Power control protocol for highly variable data rate reverse link of a wireless communication system
Patent number: 9363759Abstract: A subscriber unit performs power control of a reverse link by sending heartbeat messages to a base station, permitting the base station to determine a reverse link quality report. Using a reverse link quality report message received from the base station, the subscriber unit calculates its reverse power level and maintains the reverse power level during the standby state.Type: GrantFiled: August 23, 2013Date of Patent: June 7, 2016Assignee: IPR Licensing, Inc.Inventor: James A.

Patent number: 9344220Abstract: A transmitter/receiver system for high data transfer in a wireless communication system includes a physical layer processor that comprises an FEC coder, a demultiplexer and a plurality of modem processors. The FEC coder applies error correction codes to the high data rate signal. Thereafter, the demultiplexer distributes portions of the coded high data rate signal to the modem processors. Each modem processor processes its respective portion of the coded signal for transmission in an independent channel.Type: GrantFiled: October 21, 2011Date of Patent: May 17, 2016Assignee: IPR Licensing, Inc.Inventor: James A.

Patent number: 9306658Abstract: A system for wireless data transmission that uses a channel bandwidth, channel separation, and radio frequency power spectrum which is compatible with existing deployments of wireless voice services. The transmitted waveforms are thus compatible with existing cellular networks. However, the time domain digital coding, modulation, and power control schemes are optimized for data transmission. Existing cellular network sites can thus be used to provide a high speed service optimized for wireless data traffic without the need for new radio frequency planning, and without interfering with existing voice service deployments.Type: GrantFiled: May 19, 2014Date of Patent: April 5, 2016Assignee: IPR Licensing, Inc.Inventors: Carlo Amalfitano, James A.

Publication number: 20160050584Abstract: A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections, which conform to a transport layer protocol such as TCP, UDP, and RSTP, and include wireless links, which transmit packets using a radio frequency (RF) medium. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection. Since certain data types, such as streaming audio and video, are more loss tolerant, determination of the data type is used to compute link control parameters for the wireless link which that are optimal to the type of data being transmitted over the link.Type: ApplicationFiled: October 30, 2015Publication date: February 18, 2016Applicant: IPR LICENSING, INC.Inventors: Kevin L.

Publication number: 20160050638Abstract: A method and system are provided for transmitting information in a Mobile Internet Protocol (IP) environment, which includes a home agent (HA) provided at a home network, a base station (BS) broadcasting a pilot signal, a foreign agent (FA) provided at or associated with the BS, a mobile node (MN) providing the ability to detect and identify itself to a BS, a proxy mobile node (PMN) Identifying the MN wherein the PMN is provided at the BS. If the PMN identifies the MN, the PMN retrieves an IP address for each of the MN, FA and HA and sends a registration request to the FA. The FA relays the registration request to the HA, and the proxy MN is registered with the HA. Thus, the MN functionality is provided transparently to the MN by the PMN. This significantly simplifies the configuration of the MN and the Mobile IP network.Type: ApplicationFiled: October 22, 2015Publication date: February 18, 2016Applicant: IPR LICENSING, INC.Inventor: Howard Andrew Heller

Patent number: 9210616Abstract: A packet data system such as a TCP/IP network transmits packets containing a variety of data types along links in the network. Packets are transmitted in a stream between nodes interconnected by the links connections which conform to a transport layer protocol such as TCP, UDP, and RSTP, and includes wireless links, which transmit packets using a radio frequency (RF) medium. Typical protocols, however, are usually developed to optimize throughput and minimize data error and loss over wired links, and do not lend themselves well to a wireless link. By examining the data in a packet, performance characteristics such as a port number are determined. The performance characteristics indicate the application type, and therefore, the data type, of the packets carried on the connection.Type: GrantFiled: May 16, 2011Date of Patent: December 8, 2015Assignee: IPR Licensing, Inc.Inventors: Kevin L.
