Abstract
An apparatus and method for adaptive broadcast transmission. A broadcast transmission can be received. Insufficiency of a broadcast channel quality can be determined. A negative acknowledgement signal can be sent on a common uplink channel in response to determining the broadcast channel quality is insufficient. The negative acknowledgement signal can be received on the common uplink channel at another location, the negative acknowledgement signal indicating broadcast channel quality is insufficient. The broadcast channel quality can be adjusted in response to receiving the negative acknowledgement signal.
