Embodiment Construction

[0043] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail by giving specific embodiments and referring to the accompanying drawings.

[0044] No matter in the wireless communication system using the full scheduling technology or in the scheduling and frequency hopping multiplexing system, the users in the cell can use the time-frequency pattern to allocate the occupied time-frequency resources. On the entire time-frequency plane in each TTI, the cell can generate a time-frequency pattern set in a certain way, and the time-frequency patterns in the time-frequency pattern set can occupy the entire time-frequency plane, and the time-frequency patterns in the time-frequency pattern set The smallest unit occupied by the time-frequency pattern in the time domain is an OFDM symbol, and the smallest unit occupied by the time-frequency pattern in the frequency domain is a subcarrie...

Abstract

This invention discloses a method for distributing time frequency resources in a dispatch and FH multiplex system including: A, distributing time frequency pattern set for local areas in the radio communication system and dividing the set into more than one time frequency pattern groups, B, dividing the sub-carriers on the plane of the local time frequency into frequency sub-bands and distributing them to dispatch users in the areas, C, distributing at least one time frequency pattern group to the FH users in the area and distributing the rest to the dispatch users, D, the HF users apply the distributed time frequency pattern transmission data in the pattern set and the dispatch users apply the pattern transmission data distributed for itself and placed in the pattern set in the sub-band, which simplifies the process for distributing time frequency resources.

Description

technical field [0001] The invention relates to a technology for allocating time-frequency resources in a wireless communication system, in particular to a method for allocating time-frequency resources in a scheduling and frequency-hopping complex cycle system. Background technique [0002] Since the 1990s, multi-carrier technology based on Orthogonal Frequency Division Multiplexing (OFDM) has been developed in wireless communication systems. OFDM technology divides the time-frequency resources of the wireless communication system into several orthogonal narrowband sub-channels in the frequency domain, and high-speed data streams are transmitted in parallel on each sub-channel through serial-to-parallel conversion. Due to the narrowband characteristics of the sub-channels, the influence of multipath can be overcome and the orthogonality between the sub-channels can be maintained, thereby ensuring that the interference between users in the cell is very small. [0003] In an...
