1. A wireless communication system user equipment, comprising:
- a user equipment; and
a base station connected to a cellular communication network, the base station comprising a first wireless interface configured to broadcast information on resources allocated for a device-to-device (D2D) discovery signal transmission; and
control circuitry coupled to the first wireless interface, the control circuitry being configured to control the first wireless interface to transmit a message which indicates whether the user equipment is enabled to use the allocated resources for the D2D discovery signal transmission, the control circuitry further configured todetermine whether the user equipment is to be prioritized over other user equipment, and when the user equipment is to be prioritized over the other user equipment, generate a message that i) allocates resources to the user equipment that are different from type 1 D2D discovery resources, ii) allocates type 2 D2D discovery resources to the user equipment, or iii) disables the user equipment from using the type 1 D2D discovery resources, andwhen the user equipment is not to be prioritized over the other user equipment, determine a usage level of the type 1 D2D discovery resources, and when the usage level is below a threshold level generate a message that enables the user equipment to use a resource selected from a type 1 D2D discovery resource, and when the usage level is greater than the prescribed threshold level, generate a message that allocates a type 2 D2D discovery resource to the user equipment, or disables the user equipment from selecting a type 1 D2D discovery resource for the transmission of a D2D discovery signal and from using a type 2 discovery resource for the transmission of a D2D discovery signal;
the user equipment comprisinga second wireless interface configured for communication with the base station, the second wireless interface being configured to receive information on resources allocated for D2D discovery signal transmission; and
a processor coupled to the second wireless interface, the processor being configured todetermine whether a message received at the second wireless interface enables the user equipment to use the allocated resources; and
control the wireless interface to transmit a device-to-device discovery signal using the allocated resources depending on whether the message enables the user equipment to use the allocated resources.

Abstract
A user equipment receives information on allocated resources for a device-to-device discovery. An enabler signaling is performed in which the user equipment is operative to determine whether a message received at a wireless interface enables the user equipment to use the allocated resources.

10. A cellular communication network node, comprising:
-
a wireless interface configured to broadcast information on resources allocated for a device-to-device (D2D) discovery signal transmission, and control circuitry coupled to the wireless interface, the control circuitry being configured to determine whether a user equipment is to be enabled to use the allocated resources for the device-to-device discovery signal transmission, and control the wireless interface to transmit a message which indicates whether the user equipment is enabled to use the allocated resources for the device-to-device discovery signal transmission, where in performing the determination the control circuitry is configured to determine whether the user equipment is to be prioritized over other user equipment, and when the user equipment is to be prioritized over the other user equipment generate a message that i) allocates resources to the user equipment that are different from type 1 D2D discovery resources, ii) allocates type 2 D2D discovery resources to the user equipment, or iii) disables the user equipment from using the type 1 D2D discovery resources, and when the user equipment is not to be prioritized over the other user equipment, determine a usage level of the type 1 D2D discovery resources, and when the usage level is below a threshold level generate a message that enables the user equipment to use a resource selected from a type 1 D2D discovery resource, and when the usage level is greater than the prescribed threshold level generate a message that allocates a type 2 D2D discovery resource to the user equipment, or disables the user equipment from selecting a type 1 D2D discovery resource for the transmission of a D2D discovery signal and from using a type 2 discovery resource for the transmission of a D2D discovery signal. - View Dependent Claims (11, 12, 13, 14, 15, 16)
