Publication number: 20250113327Abstract: This disclosure is directed to systems and methods for interference mitigation in satellite communication. For satellite communication, an electronic device may perform a GNSS position fix prior to establishing satellite communication. In some cases, a GNSS downlink frequency band may be close to a satellite uplink frequency band, and as a result a first device communicatively connecting to a satellite downlink frequency band may interfere with one or more other devices in close proximity attempting to connect to the GNSS uplink frequency band, and consequently the first device may prevent the one or more other devices from performing the GNSS position fix. Because of this, one electronic device may block satellite communication for multiple other electronic devices. This may be particularly relevant in situations involving large crowds (e.g., festivals, sporting events), during calamity events, and/or in outdoor scenarios (e.g., group hikes).Type: ApplicationFiled: May 22, 2024Publication date: April 3, 2025Inventors: Dhruv Khati, Sanjeevi Balasubramanian, Anjaneyulu Maganti, Krishna Myneni, Venkateswara Rao Manepalli

Publication number: 20250063425Abstract: A cellular communications system may include a user equipment (UE) that executes a target and non-target applications. The UE may convey a first stream of non-quality-of-service (QoS) wireless data with a first external device over a first Transmission Control Protocol (TCP) session and may receive a second stream of non-QoS wireless data from a second external device over a second TCP session. Responsive to a drop in data rate of the first stream, the UE may perform mitigation operations that adjust receipt of the second stream to boost the data rate of the first stream. The mitigation operations may include transmission of a triple duplicate acknowledgement (TDA), delayed transmission of an acknowledgment (ACK) to the second stream, and/or terminating the second TCP session. This may prevent disruptions to user experience with the first software application even when the network has downlink data to transmit to the UE.Type: ApplicationFiled: July 12, 2024Publication date: February 20, 2025Inventors: Vishwanth Kamala Govindaraju, Sriram Subramanian, Alosious Pradeep Prabhakar, Vijendrakumar K Ashiwal, Vijay Venkataraman, Shiva Krishna Narra, Sanjeevi Balasubramanian

Publication number: 20240397501Abstract: This disclosure provides various techniques for decreasing the time it takes user equipment to tune away from a compromised network connection. By more quickly detecting a signal characteristic issue (e.g., signal quality issue) in the compromised signal and performing mitigation actions, the user equipment may decrease power consumption and increase data throughput. The signal quality issue may be detected by monitoring the location of the user equipment, a channel impulse response of the user equipment, and/or a block error rate (BLER) of a signal, among other methods. The data obtained may be fed into confidence validation logic, which may determine a level of confidence that the signal quality issue may cause a weak or broken connection between the user equipment and a network. The confidence validation logic may, based on the determination, operate the user equipment in an active state, a suspend state, or a release state.Type: ApplicationFiled: August 1, 2024Publication date: November 28, 2024Inventors: Sharad Sambhwani, Dirk Nickisch, Madhukar Krishnamoorthi Shanbhag, Sanjeevi Balasubramanian, Shiva Krishna Narra, Sriram Subramanian, Vishwanth Kamala Govindaraju
