Systems and/or methods for providing EPDCCH in a multiple carrier based and/or quasi-collated network
First Claim
1. A method for providing enhanced physical downlink control channel (ePDCCH) in a wireless communication system, the method comprising:
- deriving, at a wireless transmit and receive unit (WTRU), a set of aggregation levels for monitoring an ePDCCH resource based on a number of available resource elements (REs) in a physical resource block (PRB) pair configured for the ePDCCH resource, wherein the number of available REs is derived for a subframe;
deriving, at the WTRU, a subset of the set of aggregation levels for monitoring the ePDCCH resource based on a number of PRB pairs configured for the ePDCCH resource; and
monitoring, at the WTRU, the ePDCCH resource on the subframe using the subset of the set of aggregation levels.

Abstract
ePDCCH may be provided. For example, a WTRU may receive a configuration for monitoring an ePDCCH resource. Based on the configuration, the WTRU may be configured to monitor and may monitor the ePDCCH resource on a particular subframe. Additionally, a WTRU may derive an aggregation level for a subframe associated with an aggregation level number NAL. The WTRU may transmit or monitor an ePDCCH using the aggregation level associated with the NAL for the subframe. A WTRU may also receive a reference signal. The WTRU may then determine the type of reference signal received. The WTRU may perform a demodulation of the PDSCH or ePDCCH using a demodulation timing based on the determined type. The ePDCCH or PDSCH may also be monitored or received by identifying a demodulation reference timing implicitly based on a location of one or more ePDCCH resources where the WTRU may receive DCI.
