具体实施方式
下面对文中出现的一些词语进行解释：
1、本公开实施例所指的“终端”是手机、平台等。
2、本公开实施例所指的“网络侧设备”是宏基站、微基站等。
3、“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。
对于集中式的干扰协调方案，中心节点需要进行大量的信息交互，然后进行高复杂度的集中优化处理。相应的，大量的信息交互对基站交互接口的承受能力、中心节点的计算能力有很高的要求，而如此高要求的系统复杂性显然是无法满足5G密集化场景的需求。
综上，目前集中式的干扰协调需要大量的信息交换，造成极大的信令开销。
下面结合说明书附图对本公开实施例做进一步详细描述。
如图1所示，一种干扰协调的方法和设备，包括：终端10和网络侧设备 20。
终端10：用于将当前时隙的干扰信息和/或下一时隙的服务质量QoS需求数值发送给网络侧设备，以使所述网络侧设备根据收到的所述干扰信息和/或下一时隙的QoS需求数值调整下一时隙针对所述终端的发射参数。
网络侧设备20：用于接收终端对应的当前时隙的干扰信息和/或下一时隙的QoS需求数值；根据收到的所述干扰信息和/或下一时隙的QoS需求数值调整下一时隙针对所述终端的发射参数。
通过上述方案，所述终端确定当前时隙的干扰信息，将当前时隙的干扰信息和/或由所述当前时隙的干扰信息确定的下一时隙的QoS需求数值发送给网络侧设备，所述网络侧设备根据接收到的终端对应的当前时隙的干扰信息和/或下一时隙的QoS需求数值调整下一时隙针对所述终端的发射参数，不需要与网络侧设备交互大量的信息且所述网络侧设备能够针对所述终端每个时隙的调整。所述网络侧设备不需要再将终端上报的所述信息以及对终端产生干扰的所有网络侧设备与所述终端之间的信道状态信息发送给中心节点进行集中处理。所述网络侧设备根据接收到的终端对应的消息进行独立计算，以调整针对每个终端的传输策略，避免了大量的信息交换，节省了信令开销且系统更加灵活，进一步的，由于每个网络侧设备都可以通过计算调整自身的传输策略，所以同时也减轻了集中式处理对系统设施的性能要求。
本公开实施例，终端在确定当前时隙的干扰信息和/或下一时隙的QoS需求数值之前，需要对受到的所有干扰进行测量，得到干扰信息。若所述终端将下一时隙的QoS需求数值发送给网络侧设备，则所述终端还需要对与接入的网络侧设备之间的信道进行测量，得到本地信道状态信息，并根据当前时隙的干扰信息和当前时隙的信道状态信息确定下一时隙的QoS需求数值。
其中，QoS需求数值用于反应终端需要的QoS程度。
所述终端测量得到的所述干扰信息包括：噪声干扰和/或其他网络侧设备对终端的干扰。
本公开实施例，所述终端将当前时隙的干扰信息和/或下一时隙的QoS需 求数值发送给网络侧设备的方式有多种，下面列举几种：
发送方式一：如图2示，本公开实施例提供的第一种发送方式。
终端n将Q当前时隙的干扰信息和/或下一时隙的QoS需求数值广播给所有基站，包括：微基站1、微基站2、微基站3和宏基站。
发送方式二：如图3所示，本公开实施例提供的第二种发送方式。
终端n先单独将当前时隙的干扰信息和/或下一时隙的QoS需求数值发送给宏基站，然后由宏基站将当前时隙的干扰信息和/或下一时隙的QoS需求数值发送其他微基站，包括：微基站1、微基站2、微基站3。
上述场景仅为举例，本公开实施例适用的场景有多种，下面举例说明：
场景一：如图4所示，终端接入的网络侧设备以及其他网络侧设备全部为宏基站；
场景二：如图5所示，终端接入的网络侧设备以及其他网络侧设备全部为微基站；
场景三：如图6所示，终端接入的网络侧设备以及其他网络侧设备中既有宏基站也有微基站。
所述网络侧设备根据收到的所述干扰信息和/或下一时隙的QoS需求数值调整下一时隙针对所述终端的发射参数。
其中，所述发射参数包括但不限于下列中的至少一个：
发射功率、波束、PMI(Precoding Matrix Indicator，预编码矩阵指示)。
在实施中，本公开实施例可以以满足终端的QoS需求为目的进行调整和/或以最大化网络和速率为目的进行调整，以实现满足所述终端在使用场景变化后的不同使用需求。
不同的调整目的，在调整时用到的参数不同，比如以满足终端的QoS需求为目的进行调整用到下一时隙的QoS需求数值；以最大化网络和速率为目的进行调整用到干扰信息。
下面详细介绍下不同目的的调整方式：
方案一、以满足终端的QoS需求为目的。
比如，在所述网络侧设备服务的用户较少的情况下，例如人烟稀少的地区，网络侧设备稀疏，所述终端的通话质量容易受到干扰，在这种使用场景下，所述网络侧设备可以设置为以满足所述终端的QoS需求为目的对发射参数进行调整。
在以满足终端的QoS需求为目的进行调整时，终端需要确定下一时隙的QoS需求数值，并将下一时隙的QoS需求数值发送给网络侧设备,网络侧设备需要与其他网络侧设备交互所述终端的QoS需求数值。
其中，终端根据当前时隙的干扰信息和当前时隙的信道状态信息确定下一时隙的QoS需求数值，其中所述信道状态信息对应的信道为所述终端和接入的网络侧设备之间的信道。
比如终端可以根据下面的公式1确定下一时隙的QoS需求数值。
所述网络侧设备根据下一时隙的QoS需求数值、利用本地测量得到的与所述终端之间信道的信道状态信息以及利用本地测量得到的终端的干扰信息调整下一时隙针对所述终端的发射参数。
若所述发射参数为发射功率时，可以采用下述调整方式一的方法进行调整，具体操作可参见下述调整方式一。
方案二：以最大化网络和速率为目的。
在所述网络侧设备服务的用户较多的情况下，例如演唱会现场，所述网络侧设备的网络和速率越高，则满足网速需求的终端的数量就越多。在这种使用场景下，所述网络侧设备可以设置为以最大化网络和速率为目的，对发射参数进行调整。
终端将干扰信息发送给网络侧设备，所述网络侧设备需要与其他网络侧设备交互干扰信息但不必交互QoS需求数值，因此所述终端必须要将包含当前时隙的干扰信息发送给网络侧设备。
如图7所述，本实施例给出的一种网络侧设备交互彼此干扰信息的场景示意图。
I 0宏基站0所服务的终端0受到的所有干扰；I 1微基站1所服务的终端1 受到的所有干扰；I 2微基站2所服务的终端2受到的所有干扰；I 3微基站3所服务的终端3受到的所有干扰。
所述网络侧设备根据所述终端在当前时隙的干扰信息、利用本地测量得到的与所述终端之间信道的信道状态信息以及与相邻网络侧设备交互获得的其他网络侧设备的干扰信息调整下一时隙针对所述终端的发射参数。
若所述发射参数为发射功率时，采用下述调整方式二的方法进行调整，具体操作可参见下述调整方式二。
方案三、同时满足终端的QoS需求和以最大化网络和速率为目的。
所述网络侧设备将以同时满足QoS需求和以最大化网络和速率为目的对下一时隙针对所述终端的发射参数进行调整时就是将上面的方案一和方案二相结合。
在实施中，也可以不固定设置采用方案一还是方案二，比如可以设置一个条件，根据条件确定采用的方案。
一种可行的方式是：所述网络侧设备先判断当前是否满足所述终端的QoS需求，若满足，则所述网络侧设备进一步以最大化网络和速率为目的，对下一时隙针对所述终端的发射参数进行调整；否则，所述网络侧设备以满足所述终端QoS需求为目的，对下一时隙针对所述终端的发射参数进行调整。
其中，所述网络侧设备通过下列方式判断所述终端的QoS是否满足需求：
所述网络侧设备将当前时隙的QoS需求数值与QoS阈值进行比较，判断当前时隙的QoS需求数值是否小于QoS阈值，如果是，则确定QoS不满足需求；否则确定QoS满足需求。其中，当前时隙的QoS需求数值为所述网络侧设备已知。
QoS阈值可以根据需要设定，比如依据运营商和/或终端使用套餐的不同，具有不同的数值。
需要说明的是，所述终端在更新QoS需求数值之前也可以通过上述方式判断当前时隙的QoS是否满足需求，并根据判断结果更新下一时隙QoS需求数值，具体更新方式可以参见下述网络侧设备的更新方式，此处不再赘述。
若满足当前时隙所述终端的QoS需求，将预设数值作为所述下一时隙QoS需求数值，进一步的，所述终端以最大化网络和速率为目的，并根据所述终端在当前时隙的干扰信息、利用本地测量得到的与所述终端之间信道的信道状态信息以及与相邻网络侧设备交互获得的其他网络侧设备的干扰信息调整下一时隙针对所述终端的发射参数，若所述发射参数为发射功率时，采用下述调整方式二的方法进行调整，具体操作可参见下述调整方式一，不再详细说明。
若所述终端当前时隙的QoS不满足需求，进一步的，所述终端以满足所述终端QoS需求为目的，并根据发射参数、本地信道状态信息和干扰信息，更新出下一时隙满足QoS需求的QoS需求数值，再根据下一时隙的QoS需求数值、利用本地测量得到的与所述终端之间信道的信道状态信息以及利用本地测量得到的终端的干扰信息调整下一时隙针对所述终端的发射参数，若所述发射参数为发射功率时，采用下述调整方式一的方法进行调整，具体操作可参见下述调整方式一，不再详细说明。
具体的，所述网络侧设备通过下列公式1确定下一时隙的QoS需求数值：

其中，[ ] +表示对括号内部数据进行非负操作，内部数据小于零时取零，否则等于本身；k为当前时隙；

本公开实施例中，以发射功率作为发射参数为例，网络侧设备根据不同的干扰协调机制的目的对发射功率的具体调整分别进行具体介绍：
调整方式一：以满足终端的QoS为目的进行调整。
所述网络侧设备以满足终端的QoS需求为目的时，根据下一时隙的QoS需求数值、利用本地测量得到的与所述终端之间信道的信道状态信息以及利用本地测量得到的终端的干扰信息调整下一时隙针对所述终端的发射参数。
具体的，所述网络侧设备通过下列公式2调整下一时隙针对所述终端的发射功率：

其中，

为满足QoS需求的情况下能够达到最大可达速率的发射功率；o表示当前有QoS需求的终端所属的网络侧设备o；λ o为使得网络侧设备o内 发射功率满足功率和约束的最小非负数；μ n为当前终端n的QoS需求数值；ω o(n)为网络侧设备o下服务的用户n的本地信道状态信息归一化的结果；I o(n)表示网络侧设备o所服务的用户n所受到的干扰；h oo(n)为网络侧设备o在自身的子信道n上服务用户的信道增益；p o(n)为网络侧设备o在子信道n上的发射功率；λ i为使得网络侧设备i发射功率满足功率和约束的最小非负数；h ij(n)为网络侧设备i到网络侧设备j在子信道n上服务用户的信道增益；h ii(n)为网络侧设备i在子信道i上服务用户的信道增益；I i(n)表示网络侧设备i所服务的用户n所受到的干扰；p i(n)为网络侧设备i在子信道n上的发射功率。
上述网络侧设备针对QoS需求对下一时隙的发射功率的调整的原则为：通过管理其他网络侧设备对终端的干扰，调整发射功率以抵消掉所述终端受到的干扰的影响，在满足协调机制的目的同时需要达到最大的可达速率，若可达速率越大，所述网络侧设备向所述终端进行数据传输的信道容量以及系统性能就越强，即能够得到自身的最大效用。
本公开实施例中的，所述网络侧设备在满足协调机制的情况下能够达到最大可达速率的发射功率，即为所述网络侧设备下一时隙的发射功率
