Abstract
The institute of electrical and electronics engineers
(IEEE) 802.16e is designed to support a wide range of applications with
various quality of service requirements. Since MAP signaling overhead
can unacceptably be large for voice traffic, IEEE 802.16e suggests the use
of multicast sub-MAPs whose messages are encoded according to the channel
condition. In this case, it is desirable for the base station to properly
choose a modulation and coding set associated with the channel condition.
In this letter, we consider the use of an adaptive modulation coding scheme
for the multicast sub-MAPs without explicit information on the channel
condition. The proposed scheme can achieve the same MAP coverage as
the broadcast MAP while minimizing the signaling overhead. Simulation
results show that when it is applied to voice-over-internet protocol (VoIP)
services, the proposed scheme can significantly enhance the VoIP capacity.
