In recent years , there has been an exponential increase in the number of mobile phone users. In addition, a signi ficant growth in the demand for high-rate multimedia services over wireless networks , such as video conferencing, multimedia streaming, etc., was noted. Different solutions were proposed to suppor t high-quali ty high data rate delivery to mobile users, including resource allocation techniques for packet-radio-based next generation cellular networks.

In this paper , an efficient time slot allocation method—Dynamic Time Slot Par titioning (DTSP) algori thm based on statistical multiplexing is proposed for a two-hop cel lular architecture. In DTSP, the available bandwidth resources are increased by par titioning each time slot into several minislots wherein different numbers of minislots are allocated to di fferent users.

The DTSP algori thm is based on asynchronous time-division multiplexing, wherein users with variable number of packets in their buffers can transmit data sequentially wi thout any loss in the overall available resources .

The key advantage of DTSP is that i t can flexibly adapt to di fferent quali ty of service requirments , especially when combined wi th adaptive modulation. It has been observed that the sys tem capaci ty achieved by the DTSP algor ithm in the
downlink mode using adaptive modulation is up to 41 percent higher than when existing solutions are employed.

In addi tion, DTSP results in significantly lower time for data transmission than the state-of-the-art region and time par titioning techniques.
