摘要： A method of transmitting data packets over an air interface is disclosed. At least a first and second stream of data packets are multiplexed, wherein a multiplexed stream of data packets is generated. The multiplexed stream of data packets is processed by a forward error correction function, wherein the forward error correction function adds redundancy bits to the multiplexed stream of data packets, wherein a third stream of data packets is generated, and wherein the redundancy bits are used for an error control to be performed on the third stream of data packets. The third stream of data packets is then transmitted over the air interface.
