摘要： A data transmission apparatus (100) for sending a communication signal to at least one receiving device (200A, 200B), a communication device (200A, 200B) for receiving a first communication signal from a data transmission apparatus (100) and for sending a second communication signal to the data transmission apparatus (100), an apparatus (400) for analyzing a communication signal and a frame structure (300) for data transmission between a data transmission apparatus (100) and at least one communication device (200A, 200B) are provided. 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 proposes a receiver (1) and method for decoding data packets. A receiving unit (5) of the receiver (1) receives a data packet P1, which contains a MAC header. A soft decoder (3) of the receiver (1) decodes the data packet P1 to obtain soft values of the data packet P1, and an error checking module (2) of the receiver performs a cyclic redundancy check, CRC, on the data packet P1. If the CRC on the data packet P1 fails, a hard decoder (4) of the receiver (1) performs a first hard decision on the soft values of the data packet P1 corresponding to the MAC header of the data packet P1, and a controller (8) of the receiver (1) determines based on the result of the first hard decision, whether soft values of a previous transmission of the data packet P are stored in a memory (6) of the receiver (1), and combines said stored soft values with the soft values of the data packet P1 to obtain combined soft values. Finally, the error checking module (2) performs a CRC based on the combined soft values.
