Abstract

• In this contribution, we propose a framework for the HR-MSs communicate to each in case there is no infrastructure station such as HR-BS or HR-RS presented in the network.

Usage Scenario

Page 5: A Framework for HR-MS to HR-MS Direct Communication without Infrastructure Stations Document Number: IEEE S802.16n-10/0008 Date Submitted: 2011-03-12.

Communication Modes

• Two communication modes– Infrastructure mode– Ad Hoc Mode

Ad Hoc Mode

Initialization DiscoveryCommunic-

ation

• Three system states– Initialization state: set node to ad hoc mode– Discovery state: find other HR-MSs or HR-MS networks in vicinity

and broadcast information of current node. – Communication state: the HR-MS associates to an HR-MS networks.

It now can communicate to other nodes within the network

Functionalities of Coordinators

• Coordinator– Transmit frame preambles regularly. – Accept network association and de-assoication. – Manage the radio resource.– Schedule the data transmission.

Summary

• In this contribution, we propose a framework for 802.16n HR-MSs in setting up HR-MS direct communication network by themselves without turning any node into base station or relay station.

Proposed Text

• 17.1 Overview

An HR-MS should be able to work in two communication modes, infrastructure mode or ad hoc mode. In infrastructure mode, it can only transmit when it synchronization to an infrastructure stations such as HR-BS or HR-RS. In ad hoc mode, an HR-MS is allowed to transmit information before it synchronizes to any other HR stations.

Proposed Text

17.2.2.1 A Framework for the Direct communication between HR-MSs in ad hoc mode

In ad hoc mode, an HR-MS can be in three states as following Figure shows. • Initialization state: initialize the system for ad hoc mode.• Discovery state: only transmit node configuration information from time to time. • Communication state: setup communication links with other HR-MS and transmit

data to each other.

Proposed Text

During the initialization for HR-MS direct communication without infrastructure, HR-MS should set its working mode as ad hoc mode.

After initialization, HR-MS should listen to channel first. It should check whether there are other HR-MSs or HR-MSs networks formed by HR-MSs in the same area. The HR-MS should transmit some node information to let other HR-MSs know its existence.

For the HR-MSs to communicate each other, a HR-MS network should be setup first. One of HR-MS should play the role of coordinator. The functionality of coordinator is to transmit frame preambles and DL/UL MAP regularly, manage the node association and leaving, mange the radio resource etc.
