Embodiment Construction

[0040] A user-oriented resource allocation method in an SC-FDMA system according to the present invention will be described in detail below with reference to the drawings and embodiments.

[0041] In the user-oriented resource allocation method in a SC-FDMA system of the present invention, by reasonably defining the system satisfaction utility function, the contribution of users who can obtain satisfactory service to the utility function is set as its MOS score, and users who cannot obtain satisfactory service The contribution to the utility function is set to 0, so as to ensure that the served users are all users who can obtain satisfactory services, and on this basis, the average MOS score of each user is maximized to ensure that the system can be as good as possible to the greatest extent. Provide satisfactory service to many users. The specific implementation steps are as follows:

[0042] Step 1): According to the number of available sub-channels in the SC-FDMA uplink sy...

Abstract

The invention provides a user-oriented resource distribution method in an SC-FDMA system. According to the method, a system satisfaction utility function is reasonably defined; the contributions of users capable of obtaining satisfied services to the utility function are set as MOS values; the contributions of users incapable of obtaining satisfied services to the utility function are set as 0; therefore, the served users are ensured to be the users capable of obtaining satisfied services; on this basis, maximization of the system satisfaction utility function is taken as an optimization object; under the condition of limited system resources, how to distribute sub-channels to the users is determined; therefore, the service experience qualities of the SC-FDMA system for the users are improved, and the satisfaction degree of the services for the users is maximized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a user-oriented resource allocation method in an SC-FDMA system. Background technique [0002] With the rapid expansion of mobile Internet services, wireless resources are still scarce and precious in the 4G LTE system. As we all know, SC-FDMA is the uplink transmission technology of 4G LTE system. Therefore, how to effectively utilize wireless resources in SC-FDMA systems to meet various service requirements is still a topic worth studying, and it is also a research hotspot in recent years. [0003] The traditional method is aimed at improving the service quality (quality of service, QoS), such as increasing throughput and reducing delay. However, QoS cannot reflect the actual experience of end users on services. On the other hand, the quality of experience (QoE) can more closely reflect the subjective feeling of the user. Therefore, it is necessary to consider ...
