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 to generate a first frame including a PHY layer header comprising a first PHY layer sub-header and a second PHY layer sub-header, the first PHY layer sub-header including an indication of a channel to be used to communicate data and the second PHY layer sub-header including an indication of one or more multiple-input multiple-output (MIMO) training sequences, the PHY layer header including a first bit that indicates the presence of the first PHY layer sub-header and a second bit that indicates the presence of the second PHY layer sub-header; and a transmitter operably coupled to the circuitry and configured to cause the circuitry to transmit the first frame, the first frame transmitted using a first millimeter wave channel, the first millimeter wave channel different from the channel.
