Abstract
A wireless transmit/receive unit (WTRU) or access point (AP) may generate a protocol data unit (PDU) of a first 802.11 protocol and a preamble and data of a second 802.11 protocol. The preamble and data of the second 802.11 protocol may be arranged on resources of the PDU of the first 802.11 protocol with shaping sequences for concurrent transmission.
Claims16
A wireless transmit/receive unit (WTRU) comprising:
- a processor configured to generate a protocol data unit (PDU) including a first preamble, a first 802.11 protocol preamble, and first 802.11 protocol data on one or more resource units (RUs) of a first 802.11 protocol and to generate a second 802.11 protocol preamble and second 802.11 protocol data on the one or more RUs, wherein the second 802.11 protocol preamble and the second 802.11 protocol data overlap in time with the first 802.11 protocol preamble;
- and
- a transmitter configured to transmit the second 802.11 protocol preamble and the second 802.11 protocol data concurrently with the first preamble, the first 802.11 protocol preamble, and the first 802.11 protocol data, wherein one or more shaping sequences in a frequency domain are utilized for one or more on-off keying (OOK) symbols to transmit the second 802.11 protocol preamble and the second 802.11 protocol data.
A method performed by a wireless transmit/receive unit (WTRU), the method comprising:
- generating, by the WTRU, a protocol data unit (PDU) including a first preamble, a first 802.11 protocol preamble, and first 802.11 protocol data on one or more resource units (RUs) of a first 802.11 protocol and to generate a second 802.11 protocol preamble and second 802.11 protocol data on the one or more RUs, wherein the second 802.11 protocol preamble and the second 802.11 protocol data overlap in time with the first 802.11 protocol preamble;
- and
- transmitting, by the WTRU, the second 802.11 protocol preamble and the second 802.11 protocol data concurrently with the first preamble, the first 802.11 protocol preamble, and the first 802.11 protocol data, wherein one or more shaping sequences in a frequency domain are utilized for one or more on-off keying (OOK) symbols to transmit the second 802.11 protocol preamble and the second 802.11 protocol data.
