Abstract: Methods and apparatuses for Orthogonal Frequency Division Multiplexing (OFDM) based communication are disclosed. In a method at least some least important bits derived from data to be transmitted are mapped into at least one portion of an OFDM transmission unit, the at least one portion being reserved for the least important bits. More important bits derived from said data are mapped into a different portion of the ODFM transmission unit.

Abstract: A technique including: controlling a radio device of a first cell to transmit information identifying one or more radio resources allocated to both downlink and uplink transmissions of a type of reference signal in the first cell; and controlling the radio device to transmit the type of reference signal in the first cell using the one or more radio resources; wherein the one or more radio resources are excluded from use for transmission of the type of reference signal in one or more other interfering cells.

Abstract: A signal modulated according to zero-tail discrete Fourier transform spread orthogonal frequency division multiplexing (ZT DFT-s-OFDM) is received over a channel. The signal is down-sampled into a first sequence including N samples, N corresponding to the number of used subcarriers. The first Nh samples and the last Nt samples are removed from the first sequence, thereby obtaining a second sequence having a length of N-Nh-Nt. The second sequence is correlated with a reference sequence which has a length N-Nh-Nt, and a frequency response of the channel is estimated over the N used subcarriers based on a result of the correlation.

Abstract: A method is disclosed for signal processing in a radio system. The method comprises generating (801), in an apparatus (602), a single carrier frequency division multiplexing SC-FDM signal having a shorter duration than a time symbol duration defined by a radio standard applied in the radio system. The signal is transmitted (802) from the communications apparatus (602). The method comprises receiving (803) said signal from the communications apparatus (602), wherein orthogonality of frequency subcarriers is maintained at a receiver (601) of the signal.

Abstract: An apparatus (UEA) may generate a zero-tail signal to be transmitted in an LTE/LTE-A cell, by introducing time domain samples with zero power or very low power in specific positions of a time symbol tail. The apparatus (UEA) may transmit the generated zero-tail signal to a base station (eNB), such that a first user terminal (UEA) is located in the cell farther away (e.g. on a cell egde) from the base station (eNB) than a second user terminal (UEB). Thus coexistence of signals sent by user terminals (UEA, UEB) located at different distances from the base station (eNB) within a same receiver window is enabled without inter-symbol interference. The generated zero-tail signal may also be transmitted from the first user terminal (UEA) or from the base station (eNB) in an outdoor system that is detectable by a neighbouring indoor system.
Abstract translation: 通过在时间符号尾部的特定位置引入具有零功率或非常低功率的时域采样，装置（UEA）可以生成将在LTE / LTE-A小区中发送的零尾信号。 该装置（UEA）可以将产生的零尾信号发送到基站（eNB），使得第一用户终端（UEA）位于距离基站（eNB）更远的小区（例如，小区egde）处 ）比第二用户终端（UEB）。 因此，能够在没有符号间干扰的情况下启用位于与基站（eNB）不同距离处的同一接收机窗口内的用户终端（UEA，UEB）发送的信号的共存。 所产生的零尾信号也可以从邻近室内系统可检测的户外系统中的第一用户终端（UEA）或基站（eNB）发送。
