US 2023/0056736 A1 · CLEAR CHANNEL ASSESSMENT (CCA) ENABLED NARROWBAND (NB) COMMUNICATIONS

Abstract

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.

Dependent claims

A wireless communication device for narrowband (NB) communications, comprising:

a processing system configured to:
perform a clear channel assessment (CCA) to assess whether a first NB channel is clear;
and
an interface configured to:
associate with a first NB channel;
and
transmit 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.
