Abstract

One or more coordinating devices may be utilized to control high speed data transmission among a plurality of wireless devices utilizing 60 GHz for high speed data transmission. Control messages may be sent and / or received between each of the plurality of wireless devices and the one or more coordinating devices utilizing low rate control connections via available secondary physical layers. The secondary physical layers may comprise Bluetooth, 802.11, and / or UWB physical layers. The controlling may comprise time coordination, frequency coordination, and / or spatial coordination that may enable the wireless devices to align and / or position directional antenna that may be utilized to perform the 60 GHz high speed data transmission. The wireless devices may utilize the low rate control connections to communicate reporting messages to the one or more coordinating devices. The reporting information may enable the one or more coordinating devices to manage available resources in the plurality of wireless devices.

Description

technical field [0001] The present invention relates to data transmission in wireless devices, and more particularly, to a method and system for a low-rate MAC / PHY for 60GHz transmission. Background technique [0002] In recent years, the field of wireless communication has witnessed remarkable development. In today's world, most people use wireless devices continuously every day for a variety of purposes, such as business and personal. Society has also become wireless. The introduction of a large number of wireless technology solutions has greatly changed daily life. [0003] For example, wireless personal area networks (WPANs) are widely used because they provide flexible and convenient connections. By providing short-range wireless connections, WPAN systems can often replace cumbersome cables and / or wiring used to connect peripherals and / or mobile terminals. This short-range wireless connection will be limited to a very small space (typically, within a range of 10 met...
