METHODS AND APPARATUS FOR MAPPING MODULATION SYMBOLS TO RESOURCES IN OFDM SYSTEMS

摘要

A transmission resource in a time domain subframe is divided into a plurality of equal duration resource elements in a time and frequency domain, the plurality of resource elements are segregated into a plurality of resource regions, information to be transmitted is modulated to generate a sequence of modulation symbols at a transmitter, the sequence of modulation symbols is mapped into the plurality of resource elements in the plurality of resource regions, and the modulation symbols are transmitted via a plurality of antennas using the respective corresponding resource elements to a receiver. The mapping of the modulation symbols in at least one resource region is independent of a certain control channel information that is carried in the time domain subframe, and the mapping of the modulation symbols in at least another resource region is dependent upon that certain control channel information.

1. A method for transmitting bits in a wireless communication system, the method comprising:
determining a number of bits for each of a plurality of code blocks, wherein a number of bits for at least one code block at an end of the plurality of code blocks is determined based on a ceiling function of N1/Nseg, wherein a number of bits for at least one code block at a beginning of the plurality of code blocks is determined based on a floor function of N1/Nseg, and where N1 is associated with a number of symbols available for data transmission and Nseg is associated with a number of code blocks; transmitting bits based on the number of the bits for each of a plurality of code blocks to a receiver via one or more antennas.
