Patent number: 10938520Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, at a first operational layer of the receiving device, one or more protocol data units (PDUs) within a set of PDUs. The receiving device may identify, at a second operational layer of the receiving device, a sequence gap associated with a missing PDU from the set of PDUs, the first operational layer being a lower operational layer of the receiving device than the second operational layer. The receiving device may determine, at the second operational layer, that a triggering condition associated with the missing PDU has occurred. The receiving device may provide, by the second operational layer and based at least in part on the triggering condition occurring, an indication to update a reception buffer of the first operational layer to a last received protocol data unit of the set of PDUs.Type: GrantFiled: May 22, 2019Date of Patent: March 2, 2021Assignee: QUALCOMM IncorporatedInventors: Arun Prasanth Balasubramanian, Shailesh Maheshwari, Xing Chen, Arnaud Meylan, Jason Tan, Wei-Jei Song

Patent number: 10805828Abstract: Methods, systems, and devices are described for wireless communication. A user equipment (UE), for example, may determine a content size of an uncompressed buffer and a content size of a compressed buffer. The UE may then generate a buffer status report (BSR) based on the content sizes of the uncompressed buffer and the compressed buffer. Alternatively, a base station may receive a BSR based on a size of an uncompressed buffer of the UE. The base station may then receive a compressed packet from the UE and may determine a compression gain based on a size of the compressed packet and a size of a corresponding uncompressed packet. The base station may then adjust the received BSR based on the compression gain.Type: GrantFiled: July 11, 2019Date of Patent: October 13, 2020Assignee: QUALCOMM IncorporatedInventors: Seyed Ali Ahmadzadeh, Srinivasan Balasubramanian, Shailesh Maheshwari, Ashwini Raina, Vishal Dalmiya, Rohit Kapoor, Leena Zacharias, Bao Vinh Nguyen

Patent number: 10805430Abstract: Methods, systems, and devices are described for wireless communication at a UE. In aspects, a receiver may receive a transmission requesting information about support for data compression. The receiver may determine parameters related to the types of supported data compression and communicate the information to the transmitting device. In some cases, the receiver may then receive a message from the transmitting entity that requests establishment of a data compression configuration. The receiver may respond with confirmation or rejection of the proposed compression configuration. If the configuration is confirmed, the transmitter and receiver may exchange compressed data packets according to the configuration. The devices may exchange status and control information related to the compression configuration (e.g., in a compression header of a compressed message or a separate status and/or control information message).Type: GrantFiled: April 12, 2019Date of Patent: October 13, 2020Assignee: QUALCOMM IncorporatedInventors: Ashwini Raina, Shailesh Maheshwari, Vishal Dalmiya, Srinivasan Balasubramanian, Rohit Kapoor, Seyed Ali Ahmadzadeh, Leena Zacharias

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
