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.

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 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 communication device, e.g. an access point, for RF-based communication with another communication device, e.g. a station, comprises antenna circuitry configured to transmit and receive RF signals and beamforming circuitry configured to perform beamforming. The beamforming circuitry controls the antenna circuitry to transmit data, in a beacon transmission phase prior to the beamforming training phase, using a set of third directive transmit beams in subsequent time slots and to listen, in the beamforming training phase, using a set of first directive receive beams in subsequent time slots that is different from the set of third directive transmit beams.

Abstract: Communication device for communicating within a group of communication devices. The communication device comprising circuitry configured to listen to a training and control period of a further communication device which is acting as a wireless network coordinator of a further group of communication devices and transmits frames with a succession of directive beams, each identified by a transmit sector and to generate reception quality information associating each transmit sector with a quality indicator indicative of a reception quality of the received frames. Further, the circuitry is configured to obtain scheduling information from the further communication device including at least one scheduled data transfer period with transmit sector information associated therewith, and to generate scheduled data transfer periods for the group of communication devices based on the reception quality information and the scheduling information, including the transmit sector information, such that interference levels at the further communication device and/or another communication device are minimized.
