Abstract

Embodiments provide a base station of an uncoordinated wireless communication system, wherein the communication system is configured to communicate in a radio band used by a plurality of communication systems, wherein the base station is configured to receive an uplink transmission from an end point of the wireless communication system, wherein the base station is configured to transmit, in response to the reception of the uplink transmission, a downlink transmission to the end point in a downlink transmission window, wherein the downlink transmission window is synchronized in time to the uplink transmission, wherein the base station is configured, in case of an expected collision of the downlink transmission with another transmission, to reposition the downlink transmission in time and/or frequency within the downlink transmission window, in order to avoid a collision of the downlink transmission with the other transmission.
