Mapping of enhanced physical downlink control channels in a wireless communication network
First Claim
1. An apparatus comprising:
- a communications module configured to communicate with a user equipment (UE) over a wireless communication network via a plurality of antenna ports;
a control module configured to generate an enhanced physical downlink control channel (ePDCCH); and
a mapping module coupled with the control module and the communications module and configured to;
map individual enhanced control channel elements (eCCEs) of a physical resource block (PRB) pair including a plurality of eCCEs to a plurality of non-continuous enhanced resource element groups (eREGs) of the PRB pair;
map the plurality of eREGs to individual antenna ports for transmission to the UE, wherein individual antenna ports are associated with a continuous group of eREGs; and
assign at least a portion of the ePDCCH to one or more of the eCCEs for transmission to the UE.

Abstract
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.

12. An apparatus comprising:
-
a communications module configured to communicate with user equipments (UEs) over a wireless communication network using a plurality of physical resource block (PRB) pairs, individual PRB pairs including a plurality of enhanced control channel elements (eCCEs); a control module configured to provide an enhanced physical downlink control channel (ePDCCH); and a mapping module configured to; map the eCCEs to a plurality distributed resource block (DRB) pairs to distribute the eCCEs of individual PRB pairs among the plurality of DRB pairs; and assign the ePDCCH to a first DRB pair of the plurality of DRB pairs for transmission to one or more of the UEs. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. One or more non-transitory computer readable media having instructions, stored thereon, that, when executed, cause a computing system to:
-
receive a distributed enhanced physical downlink control channel (ePDCCH) from an e Node B (eNB), the distributed ePDCCH including downlink control information (DCI) allocated to one or more enhanced control channel elements (eCCEs) of a first distributed resource block (DRB) pair, wherein the first DRB pair includes eCCEs mapped from a plurality of physical resource block (PRB) pairs; identify the ePDCCH as distributed rather than localized; and receive, based on the identification and resource block identifiers included in the DCI, a physical downlink shared channel (PDSCH) transmission in a second DRB pair. - View Dependent Claims (24, 25, 26, 27, 28, 29)
