Problems solved by technology

[0006] Since different service types have different sensitivity to resources, that is, different services have different utility functions, and MOS score is a relatively rough measure of user QoE, so this may lead to waste of resources in limited improvement. MOS score that is difficult for users to feel

Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. This embodiment is carried out on the premise of the technical solution of the present invention, and the detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.

[0052] The present invention specifically takes VoIP, IPTV, and Filedown (FD) three multimedia services as examples. Firstly, the relationship between QoE quality and transmission rate of the three services are modeled respectively, as shown in equations (9)-(11):

[0053] η IPTV = a 1 + a 2 FR + ...

Abstract

The invention relates to a resource allocation scheme in the field of wireless communication, and specifically relates to a resource allocation scheme which can ensure the joint optimization of power and carriers of user experience quality of a terminal under a multi-user and multi-service scene in an orthogonal frequency division multiplexing (OFDM) system, which belongs to the technical field of communication. According to the resource allocation scheme, a gradual resource allocation algorithm (GRAA) is adopted for calculating sub-carrier and power allocation and allocating appropriate number of carriers and power for each user according to different sensitivities of demands of various services on resources and different channel states in which the users are, thereby ensuring QoE (quality of experience) of each user and simultaneously saving resources to the greatest extent.

Description

Technical field: [0001] The present invention relates to a resource allocation scheme in the field of wireless communication, in particular to an Orthogonal Frequency Division Multiplexing (OFDM) system, in a multi-user multi-service scenario, to ensure the quality of user experience of a terminal A resource allocation scheme for joint optimization of power and carrier wave belongs to the field of communication technology. Background technique: [0002] With the development of wireless network and smart phone technology, multimedia services (eg, video streaming media, online games, download services, etc.) have received more and more attention and research. With the rise of multimedia services, the increase in the amount of service data also puts forward higher requirements on the network transmission rate. Although wireless standards such as LTE and LTE-A continue to increase the peak rate of the downlink channel, providing high-quality services for a large number of multi...
