Systems, methods, and computer readable media for performing task assignment, completion, and management within a crowdsourced surveillance platform. A remote server may identify targets for image capture and may assign capture tasks to users based on travel plans of the user. Users may be assigned task to capture image of target locations lying along a travel path. The remote server may aggregate data related to the captured images and use it to update a map and log changes to the target location over time.

Techniques for operating cellular internet of things (IoT) devices under a public cellular carrier are disclosed. During an active connection, the cellular IoT device's radio-controlling application can collect radio metrics by tapping into the diagnostics interface of IoT device's cellular modem to collect data regarding accumulative signal strength, block/bit error rate, and/or round-trip latency for the session, etc. During the active connection, battery and environmental information as well as application-based information can be collected and sent to a remote computing device. In an example, the cellular IoT device can be given revised or refined values for use in timers, which may be used by the device to more efficiently use idle and/or power-save modes to reduce battery power consumption. Moreover, the use of the timers may be extended to devices distinct from the cellular modem, thereby increasing the utility of the timers and the functionality of the IoT device.

A communication apparatus comprises a first communication unit configured to connect to another communication apparatus and communicate by using a PCR (Primary Connectivity Radio) function, and a second communication unit configured to communicate with the other communication apparatus by using a WUR (Wake Up Radio) function. The communication apparatus stores, in a storage unit, a first transmission rate which is a transmission rate of the first communication unit used before the WUR mode is started, and sets the stored first transmission rate as a second transmission rate which is a transmission rate of the first communication unit used when the WUR mode has been ended.

Embodiments of this disclosure provide a signal quality information obtaining method, a device, and a system. One example method includes: a source network device obtains configuration information of an SRS of a terminal device and sends the configuration information of the SRS to a target network device and the terminal device. A first cell of the target network device monitors the SRS based on the configuration information of the SRS, and then the target network device sends, to the source network device, signal quality information of the SRS detected by the first cell. Correspondingly, the source network device receives, from the target network device, the signal quality information of the SRS detected by the first cell, where the first cell is a cell controlled by the target network device, the first cell is an energy-saving cell, and the energy-saving cell is a cell that does not send an SSB.

An active period that is expressed by a range of a count value t[x] and is a period during which communication of a packet with an outside is permitted and an inactive period that is expressed by a range of the count value t[x] and is a period during which communication of a packet with an outside is prohibited are defined in schedule data. A wireless communication interface communicates a packet with the outside during the active period. A power supply controller cuts off power supplied to the wireless communication interface during the inactive period. A synchronous controller updates a count value of a counter based on a synchronous data value in the received packet during a reception operation of the packet, define the synchronous data value based on the updated count value t[y] during a transmission operation of the packet, and store it in the packet to be transmitted.

The present disclosure relates to a communication method and system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The present invention presents a method for efficiently estimating a physical channel and, according to the present invention, a terminal of a communication system receives a synchronization signal from a base station, receives a broadcast channel from the base station, and can estimate the broadcast channel on the basis of the synchronization signal.

A system for communication is provided, where the system comprises a context broker configured to gather context information for use in managing a plurality of radios, a Wi-Fi radio manager configured to manage the plurality of radio managers using the context information, and a plurality of radios, where each of the plurality of radio managers is configured to manage one of the plurality of radios for communication with another electronic device.

Provided are a method by which a first device performs wireless communication, and a device for supporting same. The method can comprise the steps of: transmitting one or more reference signals (RSs) to a second device on the basis of first transmit power; receiving, from the second device, information related to a channel state measured on the basis of the one or more RSs; changing the first transmit power to second transmit power on the basis of the information related to the channel state; and transmitting the one or more RSs to the second device on the basis of the second transmit power.

Methods, systems, and devices for wireless communications are described to enable a mobile access node to enter a new power state based on detection of a second access node. The second access node may be detected by the mobile access node or a central unit (CU). The mobile access node or the CU may determine for the mobile access node to enter a new power state and may notify the other of the determination. The mobile access node may enter a lower power state if the second access node is within a defined proximity or if one or more thresholds are exceeded. The mobile access node may enter a higher power state if no other access nodes are within the defined proximity or if the one or more thresholds are not exceeded. Configuration parameters for a power state change procedure may be configured by control signaling from a CU.
