Abstract
In this paper, we propose a novel cooperative transmission strategy with broadcasting and cellular communication in a hybrid network system. With the help of cellular base station (CBS), two cooperative schemes are analyzed to improve broadcast performance. We define two thresholds in this paper. For users whose channel quality information (CQI) is less than the low threshold, e.g., the users near the edge of the broadcast cell, we deploy cooperative diversity transmission. Meanwhile, cooperative multiplexing transmission is exploited for users whose CQI is greater than the high threshold, such as those near the broadcasting base station (BBS). Our simulation results validate the effectiveness of our proposed cooperative schemes.
