摘要： A first unit for use in a base station in a mobile telecommunication network is adapted to use an identity for identifying a mobile terminal or for identifying a channel in the uplink. The first unit manages information of at least one additional identity of a mobile terminal or a channel belonging to at least a second base station for interference mitigation purposes. The first unit detects whether the mobile terminal or channel identified by the additional identity is active and mitigates cell-interference caused by an active mobile terminal or a channel identified by the additional identity. A second unit reserves at least one identity for identifying a mobile terminal or for identifying a channel in order to make the at least one identity identifiable to at least a second base station.

摘要： Systems and methods of performing data transmission and reception in a communication system are presented. In one exemplary embodiment, a method performed by a wireless device for transmitting a signal in a first communication system that is frequency-domain multiplexed with a second communication system may include generating (201), by a modulator (401), a modulated signal that represents one or more information symbols. The modulated signal may include one or more modulation symbols of the first communication system. The method may also include filtering (203), by a pulse shaping filter (403), the modulated signal to obtain the filtered modulated signal. The pulse shaping filter (403) may be configured to operate with a period that corresponds to the symbol rate of the second communication system. In addition, the method may include transmitting (209), by a transmitter (409), the filtered modulated signal at a carrier or sub-carrier frequency of the first communication system.

摘要： A mixed numerology OFDM system is presented herein relative to a first OFDM numerology having a first subcarrier spacing and associated with a first signal having a first length. A second signal having a second length and associated with a second OFDM numerology having a second subcarrier spacing greater than the first subcarrier spacing is generated by generating a sub-frame comprising redundant data appended to each of a plurality of OFDM symbols and generating the second signal by appending group redundant data to the sub-frame such that the second length equals the first length. The number of OFDM symbols in the sub-frame is selected such that a length of the sub-frame is as large as possible without exceeding the length of the first OFDM symbol in the first signal. The receiver may extract the first the first and second signals from a received composite signal using a single FFT.

摘要： A method in a network node comprises generating a parity-check matrix for decoding a transmission scheme. The transmission scheme comprises a repetition code, an interleaver, and a modulation having a memory property. The parity-check matrix comprises a function of: a differentiator matrix, the differentiator matrix comprising an inverse of an accumulator matrix; a deinterleaver matrix, the deinterleaver matrix comprising an inverse of an interleaver matrix, the interleaver matrix comprising a square unitary permutation matrix for introducing randomness; and a repetition decoder matrix.

摘要： A method of a wireless communication device for operation in a wireless communication network comprising a plurality of cells is disclosed. The method comprises performing radio resource management measurements based on received reference signals of one or more of the cells, wherein the radio resource management measurements are performed over a bandwidth comprising K subcarriers. The method also comprises organizing the K subcarriers into N blocks, wherein each block comprises adjacent subcarriers, performing coherent averaging of the radio resource management measurements over the adjacent subcarriers of each block to produce intermediate measurement results and performing non-coherent averaging of the intermediate measurement results to produce a radio resource management measurement result. The method further comprises detecting whether a condition is fulfilled, wherein the condition is suitable for determining if the wireless communication device is in a dense network scenario, setting N to a first value if the condition is fulfilled and to a second value if the condition is not fulfilled, wherein the first value is lower than the second value. Corresponding arrangement, wireless communication device and computer program product are also disclosed.
