Abstract

An apparatus, for wideband communication with one or more transceivers in a wireless communication system using one or more subbands of a predefined wideband, is configured to perform initial Listen-Before-Talk, LBT, for each subband of the predefined wideband so as to determine from the predefined wideband one or more non-occupied subbands on which the wideband communication is allowed during a certain transmission time, and during the certain transmission time, transmit to and/or receive from the transceiver using the non-occupied subbands. During the certain transmission time and in case the initial LBT indicted that one or more of the subbands are occupied, the apparatus is configured to perform a further LBT for the one or more occupied subbands so as to determine one or more of the initially occupied subbands being no longer occupied, and transmit to and/or receive from the transceiver using, in addition to the initially non-occupied subbands, the one or more no longer occupied subbands.
