Problems solved by technology

Conventional methods of reducing this interference, such as contention-based media access rules, may have undesired effects on data transfer rates
Such a solution may also require the deployment of a central access point, and thus may not be suitable for systems where communication occurs directly between peers

Embodiment Construction

[0014] figure 1 A wireless communication system 100 is depicted that includes multiple sets of wireless services. in particular, figure 1 A first set of services including wireless computing devices 104 and 108 and a second set of services including wireless computing devices 112 and 116 are illustrated. The nature and population of each service set are not particularly limited. As will be apparent to those skilled in the art, each service set may be a personal basic service set (PBSS) composed of at least one pair of computing devices in communication with each other. In other examples, each service set may be a basic service set (BSS) that includes an access point (not shown).

[0015] exist figure 1 In the example shown in , computing device 104 is a media server and computing device 108 is a television that wirelessly receives media from device 104 for playback. Furthermore, computing device 112 is a personal computer, and device 116 is a mobile computing device, such...

Abstract

A method for spatial re-use in a first wireless communications assembly of a first service set, comprising: establishing data transfer communications within the first service set; detecting wireless interference generated by a second wireless communications assembly of a second service set distinct from the first service set; responsive to the detecting, sending a notice of interference indicator to the second wireless communications assembly; receiving a response to the notice of interference indicator from the second wireless communications assembly; based on the response, selecting an interference-reducing corrective action to perform within the first service set; and initiating the selected corrective action within the first service set.

Description

[0001] Cross References to Related Applications [0002] This application claims U.S. Provisional Patent Application No. 62 / 352204, filed June 20, 2016, No. 62 / 417503, filed November 4, 2016, and No. 62, filed January 12, 2017 / 445341 priority. The contents of each of the above applications are hereby incorporated by reference. technical field [0003] The present specification relates generally to wireless communications, and in particular to methods and apparatus for de-centralized spatial reuse in wireless communications systems. Background technique [0004] With the proliferation of wireless communications, an increased incidence of interference with each other by different collections of wireless devices employing the same wireless channel within a sufficiently small physical space can be expected. Conventional methods of reducing this interference, such as contention-based media access rules, may have undesired effects on data transfer rates. Such a solution may al...
