Patent number: 11252597Abstract: Aspects of the present disclosure describe transmitting data in wireless communications. A set of packets for transmission in a defined sequence can be received where the set of packets includes two or more packets. It can be detected that a packet, of the set of packets, is a prioritized packet type. The packet can be prioritized for transmission ahead of its order in the defined sequence based on the detection of the prioritized packet type. The packet can be transmitted ahead of its order in the defined sequence to an access point.Type: GrantFiled: October 25, 2019Date of Patent: February 15, 2022Assignee: QUALCOMM INCORPORATEDInventors: Arnaud Meylan, Gavin Bernard Horn, Yu-Ting Yu, Aziz Gholmieh, Yue Yang, Shailesh Maheshwari, Sitaramanjaneyulu Kanamarlapudi, Vaibhav Kumar, Sivaramakrishna Veerepalli, Srinivasan Balasubramanian, Srinivas Reddy Mudireddy, Vanitha Kumar

Patent number: 10757754Abstract: Techniques are described herein to secure a packet data convergence protocol (PDCP) control protocol data unit (PDU). A base station may determine a security configuration for a PDCP control PDU based on various factors including the content of the PDCP control PDU. For example, the security configuration of the PDCP control PDU may be applied because the PDCP control PDU includes a retransmission request. A counter dedicated to PDCP control PDUs may be initialized. The security protocols may be based on the dedicated counter. Some types of security parameters may be shared in some contexts such as in handover procedures or dual connectivity procedures. For example, security configurations associated with a second communication link may be based on security configurations associated with a first communication link. PDCP control PDUs may be secured based on the security configurations, the security parameters, protection keys, or combinations thereof.Type: GrantFiled: May 15, 2017Date of Patent: August 25, 2020Assignee: QUALCOMM IncorporatedInventors: Soo Bum Lee, Gavin Bernard Horn, Yu-Ting Yu, Shailesh Maheshwari, Vanitha Kumar

Patent number: 9094202Abstract: Systems and methodologies are described that facilitate utilizing hybrid automatic repeat/request (HARQ) in system access communications. A HARQ entity is provided that manages a plurality of HARQ processes, which can typically use new data indicators (NDI) to determine when received data is a new transmission or retransmission. For resource grants, the HARQ entity can determine whether the communication is a new transmission or retransmission based on the type of message that contains the grant. In addition, an address comprised within the message, a previous use of the HARQ process, and/or the like can further be utilized to determine whether the message is a new transmission or retransmission. Once determined, the HARQ entity can provide the message to the appropriate HARQ process along with the indication of new transmission or retransmission.Type: GrantFiled: July 10, 2009Date of Patent: July 28, 2015Assignee: QUALCOMM IncorporatedInventors: Shailesh Maheshwari, Srividhya Krishnamoorthy, Vanitha A.

Patent number: 8873522Abstract: In a wireless communication system, user equipment (UE) is provided, one or more set of rules are provided for the UE to handle the processing during a measurement gap. In some aspects, the gap measurement may be ignored. In some aspects, the processing is stored and handled at a later in time and gap measurements are performed. Depending on the system, the measurements performed during the gaps may be UE implementation dependent, wherein the UE determines whether to perform the measurement for a given gap. In some instances, the UE may not perform measurements during the gap, thereby giving priority to other processing, such as RACH processing. Depending on the type of processing required (DL-SCH, UL-SCH, TTI bundling, RACH or SR), the UE may store requests and process the measurements during the gap or ignore the gap measurement as if there were no gaps.Type: GrantFiled: July 10, 2009Date of Patent: October 28, 2014Assignee: QUALCOMM IncorporatedInventors: Arnaud Meylan, Srividhya Krishnamoorthy, Shailesh Maheshwari, Vanitha A.

Patent number: 8594031Abstract: Methods and apparatuses are provided that facilitate providing quality of service for similar priority logical channels at least in part by assigning dynamic priority levels to the logical channels to allow certain logical channels to be assigned resources before other logical channels. Dynamic priority levels can be assigned based at least in part on a total accumulated used bytes of a given logical channel scaled by a prioritized bit rate of the logical channel. Thus, logical channels with a lower number of total accumulated used bytes scaled by the prioritized bit rate can be assigned higher priority to ensure resources are assigned to the logical channels. Moreover, the dynamic priority levels can be normalized to align the dynamic priority levels within certain values so as not to interfere with other logical channels of different assigned priority.Type: GrantFiled: October 1, 2010Date of Patent: November 26, 2013Assignee: QUALCOMM IncorporatedInventors: Bao V. Nguyen, Srividhya Krishnamoorthy, Vanitha A. Kumar, Sai Yiu Duncan Ho

Patent number: 8489092Abstract: Systems and methodologies are described that facilitate collecting consistent system information when entering a cell during cell selection and/or cell re-selection in a wireless communication environment. SIB(s) can be received while lacking modification period information (e.g., modification period boundary, modification period duration, . . . ). Further, the SIB(s) can be stored in memory with corresponding SFN(s) at which the SIB(s) are respectively received. Thereafter, the modification period information can be identified (e.g., from a SIB2, . . . ). Moreover, an evaluation can be effectuated to determine whether to retain or discard the SIB(s) from memory as a function of the modification period information and the corresponding SFN(s). Further, whether to retain or discard the SIB(s) from memory can be based upon a value tag.Type: GrantFiled: May 4, 2010Date of Patent: July 16, 2013Assignee: Qualcomm IncorporatedInventors: Amit Mahajan, Vanitha A.
