  • Patent number: 10087694
    Abstract: A hanger running tool for a hanger includes an outer sleeve and an inner driving sleeve. The outer sleeve is configured to engage and couple the hanger running tool to the hanger, and the inner driving sleeve is selectively axially movable within the outer sleeve for engagement with the hanger to prevent relative rotation between the hanger running tool and the hanger.

  • Patent number: 8145127
    Abstract: The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (315) an uplink scheduling grant at a user equipment (120), establishing (320) a desired power level based on at least the uplink scheduling grant, and setting (325) hardware power settings based on the desired power level. The method may also include transmitting (330) data in a first subframe at a first power level based on the hardware power settings, measuring (335) the first power level in the first subframe, and determining (340) a difference between the desired power level and the measured first power level. The method may additionally include modifying (345) the hardware power settings based on the difference and transmitting (350) at a second power level based on the modified hardware power settings in a next transmission corresponding to the transmission in the first subframe.

  • Patent number: 8140102
    Abstract: The present disclosure describes a method and apparatus for transmit power calibration in a frequency division multiplexed wireless system (100). The method may include receiving (320), at a user equipment (120), a signal from a base station (130) in a frequency division multiplexed wireless system and mapping (330), in response to receiving the signal from the base station, a power control calibration region to an uplink symbol in a subframe to establish a mapped uplink symbol using predetermined criteria. The method can also include calibrating (350) a transmit power based on transmission in the calibration region and transmitting (360) data at the calibrated transmit power on at least one other symbol following the mapped uplink symbol.

  • Publication number: 20070173260
    Abstract: A method in a wireless communication network infrastructure scheduling entity, including allocating a radio resource to a schedulable wireless communication entity in the wireless communication network, the radio resource allocated based on a maximum power available to the schedulable wireless communication entity for the radio resource allocated, the radio resource allocated based on an interference impact of the schedulable wireless communication entity operating on the radio resource allocated.

  • Publication number: 20070155335
    Abstract: A method for data rate selection of a data transmission on a wide band code division multiple access (WCDMA) radio frequency (RF) channel in a portable communication device (100) is provided. The portable communication device (100) has transmitter circuitry (108) which includes a power amplifier (250). The method includes the steps of determining a power backoff requirement for the power amplifier (250) for a data transmission on a WCDMA channel (320) and selecting a transport format combination (TFC) for the data transmission in response to the power backoff requirement (324).
