Here, the users share a common feedback channel period which is divided into some subperiods.

The common feedback channel was used to obtain CQI information from the users [11].

A concept of the common feedback channel and its structure have also been proposed for IEEE 802.16m systems [12, 13].

The base station will keep transmitting the redundant packets until no signal is detected over the common feedback channel.
