    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 edge) 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 neighboring 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)可以将生成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(例如,小区边缘)的小区中 )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。
