Techniques for fast delivery of radio information

摘要

A transmitting wireless device provides channel access information to a receiving wireless device for the receiving wireless device to make a determination of when to transmit and what transmissions parameters to use for the transmission. The channel access information may be used differently by wireless devices operating in a basic service set and an overlapping basic service set. Channel access information may include fields indicative of transmission power used, signal to noise ratio headroom available, and so on. Channel access information may be generated and transmitted at the PHY layer of an implementation, thus providing a fast delivery to the receiving wireless device.

主权项

1. A method of wireless communication, comprising:
performing, by a wireless communication device, an interference measurement of a wireless transmission medium; and performing a current wireless transmission that includes channel assessment information, wherein the information includes one or both of: (a) a transmit power used for the current wireless transmission; (b) an operating value indicative of whether the wireless communication device is operating in a basic service set or an overlapped basic service set; and (c) an estimation of Signal to Interference and Noise Ratio (SINR) over an interference level based on at least the interference measurement, the operating value, and a threshold value for a clear channel assessment to indicate a channel quality that allows a new transmission to overlap at least partially with an existing transmission.
