Abstract: A transmission apparatus for use in a communication system comprises MAC layer processing circuitry and PHY layer processing circuitry. The MAC layer processing circuitry is configured to encode, on a MAC layer, N data units, each comprising payload data, into M parity units, each comprising parity data allowing the reconstruction of one or more erroneous data units among said N data units in a receiver apparatus, according to a parity rule, the N data units and the corresponding M parity units representing a parity block, and to form a MAC layer data stream from the data units and the parity units of the parity block. The PHY layer processing circuitry is configured to encode, on a PHY layer, bits of the MAC layer data stream into codewords of a code and to form a PHY layer data stream from the codewords.

Abstract: A transmitter transmits data using Orthogonal Frequency Division, OFDM, symbols. The transmitter comprising a forward error correction encoder configured to encode the data to form forward error correction encoded frames of encoded data cells, a service frame builder configured to form a service frame for transmission comprising a plurality of forward error correction encoded frames, a convolutional interleaver comprising a plurality of delay portions and configured to convolutionally interleave the data cells of the service frames, a modulation symbol mapper configured to map the interleaved and encoded data cells of the service frames onto modulation cells, and a modulator configured to modulate the sub-carriers of one or more OFDM symbols with the modulation cells. A controller is configured to form signalling data to be transmitted to include an indication of an identified first cell of a first of the forward error correction frame of a new service frame which can be decoded from cells received from the new service frame or the new service frame and one or more service frames following after the new service frame. By detecting the first cell of a first of the error correction encoded frames of a new service frame which does not have any data cells in one or more previous service frames as a result of the convolutional interleaving then a receiver, which has acquired the new service frame but none of the one or more previous service frames can decode this first forward error correction encoded frame of the new service frame and ignore the other forward error correction encoded frames earlier in the service frame. Therefore for example a receiver may power on or channels during a previous service frame and be directed to only decode a forward error correction encoded frame that it can decode.

Abstract: A communication device for RF based communication with another communication device, said communication device comprising circuitry configured to apply a fine timing measurement, FTM, procedure. The circuitry is configured to determine an FTM mode out of at least two different FTM modes, and to perform an FTM procedure to determine the round trip time, RTT, between the communication device and the other communication device, wherein the RTT is determined by evaluating a time information of a tap of the channel impulse response, wherein the tap used for the evaluation depends on the determined FTM mode.
