Embodiment Construction

[0050] In conjunction with the accompanying drawings, the specific description of the embodiments of the present invention is provided as follows.

[0051] Combined with the use of each physical resource, coordinate allocation of each physical resource according to actual needs, these resources are mainly SRI, CQI and SRS, in order to allocate tight resources to users who need them most, and improve the utilization efficiency and rationality of physical resources. The implementation is as follows:

[0052] The network side allocates the most suitable SR resources for terminal users by referring to terminal service QoS requirements and uplink data volume requirements;

[0053] The network side allocates the most suitable CQI resource for the terminal user with reference to the channel environment where the terminal is located and the uplink and downlink data volume requirements;

[0054] The network side allocates the most suitable SRS resource for the terminal user by referri...

Abstract

The invention relates to a resource allocation method used for an LTE system. According to the channel environment where terminals are located, physical resources are allocated for terminal users in combination with service Qos requirements and service amount requirements. The resource allocation method includes the steps that a network side refers to the terminal service Qos requirements and uplink data size requirements to allocate SR resources for the terminal users; the network side refers to the channel environment where the terminals are located, the uplink data size requirements and downlink data size requirements to allocate CQI resources for the terminal users; the network side refers to the channel environment where the terminals are located, the uplink data size requirements and whether to adopt a frequency-selective scheduling strategy to allocate SRS resources for the terminal users. The corresponding physical resources are allocated according to terminal actual service requirements and the channel environment, and the use ratio of radio resources of the LTE system is improved to a greater degree.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a method for improving resource utilization by LTE system configuration. Background technique [0002] LTE (Long Term Evolution, long-term evolution) is a long-term evolution of the UMTS technical standard formulated by the 3GPP organization. In the LTE system, the base station needs to perform uplink and downlink scheduling according to information such as the channel environment and buffer status of the terminal. These information depend on the physical resources allocated by the base station to the end users, such as SR (Scheduling Request), CQI (Channel Quality Indication) and SRS (Sounding Reference Signal). Restricted by wireless resources, base station demodulation and scheduling capabilities, these physical resources are very tight to meet the needs of large traffic. [0003] The SR resource includes the SR cycle, whether the SR resource is tight mainly depends on th...
