摘要

In millimetre cellular wave (mmWave) networks, beamforming is an enabling technology. Although the beams in mmWave network are directional and in narrow shapes, there may also exist overlapped areas. To enable the multi-user simultaneous transmissions within the same time slot, the multi-beams subchannel assignment problem is formulated as a non-linear integer programming problem. To combat the complexity, a UE-group based subchannel assignment algorithm is proposed in this paper. According to the locations of the UEs’ in the overlapped areas, or the non-overlapped areas, the subchannels are assigned to the UE/UEs, where the beam spatial reuse gain and subchannel multi-user diversity gain are both exploited. Simulation results evaluate the performance of the proposed algorithm, and reveal the relationships of the beam spatial reuse gain and subchannel multi-user diversity gain, with the UE numbers and the downlink traffic load of each UE, respectively.
