    摘要： A method of channel estimation of a mobile communication system based on a time division pilot field is disclosed. The method uses a transmitting end that transmits a time division pilot sequence having a cyclic prefix and a receiving end that transforms the time division pilot sequence into frequency domain using a fast Fourier transform module. Channel estimation is performed to obtain a channel frequency response estimation result. The receiving end transforms the channel frequency response estimation result back into time domain and obtains a channel impulse response estimation result.

    摘要： A method for relaying and forwarding feedback information in hybrid automatic repeat request scenario is provided, wherein the method for sending feedback information includes that: a relay station receives a resource allocation message; the relay station determines the time of sending the feedback information according to the resource allocation message, and sends the corresponding feedback information when the feedback time arrives. The processes of triggering the relay station to perform feedback or sending in multiple HARQ scenarios such as initial transmission and retransmission of downlink and uplink, and uplink feedback loss of subordinate node etc. are integrally and uniformly defined according to the present invention.
