。
本实施例提供的上行功率控制方法, 通过基站根据第一功率73。和 UE接 入小区前发送随机接入前导的总次数 n计算第二功率 基站根据第二功率 , 确定是否对 UE级上行功率参数进行调整。若确定对 UE级上行功率参数进行 调整,基站调整 UE级上行功率参数,并将调整后的 UE级上行功率参数发送 给 UE, 以使 UE根据调整后的 UE级上行功率参数发送上行信号。 从而解决 了现有技术中因不断测量 UE的发射信号的功率来调整小区级上行功率参数 造成资源浪费的问题, 节约了测量资源, 并且能够实现对 UE级上行功率参 数进行实时调节。
图 6为本发明实施例六所提供的上行功率控制方法的流程图。 本实施例 的方法包括如下步骤:
610、 用户设备 UE接收基站发送的 UE级上行功率参数, 其中, UE级 上行功率参数为基站根据第一功率和 UE接入基站的小区前发送随机接入前 导的总次数确定是否对 UE级功率参数进行调整,并在确定对 UE级上行功率 参数进行调整时调整 UE级上行功率参数并向 UE发送的,第一功率为 UE接 入小区前发送第一次随机接入前导的功率。
620、 UE根据接收的调整后的 UE级上行功率参数发送上行信号。
UE根据接收的调整后的 UE级上行功率参数的取值发送上行信号可以通 过如下方式实现: UE以接收的调整后的 UE级上行功率参数的取值与接收的 小区级上行功率参数的取值之和作为发送上行信号的功率, 并以该功率发送 上行信号。
需要说明是是,由于小区级上行功率参数是通过 2类系统信息块(System Information Block, 简称 SIB ) 发送给 UE的, 因此, UE在接收到 SIB2发送 的小区级上行功率参数后, 可以以接收的调整后的 UE级上行功率参数与接 收的小区级上行功率参数之和作为发送上行信号的目标功率, 并以该功率发 送上行信号。
本实施例提供的上行功率控制方法, 通过 UE接收基站发送的调整后的 UE级上行功率参数,并根据接收的调整后的小区级上行功率参数发送上行信 号。 从而解决了现有技术中 UE接收基站根据测量结果来调整小区级上行功 率参数从而造成资源浪费的问题, 节约了测量资源。
图 7为本发明实施例七所提供的上行功率控制装置 700的结构示意图。 本实施例的装置适用于对小区覆盖范围内的 UE进行上行功率控制的情况。 该装置通常以硬件和 /或软件的方式来实现。参照图 7, 该装置包括如下模块: 功率参数调整确定模块 710和功率参数调整模块 720。
功率参数调整确定模块 710用于根据第一接入次数和第二接入次数, 确 定是否对小区级上行功率参数进行调整, 其中, 第一接入次数为基站的小区 覆盖范围内的用户设备 UE发送一次随机接入前导接入小区的次数, 第二接 入次数为小区覆盖范围内的 UE发送至少两次随机接入前导接入小区的次数; 功率参数调整模块 720用于若确定对小区级上行功率参数进行调整, 则调整 小区级上行功率参数, 并将调整后的小区级上行功率参数发送给小区覆盖范 围内的 UE, 以使小区覆盖范围内的 UE根据调整后的小区级上行功率参数发 送上行信号。
