Abstract

Systems and methods for communicating control data for multiple physical data channels by transmitting control information for a first physical data channel on a physical control channel and combining the control information with information for a logical data channel and transmitting the combined information on a single physical data channel. In one embodiment, a method includes encoding and multiplexing data for a first data channel with control information for a second data channel, transmitting the multiplexed data on the first data channel, transmitting second data on the second data channel, and transmitting the control information for the first data channel on a control channel. The multiplexed data is then decoded using the control information from the control channel and demultiplexed. The demultiplexed control information for the second data channel is then used to decode the data on the second data channel.
