METHOD OF TRANSMITTING DOWNLINK CHANNEL RANK INFORMATION BY USING PHYSICAL UPLINK SHARED CHANNEL

摘要

PURPOSE: A transmission method of downlink channel rank information is provided to execute encoding by applying liner combination to channel rank information bit more than 3 bits. CONSTITUTION: Channel rank information to be transmitted is mapped to a channel rank information bit string more than 3 bit(S310). The channel rank information bit string us reed-muller-coded using a basis sequence of 32 bit code length(S320). A reed-muller coding is able to be expressed by the basis sequence. The channel rank information is reed-muller-coded using the basis sequence of 32 bit code length. Modulation symbols are created by applying a bit sequence which is reed-muller-coded to a modulation mapper(S330).
