Problems solved by technology

However, radio waves around the 60GHz band have high atmospheric attenuation and suffer from higher levels of absorption by atmospheric gases, rain, objects, etc. compared to operating in lower frequencies, resulting in higher free space losses

Embodiment Construction

[0025]Aspects of this disclosure can help reduce the time during the sector scanning process. By reducing the length of the sector scanning frame, for example, by compressing or removing one or more fields, the transmission time of each sector scan frame can be reduced. Since the plurality of sector scan frames are typically transmitted during the sector scan, it is mixed. Given a station can perform a sector scanning process with hundreds of stations, thereby reducing the transmission time of each frame or even a few microseconds.

[0026]The various aspects of the present disclosure will be more fully described below with reference to the accompanying drawings. However, the present disclosure can be embodied in many different forms and should not be construed as being limited to any particular structure or functionality exhibited throughout the present disclosure. More specifically, it provides these disclosures to be thorough and complete, and the range of the present disclosure is ...

Abstract

Certain aspects of this disclosure provide techniques that can help reduce sector scan time. In some cases, the technique involves generating frames for transmission during the sector scanning process, each frame including one or more address fields based on at least one of determined by: the transmitter address of the device or the receiver address of the intended recipient of the generated frame, and the one or more address fields have a greater value than at least one of the transmitter address or receiver address Less bits.

Description

[0001]Require priority based on 35U.s.c. §119[0002]This patent application requests US Temporary Patent Application Serial No. 62 / 250, 879, submitted on November 4, 2015, and US Temporary Patent Application Serial No. 62 / 278, 505, submitted on January 14, 2016, and 2016 The interests of the US application No. 15 / 342, 735, submitted on November 3, so it is clearly incorporated herein by reference.Technical field[0003]In summary, the present invention relates to a wireless communication system, and more particularly, the present invention relates to techniques for reducing sector scanning time during beam training in systems that utilize beamforming systems.Background technique[0004]The 60GHz band is from the frequency band, which is characterized by a large amount of bandwidth and large world. Big bandwidth is clearly available wirelessly to send very high capacity information. As a result, a variety of applications can be developed (each application requires transmission of large am...
