Abstract: A communication device (1) for RF-based communication with another communication device (2) comprises an antenna circuitry (10) configured to transmit and receive RF signals and beamforming circuitry (11) configured to perform beamforming and to control the antenna circuitry in a beamforming training phase to transmit and/or receive RF signals using one or more selected directive beams. The beamforming circuitry (11) is configured to perform beamforming training by controlling the antenna circuitry i) to transmit data using at least one first directive transmit beam, wherein the other communication device (2) is configured to listen using a first directive receive beam, said data including a second transmit beam information, and ii) to subsequently listen using a predetermined second directive receive beam for a response from the other communication device (2), which is configured to transmit, if the data transmitted in step i) have been received, a response using a second directive transmit beam indicated by the second transmit beam information.

Abstract: A communication device and method are presented that support the use of both uniform and non-uniform constellations and provide a reasonable solution for signaling. Capability information is transmitted, said capability information indicating if non-uniform transmission constellations are supported by the mapping circuitry on the transmitter side and/or if non-uniform reception constellations are supported by the demapping circuitry on the receiver side.

Abstract: A WiFi communications mechanism in which simultaneous transmission is negotiated and beamforming communications performed towards at least one station (STA), while nulling is performed towards one or more other access points (APs) to reduce interference. Omni-directional transmissions are utilized in a manner to overcome preamble interferences, which is used in combination with synchronizing symbol intervals to eliminate interference from symbol transitions. The enhanced simultaneous transmission protocol allows two APs to transmit simultaneously without interfering with one another.

Abstract: A coding and modulation apparatus and method are presented, particularly for use in a system according to IEEE 802.11. The apparatus comprises an encoder configured to encode input data into cell words according to an LDPC code and a modulator configured to modulate said cell words into constellation values of a non-uniform constellation and to assign bit combinations to constellation values of the used non-uniform constellation. The modulator is configured to use a non-uniform constellation and bit labeling from one of the several groups of constellations, which constellation show quadrant and octant symmetry.

Abstract: The improved beamforming devices for communication systems operating in the mm-wave spectrum are particularly designed for antenna architectures consisting of antenna arrays, comprising multiple antenna array elements. The disclosed approaches comprise intelligent two stage searches, wherein information from the first stage is used in the second stage. This significantly reduces the computational complexity compared to the known approaches, with minimal loss in performance.

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: Transmitter having multiple transmit antennas for transmitting two or more streams. The transmitter comprises an encoding circuitry configured to perform space-time block encoding to obtain for at least one of the two or more streams a pair of space-time encoded streams. Further, a mapping circuitry is configured to assign each stream of each pair of space-time encoded streams to a transmit antenna of the multiple transmit antennas for wirelessly transmitting the two or more streams. Finally, a control circuitry is configured to adjust one or more parameters of the mapping circuitry in order to achieve a defined channel characteristic between the transmitter and a receiver.
