LOW-POWER MODES FOR VULNERABLE ROAD USER EQUIPMENT
The present disclosure provides technologies and techniques for power optimization of vulnerable road user (VRU) devices in Intelligent Transportation Systems (ITS)/Vehicle-to-Everything (V2X) systems/networks, Internet of Things (IoT) devices, and/or other small form-factor devices. The power optimizations involve disabling or placing the communications functionality of a device in a sleep or inactive mode in situations where such functionality is not needed. The power optimization techniques include medium access control (MAC) optimized discontinuous reception (DRX) configurations, location-based communication, wake-up signaling communication, contextual activation and parameterization of device communication, slot reservation communication. Additional aspects of devices and communication configurations and arrangements may be described.
Low-power radio-frequency receiver
A motorized window treatment provides a low-cost solution for controlling the amount of daylight entering a space through a window. The window treatment includes a covering material, a drive shaft, at least one lift cord rotatably received around the drive shaft and connected to the covering material, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions, which helps to minimize motor usage and conserve battery life if a battery is used to power the motorized window treatment. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors to save energy, or may also be controlled in response to an infrared or radio-frequency remote control.
Wireless battery management system, node for wireless communication, and method of assigning slot
Disclosed are a wireless battery management system, a node for wireless communication, and a method of assigning slot, which respectively assign dedicated slots having different time intervals to monitor nodes to support smooth and stable communication between the monitor nodes and a manager node. The wireless battery management system includes a manager node checking number of monitor nodes joining in a short-range wireless network for battery management, dividing a transmission slot, assigned for data transmission, by the number of monitor nodes to generate a plurality of dedicated slots, and respectively assigning the plurality of dedicated slots to the monitor nodes and a monitor node collecting battery data and transmitting the collected battery data to the manager node during an assigned dedicated slot.
INFORMATION PROCESSING DEVICE, AND INFORMATION PROCESSING METHOD USING MULTIPLE MULTIPLEXING METHODS
An information processing device includes a control unit. A first device that transmits data to the information processing device has a multiplexing function for multiplexing and transmitting data from a plurality of devices including the first device to the information processing device. The control unit provided in the information processing device performs control to tell the first device having the multiplexing function a multiplexing method for notification information and presence of data addressed to the first device. The notification information indicates that the first device has shifted from a functional suspension state to a data receivable state. The information processing device can reduce power consumption.
MOTORIZED WINDOW TREATMENT
A motorized window treatment for controlling the amount of daylight entering a space through a window includes a covering material, a drive shaft, and a motor coupled to the drive shaft for raising and lowering the covering material. The window treatment also includes a spring assist unit for assisting the motor by providing a torque that equals the torque provided by the weight on the cords that lift the covering material at a position midway between fully-open and fully-closed positions to minimize motor usage and conserve battery life. The window treatment may comprise a photosensor for measuring the amount of daylight outside the window and temperature sensors for measuring the temperatures inside and outside of the window. The position of the covering material may be automatically controlled in response to the photosensor and the temperature sensors, or in response to an infrared or radio-frequency remote control.
ADJUSTING A PHYSICAL UPLINK CONTROL CHANNEL (PUCCH) FORMAT IN A WIRELESS COMMUNICATION NETWORK
Embodiments of the present disclosure provide a method and system for adjusting a physical uplink control channel (PUCCH) format in a wireless communication network. In particular, the method is implemented for adjusting a PUCCH format in an uplink transmission from a terminal device to a network device in a wireless communication network. The method comprises: using a first PUCCH format having a first duration for a service between the terminal device and the network device; and using (804) a second PUCCH format having a second and different duration for the service of the terminal device responsive to a determination that the first PUCCH format is in need of change based on one or more events.
OPERATION WITH POWER SAVING IN CONNECTED MODE DISCONTINUOUS RECEPTION (C-DRX)
A user equipment (UE), a base station (BS), and a method for managing UE operation in C-DRX. The UE includes a transceiver configured to receive configurations for a drx-onDurationTimer, search space sets for reception of a PDCCH, a first set of CSI-RS resources, SS/PBCH blocks, and a PUCCH resources; and the PDCCH that provides a DCI format including a field indicating whether or not to start the drx-onDurationTimer. A processor is configured to determine an indication by the field to not start the drx-onDurationTimer, and determine reception occasions for the first set of CSI-RS resources during the ON duration. The transceiver is configured to receive the first set of CSI-RS resources or the SS/PBCH blocks during at least one of the reception occasions. The processor is also configured to determine a CSI report based on a reception occasion, which can be transmitted using the PUCCH resource during the ON duration.
TERMINAL, COMMUNICATION SYSTEM, COMMUNICATION METHOD AND STORAGE MEDIUM
Disclosed are a terminal, a communication system, a communication method and a storage medium. The terminal comprises a receiver and a processor, the receiver is configured to output, upon reception of a destination address in a data packet, a trigger signal; and the processor is configured to control, upon detection of the trigger signal and when the destination address is not the address of the terminal, the receiver to stop receiving the data packet. The present disclosure can effectively reduce power consumption of terminals.
Interfering device identification
Example methods and systems are disclosed to facilitate detection and identification of devices connected to a cellular network and that are causing interference to the cellular network. An example method may include receiving, by a serving base station of the device, a first set of information associated with data communications of a device utilizing a cellular network. The method may further include determining the device is an interfering device based on the first set of information associated with the data communication substantially corresponding with an interfering device profile, and in response tracking the device. During the tracking of the device, a second set of information associated with the data communications from the device may be obtained, and an interfering device type of the device may be determined based on the second set of information.
