摘要： A method of transmitting a control channel format indicator (CCFI), also known as PCFICH (Physical Control Format Indicator Channel), in case where the length of a coded CCFI is not an integer multiple of three, including mapping a plurality of two-bit CCFI into a codebook with each component codeword having three bits; generating a sequence of codewords selected from the codebook by repeating the selected component codeword for predetermined times; generating a codeword by concatenating the sequence of the selected component codewords with the original CCFI bits; and transmitting the codeword carrying information of CCFI. The method further includes a step of generating a permutation of each of the four codewords by assigning K repetitions of the three-bit component codeword to the number of K resource units respectively and mapping remaining K bits of each of the four codewords separately to the number of K resource units.

摘要： A method for transmission, by dividing a transmission resource in a time domain subframe into a plurality of equal duration resource elements in a time and frequency domain, segregating the plurality of resource elements into a plurality of resource regions, modulating information to be transmitted to generate a sequence of modulation symbols at a transmitter, mapping the sequence of modulation symbols into the plurality of resource elements in the plurality of resource regions, and transmitting the modulation symbols 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 said time domain subframe, and the mapping of the modulation symbols in at least another resource region is dependent upon said certain control channel information that is carried in said subframe. The information to be transmitted may be encoded to generate a plurality of code blocks, with roughly equal number of resource elements assigned to each of the plurality of code blocks in at least one resource region. Alternatively, the time domain subframe may contain only one resource region.

摘要： The present invention relates to a method for data transmission in a communication system. The method includes determining, at the transmitter, whether to transmit data signal using a single codeword or two codewords. When it is determined that the single codeword transmission is used, coding, by the transmitter, a control signal by using a first signal format, with the control signal coded by the first signal format carrying information regarding the single codeword. When it is determined that the two codewords transmission is used, coding, by the transmitter, the control signal by using a second signal format, with the control signal coded by the second signal format carrying information regarding both of the two codewords. The method also includes transmitting the data signal and the control signal according to the determined transmission format from the transmitter to the receiver.

摘要： A method from transmitting data via multiple antennas. In this method, four information bits to be transmitted are multiplexed by using either one of a code division multiplexing scheme or a second code division multiplexing scheme combined with a real and imaginary multiplexing scheme, to generate a code division multiplexed symbol including four vectors. Then, the code division multiplexed symbol is repeatedly transmitted by alternatively applying two transmit diversity schemes via four transmission antennas.
