Disclosed is a wireless signal receiving device and method capable of making different adjustments for different kinds of wireless communication to configure the device itself adaptively. The device includes an analog-front-end receiving circuit and a media access control (MAC) and post-processing circuit. The analog-front-end receiving circuit receives a first (second) communication signal through first (second) wireless communication in a first (second) duration and then generates a first (second) reception signal according to the first (second) communication signal. The MAC and post-processing circuit adjusts at least one parameter of the first (second) wireless communication according to updated setting of the first (second) wireless communication and thereby configures the device adaptively, wherein the updated setting of the first (second) wireless communication is determined according to the first (second) reception signal or first (second) subsidiary information dependent on the first (second) wireless communication.

A method and apparatus are provided for determining, by a wireless power transmitter, whether a wireless power receiver is removed from a wireless power network managed by the wireless power transmitter. The method includes transmitting a command signal to report power information of the wireless power receiver at stated periods; determining whether a report signal corresponding to the command signal is received from the wireless power receiver; and determining that the wireless power receiver is removed from the wireless power network, if the report signal is not received after transmitting the command signal a predetermined number of times at the stated periods.

In a wireless communication system, a mobile terminal providing a web service receives information about a web page for a web service from a mobile terminal, receives at least one embedded object included in the web page from a web server, sets a Discontinuous Reception (DRX) interval for the mobile terminal based on a size of the at least one embedded object, transmits information about the set DRX interval to the mobile terminal, and transmits the at least one embedded object to the mobile terminal at a time the set DRX interval ends.

In embodiments of wireless radios managed based on proximity, a mobile device, such as a mobile phone, tablet computer, or other portable device can be implemented for multiple, different wireless communications. A mobile device can include a first radio system for a first wireless communications technology, and a second radio system for a second wireless communications technology. A connection manager determines, based on the first wireless communications technology, whether the mobile device is in an area that is proximate an endpoint implemented for the second wireless communications technology. The connection manager can turn-on the second radio system to enable wireless communication with the endpoint when the mobile device is in the area proximate the endpoint. Alternatively, the connection manager can turn-off the second radio system and conserve power that would otherwise be utilized to scan for the endpoint when the mobile device is not in the area proximate the endpoint.

The present disclosure relates to a sensor network, Machine Type Communication (MTC), Machine-to-Machine (M2M) communication, and technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as a smart home, a smart building, a smart city, a smart car, a connected car, healthcare, digital education, smart retail, security and safety services. A method and an apparatus for controlling aperiodic traffic in an electronic device are provided. The method includes determining a delay allowed time for first traffic associated with the first application based on a prediction time of generation of second traffic associated with a second application and processing the first traffic associated with the first application based on the delay allowed time.

Provided is a wireless communication terminal. The wireless communication terminal includes: a transceiver configured for transmitting/receiving a wireless signal; and a processor configured for controlling an operation of the wireless communication terminal. The transceiver receives a first frame indicating that there is data to be transmitted from a base wireless communication terminal to a plurality of wireless communication terminals including the wireless communication terminal and receives data based on the first frame. The base wireless communication terminal is any one wireless communication terminal different from the plurality of wireless communication terminals.

A method includes when a terminal needs to execute a circuit switched service again after completing the execution of the circuit switched service once, the terminal executes the circuit switched service again instead of immediately returning to a first network, and then returns to the first network when a preset condition is met.

The present invention relates to a technology for managing discontinuous reception (DRX). DRX cycles of different cycle lengths are configured according to service types of UE. If it is identified that the user equipment (UE) initiates a voice service, a relatively short first long DRX cycle is configured for the UE or the UE is instructed to deactivate DRX; and if it is identified that the UE does not perform a voice service, a relatively long second long DRX cycle is configured for the UE. The UE performs corresponding receiver on/off control according to the configured long DRX cycle, so as to receive downlink data or hibernate. According to the solution provided in the present invention, a DRX cycle of UE can be flexibly configured, so that a better balance between power consumption reduction of the UE and user experience improvement can be achieved.

Methods, systems, and apparatuses for wireless communication are disclosed. In one aspect, a user equipment (UE) determines to perform a synchronization procedure and receives at least one synchronization signal. The UE may generate a detection metric based at least in part on the at least one synchronization signal and compare the detection metric or detection metrics accumulated since determining to perform the synchronization procedure with a detection threshold. The detection threshold may be associated with the at least one synchronization signal utilized to determine whether the synchronization procedure can be terminated prior to receiving a predetermined number of synchronization signals. The UE may continue or terminate the synchronization procedure based at least in part on a result of the comparison.
