Introduction
• Motivation
– The IEEE 802.16 standard adopts Adaptive Antenna System (AAS) as
an option to enhance cell capacity and coverage.
– The feature of AAS is its ability to reduce interference by steering the
beam to a specific user.
– To increase system capacity and support users with poor channel
condition to guarantee QoS
– In section 6.3 of 802.16m SRD,
“IEEE 802.16m shall support QoS classes, enabling an optimal
matching of services, application and …..”
• Purpose
– Propose to enable radio resource management for AAS in IEEE
802.16m system
• An simple example is given in the following

Radio Resource Management for AAS
Substrate lifetime of
each user by nonAAS-zone duration
Beginning of

Lifetime > 0
First stage
scheduling
Classified users into
the four queues
according to
modulation scheme.
Define the priority of
users in each queue by
Early Deadline First
scheduling policy
Second stage
scheduling
Construct
beamforming
according to priority
set in first stage
Estimated users SINR
after beamforming, and
check the burst profile
Burst profile is
BPSK
Served in non-AAS

– [In the IEEE 802.16e-2005 standard, AAS works as an
optional mode. The frame structure, private messages, and
network entry procedure for AAS transmission can be
modified in new system. The messages associated with AAS
controls includes AAS preamble, AAS compressed MAP,
AAS Downlink Frame Prefix (AAS-DLFP), AAS Alert Slot,
and some AAS exchanging messages
(AAS_FBCK_REQ/RSP, AAS_BEAM_SELECT,
AAS_SDMA_DL_IE, etc).]
