Embodiment Construction

[0022] The construction, manufacture and use of the preferred embodiment are discussed in detail below. It should be appreciated, however, that the present invention provides many applicable inventive concepts that can be embodied in a wide variety of specific contexts. The specific embodiments discussed are merely illustrative of specific ways to make and use the invention, and do not limit the scope of the invention.

[0023] Listen-before-talk (LBT) rules in unlicensed spectrum, such as 5G Unlicensed (5G-U) spectrum, require devices to check for potential occupants of the unlicensed spectrum, i.e., “listen”, before transmitting, i.e. “speaking”. ". LBT is a mandatory requirement to use unlicensed spectrum in some areas. Furthermore, LBT has been adopted as a working hypothesis for the Licensed Spectrum Assisted Access (LAA) research project in LTE-A Release 13. When the number of mobile wireless users increases, LBT-compatible access methods may be unfair to WiFi users. ...

Abstract

The invention discloses a method and system for adaptive channel access in unlicensed spectrum. A method and a device for adaptive channel access are disclosed. In an embodiment includes adaptively adjusting, by a small base station (SBS), access parameters for small cells to ensure quality of service (QoS) to mobile wireless users while minimizing collision probability for WiFi users.

Description

[0001] This application claims the benefit of U.S. Patent Application Serial No. 14 / 924,640, filed October 27, 2015, and entitled "Method and System for Adaptive Channel Access in Unlicensed Spectrum," which claims March 31, 2015 US Provisional Patent Application No. 62 / 140,972, entitled "Methods and Systems for Adaptive Channel Access in Unlicensed Spectrum," filed on 11 December 2011, the contents of both applications are hereby incorporated by reference in their entirety. technical field [0002] The present invention relates to methods and systems for wireless communications and, in particular embodiments, to methods and systems for adaptive Listen-Before-Talk (LBT) channel access in unlicensed spectrum. Background technique [0003] It is predicted that mobile data usage will increase 11-fold by 2018. To meet this challenge, many new technologies have been proposed to improve the data rate in the fifth-generation 5G mobile wireless network communication systems. Howeve...
