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 with a second UE, the method comprising:
- scrambling control information by a second UE ID, the control information including a first group ID and resource allocation information, the resource allocation information indicating an allocated resource including a frequency hopping pattern of the allocated resource;
transmitting the control information by a physical control channel from the first UE to the second UE; and
transmitting a physical shared channel, which is scrambled by the first group ID, in groupcast from the first UE to the second UE.

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.

5. A first user equipment (UE) for a device-to-device (D2D) communication with a second UE, the first UE comprising:
-
circuitry, which, in operation, scrambles control information by a second UE ID, the control information including a first group ID and resource allocation information, the resource allocation information indicating an allocated resource including a frequency hopping pattern of the allocated resource; and a transmitter, which is coupled to the circuitry and which, in operation, transmits the control information by a physical control channel from the first UE to the second UE, and transmits a physical shared channel, which is scrambled by the first group ID, in groupcast from the first UE to the second UE. - View Dependent Claims (6, 7, 8, 10)
