Abstract
Provided are D2D communication methods and D2D-enabled wireless devices. The D2D communication method performed by a D2D-enabled wireless device includes transmitting signals in D2D subframes with a randomization pattern. The randomization pattern is designed based on relative subframe positions in a virtual pure D2D subframe sequence composed of multiple D2D subframes in one or more radio frames. In another embodiment, the eNB scheduling based resource allocation and the D2D-enabled wireless device selection on its own based resource allocation share a same randomization pattern design.
Claims8
An integrated circuit comprising:
- circuitry, which, in operation, controls:
- configuring a plurality of subframe sequences each including a plurality of device-to-device (D2D) subframes for D2D communication, wherein lengths of the subframe sequences are determined depending on an applicable operational scenario;
- and
- determining a first set of transmission subframe(s) in one of the subframe sequences in a time domain according to a resource pattern selected from a plurality of resource patterns, wherein the resource patterns are respectively repeated in the subframe sequences;
- and
- transmission circuitry, which, in operation, controls transmission of a first signal in the first set of transmission subframe(s).
Dependencies are inferred from the claim text.
