By simultaneously transmitting and receiving signals at the same time slot with abundant spectrum, millimeter (mm)-wave based full-duplex (FD) systems has the potential to double spectrum efficiency (SE) of half-duplex (HD) transmission and to meet explosive growth of data-rate demand imposed on the future mobile networks. It has been shown that the bottleneck of mm-wave communications caused by severe pathloss problem can be alleviated by directional beamforming technique. However, the potential of mm-wave band cannot be fully exploited if beamforming resources are not properly utilized. Furthermore, major challenge of FD systems lies in the uplink (UL) communication due to coexistence of inter-user interference (IUI) and self-interference (SI). As a result, the interference energy of the uplink channel is too large, which in turn affects the performance of throughput.

SUMMARY

One object of the present invention is to provide a method and system for allocating network resources, which is capable of mm-wave full duplex communication. The invention uses an algorithm to design operation system of the present invention so as to achieve the optimal allocation of millimeter-wave full-duplex communication network resources by the dynamic channel environment of actual system operation, the user queue and the quality of experience (QoE) of user.

In one embodiment, the method for allocating communication network resources, which is capable of mm-wave full duplex network, and comprises: initializing network parameters and collecting queue status information and channel status information; assigning beam to multiple items of user equipment based on beam-closed manner; allocating the beam to the item of user equipment with the smallest value if more than one item of the user equipment is assigned to the same beam; using a rate control to the multiple items of user equipment according to rate closure manner; and determining whether all items of user equipment is assigned to the beam.
