First Claim
Patent Images
1. A method for operating a wireless device, the wireless device being enabled for device-to-device (D2D) operation, wherein the method comprises:
- entering, by the wireless device, an energy-saving mode;
monitoring, by the wireless device, a pre-defined channel for a D2D wake-up signal at pre-defined times during the energy-saving mode;
determining, by the wireless device, whether a received wake-up signal is intended for the wireless device; and
performing, by the wireless device, a wake-up procedure of a plurality of wake-up procedures for D2D communication,wherein said wake-up procedure is performed based on a selection of said wake-up procedure from the plurality of the wake-up procedures,wherein the plurality of wake-up procedures includes a network node assisted Proximity Services (ProSe) wake-up procedure and a non-network node assisted Proximity Services (ProSe) wake-up procedure,wherein said wake-up procedure is a function of plurality of factors according to a status of transmitting Tx UE, andwherein the plurality of factors comprises coverage status, Radio Resource Control (RRC) states, Traffic type and UE category.
