Description

上行功率控制方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及一种上行功率控制方法及装置。
背景技术
无线通信系统中，对信号发送端进行上行功率控制，其目的是使信号接收端能够正确对信号进行解调，同时避免信号发射功率过大而对信号发送端所在小区的邻小区造成较强的干扰。长期演进(long term evolution，LTE)系统中的上行功率控制采取开环功率控制和闭环功率控制相结合的方式，开环功率控制是指根据下行路径损耗确定终端的发射功率，闭环功率控制是指通过向终端发送功率控制命令(power control commands)来调整上行发射功率。
无线信号在空中传输与在地面传输相比具有不同的特性。无线信号在空中传输时，由于较少障碍物的遮挡，信号的视距传播比在地面通信时明显增多。此种情况下，与地面通信相比，处于空中的终端发送的信号可能被更多小区所接收，并且对于这些小区来说可能接收信号强度较大，这就导致对这些小区造成较强的上行干扰。
目前无人机的应用越来越广泛，其在空中通信时会对邻区造成较强的上行干扰。针对此类型的终端，如何通过上行功率控制以降低上行干扰，是目前需要解决的问题。
发明内容

上述实施例中，由于终端根据邻区信息确定用于计算发射功率的功率控制参数，因此将终端对邻区的上行干扰因素引入了发射功率的计算过程，即，将终端对邻区的上行干扰作为考虑因素以计算发射功率，从而使得终端在使用发射功率发送信号时，可以降低对邻区的上行干扰。
一种可能的实施方式中，所述邻区信息中包括以下信息之一或任意组合：邻区的参考信号发射功率、邻区的上行干扰热噪比、邻区的上行负载、邻区的下行路径损耗预设阈值、邻区基站的高度等。
根据上述实施例，在具体实施时，可根据上述多种邻区信息确定干扰影响参数或者下行路径损耗的路径修正参数，从而使得估算出的邻区干扰较为精确，进而可以通过本申请实施例提供的上行功率控制方法更好地对邻区的上行干扰进行抑制。
一种可能的实施方式中，所述干扰影响参数或所述下行路径损耗的路径修正参数的确定过程包括：根据第一邻区的参考信号发射功率以及所述终端测量到的第一邻区参考信号接收强度，确定第一邻区到所述终端的下行路径损耗；其中，所述第一邻区为所述终端的一个邻区；根据第一邻区到所述终端的下行路径损耗，或者根据第一邻区到所述终端的下行路径损耗以及第一邻区的邻区信息，确定干扰影响参数或下行路径损耗的路径修正参数。其中，所述第一邻区为网络侧指示的，或者为所述终端从所述终端的邻区中选择的， 所述第一邻区为所述终端的邻区中受到强上行干扰的小区。
根据上述实施例，一方面，在计算所述干扰影响参数或所述下行路径损耗的路径修正参数时依据邻区到终端的下行路径损耗，由于邻区到终端的下行路径损耗能够反映邻区受到该终端的上行干扰程度，因此基于该下行路径损耗所计算得到的所述干扰影响参数或所述下行路径损耗的路径修正参数，能够较为精确地反映该终端对邻区的干扰，进而可以通过本申请实施例提供的上行功率控制方法更好地对上行干扰进行抑制。另一方面，计算邻区到终端的下行路径损耗时，所选择的邻区为终端的邻区中受到强上行干扰的小区，比如可以是受到上行干扰最强的小区，这样，以该小区到终端的下行路径损耗作为计算所述干扰影响参数或所述下行路径损耗的路径修正参数的依据，使得根据该干扰影响参数或修正参数所计算出的发射功率，可以对受干扰较强的小区的上行干扰起到抑制作用。
一种可能的实施方式中，所述干扰影响参数根据第一公式或第二公式或第三公式确定得到：
所述第一公式为：βc＝θ/PLM
所述第二公式为：

上述实施例中，将终端的工作模式区分为地面模式和空中模式，并针对目标信道或目标信号设置多个功率控制参数集合，以适配不同的工作模式。由于地面模式和空中模式的通信特性不同，相同的信号发射功率在终端处于不同工作模式时对邻区的上行干扰程度不同，因此通过上述方法可以使得基站根据终端的工作模式选择出相适配的功率控制参数集合，从而可以对终端的邻区上行干扰进行抑制。

具体实施方式
下面将结合附图，对本申请实施例进行描述。
首先，对本申请中的部分用语进行解释说明，以便于本领域技术人员理解。
(1)网络设备，可以称之为无线接入网(Radio Access Network，RAN)设备，是一种将终端接入到无线网络的设备，包括但不限于：演进型节点B(evolved Node B，eNB)、无线网络控制器(Radio Network Controller，RNC)、节点B(Node B，NB)、基站控制器(Base Station Controller，BSC)、基站收发台(Base Transceiver Station，BTS)、家庭基站(例如，Home evolved NodeB，或Home Node B，HNB)、基带单元(Base Band Unit，BBU)、无线保真(Wireless Fidelity，WIFI)接入点(Access Point，AP)，传输点(transmission and  receiver point，TRP或者transmission point，TP)、继续演进的节点B(gNB)等。
(2)终端，是一种向用户提供语音和/或数据连通性的设备，可以包括各种具有无线通信功能的手持设备、车载设备、可穿戴设备、计算设备、无人机或连接到无线调制解调器的其它处理设备，以及各种形式的用户设备(User Equipment，UE)，移动台(Mobile station，MS)，终端设备(Terminal Equipment)，传输点(transmission and receiver point，TRP或者transmission point，TP)等等。
(3)交互，本申请中的交互是指交互双方彼此向对方传递信息的过程，这里传递的信息可以相同，也可以不同。例如，交互双方为基站1和基站2，可以是基站1向基站2请求信息，基站2向基站1提供基站1请求的信息。当然，也可以基站1和基站2彼此向对方请求信息，这里请求的信息可以相同，也可以不同。
(4)“多个”是指两个或两个以上。“和/或”，描述关联对象的关联关系，表示可以存在三种关系，例如，A和/或B，可以表示：单独存在A，同时存在A和B，单独存在B这三种情况。字符“/”一般表示前后关联对象是一种“或”的关系。
图1示例性地示出了一种可能的通信场景的示意图。如图1所示，终端10为无人机，终端10处于空中，通过基站21接入到无线网络，以通过无线网络获取外网(例如因特网)的服务，或者通过无线网络与其它终端通信。基站22和基站23为与基站21相邻的节点。终端10向基站21发送信号时，由于信号传输路径上几乎没有遮挡物，基站22和基站23均接收到该信号，且接收信号强度较大，这样，基站22和基站23覆盖范围内的小区会受到较强的上行干扰。基站间可通过基站间的链路进行信息交互。其中，上述基站可替换为其他网络设备，比如RAN节点。
基于上述通信场景，本申请实施例中，针对终端对邻区造成的上行干扰进行估算，并将其引入对终端的上行功率控制过程，即，将估算出的对邻区造成的上行干扰作为对终端进行上行功率控制的依据之一，以减小对邻区的上行干扰。
可以理解的是，本申请实施例中的方案还可以应用于其他无线通信网络中，例如可应用于未来5G新无线(New Radio，NR)通信架构中。
为此，本申请实施例提供了以下三种解决方案：
方案一：终端在进行上行功率控制时，针对该终端对邻区的上行干扰进行估算，并依据估算结果来影响功率控制参数，并根据该功率控制参数进行上行功率控制；
方案二：网络为终端配置多个功率控制参数集合，网络设备根据终端对邻区的上行干扰，从配置的多个功率控制参数集合中选择一个，并将选择出的功率控制参数集合通知给终端，使终端根据该功率控制参数集合中的功率控制参数进行上行功率控制；
方案三：网络针对同一信道或同一信号配置多个功率控制参数集合，所配置的功率控制参数集合与终端的工作模式相对应，终端进行上行功率控制时，首先确定自身的工作模式，再根据自身的工作模式从多个功率控制参数集合中选择与当前工作模式对应的功率控制参数集合，并根据选择出的功率控制参数集合中的功率控制参数进行上行功率控制。
本申请实施例中所述的“邻区”是指终端所在小区的邻小区。终端的邻区通常包括多个，终端的邻区可包括：与该终端所在的小区属于同一基站覆盖范围内的小区，也可以包括与该终端所在的小区属于不同基站覆盖范围内的小区。
下面结合附图分别对上述三种方案进行描述。
方案一
方案一提供的上行功率控制流程中，终端需要估算终端对邻区的干扰，终端对邻区的干扰可通过干扰影响参数表征。干扰影响参数可依据邻区信息确定。需要说明的是，“干扰影响参数”仅为一种示例性命名，本申请实施例对该参数的命名不作限制。
在具体实施时，可以根据邻区信息以及以及根据终端自身信息和终端测量信息中的至少一个来确定邻区干扰信息，再根据邻区干扰信息确定干扰影响参数。所确定出的邻区干扰信息可包括以下部分或全部信息：邻区到终端的下行路径损耗、邻区的上行干扰热噪比(interference over thermal，IoT)、邻区的上行负载等。
其中，所述终端自身信息可包括终端的高度，或者其他能够反映终端状态、位置或通信情况等的信息。
所述终端测量信息可包括终端针对来自邻区的信号的参考信号接收功率(reference signal receiving power，RSRP)。网络侧可对终端的测量进行配置，比如可配置终端对哪些信息进行测量。本申请实施例对终端测量信息的具体类型不作限制，终端可根据网络侧的测量配置进行测量。
所述邻区信息包括一个或多个邻区的信息，其中，对于该一个或多个邻区中的一个小区来说，其邻区信息可包括以下信息中的一个或任意组合：该小区的RS发射功率、该小区的上行IoT、该小区的上行负载、该小区的下行路径损耗阈值、该小区的基站的高度等。
相邻基站间可通过基站间的链路交互邻区信息。基站可将邻区信息发送给该基站覆盖范围内的终端。对于一个终端来说，它从其服务基站接收到的邻区信息可包括该服务基站覆盖范围内的邻区的信息，也可包括其他基站覆盖范围内的邻区的信息。基站可通过专有信令或广播消息将邻区信息发送给终端。所述专有信令可以是无线资源控制(radio resource control，RRC)消息。可选地，基站可将邻区信息组织成邻区列表的形式发送给终端，该邻区列表中包括一个或多个邻区的信息，针对每个邻区分配一个索引，用于索引相应邻区的信息。
基站除了可以将邻区信息发送给终端，还可以进一步地向终端发送指示信息以指示受到强上行干扰的邻区，比如受到上行干扰最强的邻区。所指示的邻区为该基站发送给终端的邻区列表中的一个邻区。该指示信息可以通过下行控制信息(downlink control information，DCI)发送。该指示信息可以是该受到强上行干扰的邻区在邻区列表中的索引，也可以以位图(bitmap)方式进行指示，比如，向终端发送一个二进制序列，该二进制序列的比特数量与发送给该终端的邻区列表中的邻区数量相同，且一个比特位对应一个邻区，如果比特位的取值为1，则对应的邻区为受到强上行干扰的小区，比特位的取值为0，则对应的邻区未受到强上行干扰，反之亦然。
针对一个终端，基站可自行判断该终端的邻区中受到强上行干扰的邻区。作为一个例子，对于一个终端，如果基站收到该终端的一个邻区的上行负载信息(如负载指示符(overload indicatorOI))和/或高干扰指示符(high interference indicator，HII)，并且该基站在相应的资源块(resource block，RB)上对该终端的上行数据传输进行了调度，则可确定该邻区受到较强的上行干扰。作为另一个例子，对于一个终端，如果基站判断该终端的邻区(或邻区所在的基站)发送过来的上行IoT超过设定阈值，则可确定该邻区受到较强的上行干扰。
终端处于空中时，其发送的信号可能对邻区造成较强的上行干扰，需要采用本申请实施例提供的方法进行上行功率控制以减小上行干扰。为了区分终端处于空中还是处于地 面，本申请实施例定义了两种工作模式：空中模式和地面模式。空中模式是指终端处于空中时的通信模式，地面模式是指终端处于地面上时的工作模式。可选地，本申请实施例中，基站可在将邻区信息发送给终端之前，首先判断该终端的工作模式，即该终端是处于空中模式还是地面模式，如果终端处于空中模式，则通过专有信令将邻区信息发送给该终端。当然，终端的工作模式也可以不限于上述两种，比如可以针对空中模式进一步根据不同的高度范围进行细分。终端的工作模式可由基站判断得到，也可由终端在确定工作模式后将其上报给基站。
其中，无论是基站还是终端均可根据以下信息中的一种或多种组合，判断终端的工作模式：终端自身信息、终端测量信息、邻区信息。其中，所述终端自身信息可包括终端的高度，或者其他能够反映终端状态、位置或通信情况等的信息；所述终端测量信息以及邻区信息包含的内容同前所述。
在根据终端自身信息判断终端的工作模式的一个例子中，如果终端所处的高度超过设定阈值(终端所处的高度可通过位置定位获得)，则判断该终端处于空中模式，否则判断该终端处于地面模式。
在根据终端测量信息判断终端的工作模式的一个例子中，如果终端与邻区之间的下行路径损耗小于设定阈值，则可判断该终端处于空中模式，否则判断该终端处于地面模式，其中，终端与邻区之间的下行路径损耗可根据邻区信息和终端测量信息计算得到，比如，一个小区到终端的下行路径损耗等于该小区的RS发射功率减去该终端测量到的该小区的RSRP。在根据终端测量信息判断终端的工作模式的另一个例子中，如果终端测量到有邻区的RSRP超过设定阈值，且邻区RSRP超过设定阈值的邻区数量达到预设的门限值，则可判断该终端处于空中模式，否则判断该终端处于地面模式。
在根据终端自身信息以及终端测量信息判断终端工作模式的一个例子中，如果终端的高度超过设定阈值，并且该终端与邻区间的下行路径损耗低于设定阈值，则判断该终端处于空中模式，否则判断该终端处于地面模式，其中，终端与邻区之间的下行路径损耗可根据邻区信息和终端测量信息计算得到。
在另外的例子中，基站也可以根据终端的类型，确定是否将邻区信息发送给终端。具体地，如果基站判断该终端为无人机类型的终端，则将邻区信息发送给该终端。
参见图2，本申请实施例方案一提供的上行功率控制流程示意图。如图2所示，终端进行上行功率控制时，可执行如下流程：
S201：终端确定功率控制参数，所述功率控制参数中包括干扰影响参数；其中，所述干扰影响参数可根据该终端的邻区信息或邻区干扰信息确定得到。
其中，功率控制参数作为发射功率计算公式的输入参数，用来计算发射功率。本申请实施例中，干扰影响参数作为功率控制参数参与发射功率的计算。功率控制参数除了包含干扰影响参数以外，还可包括其他参数，比如包括网络侧配置的参数。
干扰影响参数可以是邻区信息或邻区干扰信息的函数。其中，邻区信息可通过基站发送给终端。邻区信息的发送方式以及邻区信息所包含的内容，可参见前述描述，在此不再重复。
在一个例子中，终端可根据邻区信息和终端测量信息确定出终端与邻区间的下行路径损耗，并可进一步确定出邻区上行IoT、邻区上行负载等，并根据所确定出的这些信息确定干扰影响参数。
下面以终端所在的小区为小区c，且小区M为小区c的一个邻区为例，说明干扰影响参数的确定方法。
在干扰影响参数的确定方法一个例子中，基站可根据小区M的RS发射功率以及该终端测量到的小区M的RSRP，确定小区M到该终端的下行路径损耗，并根据该下行路径损耗确定干扰影响参数。具体地，可根据以下公式确定干扰影响参数βc：
βc＝θ/PLM……………………………………………………[1]
其中：
PLM为小区M到终端的下行路损损耗，PLM＝referenceSignalPowerM-RSRPM，其中referenceSignalPowerM表示小区M的RS发射功率，可从基站发送给终端的邻区信息中可获得(该邻区信息中包含小区M的RS发射功率)，RSRPM表示终端测量到的小区M的RSRP；
θ可为设定值，具体地，θ可由高层配置。高层可通过RRC信令配置θ给终端，或者配置用于确定θ的参数，由终端根据该参数计算得到θ的取值。本例子中，θ为非正值，如果终端处于空中模式，则θ为负值，如果终端处于地面模式，则θ为0。
在干扰影响参数的确定方法的另一个例子中，基站可以根据更多的因素确定干扰影响参数，比如，可根据小区M的RS发射功率以及该终端测量到的小区M的RSRP，确定小区M到该终端的下行路径损耗，再根据该下行路径损耗、小区M的上行负载、小区M的上行IoT等确定干扰影响参数。具体地，可根据以下公式确定干扰影响参数βc：
Figure PCTCN2017095035-appb-000005
其中，PLM表示小区M到该终端的下行路径损耗，IoTM表示小区M的上行干扰热噪比，LoadM表示小区M的上行负载。x、y、z为设定值，可以预先设定或者由高层配置，可取值为大于等于0。θ的取值以及含义同前所述。
在干扰影响参数的确定方法的另一个例子中，基站可以根据小区M的RS发射功率以及该终端测量到的小区M的RSRP，确定小区M到该终端的下行路径损耗，再根据该下行路径损耗、小区M的上行负载确定干扰影响参数。具体地，可根据以下公式确定干扰影响参数βc：
Figure PCTCN2017095035-appb-000006
上述干扰影响参数确定方法中涉及的小区M作为参考邻区用于上行干扰估算，小区M可以是该终端的邻区中的任意一个邻区，可以由终端选取，也可以是基站指示的。如前所述，基站可以向终端发送指示信息以指示受到强上行干扰的邻区。
为了更合理地对上行干扰进行估算，以便更好地减小邻区上行干扰，作为用于上行干扰估算的参考邻区，小区M可以是终端的邻区中符合一定条件的小区。比如，可以是受到强上行干扰的小区(比如受上行干扰最强的小区)，或者是路径损耗小的小区(比如路径损耗最小的小区)，或者是上行IoT大的小区(比如上行IoT最大的小区)，或者是上行负载大的小区(比如上行负载最大的小区)。还可以结合各邻区的信息进行综合考虑来选取参考小区，比如选取下行路径损耗小、上行负载大以及上行IoT大的小区。以下表达式示出了一种选取参考小区的方法：
Figure PCTCN2017095035-appb-000007
其中，x、y、z为设定值，可以预先设定或者由高层配置，可取值为大于等于0。max()表示取最大值运算，arg表示使
Figure PCTCN2017095035-appb-000008
达到最大值时变量m的取值。
S202：终端根据确定出的功率控制参数确定发射功率。
该步骤中，终端可将S202中计算出的干扰影响参数作为功率控制参数之一，并可结合该终端所在的小区到该终端的下行路径损耗，或者进一步结合网络侧配置的参数，确定发射功率。
以下分别以对物理上行链路控制信道(Physical Uplink Control Channel，PUCCH)、物理上行共享信道(physical uplink shared channel，PUSCH)、信道探测参考信号(sounding reference signal，SRS)、物理随机接入信道(physical random access channel，PRACH)进行上行功率控制为例进行描述。其中，约定小区c为终端所在的小区。

需要说明的是，图3中各步骤的时序仅为一个示例，其中，S301～S302的过程相对于S303至S305的过程相对独立。比如，终端需要进行上行功率控制时，即可按照S303至S304执行上行功率控制流程，不一定每次执行上行功率控制时，都包含S301～S302的过程。
通过以上实施例可以看出，由于根据邻区信息，或者进一步结合终端自身信息和/或终端测量信息确定干扰影响参数，并将干扰影响参数作为功率控制参数之一，从而在上行功率控制时将邻区干扰因素引入了上行功控中，从而可以对上行功率控制进行优化，以减少终端对邻区的上行干扰。
参见图4，为本申请实施例方案一提供的另一上行功率控制流程示意图。
与图2所示流程相同的是，本申请实施例提供的上行功率控制流程中，需要估算终端对邻区的干扰，终端对邻区的干扰可通过下行路径损耗的路径修正参数表征。需要说明的是，“下行路径损耗的路径修正参数”仅为一种示例性命名，本申请实施例对该参数的命名不作限制。
下行路径损耗的路径修正参数可依据邻区信息或邻区干扰信息确定，邻区干扰信息可根据邻区信息以及根据终端自身信息和终端测量信息中的至少一个来确定。所确定出的邻区干扰信息可包括以下部分或全部信息：邻区到终端的下行路径损耗、邻区的上行干扰热噪比(interference over thermal，IoT)、邻区的上行负载等。
其中，邻区信息的内容以及交互方式，以及基站将邻区信息发送给终端的方式，与前述实施例相同。终端自身信息和终端测量信息的定义与前述实施例相同。
与前述实施例类似，基站除了可以将邻区信息发送给终端，还可以进一步地向终端发送指示信息以指示受到强上行干扰的邻区，比如受到上行干扰最强的邻区。
与前述实施例类似，基站可在将邻区信息发送给终端之前，首先判断该终端的工作模式，即该终端是处于空中模式还是地面模式，如果终端处于空中模式，则通过专有信令将邻区信息发送给该终端。在另外的例子中，基站也可以根据终端的类型，确定是否将邻区信息发送给终端。具体地，如果基站判断该终端为无人机类型的终端，则将邻区信息发送给该终端。
如图4所示，终端进行上行功率控制时，可执行如下流程：
S401：终端确定功率控制参数，所述功率控制参数中包括下行路径损耗的路径修正参数；其中，所述下行路径损耗的路径修正参数可根据该终端的邻区信息或邻区干扰信息确定得到。该修正参数用于对该终端所在小区到该终端的下行路径损耗进行修正，修正后的下行路径损耗可作为输入参数参与发射功率的计算。比如，可将该修正参数与终端所在小区到该终端的下行路径损耗相乘的方式，对该路径损耗进行修正。当然，也可基于该修正参数并采用其他运算法对终端所在小区到该终端的下行路径损耗进行修正。
其中，功率控制参数作为发射功率计算公式的输入参数，用来计算发射功率。本申请 实施例中，下行路径损耗的路径修正参数作为功率控制参数的一种参与发射功率的计算。功率控制参数除了包含上述修正参数以外，还可包括其他参数，比如包括网络侧配置的参数。
下行路径损耗的路径修正参数可以是邻区信息或邻区干扰信息的函数，而所述邻区干扰信息可根据邻区信息以及根据终端自身信息和终端测量信息中的至少一种确定得到，所确定出的邻区干扰信息可包括以下信息中的一种或多种的组合：终端与邻区间的下行路径损耗(该下行路径损耗可邻区的RS发射功率以及终端测量到的邻区RSRP得到)、邻区上行IoT、邻区上行负载等。
在一个例子中，终端可根据邻区信息和终端测量信息确定出终端与邻区间的下行路径损耗，并可进一步确定出邻区上行IoT、邻区上行负载等，并根据所确定出的这些信息确定下行路径损耗的路径修正参数。
下面以终端所在的小区为小区c、且小区M为小区c的一个邻区为例，说明下行路径损耗的路径修正参数的确定方法。
在所述修正参数的确定方法一个例子中，基站可根据小区M的RS发射功率以及该终端测量到的小区M的RSRP，确定小区M到该终端的下行路径损耗，并根据该下行路径损耗确定修正参数。具体地，可根据以下公式确定修正参数αc：
αc＝α-γ/PLM……………………………………………[12]
其中，α为可由高层配置，其取值可与现有LTE系统的功率控制方案中高层配置的相应参数取值相同；γ由高层配置，比如可通过RRC消息进行配置，其取值可以大于0。PLM为小区M到终端的下行路径损耗，PLM＝referenceSignalPowerM-RSRPM，其中referenceSignalPowerM表示小区M的RS发射功率，可从基站发送给终端的邻区信息中可获得(该邻区信息中包含小区M的RS发射功率)，RSRPM表示终端测量到的小区M的RSRP。
在修正参数的确定方法的另一个例子中，基站可以根据更多的因素确定修正参数，比如，可根据小区M的RS发射功率以及该终端测量到的小区M的RSRP确定该小区M到该终端的下行路径损耗，再根据该下行路径损耗、小区M的邻区信息(比如小区M的上行负载、小区M的上行IoT等)确定修正参数。具体地，可根据以下公式确定修正参数αc：
Figure PCTCN2017095035-appb-000016
其中，PLM表示小区M到终端的下行路径损耗，IoTM表示小区M的上行干扰热噪比，LoadM表示小区M的上行负载。x、y、z为设定值，可以预先设定或者由高层配置，可取值为大于等于0。α的取值以及含义同前所述。
在修正参数的确定方法的另一个例子中，基站可以根据小区M的RS发射功率以及该终端测量到的小区M的RSRP，确定小区M到该终端的下行路径损耗，再根据该下行路径损耗、小区M的上行负载确定干扰影响参数。具体地，可根据以下公式确定干扰影响参数αc：
Figure PCTCN2017095035-appb-000017
上述下行路径损耗的路径修正参数确定方法中涉及的小区M作为参考邻区用于上行干扰估算，小区M可以是该终端的邻区中的任意一个邻区，可以由终端选取，也可以是基站 指示的。如前所述，基站可以向终端发送指示信息以指示受到强上行干扰的邻区。
为了更合理地对上行干扰进行估算，以便更好地减小邻区上行干扰，作为用于上行干扰估算的参考邻区，小区M可以是终端的邻区中符合一定条件的小区。比如，可以是受到强上行干扰的小区(比如受上行干扰最强的小区)，或者是路径损耗小的小区(比如路径损耗最小的小区)，或者是上行IoT大的小区(比如上行IoT最大的小区)，或者是上行负载大的小区(比如上行负载最大的小区)。还可以结合各邻区的信息进行综合考虑来选取参考小区，比如选取下行路径损耗小、上行负载大以及上行IoT大的小区。比如可采用前述公式(4)选取参考小区。
S402：终端根据确定出的功率控制参数确定发射功率。
该步骤中，终端可将S401中计算出的修正参数作为功率控制参数之一，使用该修正参数修正终端下行路径损耗，并可进一步结合其他功率控制参数，进行上行功率控制。
以下分别以对PUSCH、SRS进行上行功率控制为例进行描述。其中，约定小区c为终端所在的小区。
在对该终端的PUSCH进行上行功率控制时，如果该终端没有同时传PUSCH和PUCCH，则该终端的PUSCH的发射功率可根据以下公式确定(单位为dBm)：
Figure PCTCN2017095035-appb-000018
其中，PCMAX,c(i)是小区c中每个子载波的最大发射功率；MPUSCH,c(i)是PUSCH一个子帧内占用的RB数；PO_PUSCH,c(j)是由高层配置的两个参数求和得到的；PLc是终端计算的下行路径损耗，下行路径损耗等于小区c的RS发射功率减去终端测量到的小区c的RSRP；
Figure PCTCN2017095035-appb-000019
其中KS由高层配置；fc(i)是一个与高层配置和δPUSCH,c有关的值，其中δPUSCH,c是与PDCCH/EPDCCH指示的TPC命令有关的值。αc(j)是通过本申请上述实施例提供的方法计算得到的下行路径损耗的路径修正参数。
如果终端同时传PUSCH和PUCCH，则该终端的PUSCH的发射功率可根据如下公式确定(单位为dBm)：
Figure PCTCN2017095035-appb-000020
其中，
Figure PCTCN2017095035-appb-000021
是PUCCH的发射功率，其余参数可参见公式(15)中的参数说明。
如果终端不发PUSCH，但收到了DCI格式3/3A(DCI format 3/3A)的TPC命令，则该终端假定PUSCH的发射功率为(单位为dBm)：
PPUSCH,c(i)＝min{PCMAX,c(i),PO_PUSCH,c(1)+αc(j)·PLc+fc(i)}…………………[17]
公式(17)中的部分参数的含义与公式(15)中相应参数的含义相同，在此不再重复说明。αc(j)是通过本申请上述实施例提供的方法计算得到的下行路径损耗的路径修正参数。
在对该终端的SRS的上行功率进行控制时，可根据以下公式确定SRS的发射功率(单位为dBm)：
PSRS,c(i)＝min{PCMAX,c(i),PSRS_OFFSET,c(m)+10log10(MSRS,c)+PO_PUSCH,c(j)+αc(j)·PLc+fc(i)}…………[18]
其中，PSRS_OFFSET,c(m)是高层配置的半静态参数；MSRS,c是SRS在一个子帧内所占RB数；fc(i)是PUSCH的功率控制调节器(power control adjustment)；PO_PUSCH,c(j)同PUSCH功率控制公式中的定义。αc(j)是通过本申请上述实施例提供的方法计算得到的下行路径损耗的路径修正参数。
图5示出了根据图4所示的上行功率控制流程的一种信令交互流程示意图。该例子中约定：小区1为终端所在的小区，小区2～小区n(n为大于2的整数)为小区1的邻区，下行路径损耗的路径修正参数根据上述公式(12)确定。如图所示，在S501中，小区2～小区n所在的基站分别将小区2～小区n的信息(其中包括RS发射功率)发送给小区1所在的基站；在S502中，基站通过广播消息将小区2～小区n的信息(其中包括RS发射功率)发送给终端；在S503中，基站通过RRC消息将计算下行路径损耗的路径修正参数所需的参数配置给终端；在S504中，终端对小区2～小区n进行RSRP测量，根据测量结果，选取其中最小的下行路径损耗，并根据公式(12)计算下行路径损耗的路径修正参数；在S505中，终端根S504中计算得到的修正参数对小区1到该终端的下行路径损耗进行修正，并根据修正后的路径损耗进行上行功率控制。
需要说明的是，图5中各步骤的时序仅为一个示例，其中，S501～S502的过程相对于S503的过程以及相对于至S504～S505的过程相对独立。比如，终端需要进行上行功率控制时，即可按照S504至S505执行上行功率控制流程，不一定每次执行上行功率控制时，都包含S501～S502的过程或者包括S503的过程。
通过以上实施例可以看出，由于根据邻区信息，或者进一步结合终端自身信息和/或终端测量信息确定下行路径损耗的路径修正参数，并使用该修正参数对路径损耗进行修正，使用修正后的路径损耗进行上行功率控制，从而在上行功率控制时将邻区干扰因素引入了上行功控中，从而可以对上行功率控制进行优化，以减少终端对邻区的上行干扰。
方案二
方案二提供的上行功率控制流程中，需要估算终端对邻区的干扰。估算终端对邻区的干扰可依据邻区信息，进一步地在此基础上还可依据终端测量信息和终端自身信息中的至少一种。终端测量信息由终端上报给基站。其中，邻区信息的内容以及交互方式，与前述实施例相同。终端测量信息和终端自身信息的定义与前述实施例相同。基站可将邻区信息组织成邻区列表的形式，该邻区列表中包括一个或多个邻区的信息，针对每个邻区分配一个索引，用于索引相应邻区的信息。
在方案二提供的实施例中，可针对同一信道或同一信号，配置多个功率控制参数集合。具体来说，可针对进行上行功率控制的信道配置多个功率控制参数集合，比如这样的信道可包括PUCCH、PUSCH、PRACH等信道中的一个或多个。可针对进行上行功率控制的信号配置多个功率控制参数集合，这样的信号可包括上行参考信号，比如SRS等。
由于不同信道或不同信号的功率控制算法可能不同，因此不同信道或不同信号对应的功率控制参数集合中所包括的功率控制参数的类型可能不同。对于同一信道或同一信号所对应的多个功率控制参数集合，其中包含相同类型的功率控制参数，但功率控制参数的取值不同，从而针对同一信道或同一信号，使用不同的功率控制参数集合进行功率控制可以实现不同的功率控制效果。在实际应用中，可针对不同的场景(比如终端处于空中模式还是地面模式，或者终端对邻区造成的上行干扰程度)使用相应的功率控制参数集合进行上行功率控制。
举例来说，对于PUCCH，配置2个功率控制参数集合(集合1和集合2)，集合1和集合2中均包括PUCCH的功率控制参数PO_PUCCH，但集合1和集合2中该参数的取值不同。更具体地，集合1适合于终端处于空中模式或对邻区造成较强干扰时使用，集合2适合于终端处于地面模式或对邻区造成的干扰较小时使用。
再比如，对于PUSCH，配置2个功率控制参数集合(集合1和集合2)，集合1和集合2中均包括PUSCH的功率控制参数PO_PUSCH,c(j)、αc(j)，但集合1和集合2中这两个参数中的至少一个参数的取值不同。
再比如，对于SRS，配置2个功率控制参数集合(集合1和集合2)，集合1和集合2中均包括SRS的功率控制参数PO_PUSCH,c(j)、αc(j)，但集合1和集合2中这两个参数中的至少一个参数的取值不同。
再比如，对于PRACH，配置2个功率控制参数集合(集合1和集合2)，集合1和集合2中均包括PRACH的功率控制参数PREAMBLE_RECEIVED_TARGET_POWER，但集合1和集合2中该参数的取值不同。
以上虽然是以针对同一信道或同一信号配置2个功率控制参数集合为例描述的，但应理解，针对同一信道或同一信号可配置2个以上的功率控制参数集合。
针对同一信道或同一信号所配置的多个功率控制参数集合，可以预先约定。可选地，可以通过基站将针对同一信道或同一信号所配置的多个功率控制参数集合发送给终端。在通过基站发送给终端的例子中，基站可通过专有信令或广播消息将功率控制参数集合配置给终端，比如，基站可通过现有的RRC消息或新定义的RRC消息，比如RRC连接重配置消息，将功率控制参数集合发送给终端，也可通过新定义的系统信息块(system information block，SIB)消息将功率控制参数集合发送给终端。
本申请实施例中，考虑到不同终端的类型可能不同，基站也可以根据终端的类型，确定是否将多个功率控制参数集合发送给终端。具体地，如果基站判断该终端为无人机类型的终端，则将多个功率控制参数集合发送给该终端。
参见图6，为本申请实施例方案二提供的上行功率控制流程。如图6所示，基站需要对终端的某个信道或信号(以下称为目标信道或目标信号)进行上行功率控制时，针对需要进行上行功率控制的终端可执行如下流程：
S601：基站获取该终端的邻区信息，进一步地还可获取该终端的测量信息和该终端的自身信息中的至少一种。
S602：基站根据该终端的邻区信息，或者进一步根据该终端的测量信息和该终端的自身信息中的至少一种，针对目标信道或目标信号，从所述目标信道或目标信号对应的多个功率控制参数集合中选择一个功率控制参数集合。
该步骤中，基站可根据该终端的邻区信息，或者进一步根据该终端的测量信息和该终端的自身信息中的至少一种，确定该终端对其邻区造成的上行干扰，并据此进行功率控制参数集合的选择。
比如，针对PUCCH配置了2个功率控制参数集合(集合1和集合2)，集合1和集合2中均包括功率控制参数PO_PUCCH，但集合1中该参数的取值小于集合2中该参数的取值，PUCCH的功率控制采用前述公式(5)描述的方式。在针对某个终端的PUCCH进行上行功率控制时，若基站根据该终端的邻区信息和该终端上报的测量信息，判断该终端对邻区造成比较大的干扰，则从PUCCH对应的集合1和集合2中选择集合1。
本申请实施例中，针对需要进行上行功率控制的终端，根据该终端的邻区信息，或者进一步根据该终端的测量信息和该终端的自身信息中的至少一种，确定该终端对其邻区造成的上行干扰的方法，可以采用多种方法，本申请实施例对此不作限制。作为一个例子，如果该终端基于测量到的邻区RSRP所计算出的该邻区到该终端的下行路径损耗低于设定阈值，且该邻区的上行IoT高于设定阈值，则可确定该终端对其邻区造成较大干扰。作为另一个例子，可根据该终端的邻区信息以及该终端的测量信息计算上行干扰度量参数，如果该参数取值大于设定阈值，则可确定该终端对其邻区造成较大干扰，其中，该终端对邻区M的上行干扰度量参数的计算公式的一个例子是：
Figure PCTCN2017095035-appb-000022
其中，λM表示终端对邻区M造成的上行干扰的度量值；PLM表示邻区M到该终端的下行路径损耗，PLM＝referenceSignalPowerM-RSRPM，其中referenceSignalPowerM表示邻区M的RS发射功率，RSRPM表示终端测量到的邻区M的RSRP；IoTm表示邻区M的上行干扰热噪比；Loadm表示邻区M的上行负载。x、y、z为设定值，可以预先设定或者由高层配置，可取值为大于等于0。
S603：基站将选择出的功率控制参数集合通知给该终端，使得该终端可根据该通知，使用相应功率控制参数集合中的功率控制参数确定所述目标信道或目标信号的发射功率。
在S603的一个例子中，基站可将选择出的功率控制参数集合中所包含的功率控制参数发送给终端。
为了节省信令开销，在S603的另一例子中，终端上针对同一信道或同一信号已经配置有多个功率控制参数集合，比如可通过预先约定的方式进行配置，也可通过基站发送的方式进行配置。这样，在S603中，基站可通过指示信息将选择出的功率控制参数集合通知给终端。具体地，基站可通过DCI或RRC消息将上述指示信息发送给终端。
上述指示信息可以是功率控制参数集合的标识或索引。举例来说，如果针对PUSCH配置了2个功率控制参数集合(集合1和集合2)，在针对PUSCH进行上行功率控制时，基站可使用1比特信息通知终端使用集合1还是使用集合2，比如当该比特取值为0时，指示终端使用集合1，当该比特取值为1时，指示终端使用集合2。
上述指示信息也可以是变更指示，用于指示终端更换功率控制参数集合，或者说指示终端使用不同于当前使用的功率控制参数集合。举例来说，如果针对PUSCH配置了2个功率控制参数集合(集合1和集合2)，在针对PUSCH进行上行功率控制时，基站可使用1比特信息作为变更指示，当变更指示取值为0时或者基站未发送变更指示时，表示保持当前使用的功率控制参数集合不变，当变更指示取值为1时，表示使用不同于当前使用的功率控制参数集合。比如，终端当前使用集合1，若终端接收到变更指示(取值为1)，则使用集合2，若终端未接收到变更指示或接收到的变更指示取值为0，则仍使用集合1。
上述流程中，根据所采用的上行功率控制算法的不同，功率控制参数集合中包含的参数也可能不同，本申请实施例对所使用的上行功率控制算法不做限制。作为一个例子，S803中可采用LTE协议中定义的上行功率控制算法进行发射功率设置。本申请实施例对此不做限制。
图7示出了根据图6所示的上行功率控制流程的一种信令交互流程示意图。如图所示，在S701中，基站通过RRC连接重配置消息将PUCCH对应的2个功率控制参数集合(集合1 和集合2)发送给终端；在S702中，终端向基站上报测量报告，该测量报告中包括终端测量到的邻区RSRP；在S703中，基站根据该终端的邻区信息以及该终端上报的测量报告，判断该终端对邻区的上行干扰，由于不同的上行干扰程度对应于终端的不同工作模式(比如处于空中模式时对邻区造成的干扰相较于处于地面模式时更大)，因此该步骤中，可根据该终端对邻区造成的上行干扰确定该终端的工作模式，基站根据该终端对邻区的上行干扰或根据该终端的工作模式从集合1和集合2中为该终端选择一个集合；在S704中，基站通过DCI向终端发送通知，其中包括1比特的指示信息，以指示终端是使用集合1还是使用集合2确定PUCCH的发射功率。
需要说明的是，图7中各步骤的时序仅为一个示例，其中，S701的过程、S702的过程，以及S703～S704的过程各自独立。比如，需要对终端进行上行功率控制时，即可按照S703至S704执行上行功率控制流程，不一定每次执行上行功率控制时，都包含S701和S702的过程。
通过以上描述可以看出，由于针对同一信道或同一信号配置多个功率控制参数集合，基站根据邻区信息以及根据终端测量信息和终端自身信息中的至少一种，从同一信道或同一信号对应的多个功率控制参数集合选取一个功率控制参数集合，并将选择出的功率控制参数集合通知给终端，以使终端根据该功率控制参数集合设置发射功率，从而可以针对不同的场景(比如终端对邻区造成的干扰较强或较弱)使用不同的功率控制参数进行上行功率控制。
方案三
方案三提供的上行功率控制流程中，终端需要判断其所处的工作模式，其中，判断终端所处的工作模式的方法可参见本申请实施例方案一中的描述。
如前述实施例所述，终端工作模式可根据终端自身信息、终端的邻区信息、终端的测量信息中的一种或多种组合进行判断。其中，邻区信息的内容以及交互方式，与前述实施例相同。终端测量信息和终端自身信息的定义与前述实施例相同。所述邻区信息可组织成邻区列表的形式，该邻区列表中包括一个或多个邻区的信息，针对每个邻区分配一个索引，用于索引相应邻区的信息。
在方案三提供的实施例中，可针对同一信道或同一信号，配置多个功率控制参数集合，不同的功率控制参数集合可对应不同的终端工作模式(比如空中模式或地面模式)。与此相关的定义和配置方法，可参见方案二中的相应描述，在此不再重复。
针对同一信道或同一信号所配置的多个功率控制参数集合，可以预先约定，也可以通过基站将针对同一信道或同一信号所配置的多个功率控制参数集合发送给终端。在通过基站发送给终端的例子中，基站可通过专有信令(比如RRC消息)或广播消息将功率控制参数集合配置给终端。
本申请实施例中，考虑到不同终端的类型可能不同，基站也可以根据终端的类型，确定是否将多个功率控制参数集合发送给终端。具体地，如果基站判断该终端为无人机类型的终端，则将多个功率控制参数集合发送给该终端。
参见图8，为本申请实施例方案三提供的上行功率控制流程示意图，如图2所示，终端进行上行功率控制时，可执行如下流程：
S801：终端根据所述终端所处的高度、所述终端的邻区信息、所述终端的测量信息中的至少一种，确定所述终端的工作模式。
其中，确定终端的工作模式的方法，可参见前述实施例的描述，在此不再重复。
S802：终端根据所述终端的工作模式，从目标信道或目标信号对应的多个功率控制参数集合中选择功率控制参数集合。
该步骤中，由于同一信道或同一信号对应的多个功率控制参数集合，可对应于不同的工作模式，因此可针对同一信道或同一信号所对应的多个功率控制参数集合中，根据终端的工作模式从中选择一个与终端当前的工作模式匹配的功率控制参数集合，从而可以更好地降低终端对邻区的上行干扰。
S803：终端根据选择出的功率控制参数集合，确定所述目前信道或目标信号的发射功率。
上述流程中，根据所采用的上行功率控制算法的不同，功率控制参数集合中包含的参数也可能不同，本申请实施例对所使用的上行功率控制算法不做限制。作为一个例子，S803中可采用LTE协议中定义的上行功率控制算法进行发射功率设置。本申请实施例对此不做限制。
通过以上描述可以看出，由于针对同一信道或同一信号配置多个功率控制参数集合，不同的集合与不同的工作模式相对应，即不同的集合适用于不同的工作模式，终端可在确定出工作模式后选取适合的功率控制参数集合进行上行功率控制。
上述主要从终端和网络设备交互的角度对本申请实施例提供的方案进行了介绍。可以理解的是，终端和网络设备为了实现上述功能，其包含了执行各个功能相应的硬件结构和/或软件模块。结合本申请中所公开的实施例描述的各示例的单元(器、器件)及算法步骤，本申请实施例能够以硬件或硬件和计算机软件的结合形式来实现。某个功能究竟以硬件还是计算机软件驱动硬件的方式来执行，取决于技术方案的特定应用和设计约束条件。本领域技术人员可以对每个特定的应用来使用不同的方法来实现所描述的功能，但是这种实现不应认为超出本申请实施例的技术方案的范围。
