Disclosed are a discovery resource time-frequency jumping method and a terminal. The terminal comprises: a resource determining unit, used for determining a real discovery resource in a real discovery resource pool; a frequency-domain expansion unit, used for performing frequency-domain virtual expansion of the real discovery resource pool according to a preset frequency division multiplexing factor value or a frequency division multiplexing factor value broadcast by a base station, and determining a virtual discovery resource in a virtual discovery resource pool corresponding to the real discovery resource pool; a time-frequency jumping unit, used for performing virtual time-frequency jumping of a correspondence of the determined virtual discovery resource in the virtual discovery resource pool according to a preset time-frequency jumping scheme or a time-frequency jumping scheme that is broadcast by the base station and is based on the virtual discovery resource pool; and a signal sending unit, used for sending a discovery signal by using a real discovery resource corresponding to the occupied virtual discovery resource on which virtual time-frequency jumping has been performed. By using the present invention, a combined advantage can be kept and the probability that multiple terminals send a signal by infinitely using a same real discovery resource can be reduced. |
