Abstract
Methods and protocols are discussed to address IoT coexistence with existing WLAN devices and protocols. Some embodiments allow for the IoT devices to be located further from the Access Point than other devices, and provide higher power solutions to serve these long range devices. New IoT Frame structures are disclosed to allow for the above.
Claims21
A method for wireless communications by an access point (AP) comprising:
- receiving a first data packet to be transmitted to a station of a first class with a long range requirement;
- inserting the first data packet into a frame for transmission, the frame including bits intended for stations of a second class without the long range requirement;
- and
- transmitting the frame with a portion of the frame including the first data packet being transmitted at a higher power than the remainder of the frame.
1 more element
An access point (AP) comprising:
- an input/output interface configured to receive a first data packet to be transmitted to a station of a first class with a long range requirement;
- a framer configured to insert the first data packet into a frame for transmission, the frame including bits intended for stations of a second class without the long range requirement;
- and
- a radio unit configured to transmit the frame with the portion of the frame including the first data packet being transmitted at a higher power than the remainder of the frame.
1 more element
An access point (AP) comprising:
- an input/output interface configured to receive a first data packet to be transmitted to a station of a first class with a long range requirement;
- a radio portion for transmitting frames;
- a processor;
- a memory including machine readable instructions which when executed by the processor cause the AP:
- insert the first data packet into a frame for transmission, the frame including bits intended for stations of a second class without the long range requirement;
- and
- transmit the frame with the portion of the frame including the first data packet being transmitted at a higher power than the remainder of the frame.
4 more elements
A method for downlink wireless communications by an access point (AP) comprising:
- transmitting a legacy preamble portion, and
- transmitting an OFDMA portion comprising at least one subcarrier RU, and at least one IoT payload, wherein the IoT payload is transmitted with a higher power than data associated with the subcarrier RU.
