Abstract
A radio communication method, a radio communication system and a wireless terminal by which low power consumption and the flexibility of a network can be realized. A base station and wireless terminals change an intermittent receive period and the preamble length of data on the basis of characteristics of the multihop radio network to carry out the intermittent receiving of data. Thus, a wireless terminal relaying data can receive the data reliably and a useless boot-up of a receiving part and standby time can be largely reduced to achieve low power consumption.
