METHOD AND APPARATUS FOR UPLINK NETWORK MIMO IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. A method, comprising:
- receiving channel state information (CSI) reports from respective network nodes across which cooperative reception of respective transmissions from a user equipment unit (UE) is performed; and
computing a communication rate to be assigned to the UE for communication with the respective network nodes based at least in part on the CSI reports.

Abstract
Systems and methodologies are described herein that facilitate generation and processing of control signaling to support uplink network multiple-in-multiple-out (N-MIMO) communication in a wireless communication system. As described herein, respective network nodes associated with an uplink N-MIMO framework can generate channel state information (CSI) corresponding to an uplink channel from a designated network user to the respective nodes. Generated CSI can subsequently be communicated to an uplink anchor node for the network user in order to facilitate rate assignment, scheduling, and/or other operations with respect to the network user. As described herein, CSI generated and reported by respective cells can include channel profiles, carrier/interference profiles, estimated supported uplink rates, or the like. As additionally described herein, supplemental information such as observed interference levels, demodulation indicators, or the like can be communicated to an anchor node and utilized in rate assignment and/or scheduling.
