Methods and apparatus are presented for acknowledging missed control channel
messages. In a system wherein control channel messages can be used to send the
transmission parameters of signals on a data traffic channel, the inability to
decode the latest control channel message can cause a delay in system throughput.
Functionality is added to the acknowledgment channel, which is already in place
to acknowledge the receipt of data subpackets on the data traffic channel, so that
acknowledgments of missed control channel messages can be conveyed. A pattern or
multiplicity of acknowledgment signals can be used to request transmissions of
control channel messages. An infrastructure element can be configured to read the
acknowledgment signals as a request for a broadcast on the control channel.
