英文摘要	In order to further improve the packet data service performance,the Continuous Packet Connectivity(CPC)mode has been proposed as a configuration in 3GPP Rel’07.For the burst type data,even in the case of no data transmission,the frequent power control signaling also needs to be performed,which brings considerable overhead to system and increases system instability.In this paper,a simplified centralized power control strategy is proposed for small packet transmission by taking full consideration of resource allocation and interference of different users in the sector,in replacement of the one in the conventional strategy.Simulation results indicate that the proposed strategy can use system resources more efficiently and improve the system stability effectively.User throughput can be improved by nearly 25% without increasing the packet delay.; In order to further improve the packet data service performance,the Continuous Packet Connectivity(CPC)mode has been proposed as a configuration in 3GPP Rel’07.For the burst type data,even in the case of no data transmission,the frequent power control signaling also needs to be performed,which brings considerable overhead to system and increases system instability.In this paper,a simplified centralized power control strategy is proposed for small packet transmission by taking full consideration of resource; IEEE; 5
