N2 - Base stations (BSs) cooperative transmission provides high spectrum efficiency for cellular networks, where the performance gain of each user depends on its location. When training overhead is considered, however, a user jointly served by multiple BSs may even achieve lower net rate than with non-cooperative transmission. In this paper, we consider semi-dynamic mode selection for users. We first derive the average rate of each user when it is served under cooperative or non-cooperative transmission. We then propose a closed-form mode selection method where only large-scale fading gains of a user are used. Simulation results validate our analysis and demonstrate a performance gain of the proposed method over both full cooperative and non-cooperative transmission.
