The specification and drawings present a new method, apparatus and software related product (e.g., a computer readable memory) for discovery of D2D devices in wireless communications, e.g., LTE systems by relating beacon/discovery resources to paging frames, so that the UE may save power being active (e.g., in the wake-up state) only during paging frames. The user equipment may receive during a paging receiving time a paging signal from the wireless network and at least one discovery signal from at least one user equipment operating in the wireless network, wherein a discovery cycle period of the at least one discovery signal is different than the paging cycle period and is determined using the paging cycle period based on a predefined rule.
