Abstract  Abstract

Frequency-priority mapping of control channel elements (CCEs) to avoid relay physical control format indicator channel (R-PDFICH), and tree-based relay resource allocation to minimize resource allocation map bits A method and an apparatus are provided. Un-downlink (DL) control signal, an Un DL acknowledgment (ACK) / negative acknowledgment (NACK), and / or an eNBs relay physical downlink control channel (R-PDCCH) A method and apparatus for mapping in the DL direction (e.g., Node-B (eNB) delegated by a relay node (RN)) is disclosed. This includes time / frequency mapping of the control signal to the resource block (RB) of the MBSFN single-frequency network (MBSFN) -requested sub-frame in the RN cell and an encoding procedure therefor. Also disclosed is a method and apparatus for optimizing signaling overhead by avoiding R-PCFICH and minimizing the bits required for resource allocation.
