In this paper, we consider multiple channels and wireless nodes with multiple\ntransceivers. Each node assigns one transmitter at each available channel. For\neach assigned transmitter the node decides the power level and data rate of\ntransmission in a distributed fashion, such that certain Quality of Service\n(QoS) demands for the wireless node are satisfied. More specifically, we\ninvestigate the case in which the average SINR over all channels for each\ncommunication pair is kept above a certain threshold. A joint distributed power\nand rate control algorithm for each transmitter is proposed that dynamically\nadjusts the data rate to meet a target SINR at each channel, and to update the\npower levels allowing for variable desired SINRs. The algorithm is fully\ndistributed and requires only local interference measurements. The performance\nof the proposed algorithm is shown through illustrative examples.\n
