METHODS AND STATIONS FOR POWER SAVING IN RADIO COMMUNICATION

摘要

Methods and stations (200, 204) for enabling power saving in a receiving station (204) when a transmitting station (200) transmits a radio signal to a targeted station (202). The transmitting station (200) sets at least one power limitation bit that indicates an estimated power limitation status of the targeted station (202), and transmits the radio signal with a preamble including the power limitation bit. When receiving said preamble, the receiving station (204) is able to determine whether to receive and decode the remaining complete radio signal or not, based on the power limitation bit. For example, if the receiving station (204) itself is power limited, it can save power by not receiving and decoding the complete radio signal when the power limitation bit in the preamble indicates that the targeted station (202) is non-power limited.
