Publication number: 20240114456Abstract: Methods and apparatus for targeted wake-up and frame enhancement for energy harvesting are disclosed. In one embodiment, a method performed by a station (STA) may compromise: receiving, during an energy detection state, a zero energy (ZE) frame from an access point (AP) that indicates a presence of an energy harvesting (EH) window; harvesting energy for a determined time duration during the EH window; and receiving, during an information decoding state, a data portion of the ZE frame based on a current stored energy of the STA being above a first threshold and a signal strength of the received ZE frame being above a second threshold.Type: ApplicationFiled: February 8, 2022Publication date: April 4, 2024Applicant: INTERDIGITAL PATENT HOLDINGS, INC.Inventors: Nagi Mahalingam, Hussain Elkotby, Ravikumar Pragada, Tanbir Haque, Vikas Gulati

Patent number: 10595214Abstract: Methods, systems, apparatuses, and devices are described for managing wireless communication at a user equipment (UE). An exemplary method includes adding an identifier of a cell to a sub-optimal cell list based at least in part on a cell classification determination made by the UE, and avoiding a cell access procedure for the cell based at least in part on inclusion of the identifier in the sub-optimal cell list. Another exemplary method includes maintaining a sub-optimal cell list and an associated priority service exception list, initiating a service on the priority service exception list, identifying inclusion of a cell on the sub-optimal cell list, where the cell is associated with a cell access procedure initiated for the service, and accessing the cell included in the sub-optimal cell list based at least in part on inclusion of the service in the priority service exception list.Type: GrantFiled: July 15, 2016Date of Patent: March 17, 2020Assignee: QUALCOMM IncorporatedInventors: Arvind Santhanam, Francesco Grilli, Simon Walke, Venkata Potnuru, Vikas Gulati, Neha Goel

Patent number: 9887813Abstract: Information can transfer from a transmitter to a receiver; however, the transmission can consume valuable resources. Therefore, a number of times a transmission is attempted can be tracked and compared against a threshold value. If the transmission occurs too many times—based upon the comparison—then a reset can occur. Tracking can occur for a protocol data unit and/or a control protocol data unit to determine if a reset should occur.Type: GrantFiled: May 21, 2008Date of Patent: February 6, 2018Assignee: QUALCOMM IncorporatedInventors: Shailesh Maheshwari, Thomas Klingenbrunn, Tim T. Liou, Suresh Sharma Gannamaraju, Vikas Gulati, Sitaramanjaneyulu Kanamarlapudi

Publication number: 20170303181Abstract: Wireless communication at a user equipment (UE) is described. In some cases, a UE may determine that a voice call is about to be setup or in the process of being setup with a cell that supports voice calls. While the voice call is pending, the UE may be motivated to connect to a cell that does not support voice calls. The UE may recognize that the cell does not support voice calls and refrain from connecting to the cell until after the voice call setup, and/or the voice call itself, has completed.Type: ApplicationFiled: April 13, 2016Publication date: October 19, 2017Inventors: Vagish Gupta, Liangchi Hsu, Ansah Ahmed Sheik, Vikas Gulati

Patent number: 9686736Abstract: In various aspects, the disclosure provides user equipment (UE) capable of conducting a public land mobile network (PLMN) search by determining a paging schedule for a serving cell of the UE, the serving cell being associated with a first PLMN and the paging schedule defining one or more paging occasions. The UE may initiate a search for a second PLMN between consecutive paging occasions, and may read information blocks on a broadcast channel of a cell of the second PLMN. The UE may discontinue reading a partially-read information block when the partially-read information block is scheduled for transmission at least partially concurrently with a paging occasion on the serving cell if the partially-read information block does not include information for identifying the second PLMN. The UE may ignore the first paging occasion when the partially-read information block includes the information for identifying the second PLMN.Type: GrantFiled: July 3, 2014Date of Patent: June 20, 2017Assignee: QUALCOMM IncorporatedInventors: Chaitanya Baratam, Sivasubramanian Ramalingam, Vikas Gulati, Girish Valluru, Sathish Krishnamoorthy, Satish Pavan Kumar Nichanametla

Publication number: 20160242072Abstract: Methods, systems, and devices are described for handling over-sized call setup messages are disclosed. A user equipment (UE) may identify the size of a connection setup message (e.g., RRC connection setup complete message) associated with one or more UE capability information. Based on the identified size of the connection setup message, the UE may determine an estimated time required to transmit the connection setup message to a network entity (e.g., base station) over at least one uplink channel and determine whether the estimated time is above or below a threshold. If the UE determines that the estimated time to transmit the connection setup message is greater than the threshold, the UE may remove at least a portion of the connection setup message and transmit a modified connection setup message.Type: ApplicationFiled: August 20, 2015Publication date: August 18, 2016Inventors: Liangchi Hsu, Sitaramanjaneyulu Kanamarlapudi, Sivasubramanian Ramalingam, Yongsheng Shi, Vikas Gulati, Sathish Krishnamoorthy

Patent number: 9185610Abstract: A method and apparatus for wireless communications are provided. A first cell on which a user equipment (UE) is camped may be identified as a visited Public Land Mobile Network (VPLMN) of the UE. Information of a second cell among neighboring cells of the first cell may be received via a broadcast message from the first cell. The second cell may be part of a home PLMN (HPLMN) and the HPLMN may not be an equivalent PLMN (EPLMN) to the VPLMN associated with the first cell. Alternatively, the second cell may belong to an Equivalent HPLMN (EPLMN). When the second cell is determined to be a best cell according to absolute priority reselection rules or a highest ranked cell among the neighboring cells of the first cell, the second cell may not be barred for a period of time from being considered or identified as a candidate for reselection.Type: GrantFiled: June 24, 2014Date of Patent: November 10, 2015Assignee: QUALCOMM IncorporatedInventors: Vikas Gulati, Girish Valluru, Yongsheng Shi, Liangchi Hsu

Publication number: 20140376393Abstract: Aspects of the disclosure provide apparatus and methods of inter-system measurements operable at a user equipment (UE) in a wireless communication network. The UE establishes a connection with a network node in a first wireless communication network utilizing a first radio access technology (RAT), wherein the UE is capable of measuring a plurality of frequency bands of a second RAT greater in number than a measurement capability report limit of the first RAT. The UE further selects a subset of the plurality of frequency bands of the second RAT to be included in a measurement capability information element (IE) based on information provided by the network node and information stored at the UE. The UE further transmits the measurement capability IE to the network node.Type: ApplicationFiled: November 18, 2013Publication date: December 25, 2014Applicant: QUALCOMM IncorporatedInventors: Yongsheng Shi, Sathish Krishnamoorthy, Vikas Gulati, Satish Pavan Kumar Nichanametla, Liangchi Hsu
