Patent number: 11968674Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a control message indicating a resource configuration for uplink and downlink transmissions. The UE may determine an uplink buffer threshold for a modem buffer of the UE based on the resource configuration. The UE may transmit, to the base station, a feedback request message requesting that the base station provide feedback for at least one previously transmitted uplink packet based on a comparison of an amount of previously transmitted uplink data and scheduled uplink data stored in the modem buffer relative to the uplink buffer threshold. The UE may receive, based on transmitting the feedback request message, a feedback response message corresponding to a first previously transmitted uplink packet of the at least one previously transmitted uplink packet.Type: GrantFiled: February 4, 2021Date of Patent: April 23, 2024Assignee: QUALCOMM IncorporatedInventors: Arnaud Meylan, Sitaramanjaneyulu Kanamarlapudi, Vishal Dalmiya, Kuo-Chun Lee, Shailesh Maheshwari, Vaishakh Rao, Arun Prasanth Balasubramanian, Subashini Krishnamurthy, Leena Zacharias, Sivashankar Sekar, Saket Bathwal, Liangchi Hsu, Raghuveer Ramakrishna Srinivas Tarimala

Publication number: 20230319668Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE), such as a dual-subscription UE, support a first subscription and a second subscription. The first subscription may be in an active mode with a first cell and the second subscription may be in an idle mode with a second cell, and the UE may determine whether to exit or postpone entrance into a merged state in which the UE may perform idle mode measurements for the second subscription using the first subscription and the first cell based on a channel quality-based merge condition. For example, the UE may measure a channel quality associated with a communication link between the UE and the first cell and, in examples in which the measured channel quality fails to satisfy a threshold channel quality, the UE may exit or postpone entrance into the merged state.Type: ApplicationFiled: October 14, 2021Publication date: October 5, 2023Inventors: Ling Xie, Rishika Tindola, Subashini Krishnamurthy, Uttam Vyas, Tom Chin, Daowei LIN
