Abstract: A position estimation device for estimating the position of an initiator communication device comprises data obtaining circuitry configured to obtain path data of two or more paths of RF signals transmitted by a responder communication device, wherein RF signals of at least one path are reflected at a scatterer, said path data comprising, per path of an RF signal: path length information indicating the length of the propagation path of an RF signal from the responder communication device via a scatterer to the initiator communication device, angle of departure information indicating the angle of departure of an RF signal from the responder communication device, and angle of arrival information indicating the angle of arrival of an RF signal at the initiator communication device. The device further comprises processing circuitry configured to determine the position of the initiator communication device on the basis of the obtained path data.

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.
