Abstract
A method is disclosed for sending and receiving D2D subframes. The method may be applied in a system where a transmitting D2D-UE and one or more paired receiving D2D-UE(s) all belong to a single serving base station. The serving base station, which provides cell coverage for both the transmitting D2D-UE and the receiving D2D-UE(s), may be operated using FDD or TDD. The method may also be applied in a system where the transmitting D2D-UE and the receiving D2D-UE(s), respectively, belong to different servicing base stations. In this case, one base station provides cell coverage for the transmitting D2D-UE and another base station provides cell coverage for the receiving D2D-UE(s).
Claims14
In a wireless communications system including a first device-to-device (D2D) communications capable user equipment (D2D-UE) and a second D2D-UE, a communications method implemented in the first D2D-UE, the communications method comprising:
- transmitting, to the second D2D-UE, a D2D signal on a subframe.
A first device-to-device (D2D) communications capable user equipment (D2D-UE) used in a wireless communications system including the first D2D-UE and a second D2D-UE, the first D2D-UE comprising:
- a transmitter to transmit, to the second D2D-UE, a D2D signal on a subframe.
A communications method implemented in a wireless communications system including a first device-to-device (D2D) communications capable user equipment (D2D-UE) and a second D2D-UE, the communications method comprising:
- transmitting, from the first D2D-UE to the second D2D-UE, a D2D signal on a subframe.
A wireless communications system comprising:
- a first device-to-device (D2D) communications capable user equipment (D2D-UE);
- and
- a second D2D-UE,
- wherein the first D2D-UE transmits, to the second D2D-UE, a D2D signal on a subframe.
