Abstract

A network controller may schedule directional communications between two devices in its own network in such a way as to avoid potential interference from anticipated transmissions from another device. In some instances, the network controller may be one of the two devices using the directional communications. The timing of the anticipated transmissions may be determined by the network controller based on its own observations, or it may be informed of that timing in a transmission from a device in its own network. A possible format is given for transmitting that information to the network controller.

Description

technical field [0001] The present invention relates to traffic limitation in millimeter wave wireless networks. Background technique [0002] Wireless communication networks operating at frequencies at or above tens of gigahertz (corresponding wavelengths of a few millimeters or less) typically have very short signal ranges and are therefore mainly used for personal area networks (PANs). Interference between adjacent PANs can be a significant problem when many PANs are placed closely together, such as in an office environment. Directional communication is often used to alleviate this problem, but common methods of scheduling interference-free wireless communication (such as RTS / CTS techniques) are not well suited for networks using directional communication. Specifically, when a STA requests a certain channel time from its NC, the NC may not be aware of the repeated interfering signal from a neighboring PAN, and may schedule a time for the STA to overlap with that interfer...
