Publication number: 20230328709Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive first configuration information indicating a transmission time interval (TTI) bundling resource. The UE may receive second configuration information indicating semi-persistent scheduling (SPS) resources. The UE may detect, during a communication session, an SPS trigger for using the SPS resources in a subframe that is misaligned with a periodicity associated with the TTI bundling resource. The UE may determine whether the SPS trigger is valid based at least in part on a number of TTI bundling grants subsequent to the detection of the SPS trigger that are misaligned with the subframe associated with the SPS trigger. Numerous other aspects are provided.Type: ApplicationFiled: September 21, 2021Publication date: October 12, 2023Inventors: Nan ZHANG, Ahmed Omar Desouky ALI, Sumanth Kumar KOTA, Neha JOTHI, Zhibin DANG

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

Patent number: 5388863Abstract: This invention is a method for joining sections of in-situ cement-mortar lined pipes adapted for high pressure water injection service. The method utilizes a backing ring with one beveled end inserted into a beveled end of the first pipe section and the other beveled end of the backing ring projecting from the first section and adapted to mate with a beveled end of the second pipe section. The pipe sections are then cement-mortar lined. The ends of the linings are then cut back and beveled to facilitate alignment and fit-up, and to provide a cavity and anchor for the retention of a heat expanding grout that is applied to both ends of the lined mating pipe sections to seal the joint. A root opening is left between the mated ends to permit weld penetration and fusion of the butted ends of the steel pipe and a space for the excess and expanding grout to protrude internally.Type: GrantFiled: July 20, 1993Date of Patent: February 14, 1995Assignee: Saudi Arabian Oil CompanyInventor: Ahmed A.
