Abstract

Certain aspects of the present disclosure are directed to an apparatus for wireless communication. The apparatus generally including a processing system configured to generate a first frame includingan indication of whether resources are available to be shared with a first one or more wireless nodes, where the apparatus is part of a first basic service set and the first one or more wireless nodesare part of one or more second basic service sets, and a first interface configured to output the first frame for transmission.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Application Serial No. 16 / 028,332, filed July 5, 2018, which claims priority to U.S. Provisional Patent Application Serial No. 62 / 530,055, filed July 7, 2017 rights and interests, the entire contents of the above two applications are incorporated herein by reference. technical field [0003] In general, certain aspects of the present disclosure relate to wireless communications, and more specifically, certain aspects of the present disclosure relate to coordinated uplink transmissions. Background technique [0004] The 60 GHz band is a license-exempt band characterized by a large amount of bandwidth and a large worldwide overlap. High bandwidth means that very high volumes of information can be sent wirelessly. As a result, a variety of applications, each requiring transmission of large amounts of data, can be developed to allow wireless communication around the 60 GHz band. ...
