Abstract:
1. A resource allocation method in an orthogonal frequency division multiplexing system, the method comprising: acquiring, by a base station, channel state information (CSI) of a current scheduling timeslot; obtaining a compensation factor according to the CSI and a preset packet error ratio, wherein the compensation factor is a value corresponding to the preset packet error ratio in an inverse cumulative distribution function of a non-central chi-square random variable and a non-central parameter; replacing the CSI with the compensation factor, and determining a functional relationship between rate and power of sending data by the base station if a packet error ratio of the base station is less than or equal to the preset packet error ratio; and determining, according to the functional relationship and a generalized dynamic back pressure algorithm, the rate and total power of sending data by the base station, so as to minimize the total power of the base station, wherein the generalized dynamic back pressure algorithm is a back pressure algorithm comprising a delay factor and a power-delay trade-off parameter.
