Distribution method of time frequency resource

Abstract

The method includes steps: each point in sequence x(i) with length L, i=0, 1, 2,apostrophe L-1 is served as a independent variable of k order polynomial; changing coefficient of polynomial to generate multiple sequence f(i) with length L, where k is nonnegative integer; operation in polynomial is carried out in Galois Field GF(Q), where Q=pm, p as a prime number, and m as nonnegative integer; assigning generated sequences to multiple sectors to set of create biased sequences for each sector; it is different in constant terms of polynomial, and identical to other coefficients of coefficients corresponding to sequence assigned to same sector; creating corresponding time - frequency pattern (TFP) unit from biased sequences of the sector; repeating TFP unit with equal interval in frequency domain so as to obtain integrated TFP. The invention solves issue that current techniques have not considered flattened interference between adjacent common frequency sectors.

Description

technical field

[0001] The invention relates to communication technology, in particular to a method for allocating time-frequency resources in a communication system. Background technique

[0002] Geographical areas are used to distinguish wireless communication systems, such as cellular wireless communication systems, and frequency reuse is realized by dividing geographically different communication areas, so as to increase the capacity of the wireless communication system. The cellular radio communication system increases the capacity of the cellular radio communication system by dividing a large service area into many smaller coverage areas to achieve frequency reuse. Each small coverage area may be referred to as a cell. In order to adopt a plan with a frequency reuse factor of 1 and improve the frequency utilization efficiency of the cellular wireless communication system, different cells may use the same frequency. However, if different cells use the same frequency, ...
