Abstract :
A wireless resources allocation method for Device-to-Multi-Device (D2MD) communication under the control of base station is proposed. In the premise of ensuring quality of services (QoS) of all D2MD groups, the method can allocate wireless resources for D2MD groups through three steps: mode selection, spectrum allocation and power control. Simulation results show that the method can select the high-spectrum-efficiency mode which reuses the spectrum of cellular users for most D2MD communications, and does not affect cellular communications, the interference to cellular uplink of proposed suboptimal LCH algorithm which allocates cellular spectrums for D2MD groups to reuse can achieve the same level as the optimal algorithm, in addition, the calculating complexity is lower therefore shortening the response time of the base station.
