Method and apparatus for enabling channel and interference estimations in macro/RRH system

摘要

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.

1. A method of wireless communications, comprising:
signaling an identifier, to a user equipment (UE), indicating a first resource pattern for a first resource pattern group and a second resource pattern for a second resource pattern group to measure channel state conditions, wherein the first and second resource pattern groups each includes a first set of resources corresponding to a first reference signal pattern for channel estimation on which a first transmission point in a serving cell transmits channel state information reference signals (CSI-RSs) and a second set of resources corresponding to a second reference signal pattern for interference estimation on which a second transmission point in the serving cell transmits the CSI-RSs and on which the first transmission point in the serving cell does not transmit the CSI-RSs; receiving at least one channel state condition report from the UE based, at least in part, on measurements obtained based on at least one of the first resource pattern or the second resource pattern; and determining one or more resources for use by the UE based on the at least one received channel state condition report.
