本公开的较佳实施方式
下面结合附图对本公开的实施方式进行描述。
第一实施例：
基站在为小区中的移动终端分配时频资源时，可以是通过与小区中的每个移动终端进行实时的协商，对每个移动终端进行固定的资源分配，而协商的过程非常复杂繁琐，导致了基站的梳理效率非常低，本公开实施例提供了一种资源分配方法，能够提高效率，请参见图1，图1为本实施例提供的资源分配方法，该方法大致是针对于基站对资源的分配提出的。可选的分配流程如下所示：
S100，基站获取该基站下挂的小区的工作参数，该小区指的是基站信号所覆盖的区域内的小区；
该工作参数可包括该小区的用户数量、同一时频资源所支持一次数据发送的最大终端数量、时频资源循环周期和该小区的系统帧号的循环周期，可选地，该用户数量为小区所能支持的最大用户数量，所述时频资源循环周期可以理解为是系统帧中可被移动终端使用的时频资源的循环周期，所述系统 帧号的循环周期指的可以是该小区中的所用系统帧进行一次循环所需要的时间。
S101，根据该工作参数计算该小区所分配的可用时频资源数量。
该可用时频资源数量可用于在移动终端上计算用于所述移动终端数据发送的终端可用时频资源，可选地，该可用时频资源数量为该小区中的所有移动终端都能进行一次数据发送所需要时频资源个数。
在本实施例中，基站计算分配小区的可用时频资源还可以包括，对每个时频资源的大小、调制阶数，以及每个时频资源所能传输的数据量进行限定，例如，进行配置。
S102，将该可用时频资源数量发送至该小区的所有待发送数据的移动终端。
在该步骤中，对于该可用时频资源的发送，可选地，将该可用时频资源添加到基站的系统消息中，通过基站将该系统消息通过广播的方式下发给小区中的每个移动终端上。
在本实施例中，对于步骤S101，在计算可用时频资源数量过程中，可以是通过计算两个比值，并从两个比值中选择最小值作为可用时频资源数量。
可选地，计算该小区的用户数量与该最大终端数量的比值，并对该比值进行上取整，得到第一比值；
计算系统帧号的循环周期与时频资源循环周期的比值，并对该比值进行上取整，得到第二比值；
然后，从第一比值和第二比值中选择一个最小值，并将该选择的最小值作为可用时频资源数量下发给小区的所有移动终端，可用时频资源数量的计算公式可以如下：
Figure PCTCN2018079488-appb-000001
其中，NumOfSched为可用时频资源数量，MaxUeNum为小区的用户数量，MaxUeNumPerResource为一个时频资源所支持一次数据发送的最大终端数量，Tresource为时频资源循环周期，T为小区的系统帧号的循环周期，min 表示取最小值，ceil表示上取整运算。
在本实施例中，在从第一比值和第二比值中选择一个最小值之前，还可以包括：获取比值的修正系数，根据该修正系数对第二比值极性修正处理，然后再从第一比值和修正后的第二比值中选择一个最小值作为可用时频资源数量下发给小区的所有移动终端，可用时频资源数量的计算公式可以如下：
Figure PCTCN2018079488-appb-000002
其中，NumOfSched为可用时频资源数量，MaxUeNum为小区的用户数量，MaxUeNumPerResource为一个时频资源所支持一次数据发送的最大终端数量，Tresource为时频资源循环周期，T为小区的系统帧号的循环周期，alpha为第二比值的修正系数，min表示取最小值，ceil表示上取整运算。
在实际应用中，当基站接收到小区移动终端注册指令或者小区建立指令时，基站可以对小区的用户数量进行设置，并获取一个时频资源所支持一次数据发送的最大终端数量，系统帧中的时频资源循环周期，以及小区的系统帧号的循环周期，在进行注册或建立时，基站可以根据上述的信息自动生成相关的参数，并将该参数放入系统消息中下发给小区的每个移动终端，相关处理步骤可以如图2、3所示。
S200，计算小区中的所有移动终端都有一次数据发送所需要的时频资源数NumOfSched。
假设MaxUeNum为100，MaxUeNumPerResource为5，Tresource为10毫秒(ms)，T为10240ms，alpha为0，则可以有：
Figure PCTCN2018079488-appb-000003
Figure PCTCN2018079488-appb-000004
NumOfSched＝min(20，10240)＝20。
S201，将NumOfSched放入系统消息中，通过广播方式通知小区中的所有移动终端。
在实际应用中，该基站在获取工作参数时，还可以是将该基站所管理的所有小区的工作参数都获取过来，然后根据每个小区的工作参数为该小区进行可用时频资源的计算分配，当该小区中的移动终端需要发送数据时，可以直接根据资源的分配结果自行计算，不需要再请求基站下发，从而缩短了移动终端与基站的交互时延，提高了移动终端的数据发送效率。
本公开实施例提供的资源分配方法，通过获取基站预先为小区分配的工作参数，根据所述工作参数计算所述小区分配的可用时频资源数量，该可用时频资源数量用于在移动终端上计算该移动终端数据发送的终端可用时频资源，最后将所述可用时频资源发送至小区中的所有移动终端；通过对本实施例提供的资源分配方法的实施，该基站只需要根据小区的工作参数对小区的时频资源进行分配即可，不需要与移动终端进行实时的协商交互，从而减少了基站与移动终端之间的信令交互，提高了基站的资源分配效率，同时也缩短了移动终端与基站的交互时延，提高了移动终端的数据发送效率。

可选地，在计算该可用时频资源数量时，可以是根据该小区的用户数量和该最大终端数量计算第一比值，以及根据系统帧号的循环周期和该时频资源循环周期计算第二比值，然后通过比较第一比值和第二比值的大小，选择 其中的最小值作为该可用时频资源数量。
