Abstract

Techniques are directed to opportunistically communicating using a modulation scheme that is other than the preferred modulation scheme, to update communication metric data for the second modulation scheme, such as a modulation scheme that has not been used as much as the first modulation scheme. The second modulation scheme may be associated with a higher data rate than the preferred modulation scheme. If communication using the second modulation scheme is successful, subsequent communication may be carried out exclusively using the second modulation scheme, and the communication metrics may develop such that the second modulation scheme becomes the preferred modulation scheme.

Dependent claims

A network communication device, comprising:

one or more processors;
and
memory coupled to the one or more processors, the memory storing instructions executable by the one or more processors to perform operations including:
based at least in part on a stored indication of a first transmission characteristic, transmitting a first data item to another network communication device over a link using the first transmission characteristic, wherein the first transmission characteristic is based at least on observed behavior of the link;
based at least in part on a determined availability of a second transmission characteristic for the link that is different from the first transmission characteristic, transmitting a second data item over the link using the second transmission characteristic, wherein transmitting the second data item over the link using the second transmission characteristic is further based at least in part on application of an algorithm;
determining that the transmission of the second data item is successful;
and
based at least in part on the transmission of the second data item being successful, transmitting a third data item over the link using the second transmission characteristic.

A method, comprising:

based at least in part on a stored indication of a first transmission characteristic, transmitting, by a first network communication device, a first data item to a second network communication device over a link using the first transmission characteristic, wherein the first transmission characteristic is based at least on observed behavior of the link;
based at least in part on a determined availability of a second transmission characteristic for the link that is different from the first transmission characteristic, transmitting, by the second network communication device, a second data item over the link using the second transmission characteristic, wherein transmitting the second data item over the link using the second transmission characteristic is further based at least in part on application of an algorithm;
and
based at least in part on the transmission of the second data item being successful, transmitting, by the first network communication device, a third data item over the link using the second transmission characteristic.
