Methods for Resource Multiplexing of Distributed and Localized transmission in Enhanced Physical Downlink Control Channel
First Claim
1. A method comprising:
- receiving higher-layer information from a base station by a user equipment (UE) to determine a set of radio resources;
decoding a first set of candidate enhanced physical downlink control channels (ePDCCHs) within the set of received radio resources, wherein radio resources corresponding to each of the first set of ePDCCHs are defined by a first mapping rule; and
decoding a second set of candidate ePDCCHs within the same set of received radio resources, wherein radio resources corresponding to each of the second set of candidate ePDCCHs are defined by a second mapping rule.

Abstract
A method to multiplexing physical radio resources for both distributed and localized transmission of enhanced Physical Downlink Control Channel (ePDCCH) in a set of physical resource blocks (PRBs) is provided. A UE receives higher-layer information to determine a set of radio resources. The UE decodes a first set of candidate enhanced physical downlink control channel (ePDCCHs) within the set of received radio resources, wherein radio resources corresponding to each of the first set of ePDCCHs are defined by a first mapping rule (e.g., distributed-type ePDCCH). The UE decodes a second set of candidate ePDCCHs within the same set of received radio resources, wherein radio resources corresponding to each of the second set of candidate ePDCCHs are defined by a second mapping rule (e.g., localized-type ePDCCH). By multiplexing radio resources for distributed and localized ePDCCH transmission within the same set of PRBs, radio resource utilization is enhanced.

15. A method comprising:
-
transmitting higher-layer information indicative of a set of radio resources from a base station to a plurality of user equipment (UEs), wherein a first set of candidate enhanced physical downlink control channels (ePDCCHs) and a second set of ePDCCHs are allocated within the same set of radio resources; mapping physical radio resources in each of the first set of candidate ePDCCHs according to a first mapping rule; mapping physical radio resources in each of the second set of candidate ePDCCHs corresponds to a second mapping rule; and encoding downlink control information (DCI) over one or more candidate ePDCCHs to be transmitted to a UE if there is DCI intended for the UE. - View Dependent Claims (16, 17, 18, 19, 20)
