Patent ID: 7587176

Claim:
A mode switching method in a mobile communication system, the method comprising: providing a mode switching start point between an uplink signal and a downlink signal of a transceiver, wherein providing the mode switching start point comprises determining a mode switching time (MST) of the transceiver, determining a minimum guard period (GP min ) of the transceiver, and determining if the MST is greater than the GP min ; resetting the mode switching start point based on length of a guard period provided between the uplink signal and the downlink signal, wherein resetting the mode switching start point comprises determining an advancing time offset (Δt) based on the minimum guard period (GP min ), and setting the mode switching start point before a start point of the minimum guard period (GP min ) of the transceiver if the MST is greater than the GP min ; and starting mode switching at the mode switching start point.
