CARRIER SENSING MULTIPLE ACCESS APPLIED ON SUBCARRIERS WITH NOT FULL-DUPLEX CAPABLE ACCESS POINTS

摘要

A first communication device and a method performed thereby are provided for communicating with at least a second communication device. The first and the second communication device are operable in a wireless communication network employing contention based access for radio resources comprising a plurality of frequency subcarriers, wherein at least the second communication device transmits a control sequence on at least one subcarrier of a predefined subcarrier pattern when transmitting data. The method comprises: demodulating the radio resources on at least a subset of subcarriers of the predefined subcarrier pattern; and determining whether the demodulated radio resources comprise the control sequence; that being the case: refraining from transmitting data to the second communication device; and otherwise: transmitting data to the second communication device.
