5.5.3 Radio Bandwidth Limitation
In multi access systems, performances are related to the number of
ATs connected to the same RN, in terms of throughput. In order to
make the system have nearly the same performances, as the number of
served terminals changes, a limitation of the air capacity is provided.
This functionality performed by the MAC can reduce the user bit rate
on the radio link, by inserting idle cells in slots that could carry traffic
cells. The percentage of not used slots is configurable from CP-EM.
