基于用户中断概率的D2D通信干扰协调与资源分配
Outage Probability-based Interference Coordination and Resource Allocation for D2D Communications
摘要
Abstract
The introduction of device-to-device(D2D) communication which communicates with each oth-er by resuing the resource of cellular users in the LTE system will generate mutual interference between cellular users and D2D users. The existing researches on interference coordination and resource allocation require the base station to collect the channel state information( CSI) of each related communication link, which will increase the complexity and signaling overhead of the system. To solve the problem and reduce the mutual interference, an outage probability-based interference coordination and resource allocation method is proposed in this paper,which does not need the CSI. Firstly,in the case of the normal communi-cation of cellular users,the interference from D2D users can be reduced by restricting the distance between D2D users and the base station. Secondly,by traversing the spectrum resources of all the cellular users,al-location resources are chosen for D2D users that can communicate with D2D under the principle of minimi-zing the outage probability of D2D users. Simulation results show that the proposed scheme can significant-ly decrease the average outage probability of D2D users compared with other schemes and also reduce the signaling burden of the base station.关键词
