Method and device for using spectrum resources between LSA primary and secondary systems

The invention discloses a method for allocating spectrum resources between LSA primary and secondary users. The method comprises the steps that an LSA primary system device and an LSA secondary system device perform negotiation on spectrum resource allocation parameters, wherein the parameters include a geographic area range, a spectrum resource range and a time range; the LSA primary system device and the LSA secondary system device uses the spectrum resources according to the parameters.
