Abstract With the rapid development of technology and the popularity of mobile devices, the demand of transmission data rate has been increasing.The 3GPP proposed the use of 5GHz unlicensed band to extend LTE in order to meet the needs of a large number of users.While the traditional packet scheduling algorithms are not flexible for the aggregation of the unlicensed spectrum, this paper proposes an AHP distribution algorithm for allocating resource to users.Not only the channel quality of each resource block for users, but also whether the users are GBR users and proportion of LTE and LTE-U users are considered.The results of the simulation will show that the proposed method can flexibly allocate spectrum resourcesand maintains the satisfaction of GBR users.
