Abstract: A device for near-field communication (NFC) and wireless power reception (WPR) using a magnetic field. The device has an antenna resonant circuit. The antenna resonant circuit includes an antenna for magnetic flux of the magnetic field to flow therethrough, to thereby receive a NFC signal during the NFC and receive wireless power during the WPR, and a multi-Q antenna matching circuit configured to adjust an impedance of the antenna to thereby adjust a quality factor (Q-factor) of the antenna resonant circuit. The multi-Q antenna matching circuit is configured to switch between a high-Q mode for the WPR and a low-Q mode for the NFC, based on whether strength of the magnetic field is larger than a predetermined threshold. The device may also include two separate antenna resonant circuits, of which the Q-factors are respectively no higher than 25 and no lower than 50.

Abstract: A device may receive signal information associated with a wireless signal or charge information associated with a charge level. The signal information may indicate a signal strength of the wireless signal. The charge information may indicate the charge level of a battery of the device. The device may determine whether the signal strength or the charge level satisfies a threshold.

The LTE category may be different from a default LTE category of the device and may define an uplink/downlink capability specification. The device may attach to a network in association with configuring the parameter or the setting to cause the device to operate according to the LTE category.

Abstract: A cover for protecting an audio port of an electronic device is provided. The cover includes a check valve, a bellows, and an air vent. The check valve moves between a first position to allow audio pressure to exit the audio port and a second position to fluidly seal the audio port. The bellows at least partially surround the audio port when the cover is attached to the electronic device and move the check valve from the first position to the second position in response to a pressure exerted on the bellows. The air vent is attached to the bellows and allows audio pressure to pass through the air vent and to restrict passage of at least some water through the air vent.

The user apparatus includes a setting information reception unit that receives, from the first base station, first setting information for instructing whether to report uplink transmission power information to the first base station, and second setting information for instructing whether to report uplink transmission power information to the second base station. A report control unit reports uplink transmission power information to the first or second base station when detecting a report trigger for performing reporting of the uplink transmission power information. When the report control unit detects a report trigger for a specific base station for which it is instructed not to perform reporting of the uplink transmission power information, the uplink transmission power information is reported to another base station.

Abstract: A user equipment (UE) may compute uplink power control levels as a function of a downlink signal to noise ratio (SNIR). For example, the UE may determine an uplink transmit power level by summing a full power control (FPC) transmit power level, a product of a first adjustment factor (?) and the downlink SNIR, and a negative of a second adjustment factor (?2) when the product of the first adjustment factor (?) and the downlink SNIR is greater than or equal to the second adjustment factor (?2). A UE may also compute an uplink power control level as a function of target and/or current interference levels associated with neighboring base stations. A UE may also iteratively reduce a transmit power level until an interference level experienced by a neighboring base station has fallen below a threshold.

Abstract: Disclosed are a wireless transmitter and a reference signal transmission method that improve channel estimation accuracy. In a terminal (100), which transmits a reference signal using n (n is a non-negative integer 2 or greater) band blocks (which correspond to clusters here), which are disposed with spaces therebetween in a frequency direction, a reference signal controller (106) switches the reference signal formation method of a reference signal generator (107) between a first formation method and a second formation method based on the number (n) of band blocks. In addition, a threshold value setting unit (105) adjusts a switching threshold value based on the frequency spacing between band blocks. Thus, the reference signal formation method can be selected with good accuracy and, as a result, channel estimation accuracy is further improved.
