Patent number: 11476989Abstract: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.Type: GrantFiled: June 19, 2020Date of Patent: October 18, 2022Assignee: Futurewei Technologies, Inc.Inventors: Jialing Liu, Weimin Xiao, Murali Narasimha, Brian Classon, Qian Cheng

Patent number: 11470579Abstract: Embodiments herein describe using a dual assess point (AP) to establish two access points that both are established by two individual radios (e.g., two 5 GHz radios). Generally, APs experience highly degraded performance when two co-located radios operate within the same band. In one embodiment, AP devices can deploy same band radios using a macro-micro cell approach. Thus, the AP may intelligently hand off client devices between the micro and macro cell in a way that optimizes the system for overall throughput and low packet latency while creating minimal oscillation of clients between cells. The embodiments in this disclosure disclose techniques that direct clients in a manner that optimizes these factors.Type: GrantFiled: October 9, 2020Date of Patent: October 11, 2022Assignee: Cisco Technology, Inc.Inventors: Vishal Satyendra Desai, John Blosco, Allen Huotari

Patent number: 11463371Abstract: Methods, systems, and apparatuses for discovering dynamic path maximum transmission unit (PMTU) between a sending computing device and a receiving computing device (e.g., a client device and a host device) are described herein. A sending computing device may iteratively transmit bursts of probe packets, each burst being defined by a search range between a maximum packet size and a minimum packet size. The sending computing device may iteratively update the search range based on the previous iteration until the search converges on the PMTU. When the PMTU is discovered, each of the computing devices may update their transport and presentation layer buffers based on the discovered PMTU without any other protocol level disruption. In a multi-path scenario, the computing device may discover PMTU for each of the paths and select a performance optimal path based on the individual PMTUs and other network characteristics such as loss, latency, and throughput.Type: GrantFiled: June 2, 2020Date of Patent: October 4, 2022Assignee: Citrix Systems, Inc.Inventors: Georgy Momchilov, Rakesh Ranjan Jha, Jeffrey Holsapple, Sridharan Rajagopalan
