Abstract
A method and system for transport block size signaling where information including a first modulation scheme, first transport block size, and first redundancy version may be transmitted. The first transport block size and first redundancy version each are represented by a set number of bits. A packet is transmitted using the first modulation scheme. Second information is transmitted including a second modulation scheme, second transport block size, and second redundancy version. The second transport block size is represented by a set number of bits larger than the number of bits representing the first transport block size. The second redundancy version is represented by a set number of bits less than the number of bits representing the first redundancy version. The packet is re-transmitted using the second modulation scheme. The system may use Wideband Code Division Multiple Access (WCDMA) that implements High Speed Downlink Packet Access (HSDPA).
