Patent number: 10178561Abstract: Examples described herein relate to enhancing data communication performance in a wireless communication network including a first subscription associated with a first radio access technology (RAT) and a second subscription associated with a second RAT, where the wireless communication device uses a same radio frequency (RF) resource to communicate over both the first RAT and the second RAT. The first RAT is used, in part, for data operations while the second RAT is used, in part, for voice operations. During idle state voice operations, the RF resource is reallocated from performing data operations to performing idle state voice operations, causing interruptions in the data operations. The wireless communication device adjusts at least one or a duration and an occurrence of the idle state voice operations to reduce the impact on the data operations.Type: GrantFiled: February 24, 2017Date of Patent: January 8, 2019Assignee: QUALCOMM IncorporationInventors: Jun Hu, Qingxin Chen, Reza Shahidi, Yongsheng Shi, Jafar Mohseni, Yongle Wu, Yong Li, Shashank Maiya, Harish Venkatachari, Shriram Swaminathan, Scott Hoover, Sumit Kumar Singh, Kiran Patil, Zhong Fan, Uzma Khan Qazi, Sundaresan Tambaram Kailasam, Sunil Kumar Gurram

Patent number: 9749946Abstract: The present disclosure presents a method and apparatus for improved reselection during mode transitions at a user equipment (UE). For example, the disclosure presents a method for identifying that a user equipment (UE) has started switching from a first priority scheduling mode to a second priority scheduling mode while making measurements for reselection. In addition, such an example method, may include initiating a mode transition timer in response to the identification and triggering a search for one or more frequencies of the second priority scheduling mode upon expiration of the mode transition timer. As such, an improved reselection during mode transitions at UE may be achieved.Type: GrantFiled: October 8, 2013Date of Patent: August 29, 2017Assignee: Qualcomm IncorporatedInventors: Fan Wang, Sundaresan Tambaram Kailasam, An-Swol Clement Hu, Uzma Khan Qazi
