Energy per resource element determination for sub-band full-duplex communication
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine an energy per resource element (EPRE) value for a slot based at least in part on whether the slot is associated with a half-duplex configuration or a full-duplex configuration, wherein the EPRE value is a first value when the slot is associated with the half-duplex configuration and a second value when the slot is associated with the full-duplex configuration; and perform a communication in the slot in accordance with the EPRE value. Numerous other aspects are provided.
Data processing apparatus and data processing method
The present technique relates to a data processing apparatus and a data processing method each of which enables a burden imposed on processing on a reception side to be reduced. A data processing apparatus produces signaling containing a Null cell number exhibiting the number of Null cells of cells of a sub-frame included in a physical layer frame, and processes the signaling so as for the signaling to be contained in a preamble of the physical layer frame, thereby enabling a burden imposed on processing on a reception side to be reduced. The present technique, for example, can be applied to data transmission complying with the broadcasting standards such as ATSC3.0.

Multi-beam MIMO antenna systems and methods
This application proposes multi-beam antenna systems using spherical lens are proposed, with high isolation between antenna ports and compatible to 2×2, 4×4, 8×8 MIMO transceivers. Several compact multi-band multi-beam solutions (with wideband operation, 40%+, in each band) are achieved by creating dual-band radiators movable on the track around spherical lens and by placing of lower band radiators between spherical lenses. By using of secondary lens for high band radiators, coupling between low band and high band radiators is reduced. Beam tilt range and side lobe suppression are improved by special selection of phase shift and rotational angle of radiators. Resultantly, a wide beam tilt range (0-40 degree) is realized in proposed multi-beam antenna systems. Each beam can be individually tilted. Based on proposed single- and multi-lens antenna solutions, cell coverage improvements and stadium tribune coverage optimization are also achieved, together with interference reduction.
WIRELESS COMMUNICATION SYSTEM, BASE STATION DEVICE AND WIRELESS COMMUNICATION METHOD
In a wireless communication system in which propagation delays between a plurality of terminal station devices and a base station device, which use time division multiplexing in a duplex operation system, are different from each other, at least one of the base station device or the terminal station devices includes a delay calculating unit that calculates the propagation delay for each of the terminal station devices, and the base station device includes a control unit that changes a frame configuration such that a standby time required for switching between an uplink frame and a downlink frame is shortened in accordance with the propagation delay for each of the terminal station devices. In accordance with this, a surplus standby time can be shortened, and a transmission capacity can be improved.
AIR-CONDITIONING SYSTEM, AIR CONDITIONER, AND METHOD FOR RECOGNIZING AIR CONDITIONER
A recognition process for an air conditioner is executed while the deterioration of the environment due to stoppage of the air conditioner is suppressed. In an air-conditioning system in which a plurality of air conditioners belonging to an identical refrigerant system are connected through a communication line inside the identical system and a plurality of air conditioners belonging to different refrigerant systems are connected through a communication line outside the different systems, for the plurality of air conditioners belonging to the identical refrigerant system, a recognition process is executable while an air-conditioning control process is executed by transmission through at least the communication line inside the system.
Coexistence of wireless sensor networks with other wireless networks
A method for communicating in a wireless sensor network (WSN) is described. Using control logic, a first wireless transceiver is caused to transmit a wireless packet to a node in a wireless sensor network. The control logic bases its causing on a transmission coinciding with a break in transmission for a second wireless network, such that the transmission from the first wireless transceiver does not coincide with transmissions made on the second wireless network. Time synchronized channel hopping (TSCH) slot frames for wireless packet transmission in the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing TSCH. Wake up sequence transmissions for the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing coordinated sampled listening (CSL).
Data transmission method, apparatus and system
The present invention provides a data transmission method, apparatus and system. The method includes: in a detection period, receiving a first pilot signal sent by an unmanned aerial vehicle (UAV), the first pilot signal being a downlink signal obtained by modulating a useful signal at a preset candidate frequency, and the preset candidate frequency including a frequency in a same frequency band and/or different frequency bands; determining a downlink operating frequency from the preset candidate frequency according to the first pilot signal; sending a first feedback signal to the UAV, the first feedback signal including information about the downlink operating frequency; and receiving downlink data sent by the UAV and modulated at the downlink operating frequency. In this way, frequency detection in a same frequency band and/or across frequency bands is implemented to select an optimal preset candidate frequency as an operating frequency, so that data transmission between a UAV and a remote control is more stable, interference from an external signal is reduced, and quality of data transmission between the UAV and a ground end is improved.
MULTIPLE TRANSMISSION TIME INTERVAL COORDINATION WITH TIME DIVISION DUPLEXING
Methods, systems, and devices for wireless communication are described. Data may be received during transmission time intervals (TTIs) that have a short duration relative to other TTIs. The short-duration TTIs may occur within or overlap a longer duration TTI, such as a subframe. Feedback responsive to the data may be generated and assigned for transmission during an uplink TTI according to a feedback timing or delay, which may be selected to reduce latency or balance the payload size of uplink messages sent during the assigned uplink TTI. Data and feedback assignments in short-duration TTIs may be configured based on a time division duplexing (TDD) configuration for some TTIs (e.g., subframes). TTIs that are a Long Term Evolution (LTE) subframe, an LTE slot, and a duration of two LTE symbol periods may be supported. Portions of special TTIs may be used for transmissions according to shorter-duration TTIs.
