中文摘要：

针对功率最小化问题,提出了一种联合双时隙的资源分配算法,利用相邻两个时隙信道状态整体一致而又具有差异的性质,根据第1时隙的信道状态,将信道状态好的用户的第2时隙的部分或全部速率提前分配,从而使信道增益大的子载波承载了较多的速率,最终降低了系统功率消耗。仿真结果表明,所提双时隙资源分配算法既能保证用户双时隙内的目标速率,又能够有效降低系统的功率消耗。

英文摘要：

A resource allocation algorithm based on double slots was proposed to minimize the transmitting power in wireless communications. Being aware of the channel difference between the two adjacent slots, the second slot was allocated in advance partial of the data rate conventionally scheduled to the first slot when the corresponding user had perfect channel state. Consequently, most of the required data was loaded by the sub-carriers with fine channel gain and finally less transmitting power was needed. The simulation results indicate that the proposed algorithm can effectively decrease the transmitting power while meeting the users ＇ target rate requirement.
