This paper addresses the resource allocation problem for multi-user MIMO systems with consideration of real-time services. Specifically, the authors focused on the delay constraints modeling in this paper, since it is a fundamental QoS requirement for all real-time services. To simultaneously meet the delay constraints of all users, they first modeled this resource allocation problem with specific delay restrictions as a bargaining game. Based on the Nash bargaining solution, they derived the system utility function that achieves delay constraints in a long term.
