Publication number: 20240137814Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a customer premises equipment (CPE) may include or otherwise be in communication with a cellular modem and a wireless local area network (WLAN) access point (AP). The CPE may receive a first indication of a bandwidth part (BWP) configuration identifying an active BWP for the wireless communication. The CPE may send a second indication to switch to the active BWP for the wireless communication based on the BWP configuration. The CPE may communicate with stations (STAs) served by the CPE based on the active BWP. Additionally or alternatively, when the CPE detects a need for additional bandwidth, the CPE can request for additional bandwidth parts (e.g., BWPs).Type: ApplicationFiled: March 14, 2022Publication date: April 25, 2024Inventors: Syam Krishna Babbellapati, Sitaramanjaneyulu Kanamarlapudi

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

Patent number: 11963214Abstract: Aspects are provided which allow a UE to trigger initiation of an SR procedure in response to a decrease in an amount of received data or uplink grants following a measurement gap. The UE receives data from a first base station. The UE performs a measurement of a downlink signal from a second base station based on a measurement configuration. The UE transmits a scheduling request in response to a decrease in at least one of an amount of received downlink data or a number of received grants to transmit uplink data after the measurement is performed. As a result, inefficient data stalls caused by erroneous DRX determinations by a base station may be avoided.Type: GrantFiled: October 20, 2021Date of Patent: April 16, 2024Assignee: QUALCOMM IncorporatedInventors: Sitaramanjaneyulu Kanamarlapudi, Sathyanarayanan Raghunathan, Baojun Lu, Sivaram Srivenkata Palakodety

Publication number: 20240089962Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a user equipment (UE) to adaptively transition between modes of an adaptive receive diversity (ARD) antenna management configuration. In some cases, the UE may determine to transition from an ARD disallowed mode to an ARD standby mode in response to receiving a burst of downlink grants. The UE may dynamically update one or more criterion for transitioning between the ARD disallowed mode and the ARD standby mode according to a pattern of received downlink grants. For example, the UE may adjust a threshold quantity of downlink grants which constitutes a burst based on a downlink scheduling rate (DSR) of one or more prior ARD standby durations. In some cases, the UE may identify a fallback condition to transition from the ARD standby mode to the ARD disallowed mode.Type: ApplicationFiled: September 13, 2022Publication date: March 14, 2024Inventors: Touseef Khan, Sitaramanjaneyulu Kanamarlapudi, Varun Nuggehalli Ashok, Krishna Dilipbhai Patel, Ganesh Revanth Balasubramani

Publication number: 20240056225Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive control information that identifies criteria to use for determining a delivery status of a protocol data unit (PDU) set that includes multiple PDUs. The PDU set may be associated with an application layer of the UE. Accordingly, the UE may receive at least a portion of the PDU set, and may determine the delivery status of the PDU set based on the received portion of the PDU set and the criteria identified by the control information. The delivery status of the PDU set may refer to whether the PDU set was successfully delivered to the UE. The delivery status of the PDU set may be based on a quantity of bits or PDUs in the received portion of the PDU set, a threshold quantity of bits or PDUs, or a combination thereof.Type: ApplicationFiled: August 9, 2022Publication date: February 15, 2024Inventors: Mickael Mondet, Yih-Hao Lin, Prashanth Haridas Hande, Ravi Agarwal, Peerapol Tinnakornsrisuphap, Miguel Griot, Dario Serafino Tonesi, Sitaramanjaneyulu Kanamarlapudi, Ozcan Ozturk, Aziz Gholmieh, Sanket Sanjay Kalamkar, Gavin Bernard Horn, Linhai He

Publication number: 20240048286Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) determine that at least one packet of a set of packets for a downlink message is unsuccessfully received at a radio link control (RLC) layer of the UE due to a specific situation of a set of specific situations and may transmit the NACK message based on the missing packet (s) on an as needed basis rather than waiting for a timer to expire (e.g., a fast NACK mechanism). In some examples, the specific situations may include the UE missing packets after a measurement gap, missing packets based on wake up latencies for a discontinuous reception mode of the UE, missing packets due to interference from reference signals transmitted by neighboring cells, missing packets due to the UE not decoding retransmissions that have a same redundancy version (RV) of a downlink message, or a combination thereof.Type: ApplicationFiled: February 11, 2021Publication date: February 8, 2024Inventors: Sitaramanjaneyulu KANAMARLAPUDI, Ling XIE, Hobin KIM, Leena ZACHARIAS, Wei LI

Patent number: 11876635Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may selectively determine to decode a downlink shared channel multicast transmission based on whether the downlink shared channel includes a retransmission of an initial multicast transmission. A base station may transmit a message in a downlink control channel to indicate if the downlink shared channel is carrying the retransmission of the initial multicast transmission. For example, the base station may transmit a group random network temporary identifier, downlink control information with a retransmission indicator bit, or both to indicate if the downlink shared channel is carrying the retransmission. In some cases, the message in the downlink control channel may be received at a layer one (L1) of the UE, and the downlink shared channel transmission may be decoded at L1 of the UE and sent to a layer two (L2) of the UE for processing.Type: GrantFiled: December 10, 2020Date of Patent: January 16, 2024Assignee: QUALCOMM IncorporatedInventors: Prasad Reddy Kadiri, Sitaramanjaneyulu Kanamarlapudi, Le Liu, Kazuki Takeda, Gavin Bernard Horn, Xipeng Zhu, Umesh Phuyal, Alberto Rico Alvarino
