Abstract

The invention discloses a relay communication system utilizing regenerable energy power supply and an energy-saving mode. The relay communication system is characterized in that traditional power grid energy supplies power for a base station, regenerable energy collected by an energy collecting device supplies power for a relay, and the relay processes received signals and forward the received signals; in a downlink link, the relay periodically sends channel state information and current energy storage to the base station, and the base station determines to select a direct connection transmission mode or a relay transmission mode according to load information, information fed back by the relay and the channel conditions and conducts corresponding downlink resource distribution; in an uplink link, the relay periodically sends the state information of channels from a user to the relay and the current energy storage to the base station, the base station combines the information, the load information and state information, of channels from the relay to the base station and from a user to the base station, obtained by self-estimation to choose a direct connection transmission mode or a relay transmission mode, and conducts corresponding uplink link source distribution. By the adoption of the method, communication quality can be ensured, and non-renewable energy consumption can be saved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a relay communication system that uses renewable energy to supply power and saves energy consumption of network nodes powered by non-renewable energy in the system. Background technique [0002] With the development of wireless communication technology, users have higher and higher requirements for data transmission rate, which greatly limits the coverage of cellular cells; in addition, the rapid increase of communication equipment also makes the energy consumption of cellular systems increase. Adding a relay to a wireless communication system can reduce the impact of channel fading on data transmission, expand the coverage of the base station, and reduce the transmission power of the base station and mobile terminal while achieving the same transmission rate, thereby reducing energy consumption. However, considering the energy consumption of the relay ...
