Patent number: 11910326Abstract: During an uplink TDD slot, an UL UE transmits an UL signal that occupies a slot frequency range. Similarly, during a DL TDD slot, a DL UE receives a DL signal that occupies the slot frequency range. But during an SBFD slot, a UL UE transmits a UL signal that occupies only a first sub-band of the slot frequency range. Similarly, a DL UE receives a DL signal during an SBFD slot that occupies only a second sub-band of the slot frequency range. The second sub-band is distinct from the first sub-band. The DL UE may thus mitigate UE-to-UE interference during an SBFD slot by filtering the DL signal to substantially block the second sub-band from being received at the DL UE.Type: GrantFiled: October 31, 2020Date of Patent: February 20, 2024Assignee: QUALCOMM IncorporatedInventors: Joseph Patrick Burke, Muhammad Sayed Khairy Abdelghaffar, Charline Hao, Joseph Binamira Soriaga, Lai Kan Leung, Gurkanwal Singh Sahota, Tingfang Ji, Krishna Kiran Mukkavilli, Allen Minh-Triet Tran

Patent number: 9825767Abstract: Power management techniques for a network device providing services to other network devices. In one embodiment, a first device communicates requests for access to and release of a resource (such as a media serving service) hosted by a second device. Power management functionality in the second device selectively controls power to the resource based, at least in part, on such requests. For example, a resource may be placed in an inactive state following receipt of a request for release of the resource. Access to the resource may be provided through a network interface that is separately activated or deactivated by the power management functionality. In further embodiments, information relating to the state of the resource and/or network interface is provided by a proxy device.Type: GrantFiled: October 25, 2012Date of Patent: November 21, 2017Assignee: AVAGO TECHNOLOGIES GENERAL IP (SINGAPORE) PTE. LTDInventor: Stephen Ray Palm

Patent number: 9729936Abstract: Particular embodiments identify customer premise equipment (CPE) in a subscriber's premises that may potentially cause interference with other devices. For example, the interference may occur within an interfering spectrum where an interfering CPE transmits upstream in a frequency band that is the downstream frequency band for other customer premise equipment, such as legacy CPEs. Once the CPE is identified, when the CPE sends a request to initialize the CPE on the network, a cable modem termination service (CMTS) may adjust the target power level for a transmitter transmitting upstream content within the interfering frequency spectrum. For example, for those CPEs that transmit upstream using upstream channels within an interfering spectrum, such as within 54-85 MHz, the power level for these CPE may be reduced. Other CPEs that are not transmitting upstream in this interfering spectrum may not have their power reduced.Type: GrantFiled: November 16, 2015Date of Patent: August 8, 2017Assignee: ARRIS Enterprises LLCInventor: Jeffrey Joseph Howe

Patent number: 9461760Abstract: A method for remediating broadcast digital television signals is disclosed. A television signal is buffered by a multimedia client, and analyzed for errors. If errors are detected, replacement data for the corrupted data are requested from a service provider using a network back-channel. The replacement data are obtained from the broadcasting entity and sent back to the multimedia client. The replacement data are used to generate and display a faultless version of the digital television signal.Type: GrantFiled: October 29, 2008Date of Patent: October 4, 2016Assignee: AT&T Intellectual Property I, L.P.Inventors: Marc Sullivan, Steven M. Belz, James Pratt

Patent number: 9043855Abstract: A coupling device for use in a hybrid fiber coaxial (HFC) network may be configured to disable an upstream path through it when there is only noise incident on the upstream path, and enable the upstream path through it when a desired transmission from a cable modem downstream of the coupling device is incident on the upstream path. The coupling device may be a trunk amplifier, a distribution amplifier, a splitter, or the like. The coupling device may comprise a single upstream interface coupled to a plurality of downstream interfaces. The enabling and/or disabling may be in response to a signal strength indicated by the SSI being below a threshold and/or in response to one or more control messages indicating whether any downstream cable modem is, or will be, transmitting.Type: GrantFiled: July 23, 2013Date of Patent: May 26, 2015Assignee: MaxLinear, Inc.Inventors: Curtis Ling, Sridhar Ramesh, Timothy Gallagher

Publication number: 20150067756Abstract: A network tap can include a home network filter that is operable to prevent signals at predetermined frequencies from passing from a customer premise onto a service feed servicing the customer premise. In embodiments, one or more MoCA filters can be embedded within a cable tap, each MoCA filter being placed between an interface to a customer premise and a service feed servicing the customer premise. A MoCA filter embedded within a cable tap can block MoCA signals from passing onto a service feed and can reflect MoCA signals back into a customer premise.Type: ApplicationFiled: September 4, 2014Publication date: March 5, 2015Inventor: Stephen J.

Publication number: 20150067755Abstract: Techniques for adding WiFi capabilities to a region may include installing WiFi access points in a cable television (CATV) system. For easier installation of the WiFi access points, a WiFi access point extension devices may be integrated into existing taps in the CATV system. The WiFi extended taps are able to provide radio frequency (RF)/CATV signals to subscribers, provide power to the respectively integrated WiFi access point, and maintain power to the coaxial transmission line during installation. During installation, the WiFi access point extension devices can be integrated into the CATV outdoor distribution plant without having to splice into an existing coaxial transmission line. The multiplicity of existing tap locations in CATV distribution plants makes the positioning of new wireless access points extremely versatile for the cable provider.Type: ApplicationFiled: September 4, 2013Publication date: March 5, 2015Applicant: ARRIS Enterprises, Inc.Inventors: Dennis P.
