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: 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: 10470090Abstract: A user equipment (UE) and source base station may use data compression techniques for data packets sent between them. During a handover, the source base station may provide data compression context to a target base station, thus enabling the target base station to continue the data compression following the handover without having to reestablish the data compression context. The source base station may determine data compression capabilities of the UE or the target base station, or both, and may communicate the determined data compression capabilities to the UE or target base station. The source base station may identify at least one gap in a sequence of packets received from the UE, and communicate the existence of the gap to the target base station, which may request retransmission of packets associated with the gap.Type: GrantFiled: November 12, 2015Date of Patent: November 5, 2019Assignee: QUALCOMM IncorporatedInventors: Srinivasan Balasubramanian, Seyed Ali Ahmadzadeh, Shailesh Maheshwari, Ashwini Raina, Rohit Kapoor, Leena Zacharias, Vishal Dalmiya
