Abstract
In order to improve efficiency for sub-carrier allocation in a TDM multi-carrier system, the invention provides a novel frame structure and corresponding method and apparatus. During a centralized short period, each terminal sends a probe message including a predefined sequence to a network device and the network device estimates the channel characteristics for each sub-carrier with respect to each terminal by estimating the received probe message. In this way, sub-carrier allocation can be improved and sub-carriers with good channel characteristics are allocated to appropriate terminals.
