Abstract: A coding and modulation apparatus and method are presented. The apparatus comprises an encoder that encodes input data into cell words, and a modulator that modulates said cell words into constellation values of a non-uniform constellation. The modulator is configured to use, based on the total number M of constellation points of the constellation, the signal-to-noise ratio SNR and the number n of the dimension of the constellation, an n-dimensional non-uniform constellation from a group of constellations, wherein each constellation point of an n-dimensional constellation diagram is defined by an n-tupel of constellation values, said n-tupel of constellation values defining parameter settings of a transmission parameter used by a transmission apparatus for transmitting a transmission stream obtained by conversion of said constellation values. Further, the modulator is configured to use a constellation having a total number M of constellation points of the constellation and a number n of the dimension of the constellation which fulfill the condition that log2(M)/n*2 is a non-integer number.

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.

Abstract: A first communication device for communicating with a second communication device over a link that is utilized at the substantially same time and with the substantially same frequency resource by a pair of further communication devices. The first communication device comprises one or more antenna arrays with which beamforming can be performed, a control unit configured to apply beamformers to control beamforming by the one or more antenna arrays, and an interference alignment module configured to determine whether at least one of the beamformers satisfies an interference condition such that a level of interference leaked to the further communication devices by the first communication device is below a defined threshold, and if available, select the at least one beamformer for communicating with the second communication device. The interference condition is based on channel characteristics between the first communication device and at least one of the further communication devices and non-reciprocity mismatch.
