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 provides devices and methods for enabling Hybrid Automatic Repeat Request (HARQ) in wireless communication technologies, particularly in Next Generation WiFi. A particular device of the invention for supporting such HARQ for Wi-Fi is configured to transmit, to a receiver, an aggregated data unit (e.g. A-MPDU) including at least one data unit (e.g. MPDU). The device is further configured to scramble the aggregated data unit by performing scrambling and encode the scrambled aggregated data unit by using Forward Error Correction (FEC). Further, the device is configured to retransmit to the receiver, if a decoding of at least one data unit failed at the receiver, at least a part of the aggregated data unit including the at least one failed data unit. Thereby, the device is configured to scramble and encode the at least one failed data unit in the retransmitted part by performing scrambling based on the same scrambling seed and by using FEC with the same FEC outputs that were used for scrambling and encoding said data unit in the aggregated data unit. The receiver may thus decode the at least one retransmitted data unit and soft combine it with the previously received failed data unit.
