Title:
METHOD AND APPARATUS FOR ENABLING CHANNEL AND INTERFERENCE ESTIMATIONS IN MACRO/RRH SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/109037
Kind Code:
A3
Abstract:
Aspects disclosed herein relate to channel and interference estimations in a coordinated multi-point (CoMP) environment. In the disclosed aspects, an eNB may be equipped to signal an identifier indicating a plurality of resource patterns, each associated with a resource pattern group, and each including a first resource element pattern for channel estimation and a second resource element pattern for interference estimation. The UE may be equipped to receive the signaling and perform channel estimation based at least in part on the first resource element pattern, and interference estimation based at least in part on the second resource pattern generate at least one channel state report based on the channel and interference estimations, and transmit at least one channel state report to an eNB. The eNB may determine one or more resources for use by the UE based on the at least one received channel state report.
