System and method for channel selection to reduce impact to an existing network

An apparatus, comprising:

• means for accessing a list of channels for cellular communication on an unlicensed band, the list having the channels in an order of priority for reducing interference to non-cellular communication on the unlicensed band;
• means for determining an interference criteria for a received signal, the interference criteria corresponding to a metric that combines a received signal strength indicator (RSSI) and a duty cycle of the received signal;
• means for selecting, based on the order of priority, a first channel from the list of channels that has not been previously selected and has a highest priority for reducing interference to non-cellular communication on the unlicensed band;
• mean for determining whether the first channel that satisfies the interference criteria;
• means for selecting the first channel for cellular communication in the unlicensed band to further reduce the interference to non-cellular communication in the unlicensed band when the first channel satisfies the interference criteria;
• means for selecting, based on the order of priority, a second channel from the list of channels that has not been previously selected and that has the highest priority for reducing interference to non-cellular communication on the unlicensed band, the second channel selected to determine whether the second channel satisfies the interference criteria when the first channel does not satisfy the interference criteria;
• means for identifying a best suited channel from the list on which the cellular communication results in a least amount of interference to non-cellular communication on the unlicensed band, in response to none of the channels in the list satisfying the interference criteria without going through, in the order of priority, each channel in the list again;
• and
• means for selecting the best suited channel for cellular communication in the unlicensed band to further reduce the interference to non-cellular communication in the unlicensed band.

An apparatus, comprising:

• at least one radio frequency (RF) transceiver;
• at least one processor coupled to the at least one RF transceiver and configured to:
• access a list of channels for cellular communication on an unlicensed band, the list having the channels in an order of priority for reducing interference to non-cellular communication on the unlicensed band;
• determine an interference criteria for a received signal, the interference criteria corresponding to a metric that combines a received signal strength indicator (RSSI) and a duty cycle of the received signal;
• select, based on the order of priority, a first channel from the list of channels that has not been previously selected and that has a highest priority for reducing interference to non-cellular communication on the unlicensed band;
• determine whether the first channel satisfies the interference criteria;
• when the first channel satisfies the interference criteria, select the first channel for cellular communication in the unlicensed band to further reduce the interference to non-cellular communication in the unlicensed band;
• when the first channel does not satisfy the interference criteria, select, based on the order of priority, a second channel from the list of channels that has not been previously selected and that has the highest priority for reducing interference to non-cellular communication on the unlicensed band, the second unselected channel selected to determine whether the second channel satisfies the interference criteria without going through, in the order of priority, each channel in the list again;
• identify a best suited channel from the list on which the cellular communication results in a least amount of interference to non-cellular communication on the unlicensed band, in response to none of the channels in the list satisfying the interference criteria;
• select the best suited channel for cellular communication in the unlicensed band to further reduce the interference to non-cellular communication in the unlicensed band;
• and
• a memory coupled to the at least one processor for storing data.

A non-transitory computer-readable medium storing computer executable code for wireless communication, comprising code to:

• access a list of channels for cellular communication on an unlicensed band, the list having the channels in an order of priority for reducing interference to non-cellular communication on the unlicensed band;
• determine an interference criteria for a received signal, the interference criteria corresponding to a metric that combines a received signal strength indicator (RSSI) and a duty cycle of the received signal;
• select, based on the order of priority, a first channel from the list of channels that has not been previously selected and that has a highest priority for reducing interference to non-cellular communication on the unlicensed band;
• and
• determine whether the first channel satisfies the interference criteria;
• when the first channel satisfies the interference criteria, select the first channel for cellular communication in the unlicensed band to further reduce the interference to non-cellular communication in the unlicensed band;
• when the first channel does not satisfy the interference criteria, select, based on the order of priority, a second channel from the list of channels that has not been previously selected and that has the highest priority for reducing interference to non-cellular communication on the unlicensed band, the second unselected channel selected to determine whether the second channel satisfies the interference criteria;
• identify a best suited channel from the list on which the cellular communication results in a least amount of interference to non-cellular communication on the unlicensed hand, in response to none of the channels in the list satisfying the interference criteria without going through, in the order of priority, each channel in the list again;
• and
• select the best suited channel for cellular communication in the unlicensed band to further reduce the interference to non-cellular communication in the unlicensed band.
