Patent ID: 7733828

Claim:
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, wherein the at least one time-frequency pattern is divided into at least one set, the time-frequency patterns in the same set are orthogonal to each other and the time-frequency patterns in different sets have at most one hit, the at least one time-frequency pattern configured for allocating time-frequency resources in a communication system comprises all elements from a time-frequency pattern cluster having the maximum number of time-frequency pattern sets and satisfies two-dimensional correlation property; extracting segment time-frequency patterns from the time-frequency pattern by a cyclic sliding window with one width or by more than one cyclic sliding window; forming multiple 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.
