Phase-Noise Resilient Generation Of A Channel Quality Indicator

View page
US Patent:
8477888, Jul 2, 2013
Filed:
Jun 24, 2008
Appl. No.:
12/145322
Inventors:
Feng Lu - Sunnyvale CA, US
Prashant Udupa Sripathi - San Jose CA, US
Liang Zhao - Campbell CA, US
Subramanya P. Rao - Santa Clara CA, US
Assignee:
QUALCOMM Incorporated - San Diego CA
International Classification:
H03D 1/04
US Classification:
375346, 375316
Abstract:
System(s) and method(s) are provided for generating phase-noise resilient channel quality indicator(s). A pilot signal utilized to determine a channel quality indicator is rotated to be aligned to a phase reference signal. Separate noise evaluations in quadrature and in-phase directions are utilized, at least in part, to generate a net noise estimate that is phase-noise compensated or resilient. For example, various combination schemes of quadrature and in-phase noise evaluations can be exploited to generate a net noise estimate, the schemes include weighted average of in-phase and quadrature noise estimates and running averages thereof. Simulation of net noise estimates as a function of geometry conditions reveal that the combination schemes provide substantive mitigation of phase-noise, thus making CQI generation phase-noise resilient.

US Classification:
375148
Abstract:
Methods and systems for multi-user detection in the presence of multiple spreading factors are provided. In one aspect of the disclosure, an apparatus is provided. The apparatus comprises an interference computation unit configured to compute a combined interference based on detected user symbols for a first spreading factor and detected user symbols for a second spreading factor, wherein the combined interference accounts for multi-user interference from user symbols for the first and second spreading factors. The apparatus further comprises an interference cancellation unit configured to remove the computed combined interference from a plurality of received symbols corresponding to the first spreading factor and a redetection unit configured to redetect the user symbols for the first spreading factor from the plurality of received symbols with the computed combined interference removed.

Data Classification In A Wireless Communication System

US Patent:
8578250, Nov 5, 2013
Filed:
Sep 8, 2011
Appl. No.:
13/227906
Inventors:
Prashant Udupa Sripathi - Santa Clara CA, US
Jittra Jootar - Santa Clara CA, US
Je Woo Kim - Santa Clara CA, US
Feng Lu - Santa Clara CA, US
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H03M 13/00
H03M 13/03
US Classification:
714780, 714795
Abstract:
A method of data classification for use in a wireless communication system includes obtaining decoder metrics from a decoder. The decoder metrics correspond to data generated by the decoder. The decoder metrics include a first metric and a second metric. The method also includes classifying the data into a first category if the data fails an error detection check, into a second category if the data passes the error detection check and is determined to be unreliable, or into a third category if the data passes the error detection check and is determined to be reliable. A reliability of the data is determined based on at least one of the decoder metrics and a threshold.

US Patent:
8612825, Dec 17, 2013
Filed:
Sep 8, 2011
Appl. No.:
13/227884
Inventors:
Prashant Udupa Sripathi - Santa Clara CA, US
Jittra Jootar - Santa Clara CA, US
Je Woo Kim - Santa Clara CA, US
Feng Lu - Santa Clara CA, US
Assignee:
Qualcomm Incorporated - San Diego CA
International Classification:
H03M 13/00
H03M 13/03
US Classification:
714758, 714795, 714704, 714780
Abstract:
A method of data classification for use in a wireless communication system includes obtaining decoder metrics from a decoder. The decoder metrics correspond to data generated by the decoder. The decoder metrics include a symbol error rate (SER) and an energy metric (EM). The method also includes classifying the data into a first category if the data fails a cyclic redundancy check (CRC) check, into a second category if the data passes the CRC check and is determined to be unreliable, or into a third category if the data passes the CRC check and is determined to be reliable. A reliability of the data is determined based on the decoder metrics and an EM threshold.

US Patent:
20190068260, Feb 28, 2019
Filed:
Aug 23, 2018
Appl. No.:
16/110610
Inventors:
- San Diego CA, US
Supratik BHATTACHARJEE - San Diego CA, US
Gregory FOERSTER - San Diego CA, US
Prashant Udupa SRIPATHI - San Jose CA, US
International Classification:
H04B 7/06

Abstract:
Methods and apparatuses relate to sounding reference signal (SRS) transmit antenna selection in wireless communication systems. For example, a user equipment (UE) may select, from a set of antennas, a subset of antennas for SRS transmission based on at least one antenna selection parameter.
