Abstract
A system and method for providing both localized and distributed transmission modes for EPDCCH is disclosed, where one EPDCCH comprises of one or multiple CCEs. Localized versus distributed transmission may be defined in terms of the EPDCCH to CCE resource mapping. In a localized transmission CCEs are restricted to be contained within one PRB. In a distributed transmission a CCE spans over multiple PRBs. A UE can be configured to either receive the EPDCCH only in localized or only in distributed transmissions. A UE can also be configured to expect EPDCCH transmissions in both localized and distributed transmissions. In each PRB configured by the higher layer as an EPDCCH resource, 24 REs that may be used for any DMRS transmission are always reserved and not used for EPDCCH transmission.
