Abstract: A base station transmits energy related information to a mobile station, wherein the energy related information is related to at least one of an energy harvester module and an energy storage module coupled to the base station. The energy related information includes: an energy level and a maximum storage capacity of the energy storage module; an energy harvest rate and energy consumption rate. The base station and the mobile station perform energy trade off, where when the serving base station has an energy level below a threshold, the mobile station uses certain configuration to send information to the serving base station where the configuration can use more resources, such as RF chains, thereby increasing energy consumption of the mobile station while enabling the base station to conserve energy.
