In one implementation, a user equipment (“UE”) communicates D2D with another UE using uplink radio resources. The first UE receives a downlink signal from a base station and determines the reception time. The first UE also receives a timing advance for uplink communication. Based on the reception time and the timing advance, the first UE determines an uplink transmission time. When transmitting to the second UE, however, the first UE does not transmit at the determined UL transmission time. Rather, the first UE delays its D2D transmission for a period of time that is based on the second UE's uplink timing advance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods and device for performing device-to-device communication","description":"Disclosed are methods for carrying out device-to-device (“D2D”) communication.
