Embodiment Construction
[0044] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0045] The idea of the present invention is: the mobile station measures the signal quality of the current cell and the adjacent cell in real time, and reports the measurement information; , notify the mobile station to enter the cross-cell handover mode; the mobile station establishes a link connection with the current cell and the selected adjacent handover cell at the same time, and simultaneously receives and combines the signals of the current cell and the adjacent handover cell; the mobile station Release the link connection with the cell whose signal quality cannot meet the call requirements, and restore the normal communication mode.
[0046] In order to enable the mobile station to achieve cross-cell soft handover, the OFDM symbols in the cell where the mobile station is currently located and in the adjacent handover cell are respectively classifie...
