Assignee: MARVELL ASIA PTE LTD
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 12:
13. A wireless communication device, comprising:
a wireless network interface device including:
one or more integrated circuit (IC) devices, and
a plurality of radio frequency (RF) radios including at least a first RF radio and a second RF radio, wherein the plurality of RF radios are implemented at least partially on the one or more IC devices;

wherein the one or more IC devices are configured to:
generate a first packet for transmission in a first frequency segment, including generating a first physical layer (PHY) preamble of the first packet to include: i) a first legacy signal field (L-SIG) having first duration information that indicates a first duration of the first packet, and ii) first non-legacy signal field information having first modulation information that indicates a first modulation used in the first packet,
generate a second packet for transmission in a second frequency segment, including generating a second PHY preamble of the second packet to include: i) a second L-SIG having second duration information that indicates a second duration of the second packet, wherein the second duration is different than the first duration, and ii) second non-legacy signal field information having second modulation information that indicates a second modulation used in the second packet, wherein the second modulation is different than the first modulation, and
control the first RF radio and the second RF radio to simultaneously transmit the first packet in the first frequency segment and the second packet in the second frequency segment.
