Abstract :
In this paper, a scheme of multiple cells downlink joint transmitting for OFDMA system is introduced. The system and cell edge spectrum efficiency gain from the joint transmission is analyzed. The main factor to get the gain is the geography area selection of joint transmitting. Moreover, multiple users´ joint transmitting provides the more significant gain than single users´ joint transmitting.
