Method for scheduling wireless link resource in wireless communication system

Abstract

The invention provides a method for scheduling a wireless link resource in a wireless communication system, comprising the following steps of: 1) obtaining a pre-scheduling data quantity according to the predicted value of the total data quantity of a date which is to be transmitted by the control layer of the wireless link; 2) orderly accumulating the data quantity of each data packet in a logic signal path module to obtain M accumulated values which are closest to the pre-scheduling data quantity corresponding to the logic signal path module; 3) connecting a medium into the control layer to schedule the wireless link resource and obtaining a practical scheduling data quantity; and 4) comparing the pre-scheduling data quantity and the practical scheduling data quantity to judge whether the pre-scheduling data quantity is valid, wherein if the pre-scheduling data quantity is valid, a optimum value is selected from the M accumulated values so as to be taken as the practical scheduling data quantity, and the wireless link control layer connects a series of data packet corresponding to the practical scheduling data quantity into the control layer. The invention can avoid generating data fragments, so as to save storage resources, simplify the design of a transmit terminal, and guarantee the quality of wireless communication.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular, the present invention relates to a wireless link resource scheduling method in a wireless communication system. Background technique [0002] Wireless communication systems include WCDMA, HSDPA, LTE systems, etc. Among them, the LTE system is a new type of wireless communication system that is being standardized. Specifically, LTE is a technical standard formulation plan started by the 3GPP standardization organization in 2004. Its goal is to form a high data rate, low delay and Radio Access Technology with Optimized Packet Transmission Capability, abbreviated as E-UTRAN or LTE. [0003] Scheduling has always been one of the core issues in the research of wireless communication systems. In the LTE system, a media access control (Media Access Control, MAC for short) layer is responsible for performing radio link resource scheduling for a radio link control (...

Problems solved by technology

Since the cutting of data packets and the reassembly of data fragments will generate additional overhead, especially for the data fragments generated by the AM module, it will not only consume a lot of storage resources, but also make the design of the sending end more complicated, and because ARQ confirmation mechanism, it will also consume a certain amount of wireless link resources
