Patent number: 10390311Abstract: In a reverse link of a wireless CDMA communication system, a method of maintaining an idling mode connection between a field unit and a base transceiver station is provided using various techniques to maintain the idle mode connection at a reduced power level. A preferred embodiment computes a time slot or frame offset based on modulo function using a field unit identifier in order to distribute field unit maintenance transmissions among available slots or offsets. An alternate embodiment detects explicit signaling states changes at the physical layer and causes power target changes. A further embodiment transmits maintenance data during predetermined time intervals, coordinated between the field units and BTS, allowing power levels to be adjusted accordingly.Type: GrantFiled: December 4, 2013Date of Patent: August 20, 2019Assignee: IPR Licensing, Inc.Inventors: James A.

Patent number: 8964909Abstract: The present invention provides for making code rate adjustments and modulation type adjustments in a pseudonoise (PN) encoded CDMA system. Coding rate adjustments may be made by changing the number of information bits per symbol, or Forward Error Code (FEC) coding rate. A forward error correction (FEC) block size is maintained at a constant amount. Therefore, as the number of information bits per symbol are increased, an integer multiple of bits per epoch is always maintained. The scheme permits for a greater flexibility and selection of effective data rates providing information bit rates ranging from, for example, approximately 50 kilobits per second to over 5 mega bits per second (Mbps) in one preferred embodiment.Type: GrantFiled: June 11, 2012Date of Patent: February 24, 2015Assignee: Intel CorporationInventors: John E. Hoffman, George Rodney Nelson, Jr., Daniel I. Riley, Antoine J. Rouphael, James A. Proctor, Jr.

Patent number: 8811367Abstract: Data rate allocation decisions are made for a communications channel. A message is sent on a communication channel such as on a paging channel. The message indicates a forward Effective Radiate Power (ERP) of a pilot signal transmitted. The remote station then determines the received signal strength of this pilot signal, taking into account receiver gains. The path loss may be estimated as the difference between the forward ERP data value received and the detected received pilot power. This transmit power level information is encoded as a digital data word together with the forward path loss information. Upon transmission, the forward path loss estimate as calculated and the output power value can then help determine the amount of excess power available. This is indicative of the amount of dynamic range available in the transmit power amplifier. Coding rates which require a higher dynamic range may be acceptable for use.Type: GrantFiled: December 6, 2005Date of Patent: August 19, 2014Assignee: IPR Licensing, Inc.Inventors: George Rodney Nelson, Jr., James A.

Patent number: 8462689Abstract: A technique for a time division multiplex system in which access to shared broadcast communication media is granted on a demand basis. Particular connections are assigned slot times at the transmitter based on demand. However, no specific information regarding the assignment of time slots need be communicated to the receivers. The transmit side employs a forward error correction technique followed by multiplication by a cover sequence unique to each connection. All receivers listen to the broadcast transmission channel all of the time. The receiver assigned to each connection decodes the signals in such a manner that only the receiver with the correct cover sequence assigned to a particular connection will successfully decode the data associated with that connection. Data frames that fail the forward error correction process are discarded, and only those frames which are successfully decoded are passed up to a higher layer.Type: GrantFiled: December 22, 2004Date of Patent: June 11, 2013Assignee: Intel CorporationInventors: Kevin P. Johnson, Antoine J. Rouphael, George Rodney Nelson, Jr.

Patent number: 8432876Abstract: A control channel supporting traffic control in epochs is divided into two control subchannels each being less than or equal to about a half epoch in duration and occurring serially in time. Slot allocation data may be transmitted and received independently over the subchannels. One subchannel may be used for transmitting forward slot allocation data and the other subchannel may be used for transmitting reverse slot allocation data. The channel split into two subchannels may be a paging channel. The forward and reverse slot allocation data may be transmitted between a base station processor and field unit. Forward and reverse traffic data may be staggered by at least about half an epoch. Transmission of traffic data happens within about two epochs after the assignments.Type: GrantFiled: March 12, 2009Date of Patent: April 30, 2013Assignee: IPR Licensing, Inc.Inventors: John B. Cornett, Jr., Kevin P. Johnson, George Rodney Nelson, Jr.

Patent number: 8320298Abstract: Parallel demodulators are provided in field units. Forward and reverse channel allocation information may be broadcast to the field units in the same epoch as traffic data but on first and second channels, such as paging and traffic channels. This assures that all field units are able to receive forward and reverse channel allocation information every epoch. By having parallel demodulators in the field unit, switching between the first and second channels is avoided and channel allocation information is not lost.Type: GrantFiled: January 22, 2003Date of Patent: November 27, 2012Assignee: IPR Licensing, Inc.Inventors: John B.

Patent number: 8296455Abstract: A personal computer's (PC) microprocessor is used to provide both the physical layer (PHY) and media access control (MAC) processing functions required to implement a wireless local area network (WLAN) adapter. This technique uses the polling mechanism associated with the power save (PS) functionality of WLAN protocol to relieve networking stress on the host processing system. It does this while maintaining networking integrity and packet delivery. The WLAN protocol polling mechanism is used to briefly inhibit the transfer of packets from the WLAN access point (AP) during peak periods of network traffic and/or host processor loading. Because the modulation, demodulation, and MAC functions, typically implemented in dedicated hardware on existing adapters are implemented in software running on the host PC microprocessor, other host system processes and applications can interfere with these time critical functions.Type: GrantFiled: August 15, 2007Date of Patent: October 23, 2012Assignee: Intellectual Ventures I LLCInventors: Richard Douglas Schultz, George Rodney Nelson, Jr., John Erich Hoffmann

Publication number: 20120087364Abstract: A technique for encoding digital communication signals. Data symbols are augmented in pilot symbols inserted at predetermined positions. The pilot augmented sequence is then fed to a deterministic error correction block encoder, such as a turbo product coder, to output a coded sequence. The symbols in the error correction encoded sequence are then rearranged to ensure that the output symbols derived from input pilot symbols are located at regular, predetermined positions. As a result, channel encoding schemes can more easily be used which benefits from power of two length block sizes.Type: ApplicationFiled: December 5, 2011Publication date: April 12, 2012Applicant: IPR LICENSING, INC.Inventors: John E.

Patent number: 7613227Abstract: A single, common correlation filter (CF) core is provided in a receiver for recovery of data from received code division multiple access (CDMA) signals. Signals are received over CDMA channels with different data rates, where the received signals include user information such as pilot and data symbols that have been spread according to different despreading rates including tier 1, tier 2 and tier 3 rates, where tier 1 is the smallest despreading rate. The received signal is correlated at the smallest despreading rate in the correlation filter (CF) by time multiplexing delayed versions of the pseudorandom noise (PN) code. The correlated information is then demultiplexed and pilot-aided QPSK demodulated. The demodulated information is summed at the proper integer multiple of the tier 1 rate to achieve tier 2 and tier 3 despreading rates. According to an embodiment, the three strongest multipaths components in terms of the received power are selected in a window or time period for optimal information recovery.Type: GrantFiled: September 17, 2007Date of Patent: November 3, 2009Assignee: IPR Licensing, Inc.Inventors: Antoine J.
