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 analysed to improve hybrid network performance, which does not affect the original broadcasting signal. We investigate two cooperative schemes based on the different channel quality information (CQI) in this paper. For users whose CQI is less than the defined 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 defined high threshold, such as those near the broadcasting base station (BBS). Furthermore, we propose a new quasi-orthogonal coding scheme with nested structure applying to the cooperative diversity scheme, which can be easily employed in two or three CBS cooperative scenarios. Our simulation results validate the effectiveness of our proposed cooperative schemes.
