Method and Apparatus for D2D Transmission
First Claim
1. A method, comprising:
- determining, at a first user terminal capable of performing a direct device-to-device (D2D) communication with a second user terminal, whether to advance transmission in the D2D communication or not;
obtaining information indicating whether the second user terminal is advancing its transmission in the D2D communication or not; and
determining a structure for at least one communication interval in a D2D communication pattern at least partly based on the application of transmission timing advances at the first and second user terminals, wherein the D2D communication pattern comprises communication intervals allocated for communication for the first user terminal with respect to the second user terminal.

Abstract
There is provided a method comprising: determining, at a first user terminal capable of performing a direct device-to-device, D2D, communication with a second terminal, whether to advance transmission in the D2D communication or not; obtaining information indicating whether the second user terminal is advancing its transmission in the D2D communication or not; and determining a structure for at least one communication interval in a D2D communication pattern at least partly based on the application of transmission timing advances at the first and second user terminals, wherein the D2D communication pattern comprises communication intervals allocated for communication for the first user terminal with respect to the second user terminal.

15. An apparatus, comprising:
-
at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured to, with the at least one processor, cause the apparatus at least to; determine whether or not to advance transmission in a direct device-to-device (D2D) communication of a first user terminal capable of performing the D2D communication with a second user terminal; obtain information indicating whether the second user terminal is advancing its transmission in the D2D communication or not; and determine a structure for at least one communication interval in a D2D communication pattern at least partly based on the application of transmission timing advances at the first and second user terminals, wherein the D2D communication pattern comprises communication intervals allocated for communication for the first user terminal with respect to the second user terminal. - View Dependent Claims (16, 17, 18, 19, 24, 26, 28)

30. A computer readable memory tangibly storing a computer program that is readable by a computer and comprising program instructions which, when loaded into a first user terminal capable of performing a direct device to device (D2D) communication with a second user terminal, causes the first user terminal to:
-
determine whether or not to advance transmission by the first user terminal in the D2D communication; obtain information indicating whether or not the second user terminal is advancing its transmission in the D2D communication; and determine a structure for at least one communication interval in a D2D communication pattern based at least partly on the application of transmission timing advances at the first and second user terminals, wherein the D2D communication pattern comprises communication intervals allocated for communication for the first user terminal with respect to the second user terminal.
