Title:
METHOD AND DEVICE FOR CONFIGURING SPATIAL DIVERSITY OF AN ENHANCED PHYSICAL DOWNLINK CONTROL CHANNEL
Document Type and Number:
WIPO Patent Application WO/2014/038877
Kind Code:
A1
Abstract:
A method for configuring spatial diversity of an enhanced Physical Downlink Control CHannel (ePDCCH) is provided. The method includes alternately using, by each Resource Element (RE) in an enhanced Resource Element Group (eREG), one of N
AP
Antenna Ports (AP) by granularity of one RE, mapping each RE in a Physical Resource Block (PRB) pair to a fixed AP. The present disclosure further discloses a method for constructing a localized enhanced Control Channel Element (eCCE) and a method for constructing a distributed eCCE. The present disclosure further discloses devices respectively corresponding to above-mentioned methods. By use of the present disclosure, performance of spatial diversity of a distributed ePDCCH is improved and a number of the REs in the localized eCCE and the distributed eCCE are averaged to guarantee that link performance is uniform or close to each other.
