Embodiment Construction

[0041] The user-oriented resource allocation method in the SC-FDMA system according to the present invention will be described in detail below with reference to the drawings and embodiments.

[0042] The user-oriented resource allocation method in the SC-FDMA system described in the present invention ensures that the SC-FDMA system can provide satisfactory services for the most users by introducing the goal of maximizing the number of satisfied service users. The specific implementation steps are as follows:

[0043] Step 1): according to the number of available sub-channels in the SC-FDMA uplink system, determine the sub-channel mode allocation matrix, and this matrix satisfies that the sub-channels allocated to the same user in the SC-FDMA system remain continuous;

[0044] Step 2): adopt the mapping relationship between the MOS score and the rate, and estimate the MOS score obtained by each user under each allocation mode in the sub-channel allocation mode matrix;

[0045]...

Abstract

The invention provides a user-oriented resource distribution method in an SC-FDMA system. According to the method, the optimal object is to maximize the number of users obtaining satisfactory service in the system, and through modeling the number of the users obtaining satisfactory service in the system, how to distribute sub-carriers to the users is determined under the condition of limited system resources, and thereby the business experience quality of the user to the SC-FDMA system is enhanced, and the service satisfaction of the user is maximized.

Description

technical field [0001] The present 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 4GLTE system. As we all know, SC-FDMA is an uplink transmission technology of the 4G LTE system. Therefore, how to effectively utilize the wireless resources in the SC-FDMA system to meet various service requirements is still a subject worthy of study, and also a research hotspot in recent years. [0003] The traditional method is aimed at improving the quality of service (QoS), such as increasing throughput and reducing delay. However, QoS cannot reflect the end user's actual experience of the service. On the other hand, quality of experience (QoE) can more closely reflect the subjective feelings of users. Therefore, it is necessary to consider the user...
