Publication number: 20230217430Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify that uplink data is available for transmission at the UE prior to a scheduling request occasion. The UE may skip transmission of a scheduling request during the scheduling request occasion based on identifying that an uplink grant is pending. The UE may transmit at least a portion of the uplink data to a base station using a resource allocation indicated by the uplink grant. Alternatively, the UE may transmit the scheduling request to the base station during a first scheduling request occasion. The UE may initiate a retransmission timer based on transmitting the scheduling request. Accordingly, the UE may skip retransmission of the scheduling request during a second scheduling request occasion that is subsequent to the first scheduling request occasion based on the retransmission timer.Type: ApplicationFiled: January 4, 2022Publication date: July 6, 2023Inventors: Akshay Kumar, Arnaud Meylan, Avinash Manda, Zhibin Dang, Krishna Chaitanya Mukkera, Michel Chauvin

Patent number: 11671202Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may adaptively switch between hybrid automatic repeat request (HARQ) monitoring modes to support power savings. In a first HARQ skipping mode, the UE may transmit an uplink message corresponding to a HARQ identifier and may receive a positive acknowledgment (ACK) message in a HARQ monitoring occasion associated with the HARQ identifier. Upon receiving the ACK message, the UE refrains from monitoring a subsequent HARQ monitoring occasion associated with the HARQ identifier while in the first HARQ skipping mode (e.g., an aggressive HARQ skipping mode). The UE may periodically enter a periodic evaluation mode from the first HARQ skipping mode, in which the UE monitors a subsequent HARQ monitoring occasion after receiving an ACK message to check for false ACK messages. If a false ACK message is detected, the UE enters a first HARQ skipping prohibited mode.Type: GrantFiled: December 1, 2020Date of Patent: June 6, 2023Assignee: QUALCOMM IncorporatedInventors: Ahmed Omar Desouky Ali, Brian Clarke Banister, Supratik Bhattacharjee, Udayan Murli Bhawnani, Jittra Jootar, Timothy Paul Pals, Rebecca Wen-Ling Yuan, Arvind Vardarajan Santhanam, Zhibin Dang, Omesh Kumar Handa, Sibasish Das, Chetan Jagdeesh Bharadwaj, Gautham Hariharan, Min Wang, Farrukh Rashid, Nan Zhang, Sumanth Kumar Kota
