    摘要： The invention relates to a method for deactivating a semi-persistent resource allocation of a user equipment in an LTE-based mobile communication system. Furthermore, the invention also related to a user equipment and a eNode B implementing this method. To provide a mechanism for deactivating a semi-persistent resource allocation in a LTE system which is not requiring any changes to the Physical layer-to-MAC layer interface and/or preferably no changes to the PDCCH formats agreed by the 3GPP a combination of NDI value and MCS index is defined that is commanding the release of SPS resources. Alternatively, another solution proposed to define a special transport block size that when signaled in a PDCCH is commanding the release of SPS resources.

    摘要： The invention relates to methods and apparatuses for providing HARQ feedback in a mobile communication system using carrier aggregation. To suggest a scheme for transmitting feedback on the successful/unsuccessful decoding of transmissions that is operable in FDD mode, the invention proposes to utilize only a single one of plural radio resources available for feedback transmission for signaling feedback for multiple transmissions. A feedback sequence of ACK/NACKs for the transmissions is mapped to one feedback resource combination that is one of the radio resources available for feedback transmission and a modulation symbol of the given modulation scheme that is transmitted on said one radio resource. This scheme can also be used in cases where the number of possible feedback sequences of ACK/NACKs for the transmissions is larger than the number of feedback resource combinations available for feedback transmission.

    摘要： The invention relates to a method and scheduling apparatus for reserving radio resources in radio resource block units in a mobile communication system for a plurality of users. Further, another aspect of the invention is the indication of a radio resource reservation in radio resource block units in a mobile communication system to one of a plurality of mobile terminals. To provide a new mechanism allowing an efficient utilization of radio resources the invention proposes a resource reservation mechanism that reserves radio resources for a plurality of users in resource block units. Thereby, individual resource blocks are reserved for the individual users for a reservation period that comprises a plurality of time slots (or sub-frames). Further, the resource block reservations for the users overlap at least partially among the users, i.e. individual ones of the resource blocks are reserved for plural users.

    摘要： This invention relates to the proposal of component carrier (de)activation message that is allowing a activation or deactivation of one or more component carriers in the uplink or downlink. Furthermore, the invention relates to the use of the new component carrier (de)activation message in methods for (de)activation of downlink component carrier(s) configured for a mobile terminal, a base station and a mobile terminal. To enable efficient and robust (de)activation of component carriers, the invention proposes to use component carrier-specific or cell-RNTI(s) for the scrambling of the CRC of the component carrier (de)activation message, and to explicitly indicate the intended recipient of the component carrier (de)activation message in a corresponding field in the message. Furthermore, the invention further proposes different designs of the component carrier (de)activation message and further uses thereof, so as to trigger CQI reporting and/or SRS transmission by a mobile terminal.

    摘要： A method for balancing the distribution of interference between radio cells in a wireless communication system including cells in which subcarrier blocks are used for communication, a number of adjacent cells building a cell cluster. A corresponding method is for use in a system using multi beam antennas or multiple antennas. Base stations perform the above method and a communication system includes the base stations. To reduce the large average SIR variations without causing additional SIR estimation, measurement and calculation problem as introduced with power control, subcarrier blocks are grouped 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 the cell cluster, and to assign transmission power levels to the subcarrier block sets.

    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 first plurality of bits is mapped to a modulation state according to a given Gray mapping of binary numbers to modulation states and transmitted. The plurality of bits is re-transmitted at least once, with a sub-set of bits contained in the plurality of bits inverted, and mapped to further modulation states according to the same Gray mapping. The bits to be inverted are determined in a way that the number of different vector sum results obtainable, for all combinations of bit values within the first plurality of bits, by adding vectors representing complex values of the first and further modulation states in a complex plane, is lower than the number of different modulation states within the Gray mapping.
