Abstract: A communication device for RF-based communication with another communication device comprises antenna circuitry configured to transmit and receive RF signals, and beamform-ing circuitry configured to perform beamforming and to carry out a beam training procedure for finding a beam for use in transmitting and/or receiving RF signals and/or for channel estimation. The beamforming training procedure comprises at least two stages during which training signals are transmitted using different beams, wherein first beams used in a first stage have a larger beam sector than second beams used in a second stage and wherein the second beams are selected by forming a virtual best sector based on an evaluation of a predetermined metric obtained for the first beams in the first stage.

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 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.
