Push-based relay selection for device-to-device communication

An apparatus for wireless communication, comprising:

• means for estimating a pathloss from each of a plurality of relay candidates to a first communication device to generate a first capacity estimate for the first communication device for each of the plurality of relay candidates;
• means for receiving at the first communication device, from a second communication device, a second capacity estimate for the second communication device for each of the plurality of relay candidates;
• and
• means for selecting a relay from the plurality of relay candidates for relaying communications between the first communication device and the second communication device based at least in part on each first capacity estimate for the first communication device and each second capacity estimate for the second communication device.

An apparatus for wireless communication, comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• instructions stored in the memory, the instructions being executable by the processor to:
• estimate a pathloss from each of a plurality of relay candidates to a first communication device to generate a first capacity estimate for the first communication device for each of the plurality of relay candidates;
• receive at the first communication device, from a second communication device, a second capacity estimate for the second communication device for each of the plurality of relay candidates;
• and
• select a relay from the plurality of relay candidates for relaying communications between the first communication device and the second communication device based at least in part on each first capacity estimate for the first communication device and each second capacity estimate for the second communication device.

A computer-readable medium for storing instructions executable by a processor, comprising:

• instructions to estimate a pathloss from each of a plurality of relay candidates to a first communication device to generate a first capacity estimate for the first communication device for each of the plurality of relay candidates;
• instructions to receive at the first communication device, from a second communication device, a second capacity estimate for the second communication device for each of the plurality of relay candidates;
• and
• instructions to select a relay from the plurality of relay candidates for relaying communications between the first communication device and the second communication device based at least in part on each first capacity estimate for the first communication device and each second capacity estimate for the second communication device.
