Abstract: A new carrier type (NCT) has been developed for LTE in order to reduce the overhead associated with cell-specific reference signals (CRS) and control signaling via the PDCCH. The NCT is an LTE carrier with minimized control channel overhead and cell-specific reference signals. Described herein are techniques where, upon receiving a PDSCH grant from a eNB using DCI format 1A to indicate a fallback transmission mode, a UE transmits a CQI to the eNB based upon CSI-RS resources contained in the NCT.

Abstract: 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.

Abstract: The present disclosure provides for the trigger of a beam refinement reference signal (BRRS) message. Triggering a BRRS message can include determining that a measured quality of a transmit and receive (Tx-Rx) beam pair is below the first value of the first quality threshold, the Tx-Rx beam pair corresponding to a current transmit (Tx) beam from an evolved node B (eNodeB) and the current receive (Rx) beam at the user equipment (UE), encoding a message for the eNodeB based on the determination that the quality of the Tx-Rx beam pair is below the quality threshold, wherein the message comprises a request for one or more BRRS, and processing the one or more BRRS to select a different Rx beam at the UE than the current Rx beam.
