MIMO AND BANDWIDTH SIGNALING IN MILLIMETER-WAVE SYSTEMS

摘要

Techniques to enable dynamic bandwidth management at the physical layer level while maintaining backwards compatibility in wireless systems is provided. Furthermore, techniques for reducing the occurrence of exposed nodes are provided. A transmitter may transmit a frame including an indication that a PHY layer sub-header defining a bandwidth associated with a channel is present. Furthermore, the transmitter may transmit a third frame after receiving a second frame from a receiver to indicate to legacy stations that the TXOP was successful.

主权项

1. An apparatus for a station in a wireless network comprising:
circuitry; and a transmitter operably coupled to the circuitry and configured to cause the circuitry to transmit a first frame, the frame transmitted using a first millimeter wave channel and including a PHY layer header and a PHY layer sub-header, the PHY layer sub-header including an indication of a second channel to be used to communicate data, the first channel different from the second channel.
