Publication number: 20230239849Abstract: Methods and apparatus for communicating and utilizing persistent allocation of resources are described herein. A base station may allocate persistent resources to a client station, and may associate the client station or persistent resource allocation with a particular shared NACK channel. The base station may monitor the NACK channel for a NACK indicating a map error. The base station may monitor the resource allocation to implicitly determine a map error. The base station may resend one or more persistent resource allocation information elements in response to the NACK or implicit error determination. A client station having a persistent resource allocation may monitor persistent resource allocation information elements in map messages and/or may indicate failure to receive a persistent resource allocation information element in a NACK message on a shared NACK channel.Type: ApplicationFiled: March 21, 2023Publication date: July 27, 2023Applicant: Wi-LAN Inc.Inventors: Yair Bourlas, Kirupairaj Asirvatham

Patent number: 8196024Abstract: The subject matter disclosed herein provides methods and systems for converting fixed-point soft bit values, provided by a demapper, into floating-point soft bits values. In one aspect, there is provided a method. The method may include receiving, from a demapper, soft bits formatted as a fixed-point value. Moreover, the soft bits may be converted from the fixed-point value to a floating-point value. The floating-point value is punctured to remove a bit. The converted soft bits are provided to a buffer to enable decoding of the buffered soft bits. Related systems, apparatus, methods, and/or articles are also described.Type: GrantFiled: June 27, 2008Date of Patent: June 5, 2012Assignee: Wi-LAN Inc.Inventors: Kirupairaj Asirvatham, Peifang Zhang, Siavash Sheikh Zeinoddin, Peter J.

Patent number: 7379514Abstract: A communications receiver is provided that includes a first and second compensators a pilot tracker and a demodulator. The first compensator is operable to adjust an input signal based on both a coarse frequency offset and a fine frequency offset to produce an adjusted input signal. The pilot tracker determines an estimated residual frequency offset based on at least a portion of the adjusted input signal. The demodulator determines at least a first symbol sequence and a second symbol sequence based on the adjusted input signal. The second compensator is operable to adjust the first symbol sequence and the second symbol sequence based on the estimate residual frequency offset.Type: GrantFiled: January 28, 2005Date of Patent: May 27, 2008Assignee: Texas Instruments IncorporatedInventors: John R. Rosenlof, Kirupairaj Asirvatham, Srikanth Gummadi
