1. A wireless device comprising:
- first circuitry to detect a group identifier in a wireless transmission from a second wireless device served by a second eNB, the group identifier representative of a second device-to-device (D2D) communication group to which the second wireless device belongs, the wireless transmission directed to a third wireless device that belongs to the second D2D communication group, the group identifier comprising data representative of an identifier of the second eNB, and the second D2D communication group different from a first D2D communication group to which the wireless device belongs; and
second circuitry to, in response to detection of the group identifier, transmit the group identifier or the identifier of the second eNB to a first eNB serving the wireless device to notify the first eNB of interference from the second D2D communication group.

Abstract
Systems and techniques for wireless device-to-device (D2D) communication are provided herein. A D2D group identifier may be included in wireless transmissions within D2D groups. D2D interference mitigation processes may be initiated when a D2D group identifier is detected by a wireless device outside the D2D group.

11. An eNB, comprising:
-
a first module for detecting, in a wireless transmission from a first wireless communications device belonging to a first device-to-device (D2D) communication group, an identifier of a second D2D communication group to which a second wireless communications device belongs or an identifier of a second eNB serving the second wireless communications device, wherein the wireless transmission is transmitted to the eNB by the first wireless communications device in response to detection by the first wireless communications device of a wireless transmission between two members of the second D2D communication group, the wireless transmission between the two members of the second D2D communication group includes the identifier of the second D2D communication group, and the identifier of the second D2D communication group comprises data representative of an identifier of the second eNB; a second module for determining an identity of the second eNB based at least in part on the identifier; and a third module for initiating a D2D interference mitigation process with the identified second eNB. - View Dependent Claims (12, 13, 14, 15)

16. A device-to-device (D2D) communications device, comprising:
-
a first module for receiving, in a wireless transmission from an eNB serving the D2D communications device, an identifier of a D2D group to which the D2D communications device belongs, the identifier comprising data representative of an identifier of the eNB; and a second module for wirelessly transmitting the identifier of the D2D group in a control header of a wireless communication directed to another D2D communications device in the D2D group. - View Dependent Claims (17, 18, 19, 20, 21, 22)

23. At least one machine-accessible medium comprising instructions stored thereon that are configured to cause an eNB, in response to execution of the instructions by the eNB, to:
-
transmit, to a first wireless communications device belonging to a first device-to-device (D2D) communication group, an identifier of the first D2D group for inclusion in a control header of wireless communications transmitted by the first wireless communications device to other wireless communications devices belonging to the first D2D communication group; and transmit, to the first wireless communications device, a signal indicative of a format to be followed by the control header. - View Dependent Claims (24, 25, 26, 27)
