    摘要: The invention relates to method and apparatus for generating modulation symbols according to a second symbol mapping scheme by a symbol mapping unit being adapted to generate symbols according to a first symbol mapping scheme, wherein the first and second symbol mapping schemes define different mappings of data words of a stream to modulation symbols of a modulation scheme according to the respective symbol mapping scheme. Further, the invention relates to a method and apparatus for generating a mapping of data words to modulation symbols of a square 16 QAM constellation, the modulation symbols being representable by an inphase component and quadrature component. One aspect of the invention is the introduction of a bit sequence transformer unit transforming the data words to be mapped to modulation symbols prior to mapping thereby changing the Hamming distance properties of the mapping. 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: This invention concerns concepts for signaling resource allocation information to a terminal that indicates to the terminal assigned resources for the terminal. The terminal can receives downlink control information (DCI), which comprises a field for indicating the resource allocation information of the terminal. This resource assignment field within the DCI has a predetermined number of bits. The terminal can determines its assigned resource allocation information from the content of the received DCI, even though the bit size of the resource allocation field in the received DCI is insufficient to represent all allowed resource allocations. According to an embodiment, the received bits that are signaled to the terminal in the DCI represent predetermined bits of the resource allocation information. All remaining one or more bits of the resource allocation information that are not included in the field of the received DCI are set to predetermined value.
