DISCOVERY RESOURCE TIME-FREQUENCY JUMPING METHOD AND TERMINAL

摘要

Embodiments of the present invention disclose a discovery resource time-frequency hopping method and a terminal, where the terminal includes: a resource determining unit, configured to determine a real discovery resource in a real discovery resource pool; a frequency-domain expansion unit, configured to: perform frequency-domain virtual expansion on 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 determine a virtual discovery resource in a virtual discovery resource pool corresponding to the real discovery resource pool; a time-frequency hopping unit, configured to perform, according to a preset time-frequency hopping solution based on the virtual discovery resource pool or a time-frequency hopping solution that is based on the virtual discovery resource pool and that is broadcast by the base station, virtual time-frequency hopping on a correspondence of the determined virtual discovery resource in the virtual discovery resource pool; and a signal sending unit, configured to send a discovery signal by using a real discovery resource that corresponds to a virtual discovery resource which is occupied after the virtual time-frequency hopping. By means of the present invention, an advantage of combination can be maintained, and a probability of sending, by multiple terminals, discovery signals by unlimitedly using a same real discovery resource can be lowered.
