Wireless communication method for device to device communication and user equipment
First Claim
1. A wireless communication method performed by a first user equipment (UE) in a device-to-device (D2D) communication, the method comprising:
- scrambling first control information by a second UE ID, the first control information including a group ID and resource allocation information;
transmitting the first control information from the first UE to the second UE;
after scrambling the first control information, scrambling second control information by the group ID, the second control information including resource allocation information; and
transmitting the second control information from the first UE to the second UE,wherein the first and second control information includes bits used to indicate the resource allocation information including a frequency hopping pattern.

Abstract
Provided are wireless communication methods for D2D communication and UEs therefor. A wireless communication method involves transmitting either a first DCI or a second DCI based on whether a first UE and a second UE are to be in a communication type of groupcast or unicast. In the wireless communication methods, the first DCI and the second DCI are scrambled by the UE ID of the second UE if the first UE and the second UE are in the communication type of unicast upon transmitting the first DCI and the second DCI, and the first DCI and the second DCI are scrambled by the group ID if the first UE and the second UE are in the communication type of groupcast upon transmitting the first DCI and the second DCI.
