The embodiment of the invention provides a radio resource allocation method and device and relates to the technical field of communication. The quality of experience of a user can be effectively improved. The method comprises the steps that a terminal receives a QoE (Quality of Experience) weight model sent by an analysis server; a first QoE parameter of the terminal is obtained, wherein the firstQoE parameter of the terminal comprises a first QoE parameter value of each application in target applications, and the first QoE parameter is a real-time QoE parameter; the terminal determines an influence weight of the first QoE parameter of the terminal for the QoE according to the first QoE parameter of the terminal and the QoE weight model; and the terminal sends the influence weight of thefirst QoE parameter of the terminal for the QoE to a radio resource manager, so the radio resource manager allocates radio resources to the terminal according to the influence weight of the first QoEparameter of the terminal for the QoE, wherein the QoE weight model is the model representing a relationship between the QoE parameter of the terminal and the influence weight of the QoE parameter ofthe terminal on the QoE.
