Using self-degradation in dynamic spectrum allocation

摘要

A communication node of a multi-node communication network may include a communication interface and a controller communicatively coupled to the communication interface. The controller may be configured to: transmit one or more data packets over an in-use channel to one or more additional communication nodes of the multi-node communication network; determine an in-use channel quality indicator (CQI) value (CQI_in-use) of the in-use channel; determine a self-degradation value (SDV) indicative of channel quality degradation attributable to the multi-node communication network; determine a candidate CQI value (CQI_candidate) of an identified candidate channel different from the in-use channel; determine a first CQI difference value (CQI_1diff); transmit one or more data packets over the in-use channel if CQI_1diff does not exceed a CQI threshold value (CQI_thresh); and transmit one or more data packets over the candidate channel if CQI_1diff exceeds CQI_thresh.
