Patent number: 10805887Abstract: 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: August 19, 2019Date of Patent: October 13, 2020Assignee: IPR LICENSING, INC.Inventors: James A.

Patent number: 10708909Abstract: 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: May 17, 2018Date of Patent: July 7, 2020Assignee: IPR Licensing, Inc.Inventors: John B.

Publication number: 20170156139Abstract: 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: ApplicationFiled: April 22, 2013Publication date: June 1, 2017Applicant: IPR Licensing, Inc.Inventors: John B.

Patent number: 9661583Abstract: In an illustrative embodiment of the present invention, a reference signal including pilot information is transmitted from a base station to one or multiple field units over a pilot channel. A message is also sent to the field units over a paging channel to indicate an effective radiated power level at which the reference signal is transmitted on the pilot channel. Based on a received power level of the reference signal at a field unit and the effective radiated power level of the reference signal, a forward path loss is estimated at the field unit for the forward link between the base station and field unit. Assuming the path loss in the reverse link is approximately the same as the estimated forward link path loss, the field unit can transmit, a reply message in the reverse link so that the base station generally receives a message at-a desired power level.Type: GrantFiled: August 9, 2013Date of Patent: May 23, 2017Assignee: IPR Licensing, Inc.Inventors: George R.

Publication number: 20160323074Abstract: A method and apparatus for encoding digital communication signals is described herein. A wireless communication unit may comprise a processor configured to produce first symbols derived from data bits and parity bits. The wireless communication unit may transmit a wireless signal including the first symbols and reference symbols in a time interval including a plurality of symbol time intervals. In one of the symbol time intervals a plurality of the reference symbols may be transmitted in a predetermined pattern, which may have the reference symbols not adjacent to each other. A base station may receive a wireless signal including first and reference symbols. In one of the symbol time intervals a plurality of the reference symbols may be received in a predetermined pattern. The base station may then demodulate the first symbols using the reference symbols, wherein the first symbols are derived from data bits and parity bits.Type: ApplicationFiled: July 15, 2016Publication date: November 3, 2016Applicant: IPR Licensing, Inc.Inventors: John E.
