Abstract

See full text

This disclosure provides systems, methods and apparatus for clear channel assessment (CCA) enabled narrowband (NB) communications. In some implementations, a device is configured to associate with an NB channel (such as a Bluetooth channel), perform a CCA to assess whether the NB channel is clear, and transmit on the NB channel when clear. If the NB channel is not clear, the device may prevent transmitting on the NB channel. The device may prevent avoiding the NB channel after the first time that the NB channel is not clear. If the NB channel remains not clear (such as over a number of CCAs for the NB channel), the device may avoid the NB channel by removing the NB channel for FH for an amount of time. In some implementations, the device may be configured to perform frame based equipment (FBE) CCAs for one or more NB channels.
