技术领域
本申请涉及通信技术领域，尤其涉及一种资源分配方法及装置。
背景技术
目前，长期演进(Long Term Evolution，LTE)系统中的一种上行传输资源分配方案中，网络设备需要与终端设备进行多次信息交互才能实现网络设备为终端设备分配上行传输资源。当终端设备发生变化时，例如终端设备与网络设备之间物理距离发生变化，网络设备需要重新为终端设备分配上行传输资源。但随着系统中终端设备数量的增加，例如第五代移动通信技术(5 th Generation，5G)系统中的终端设备的数量大大增加，由于这种方案中网络设备需要与系统中的每个终端设备进行多次信息交互以实现网络设备为每个终端设备分配上行传输资源，因此会导致上行传输资源分配过程存在实施难度大、时间消耗长、信令开销大的问题。
另一种上行传输资源分配方案中，网络设备通知终端设备其可用的上行传输资源，终端设备可以从网络设备通知的所有可用的上行传输资源中随机选择用于该终端设备进行上行传输的资源。但这种方案中可能会出现多个终端设备选择到相同的上行传输资源，进而引起资源碰撞，造成终端设备的传输效率低，甚至传输失败。
综上，现有的上行传输资源分配方案均不能较佳地实现为终端设备分配上行传输资源。

下面结合说明书附图对本申请各个实施例进行详细描述。需要说明的是，本申请实施例的展示顺序仅代表实施例的先后顺序，并不代表实施例所提供的技术方案的优劣。
如图1所示，本申请实施例提供了一种资源分配方法，该方法包括：
S101、终端设备接收网络设备广播的第一对应关系和第二对应关系，其中第一对应关系包括信道状态信息的取值范围与终端设备对应的等级的对应关系，第二对应关系包括终端设备对应的等级与上行传输资源的集合的对应 关系。
本实施例中，终端设备的信道状态信息包括但不限于参考信号的接收功率、导频信号的接收强度、信噪比等信道状态信息。
上行传输资源包括但不限于时域资源、频域资源、码域资源等资源。其中，时域资源可以是时隙等，频域资源可以是频点、频率字带等，码域资源可以是不等分集度码字等。
S101中，终端设备接收网络设备广播的消息，获取接收到的消息中携带的第一对应关系和第二对应关系，其中，网络设备广播的消息可以是系统消息，也可以是其他消息。第一对应关系和第二对应关系可以携带在网络设备广播的一个消息中，也可以分别携带在网络设备广播的不同消息中。
可选的，在S101之前网络设备可以根据自身获取到的终端设备的信道状态信息确定初始的第一对应关系，或者在S101之前预先配置初始的第一对应关系。进一步的，在网络设备确定初始的第一对应关系之后，或者在预先配置初始的第一对应关系之后，网络设备可以周期性地更新第一对应关系。
S102、终端设备确定自身的信道状态信息的取值，并根据自身的信道状态信息的取值和第一对应关系确定自身对应的等级。
S102中，终端设备可以通过将该终端设备的信道状态信息的取值与第一对应关系中信道状态信息的取值范围进行匹配，确定该终端设备的信道状态信息的取值所处的信道状态信息的取值范围，从而将该取值范围对应的终端设备对应的等级确定为该终端设备确定的等级。
以终端设备的信道状态信息包括参考信号的接收功率为例，假设终端设备的接收功率的取值为4dB，第一对应关系即终端设备的接收功率的取值范围与终端设备对应的等级的对应关系如下表1所示。
表1参考信号的接收功率的取值范围与终端设备对应的等级的对应关系
终端设备对应的等级 参考信号的接收功率(dB)的取值范围
第一级 1至3
第二级 4至5
第三级 6至7
第四级 8至9
终端设备将自身的参考信号的接收功率的取值4dB与表1中的第一对应关系中的终端设备的接收功率的取值范围进行匹配，该终端设备的参考信号的接收功率的取值4dB对应的取值范围为4至5dB，该取值范围对应的终端设备对应的等级为第二级，因此终端设备对应的等级为第二级。
在S102之前，终端设备获取该终端设备的信道状态信息。例如在终端设备的信道状态信息包括参考信号的接收功率的情况下，终端设备可以确定自身的参考信号的接收功率。
S103、终端设备根据自身对应的等级和第二对应关系，确定自身对应的上行传输资源的集合，并在确定的上行传输资源的集合中选择上行传输资源。
其中，第二对应关系中终端设备对应的等级越高，其对应的上行传输资源的集合包括的上行传输资源的质量越好。例如，第二对应关系中终端设备对应的等级越高，其对应的上行传输资源的集合包括的上行传输资源的干扰噪声(Interference over Thermal，Iot)越低，上行传输资源的质量越好。
在多个终端设备的接收功率的取值相近的情况下，例如多个终端设备的接收功率的取值均处于3至5dB内，即使这些终端设备采用相同的传输资源进行上行传输，网络设备也可以准确的解调出这些终端设备的上行传输的消息，这个原理称为串行干扰消除原理。
基于上述串行干扰消除的原理，S103中终端设备将自身对应的等级与第二对应关系中上行传输资源的集合进行匹配，确定与终端设备对应的等级相匹配的上行传输资源的集合，并在该上行传输资源的集合中随机选择出上行传输资源。由于对应同一个上行传输资源的集合的多个终端设备的信道状态信息的取值在一个取值范围内，即这多个终端设备的信道状态信息的取值相近，基于上述串行干扰消除的原理，即使多个终端设备在一个上行传输资源 的集合中选择到相同的上行传输资源，网络设备也可以准确的解调出多个终端设备采用相同上行传输资源传输的消息，避免了由资源碰撞造成的终端设备的传输效率低，甚至传输失败的问题，提升终端设备的传输效率。
可选的，终端设备可以根据该终端设备对应的等级和预设的终端设备对应的等级与终端设备的发送功率范围的对应关系，确定终端设备对应的等级对应的终端设备的发送功率范围，并在确定的终端设备的发送功率范围中选择上行传输时采用的发送功率。
可选的，在S103之前终端设备可以根据预设条件确定终端设备的优先级。S103中终端设备可以根据自身的优先级和预设的优先级与资源的映射关系，在确定的上行传输资源的集合中选择该终端设备的优先级映射的资源。例如，终端设备根据自身的服务质量(Quality of Service，Qos)等级确定自身的优先级，根据自身的优先级和预设的优先级与资源的映射关系，在确定的上行传输资源的集合中选择该终端设备的优先级映射的资源，以便为不同Qos等级的终端设备提供不同的资源，提升终端设备的传输效率，提高资源的利用率。
可选的，终端设备采用选择出的上行传输资源向网络设备上报的该终端设备的信道状态信息的取值，上报的信道状态信息的取值用于网络设备更新第一对应关系。网络设备接收终端设备上报的自身的信道状态信息后，根据终端设备上报的自身的信道状态信息对第一对应关系进行更新，并向终端设备广播更新后的第一对应关系。这样通过网络设备更新调整第一对应关系，既可以使终端设备选择到更符合自身上行传输的要求的上行传输资源，进而提升终端设备的传输效率，也可以减少上行传输资源的浪费。
可选的，终端设备接收网络设备广播的更新后的第一对应关系，终端设备根据自身的信道状态信息的取值和更新后的第一对应关系，确定自身对应的等级，以便终端设备选择到更符合自身上行传输的要求的上行传输资源，进而提升终端设备的传输效率，也可以减少上行传输资源的浪费。
本申请实施例提供的一种资源分配方法中，终端设备根据自身的信道状 态信息的取值和接收到的网络设备广播的第一对应关系来确定终端设备对应的等级，第一对应关系为信道状态信息的取值范围与终端设备对应的等级的对应关系，再根据该终端设备对应的等级和第二对应关系来确定该终端设备对应的等级对应的上行传输资源的集合，第二对应关系为终端设备对应的等级与上行传输资源的集合的对应关系，进而终端设备可以在该上行传输资源的集合中选择出上行传输资源，实现了为终端设备分配上行传输资源，降低了5G系统中为终端设备分配上行传输资源的实施难度，减少了5G系统中为终端设备分配上行传输资源的时间消耗和信令开销。另外，由于对应同一个上行传输资源的集合的多个终端设备的信道状态信息的取值在一个取值范围内，还避免了由于多个终端设备选择到相同的上行传输资源而造成的终端设备的传输效率低，甚至传输失败的问题，提升终端设备的传输效率
如图2所示，本申请实施例提供了一种资源分配方法，该方法包括：
S201、网络设备确定第一对应关系，该第一对应关系包括信道状态信息的取值范围与终端设备对应的等级的对应关系。
S201中，网络设备可以根据自身获取到的终端设备的信道状态信息确定初始的第一对应关系，或者预先配置初始的第一对应关系；在确定初始的第一对应关系之后，或者在预先配置初始的第一对应关系之后网络设备可以确定调整信息，网络设备基于至少一个终端设备的信道状态信息更新第一对应关系，并向终端设备广播更新后的第一对应关系，以便网络设备可以为信道状态不同的终端设备配置更符合这些终端设备的上行传输的要求的上行传输资源，进而提升终端设备的传输效率，减少上行传输资源的浪费。需要说明的是，网络设备可以周期性的更新第一对应关系，也可以在终端设备上报该终端设备的信道状态信息后更新第一对应关系，本实施例中不作限定。此处的第一对应关系与终端设备侧的实施例中描述的第一对应关系类似，此处不再赘述。
其中，终端设备的信道状态信息包括但不限于参考信号的接收功率、导频信号的接收强度、信噪比等信道状态信息。

可选的，网络设备根据至少一个终端设备的信道状态信息和第一对应关系来确定至少一个终端设备中每个终端设备对应的等级，对于任一等级，网络设备根据对应该等级的终端设备的信道状态信息，确定该等级对应的调整信息，并根据该等级对应的调整信息更新所述第一对应关系中该等级对应的信道状态信息的取值范围，其中每个等级的调整信息包括以下信息之一或组合：接收过载率、发送过载率、有效过载率。接收过载率为采用网络设备的上行传输资源向网络设备发送消息并被解调出的终端设备的数量与网络设备的上行传输资源可支持的终端设备的最大数量的比值，有效过载率为接收过载率的加权平均值；发送过载率为采用网络设备的上行传输资源向网络设备发送消息的终端设备的数量与网络设备的上行传输资源可支持的终端设备的最大数量的比值。
具体的，网络设备根据该等级对应的调整信息更新所述第一对应关系中该等级对应的信道状态信息的取值范围的实现方式可以为以下方式之一：
方式一：调整信息包括接收过载率和/或有效过载率时，对于同一等级，若调整信息小于预设的第一阈值，说明在该等级的终端设备中采用网络设备的上行传输资源向网络设备发送消息并被解调出的终端设备的数量较少，在该等级的终端设备的传输质量达不到实际应用的要求，则网络设备将第一对应关系中该等级对应的信道状态信息的取值范围缩小，以减少采用该等级对应的上行传输资源进行传输的终端设备的数量，提升该等级的终端设备的传输效率。
调整信息包括接收过载率和/或有效过载率时，对于同一等级，若调整信息大于或等于预设的第二阈值，说明在该等级的终端设备的传输质量达到实际应用的要求，则网络设备可以将第一对应关系中该等级对应的信道状态信息的取值范围扩大，以便提高上行传输资源的利用率，减少上行传输资源的 浪费。或者若调整信息大于或等于预设的第二阈值，则网络设备也可以保持第一对应关系中该等级对应的信道状态信息的取值范围不变。
其中，第一阈值小于或等于第二阈值。需要说明的是，除了采用第一阈值和第二阈值来实现上述方式一之外，还可以采用一个或两个以上的阈值来实现上述方式一，本实施例中不作限定。
方式二：调整信息包括发送过载率时，对于同一等级，若发送过载率大于预设的第三阈值，说明在该等级的终端设备中采用网络设备的上行传输资源向网络设备发送消息的终端设备的数量较多，可能会导致在该等级的终端设备的传输质量达不到实际应用的要求，则网络设备将第一对应关系中该等级对应的信道状态信息的取值范围缩小，以减少采用该等级对应的上行传输资源进行传输的终端设备的数量，提升该等级的终端设备的传输效率。
调整信息包括发送过载率时，对于同一等级，若调整信息包括的发送过载率小于或等于预设的第六阈值，说明在该等级的终端设备的传输质量达到实际应用的要求，则网络设备将第一对应关系中该等级对应的信道状态信息的取值范围扩大，以便提高上行传输资源的利用率，减少上行传输资源的浪费；或者若调整信息小于或等于预设的第二阈值，则网络设备可以保持第一对应关系中该等级对应的信道状态信息的取值范围不变。其中第三阈值大于或等于第四阈值。需要说明的是，除了采用第三阈值和第四阈值来实现上述方式二之外，还可以采用一个或两个以上的阈值来实现上述方式二，本实施例中不作限定。
需要说明的是，除了上述两种方式之外，根据实际应用的要求，还可以采用其它方式对第一对应关系中该等级对应的信道状态信息的取值范围进行调整。
S202、网络设备确定第二对应关系，该第二对应关系包括终端设备对应的等级与上行传输资源的集合的对应关系。
其中，第二对应关系中终端设备对应的等级越高，其对应的上行传输资源的集合包括的上行传输资源的质量越好。
S202中，网络设备可以根据自身获取到的终端设备的信道状态信息确定第二对应关系，或者预先配置第二对应关系。需要说明的是，此处的第二对应关系与终端设备侧的实施例中描述的第二对应关系类似，此处不再赘述。
本实施例中，S201可以在S202之前执行，S201也可以在S202之后执行，S201还可以和S202一起执行，本实施例中对执行S201和S202的先后顺序不作限定。
