Protocol Design and Resource Allocation for LTE-U System Utilizing Licensed and Unlicensed Bands
LTE deployed with both licensed and unlicensed bands (LTE-U) is one of the promising approaches to meet the rapidly growing data demand in wireless networks.In this paper, both throughput and fairness for the LTE-U system are maximized by a multi-objective optimization problem.Then, a log-sum-exp approximation method is developed to convert the mul
