Abstract

A communication system and a method for transmitting data over a communication network includes a processing module arranged for selectively splitting a traffic demand of a transmission link into a plurality of portions of traffic demands distributed over a main channel and at least one auxiliary channel of the communication network, and the processing module is further arranged to determine a data transmission relationship associated with the traffic demand of the transmission link and at least one parameter of both the main channel and the at least one auxiliary channel; and a transmission module arranged to transmit data over one or more of the main channel and the at least one auxiliary channel according to the data transmission relationship.

First claim

1 . A method for transmitting data over a communication network, comprising the steps of:
selectively splitting a traffic demand of a transmission link into a plurality of portions of traffic demands distributed over a main channel and at least one auxiliary channel of the communication network; determining a data transmission relationship associated with the traffic demands of the transmission link and at least one parameter of both the main channel and the at least one auxiliary channel; and transmitting data over one or more of the main channel and the at least one auxiliary channel according to the data transmission relationship.

2 . A method for transmitting data in accordance with claim 1 , wherein the at least one parameter of the at least one auxiliary channel includes an interference in the at least one auxiliary channel which occurs when the data is transmitted over the at least one auxiliary channel.

3 . A method for transmitting data in accordance with claim 2 , wherein the interference is uncontrollable.

4 . A method for transmitting data in accordance with claim 1 , wherein the at least one parameter is associated with a transmission resource allocation of both the main channel and the at least one auxiliary channel.

5 . A method for transmitting data in accordance with claim 4 , wherein the transmission resource allocation includes at least one of a transmission power of the data, a data transmission rate, a channel power gain and a bandwidth of each of the main channel and the at least one auxiliary channel.

6 . A method for transmitting data in accordance with claim 4 , wherein the data transmission relationship is further associated with an outage-probability when at least a portion of the data is transmitted over the at least one auxiliary channel.

7 . A method for transmitting data in accordance with claim 6 , wherein the outage-probability is associated with the transmission resource allocation of the at least one auxiliary channel.

8 . A method for transmitting data in accordance with claim 7 , wherein the outage-probability is represented by:

g A denotes a channel power gain of the at least one auxiliary channel;
n A denotes a power of a background noise of the at least one auxiliary channel;
W A denotes a bandwidth of the at least one auxiliary channel; and
I A represents a random interference.

9 . A method for transmitting data in accordance with claim 8 , wherein the outage-probability is further associated with a power of random interference M A following an on-off distribution represented by:
Probability{ I A =M A }=θ A and Probability{ I A =0}= 1 −θ A ; and
wherein θ A represents a presence of the interference in the at least one auxiliary channel.
