Method of exchanging data packages between first and second portable communication devices using a favoured frequency band
First Claim
1. A method of exchanging data packages between a first portable communication device and a second portable communication device over a bi-directional wireless communication channel, where at least one of the first and second portable communication devices comprises a hearing instrument, the method comprising:
- generating, by the first portable communication device, a first plurality of data packages;
transmitting the first plurality of data packages from the first portable communication device to the second portable communication device through a plurality of spaced apart frequency bands distributed across a radio frequency range of the bi-directional wireless communication channel;
computing, at the first wireless communication device or at the second wireless communication device, transmission quality estimators for the respective spaced apart frequency bands;
determining a favoured frequency band based on the transmission quality estimators; and
transmitting, from the first portable communication device to the second portable communication device, a second plurality of data packages on the favoured frequency band, the second plurality of data packages comprising a first data package;
wherein if the transmission of one of the second plurality of data packages fails, the method further comprises;
selecting, in accordance with a frequency hopping key, a frequency band of the plurality of spaced apart frequency bands that is different from the favoured frequency band; and
retransmitting the one of the second plurality of data packages on the different frequency band.

Abstract
The present disclosure relates in a first aspect to a method of exchanging data packages between a first portable communication device and a second portable communication device over a bi-directional wireless communication channel, where at least one of the first and second portable communication devices comprises a hearing instrument. The method comprises generating, by the first portable communication device, a plurality of data packages over time and transmitting the plurality of data packages from the first to the second portable communication device through a plurality of spaced apart frequency bands distributed across a predetermined radio frequency range of the bi-directional wireless communication channel. The method further comprises computing, at the first wireless communication device or at the second wireless communication device, respective transmission quality estimators of the plurality of spaced apart frequency bands and determining a favored frequency band based on the detected transmission quality estimators.

14. A method of exchanging data packages between a first portable communication device and a second portable communication device over a bi-directional wireless communication channel, where at least one of the first and second portable communication devices comprises a hearing instrument, the method comprising:
-
generating, by the first portable communication device, a first plurality of data packages; transmitting the first plurality of data packages from the first portable communication device to the second portable communication device through a plurality of spaced apart frequency bands distributed across a radio frequency range of the bi-directional wireless communication channel; computing, at the first wireless communication device or at the second wireless communication device, transmission quality estimators for the respective spaced apart frequency bands; determining a favoured frequency band based on the transmission quality estimators; and transmitting, from the first portable communication device to the second portable communication device, a second plurality of data packages on the favoured frequency band, the second plurality of data packages comprising a first data package; wherein a first subset of the second plurality of data packages transmitted by the first portable communication device belongs to a first packet category comprising audio data, and a second subset of the second plurality of data packages belongs to a second packet category without audio data; wherein if the transmission of one of the second plurality of data packages fails, the method further comprises retransmitting the one of the second plurality of data packages for at most N times if the one of the second plurality of data packages belongs to the first packet category; and wherein N is a positive integer between 1 and 4.

15. A method of exchanging data packages between a first portable communication device and a second portable communication device over a bi-directional wireless communication channel, where at least one of the first and second portable communication devices comprises a hearing instrument, the method comprising:
-
generating, by the first portable communication device, a first plurality of data packages; transmitting the first plurality of data packages from the first portable communication device to the second portable communication device through a plurality of spaced apart frequency bands distributed across a radio frequency range of the bi-directional wireless communication channel; computing, at the first wireless communication device or at the second wireless communication device, transmission quality estimators for the respective spaced apart frequency bands; determining a favoured frequency band based on the transmission quality estimators; transmitting, from the first portable communication device to the second portable communication device, a second plurality of data packages on the favoured frequency band, the second plurality of data packages comprising a first data package; receiving a second data package at the first portable communication device; and checking an error-detection code of the second data package subsequent to receipt of the second data package at the first portable communication device; wherein if the error-detection code indicates invalid data of the second data package, the method further comprises ignoring a setting of an acknowledgment indicator of the second data package, and unsetting an acknowledgment indicator of a third data package to reflect a failed receipt of the second data package.
