Wireless communication device

According to one embodiment, a wireless communication device includes: a communicator and controlling circuitry. The communicator is configured to simultaneously communicate a first frame and a second frame, and after the first frame and the second frame are communicated, communicate a third frame indicating acknowledgement of the first frame and a fourth frame indicating acknowledgement of the second frame. The controlling circuitry is configured to control to prevent the third frame and the fourth frame from being simultaneously communicated.

Full Duplex Cable Communication

Example embodiments describe a controller comprising means for performing i) discovering a mapping between receive analogue to digital converters, RxADCs, of a full duplex node (100) and cable modems (111-113, 121-123, 131-133, 141-143) connected to the full duplex node; and wherein the cable modems share a common communication bandwidth; and ii) determining, based on the mapping, sounding groups (152, 162) by grouping cable modems (111-131, 121-123) mapped to a same RxADC (151) into a respective sounding group (152); and wherein a sounding group is indicative for an upper bound of possible interfering cable modems.

Method, system and apparatus of time-division-duplex (TDD) uplink-downlink (UL-DL) configuration management

Some demonstrative embodiments include devices, systems and/or methods of Time-Division Duplexing (TDD) Uplink-Downlink (UL-DL) configuration management. For example, a node may communicate a message including a cell identifier identifying a first cell controlled by the node, and a TDD configuration update to update at least one other node, which controls at least one second cell, with a TDD UL-DL configuration allocated by the node for communication within the first cell.

Virtual time-domain multiplexing for reference signals and data with modified cyclic prefix

Aspects of the disclosure relate to methods and apparatus of time-domain multiplexing (TDM) for reference signals (RS) and data using a modified cyclic prefix. A reference signal (RS) and data are multiplexed either in a single symbol or in two time consecutive symbols that respectively including the RS and data. The cyclic prefix (CP) is added to the single symbol using a portion of the RS or to a first symbol of the two time consecutive symbols using a portion of the RS. The CP may be copied from the RS or the end of the symbol, but not the data, in a manner that affords a virtual Time Division Multiplexing (TDM) of the RS and data before discrete Fourier transform (DFT) spreading is performed in a transceiver to provide lower peak to average power ratios and no Inter-symbol interference.

RECEPTION APPARATUS AND METHOD, TRANSMISSION APPARATUS AND METHOD, AND PROGRAM
20190279472 · 2019-09-12 ·

The present disclosure relates to a reception apparatus and method, a transmission apparatus and method, and a program, capable of obtaining desired communication quality. Under the control of a central control unit, a tactile signal generation unit generates a tactile signal of a necessary number. Under the control of the central control unit, a header generation unit generates header information including the presence or absence of the tactile signal (that is, information indicating whether or not the tactile signal is to be used for each of vibration units as information associated with the vibration unit that uses the tactile signal), the delay amount, and the magnitude. A signal coupling unit adds header information to each of the tactile signals from the tactile signal generation unit, and performs time-division multiplexing on each of the tactile signals to which the header information has been added. The present disclosure can be applied to a tactile presentation system that vibrates a wearable reception apparatus including the vibration unit, for example.

Uplink data fragmentation for multi-user networks

An apparatus for wireless communication includes data defragmentation logic configured to receive, during a first transmit opportunity, a first data packet from a first device and a second data packet from a second device. The first data packet includes a first data fragment, and the second data packet includes a second data fragment. The apparatus also includes block acknowledgement generation logic configured to generate a block acknowledgement frame including a first block acknowledgement bitmap and a second block acknowledgement bitmap. The first block acknowledgement bitmap indicates at least the first data fragment received from the first device, and the second block acknowledgement bitmap indicates at least the second data fragment received from the second device. The apparatus further includes a wireless interface configured to transmit the block acknowledgement frame to the first device and to the second device.
