  • Patent number: 9113416
    Abstract: At least one feature pertains to a method of communication that comprises aligning a measurement task that utilizes a resource within a user equipment, such that at least a portion of the measurement task is performed during a time that the resource is enabled in the user equipment, and executing the measurement task during the time that the resource is enabled in the user equipment. In one example, the measurement task may be a searcher task, the resource may comprise receiver circuitry, and the time that the resource is enabled corresponds to a DRX monitoring interval of a downlink channel, such as a high speed shared control channel. By aligning and executing the searcher task during the time that the resource is enabled in the user equipment, searcher overhead may be reduced. Reducing searcher overhead allows the user equipment to save power by disabling the receiver circuitry.

  • Publication number: 20140241179
    Abstract: Methods and apparatus of wireless communication include receiving channel information and performing a first network activity estimation using at least a portion of the channel information. The first network activity estimation provides a first network activity indication. Moreover, the methods and apparatus include performing a second network activity estimation using at least another portion of the channel information. The second activity estimation provides a second network activity indication. Also, the method and apparatus include aggregating the network activity indications.

  • Publication number: 20140146726
    Abstract: Methods and apparatus of controlling user equipment transmit power in a wireless communication system include communicating with a first base station and a second base station. Further, the methods and apparatus include establishing a high speed channel with one of the first base station or the second base station, wherein the one of the first base station or the second base station defines a high speed serving cell and a remaining one of the first base station or the second base station defines a non-high speed cell. Additionally, the methods and apparatus include ignoring a transmit power control command from the non-high speed cell when a high speed power control state applies to controlling a transmit power level.

  • Publication number: 20120120860
    Abstract: In a cellular communication system, apparatus and methods relating to a power-optimized demodulator front end (demfront) receiver subsystem of a user equipment (UE) can reduce power utilization by optimizing the operation of the demfront receiver subsystem. For example, in an aspect, the apparatus and methods include enabling a first receiver of a device for receiving a control channel on a downlink from a node, determining that the control channel schedules the device to receive data on the downlink, enabling a second receiver of the device that consumes more power than the first receiver to receive the data on the downlink, and re-enabling the first receiver for receiving the control channel on the downlink subsequent to receiving the data.
