Internet-Draft Location Measurements for 802.16e June 2009
Abstract
IEEE 802.16e defines means for true mobility within an 802.16
wireless network. Determining an accurate location for 802.16e
devices requires information on radio parameters. A format is
defined for location-related measurement data that can be provided by
an 802.16e device. This measurement data can be used by a Location
Information Server (LIS) to more accurately determine the location of
the device. A separate measurement used for identifying WiMAX
session-related parameters is also provided.

Internet-Draft Location Measurements for 802.16e June 2009
1. Introduction
Determining the location of a device in an IEEE 802.16e [IEEE.80216E]
mobile wireless network requires information from the device to
improve the accuracy of the final result. Radio timing information
provided by the device can enable the calculation of a more accurate
location estimate by a Location Information Server (LIS).
This document describes a standard format for 802.16e measurement
data that is based on radio measurements made of base stations near
the device.

2. Conventions used in this document
This document builds on [I-D.thomson-geopriv-held-measurements] and
consequently uses the same set of terminology. Terminology from
[IEEE.80216E] is used where appropriate.
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119].

3. 802.16e Radio Measurement Data
A subscriber station (SS) in an 802.16e network is able to observe
radio signals from each base station (BS) in its proximity. By
observing the timing and strength of these signals, a SS is able to
provide a LIS with information that can be used to determine its
location.
The most basic 802.16e measurement indicates the serving BS, as shown
in Figure 1.
See RFCXXXX.
