Feedback management in a multipath communication network
First Claim
1. A method of managing feedback messages in a multipath communication network utilised to transmit, between a first communication device and a second communication device, a data stream in real time by using a set of communication paths comprising plural communication paths associated with the data stream,the method comprising:
- determining at least one transmission condition on at least one communication path and at least one transmission constraint for at least one feedback message;
selecting a plurality of communication paths out of the set of communication paths between the first communication device and the second communication device in order to transmit, in synchronization, a plurality of feedback messages from the first communication device to the second communication device over the plurality of communication paths respectively; and
wherein said selecting is based on the at least one transmission condition on the at least one communication path and the at least one transmission constraint for the at least one feedback message.

Abstract
A method of managing feedback messages in a multipath communication network, the method comprising selecting at least one communication path out of a set of communication paths between a first communication device and a second communication device in order to transmit at least one feedback message from the first communication device to the second communication device. The selecting is based on a correlation between at least one transmission condition on said at least one communication path and at least one transmission constraint for said at least one feedback message.
Embodiments make it possible to provide optimal transmission of feedback messages in a multipath context.
