The massive-antenna is widely considered as one of key technologies in the 5th generation (5G) networks and beyond. To approach the system capacity with the massive-antenna, it is highly demanded for fundamental research on how to obtain the system capacity of massive-antenna based broadcast channel (BC) with simple closed-form expressions. To address this, our paper focuses on the massive-multiple-input single-output (mMISO) BC transmission, which is a common scenario in cellular networks. With regarding the massive-antenna, a precise approximation of the system capacity is derived with a simple closed-form expression. The simulations validate the correctness of the derived outcomes in mMISO-BC.
