Method and apparatus for performing inter-carrier D2D communication
First Claim
1. A method for performing a discovery transmission on a second carrier by a user equipment (UE) served by a primary cell (PCell) on a first carrier, comprising:
- determining at least one TX gap on the first carrier for the discovery transmission on the second carrier; and
transmitting, to a base station, a TX gap request including information on at least one uplink subframe on the first carrier corresponding to the at least one TX gap,wherein the at least one TX gap is determined based on an interruption time for retuning, synchronization delays, and subframe offset between the first carrier and the second carrier.

Abstract
A system and method for use in a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE) is disclosed. The method for performing a discovery transmission on a second carrier by a user equipment (UE) served by a primary cell (PCell) on a first carrier, includes receiving, from a base station, a signaling indicating that the UE read discovery resource configuration for the second carrier on the second carrier or that the UE should request the discovery resource configuration for the second carrier from the base station for acquiring the discovery resource configuration for the second carrier. The method also includes acquiring the discovery resource configuration based on the signaling.
