OFDMA communications for multiple capability wireless communication devices

摘要

A communication device's processor generates an OFDMA packet that includes different information for different recipient devices. The processor transmits, via a communication interface, different portions of the OFDMA packet via different channels. Initially, the processor transmits a first at least one field of the OFDMA packet intended for a first recipient device via the first channel. Then, the processor transmits a second at least one field of the OFDMA packet intended for the first recipient device via the first channel while simultaneously transmitting at least one other field of the OFDMA packet intended for a second recipient device via a second channel. This staggered transmission of different portions of the OFDMA packet via different channels allows a recipient device to classify different portions of the OFDMA packet and to determine which portions are intended for that recipient device.

主权项

1. A wireless communication device comprising:
a communication interface; and a processor, at least one of the processor or the communication interface configured to:
generate an orthogonal frequency division multiple access (OFDMA) packet that includes a first at least one field intended for a first other wireless communication device and a second at least one field intended for a second other wireless communication device;transmit, via the communication interface, the first at least one field of the OFDMA packet via a first channel; andtransmit, via the communication interface and after the first at least one field of the OFDMA packet has been transmitted via the first channel, the second at least one field of the OFDMA packet via a second channel and simultaneously transmit at least one other field of the OFDMA packet via the first channel.
