Systems and methods for multiplexing control information onto a physical data channel

A method implemented in a mobile station for a wireless communication system, the method comprising:

• providing first data to be transmitted on a first data channel, second data to be transmitted on a second data channel, control data for the first data channel and control data for the second data channel;
• multiplexing the first data with the control data for the second data channel;
• and
• transmitting the multiplexed data on the first data channel, transmitting the second data on the second data channel, and transmitting the control data for the first data channel on a control channel.

A method implemented in a base station for a wireless communication system, the method comprising:

• receiving data on a first data channel, a second data channel, and a control channel;
• decoding control data received via the control channel;
• using the control data received via the control channel to decode multiplexed data received via the first data channel;
• demultiplexing the multiplexed data received via the first data channel to obtain additional control data;
• and
• using the additional control data received via the first data channel to decode data received via the second data channel.

A wireless communication system comprising:

• a mobile station configured to
• provide first data to be transmitted on a first data channel, second data to be transmitted on a second data channel, control information for the first data channel and control information for the second data channel,
• encode and multiplex the first data with the control information for the second data channel, and
• transmit the multiplexed data on the first data channel, transmit the second data on the second data channel, and transmit the control information for the first data channel on a control channel;
• and
• a base station configured to
• receive the multiplexed data on the first data channel, the second data on the second data channel, and the control information for the first data channel on the control channel
• decode the control information for the first data channel,
• decode the multiplexed data using the control information for the first data channel,
• demultiplex the multiplexed data into the first data and the control information for the second data channel, and
• decode the second data using the control information for the second data channel.

A mobile station for a wireless communication system comprising:

• a transceiver subsystem;
• and
• a processing subsystem coupled to the transceiver subsystem and configured to
• provide first data to be transmitted on a first data channel, second data to be transmitted on a second data channel, control data for the first data channel and control data for the second data channel, and
• multiplex the first data with the control data for the second data channel;
• and
• wherein the transceiver subsystem is configured to transmit the multiplexed data on the first data channel, transmit the second data on the second data channel, and transmit the control data for the first data channel on a control channel.
