Abstract:
In order to improve the quality of communication between electronic devices, one or more sub-channels used during communication between the electronic devices are dynamically modified based on one or more performance metrics and allowed transmit powers of the sub-channels. In particular, when the one or more performance metrics indicate that a distance between the electronic devices falls within a mid-range of distances, the one or more performance metrics may be used to guide selective changes to the sub-channels used during the communication based on the allowed transmit powers. The changes to the sub-channels used during the communication may increase, decrease or leave the total bandwidth unchanged. Moreover, by changing the sub-channels used during the communication, the allowed transmit power(s) of the sub-channel(s) used may be increased, which may improve the performance during the communication.
