A proposal for Carrier Sense using Control Channel in LTE Systems - Toward Spectrum Sharing between Different Operators

摘要

In spectrum sharing, Carrier Sense (CS) to detect other radio entities is very important in situations where coordination based on wired network is not easy for different operators or many deployments. This paper proposes a novel CS for fine sensing toward spectrum sharing in LTE systems among different operators by utilizing a prior knowledge of a control channel for resource scheduling. Numerical experiments show that the proposed method can achieve significant detection performances in cases of various bandwidth for LTE system.
