Abstract
A method and apparatus are described that facilitate reducing intra-cell interference and meanwhile randomizing inter-cell interference without cell planning. Segment time-frequency patterns can be obtained to form multiple different segment time-frequency pattern sets where the segment time-frequency patterns in one time-frequency pattern set are orthogonal to each other. Randomly select at least one segment time-frequency pattern set in each TTI. Within each TTI, at least one user and/or traffic channel in one cell may be randomly assigned to at least one segment time-frequency pattern of the segment time-frequency pattern set.

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.
