Description

异构网中功率配置的控制方法及用户设备
【技术领域】
本发明属于无线通信技术领域，具体涉及异构网中功率配置的控制方法及用户设备。
【背景技术】
为了增强网络侧的处理能力，现有技术提供了一种异构网络（Hetnet，Heterogeneous network）技术，即在覆盖范围大的宏基站所覆盖的小区内设置微基站，使用微基站搭配宏基站来组网。
上述现有技术Hetnet中，会出现一个软切换区，当用户设备处于该软切换区时，微基站接收到用户设备的上行信道功率会大于宏基站接收到的用户设备的上行信道功率。而Hetnet中在该软切换区，用户设备同时受到微基站和宏基站的功率控制，且功率控制的准则是：只要有一个Hetnet内的基站发送“降功率”指令，则用户设备就响应为降功率操作。只有当所有基站都向用户设备发送“升功率”指令，用户设备才会响应为升功率操作。这样将直接影响上行高速专用物理控制信道(HS-DPCCH)的解调性能。
现有的一种做法是当用户设备处于软切换区时，自行增大专用物理控制信道（DPCCH）功率来保证HS-DPCCH的解调性能。但是这样又会导致增强专用物理数据信道(E-DPDCH)的功率也随之相应增大，从而导致E-DPDCH功率过高而浪费Hetnet的负载资源。且当用户设备处于软切换区时，微基站接收到用户设备的信号很强，而宏基站接收到用户设备的信号很弱，当用户设备E-DPDCH功率增大，使得微基站接收的用户设备的信号更强，必然对宏基站接收用户设备的信号造成干扰，宏基站向用户设备发送降功率指令，用户设备又会进一步响应降低功率指令而降低功率，从而无法实现增大DPCCH功率保证HS-DPCCH解调性能的目的。

【具体实施方式】
以下描述中，为了说明而不是为了限定，提出了诸如特定系统结构、接口、技术之类的具体细节，以便透彻理解本申请。然而，本领域的技术人员应当清楚，在没有这些具体细节的其它实施例中也可以实现本申请。在其它情况中，省略对众所周知的装置、电路以及方法的详细说明，以免不必要的细节妨碍本申请的描述。
参阅图1，图1是实现本申请功率配置的控制方法的系统（即异构网组网系统）的一个实施例的示意图。本实施例的异构网组网系统包括：服务基站110、辅助基站120以及用户设备130。其中，用户设备130可分别与服务基站110以及辅助基站120建立无线连接，而服务基站110与辅助基站120之间同样可进行数据传输。在本实施例中，将宏基站作为服务基站110，而将微基站作为辅助基站120。
通常，服务基站110所覆盖的小区内的用户设备130均可与服务基站110通讯，而辅助基站120所覆盖的小区内的用户设备130均可与辅助基站120进行通讯，但是，由于这里服务基站110与辅助基站120组成了异构网络，所以，服务基站110所覆盖的小区和辅助基站120所覆盖的小区之间形成了三个区域。在区域A中，服务基站110收到用户设备130的信号很强，用户设备130收到服务基站110的信号也很强，辅助基站120收到用户设备130的信号很弱，用户设备130收到辅助基站120的信号也很弱；在区域B中，服务基站110收到用户设备130的信号很弱（图中虚线所示），用户设备130收到服务基站110的信号很强（图中实线所示），辅助基站120收到用户设备130的信号很强（图中实线所示），用户设备130收到辅助基站120的信号很弱（图中虚线所示）；在区域C中，服务基站110收到用户设备130的信号很弱，用户设备130收到服务基站110的信号也很弱，辅助基站120收到用户设备130的信号很强，用户设备130收到辅助基站120的信号也很强。所以，区域A和C称作平衡区域，而区域B称作软切换区即不平衡区域。
在本实施例中，服务基站110与辅助基站120之间可以直接进行通讯，在其它的实施例中，服务基站110与辅助基站120之间也可以通过无线网络控制器（RNC，Radio Network Controller）进行通讯。
当用户设备130处于软切换区时，用户设备130同时受到微基站和宏基站的功率控制，且功率控制的准则是：只要有一个激活集内的小区发送“降功率”指令，则用户设备130就响应为降功率操作。只有当所有小区都向用户设备130发送“升功率”指令，用户设备130才会响应为升功率操作。这样将直接影响上行高速专用物理控制信道(HS-DPCCH)的解调性能。
本申请有鉴于此，提供一种异构网中功率配置的控制方法，目的在于实现，当用户设备处于异构网的软切换区时，既能实现与基站之间正常通讯，也不影响上行专用物理控制信道的解调性能。
请参阅图2，图2是本申请异构网中功率配置的控制方法一个实施例的流程图，本实施例异构网中功率配置的控制方法包括：
步骤S101：用户设备当用户设备处于上下行平衡点之间以宏站为服务基站的软切换区时，增大专用物理控制信道的功率以使服务基站能正常接收来自用户设备的信号；
当用户设备处于上下行平衡点之间以宏站为服务基站的软切换区时，增大专用物理控制信道(DPCCH)的功率，这样能使服务基站能够正常接收来自用户设备的信号。
步骤S102：调整增强专用物理数据信道的功率偏置至第一功率偏置，所述第一功率偏置为用户设备的最优功率偏置的平坦区域的任何一个值；
在增大DPCCH的功率后，需要及时调整增强专用物理数据信道(E-DPDCH)的功率偏置，否则，没法真正实现增大DPCCH以保证DPCCH的性能的目的。因为跟随DPCCH的功率增大，E-DPDCH的功率偏置也相应增大，从而导致E-DPDCH的功率超出正常需求，由于外环的调控，会控制降低功率，从而使用户设备又进一步响应降功率指令而使用户设备的发射功率再度降低。
因此，在增大DPCCH的功率后，及时调整E-DPDCH的功率偏置至第一功率偏置，该第一功率偏置为用户设备的最优功率偏置的平坦区域的任何一个值。控制E-DPDCH的功率偏置在用户设备的最优功率偏置的平坦区域，则用户设备的接收总功率相同。因此，通过这种方式，既达到增大DPCCH功率实现正常通讯的目的，也不会影响DPCCH的解调性能。
通过上述实施例的阐述，可以理解，本申请实施例提供异构网中功率配置的控制方法，当用户设备处于异构网的软切换区时，增大专用物理控制信道的功率以使所述服务基站能正常接收来自用户设备的信号；同时调整增强专用物理数据信道的功率偏置至第一功率偏置，第一功率偏置为用户设备的最优功率偏置的平坦区域的任何一个值。通过这种方式，当用户设备处于软切换区时，能够快速调整功率以适应信号传输需要，且能保证HS-DPCCH的解调性能不受影响。
为进一步解释本申请的技术方案，以下通过更加详细的实现过程来解释本申请异构网中功率配置的控制方法。
请参阅图3，图3是本申请异构网中功率配置的控制方法一个实施例的流程图，异构网中功率配置的控制方法包括：
步骤S201：判断用户设备是否处于上下行平衡点之间以宏站为服务基站的软切换区；
用户设备判断自己是否处于上下行平衡点之间以宏站为服务基站的软切换区，比如用户设备可以通过自身接收的信号状况判断自己的位置是否处于软切换区。当用户设备检测到自己的位置已经处于上下行平衡点之间以宏站为服务基站的软切换区时，执行步骤S202，否则，执行步骤S204。
步骤S202：增大专用物理控制信道的功率以使服务基站能正常接收来自用户设备的信号；
用户设备处于上下行平衡点之间以宏站为服务基站的软切换区时，抬升专用DPCCH的功率，这样能使服务基站能够正常接收来自用户设备的信号。
在实际应用中，本申请实施例增大DPCCH的功率可以有两种实现方式，一种实现方式是将DPCCH的信噪比目标值(SIR target)由初始信噪比目标值(SIR0 )调至第一信噪比目标值(SIR1 )，以使服务基站能正常接收来自用户设备的信号，其中，SIR1 大于SIR0 ，即将SIR target调高。
另一种实现方式是将DPCCH的发射功率由初始发射功率(Ecdpcch0 )调整为第一发射功率(Ecdpcch1 )，以使服务基站能正常接收来自用户设备的信号，其中，Ecdpcch1 大于Ecdpcch0 ，即将发射功率调高。
步骤S203：调整增强专用物理数据信道的功率偏置至第一功率偏置，第一功率偏置为用户设备的最优功率偏置的平坦区域的任何一个值；
在增大DPCCH的功率后，及时调整E-DPDCH的功率偏置至第一功率偏置。其中，针对增大DPCCH的功率的两种实现方式，通过调整SIR target和调整发射功率来增大DPCCH的功率。调整E-DPDCH的功率偏置至第一功率偏置也有相应的以下几种实现方式：
当通过调整SIR target来增大DPCCH的功率时，可以控制第一功率偏置满足： PO1 =(SIR0 /SIR1 )×(PO0 +POw ) - POw ，其中，PO1 为第一功率偏置，SIR0 为用户设备未处于软切换区时专用物理控制信道的初始信噪比目标值，PO0 为用户设备未处于软切换区时增强专用物理数据信道的初始功率偏置，SIR1 为用户设备处于软切换区时专用物理控制信道经调整后的第一信噪比目标值，POw 为用户设备未处于软切换区时，高速专用物理控制信道的功率偏置POhsdpcch 、增强专用物理控制信道的功率偏置POedpcch 、专用物理数据信道的功率偏置POdpdch 以及专用物理控制信道的功率偏置1的求和，POw = POhsdpcch +POedpcch +POdpdch +1。
因为平坦区接收总功率相同，即E0 =E1 ,其中,
E0 /N0 =(SIR0 /256)×(PO0 +POhsdpcch +POedpcch +POdpdch +1)；
E1 /N0 =(SIR1 /256)×(PO1 +POhsdpcch +POedpcch +POdpdch +1),
所以：
PO1 =(SIR0 /SIR1 )×(PO0 +POhsdpcch +POedpcch +POdpdch +1)-(POhsdpcch +POedpcch +POdpdch +1)，若POm -POn 为用户设备的最优功率偏置的平坦区域，则POm ≤PO1 ≤POn 。
当通过调整发射功率来增大DPCCH的功率时，可以控制第一功率偏置满足： PO1 =(Ecdpcch0 /Ecdpcch1 )×(PO0 +POw ) - POw ，其中，PO1 为第一功率偏置，Ecdpcch0 为用户设备未处于软切换区时专用物理控制信道的初始发射功率，PO0 为用户设备未处于软切换区时增强专用物理数据信道的初始功率偏置，Ecdpcch1 为用户设备处于软切换区时专用物理控制信道的经调整后的第一发射功率，POw 为用户设备未处于所述软切换区时，高速专用物理控制信道的功率偏置POhsdpcch 、增强专用物理控制信道的功率偏置POedpcch 、专用物理数据信道的功率偏置POdpdch 以及专用物理控制信道的功率偏置1的求和，POw =POhsdpcch +POedpcch +POdpdch +1。
因为平坦区接收总功率相同，即：E0 =E1 ，其中，
E0 =Ecdpcch0 ×(PO0 +POhsdpcch +POedpcch +POdpdch +1),
E1 =Ecdpcch1 ×(PO1 +POhsdpcch +POedpcch +POdpdch +1)，
所以：PO1 =(Ecdpcch0 /Ecdpcch1 )×(PO0 +POhsdpcch +POedpcch +POdpdch +1)- (POhsdpcch +POedpcch +POdpdch +1)，若POm -POn 为用户设备的最优功率偏置的平坦区域，则POm ≤PO1 ≤POn 。
如果功率调整是以信令的形式通知到用户终端时，可以控制第一功率偏置满足：PO1 =(1/POdpcch )×(PO0 +POw )- POw ，其中，PO1 为第一功率偏置，PO0 为用户设备未处于软切换区时增强专用物理数据信道的初始功率偏置，POdpcch 为用户设备处于所述软切换区时专用物理控制信道的功率偏置，POw 为用户设备未处于软切换区时，高速专用物理控制信道的功率偏置POhsdpcch 、增强专用物理控制信道的功率偏置POedpcch 、专用物理数据信道的功率偏置POdpdch 以及专用物理控制信道的功率偏置1的求和，POw =POhsdpcch +POedpcch +POdpdch +1。
因为平坦区接收总功率相同，即：E0 =E1 ，其中，
E0 =Ecdpcch0 ×(PO0 +POhsdpcch +POedpcch +POdpdch +1)，
E1 =Ecdpcch0 ×POdpcch ×(PO1 +POhsdpcch +POedpcch +POdpdch +1)，
所以:PO1 =(1/POdpcch )×(PO0 +POhsdpcch +POedpcch +POdpdch +1)- (POhsdpcch +POedpcch +POdpdch +1), 若POm -POn 为用户设备的最优功率偏置的平坦区域，则POm ≤PO1 ≤POn 。
步骤S204：不执行动作；
当用户设备检测到自己的位置未处于上下行平衡点之间以宏站为服务基站的软切换区时，则不执行动作。
请参阅图4，图4为本申请用户设备一个实施例的结构示意图，用户设备130包括判断模块11和控制模块12，其中：
判断模块11用于判断用户设备是否处于上下行平衡点之间以宏站为服务基站的软切换区，并将判断结果输出给控制模块12；
判断模块11判断用户设备是否处于上下行平衡点之间以宏站为服务基站的软切换区，比如判断模块11可以通过用户设备接收的信号状况判断用户设备的位置是否处于软切换区，并将判断结果输出给控制模块12。
控制模块12用于当用户设备处于上下行平衡点之间以宏站为服务基站的软切换区时，增大DPCCH的功率以使服务基站能正常接收来自用户设备的信号，并调整E-DPDCH的功率偏置至第一功率偏置，第一功率偏置为用户设备的最优功率偏置的平坦区域的任何一个值。
当用户设备处于上下行平衡点之间以宏站为服务基站的软切换区时，控制模块12增大DPCCH的功率，这样能使服务基站能够正常接收来自用户设备的信号。
在实际应用中，本申请实施例控制模块12增大DPCCH的功率可以有两种实现方式，一种实现方式是将DPCCH的信噪比目标值(SIR target)由初始信噪比目标值(SIR0 )调至第一信噪比目标值(SIR1 )，以使服务基站能正常接收来自用户设备的信号，其中，SIR1 大于SIR0 ，即将SIR target调高。
另一种实现方式是控制模块12将DPCCH的发射功率由初始发射功率(Ecdpcch0 )调整为第一发射功率(Ecdpcch1 )，以使服务基站能正常接收来自用户设备的信号，其中，Ecdpcch1 大于Ecdpcch0 ，即将发送功率调高。
另外，在增大DPCCH的功率后，控制模块12还需要及时调整增强专用物理数据信道(E-DPDCH)的功率偏置，否则，没法真正实现增大DPCCH以保证DPCCH的性能的目的。因为跟随DPCCH的功率增大，E-DPDCH的功率偏置也相应增大，从而导致E-DPDCH的功率过好，由于外环的调控，会控制降低功率，从而使用户设备又进一步响应降功率指令而使用户设备的发射功率再度降低。
因此，在增大DPCCH的功率后，控制模块12及时调整E-DPDCH的功率偏置至第一功率偏置，该第一功率偏置为用户设备的最优功率偏置的平坦区域的任何一个值。控制E-DPDCH的功率偏置在用户设备的最优功率偏置的平坦区域，则用户设备的接收总功率相同。因此，通过这种方式，既达到增大DPCCH功率实现正常通讯的目的，也不会影响DPCCH的解调性能。
其中，针对增大DPCCH的功率的两种实现方式，当通过调整SIR target来增大DPCCH的功率时，控制模块12可以控制第一功率偏置满足： PO1 =(SIR0 /SIR1 )×(PO0 +POw ) - POw ，其中，PO1 为第一功率偏置，SIR0 为用户设备未处于软切换区时专用物理控制信道的初始信噪比目标值，PO0 为用户设备未处于软切换区时增强专用物理数据信道的初始功率偏置，SIR1 为用户设备处于软切换区时专用物理控制信道经调整后的第一信噪比目标值，POw 为用户设备未处于软切换区时，高速专用物理控制信道的功率偏置POhsdpcch 、增强专用物理控制信道的功率偏置POedpcch 、专用物理数据信道的功率偏置POdpdch 以及专用物理控制信道的功率偏置1的求和，POw = POhsdpcch +POedpcch +POdpdch +1。
因为平坦区接收总功率相同即E0 =E1 ,其中,
E0 /N0 =(SIR0 /256)×(PO0 +POhsdpcch +POedpcch +POdpdch +1)；
E1 /N0 =(SIR1 /256)×(PO1 +POhsdpcch +POedpcch +POdpdch +1),
所以：
PO1 =(SIR0 /SIR1 )×(PO0 +POhsdpcch +POedpcch +POdpdch +1)-(POhsdpcch +POedpcch +POdpdch +1)，若POm -POn 为用户设备的最优功率偏置的平坦区域，则POm ≤PO1 ≤POn 。
当通过调整发射功率来增大DPCCH的功率时，控制模块12可以控制第一功率偏置满足：PO1 =(Ecdpcch0 /Ecdpcch1 )×(PO0 +POw ) - POw ，其中，PO1 为第一功率偏置，Ecdpcch0 为用户设备未处于软切换区时专用物理控制信道的初始发射功率，PO0 为用户设备未处于软切换区时增强专用物理数据信道的初始功率偏置，Ecdpcch1 为用户设备处于软切换区时专用物理控制信道的经调整后的第一发射功率，POw 为用户设备未处于所述软切换区时，高速专用物理控制信道的功率偏置POhsdpcch 、增强专用物理控制信道的功率偏置POedpcch 、专用物理数据信道的功率偏置POdpdch 以及专用物理控制信道的功率偏置1的求和，POw =POhsdpcch +POedpcch +POdpdch +1。
因为平坦区接收总功率相同，即：E0 =E1 ，其中，
E0 =Ecdpcch0 ×(PO0 +POhsdpcch +POedpcch +POdpdch +1),
E1 =Ecdpcch1 ×(PO1 +POhsdpcch +POedpcch +POdpdch +1)，
所以：PO1 =(Ecdpcch0 /Ecdpcch1 )×(PO0 +POhsdpcch +POedpcch +POdpdch +1)- (POhsdpcch +POedpcch +POdpdch +1)，若POm -POn 为用户设备的最优功率偏置的平坦区域，则POm ≤PO1 ≤POn 。
如果功率调整是以信令形式通知到用户终端时，控制模块12可以控制第一功率偏置满足：PO1 =(1/POdpcch )×(PO0 +POw )- POw ，其中，PO1 为第一功率偏置，PO0 为用户设备未处于软切换区时增强专用物理数据信道的初始功率偏置，POdpcch 为用户设备处于所述软切换区时专用物理控制信道的功率偏置，POw 为用户设备未处于软切换区时，高速专用物理控制信道的功率偏置POhsdpcch 、增强专用物理控制信道的功率偏置POedpcch 、专用物理数据信道的功率偏置POdpdch 以及专用物理控制信道的功率偏置1的求和，POw =POhsdpcch +POedpcch +POdpdch +1。
因为平坦区接收总功率相同，即：E0 =E1 ，其中，
E0 =Ecdpcch0 ×(PO0 +POhsdpcch +POedpcch +POdpdch +1)，
E1 =Ecdpcch0 ×POdpcch ×(PO1 +POhsdpcch +POedpcch +PO dpdch +1)，
所以:PO1 =(1/POdpcch )×(PO0 +POhsdpcch +POedpcch +POdpdch +1)- (POhsdpcch +POedpcch +POdpdch +1), 若POm -POn 为用户设备的最优功率偏置的平坦区域，则POm ≤PO1 ≤POn 。
