Abstract
In embodiments, an evolved Node B (eNB) of a wireless communication network may configure an enhanced physical downlink control channel (EPDCCH) physical resource block (PRB) set for a user equipment (UE). The EPDCCH-PRB set may include a plurality of PRB-pairs. The EPDCCH-PRB set may further include a plurality of enhanced resource element groups (EREGs) organized into localized enhanced control channel elements (ECCEs) having EREGs of the same PRB-pair and distributed ECCEs having EREGs of different PRB-pairs. In some embodiments, the eNB may determine a set of distributed EPDCCH candidates for the UE from the EPDCCH-PRB set, wherein the individual distributed EPDCCH candidates include one or more of the distributed ECCEs, and wherein the set of distributed EPDCCH candidates includes at least one EREG from each of the plurality of localized ECCEs. Other embodiments may be described and claimed.
