Abstract :
This paper deals with packet scheduling in SDMA based wireless cellular networks. Depending on the terminal´s positions and the capabilities of the antenna and signal processing system it is possible for more than one mobile terminal to receive or to transmit simultaneously. We discuss the two-dimensional scheduling problem and address the spatial as well as the temporal domain. Based on the framework of batch Markovian arrival processes we develop an analytical model for the air interface and present some results for uplink capacity request transmissions
