Methods for LTE channel selection in unlicensed bands

An apparatus, comprising:

• means for operating in a first mode using a first radio access technology (RAT1), wherein operating in the first mode comprises communicating on an unlicensed band;
• means for collecting interference measurements for interference to or from at least one mobile device while in the first mode;
• means for building a database from the collected interference measurements, the database comprising information regarding interference levels experienced by the network entity for LTE communication on channels of the unlicensed band, wherein collecting the interference measurements comprises directly making the interference measurements;
• means for switching to a second mode and using a second radio access technology (RAT2);
• and
• means for using the interference measurements from the first mode to reduce interference caused or experienced by the network entity in the second mode by selecting a channel in the unlicensed band for communication from a prioritized list of channels, wherein each channel in the prioritized list of channels is checked in order of priority and a first channel from the prioritized list of channels that satisfies an interference criteria based on a received signal strength indicator (RSSI) metric and a duty cycle metric being less than a threshold is selected.

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:
• operate in a first mode using a first radio access technology (RAT1), wherein operating in the first mode comprises communicating on an unlicensed band;
• collect interference measurements for interference to or from at least one mobile device while in the first mode;
• build a database from the collected interference measurements, the database comprising information regarding interference levels experienced by the network entity for Wi-Fi communication on channels of the unlicensed band, wherein collecting the interference measurements comprises directly making the interference measurements;
• switch to a second mode and using a second radio access technology (RAT2);
• and
• use the interference measurements from the first mode to reduce interference caused or experienced by the network entity in the second mode by selecting a channel in the unlicensed band for communication from a prioritized list of channels, wherein each channel in the prioritized list of channels is checked in order of priority and a first channel from the prioritized list of channels that satisfies an interference criteria based on a received signal strength indicator (RSSI) metric and a duty cycle metric being less than a threshold is selected;
• and
• a memory coupled to the at least one processor for storing data.
