图 1为本发明实施例的异构网络架构示意图。 如图 1所示, 在异构网络 中, 包括宏基站和小基站。 其中, 宏基站 (未示出) 的信号覆盖区域为图
1中的深灰色 F1覆盖的区域, 小基站的信号覆盖区域为图 1中的深灰色 F2 覆盖的区域。 在图 1中, 立方体覆盖的小基站位于宏基站的信号覆盖漏洞 区域, 其它小基站位于宏基站的业务热点区域。 宏基站提供广覆盖, 负责 控制信令和用户数据业务的传输。 小基站为用户设备提供信号覆盖或业务 分流, 例如家庭基站 (Home evolved Node B , 简称 HeNB ) 、 微基站、 射 频拉远 (Radio remote head, 简称 RRH ) 等, 主要负责部分或全部的用户 数据业务的传输。宏基站和小基站可以通过载波聚合的技术同时承担用户 数据业务的传输, 同时, 用户设备需要分别与小基站和宏基站进行数据传 输。 在具体实现过程中, 存在保证宏基站的覆盖范围的激活载波, 以及保 证小基站的数据传输的激活载波, 在小基站和宏基站之间可以通过光纤连 接, 通过协作实现宏基站和小基站的载波聚合。 激活载波是指基站在使用 无线资源控制 (Radio Resource Control, 简称: RRC ) 信令为用户设备配 置载波之后再通过媒质接入控制 (Medium Access Control, 简称 MAC ) 控 制元素 (control element, 简称 CE) 指示用户设备激活该配置载波, 用户 设备在激活载波上才能进行数据传输。用户设备能够同时在两个或者两个 以上连续或者非连续的组成载波上发送上行数据和接收下行数据。本实施 例中的宏基站和小基站的载波聚合技术也可以被称为站点间的载波聚合 ( inter- site CA ),或双连接 ( dual-connection),又或多流聚合(multi-stream aggregation) 。
图 2为本发明用户设备实施例一的结构示意图。本实施例的用户设备 可以应用到图 1所示的异构网络中。 如图 2所示, 本发明实施例提供的用 户设备 20包括处理器 201和发射机 202。
其中, 处理器 201, 用于在用户设备与第一基站停止上行数据传输的情 况下, 如果所述用户设备再次与所述第一基站进行上行数据传输, 获取第一 基站的激活载波的功率余量和第二基站的激活载波的功率余量;
发射机 202, 用于向所述第一基站上报所述第一基站的激活载波的功率 余量和所述第二基站的激活载波的功率余量。
在本实施例中,所涉及的第一基站为宏基站,第二基站为小基站;或者, 第一基站为小基站, 第二基站为宏基站。
在具体实现过程中, 本实施例中的用户设备可以应用到图 1实施例中, 该用户设备可以分别与小基站和宏基站进行上行数据传输。 其中, 上行数 据传输为用户设备向宏基站 /小基站发送上行数据的过程。用户设备监听宏 基站 /小基站的物理下行控制信道 (Physical Downlink Control Channel, 简 称: PDCCH ) , 当用户设备检测到宏基站或小基站调度该用户设备, 并为 该用户设备分配上行资源等, 该用户设备根据调度信息在物理上行共享信 道(Physical Uplink Shared Channel, 简称: PUSCH )上向宏基站或小基站 发送上行数据。
当第一基站停止上行调度用户设备的情况下, 该用户设备与第一基站 停止上行数据传输, 在该用户设备和第一基站停止上行数据传输的期间 内, 第一基站无法获知用户设备的功率余量。 当用户设备再次与第一基站 进行上行数据传输时,用户设备的处理器 201获取第一基站的激活载波的功 率余量和第二基站的激活载波的功率余量, 并将第一基站的激活载波的功率 余量和第二基站的激活载波的功率余量上报给第一基站。
用户设备可以通过功率余量报告将其当前传输时刻第一基站的激活载波 的功率余量和第二基站的激活载波的功率余量 (即用户设备在其最大发射功 率范围内所有组成载波上所能发送的最大功率减去当前上行数据传输所消耗 的功率, 如果组成载波的上行数据传输已经超过了所述用户设备最大发射功 率, 则根据预设规则以所述用户设备最大发射功率为限来发送上行数据) 发 送给基站。 在本实施例中, 用户设备的处理器 201在用户设备再次与所述第 一基站进行上行数据传输时, 分别获取第一基站的激活载波的功率余量和第 二基站的激活载波的功率余量。 其中, 第一基站的激活载波的功率余量指用 户设备在第一基站的每一个激活载波上所能发送的最大功率减去当前用户设 备在第一基站的每一个激活载波的上行数据传输所消耗的实际功率, 第二基 站的激活载波的功率余量指用户设备在第二基站的每一个激活载波上所能发 送的最大功率减去用户设备在第二基站的每一个激活载波的上行数据传输所 消耗的实际功率。 第一基站有几个激活载波用户设备就会获得几个载波的功 率余量, 第二基站有几个激活载波用户设备就会获得几个载波的功率余量。 如果第一基站的激活载波和第二基站的激活载波实际需要的发射功率超过了 该用户设备的最大发射功率, 则根据预设规则以该用户设备的最大发射功率 为限进行上行数据的发送。
然后, 用户设备通过发射机 202向所述第一基站上报所述第一基站的激 活载波的功率余量和所述第二基站的激活载波的功率余量, 以使第一基站估 算用户设备的下行路损以及协调上行资源分配等,对该用户设备进行调度。
本发明实施例提供的用户设备, 应用于异构网络中, 所述异构网络包括 宏基站和小基站, 所述小基站部署在所述宏基站的覆盖漏洞区域或业务热点 区域, 所述宏基站和所述小基站通过载波聚合技术为用户设备提供服务, 包 括: 处理器, 用于在用户设备与第一基站停止上行数据传输的情况下, 如果 所述用户设备再次与所述第一基站进行上行数据传输, 获取第一基站的激活 载波的功率余量和第二基站的激活载波的功率余量; 发射机, 用于向所述第 一基站上报所述第一基站的激活载波的功率余量和所述第二基站的激活载波 的功率余量, 实现了在异构网络中, 当第一基站在一段时间没有调度用户设 备时, 该第一基站能够及时获知用户设备在激活载波上的功率余量, 从而根 据该功率余量对用户设备进行调度, 避免了第一基站对用户设备的过调度或 用户设备出现功率不足的问题。
下面采用几个具体的实施例, 对本发明可能的实现方式, 进行详细说明。 一种可能的实现方式, 在所述用户设备与所述第一基站停止上行数据传 输的情况下, 处理器 201启动定时器; 在所述用户设备再次与所述第一基站 进行上行数据传输的情况下, 如果所述定时器超时, 处理器 201获取所述第 一基站的激活载波的功率余量和所述第二基站的激活载波的功率余量, 发射 机 202向所述第一基站上报所述第一基站的激活载波的功率余量和所述第二 基站的激活载波的功率余量。
另一种可能的实现方式, 在所述用户设备再次与所述第一基站进行上行 数据传输的情况下, 如果所述用户设备在所述第一基站的服务下从连接态非 连续接收模式中的休眠态转为所述连接态非连续接收模式中的激活态, 处理 器 201获取所述第一基站的激活载波的功率余量和所述第二基站的激活载波 的功率余量。 发射机 202向所述第一基站上报所述第一基站的激活载波的功 率余量和所述第二基站的激活载波的功率余量。
具体地, 非连续接收 (Discontinuous Reception, 简称: DRX) 分两种: 空闲态非连续接收模式和连接态非连续接收模式, 连接态非连续接收模式还 包括激活态和休眠态。 其中, 连接态非连续接收模式允许用户设备在保持无 线资源控制连接的状态下周期性地在休眠态和激活态之间转换。 当用户设备 处于激活态时, 用户设备的接收天线开启, 以便用户设备接收下行数据, 用 户设备也可以在激活态时发送上行数据, 当用户设备处于休眠态时, 用户设 备的接收天线关闭, 用户设备不能接收下行数据, 同时也不能发送上行数据。 空闲态非连续接收模式也和连接态非连续接收模式一样, 分为激活态和休眠 态。
又一种可能的实现方式中, 所述处理器 201获取在所述用户设备与所述 第一基站停止上行数据传输前所述第二基站的激活载波的第一功率余量,和, 在所述用户设备与所述第一基站停止上行数据传输时到所述用户设备再次与 所述第一基站进行上行数据传输时的期间所述第二基站的激活载波的第二功 率余量; 如果所述第二功率余量相比所述第一功率余量的变化量超过了预设 门限, 处理器 201获取在所述用户设备再次与所述第一基站进行上行数据传 输时所述第一基站的激活载波的第二功率余量和所述第二基站的激活载波的 第三功率余量, 所述发射机 202向所述第一基站上报所述第一基站的激活载 波的第二功率余量和所述第二基站的激活载波的第三功率余量。
在具体实现过程中, 用户设备在第一基站的激活载波和第二基站的激活 载波的总功率不变, 因此, 第二基站的激活载波的功率余量的变化, 反应了 第一基站的激活载波的功率余量的变化, 当第二基站的激活载波的功率余量 变化不大时, 说明第一基站的激活载波的功率余量的变化不大。 以具体的时 间轴为例, 对本实施例进行详细说明。 图 3为本发明实施例功率余量上报时 间轴示意图一,由图 3所示,在时间轴 t上,以传输时间间隔(Transmission Time Interval,简称 ΤΉ)为单位,包括 ΤΉ1 (tl-t2)、 TTI2 (t2-t3 ) 、 TTI3 (t3-t4) 。 其中, 在 ΤΉ1和 ΤΉ3上为用户设备向第一基站发送上行数据的时间。 具体 地, 处理器 201获取在所述用户设备与所述第一基站停止上行数据传输前所 述第二基站的激活载波的第一功率余量 PH1 , 即在 t2时间之前, 获取 PH1 ; 处理器 201获取在用户设备与第一基站停止上行数据传输时到用户设备再次 与第一基站进行上行数据传输时的期间第二基站的激活载波的第二功率余量 PH2, 即在 t2至 t3期间, 获取 PH2。
如果第二功率余量 PH2相比第一功率余量 PH1 的变化量超过了预设门 限, 说明第一基站的激活载波的功率余量变化较大。 其中, 变化量具体可以 为 PH2与 PH1相除得到的商或者相减得到的差, 或者其它衡量变化, 本实施 例此处不做特别限制。 预设门限可以为根据经验值确定的门限, 当超过该门 限, 说明第一基站的功率余量变化较大, 将影响第一基站调度用户设备。 处 理器 201获取在用户设备再次与第一基站进行上行数据传输时第一基站的激 活载波的第二功率余量和第二基站的激活载波的第三功率余量,即处理器 201 获取在 t3时间点的第一基站的激活载波的第二功率余量和第二基站的激活载 波的第三功率余量。 发射机 202向所述第一基站上报所述第一基站的激活载 波的第二功率余量和所述第二基站的激活载波的第三功率余量。 在上述实施例的基础上,可选地,再加上定时器超时的条件。具体地, 在 所述用户设备与所述第一基站停止上行数据传输前, 处理器 201获取所述第 二基站的激活载波的第一功率余量, 处理器 201启动定时器, 如果所述定时 器超时, 处理器 201获取所述第二基站的激活载波的第二功率余量。
具体地, 处理器 201获取所述第二基站的激活载波的第一功率余量与上 述实施例类似, 本实施例此处不再赘述。 本实施例与上述实施例不同之处在 于, 处理器 201获取在所述用户设备与所述第一基站停止上行数据传输时到 所述用户设备再次与所述第一基站进行上行数据传输时的期间所述第二基站 的激活载波的第二功率余量时, 还需要考虑定时器的因素。 即处理器 201获 取第二基站的激活载波的第一功率余量之后, 在定时器超时后, 即定时器停 止运行后, 获取在用户设备与第一基站停止上行数据传输时到用户设备再次 与第一基站进行上行数据传输时的期间第二基站的激活载波的第二功率余 需要说明的是,预设门限和定时器都是第一基站通过 RRC信令配置给用 户设备的。
可选地, 所述用户设备还包括: 接收机, 用于在处理器获取第一基站的 激活载波的功率余量和第二基站的激活载波的功率余量之前, 接收所述第一 基站通过无线资源控制信令发送的定时器对应的定时器信息和预设门限对应 的预设门限信息。
下面采用具体的实施例, 对上述实施例中用户设备获取在所述用户设备 与所述第一基站停止上行数据传输前所述第二基站的激活载波的第一功率余 量进行说明。 具体可分为以下情况:
一种情况 A, 处理器 201获取在用户设备与第一基站停止上行数据传输 前,最后一次向第二基站发送的或最后一次与第二基站进行上行数据传输时, 第二基站的激活载波的第一功率余量。
具体地, 请继续参照图 3, 处理器 201获取在用户设备与第一基站停止 上行数据传输前, 即 tl时间之前, 用户设备最后一次向第二基站发送的或最 后一次与第二基站进行上行数据传输时, 第二基站的激活载波的第一功率余 另一种情况 B, 处理器 201获取在用户设备与第一基站停止上行数据传 输前, 最后一次向第一基站发送的或最后一次与第一基站进行上行数据传输 时, 第二基站的激活载波的第一功率余量。
具体地, 请继续参照图 3, 处理器 201获取在用户设备与第一基站停止 上行数据传输前, 即 tl时间之前, 用户设备最后一次向第一基站发送的或最 后一次与第一基站进行上行数据传输时, 第二基站的激活载波的第一功率余 下面再采用具体的实施例, 对上述实施例中用户设备获取在用户设备与 第一基站停止上行数据传输时到用户设备再次与第一基站进行上行数据传输 时的期间第二基站的激活载波的第二功率余量进行说明。 本领域技术人员可 以理解, 在具体实现过程中, 可以包括定时器条件, 也可以不包括定时器条 件, 本实施例此处不再赘述。 具体可分为以下情况:
一种情况 C, 处理器 201获取所述期间中任意一次或最后一次向所述第 二基站发送的, 所述第二基站的激活载波的第二功率余量。
