Patent number: 11159592Abstract: Devices, systems and methods are provided to support a party call with auto-joining function in a communication system for a distributed transport system that employs VoIP technology. A VoIP unit or end point acts as a conference bridge between an operator extension and other end points. A first end point makes a SIP call to the operator and multicasts a mix of its send audio and the received operator audio. Other end points first check for multicast traffic being received before making a SIP call to the operator and, if so, play out the received audio over its speaker and multicast its send audio. The end point initiating the call mixes this subsequent stream into a stream to the operator, effectively acting as the conference bridge to the operator. The other end points are responsible for mixing received multicast streams for their local speaker.Type: GrantFiled: March 12, 2020Date of Patent: October 26, 2021Assignee: Hubbell IncorporatedInventor: Richard Crampton Rumsby

Patent number: 11160109Abstract: This disclosure provides methods, devices, systems, and computer programs encoded on storage media, for clear channel assessment (CCA) for a wide bandwidth channel. For example, a wide bandwidth channel may have a bandwidth that is greater than 160 MHz bandwidth. An example wide bandwidth channel has a 320 MHz bandwidth. The CCA techniques include detection thresholds that may be used for wide bandwidth channels. In some implementations, a CCA process may be extended to include assessments of extended portions of a wide bandwidth channel (such as a tertiary 80 MHz bandwidth channel and a quaternary 80 MHz bandwidth channel). In some implementations, a CCA process may be extended to use an assessment of a secondary channel of the wide bandwidth channel that has a 160 MHz bandwidth.Type: GrantFiled: November 6, 2019Date of Patent: October 26, 2021Assignee: QUALCOMM INCORPORATEDInventors: Lin Yang, Bin Tian
