MULTI-ACCESS SCHEME AND SIGNAL STRUCTURE FOR D2D COMMUNICATIONS

摘要

In embodiments, an evolved Node B (eNB) of a wireless communication network may map individual enhanced control channel elements (eCCEs) of a physical resource block (PRB) pair to a plurality of non-continuous enhanced resource element groups (eREGs) of the PRB pair. The eNB may further map the plurality of eREGs to individual antenna ports for transmission to the UE, with individual antenna ports associated with a continuous group of eREGs. The eNB may assign at least a portion of an enhanced physical downlink control channel (ePDCCH) to one or more of the eCCEs for transmission to the UE. Additionally, or alternatively, an eNB may map eCCEs of a plurality of PRB pairs to a plurality of distributed resource block (DRB) pairs.
