  • Method and apparatus for back to back reselection scheduling upon cell reselection failure
    Patent number: 9723527
    Abstract: Methods and apparatus for wireless communication for improving back to back cell reselection that includes establishing that cell reselection to a primary candidate cell has failed. Afterwards, a UE determines if a set of predetermined conditions have been triggered and schedules cell reselection to a secondary candidate based on whether the set of predetermined conditions have been triggered.
    Type: Grant
    Filed: October 3, 2013
    Date of Patent: August 1, 2017
    Assignee: QUALCOMM Incorporated
    Inventors: Yi Su, Harish Venkatachari, Sundaresan Tambaram Kailasam, Uzma Khan, Preyas Devangbhai Desai
  • Methods and apparatus for enhanced cell detection
    Patent number: 9301233
    Abstract: Methods and apparatus of cell detection include determining whether communication between a user equipment and a serving cell satisfies a serving cell unsuitability condition. The methods and apparatus further include performing one or more autonomous search procedures based on whether the serving cell unsuitability condition has been satisfied. Moreover, the methods and apparatus include conducting cell reselection based on one or more results from the one or more autonomous search procedures, wherein the one or more results indicate at least one suitable cell for reselection.

  • Method and apparatus for regaining service by selecting a detected cell not included in a neighbor cell list (NCL)
    Patent number: 9253689
    Abstract: The present disclosure presents a method and apparatus for regaining service at a user equipment. For example, the disclosure presents a method for receiving a neighbor cell list from a serving cell, and scanning to identify target cells by the user equipment, wherein the target cells include neighbor cells included in the neighbor cell list and detected cells not included in the neighbor cell list. In addition, such an example method may include determining that the user equipment cannot successfully camp on any one of the neighbor cells, and attempting to camp on one of the detected cells. As such, an improved method and apparatus for regaining service at a user equipment may be achieved.
