    摘要: Technology for channel state information (CSI) feedback in a multiple-input multiple-output (MIMO) communication system is disclosed. A method comprises receiving, at a mobile device, a dynamic channel state information (CSI) feedback switch signal from a transmission station that identifies a selected CSI feedback state for the mobile device. A process for selecting a precoding matrix indicator (PMI) and a rank indicator is identified based on the CSI feedback switch signal as either a process configured for MU-MIMO reception or single-user (SU) MIMO reception of a downlink signal at the mobile device.

    摘要: Embodiments of a system and method for beamforming in a Wireless Network are generally described herein. In some embodiments, an enhanced Node B (eNB) transmits to User Equipment (UE), from a plurality (Nc) of antenna ports of a plurality (Nt) of transmit antennas, a data signal where signal power is allocated in eigen beams, each of the Nt transmit antennas having antenna ports that are adjustable in elevation and in azimuth. The eNB also determines and transmits to the UE a Pc set of the largest principal eigen beams of the data signal and receives, as feedback from the UE, a precoding matrix that identifies the antenna port from which strongest energy in the data signal is detected at the UE. The eNB uses the precoding matrix for beamforming.
