Description

一种上行功率控制方法及基站
本申请要求在2017年2月22日提交中华人民共和国知识产权局、申请号为201710096611.4，发明名称为“一种上行功率控制方法及基站”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及通信技术领域，尤其涉及一种上行功率控制方法及基站。
背景技术
LTE(Long Term Evolution，长期演进)***中的功率控制根据链路方向分为下行功率控制和上行功率控制两种，其中，下行功率控制是在频率和时间上采用恒定的发射功率，即下行功率控制是以每个RE(Resource Element，资源粒子)为单位的功率分配策略，而上行功率控制使得对于相同的MCS(Modulation And Coding Scheme，调制与编码策略)，不同用户到达基站的PSD(PowerSpectral Density，功率谱密度)，亦即单位带宽上的功率大致相等。
对于LTE***而言，下行采用OFDMA(Orthogonal Frequency Division Multiple Access，正交频分多址)技术，因此不同用户间的下行信号相互正交，不存在CDMA(Code Division Multiple Access，码分多址)***的远近效应，同时为了不影响下行CQI(Channel Quality Indicator，信道质量指示)的测量和下行调度的准确性，下行同小区内不同用户之间的上行数据，设计成相互正交。基站为不同的用户分配不同的发送带宽和调制编码机制MCS，使得不同条件下的用户获得相应不同的上行发射速率。因此同CDMA***相比，LTE***的小区内上行干扰的管理就相对容易得多。
LTE***采用的以OFDM为多址接入方式而构建的蜂窝移动通信***中，可以做到频率复用因子为1，即整个***覆盖范围内的所有小区使用相同的频带为本小区的用户提供服务，这样可以大大提高小区中心用户的SINR (Signal to Interference plus Noise Ratio，信号干扰噪声比)，从而可以提供更高的数据速率和更好的服务质量。而对于小区边缘的用户，由于相邻小区占用同样载波资源的用户对其干扰比较大，加之本身距离基站较远，其SINR相对就较小，导致虽然整个小区的吞吐量较高、但小区边缘用户服务质量较差、吞吐量较低的情况。
为了解决这个LTE***在小区边缘干扰严重的问题，3GPP提出了多种解决方案，包括干扰随机化、干扰删除以及干扰协调技术。其中干扰随机化利用干扰的统计特性对干扰进行抑制，误差较大；干扰删除技术可以显著改善小区边缘的***性能，获得较高的频谱效率，但是对于带宽较小的业务(如VoIP(Voice over Internet Protocol，网络电话))则不太适用，在OFDMA***中实现也比较复杂，后续对它的研究不多；干扰协调/避免则是目前研究的一项热门技术，其实现简单，可以应用于各种带宽的业务，并且对于干扰抑制有很好的效果。
LTE***的干扰协调技术的核心思想在于采用频率复用技术，使得相邻小区之间的干扰信号源的距离尽可能远，从而抑制相邻小区的干扰，达到改善传输质量，提高吞吐量的效果。除此之外，为了使得小区间能更好的互联互通，3GPP协议规定了基站间可以通过X2接口的建立，实现基站间小区信息的交互，其中X2接口的负载指示功能使得基站间传递***的OI(overload indicator，过载指示)和HII(high interference indicator，高干扰指示)，从而实现小区间的干扰协调。
目前基于OI指示进行干扰协调的常用的手段是基站收到邻区的干扰指示后，只对使用过受干扰的资源块子集的用户实施功率控制策略，这样容易产生误调，因为用户实时调度的资源位置是动态变化的；或者只对边缘用户进行功率控制策略；或者是基站收到干扰过载指示时，根据干扰过载指示，调整小区中心和/或小区边缘用户的Po_UE_PUSCH(j)(半静态基准点，即为上行期望接收功率)等等，这些方法均没有确认真正引起干扰的用户是哪些，这样容易出现由于用户调度资源块的不可确定性或者并没有真正引起干扰的 边缘用户都被误判为干扰源用户而被进行功率降低操作；这使得非干扰源用户性能降低，却对降低小区间干扰没有什么改善。
综上所述，现有技术对终端的上行功率控制方法存在功率控制不准确，不能有效控制邻区干扰现象。

具体实施方式
为了使本发明的目的、技术方案和优点更加清楚，下面将结合附图对本发明作进一步地详细描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其它实施例，都属于本发明保护的范围。
本申请实施例可以适用于4G(***移动通信***)演进***，如LTE(Long Term Evolution，长期演进)***，或者还可以为5G(第五代移动通信***)***，如采用新型无线接入技术(new radio access technology，New RAT)的接入网；CRAN(Cloud Radio Access Network，云无线接入网)等通信***。以下，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)、终端，又称之为用户设备(User Equipment，UE)，是一种向用户提供语音和/或数据连通性的设备，例如，具有无线连接功能的手持式设备、车载设备等。常见的终端例如包括：手机、平板电脑、笔记本电脑、掌上电脑、移动互联网设备(mobile internet device，MID)、可穿戴设备，例如智能手表、智能手环、计步器等。

下面结合说明书附图对本发明实施例作进一步详细描述。
如图1所示，本发明实施例提供的上行功率控制方法，该方法执行主体为基站，包括：
步骤101、基站确定所述基站下终端的干扰邻区集合，所述干扰邻区集合 用于表示受所述终端干扰的邻区。
步骤102、基站根据所述干扰邻区集合中每个邻区的受干扰类型，确定所述终端的功控指示类型，所述每个邻区的受干扰类型用于指示每个邻区的受干扰程度。
步骤103、基站根据确定的功控指示类型，控制所述终端的上行功率。
上述步骤101中，基站确定该基站下的每个终端的干扰邻区集合，即对于该基站下的每个终端，分别对应一个干扰邻区集合，干扰邻区集合用于表示受每个终端干扰的邻区。
举例来说，参考图2，为本发明实施例提供的小区蜂窝结构示意图，其中，以基站Cell0(也称为小区Cell0)为例进行说明，如图2所示，假设基站Cell0下有终端UE1、UE2、UE3、UE4，则基站Cell0可通过收集基站内终端UE1～UE4的测量信息，如下：
UE1：(Cell5，-105dBm)、(Cell6，-98dBm)；
UE2：(Cell2，-95dBm)；
UE3：(Cell4，-90dBm)；
UE4：(Cell1，-98dBm)、(Cell6，-99dBm)。
从而，基站Cell0可以分别获得每个终端的干扰邻区集合：
UE1的干扰邻区集合：{Cell5，Cell6}；
UE2的干扰邻区集合：{Cell2}；
UE3的干扰邻区集合：{Cell4}；
UE4的干扰邻区集合：{Cell1，Cell6}。
当然，为实现精确确定干扰用户，本发明实施例将使用下列两种方法中的任一种来实现确定基站下每个终端的干扰邻区集合。
方法一、终端的位置状态+终端上报的测量信息
针对基站下的任一个终端，通过下列方法步骤实现：
步骤A1、基站根据终端上报的测量信息，确定终端的邻小区及每个邻小区的参考信号接收功率。
以上述例子为例，可确定每个终端的邻小区及每个邻小区的参考信号接收功率分别为：
UE1：(Cell5，-105dBm)、(Cell6，-98dBm)；
UE2：(Cell2，-95dBm)；
UE3：(Cell4，-90dBm)；
UE4：(Cell1，-98dBm)、(Cell6，-99dBm)。
步骤B1、基站确定终端的位置状态，所述位置状态用于指示终端在基站下的相对位置；若所述位置状态为小区中心，则转到步骤C1，若所述位置状态为小区边缘，则转到步骤D1。
终端的位置状态可以通过多种方法进行判决获得，为公知技术，一般常用方法是通过终端与基站的空间距离远近来判决，设定一个参考信号的接收功率门限RSRPth，例如设定为-95dBm，当终端的参考信号接收功率(Reference Signal Receiving Power，RSRP)大于该门限，则认为该终端的位置状态为小区边缘，反之为小区中心；或者也可以通过服务基站与邻基站的质量差来确定用户是否处于小区边缘，当邻区质量比本服务小区质量大于某一门限值时，认为该终端的位置状态为小区边缘，反之为小区中心。
步骤C1、基站将终端的邻小区中除目标邻小区之外的所有邻小区构成的集合，作为终端的干扰邻区集合，所述目标邻小区为终端的邻小区中参考信号接收功率小于预设干扰门限的邻小区。
该步骤中，终端的位置状态为小区中心，即终端位于基站中心位置或靠近中心位置，则将终端的邻小区中除目标邻小区之外的所有邻小区构成的集合，作为终端的干扰邻区集合，之所以不考虑目标邻小区，是因为目标邻小区的参考信号接收功率小于预设干扰门限，因而可以认为该终端对该目标邻小区造成干扰的可能性较小，为减少基站开销，因此对于此类邻小区，不予以考虑。
步骤D1、基站将终端的邻小区构成的集合，作为终端的干扰邻区集合。
对于位置状态为小区边缘的终端，则直接将终端的邻小区构成的集合， 作为终端的干扰邻区集合，之所以这么设置，是因为位于小区边缘的终端对于邻小区很有可能造成干扰，因此需要都考虑在内。
举例来说，假设UE1的位置状态为小区中心，UE2、UE3、UE4的位置状态为小区边缘，则：
针对UE1：将预邻区参考信号接收功率小于预设干扰门限(假设Ith＝-99dBm)的邻区Cell5删除，获得干扰邻区集合。
针对UE2、UE3、UE4，直接将邻小区构成的集合作为干扰邻区集合。
最终得到的每个UE的干扰邻区集合分别为：
UE1干扰邻区集合：{Cell6}；
UE2干扰邻区集合：{Cell2}；
UE3干扰邻区集合：{Cell4}；
UE4干扰邻区集合：{Cell1，Cell6}。
方法二、终端的质量状态+终端上报的测量信息
针对基站下的任一个终端，通过下列方法步骤实现：
步骤A2、基站根据终端上报的测量信息，确定终端的邻小区及每个邻小区的参考信号接收功率。
在步骤与上述步骤A1相同，此处不再赘述。
步骤B2、基站确定终端的质量状态，所述质量状态用于指示终端在基站下受干扰情况，若所述质量状态为未受干扰，则转到步骤C2，若所述质量状态为受干扰，则转到步骤D2。
在该步骤中，是确定终端的质量状态，其中，质量状态用于指示终端在基站下受干扰情况。用户的质量状态分为受干扰和未受干扰，可以通过终端的信干噪比与预设信干噪比门限进行比较，例如设定该门限为6dB，终端的信干噪比大于预设信干噪比门限时，则该终端的质量状态为未受干扰状态，反之则为受干扰状态。
步骤C2、基站将终端的邻小区中除目标邻小区之外的所有邻小区构成的集合，作为终端的干扰邻区集合，所述目标邻小区为所述终端的邻小区中参 考信号接收功率小于预设干扰门限的邻小区。
在步骤与上述步骤C1相同，此处不再赘述。
步骤D2、基站将终端的邻小区构成的集合，作为终端的干扰邻区集合。
该步骤与上述步骤D1相同，此处不再赘述。
上述步骤102中，基站根据干扰邻区集合中每个邻区的受干扰类型，确定终端的功控指示类型，其中，每个邻区的受干扰类型用于指示每个邻区的受干扰程度。并且，邻区的受干扰情况可以通过X2接口传递的过载指示来表示，也可以通过本地集中控制单元发送的邻区干扰指示来表示。
一种可选的实现方式为：将邻区的受干扰类型分为强干扰、中干扰和低干扰，其中，强干扰指的是干扰强度大于第一干扰阈值的干扰，中干扰指的是干扰强度小于或等于第一干扰阈值，且大于或等于第二干扰阈值的干扰，低干扰指的是干扰强度小于第二干扰阈值的干扰，其中，第一干扰阈值大于第二干扰阈值。
在该划分方式下，则：
若一个终端的干扰邻区集合中存在至少一个邻区的受干扰类型为强干扰，则基站确定该终端的功控指示类型为功控限制；
若一个终端的干扰邻区集合中所有邻区的受干扰类型均不为强干扰，且存在至少一个邻区的受干扰类型为中干扰，则基站确定该终端的功控指示类型为功控保持；
若一个终端的干扰邻区集合中所有邻区的受干扰类型均为低干扰，则基站确定该终端的功控指示类型为功控提升。
其中，当终端的功控指示类型为功控限制时，则基站减小终端的上行内环功率控制中的增长步长，以及减小终端的上行外环功率控制中的目标信干比；
例如，增长步长一般包含-3，1，2，3，假设当前增长步长为3，若确定终端的功控指示类型为功控限制，则可以将当前增长步长由3减小为2，或者减小为1，或者减小为-3(即降低上行内环功率)。
以及，终端的上行外环功率控制中的目标信干比指的是终端上行外环功率的信干比的最大值，当减小该值时，意味着降低终端的最大发射功率，因而可以达到控制终端上行发送功率的目的。
当终端的功控指示类型为功控保持，则基站对终端保持原功控策略；
当终端的功控指示类型为功控提升，则基站增大终端的上行内环功率控制中的增长步长，以及增大终端的上行外环功率控制中的目标信干比。
假设当前增长步长为1，若确定终端的功控指示类型为功控提升，则可以将当前增长步长由1增长为2，或增长为3。
上述步骤103中，基站根据确定的功控指示类型，控制终端的上行功率。
具体地，即分为：功控限制、功控保持和功控提升。
结合上述例子，假设：已知邻区Cell1的受干扰类型为低干扰，邻区Cell2的受干扰类型为低干扰，邻区Cell4的受干扰类型为中干扰，邻区Cell5的受干扰类型为低干扰，邻区Cell6的受干扰情况为强干扰，基站Cell0根据终端的干扰邻区集合以及邻区的受干扰类型，确定每个终端的功控指示类型，并根据功控指示类型控制终端的上行功率。
具体地，由于UE1的干扰邻区集合中有一个邻区即邻区Cell6的受干扰类型为强干扰，则该用户的功控指示为功控限制；
UE2的干扰邻区集合中所有邻区的受干扰类型为低干扰，则该用户的功控指示为功控提升；
UE3的干扰邻区集合中没有邻区的受干扰类型为强干扰，但是有一个邻区(邻区Cell4)的受干扰情况为中干扰，则该终端的功控指示为功控保持；
UE4的干扰邻区集合中有一个邻区即邻区Cell6的受干扰类型为强干扰，则该终端的功控指示为功控限制；
最后分别得到UE1～UE4的功控指示为：
UE1的功控指示：{Cell6(强干扰)}——功控限制；
UE2的功控指示：{Cell2(低干扰)}——功控提升；
UE3的功控指示：{Cell4(中干扰)}——功控保持；
UE4的功控指示：{Cell1(低干扰)，Cell6(强干扰)}——功控限制。
由上可知，针对UE1和UE4均要执行功控限制操作：对该类终端，减小终端的上行内环功率控制中的增长步长，以及减小终端的上行外环功率控制中的目标信干比；
针对UE3执行功控保持操作：对该类终端保持原功控策略，该功控策略可以是公知的上行内环和上行外环功控策略；
针对UE2执行功控提升操作：对该终端，增大终端的上行内环功率控制中的增长步长，以及增大终端的上行外环功率控制中的目标信干比。

与现有技术相比，本发明实施例具备如下优点：
1、基站获得终端的干扰邻区集合，精确划分终端的潜在干扰邻区，以终端为单位分别进行功率控制，不综合所有邻区的干扰情况对某一类或者某一部分终端进行功率控制，减少终端功率误调概率，使得***资源最大化利用；
2、基站根据终端的干扰邻区集合以及邻区的干扰情况确定每个终端的功控指示，并执行相应的功控操作，主要表现为综合终端对应的干扰邻区的干扰指示，在邻区受到干扰时，降低干扰源终端的功率；在邻区没有受到干扰时，提升非干扰源终端的功率，根据干扰情况执行相应的功率控制操作，提升***资源利用率，达到降低小区间干扰以及提升***性能的目的。
利用本发明实施例的方法，能够快速定位干扰源终端，根据小区干扰情 况有针对性的区分不同终端的功控操作，达到降低小区间干扰，提升终端感知的目的，且本发明实施例算法复杂度低，易于实现。
