Abstract: The present disclosure provides an occupation control method for a camera application including: when a camera application is occupied by a first application running in the foreground, if it is determined that a terminal device is in a preset first operation state, detecting whether the first application sends a camera data request message; if so, sending to the camera application a message for delaying shutdown for a first duration and detecting whether the state of the terminal device is switched from the first operation state to a second operation state within the first duration; if the state is not switched to the second operation state and it is detected the first application continues to send the camera data request message, detecting whether the first application enables a function related to the camera data request, and if not, controlling the first application to release the occupation of the camera application.

Abstract: Remote actuation of machines or machine systems is realized by a system for coupling a radiobeacon to a smart device and in turn to a broader network. The smart device is configured as a proximity-actuated “community nodal device” by an application that operates as part of the system. The community nodal device is given instructions to function as a “soft switch”: to automatically “upswitch”, amplify, and broadcast low energy, local area radiobeacon “messages” to a cloud-based server, where the message is interpreted according to rules or policies established by an operator, and a command is transmitted for execution to a remote device. Conventional smart devices generally discard data not addressed to the owner of the smart device.

Abstract: Systems and methods are described herein for adaptive pointing operations of a mobile antenna system that can be used to provide communication with a target satellite over a large geographical area, while also satisfying interference requirements with one or more other satellites. In particular, the adaptive pointing operations described herein control pointing of a beam of the antenna system towards the target satellite in a manner that takes into consideration the interference requirements of the other satellites. In some embodiments, the mobile antenna system can provide non-interfering communication with the target satellite, over the entire or substantially the entire coverage area (or footprint) of the target satellite. In doing so, services such as Internet, telephone and/or television services provided by the target satellite can be delivered to users throughout most or all of the satellite's coverage area, while also satisfying interference requirements with other satellites.

Abstract: A method and a spectrum owner system are described. The spectrum owner system records, in a distributed ledger network, a list of spectrum resources licensed from a regulatory authority system to the spectrum owner system. The spectrum owner system receives an authorization request for a spectrum allocation of spectrum resources, where the spectrum allocation includes at least a desired interval of time for usage of the spectrum resources by a radio access network of a spectrum renter, a desired location for usage of the spectrum resources by the radio access network, and additional characteristics of the spectrum resources. The spectrum owner system negotiates agreement terms for the desired spectrum allocation; and records, in the distributed ledger network, a hash of the spectrum allocation, where the spectrum allocation enables the radio access network of the spectrum renter to provide radio access services to wireless network devices.

Abstract: A control device may be configured to transmit messages using an adaptive transmit power. The control device may determine a transmit power for transmitting the message based on a command in the message. The control device may determine a transmit power based on a change in lighting intensity caused by the command. The transmit power may be greater when the change in lighting intensity is above a threshold than when the change in light intensity is below the threshold. The control device may determine whether the message was successfully received based on the receipt of an acknowledgement message. The control device may increase the transmit power when the message fails to be received and retransmit the message including the command at an increased transmit power. The control device may store (e.g., learn) the increased transmit power for later use.

Abstract: Systems, methods, and instrumentalities are disclosed for dynamic interference management in NR dynamic TDD systems. A first WTRU (e.g., an aggressor WTRU) may receive downlink control information (DCI). The first WTRU may determine a first priority associated with the first WTRU. The first WTRU may determine the first priority based on one or more of the DCI or a logical channel prioritization. The first WTRU may receive an interference measurement reference signal (IMRS) transmission from a second WTRU (e.g., a victim WTRU). The first WTRU may measure the received IMRS transmission. The first WTRU may determine a second priority associated with a downlink payload of the second WTRU. The first WTRU may determine that the second priority is greater than the first priority. The first WTRU may adjust an uplink transmission power of the first WTRU, for example, based on the first priority and the second priority.

The invention also relates to a system comprising a terminal and a gateway, and to a method for operating a terminal.
