With characteristic of enhanced multimedia broadcast/multicast service(E-MBMS) networks,a time-frequency two dimensions(2-D) resource allocation algorithm based on power-saving is proposed.In time domain,the proposed algorithm minimizing power consumption merges different E-MBMS sessions and minimizes the total number of receiving slots.Allocation in frequency domain is aimed at maximizing system throughput under the condition in which the target rates can be attained.The proposed scheduling algorithm is done in each orthogonal frequency division multiplexing(OFDM)frame,it allocates time-frequency units to different sessions.Simulation shows that the efficiency of proposed allocation algorithm can obviously reduce power consumption of MBMS handsets and will be with significant higher fairness with throughput being close to the upper bound of optimum method.
