Impact of Channelization on Two Power Allocation Schemes at 6 GHz Band

In this paper we study the impact of channel center frequency and bandwidth of interferer and victim links on maximum permissible power for two power allocation schemes, namely channel-based and PSD-based. The three different channelization scenarios are considered in the comparison, i.e., 1) when interferer channel is inside the victim channel, 2) when the two channels partially overlap, and 3) when the victim channel is inside the interferer channel. The performance evaluation results show that in the first scenario both power allocation schemes show the same result. In case of the second scenario the difference between two methods mainly depends on the overlapping area of interferer and victim channels. Finally, in the third scenario the difference in power allocation depends on the bandwidth of the victim channel. In addition, the number of power quantization levels is directly proportional to the power difference between two schemes.
