Speed frame exchange within single user, multiple user, multiple access, and/or MIMO wireless communications

摘要

A signaling protocol allows for speed frame exchange between different wireless communication devices within single user, multiple user, multiple access, and/or MIMO wireless communication system. A listening wireless communication device analyzes state of speed frame indicator bits within frames transmitted from a first other wireless communication device to determine the entire radio frame exchanges between that first other wireless communication device and a second other wireless communication device. The second other wireless communication device may be a hidden node relative to the listening wireless communication device such that all or less than all transmissions from the hidden node are received by the listening device. The listening wireless communication device determines the status of the communication medium (e.g., the air in the context of a wireless communication system), so that it can transmit successfully without interfering with any ongoing communications between the first and second other wireless communication devices.

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:
detect one or more frames transmitted from a first other wireless communication device and directed to a second other wireless communication device, wherein the second other wireless communication device is out of range of communication with the wireless communication device;interpret the one or more frames to determine characteristics of communication between the first and the second other wireless communication devices;determine when the second other wireless communication device is likely transmitting based on the characteristics of communication; anddetermine that a communication channel is unavailable when the second other wireless communication device is determined to be likely transmitting.
