Patent number: 11974291Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may activate or release one or more semi-persistent scheduling (SPS) configurations for group-common downlink shared channels based on signaling from a base station. For example, the UE may receive downlink control information (DCI) from the base station that includes a feedback process field, where a value of the feedback process field indicates at least one of one or more SPS configurations is to be activated. In some examples, the base station may transmit the DCI in a group-common downlink control channel or in a UE-specific downlink control channel. Additionally, the base station may transmit a deactivation message to the UE to indicate for the UE to release one or more activated SPS configurations, where the deactivation message is transmitted in a group-common downlink control channel or a UE-specific downlink control channel.Type: GrantFiled: April 1, 2021Date of Patent: April 30, 2024Assignee: QUALCOMM IncorporatedInventors: Le Liu, Kazuki Takeda, Alberto Rico Alvarino, Wanshi Chen

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

Patent number: 11936564Abstract: Techniques for a TCP proxy to communicate over a LEO satellite network on behalf of a client device by selecting a TCP congestion-control algorithm that is optimal for the LEO satellite network based on the time of day and/or location of the TCP proxy. Based on the locations of satellites during the day as they traverse predefined and patterned orbital paths, different TCP congestion-control algorithms may be more optimized to communicate data through the LEO satellite network. However, client devices generally use a single TCP congestion-control algorithm to communicate over WAN networks. Accordingly, a TCP proxy may be inserted on, for example, a router to communicate with the client device using a TCP congestion-control algorithm that the client device is configured to use, but then communicate over the LEO satellite network using a different TCP congestion-control algorithm that is optimal based on the time of day and/or other factors.Type: GrantFiled: May 18, 2022Date of Patent: March 19, 2024Assignee: CISCO TECHNOLOGY, INC.Inventors: David John Zacks, Jeff Apcar, Oliver Boehmer, Thomas Szigeti
