Embodiment Construction

[0045] In conjunction with the accompanying drawings, the specific description of the embodiments of the present invention is provided as follows.

[0046] 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 efficiency and rationality of physical resource utilization. The implementation is as follows:

[0047] The network side allocates the most suitable SR resources for terminal users by referring to terminal service QoS requirements and uplink data volume requirements;

[0048] 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;

[0049] The network side allocates the most suitable SRS resource for the terminal user by referrin...

Abstract

A resource allocation method for LTE systems, which allocates physical resources to end users based on the channel environment where the terminal is located, combined with business Qos requirements and business volume requirements, including allocating physical resources to end users on the network side with reference to terminal business Qos requirements and uplink data volume requirements. SR resources; the network side allocates CQI resources to end users with reference to the channel environment and uplink and downlink data volume requirements of the terminal; the network side allocates SRS resources to end users with reference to the channel environment and uplink data volume requirements of the terminal and whether to adopt the frequency selective scheduling strategy. . This method configures corresponding physical resources based on the actual business requirements of the terminal and the channel environment, and improves the wireless resource utilization efficiency of the LTE system to a large extent.

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 terminal 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 ...
