    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: To improve the reliability of channel estimation, data symbols at determined positions of the transmitted data stream are replaced by quasi-pilot symbols. The quasi-pilot symbols carry data modulated onto the carrier with a different modulation scheme than the original symbols. The modulation scheme for the quasi-pilot symbols has a lower amplitude and/or phase ambiguity than the modulation scheme for the original data symbol.

    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: An ARQ transmission method in a communication system, wherein data packets comprising modulation symbols are transmitted based on an automatic repeat request and subsequently combined with previously received data packets. The symbols of the transmitted data packets are modulated in a mapping entity employing at least a first and second signal constellation. The method further comprises the step of obtaining the second signal constellation from the first signal constellation by exchanging a logical bit position and/or inverting a logical bit. The invention further relates to a corresponding transmitter and receiver.

    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.

    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.
