Patent number: 11979912Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may use easily detectable transmission parameters to infer difficult-to-detect parameters for communications with a base station. For example, the base station may provide the UE with multiple sets of transmission parameters, and the UE 115 may choose from among these sets of transmission parameters for the communications. In some cases, the UE may be configured with a reference set of transmission parameters, receive one or more transmission parameters that are different relative to the reference set of transmission parameters, and then determine to use the different transmission parameters for the communications. Additionally or alternatively, the multiple sets of transmission parameters may be specified for a certain uplink message (e.g., random access channel messages), where the UE selects the transmission parameter set based on one or more characteristics of the uplink message.Type: GrantFiled: February 5, 2020Date of Patent: May 7, 2024Assignee: QUALCOMM IncorporatedInventors: Gabi Sarkis, Jing Lei, Alexandros Manolakos, Alberto Rico Alvarino, Chih-Ping Li, Seyedkianoush Hosseini

Patent number: 11811671Abstract: Methods, systems, and devices for wireless communication are described to support entering a fast-negative acknowledgement (NACK) mode. A user equipment (UE) may enter a fast-NACK mode and may decrease a value of a respective timer for one or more wireless connections (e.g., may override the timer independently for each connection). The timer may be referred to as a retransmission request time duration. If configured with two or more component carriers (CCs), the UE may determine a value of the timer based on a location of a data hole within the two or more CCs. Based on entering the fast-NACK mode, the UE may override a configured timer for the respective wireless connection with a new, shorter timer. Based on expiration of the new timer, the UE may transmit an RLC NACK to a base station via the corresponding wireless connection.Type: GrantFiled: July 2, 2021Date of Patent: November 7, 2023Assignee: QUALCOMM IncorporatedInventors: Akshay Kumar, Arnaud Meylan, Shailesh Maheshwari, Arun Prasanth Balasubramanian, Utpal Barman
