Restricted frequency band interference cancellation

A method comprising:

• determining a first channel to be used by a device when operating in a first network, wherein the first channel is in a restricted frequency band;
• sampling at least one second channel used by one or more second networks, wherein the at least one second channel is in the restricted frequency band;
• estimating a channel parameter associated with the at least one second channel;
• selecting a first interference cancellation technique or a second interference cancellation technique based at least in part on the estimated channel parameter associated with the at least one second channel, wherein the first interference cancellation technique or the second interference cancellation technique is selected from among a plurality of potential interference cancellation techniques;
• initiating interference cancellation joint in accordance with the selected interference cancellation technique when using the first channel in the first network for a predetermined period of time;
• estimate the channel parameter at the end of the predetermined period of time;
• re-select the first interference cancellation technique or the second interference cancellation technique based on the estimated channel parameter at the end of the predetermined period of time;
• and
• initiate the re-selected first interference cancellation technique or the second interference cancellation technique when using the first channel in the first network.

A device configured to receive transmissions from a first network on a first channel in a restricted frequency band when use of the first channel is permitted in the first network, the device configured to perform interference cancellation for interference caused by at least one second channel used by a second network in the restricted frequency band by:

• sampling the at least one second channel;
• estimating a channel parameter associated with the at least one second channel;
• selecting a first interference cancellation technique or a second interference cancellation technique based at least in part on the estimated channel parameter associated with the at least one second channel, wherein the first interference cancellation technique or the second interference cancellation technique is selected from among a plurality of potential interference cancellation techniques;
• initiating interference cancellation in accordance with the selected interference cancellation technique when using the first channel for a predetermined period of time;
• estimating the channel parameter at the end of the predetermined period of time;
• re-selecting the first interference cancellation technique or the second interference cancellation technique based on the estimated channel parameter at the end of the predetermined period of time;
• and
• initiating the re-selected first interference cancellation technique or the second interference cancellation technique when using the first channel in the first network.
