    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： Methods and apparatus for transmitting power setting information in a downlink Physical Downlink Shared Channel (PDSCH) in a communication system. In this communication system, a plurality of methods for calculating traffic-to-pilot ratios (T2P) are established. In addition, a mapping scheme between a plurality of overhead signals and a plurality of reference signal (RS) overhead ratios, ηRS, and the plurality of T2P calculation methods is established. A user-specific T2P ratio PB,k/PRS for certain OFDM symbols, a RS overhead ratio ηRS and a calculation method selected from the plurality of T2P calculation methods are assigned to a wireless terminal. Then, an overhead signal corresponding to both of the assigned RS overhead ratio ηRS and the assigned T2P calculation method is selected in accordance with the mapping scheme and is transmitted to the wireless terminal. In addition, the user-specific traffic-to-pilot ratio PB,k/PRS is transmitted to the wireless terminal. The wireless terminal may calculate the traffic-to-pilot ratios across different transmission antennas and different OFDM symbols in dependence upon the received traffic-to-pilot ratio PB,k/PRS, and the RS overhead ratio and the T2P calculation method indicated by the RS overhead signal.

    摘要： Methods and apparatus for generating cyclic redundancy checks (CRCs). In one aspect of the present invention, a plurality of cyclic redundancy checks are calculated based upon a plurality of bits by using a selected cyclic redundancy check generator polynomial, at least one cyclic redundancy check is calculated based upon a first subset of the plurality of bits with a certain bit ordering, and at least another cyclic redundancy check is calculated based upon a second subset of the plurality of bits with a different bit ordering. The second subset of bits may overlap with the first subset of bits. In another aspect, a plurality of cyclic redundancy checks are calculated based upon a plurality of bits by using a plurality of different cyclic redundancy check generator polynomials. A first cyclic redundancy check generator polynomial is used for calculating a first cyclic redundancy check based upon a first plurality of bits, and a second cyclic redundancy check generator polynomial is used for calculating a second cyclic redundancy check based upon a second plurality of bits.
