    摘要: An ARQ (re-) transmission method of transmitting data in a wireless communication system wherein data packets are transmitted from a transmitter to a receiver, using a first transmission and a second transmission based on a repeat request. The method comprises the steps of modulating data at the transmitter using a first signal constellation pattern to obtain a first data symbol. The first data symbol is transmitted as the first transmission to the receiver using a first diversity branch. Further, the data is modulated at the transmitter using a second signal constellation pattern to obtain a second data symbol. Then, the second data symbol is transmitted as the second transmission to the receive over a second diversity branch. Finally, the received first and second data symbol data symbol are diversity combined at the receiver. The invention further relates to a transmitter and a receiver embodied to carry out the method of the invention.

    摘要: The invention relates to feedback transmission for data packets in a mobile communication system. In particular the invention provides a communication system wherein feedback information of a retransmission protocol for transmitted data packets is transmitted. Further, the invention relates to a method for determining radio resources for the transmission of feedback information of a retransmission protocol for transmitted data packets as well as to a base station and a mobile station performing the method.

Another aspect of the invention is the generation of a new AICO (Antipodal Inverted COnstellation) mapping scheme.

    摘要: Transmit diversity system in which constellation rearrangement is used. Both diversity signals contain the same data and both are 16-QAM, but the location of the data bits within the constellation is different. This averages the effect of the different levels of reliability of the different constellation points. A method for modifying a quadruple of data bits in a data transmission system using Quadrature. Amplitude Modulation with 16 different modulation states, 16-QAM, using an Antipodal Inverted Constellation AICO) mapping, swapping bits selecting contiguous symbol regions with bits selecting non-contiguous symbol regions. Depending on the particular pre-defined mapping and on the particular permutation of bits, inversion of selected bits may be performed in addition. The quadruples thus obtained are mapped to modulation symbols according to a pre-defined AICO mapping. In the corresponding method for receiving the symbols, likelihood values are swapped and modified in a way which is complementary to the permutation and inversion of bits, before they are combined with likelihood values from other symbols representing the same bits. Method ensures that there is a one to one correspondence between Hamming distance and Euclidian distance for the combined received data. In other words it ensures that, once combined, all 4 bit data words which differ by the same number of bits (Hamming distance) are the same distance apart in the constellation (Euclidian distance).

    摘要: The invention relates to a message for reporting a channel quality of a communication system, a corresponding method and apparatuses performing such method. The invention is inter alia applicable to a 3GPP LTE and LTE-A system as standardized by the 3rd Generation Partnership Project (3GPP). The invention provides a structure (message) that allows conveying channel quality information in a manner allowing an unambiguous identification of the size channel quality information. This is achieved by defining a message comprising a first channel quality field consisting of a known number of bits, and a second channel quality field consisting of a variable number of bits. The number of bits and structure (of the content of the bits) of the second channel quality field is indicated by the content of the bits of the first channel quality field.
