Patent number: 8934439Abstract: Methods and system are provided for managing and monitoring allocation of RF spectrum resources based on time, space and frequency. A network may be enabled to allocate excess spectrum resources for use by other network providers on a real-time basis. Allocated resources may be transferred from one provider with excess resources to another in need of additional resources based on contractual terms or on a real-time purchase negotiations and settlements. A network may be enabled to monitor the use of allocated resources on real-time basis and off-load or allow additional users depending on the spectrum resources availability. Public safety networks may be enabled to make spectrum resources available to general public by allocating spectrum resources and monitoring the use of those resources. During an emergency, when traffic increases on a public safety network, the public safety networks may off-load bandwidth traffic to make available necessary resources for public safety users.Type: GrantFiled: March 14, 2013Date of Patent: January 13, 2015Assignee: Rivada Networks, LLCInventors: Clint Smith, Declan Ganley

Patent number: 8879389Abstract: A communications advertising system is described for delivering ad content to subscribers of a telecommunications network. The system performs traffic handling by using at least two limits for regulating message transmission. During processing, a network node of the system can continuously monitor the quantity of message traffic being processed. If the node detects that the quantity of traffic has decreased below a first limit, it can initiate the processing of reserved bulk messages. The node then continues to transmit the bulk traffic while still measuring the quantity of message traffic being processed. If, thereafter, the node detects that the quantity of overall message traffic being processed has exceeded a second limit, the processing of bulk messages is halted until the quantity of regular traffic decreases below the first limit once again, at which point the node can resume processing the bulk message traffic.Type: GrantFiled: November 12, 2010Date of Patent: November 4, 2014Assignee: Oracle International CorporationInventors: Amitha Pulijala, Terje Strand, Sharath Rajasekar

Patent number: 8848631Abstract: Interference between users in an MU-MIMO system is minimized by effective precoding, without increasing an overhead of control data. In a wireless communication system in which multiplex communication is possible between multiple UE1, UE2, and BS, a channel estimation and precoding selection unit 539 in BS estimates channels from the respective UE1, UE2 to the BS, determines a precoding matrix P from a projection matrix to make the two channel response matrices orthogonal or nearly orthogonal, and feeds back the precoding matrix P to UE2, and executes precoding on only UE2 of the two. A precoding unit 524 in the UE2 employs the precoding matrix P that has been notified to perform precoding of a data stream, and sends the precoded data stream to the BS.Type: GrantFiled: August 31, 2009Date of Patent: September 30, 2014Assignee: Panasonic Intellectual Property Corporation of AmericaInventors: Qian Yu, Masayuki Hoshino, Daichi Imamura, Megumi Ichikawa

Patent number: 8842693Abstract: Systems and methodologies are described that facilitate reducing rank (e.g., of a user device) as a number of transmissions there from increases. Such rank step-down can improve interference resistance and facilitate maintaining code rate despite transmission propagation. Additionally, rank step-down information can be encoded along with CQI information to generate a 5-bit CQI signal that can facilitate updating a user's rank upon each CQI transmission (e.g., approximately every 5 ms).

Patent number: 8767572Abstract: Disclosed herein are methods and systems according to which an access terminal intelligently accounts for differences in respective distances between itself and various access nodes, so as to more accurately estimate the C/I ratio of signals received from a serving access node. According to the method, the access terminal calculates a delta of (i) a serving distance between the access terminal and the serving access node and (ii) a neighboring distance between the access terminal and a neighboring access node. The access terminal then selects a C/I-evaluation time period based at least in part on the calculated delta, which may generally be used by the access terminal to select the C/I-evaluation time period such that this time period only includes time during which the access terminal is likely to have received signals emitted by both the serving access node and the neighboring access node.Type: GrantFiled: May 17, 2011Date of Patent: July 1, 2014Assignee: Sprint Spectrum L.P.Inventors: Sachin R. Vargantwar, Jason P. Sigg

Patent number: 8743913Abstract: A distributed DSLAM, which comprises a head end subsystem located within a switching facility and a remote subsystem located outside of the switching facility. The head end subsystem is operative for routing streams of data from a data network to the remote subsystem over a communication link, while the remote subsystem is operative for transmitting over a set of local loops analog signals comprising digitally modulated versions of the data. Separating the routing and modem functionality between inside and outside plant facilities reduces heat dissipation in the outside plant, leading to increased reliability. Flow control can be performed in the upstream and downstream directions by transmitting portions of individual packets and withholding other portions of individual packets. This is done instead of withholding the transmission of entire packets. As a result, the perceived impact on video quality, for example, is lessened.Type: GrantFiled: March 23, 2011Date of Patent: June 3, 2014Assignee: Telekom Malaysia BerhadInventors: Azrin Bin Aris, Siti Sawiah Binti Ramli, Muhammad Fahmy Bin Khyasudeen, Tet Hin Yeap
