Exploiting Student-Project Allocation Matching for Spectrum Sharing in LTE-Unlicensed

LTE, as the advanced mobile telecommunication technology, is serving heavy mobile broadband traffic nowadays. Motivated by the potential boost in performance of LTE utilizing the unlicensed spectrum, significant efforts have been devoted into the commonly referred LTE-Unlicensed technique. In this work, we investigate the carrier aggregation of licensed and unlicensed spectrum by deploying micro-cell base stations, which have access to the unlicensed spectrum, to provide cellular users a more reliable and efficient transmission. We tackle the unlicensed resource allocation problem by modeling it as a student-project allocation matching game. In addition, a post-matching procedure of resource re-allocation is introduced to guarantee unlicensed users' quality of service (QoS), as well as the system-wide stability. The simulation evaluation shows the effectiveness and efficiency of our proposed matching-based approach.CPCI-S(ISTP)ygu6@uh.edu; yzhang82@uh.edu; lincai@iit.edu; mpan2@uh.edu; lingyang.song@pku.edu.cn; zhan2@uh.ed
