Purpose of IEEE P1900 SC

To develop standards dealing with next generation radio and advanced spectrum management

The IEEE P1900 Standards Group was established in the first quarter 2005 jointly by the

IEEE Communications Society (ComSoc) and the IEEE Electromagnetic Compatibility

(EMC) Society. The objective of this effort is to develop supporting standards dealing

with new technologies and techniques being developed for next generation radio and

advanced spectrum management.

1900.4 WG Scope

� The standard defines the building blocks comprising i) network resource managers, ii) device resource managers and iii) the information to be exchanged between the building blocks,

� for enabling coordinated network-device distributed decision making • which will aid in the optimization of radio resource usage, including

spectrum access control,

� in heterogeneous wireless access networks. � The standard is limited to the architectural and functional definitions at

a first stage. � The corresponding protocols definition related to the information

exchange will be addressed at a later stage.

1900.4 WG Purpose

� The purpose is to improve overall composite capacity and quality of service of wireless systems in a multiple Radio Access Technologies (RATs) environment, • by defining an appropriate system architecture and protocols which

will facilitate the optimization of radio resource usage,• in particular, by exploiting information exchanged between

network and mobile Terminals, • whether or not they support multiple simultaneous links and

dynamic spectrum access.

Proposed System Concept –Context & Key Challenges

� Context/target: � Optimization of radio usage resources of next generation wireless systems, while

building on existing standards (e.g., WiFi, WiMAX, GSM, etc.)� Multimode Devices and Networks with dynamic spectrum access capabilities allowing

the use of spectrum resource dynamically or simultaneously among different Radio Access Technologies (RATs)

� User Terminals have Radio Multi-Homing functionalities enabling simultaneous links to several distinct RATs.

� Challenges: � Efficient usage of system capacity & efficient choice of access strategies (low

parameterization overhead & split of optimization complexity between network & users)� Distributed Decision Making.

� Backwards-compatibility to existing wireless radio standards.� Addition of new building blocks transparent to legacy devices.

� Efficient coexistence of Legacy equipment with Next Generation equipment.� Access control distinguishes between Legacy & Next Generation users.

� Approach: Introduce three new building blocks:� Network Reconfiguration Management

• Define resource selection constraints (policies) for user devices.

� Radio Enabler of Reconfiguration Management• Communicate policies & context information to user devices.

� Terminal Reconfiguration Management• Distributed resource selection subject to policies by user devices.

Envisaged Scenarios

� Scenario 1: Network context changes and users adapt to optimally use available resources, e.g operator adds/removes RATs (BS no more operational, etc.).

� Scenario 2: User context changes and remaining users adapt to optimally use available resources, e.g. users arrive/leave.

� Scenario 3: Changes in the allocation of frequency bands to RATs.� Examples:

• a new carrier is added for 3G.• a frequency band previously used for 3G is allocated to WIMAX.• network switches from WiMAX to IEEE802.11n if a large number of users are suddenly close to the

station

Note: All operations need to be transparent for the user !

IEEE P1900.4 – Usage Scenarios (1/3)Why a Distributed Resource Usage Optimization?

When the number of users/devices increases, centralized decision= Many feedback information to send

= Long computation time

� Transfer a part of the task of making decisions to individual terminals (and/or other network elements), which considerably increases network scalability

Why not completely decentralized?

� minimum control is required so that final operating point is optimal for the global

network, which leads to global optimization of each user

� Example 1: Use of policies for “rough” optimization� If few users are present, let everyone use all resources i.e., policies won’t

impose any constraints on resource selection strategies of users.� If many users are present, limit number of RAT connections per user

� From a network capacity usage point of view, assuming a large number of users “N � �” it is better to have “N” users accessing only one system (in particular CSMA, CDMA) compared to “M*N” users accessing “M” systems in parallel.
