Abstract
A base station and user devices exchange signaling and responsively exchange user data over BS2D traffic links. The base station and user devices exchange more signaling and responsively exchange user data directly between user devices over D2D traffic links. The base station system selects one of a plurality of D2D configurations based on system conditions and transfers D2D configuration instructions to the user devices. Some of the D2D configurations have one user device as a hub device and the other user devices as non-hub devices. The base station and the user devices exchange more signaling and responsively transfer user data and signaling using the selected D2D configuration in response to the D2D configuration instructions.
