Method And Apparatus For Enhancing Performance Of Channel Quality Indicator (Cqi) Channel In Wireless Communications System
view source
US Patent:

7317702, Jan 8, 2008
Filed:

Jul 30, 2004
Appl. No.:

10/903994
Inventors:

Francis Dominique - Rockaway NJ, US
Hongwei Kong - Denville NJ, US
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04Q 7/00
US Classification:

370328, 370333, 370310, 455 69, 455 671
Abstract:

The channel quality indicator (CQI) transmitted by a mobile terminal to a base station is indicative of the E/Npilot SNR of the pilot signal transmitted by the base station and measured by the mobile terminal. The base station uses the CQI for purposes such as determining a downlink rate, a modulation scheme, and downlink power. Knowledge by the base station of whether the received and detected CQI is likely to be “good” or “bad” would be useful in determining how and whether the value of the received and detected CQI should be used. In a first embodiment, at the base station, a reliability of the received CQI that is detected from received soft symbol metrics is determined in conjunction with the detected CQI value for the received CQI word as a whole. In a second embodiment, a minimum bit error probability receiver is used that makes a maximum likelihood decision for each CQI bit individually from the plurality of metrics derived from the received soft symbol metrics, and the reliability of each CQI bit is individually determined.

US Patent:

7356749, Apr 8, 2008
Filed:

Feb 2, 2004
Appl. No.:

10/770028
Inventors:

Francis Dominique - Rockaway NJ, US
Srinivas R. Kadaba - Chatham NJ, US
Hongwei Kong - Denville NJ, US
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

G08C 25/02
US Classification:

714748, 714749
Abstract:

A decision as to whether a mobile terminal has transmitted an ACK, a NACK or a NULL from a received signal at a base station is made by successively eliminating one of the three possible transmitted symbols by sequentially applying decision rules that maximize network throughput by minimizing the sum of the weighted costs of making a decision based on the magnitude of the received signal.

US Patent:

7376208, May 20, 2008
Filed:

May 13, 2004
Appl. No.:

10/844803
Inventors:

Francis Dominique - Rockaway NJ, US
Hongwei Kong - Denville NJ, US
Ashok Armen Tikku - Morristown NJ, US
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H04L 27/06
US Classification:

375340, 375238, 375239, 375242, 375256, 375257, 375332, 375348, 375361, 375370, 375381
Abstract:

A decoding method is carried out in a receiver configured to accept format information relating to sequences of input data, to use format information in the decoding of each input sequence, and to issue an acknowledgement signal in the event that an input sequence is successfully decoded. The method involves receiving a format message pertaining to a new input sequence, searching a candidate set of format indices an index best satisfying a criterion for matching to the format message, and selecting the index giving the best match. Before searching, the receiver reads the acknowledgement signals issued in response to the decoding or attempted decoding of recent input sequences. If the acknowledgement signals satisfy an appropriate condition, the search is limited to fewer than all the indices in the candidate set. The format information that corresponds to the selected index is used in decoding the new input sequence.

Filed:

Mar 31, 2003
Appl. No.:

10/401594

International Classification:

H04Q 7/00
US Classification:

370328, 370342, 370345, 370441, 370442, 455 631, 455513, 375144, 375346
Abstract:

In a method of canceling interference, a base station selects a known highest data rate user transmission from a received first signal containing a group of user transmissions. The known highest rate user transmission may be configured as one or more frames, each frame including a control preamble and a plurality of encoded sub-frames. The control preamble and encoded sub-frames may be decoded, and the decoded sub-frames may be used for removing interference caused by the known highest rate user transmission to all remaining transmissions of the group.

Method And Apparatus For Preventing A False Pass Of A Cyclic Redundancy Check At A Receiver During Weak Receiving Conditions In A Wireless Communications System

10/823948
Inventors:

Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H03M 13/45
H03M 13/41
US Classification:

714780, 714794, 714795
Abstract:

At the receiver in a wireless communications system, the likelihood of a false CRC pass that can occur when a weak received signal produces an all ZERO output from a convolutional or a turbo decoder is minimized. To prevent an all ZERO output, a convolutional decoder selects from among those determined equally most likely transmitted sequences of bits in a data block one that has a weight greater than the one having the minimum weight. A turbo decoder selects a ONE rather than a ZERO as the value of a transmitted bit in a data block when for that bit a bit value of a ZERO and a ONE are determined to be equally likely.

Method And Apparatus For Detecting A Packet Error In A Wireless Communications System With Minimum Overhead Using Tail Bits In Turbo Code

US Patent:

7395492, Jul 1, 2008
Filed:

Sep 13, 2004
Appl. No.:

10/939718
Inventors:

Francis Dominique - Rockaway NJ, US
Hongwei Kong - Denville NJ, US
Assignee:

Lucent Technologies Inc. - Murray Hill NJ
International Classification:

H03M 13/03
US Classification:

714794, 714795, 375262, 375341
Abstract:

The need for separate CRC bits is eliminated by taking advantage of what has been determined to be an embedded error detection capability of the tail bits generated by the constituent encoders of a turbo coder to perform error detection following turbo decoding. Specifically, it has been recognized that the tail bits are similar to CRC bits that would be generated by a CRC encoder that uses as its generating polynomial the feedback polynomial used by the turbo encoder. At the turbo decoder, after a final turbo decoding iteration cycle, a check is performed on the decoded systematic information bits by calculating the tail bits from the decoded information bits using that generating polynomial and bit-by-bit comparing the calculated tail bits with the systematic tail bits decoded by the turbo decoder. If a mismatch occurs at one or more bit positions, an error is indicated.

US Patent:

7417569, Aug 26, 2008
Filed:

Nov 30, 2006
Appl. No.:

11/565086
Inventors:

Hongwei Kong - Denville NJ, US
Assignee:

Broadcom Corporation - Irvine CA
International Classification:

H03M 7/00
US Classification:

341 61, 341155
Abstract:

Aspects of a sampling rate converter with no timing drift and with bounded amplitude error are presented. Aspects of the method may include computing an intermediate sum by adding a numerator portion of a fractional conversion ratio to an accumulated time value upon receipt of an input data sample. A time instant for generating an output data sample may be determined by computing a modulus value for the intermediate sum, wherein a base for the modulus value computing may be a denominator portion of the fractional conversion ratio.
