Patent number: 9692540Abstract: A system that incorporates the subject disclosure may include, for example, determining an interference based on a channel gain for each signal of a group of signals received at a receiver from a group of transmitters. A determination is made as to whether the interference satisfies a threshold range of an analog-to-digital converter of the receiver for each of the group of transmitters. An analog time domain cancellation is performed responsive to a determination that the interference does not satisfy the threshold range, and a digital time domain cancellation is performed responsive to a determination that the interference satisfies the threshold range. Other embodiments are disclosed.Type: GrantFiled: August 17, 2016Date of Patent: June 27, 2017Assignee: AT&T Intellectual Property I, L.P.Inventors: Vaneet Aggarwal, Dinesh Bharadia, Rittwik Jana, Christopher W.

Publication number: 20170134151Abstract: A system, method, and computer-readable storage media for reducing monopolization of a frequency channel during full-duplex communications. The MAC layer of governing communications can be modified to reduce likelihood of monopolization by (1) in networks which are exclusively filled with full-duplex devices, configuring non-communicating devices to ignore data collisions of communicating devices, requiring the communicating devices to wait for an standard backoff time after the data transmission is complete; and/or (2) in mixed half-duplex/full-duplex networks, requiring a half-duplex nodes and/or a full-duplex node to wait an extended duration after the data transmission is complete, while the non-communicating devices do not wait an extended duration.Type: ApplicationFiled: January 19, 2017Publication date: May 11, 2017Inventors: Vaneet AGGARWAL, Rittwik JANA, Christopher W.

Patent number: 9648612Abstract: A method, computer-readable storage device, and apparatus for allocating a plurality of timeslots of each channel of a plurality of channels in a wireless network are disclosed. For example, the method determines a location and a velocity for each user endpoint device of a plurality of user endpoint devices, estimates a future data rate for each user endpoint device at the location, estimates future timeslot allocations of each channel of the plurality of channels in the wireless network in accordance with the future data rate that is predicted for each user endpoint device, and allocates each timeslot of the plurality of timeslots of each channel of the plurality of channels in the wireless network to a user endpoint device of the plurality of user endpoint devices in accordance with the future timeslot allocations that are estimated for each channel.Type: GrantFiled: December 23, 2013Date of Patent: May 9, 2017Assignees: AT&T Intellectual Property I, L.P., The Trustees of Columbia University in the City of New YorkInventors: Ashwin Sridharan, Vaneet Aggarwal, Rittwik Jana, Howard Karloff, Nemmara K.

Publication number: 20170093553Abstract: A system and method for establishing windows that govern the exchange of acknowledgements in a full-duplex communication. The window is established for two nodes which transmit asymmetric frame sizes in full-duplex mode. The window is related to the size of the asymmetric frames. Frames are exchanged in full-duplex between the two nodes, and the window size is defined as enabling the nodes to send data until the number of unacknowledged frames at the nodes is less than or equal to the window size, at which point acknowledgments are exchanged simultaneously. In sending the acknowledgment, both nodes can send acknowledgments simultaneously in full-duplex in the same frequency bin.Type: ApplicationFiled: December 9, 2016Publication date: March 30, 2017Inventors: Vaneet Aggarwal, Rittwik Jana, Christopher W. Rice, Nemmara K. Shankaranarayanan

Patent number: 9602448Abstract: Methods and devices for providing presence based messaging are disclosed. For example, a method receives a message including a message content, an identifier of a recipient and a presence parameter. The presence parameter may comprise a speed parameter pertaining to a speed of a device associated with the recipient or a mood parameter pertaining to a mood of the recipient. The method then stores the message and delivers the message to the device associated with the recipient when the presence parameter is satisfied.Type: GrantFiled: June 14, 2012Date of Patent: March 21, 2017Assignee: AT&T Intellectual Property I, L.P.Inventors: Vaneet Aggarwal, Rittwik Jana, Gerald Michael Karam, John F.

Publication number: 20170064350Abstract: A system for resource provisioning for content delivery of multiple services is disclosed. The system may be configured to offer multiple services, wherein at least one first offered service is delivery of prerecorded content and at least one second offered service is content delivered according to a deadline. In at least one embodiment, the first offered service may be video content, and the second offered service may be broadcast television content. The system may also be configured to deliver at least a portion of the first offered service in advance of use of that portion of the first offered service such that resource demand in connection with delivery of service content of the second offered service at peak delivery may be reduced. As such, fewer resources are needed to provide uninterrupted service of the first and second offered services.Type: ApplicationFiled: November 16, 2016Publication date: March 2, 2017Applicant: AT&T Intellectual Property I, L.P.Inventors: Rittwik Jana, Vaneet Aggarwal, Xu Chen, Vijay Gopalakrishnan, Kadangode Ramakrishnan, Vinay Vaishampayan

Publication number: 20170061790Abstract: Vehicle-to-vehicle and vehicle-to-infrastructure communications are accomplished via a scalable ad hoc geographic routing protocol. As vehicles move along roadways, they can query other vehicles and entities for information. Responses to queries can be used to determine information such as traffic conditions, a retail store sale, that a restaurant has tables available, and/or that parking spaces are available, for example. Businesses, vehicles, and other entities along roadways can geocast pertinent information to vehicles passing by. Vehicles can cache information as it is received.Type: ApplicationFiled: November 14, 2016Publication date: March 2, 2017Inventors: Rittwik Jana, Vaneet Aggarwal, Joshua Marc Auzins, Robert J.
