Abstract:
1. A method, comprising: providing data transmission parameters of an orthogonal frequency division multiplexing-based cellular network, said parameters including at least two values of a signal-to-interference-and-noise ratio and an associated achievable data throughput for at least one antenna of said network, and at least one required data throughput for at least one user; defining a transformed signal-to-interference-and-noise ratio based on said provided signal-to-interference-and-noise ratio; determining, using a processor, at least two constant coefficients defining a linear function of said transformed signal-to-interference-and-noise ratio, said linear function describing an approximated channel activity for a single user in uplink or downlink for the at least one antenna of said network, said approximated channel activity being defined as a ratio of each of the required data throughput to the achievable data throughput; determining a total channel activity of the at least one antenna for uplink and/or downlink from said single user approximated channel activity; and checking whether said determined total channel activity of the at least one antenna for uplink and/or downlink has a value of less than 1.
