在宏小区和微小区混合部署的异构网络中, 如在双频双小区 (Dual Frequency-Dual Cell, DF-DC )、 双频三小区 ( Dual Frequency-3 cell, DF-3C ) 或双频四小区 DF-4C ( Dual Frequency-4 cell )部署场景中, 宏小区和微小区 在主载频上的发射功率一般不相等, 导致用户设备(User Equipment, UE )的 上行平衡点和下行平衡点不能对齐, 这里的上行平衡点为宏小区和微小区接 收 UE的信号的信号强度相同时该 UE所在的位置, 下行平衡点为该 UE接收 所述宏小区和微小区的信号的信号强度相同的位置。
如图 1所示, 在上述宏小区和微小区混合部署场景中, 针对主载频 F1 , 宏小区的发射功率为 43db, 微小区的发射功率为 30db, 上述 MF1下面表示 宏小区在载频 F1上的覆盖范围, PF1下面表示微小区在载频 F2上的覆盖范 围, MF1与 PF1的交点处即为 UE在载频 F1上的下行平衡点; 针对辅载频 F2,宏小区和微小区的发射功率都为 30db, 上述 MF2下面表示宏小区在载频 F2上的覆盖范围, PF2下面表示微小区在载频 F2上的覆盖范围, MF2与 PF2 的交点处即为 UE在载频 F2上的下行平衡点, 由于在 F2上, 宏小区和微小 区的发射功率是相等的, 该 UE在载频 F2上的下行平衡点与上行平衡点可以 认为是同一位置。
在上述部署场景中, 针对主载频 F1 , 当 UE在上行平衡点向微小区移动 时,微小区的下行链路未满足 1A事件触发条件,不能添加到 UE的激活集中, 无法控制 UE 的上行发送功率, 即使通过扩大小区独立偏置 CIO ( Cell Individual Offset ), 使得 UE能加入微小区到激活集中, UE仍然无法收到微小 区的功率控制命令, 因此微小区会受到 UE的上行强干扰, 降低了微小区的上 行容量; 同时, 在上行解耦后, UE的上行服务小区和下行服务小区在不同的 小区, 比如下行发送在宏小区, 上行接收在微小区, 此时, UE无法接收到微 小区的 E-HICH等控制信道的数据, 比如, UE在向微小区发送上行数据后, 将无法接收到微小区回复的反馈信息, 这样, UE可能会不断进行数据重传, 导致 UE的业务无法正常进行。
综上, 当 UE 没有在微小区的主载频信号覆盖范围内时, 微小区无法对 UE在主载频上的上行发送行为进行控制。 发明内容

如图 2所示, 为本发明实施例提供的进行上行信号控制的系统结构示意 图, 该系统包括:
第一网络侧设备 21 , 用于为用户设备 23确定上行控制配置信息, 将所述 上行控制配置信息通知给所述第二网络侧设备 22, 并将所述上行控制配置信 息发送给所述用户设备 23或指示所述第二网络侧设备 22将所述上行控制配 置信息发送给所述用户设备 23; 所述上行控制配置信息包括第二网络侧设备 22在第二载频上,发送控制所述用户设备 23在第一载频上的上行发送行为的 控制信息时, 所占用的控制信道的信息;
第二网络侧设备 22 ,用于接收第一网络侧设备 21发送的上行控制配置信 息, 并根据所述上行控制配置信息, 在所述第二载频上向所述用户设备 23发 送控制信息;
用户设备 23 , 用于接收第一网络侧设备 21或第二网络侧设备 22发送的 上行控制配置信息, 根据所述上行控制配置信息, 在所述第二载频上接收所 述第二网络侧设备 22发送的所述控制信息, 并根据所述第二网络侧设备 22 发送的控制信息控制自身在第一载频上的上行发送行为。
可选地,所述第一网络侧设备 21为无线网络控制器( RNC, Radio Network Controller ) , 所述第二网络侧设备 22为基站。
本发明实施例中, 第一载频和第二载频分别为两种不同的载频, 第一载 频可以为主载频, 第二载频可以为辅载频; 或者, 第一载频可以为辅载频, 第二载频为主载频;或者,第一载频为主载频,第二载频为 UE的非工作载频, 只承载控制信道, 不承载上下行数据信道; 本发明以下实施例中主要针对第 一载频为主载频, 第二载频为辅载频的场景进行具体说明。
在具体实施中, 以第一网络侧设备 21为 RNC, 第二网络侧设备 22为微 基站为例,本发明实施例可以配置微基站在辅载频上发送控制 UE在主载频上 的上行发送行为的控制信息, RNC在确定好在辅载频上发送该控制信息的上 行控制配置信息后, 可以将该上行控制配置信息直接发送给 UE, 也可以指示 需要对该 UE进行上行控制的微基站将该上行控制配置信息发送给 UE, 若该 微基站不属于该 RNC所控制, 该 RNC还可以将该上行控制配置信息发送给 控制该微基站的其它 RNC,由其它 RNC将该上行控制配置信息发送给该微基 站, 微基站再将该上行控制配置信息发送给 UE, 或由其它 RNC将该上行控 制配置信息直接发送给该 UE, 这里并不限定, UE在接收到该上行控制配置 信息后, 可以根据该上行控制配置信息的指示, 比如在 RNC配置的控制信道 上接收微基站发送的控制信息, 根据该控制信息, 对自身的上行发送行为进 行调节, 这样, 当 UE没有在微基站的主载频信号覆盖范围内时, 微基站还可 以采用辅载频对 UE在主载频的上行发送行为进行控制;上述第二网络侧设备 22为宏基站时, 也可以采用本发明实施例的方法, 这里并不限定。 可选地, 所述控制信息包括控制所述用户设备 23的上行发射功率的功率 控制信息, 所述控制信道包括用于发送所述功率控制信息的第一控制信道; 和 /或
所述控制信息包括针对所述用户设备 23在第一载频上发送给所述第二网 络侧设备 22的上行数据的反馈信息, 所述控制信道包括用于发送所述反馈信 息的第二控制信道。
需要说明的是,上述功率控制信息可以是直接指示 UE进行功率调整的信 息, 也可以是针对 UE请求的发射功率的授权信息;
可选地, 所述第一控制信道包括绝对授权信道 (E-DCH Absolute Grant Channel, E-AGCH)、相对授权信道( E-DCH Relative Grant Channel, E-RGCH ) 和部分专用物理控制信道(Fractional Dedicated Physical Control Channel , F-DPCH)中的至少一种;
所述第二控制信道包括确认指示信道 ( E-DCH HARQ Acknowledgement Indicator Channel, E-HICH )„
其中, 上述绝对授权信道、 相对授权信道和确认指示信道都属于增强专 用信道( Enhanced Dedicated Channel, E-DCH ), 上述 HARQ为混合自动重传 请求, 全称为 Hybrid Automatic Repeat Request。
本发明实施例中, 若第二载频上配置了 E-DCH, 则本发明实施例的所述 控制信道不包括现有的控制 UE在第二载频的上行发送行为的上行控制信道。
可选地, 若所述控制信息包括所述功率控制信息, 则所述用户设备 23根 据所述功率控制信息, 调整自身的上行发射功率;
若所述控制信息包括所述反馈信息, 则所述用户设备 23根据所述第二网 络侧设备 22发送的反馈信息, 判断所述第二网络侧设备 22是否正确接收到 所述用户设备 23发送的上行数据。
本发明实施例中,控制 UE的上行发送行为可以包括控制 UE的上行发射 功率, 也可以包括控制 UE发送上行数据等, 比如, UE在向微基站发送上行 数据后, 若没有接收到微基站反馈的确认(Acknowledgment, ACK )或否定 确认(Negative acknowledgment, NCK )信息, 就可能再次发送该上行数据, 导致产生多次不必要的数据重传行为, 采用本发明实施例, 微基站可以在上 述第二控制信道发送反馈的 ACK信息, 这样, 接收到 ACK信息的 UE就不 会进行不必要的数据重传。
可选地, 所述系统还包括: 第三网络侧设备 24, 用于在第一载频上向所 述用户设备 23发送控制所述用户设备 23在所述第一载频上的上行发送行为 的控制信息;
在具体实施中,所述 UE除了只通过考虑第二网络侧设备在第二载频上发 送的控制信息来控制自身的上行发送行为外, 还可以兼顾第二网络侧设备在 第二载频上发送的控制信息和第一网络侧设备管理下的第三网络侧设备在第 一载频上发送的控制信息; 也即,
所述 UE根据所述第二网络侧设备发送的控制信息,以及在所述第一载频 上接收的所述第一网络侧设备管理下的第三网络侧设备发送的控制信息, 控 制自身在第一载频上的上行发送行为。
可选地, 若所述控制信息包括所述功率控制信息, 则所述用户设备 23在 所述第二网络侧设备 22发送的功率控制信息和所述第三网络侧设备 24发送 的功率控制信息中的任意一种功率控制信息指示所述用户设备 23降低上行发 射功率时, 降低自身的上行发射功率;
若所述控制信息包括所述反馈信息, 则所述用户设备 23在所述第二网络 侧设备 22发送的反馈信息和所述第三网络侧设备 24发送的反馈信息中的任 意一种反馈信息包括确认 ACK信息时, 确定所述用户设备 23的上行数据发 送成功。
在具体实施中, 以第一网络侧设备为 RNC, 第二网络侧设备为微基站, 第三网络侧设备为宏基站为例, UE 除在第二载频上接收微基站发送的针对 UE在第一载频的上行发送行为的控制信息外,还有可能在第一载频上接收该 RNC管理下的宏基站发送的针对 UE在第一载频的上行发送行为的控制信息, 此时, UE根据在第二载频上接收的微基站发送的控制信息, 以及在第一载频 上接收的宏基站发送的控制信息, 控制自身在第一载频上的上行发送行为; 若所述 UE在第一载频和第二载频上接收的控制信息包括所述功率控制信息, 则 UE在所述微基站发送的功率控制信息和所述宏基站发送的功率控制信息 中的任意一种功率控制信息指示降低上行发射功率时, 降低自身的上行发射 功率, 在所述微基站发送的功率控制信息和所述宏基站发送的功率控制信息 都指示提高上行发射功率时, 提高自身的上行发射功率; 若所述控制信息包 括所述反馈信息,则 UE在所述微基站发送的反馈信息和所述宏基站发送的反 馈信息中的任意一种反馈信息包括 ACK信息时, 确定所述 UE的上行数据发 送成功。
比如, 第一载频为主载频, 第二载频为辅载频, UE既在辅载频上接收微 基站发送的针对主载频的上行控制信息, 还在主载频上接收宏基站发送的针 对该主载频的上行控制信息,若 UE同时在主载频和辅载频上接收到针对主载 频的上行控制信息, 则 UE根据这两个上行控制信息,确定自身在主载频的上 行发送行为,比如, UE判断在主载频和辅载频上接收的针对主载频的 E-HICH 信息中是否存在至少一个 E-HICH信息包括 ACK信息, 若是, 则认为自己在 主载频上的上行数据发送成功, 并确定不再进行上行数据重传; UE判断在主 载频和辅载频上接收的针对主载频的功率控制信息中, 是否有一个载频上的 功率控制信息指示降低上行发射功率, 若有, 则降低自身在主载频上的上行 发射功率, 只有当在主载频和辅载频上接收的针对主载频的功率控制信息都 指示提高上行发射功率时, 才提高自身的上行发射功率;
在实际实施中, 若 UE在主载频和辅载频上同时接收到上行控制信息时, 也可以不必同时考虑主载频和辅载频上的控制信息, 比如,可以配置 UE在主 载频和辅载频上同时接收到上行控制信息时, 只根据在主载频上接收到的上 行控制信息或只根据在辅载频上接收到的上行控制信息, 控制自身的上行发 送行为; 在具体实施中,在配置了 UE在主载频上和辅载频上接收上行控制信 息的控制信道后,可以通过物理层信令具体通知 UE采用哪种方式控制自身的 上行发送行为。 可选地, 所述用户设备 23接收所述上行控制配置信息之前, 上报自身的 支持能力信息;
相应地, 所述第一网络侧设备 21在接收到所述用户设备 23上报的支持 能力信息后, 根据用户设备 23的支持能力信息, 判断该用户设备 23是否支 持在所述第二载频上接收所述控制信息, 若确定该用户设备 23支持在所述第 二载频上接收所述控制信息, 再为用户设备 23配置所述上行控制配置信息。
在具体实施过程中, UE可以向 RNC上报自身的支持能力信息, 比如, 其中可以包括该 UE 支持或不支持在辅载频上接收微基站发送的控制信息的 信息, RNC在确定 UE支持在第二载频上接收微基站发送的控制信息后, 再 为该 UE确定所述上行控制配置信息; UE也可以不向 RNC上报自身的支持 能力信息, 这时, RNC默认在 DF-DC、 DF-3C和 DF-4C等部署场景下, 具备 DF-DC、 DF-3C和 DF-4C能力的 UE支持在第二载频上接收微基站发送的控 制信息。
可选地, 所述用户设备 23根据所述上行控制配置信息, 在所述第二载频 上接收所述控制信息之前 ,接收所述第二网络侧设备 22发送的接收指示信息, 所述接收指示信息用于指示所述用户设备 23在所述第二载频上接收所述控制 信息。
在具体实施过程中, UE在接收到所述上行控制配置信息后, 确定可以根 据该上行控制配置信息中指示的控制信道接收第二网络侧设备发送的控制信 息, 之后, 第二网络侧设备在确定需要向 UE发送所述控制信息后, 可以向该 UE发送接收指示信息, UE在接收到该接收指示信息后, 切换到所述第二载 频接收所述控制信息。
可选地,所述第一网络侧设备 21在确定满足以下条件中的一种或几种时, 确定所述上行控制配置信息, 或者, 第二网络侧设备 22在确定满足以下条件 中的一种或几种时, 向用户设备 23发送所述控制信息:
所述用户设备 23的信号测量结果满足主载频或辅载频的信号测量报告的 事件; 所述用户设备 23进入所述第一载频的上行平衡点和所述第一载频的下行 平衡点之间的区域;
所述用户设备 23的上行和下行服务小区为不同的小区, 且所述第二网络 侧设备 22为所述上行服务小区提供服务;
所述用户设备 23对所述第二网络侧设备 22的上行干扰值超过设定干扰 门限值;
所述第二载频的负载超过设定负载门限值;
当前主载频无法从第一载频切换到第二载频。
在具体实施过程中,第一网络侧设备可以预先为 UE确定上行控制配置信 息, 并发送给 UE, 也可以在确定第二网络侧设备需要对 UE进行上行信号控 制后, 再为 UE确定上行控制配置信息, 并发送给 UE; 当第一网络侧设备预 先为 UE确定上行控制配置信息时,第二网络侧设备可以在根据以上条件确定 需要对 UE进行上行信号控制时, 向 UE发送控制信息; 第二网络侧设备对 UE进行上行信号控制可以包括控制 UE的上行发射功率, 比如, 在 UE的信 号测量结果满足主载频或辅载频的信号测量报告的事件 (如 1A事件等) 时, 采用本发明实施例对 UE进行上行信号控制; 再比如, 在确定 UE进入上下行 不平衡区域, 即进入针对主载频的上行平衡点和针对主载频的下行平衡点之 间的区域时, 就可以确定需要对该 UE进行上行功率控制, 因为微基站(第二 微基站的下行链路未满足 1A事件, 不能添加到 UE的激活集中, 即使通过扩 展小区独立偏置(Cell Individual Offset, CIO ), 使得微基站能加入到 UE的激 活集中, UE还是无法收到微基站发送的功率控制命令, 也即微基站无法在主 载频上控制 UE的上行发射功率, 会受到 UE的上行强干扰, 降低自身的上行 容量, 这时, 就可以采用本发明实施例, 实现微基站对 UE的上行功率控制; 再比如, 若确定 UE对所述第二网络侧设备的上行干扰值超过设定干扰门限 值, 则确定微基站受到 UE的上行强干扰, 需要对 UE进行上行功率控制; 第 二网络侧设备对 UE进行上行信号控制也可以包括控制 UE进行上行数据发 送, 比如, 在进行上行解耦后, UE的上行和下行服务小区在不同的小区, 比 如, UE的下行发送在宏基站, 上行接收在微基站, UE将无法接收到微基站 发送的下行控制信息, 比如 UE在向微基站发送上行数据后,将无法接收到微 基站在 E-HICH 上反馈的确认信息, UE会不断进行数据重传, 将无法保证 UE业务的正常进行;
在具体实施过程中, 若 UE在当前主载频(第一载频)上对微基站的上行 干扰较大, 可以将主载频从第一载频切换到第二载频, 以避免干扰, 但是, 若第二载频的负载超高设定负载门限值, 将无法进行主载频切换, 或者, 由 于第二载频的下行链路质量较差, 在将主载频从第一载频切换到第二载频时 切换失败, 这时, 可以采用本发明实施例对 UE进行上行功率控制, 以避免干 扰。
可选地, 上述实施例中, 判断用户设备 23是否从上行平衡点进入了上下 行不平衡区域可以有以下几种方式:
可以根据在主载频或辅载频上小区的无线信号测量事件,判断 UE是否从 上行平衡点进入了上下行不平衡区域; 其中, 无线信号测量事件的无线信号 测量量可以是接收信号码功率(Received Signal Code Power, RSCP )、 码片能 量与干扰和噪声的比值(Ec/No )或路径损失(pathloss )等, 在具体实施中, 可以在主载频或辅载频上配置同频测量事件的门限, 以辅载频为例, 可以给 UE配置 1A或 1D等事件的门限值, 当 UE从宏小区进入到上行平衡点时,触 发微小区的 1A或 1D事件的上报,第一网络侧设备在收到该 1A或 1D事件后 确定 UE进入上下行不平衡区域。
基于同一发明构思, 本发明实施例中还提供了以下进行上行信号控制的 装置及方法, 由于这些装置和方法解决问题的原理与上述系统相似, 因此这 些装置的实施可以参见系统的实施, 重复之处不再赘述。

如图 9所示, 为本发明实施例一提供的上行信号控制方法流程图, 包括 以下步骤:
S901 : 第一网络侧设备为 UE确定上行控制配置信息,所述上行控制配置 信息包括第二网络侧设备在第二载频上,发送控制所述 UE在第一载频上的上 行发送行为的控制信息时, 所占用的控制信道的信息;
S902: 所述第一网络侧设备将所述上行控制配置信息通知给所述第二网 络侧设备,并将所述上行控制配置信息发送给所述 UE或指示所述第二网络侧 设备将所述上行控制配置信息发送给所述 UE。
可选地, 所述第一网络侧设备为无线网络控制器 (RNC, Radio Network Controller ), 所述第二网络侧设备为基站。
本发明实施例中, 第一载频和第二载频分别为两种不同的载频, 第一载 频可以为主载频, 第二载频可以为辅载频; 或者, 第一载频可以为辅载频, 第二载频为主载频;或者,第一载频为主载频,第二载频为 UE的非工作载频, 只承载控制信道, 不承载上下行数据信道; 本发明以下实施例中主要针对第 一载频为主载频, 第二载频为辅载频的场景进行具体说明。
在具体实施中, 以第一网络侧设备为 RNC, 第二网络侧设备为微基站为 例,本发明实施例可以配置微基站在辅载频上发送控制 UE在主载频上的上行 发送行为的控制信息, RNC在确定好在辅载频上发送该控制信息的上行控制 配置信息后, 可以将该上行控制配置信息直接发送给 UE, 也可以指示可能需 要对该 UE进行上行控制的微基站将该上行控制配置信息发送给 UE, 若该微 基站不属于该 RNC所控制, 该 RNC还可以将该上行控制配置信息发送给控 制该微基站的其它 RNC, 由其它 RNC将该上行控制配置信息发送给该微基 站, 微基站再将该上行控制配置信息发送给 UE, 或由其它 RNC将该上行控 制配置信息直接发送给该 UE, 这里并不限定, UE在接收到该上行控制配置 信息后, 可以根据该上行控制配置信息的指示, 比如在 RNC配置的控制信道 上接收微基站发送的控制信息, 根据该控制信息, 对自身的上行发送行为进 行调节, 这样, 当 UE没有在微基站的主载频信号覆盖范围内时, 微基站还可 以采用辅载频对 UE在主载频的上行发送进行控制;上述第二网络侧设备为宏 基站时, 也可以采用本发明实施例的方法, 这里并不限定。
可选地, 所述控制信息包括控制所述 UE 的上行发射功率的功率控制信 息, 所述控制信道包括用于发送所述功率控制信息的第一控制信道; 和 /或, 所述控制信息包括针对所述 UE在第一载频上发送给所述第二网络侧设备的 上行数据的反馈信息, 所述控制信道包括用于发送所述反馈信息的第二控制 信道。
需要说明的是,上述功率控制信息可以是直接指示 UE进行功率调整的信 息, 也可以是针对 UE请求的发射功率的授权信息;
本发明实施例中,控制 UE的上行发送行为可以包括控制 UE的上行发射 功率, 也可以包括控制 UE发送上行数据等, 比如, UE在向微基站发送上行 数据后, 若没有接收到微基站反馈的确认(Acknowledgment, ACK )或否定 确认(Negative acknowledgment, NCK )信息, 就可能再次发送该上行数据, 导致产生多次不必要的数据重传行为, 采用本发明实施例, 微基站可以在上 述第二控制信道发送反馈的确认信息, 这样,接收到确认信息的 UE就不会进 行不必要的数据重传。
可选地, 所述第一控制信道包括绝对授权信道 (E-DCH Absolute Grant Channel, E-AGCH)、相对授权信道( E-DCH Relative Grant Channel, E-RGCH ) 和部分专用物理控制信道(Fractional Dedicated Physical Control Channel , F-DPCH)中的至少一种;
所述第二控制信道包括确认指示信道 ( E-DCH HARQ Acknowledgement Indicator Channel, E-HICH )„
其中, 上述绝对授权信道、 相对授权信道和确认指示信道都属于增强专 用信道( Enhanced Dedicated Channel, E-DCH ), 上述 HARQ为混合自动重传 请求, 全称为 Hybrid Automatic Repeat Request。
本发明实施例中,若第二载频上配置了增强专用信道( Enhanced Dedicated Channel, E-DCH ), 则本发明实施例的所述控制信道不包括现有的控制 UE在 第二载频的上行发送行为的上行控制信道。
在具体实施过程中, UE除了只通过考虑第二网络侧设备在第二载频上发 送的控制信息来控制自身的上行发送行为外, 还可以兼顾第二网络侧设备在 第二载频上发送的控制信息和第一网络侧设备管理下的第三网络侧设备在第 一载频上发送的控制信息; 也即, UE根据所述第二网络侧设备发送的控制信 息, 以及在所述第一载频上接收的所述第一网络侧设备管理下的第三网络侧 设备发送的控制信息, 控制自身在第一载频上的上行发送行为。
具体地,若所述控制信息包括所述功率控制信息, 则所述 UE在所述第二 网络侧设备发送的功率控制信息和所述第三网络侧设备发送的功率控制信息 中的任意一种功率控制信息指示所述 UE降低上行发射功率时,降低自身的上 行发射功率, 在所述第二网络侧设备发送的功率控制信息和所述第三网络侧 设备发送的功率控制信息都指示提高上行发射功率时, 提高自身的上行发射 功率; 若所述控制信息包括所述反馈信息, 则所述 UE在所述第二网络侧设备 发送的反馈信息和所述第三网络侧设备发送的反馈信息中的任意一种反馈信 息包括确认 ACK信息时, 确定所述 UE的上行数据发送成功。
在具体实施中, 以第一网络侧设备为 RNC, 第二网络侧设备为微基站, 第三网络侧设备为宏基站为例, UE 除在第二载频上接收微基站发送的针对 UE在第一载频的上行发送行为的控制信息外, 还有可能在第一载频上接收该 RNC管理下的宏基站发送的针对 UE在第一载频的上行发送行为的控制信息, 此时, UE根据在第二载频上接收的微基站发送的控制信息, 以及在第一载频 上接收的宏基站发送的控制信息, 控制自身在第一载频上的上行发送行为; 若所述 UE在第一载频和第二载频上接收的控制信息包括所述功率控制信息, 则 UE在所述微基站发送的功率控制信息和所述宏基站发送的功率控制信息 中的任意一种功率控制信息指示降低上行发射功率时, 降低自身的上行发射 功率, 在所述微基站发送的功率控制信息和所述宏基站发送的功率控制信息 都指示提高上行发射功率时, 提高自身的上行发射功率; 若所述控制信息包 括所述反馈信息,则 UE在所述微基站发送的反馈信息和所述宏基站发送的反 馈信息中的任意一个反馈信息包括确认 ACK信息时, 确定所述 UE的上行数 据发送成功。
比如, 第一载频为主载频, 第二载频为辅载频, UE既在辅载频上接收微 基站发送的针对主载频的上行控制信息, 还在主载频上接收宏基站发送的针 对该主载频的上行控制信息,若 UE同时在主载频和辅载频上接收到针对主载 频的上行控制信息, 则 UE根据这两个上行控制信息,确定自身在主载频的上 行发送行为,比如, UE判断在主载频和辅载频上接收的针对主载频的 E-HICH 信息中是否存在至少一个 E-HICH信息包括确认( ACK )信息, 若是, 则认 为自身在主载频上的上行数据发送成功, 并确定不再进行上行数据重传; UE 判断在主载频和辅载频上接收的针对主载频的功率控制信息中, 是否有一个 载频上的功率控制信息指示降低上行发射功率, 若有, 则降低自身在主载频 上的上行发射功率; UE只有当在主载频和辅载频上接收的针对主载频的功率 控制信息都指示提高上行发射功率时, 才提高自身的上行发射功率;
在实际实施中, 若 UE在主载频和辅载频上同时接收到上行控制信息时, 也可以不必同时考虑主载频和辅载频上的控制信息, 比如,可以配置 UE在主 载频和辅载频上同时接收到上行控制信息时, 只根据在主载频上接收到的上 行控制信息或只根据在辅载频上接收到的上行控制信息, 控制自身的上行发 送行为; 在具体实施中,在配置了 UE在主载频上和辅载频上接收上行控制信 息的控制信道后,可以通过物理层信令具体通知 UE采用哪种方式控制自身的 上行发送行为。
可选地, 所述第一网络侧设备确定所述上行控制配置信息之前, 还包括: 所述第一网络侧设备接收所述 UE上报的支持能力信息,并根据所述支持 能力信息, 确定所述 UE支持在所述第二载频上接收所述控制信息。
在具体实施过程中, UE可以向 RNC上报自身的支持能力信息, 比如, 其中可以包括该 UE 支持或不支持在辅载频上接收微基站发送的控制信息的 信息, RNC在确定 UE支持在第二载频上接收微基站发送的控制信息后, 再 为该 UE确定所述上行控制配置信息; UE也可以不向 RNC上报自身的支持 能力信息, 这时, RNC默认在 DF-DC、 DF-3C和 DF-4C等部署场景下, 具备 DF-DC、 DF-3C和 DF-4C能力的 UE支持在第二载频上接收微基站发送的控 制信息。
可选地, 第一网络侧设备确定上行控制配置信息, 包括:
所述第一网络侧设备在确定满足以下条件中的一种或几种时, 确定所述 上行控制配置信息:
所述 UE的信号测量结果满足主载频或辅载频的信号测量报告的事件; 所述 UE进入所述第一载频的上行平衡点和所述第一载频的下行平衡点 之间的区域;
所述 UE的上行和下行服务小区为不同的小区,且所述第二网络侧设备为 所述上行服务小区提供服务; 所述第二载频的负载超过设定负载门限值;
当前主载频无法从第一载频切换到第二载频。
在具体实施过程中,第一网络侧设备可以预先为 UE确定上行控制配置信 息, 并发送给 UE, 也可以在确定第二网络侧设备需要对 UE进行上行信号控 制后, 再为 UE确定上行控制配置信息, 并发送给 UE; 当第一网络侧设备预 先为 UE确定上行控制配置信息时,第二网络侧设备可以在根据以上条件确定 需要对 UE进行上行信号控制时, 向 UE发送控制信息; 第二网络侧设备对 UE进行上行信号控制可以包括控制 UE的上行发射功率, 比如, 在 UE的信 号测量结果满足主载频或辅载频的信号测量报告的事件 (如 1A事件等) 时, 采用本发明实施例对 UE进行上行信号控制; 再比如, 在确定 UE进入上下行 不平衡区域, 即进入针对主载频的上行平衡点和针对主载频的下行平衡点之 间的区域时, 可以确定需要对该 UE进行上行功率控制, 因为微基站(第二网 基站的下行链路未满足 1A事件, 不能添加到 UE的激活集中, 即使通过扩展 小区独立偏置(Cell Individual Offset, CIO ), 使得微基站能加入到 UE的激活 集中, UE还是无法收到微基站发送的功率控制命令, 也即微基站无法在主载 频上控制 UE的上行发射功率, 会受到 UE的上行强干扰, 降低自身的上行容 量, 这时, 就可以采用本发明实施例, 实现微基站对 UE的上行功率控制; 再 则确定微基站受到 UE的上行强干扰, 需要对 UE进行上行功率控制; 第二网 络侧设备对 UE进行上行信号控制也可以包括控制 UE进行上行数据发送, 比 如, 在进行上行解耦后, UE的上行和下行服务小区在不同的小区, 比如, UE 的下行发送在宏基站, 上行接收在微基站, UE将无法接收到微基站发送的下 行控制信息, 比如 UE在向微基站发送上行数据后, 将无法接收到微基站在 E-HICH上反馈的确认信息, UE会不断进行数据重传, 将无法保证 UE业务 的正常进行; 在具体实施过程中, 若 UE在当前主载频(第一载频)上对微基站的上行 干扰较大, 可以将主载频从第一载频切换到第二载频, 以避免干扰, 但是, 若第二载频的负载超高设定负载门限值, 将无法进行主载频切换, 或者, 由 于第二载频的下行链路质量较差, 在将主载频从第一载频切换到第二载频时 切换失败, 这时, 可以采用本发明实施例对 UE进行上行功率控制, 以避免干 扰。
可选地,上述实施例中,判断 UE是否从上行平衡点进入了上下行不平衡 区域可以有以下几种方式:
可以根据在主载频或辅载频上小区的无线信号测量事件,判断 UE是否从 上行平衡点进入了上下行不平衡区域; 其中, 无线信号测量事件的无线信号 测量量可以是 RSCP、 Ec/No或 pathloss等, 在具体实施中, 可以在主载频或 辅载频上配置同频测量事件的门限,以辅载频为例 ,可以给 UE配置 1A或 1D 等事件的门限, 当 UE从宏小区进入到上行平衡点时,触发微小区的 1A或 1D 事件的上报, 第一网络侧设备在收到该 1A或 1D事件后确定 UE进入上下行 不平衡区。
基于同一发明构思, 本发明实施例还提供了以下基于第二网络侧设备侧 的上行信号控制方法, 具体实施可参见上述实施例, 重复之处, 不再赘述。

所述 UE的上行和下行服务小区为不同的小区,且所述第二网络侧设备为 所述上行服务小区提供服务; 所述第二载频的负载超过设定负载门限值;
当前主载频无法从第一载频切换到第二载频。 在具体实施过程中,若第一网络侧设备预先为 UE确定上行控制配置信息 并发送给 UE, 第二网络侧设备可以在满足以上条件时, 根据所述上行控制配 置信息向 UE发送控制信息, 若第一网络侧设备在满足以上条件时, 才为 UE 确定上行控制配置信息并发送给 UE, 则第二网络侧设备在接收到第一网络侧 设备确定的上行控制配置信息后,即可根据该上行控制配置信息向 UE发送控 制信息。
基于同一发明构思,本发明实施例还提供了以下基于 UE侧的上行信号控 制方法, 具体实施可参见上述实施例的描述, 重复之处, 不再赘述。

需要说明的是, UE除可能在第二载频上接收到基站发送的控制信息外, 还有可能在第一载频上同时接收到宏基站发送的控制信息, 当微基站发送的 控制信息与宏基站发送的控制信息相互矛盾时, UE以减少干扰、 减少重传次 数为原则,只要其中一个基站要求降低发射功率, UE就降低自身的发射功率, 只要接收到其中一个基站反馈的确认信息, 则确定上行数据已发送成功。
