Abstract
This paper makes use of the feature of space channel of the massive MIMO which means that the channel of each user in the beam domain focus on part of the beam to propose a kind of multi-user scheduling algorithm based on BDMA transmission. This algorithm takes the system and the rate as the principles to simplify the uplink and rate expression. The expression only needs to perform the calculation of the determinant according to the received related matrix of the base station. The dimension is only related to the quantity of the beam received by a single user. This paper obtains the instantaneous channel status information on the maximum beam of channel gain of each user through the estimation of the LS channel, also provides the transmission method selected by the beam, proposes to simplify the greedy algorithm for the user scheduling and at last perform the simulation directly at the multi user MIMO system user scheduling and characteristics of BRE which highlights the advantages of the algorithm.
