M2M通信资源次优分配算法研究
Research on Suboptimal Resource Allocation Algorithm for M2M Communications
【摘要】 考虑性能与实现复杂度的折中,提出次优的正交多址接入中接入信道与数据传输信道之间的资源分配算法。根据上行传输资源的数量,以接入容量最大化为准则,推导信道资源分配比例与终端负载关系的表达式,采用简化算法求解次优解。确定机器与机器通信终端数量所属的终端数量区间,根据对应关系,获得与所确定的终端数量区间对应的资源分配区间,根据所获得的资源分配区间,进行上行资源的分配。
【Abstract】 Considering the performance and implementation complexity, suboptimal resource allocation between access channeland data transmission channel in the orthogonal multiple access is proposed. According to the number of uplink transmission resources, the relationship between channel resource allocation proportion and the terminal load is derived to maximize the capacity,which adopts a simplified algorithm to solve the suboptimal solution. The interval of number to which the terminal load belongs isdetermined, and the suboptimal resource allocation is derived according to the corresponding interval of resource allocation.
