Publication number: 20230319920Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured with two subscriptions. The first subscription may support dual connectivity with one or more cell groups, such as a master cell group (MCG) and a secondary cell group (SCG), while a second subscription may not support dual connectivity. Each subscription may support communications with one or more radio access technologies (RAT). The UE may use the protocol stack for a RAT in the first subscription to receive idle-mode signaling, such as one or more paging messages, from the second subscription using the same RAT.Type: ApplicationFiled: August 28, 2020Publication date: October 5, 2023Inventors: Ling XIE, Bhupesh Manoharlal UMATT, Reza SHAHIDI, Qingxin CHEN, Shan QING, Mutaz Zuhier Afif SHUKAIR, Tom CHIN, Hemanth Kumar RAYAPATI, Tongxin WANG, Daniel AMERGA, Peng HU, Xuqiang ZHANG, Xiaoyu LI, Liang HONG, Zhongsheng LI

Patent number: 11589406Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine whether a slot timing difference, between a first cell and a second cell for a dual connectivity mode, satisfies a threshold value, where the first cell is a serving cell associated with a first radio access technology (RAT) and the second cell is a serving cell or a candidate cell associated with a second RAT. The UE may perform an operation to prevent the dual connectivity mode with the second cell, establish the dual connectivity mode with the second cell, maintain the dual connectivity mode with the second cell, or terminate the dual connectivity mode with the second cell based at least in part on whether the slot timing difference satisfies the threshold value. Numerous other aspects are provided.Type: GrantFiled: November 24, 2020Date of Patent: February 21, 2023Assignee: QUALCOMM IncorporatedInventors: Harish Venkatachari, Arvind Vardarajan Santhanam, Sandeep Rao, Ashwin Alur Sreesha, Hemanth Kumar Rayapati

Patent number: 9294141Abstract: Methods and devices are disclosed for enabling improved performance for page decodes on a SIM of a multi-SIM wireless communication device in which a shared radio frequency (RF) resource is used to read system information for a different SIM. After determining that a first SIM is using the shared RF resource to decode SIBs, the wireless device may receive information about an upcoming page decode time for monitoring a paging channel associated with the second SIM. The wireless device may obtain system information block (SIB) scheduling information associated with the first SIM, and may create a RF resource release gap during the system information read period based on the SIB scheduling information and the upcoming page decode time. Control of the RF resource may be released from the modem stack associated within the first SIM, and gained by a modem stack associated with the second SIM during the RF resource release gap.Type: GrantFiled: October 2, 2014Date of Patent: March 22, 2016Assignee: QUALCOMM IncorporatedInventors: Nikhil Challa, Deepti Mani, Hemanth Kumar Rayapati, Rakesh Surapaneni, Suresh Sanka, Sathish Krishnamoorthy, Subbarayudu Mutya, Venkata Appala Naidu Babbadi
