Communication device for communicating within a group of communication devices. The communication device comprising circuitry configured to listen to a training and control period of a further communication device which is acting as a wireless network coordinator of a further group of communication devices and transmits frames with a succession of directive beams, each identified by a transmit sector and to generate reception quality information associating each transmit sector with a quality indicator indicative of a reception quality of the received frames. Further, the circuitry is configured to obtain scheduling information from the further communication device including at least one scheduled data transfer period with transmit sector information associated therewith, and to generate scheduled data transfer periods for the group of communication devices based on the reception quality information and the scheduling information, including the transmit sector information, such that interference levels at the further communication device and/or another communication device are minimized.
