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: 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 a low density parity check code, LDPC, 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, wherein said modulator is configured to use, based on the PHY mode, the total number M of constellation points of the constellation and the code rate, a particular non-uniform constellation.

Abstract: A probabilistic signal point shaping device comprises circuitry configured to map data blocks of input bits of an input bit stream onto mapping symbols, wherein said mapping symbols are distributed according to a predetermined probability distribution and represented by complex-valued signal points or non-uniformly spaced amplitude levels, assign bit labels to said mapping symbols, determine redundancy bits from the bits of said bit labels, transform said redundancy bits into a redundancy rule, and apply the redundancy rule to the mapping symbols to obtain output symbols.

Abstract: A method for determining a location of a client device in a wireless network including the client device and at least three network devices, each of the three network devices having a known location comprises a pairwise exchanges of messages between at least three different pairs of network devices of said at least three network devices. In the pairwise exchange messages, wherein in a pairwise message exchange time difference information of the time difference between reception of a message and subsequent transmission of a message is included. This time difference information is used in the determination of the location of the client device.

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 controller configured to apply beamformers to control beamforming by the one or more antenna arrays, and circuitry 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.
