1. An enhanced node B (eNB) operable to perform beamforming using multiple-input multiple-output (MIMO) in a cellular network, having computer circuitry configured to:
- configure one or more user equipment (UEs) to use a same or different multiple port (multi-port) channel state information reference signal (CSI-RS) pattern;
receive feedback reports from the one or more UEs associated with the multi-port CSI-RS pattern at the eNB;
construct a UE-specific or group UE-specific cell for the one or more UEs at the eNB using the feedback report from the one or more UEs; and
select a defined number of antennas associated with an antenna port based on the feedback report from the one or more UEs.

Abstract
A technology for an enhanced node B (eNB) that is operable to perform beamforming using multiple-input multiple-output (MIMO) in a cellular network. One or more user equipment (UEs) can be configured to use a same or different multiple port (multi-port) channel state information reference signal (CSI-RS) pattern. Feedback reports can be received from the one or more UEs associated with the multi-port CSI-RS pattern at the eNB. A UE-specific or more UEs at the eNB using the feedback report from the one or more UEs.

13. A user equipment (UE) operable to communicate in a multiple-input multiple-output (MIMO) cellular network, having computer circuitry configured to:
-
receive a multiple port (multi-port) channel state information reference signal (CSI-RS) pattern from an enhanced node B (eNB) at the UE, wherein the multi-port CSI-RS pattern is associated with multiple antenna ports; calculate a reference signal received power (RSRP) or a reference signal received quality (RSRQ) for each antenna port associated with the CSI-RS pattern; communicate a feedback report to the eNB, wherein the feedback report includes the RSRP or the RSRQ for each antenna port, and select a defined number of antennas associated with an antenna port based on the feedback report. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
