Resource allocation for minimum satisfaction guarantees in multi-service and multi-antenna networks

摘要

Radio resource allocation techniques for MIMO systems are disclosed, wherein SDMA groups that should be multiplexed on each frequency chunk in order to maximize the total downlink data rate are selected, while guaranteeing that a specified minimum number of flows from each service have their instantaneous QoS demands fulfilled. The disclosed techniques include an unconstrained maximization procedure, in which resources are initially allocated to data flows for each of several data services, followed by a reallocation procedure in which resources are reallocated to satisfy minimum satisfaction constraints for each data service.
