Abstract

A set of nodes may communicate in a manner that is asynchronous with respect to the communication between other sets of nodes. To facilitate reservations of resources by different nodes / a node (D) may transmit a message (Rx-RUM-D) that requests neighboring nodes to limit their interfering transmissions on a given resource and then transmit another message (RRM-D) to inform the neighboring nodes that the node is no longer using the resource. To address problems that may be caused by concurrent asynchronous transmissions by different nodes, a messaging scheme may be used to enable a first node to acquire control information transmitted by asynchronous neighboring nodes while the first node was transmitting, and was thereby unable to receive control messages.

Description

technical field [0001] The present application relates generally to wireless communications, and more particularly, but not exclusively, to messaging for managing interference. Background technique [0002] The deployment of wireless communication systems typically involves implementing some form of interference mitigation scheme. In some wireless communication systems, interference may be caused by neighboring wireless nodes. As an example, in a cellular system, wireless transmissions from a handset or base station in a first cell may interfere with communications between handsets and base stations in neighboring cells. Similarly, in a Wi-Fi network, wireless transmissions by access terminals or access points of a first serving set may interfere with communications between access terminals and base stations of adjacent serving sets. [0003] U.S. Patent Application Publication No. 2007 / 0105574, the disclosure of which is hereby incorporated herein by reference, describes ...
