Method for Allocating Time-Frequency Resources in a Communication System
First Claim
1. A method for allocating time-frequency resources in a communication system, applicable to wireless communication systems using Orthogonal Frequency Division Multiplexing (OFDM) technology, comprising:
- configuring at least one time-frequency pattern for allocating time-frequency resources in a communication system;
extracting segment time-frequency patterns from the time-frequency pattern by a cyclic slide window with one or more kinds of widths;
forming multiple different segment time-frequency pattern sets from the obtained segment time-frequency patterns, wherein the segment time-frequency patterns in the same segment time-frequency pattern set are orthogonal to each other;
randomly selecting, for each Transmission Time Interval (TTI), at least one segment time-frequency pattern set; and
allocating the segment time-frequency patterns in the selected segment time-frequency pattern set to at least one user and/or traffic channel in the TTI.

Abstract
A method for allocating time-frequency resources in a communication system is disclosed in an embodiment of the present invention. The method includes: configuring at least one time-frequency pattern for allocating time-frequency resources in a communication system; extracting segment time-frequency patterns from the time-frequency pattern by a cyclic slide window with one or more kinds of widths; forming multiple different segment time-frequency pattern sets according to the obtained segment time-frequency patterns, wherein the segment time-frequency patterns in the same set are orthogonal to each other; randomly selecting, in each Transmission Time Interval (TTI), at least one segment time-frequency pattern set; and allocating the segment time-frequency patterns in the selected segment time-frequency pattern set to at least one user and/or traffic channel in the TTI. The method acquires no resource planning, ensures little intra-cell interference while randomizing inter-cell interference.
