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.
Claims27
A wireless device comprising circuitry configured 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 second D2D communication group different from a first D2D communication group to which the wireless device belongs;
- and
- transmit the group identifier or an 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.
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;
- 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.
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.
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.
