Technical field
The present invention relates to wireless communication technology field, and in particular to a kind of data of cooperation communication system and energy cooperation part
Method.
Background technology
Rise of the people to the growing interest and global warming of wireless network energy expenditure promotes people's research and development can dose-effect
The higher communication technology of rate.From regenerative resource such as solar energy, wind energy, heat energy and radio frequency (radio frequency, RF) energy
Communication equipment and network can be driven by obtaining energy collection technology (energy harvesting, EH) technology of energy, to realize
Green communications present the prospect of light.
In wireless EH communication systems, it have studied enter line number between the two node A and node B with EH abilities at present
According to the two-way cooperation transmission with energy, data or energy can be transmitted from node A to node B, while can also be from node B to section
Point A transmits data or energy.In cooperative communication network, existing research generally considers that source node and via node have EH energy
Power, source node transmits data or energy to via node, and energy can not be then transmitted between via node and destination node.But,
Current research is deep not enough, such as because via node is in addition to relaying the business from other nodes, it is also possible to have certainly
The business of body, then via node, which distributes how many bandwidth and energy, to be used to launch own service, and distribution how many bandwidth and energy are used
It is still the problem of needing to study and solve in forwarding service.
