MULTIPLE ACCESS SYSTEM, METHOD AND DEVICE BASED ON ORTHOGONAL FREQUENCY-DIVISION MULTIPLEXING

摘要

Embodiments of the present invention provide a multiple access system, method and device based on orthogonal frequency-division multiplexing. The multiple access system based on orthogonal frequency-division multiplexing comprises a transmitting end and a receiving end. The transmitting end determines one or more resource blocks that support service data transmission of a specific user terminal, and maps service data and a resource home identification of the specific user terminal to the one or more resource blocks to generate multi-carrier signals modulated by multiple sub-carriers, the resource home identification being mapped in a control resource area in a specific resource block. The receiving end identifies the resource block belonging to the specific user terminal according to the resource home identification mapped in the control resource area in the specific resource block, and acquires the service data from a data resource area in the resource block of the specific user terminal.
