摘要： A method is disclosed for use in wireless communication systems employing dynamic resource allocation schemes (Dynamic Channel Allocation, DCA) together with Link Adaptation (LA) schemes. The method allows to provide individually optimized Quality of Service to each of a plurality of services. This is achieved by exclusively mapping data belonging to one single service to a Physical Data Block. Based on information about the packets, the services and/or the shared physical channels, scheduling metrics are calculated, based upon the scheduling metrics it is decided which of said services is to be served next. Therefore, it is possible to adapt the transmission parameters of physical channels individually to the required Quality of Service of data transmitted over the channel. As a further advantage, the transmission capacity of the physical channel can be economically utilized.

摘要： A method is disclosed for digital data transmission using higher order modulation schemes, wherein a plurality of bits is mapped to bit positions of a symbol and the transmission has different error probabilities for at least two out of said bit positions. A data bit is mapped to a bit position in a first modulation scheme and transmitted in a symbol on the mapped bit position of the first modulation scheme. When a request is received from a receiver, for retransmission of a data block containing this data bit, a decision is made about a re-transmission of said bit, based on a reliability of the bit position in the first transmission, and if it is decided to retransmit the bit, the data bit is mapped to a bit position of a second modulation scheme and retransmitted in a symbol on the mapped bit position of the second modulation scheme.

摘要： A method is provided which improves reliability of channel estimation in a digital communication system by reducing the ambiguity in the recognition of received symbols evaluated for the channel estimation. A data word transmitted according to a first mapping of data word values to modulation states is re-transmitted at least once with a second, re-arranged mapping of data word values to modulation states. The second mapping and possible further mappings are generated from the first mapping in a way that the number of different results which can be obtained from combining the transmitted original data symbol and the re-transmitted counterpart data symbol(s) is lower than the number of original modulation states in the first mapping.

摘要： The present invention relates to a method for balancing the distribution of interference between radio cells in a wireless communication system comprising cells in which subcarrier blocks are used for communication. A number of adjacent cells build a cell cluster. Moreover, the present invention relates to a corresponding method adapted for use in a system in which multi beam antennas or multiple antennas are used. Furthermore, the present invention relates to base stations performing the above method as well as a communication system comprising the base stations. To reduce the large average SIR variations without causing additional SIR estimation, measurement and calculation problem as introduced with power control the invention suggests to group subcarrier blocks into a plurality of subcarrier block sets in each cell of a cell cluster, to determine transmission power levels for each of the cells of said cell cluster, and to assign transmission power levels to the subcarrier block sets.

摘要： The present invention relates a method and a decoder for decoding codewords, the decoding being performed as message passing on a graph representation of the code, e.g. on low density parity-check (LDPC) code, wherein for each non-zero entry in a parity check matrix, the message matrix elements of a first message matrix are initialized with data obtained from a demodulator, and the elements of a second message matrix are determined based on message matrix elements of said first message matrix. Further, a decoded codeword is reconstructed based on the data obtained from the demodulator and the matrix elements of the second matrix. Moreover the present invention relates to and to a communication system, a mobile terminal and a base station comprising the decoder. To reduce the influence of wrong information the decoding method uses subset of matrix elements from said first/second matrix for determining a matrix element of said second/first matrix, wherein the matrix elements of said subset fulfill a reliability criterion.

摘要： A hybrid ARQ retransmission method in a communication system, wherein data packets being encoded with a forward error correction (FEC) technique prior to transmission, are retransmitted based on an automatic repeat request and subsequently soft-combined with previously received erroneous data packets either on a symbol-by-symbol or a bit-by-bit basis. The symbols of said erroneous data packets are modulated by employing a predetermined first signal constellation. The symbols of the retransmitted data packets are modulated by employing at least a predetermined second signal constellation. Each symbol bit has a mean bit reliability defined by the individual bit reliabilities over all symbols of the predetermined signal constellation. According to the invention, the predetermined first and the at least second signal constellation are selected such that the combined mean bit reliabilities for the respective bits of all transmissions are averaged out.
