Abstract
In some examples, a wireless device transmits a narrowband downlink frame in a narrowband channel, the narrowband downlink frame comprising a beacon frame that is transmitted periodically.
Claims17
A method of a wireless device, comprising:
- transmitting a narrowband downlink frame in a narrowband channel, the narrowband downlink frame comprising a first beacon that is transmitted periodically, wherein the narrowband channel has a frequency range that is less than and within a frequency range of a wideband channel;
- transmitting, in the narrowband channel, information about a wideband network comprising the wideband channel;
- and
- prior to transmitting the narrowband downlink frame, transmitting further information containing a time period during which stations in range of the wireless device are not to initiate wideband transmissions, the time period being for narrowband communications comprising the transmitting of the first beacon and the information about the wideband network.
1 more element
A first wireless device comprising:
- a communication interface to communicate wirelessly with a second wireless device;
- and
- at least one processor configured to:
- transmit a narrowband downlink frame in a narrowband channel, the narrowband downlink frame comprising a beacon frame that is transmitted periodically, wherein the narrowband channel has a frequency range that is less than and within a frequency range of a wideband channel;
- transmit, in the narrowband channel, information about a wideband network comprising the wideband channel;
- and
- prior to transmitting the narrowband downlink frame, transmit further information containing a time period during which stations in range of the first wireless device are not to initiate wideband transmissions, the time period being for narrowband communications comprising the transmitting of the beacon frame and the information about the wideband network.
4 more elements
A non-transitory storage medium storing instructions that upon execution cause an access point (AP) to:
- transmit a narrowband downlink frame in a narrowband channel, the narrowband downlink frame comprising a first beacon that is transmitted periodically, wherein the narrowband channel has a frequency range that is less than and within a frequency range of a wideband channel;
- transmit, in the narrowband channel, information about a wideband network comprising the wideband channel;
- and
- prior to transmitting the narrowband downlink frame, transmit further information containing a time period during which stations in range of the AP are not to initiate wideband transmissions, the time period being for narrowband communications comprising the transmitting of the first beacon and the information about the wideband network.
