Publication number: 20240056976Abstract: Certain aspects of the present disclosure provide a method for wireless communication by a user equipment (UE). The UE starts a first timer (such as a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round-trip-time (RTT) timer), after sending an uplink (UL) data transmission to a network entity. The UE then starts a second timer (such as a DRX retransmission timer) when the first timer expires. The UE then determines whether to wake up or sleep for a duration of the second timer based on a prior block error rate (BLER).Type: ApplicationFiled: October 10, 2023Publication date: February 15, 2024Inventors: Leena ZACHARIAS, Arnaud MEYLAN, Reza SHAHIDI, Lan LAN, Qingxin CHEN, Farrukh RASHID, Zhibin DANG, Akshay KUMAR

Patent number: 11895593Abstract: To reduce power consumption, a user equipment (UE) may trigger a microsleep in a subframe when a physical downlink control channel (PDCCH) does not include a downlink grant. However, because the microsleep depends on the PDCCH not including a downlink grant, the UE cannot trigger the microsleep until after the PDCCH is decoded. Accordingly, in some aspects, a UE may enable an aggressive extra microsleep in which a microsleep duration may be increased by reducing a PDCCH decode time. For example, a UE may use a stale channel estimate and noise estimate from a previous subframe to perform PDCCH demapping when conditions related to a PDCCH block error rate are satisfied. In this way, removing channel estimation and noise estimation from a PDCCH demapping path may reduce the PDCCH decode time, whereby the UE may trigger a microsleep sooner to increase a sleep ratio and thereby increase power savings.Type: GrantFiled: March 8, 2022Date of Patent: February 6, 2024Assignee: QUALCOMM IncorporatedInventors: Manu Krishnan Kavunkal, Manav Lnu, Manish Jain, Abhishek Kumar, Venkata Pavan Kumar Bhargav Medepally, Kiran Singh Matharu, Parees Kambli, Awlok Singh Josan, Farrukh Rashid, Ashutosh Vinod Agrawal

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: 11503620Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify, based at least in part a determination to transmit one or more packets, a scheduling request (SR) occasion in which to transmit an SR for uplink resources to transmit the one or more packets, the SR occasion occurring prior to a start of a connected discontinuous reception (CDRX) on duration of the UE. The UE may determine whether the SR occasion occurs within a threshold amount of time prior to the start of the CDRX on duration of the UE. The UE may transmit the SR in the SR occasion based at least in part on the determination of whether the SR occasion occurs within the threshold amount of time prior to the start of the CDRX on duration of the UE. Numerous other aspects are provided.Type: GrantFiled: August 25, 2020Date of Patent: November 15, 2022Assignee: QUALCOMM IncorporatedInventors: Farrukh Rashid, Min Wang, Omesh Kumar Handa, Rajarajan Rajendran

Patent number: 11452043Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may identify a wake up time period corresponding to a wake up cycle, transmit a message that includes an identifier of the UE within a first resource pool during a first portion of the wake up time period based on the wake up cycle, and monitor for a paging signal from a vehicle UE during a paging occasion of the wake up time period based on transmitting the message. A vehicle UE may identify a wake up configuration for a wake up time period, receive, within a first portion of the wake up time period, a message within a resource pool that includes the identifier of the UE. The vehicle UE may transmit a paging signal within a paging occasion of the wake up time period.Type: GrantFiled: June 15, 2020Date of Patent: September 20, 2022Assignee: QUALCOMM IncorporatedInventors: Anantharaman Balasubramanian, Sudhir Kumar Baghel, Shailesh Patil, James Francis Geekie, Farrukh Rashid, Cheol Hee Park

Publication number: 20150319743Abstract: Fast Associated Control Channel (FACCH) information is combined if a first block of FACCH information and a repeated block of FACCH information each fail a respective integrity check. An algorithm for realizing repeated FACCH diversity combining gains for different codec and discontinuous transmission (DTX) configurations is applicable to Full Rate codecs, Half Rate codecs, and discontinuous transmission scenarios. A pair of buffers may be used in a ping-pong fashion to store decoding soft or hard decisions for failed FACCH blocks.Type: ApplicationFiled: October 27, 2014Publication date: November 5, 2015Inventors: Farrukh Rashid, Divaydeep Sikri, Mukund Agarwal, Hassan Rafique, Cetin Altan

Patent number: 9030927Abstract: Access terminals are adapted to blacklist one or more neighboring cells from acquisition attempts. For instance, an access terminal may receive a transmission including a list of neighboring cells to be monitored while connected to a particular serving cell. The access terminal may determine that a predefined number of consecutive acquisition attempts with a particular neighboring cell have failed. In response to failure of the predefined number of consecutive acquisition attempts, the access terminal can blacklist the neighboring cell from subsequent acquisition attempts for a predefined blacklisting period. Following the duration of the blacklisting period, the access terminal may conduct a subsequent acquisition attempt with the neighboring cell. Other aspects, embodiments, and features are also claimed and described.Type: GrantFiled: August 19, 2014Date of Patent: May 12, 2015Assignee: QUALCOMM IncorporatedInventors: Jafar Mohseni, Divaydeep Sikri, Farrukh Rashid

Patent number: 8964617Abstract: Access terminals are adapted to regulate power in wireless receiver circuits. In one example, access terminals include a communications interface with at least one wireless receiver circuit. A processing circuit coupled with the communications interface can receive a transmission during a Frequency Correction Channel (FCCH) frame. Following the received transmission, at least a portion of the receiver circuit may be powered down. A determination may also be made whether the received transmission was reliable. The receiver circuit can subsequently be powered up, and another transmission can be received on a subsequent channel. When the received transmission was sufficiently reliable, the other transmission may be a transmission during a Synchronization Channel (SCH) frame. When the received transmission is not sufficiently reliable, the other transmission may be another transmission received during a subsequent Frequency Correction Channel (FCCH) frame.Type: GrantFiled: January 11, 2013Date of Patent: February 24, 2015Assignee: QUALCOMM IncorporatedInventors: Divaydeep Sikri, Farrukh Rashid, Helena Deirdre O'Shea, Cetin Altan, Wolfram Pieperhoff
