%X In this paper a wireless packet transmission scheme over Multiple Input Multiple Output (MIMO) Gaussian Broadcast Channel (GBC) is proposed.Specifically,the transmission packet delay constraint and broadcast channel capacity are considered jointly,based on QR decomposition of channel and Dirty Paper Coding (DPC),a greedy algorithm is used to exploit multiuser diversity as well as transmission packet delay constraint in base station.It demonstrates that the packet arrival rate,achievable service rate,user number and transmitting antenna number can be formulated into an optimization problem.The simulation results show that the proposed scheme can maximize the system throughput,while providing guarantees on delay performance.
