需要说明的是, 所述 UE由所述第一基站和所述第二基站控制, 所述 UE的 控制面连接维持在第一基站下, 所述 UE的用户面传输保持在第二基站下, 所 述第一基站可以为宏基站 Macro eNB,所述第二基站可以为所述第一基站下的 辅基站。
现有小小区部署场景中, 用户设备 UE需要同时监听宏基站(第一基站) 和微基站 (第二基站) 的 PDCCH上的数据传输, 不能做到合理的省电。 与现 有技术相比, 本发明实施例中令用户设备 UE在大部分时间只监听第一基站的 PDCCH; 当第二基站与 UE有数据传输时, 第一基站向 UE发送监听指示信息, 指示 UE监听第二基站的 PDCCH; 当 UE与第二基站之间的数据传输完毕后, 第二基站通知第一基站, 第一基站向 UE发送监听中止信息, 指示 UE停止监听 第二基站的 PDCCH。 从而使 UE能够在多数时间内只对第一基站的 PDCCH进 行监听, 相比于一直监听两个基站的 PDCCH, 降低了 UE的电量消耗。 本发明另一实施例提供一种省电方法, 如图 3所示, 所述方法包括: 301、 微基站向宏基站发送传输请求消息。
需要说明的是, 在本实施例的实施场景中, 宏基站和微基站均对同一个 UE进行控制, 本实施例中仅是以宏基站下接入一个微基站的情形为例。 可选 的, 本实施例中的方法对宏基站接入多个微基站的情形同样适用。 例如, 宏 基站下可以接入多个微基站, 业务数据通过宏基站发送给微基站, 再由微基 站发送给 UE。 其中, UE总是优先监听宏基站的 PDCCH上的数据传输, 当微 基站有数据达到时, 微基站向宏基站发送传输请求消息, 然后宏基站通知 UE 对微基站进行监听。即通过宏基站对微基站以及 UE的调度交互实现 UE对微基 站的非连续接收。
302、 宏基站根据传输请求消息向 UE发送监听指示信息。
其中,所述监听指示信息用于指示所述 UE去监听微基站的 PDCCH上的数 据传输。 例如, 所述监听指示信息可以包括: 第一监听指示信息, 所述第一 监听指示信息用于指示所述 UE立即监听所述微基站的 PDCCH, 即 UE在接收 到第一监听指示信息后立即监听微基站的 PDCCH; 或者, 第二监听指示信息, 所述第二监听指示信息用于指示所述 UE在间隔设定时间之后监听所述微基站 的 PDCCH, 即 UE在接收到第二监听指示信息后, 先等待一段时间再去监听微 基站的 PDCCH; 或者, 第三监听指示信息, 所述第三监听指示信息用于指示 所述 UE转向监听所述微基站的 PDCCH的起始时间, 即第三监听指示信息中包 含一个时间点, 指定 UE在这个时间点监听微基站的 PDCCH, 所述起始时间通 过 SFN ( System Frame Number, 系统帧号 )和子帧 sub frame表示, 例如, 所 述起始时间以 SFN+sub frame的形式表示。
其中, 所述监听指示信息可以携带在无线资源控制 RRC消息、 媒体访问 控制 MAC消息、 物理层消息或物理层消息信号中发送。
303、 宏基站接收 UE反馈的确认消息。
其中,所述确认消息在 UE正确接收到宏基站发送的监听指示信息后发送。
304、 宏基站向微基站发送传输允许消息。
可选的, 所述传输允许消息中可以携带微基站进行数据调度的起始时刻, 当微基站收到传输允许消息后, 在指定的时刻与 UE进行数据传输。
305、 UE根据监听指示信息对微基站的 PDCCH进行监听, 与微基站进行 数据传输。
需要说明的是, UE在步骤 302中接收到监听指示信息后, 即可执行步骤 305, 无须等到步骤 303和步骤 304执行之后。
306、 当在设定时间内没有需要传输的数据时,微基站向 UE发送监听中止 信息。
例如, 在 UE初始接入微基站时, 微基站可以设定一个特定时间长度。 微 基站与 UE进行数据传输过程中,如果微基站检测到与 UE之间没有数据传输的 时间长度大于等于设定的特定时间长度时, 则向 UE发送监听中止信息。
其中, 在设定时间段内无业务数据传输可以是数据已经传输完毕, 或者 数据传输故障。
可选的, 所述监听中止信息携带在无线资源控制 RRC消息、 媒体访问控 制 MAC消息、 物理层消息或物理层信号中发送。
可选的, 当在设定时间内没有需要传输的数据时, 微基站也可以向宏基 站发送数据传输消息, 通知宏基站当前的数据传输状态, 由宏基站根据网络 负荷或网络需求确定是否需要使所述 UE停止监听微基站; 当需要 UE停止监听 微基站时, 宏基站向 UE发送监听中止信息。
307、 UE停止监听微基站的 PDCCH上的数据传输。
可选的, 如果发送给 UE的监听中止信息是由宏基站发送的, 在 UE停止对 微基站的 PDCCH进行监听之后, 宏基站还需要向微基站发送指示消息, 通知 微基站 UE已经停止监听微基站的 PDCCH。 此步骤的目的在于: 使微基站知道 UE当前是否监听自己的 PDCCH的数据传输, 如果微基站不知道 UE已经停止 监听自己的 PDCCH的数据传输, 那么, 当微基站再有数据到达时, 微基站会 直接向 UE发送数据, 而此时 UE是不会接收该数据的, 会出现数据发送错误。
可选的, 当 UE停止监听微基站之后, 还可以周期性地向微基站发送 SRS 并获取微基站反馈的 TA, 通过上述步骤维护与微基站之间的上行同步。
需要说明的是,本发明实施例描述的省电方法对多载波下的 UE同样适用, 即 UE可以同时接入一个宏基站和多个微基站, 通过本实施例中的方法在多个 基站之间对 UE进行调度, 实现 UE省电。 现有小小区部署场景中, 用户设备 UE需要同时监听宏基站和微基站的 PDCCH上的数据传输, 不能做到合理的省电。 与现有技术相比, 本发明实施 例中令用户设备 UE在大部分时间只监听宏基站的 PDCCH; 当微基站与 UE有 数据传输时, 微基站向宏基站发送传输请求消息; 宏基站在接收到传输请求 消息后向 UE发送监听指示信息; UE根据监听指示信息监听微基站的 PDCCH; 当 UE与微基站之间的数据传输完毕后, UE接收微基站发送的监听中止信息, 停止监听微基站的 PDCCH。 从而使 UE能够在多数时间内只对宏基站的 PDCCH进行监听, 相比于一直监听两个基站的 PDCCH, 降低了 UE的电量消 耗。 本发明另一实施例提供一种省电方法, 如图 4所示, 所述方法包括: 401、当宏基站检测到微基站有业务数据到达时,向 UE发送监听指示信息。 需要说明的是, 在本实施例的实施场景中, 宏基站和微基站均对同一个 UE进行控制, 本实施例中仅是以宏基站下接入一个微基站的情形为例。 可选 的, 本实施例中的方法对宏基站接入多个微基站的情形同样适用。 例如, 宏 基站下可以接入多个微基站, 业务数据通过宏基站发送给微基站, 再由微基 站发送给 UE。 其中, UE总是优先监听宏基站的 PDCCH上的数据传输, 当微 基站有数据达到时, 微基站向宏基站发送传输请求消息, 然后宏基站通知 UE 对微基站进行监听。 即通过宏基站对微基站以及 UE的调度交互实现 UE对微基 站的非连续接收。
其中, 所述监听指示信息用于指示所述 UE监听微基站的物理下行控制信 道 PDCCH。 例如, 所述监听指示信息包括: 第一监听指示信息, 所述第一监 听指示信息用于指示所述 UE立即监听所述微基站的 PDCCH, 即 UE在接收到 第一监听指示信息后立即监听微基站的 PDCCH; 或者, 第二监听指示信息, 所述第二监听指示信息用于指示所述 UE在间隔设定时间之后监听所述微基站 的 PDCCH, 即 UE在接收到第二监听指示信息后, 先等待一段时间再去监听微 基站的 PDCCH; 或者, 第三监听指示信息, 所述第三监听指示信息用于指示 所述 UE转向监听所述微基站的 PDCCH的起始时间, 即第三监听指示信息中包 含一个时间点, 指定 UE在这个时间点监听微基站的 PDCCH, 所述起始时间通 过 SFN ( System Frame Number, 系统帧号 )和子帧 sub frame表示, 例如, 所 述起始时间以 SFN+sub frame的形式表示。
其中, 所述监听指示信息可以携带在无线资源控制 RRC消息、 媒体访问 控制 MAC消息、 物理层消息或物理层信号中发送。
402、 宏基站接收 UE反馈的确认消息。
其中,所述确认消息在 UE正确接收到宏基站发送的监听指示信息后发送。
403、 宏基站向微基站发送传输允许消息。
可选的, 所述传输允许消息中可以携带微基站进行数据调度的起始时刻, 当微基站收到传输允许消息后, 在指定的时刻与 UE进行数据传输。 例如, 所 述指定的时刻可以为: 在接收到传输允许消息后立即进行数据调度; 或者, 在接收到传输允许消息后, 根据传输允许消息中携带的信息等待一段时间间 隔后进行数据调度; 或者, 在接收到传输允许消息后, 根据传输允许消息中 携带的信息在特定的时间点去进行数据调度, 该时间点可以通过 SFN ( System Frame Number , 系统帧号) 和子帧 sub frame表示, 例如, 所述起始时间以 SFN+sub frame的形式表示。
404、 UE根据监听指示信息对微基站的 PDCCH进行监听, 与微基站进行 数据传输。
例如, 需要说明的是, UE在步骤 401中接收到监听指示信息后, 即可执行 步骤 404, 无须等到步骤 402和步骤 403执行之后。
405、 当在设定时间内没有需要传输的数据时,微基站向 UE发送监听中止 信息。
其中, 在设定时间段内无业务数据传输可以是数据已经传输完毕, 或者 数据传输故障。 可选的, 所述监听中止信息携带在无线资源控制 RRC消息、 媒体访问控 制 MAC消息、 物理层消息或物理层信号中发送。
可选的, 当在设定时间内没有需要传输的数据时, 微基站也可以向宏基 站发送数据传输消息, 通知宏基站当前的数据传输状态, 由宏基站根据网络 负荷或网络需求确定是否需要使所述 UE停止监听微基站; 当需要 UE停止监听 微基站时, 宏基站向 UE发送监听中止信息。
406、 UE停止监听微基站的 PDCCH上的数据传输。
可选的, 当 UE停止监听微基站之后, 还可以周期性地向微基站发送 SRS 并获取微基站反馈的 TA, 通过上述步骤维护与微基站之间的上行同步。
407、微基站向宏基站发送通知消息,通知宏基站 UE已经停止监听微基站 的 PDCCH。
需要说明的是, 此步骤的目的是为了使宏基站知道 UE已经不再监听微基 站的数据传输, 从而当微基站再有数据到达时, 宏基站会重新执行步骤 401。 避免出现微基站有数据到达时, 宏基站直接将数据发送给微基站, 而微基站 无法将该数据发送给 UE的情况。
需要说明的是,本发明实施例描述的省电方法对多载波下的 UE同样适用, 即 UE可以同时接入一个宏基站和多个微基站, 通过本实施例中的方法在多个 基站之间对 UE进行调度, 实现 UE省电。
现有小小区部署场景中, 用户设备 UE需要同时监听宏基站和微基站的 PDCCH上的数据传输, 不能做到合理的省电。 与现有技术相比, 本发明实施 例中令用户设备 UE在大部分时间只监听宏基站的 PDCCH; 当微基站与 UE有 数据传输时, 宏基站向 UE发送监听指示信息; UE根据监听指示信息监听微基 站的 PDCCH; 当 UE与微基站之间的数据传输完毕后, UE接收微基站发送的 监听中止信息, 停止监听微基站的 PDCCH; 微基站通知宏基站 UE已经不再监 听微基站的 PDCCH。 从而使 UE能够在多数时间内只对宏基站的 PDCCH进行 监听, 相比于一直监听两个基站的 PDCCH, 降低了 UE的电量消耗。 本发明另一实施例提供一种用户设备 UE50,如图 5所示,所述用户设备 50 包括:

当确定停止所述 UE监听所述第二基站的 PDCCH上的数据传输时,向所述 UE发送监听中止信息。
其中, 所述接收器 82接收的监听指示信息和所述接收器 82接收的监听中 止信息携带在无线资源控制 RRC消息、 媒体访问控制 MAC消息或物理层消息 或信号中发送。
其中, 所述接收器 82接收的监听指示信息包括: 第一监听指示信息, 所 述第一监听指示信息用于指示所述 UE立即监听所述第二基站的 PDCCH; 或 者, 第二监听指示信息, 所述第二监听指示信息用于指示所述 UE在间隔设定 时间之后监听所述第二基站的 PDCCH; 或者, 第三监听指示信息, 所述第三 监听指示信息用于指示所述 UE转向监听所述第二基站的 PDCCH的起始时间, 所述起始时间通过系统帧号 SFN和子帧 sub frame表示。 本发明实施例提供的基站 80的工作流程请参照前面方法实施例的描述, 在这里不再重复。
现有小小区部署场景中, 用户设备 UE需要同时监听宏基站 (基站 80 )和 微基站(第二基站 ) 的 PDCCH上的数据传输, 不能做到合理的省电。 与现有 技术相比, 本发明实施例中令用户设备 UE在大部分时间只监听基站 80的 PDCCH; 当第二基站与 UE有数据传输时, 基站 80向 UE发送监听指示信息, 指示 UE监听第二基站的 PDCCH; 当 UE与第二基站之间的数据传输完毕后, 第二基站通知基站 80, 基站 80向 UE发送监听中止信息, 指示 UE停止监听第二 基站的 PDCCH。 从而使 UE能够在多数时间内只对基站 80的 PDCCH进行监听, 相比于一直监听两个基站的 PDCCH, 降低了 UE的电量消耗。
本发明实施例提供的用户设备及基站可以实现上述提供的方法实施例, 具体功能实现请参见方法实施例中的说明, 在此不再赘述。 本发明实施例提 供的省电方法、 用户设备及基站可以适用于用户设备同时对多个基站的 PDCCH的数据传输进行监听, 但不仅限于此。
本领域普通技术人员可以理解实现上述实施例方法中的全部或部分流 程, 是可以通过计算机程序来指令相关的硬件来完成, 所述的程序可存储于 一计算机可读取存储介质中, 该程序在执行时, 可包括如上述各方法的实施 例的流程。其中,所述的存储介质可为磁碟、光盘、只读存储记忆体( Read-Only Memory, ROM )或随机存^ ^己忆体 ( Random Access Memory, RAM )等。
以上所述, 仅为本发明的具体实施方式, 但本发明的保护范围并不局限 于此, 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内, 可轻易 想到的变化或替换, 都应涵盖在本发明的保护范围之内。 因此, 本发明的保 护范围应该以权利要求的保护范围为准。
