Claim 12:
13. A method performed by an apparatus of a wireless communication device for narrowband (NB) communications, comprising:
associating with a first NB channel of a plurality of NB channels;
performing a plurality of clear channel assessments (CCAs) to assess whether a plurality of NB channels are not clear, each of the plurality of CCAs being associated with a respective timer;
identifying whether at least a first quantity of CCAs of the plurality of CCAs causes the wireless communication device to assess that at least one of the plurality of NB channels is not clear based at least in part on whether each of at least a second quantity of timers associated with the at least the first quantity of CCAs is not expired, wherein the first quantity is the same as the second quantity; and
transmitting on the first NB channel when the first NB channel is clear,
wherein:
NB communications include Bluetooth® (BT) communications;
the first NB channel is a first BT channel; and
a first frequency spectrum includes the first BT channel, the first frequency spectrum being used for wireless local area network (WLAN) communications.
