20110222528, Sep 15, 2011

Filed:

Dec 15, 2010

Appl. No.:

12/968677

Inventors:

Jie Chen - Land O Lakes FL, US

International Classification:

H04J 3/06

US Classification:

370350

Abstract:

Systems, methods, articles of manufacture and apparatus are disclosed to align actions of audio source monitors. An example method disclosed herein includes invoking an audience monitor to transmit a radio frequency (RF) initialization packet to a base unit, receiving an indication that the base unit has received the RF initialization packet at a first time, and invoking the base unit to transmit an RF acknowledgement packet to the audience monitor. The example method also includes receiving an indication that the RF acknowledgement packet is received by the audience monitor and waiting for an end to a delay period having a first value, identifying whether the audience monitor has finished processing the RF acknowledgement packet when the delay period ends at a second time, and incrementing the delay period to a second value when the audience monitor is still processing the RF acknowledgement packet and the delay period has ended.

Inventors:

Jie Chen - Land O Lakes FL, US

International Classification:

H04R 29/00

US Classification:

381 58

Abstract:

A disclosed example method to determine a location of an audience member involves generating a correlation analysis result based on correlating first audio samples from a stationary audio detector with second audio samples from a portable audio detector carried by the audience member and determining via a neural network the location of the audience member based on the correlation analysis result.

International Classification:

H04W 52/02

Abstract:

Certain example embodiments provide systems, methods, apparatuses, and computer program products for determining radio frequency (RF) conditions using sensing information. A network node may construct a map of RF conditions associated with location information within its coverage area. The network node may configure a radio resource control (RRC)-connected UE to operate in an RF sensing mode. The network node may obtain a positioning of the UE from a sensing node. The network node may determine the RF conditions of the UE based on its position using the map.

International Classification:

H04L 1/00

Abstract:

A method for encoding a sequence of control information bits comprising: generating a sequence of error detection bits based on the sequence of control information bits; generating a sequence of error correction bits based on the sequence of control information bits; and distributing the sequence of error detection bits and the sequence of error correction bits between the sequence of control information bits to form a combined sequence of bits, such that the bit order of the combined sequence of bits following the distribution enables an error detection check to be performed before or after a first error correction check bit.

Abstract:

A method including determining a cyclic redundancy check (CRC) generator sequence defining a one to one mapping between a sequence of control information values and cyclic redundancy check (CRC) sequence values; and determining a combined sequence, the combined sequence formed by distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values, wherein the distributing the cyclic redundancy check (CRC) value sequence within the sequence of control information values is based on a selected part of the cyclic redundancy check (CRC) generator sequence.

International Classification:

H04L 5/00
H04L 1/00
H04B 7/06

Abstract:

Embodiments described herein encode data for multiple-segment transmission in a communication channel by encoding payload bits with an outer code and distributing the outer encoded payload bits to a plurality of N element coders, where N is an integer greater than one. At each of the N element coders the respectively input outer encoded payload bits are encoded with a respective element code. Outputs of the N element coders are encoded with an inner code such that the inner code applied to at least one of the outputs of the N element coders is a function of the output of at least one other of the N element coders. Finally, N discrete inner coded outputs are provided for transmission in respective N discrete segments of a wireless channel. The examples present polar element coders and the inner code combines outputs of certain element coders with an exclusive-OR function.
