The data transmission apparatus (100) is configured for sending a communication signal to at least one receiving device. The communication signal corresponds to an orthogonal frequency division multiple access, OFDMA, signal being communicated through at least one OFDMA frame (300) comprising a frame header (301), a first zone (320) having assigned a first set of transmission parameters and a second zone (330) having assigned a second set of transmission parameters. The first zone (320) comprises a first zone header (321) indicating the first set of transmission parameters and the second zone (330) comprises a second zone header (331) indicating the second set of transmission parameters. The data transmission apparatus is configured to assign a data transmission bandwidth to the at least one receiving device in at least one of the first zone and the second zone and to transmit an assignment signal to the at least one receiving device by means of which the data transmission bandwidth is assigned to the receiving device. The data transmission apparatus is configured to use the assigned first zone (320) or second zone (330) for both receiving and sending data to the at least one receiving device. Thus, the data transmission and signalling overhead in an OFDMA frame is reduced.

摘要： The present invention relates to the technical field of FD capable wireless communication devices. The invention is about resolving a collision between a transmission of one device and a simultaneous transmission of another device. The device is configured to interrupt its transmission, determine a negotiation signal, and determine at least one available resource to occupy with the negotiation signal during a negotiation period. Further, the device is configured to transmit the negotiation signal on the at least one available resource and simultaneously receive a negotiation signal on another resource from at least one other device during the negotiation period. Then, the device is configured to decide, based on all negotiation signals, whether to retransmit the interrupted transmission after the negotiation period.
