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: Example implementations relate to devices, methods, and computer program products of communication networks in relation to, e.g., involved in initial access from an idle status, connection reestablishment, handover, or synchronization. A terminal apparatus may include: a control module configured to detect receipt of a group information indicative of a group of at least two network apparatuses, the group information being descriptive for a certain configuration of communication parameters enabling the terminal apparatus to communicate with anyone of the network apparatuses of the respective group, and request connecting to at least one of the network apparatuses of the group by use of the certain configuration.
