Abstract

Methods and apparatuses for CSI reporting mechanisms are provided. A piece of user equipment (UE) includes a transceiver and a processor operably connected to the transceiver. The transceiver is configured to receive channel state information (CSI) process configuration information including at least one beamformed type associated with a plurality of non-zero-power (NZP) CSI reference signal (CSI-RS) resource configurations and receive a CSI-RS resource index (CRI) reporting configuration. The processor is configured to calculate, in response to receipt of the configuration information, a CRIand a channel quality indicator (CQI). The transceiver is further configured to report the CRI and the CQI by transmitting the CRI and the CQI on an uplink channel.

Description

technical field [0001] The present disclosure generally relates to channel state information (CSI) reporting for multiple transmit antennas including two-dimensional arrays. Such two-dimensional arrays may be associated with the type of multiple-input multiple-output (MIMO) system commonly referred to as "full-dimensional" MIMO (FD-MIMO) or massive-MIMO or 3D-MIMO. The present disclosure also relates generally to downlink synchronization for narrowband communication systems. Background technique [0002] Wireless communication has been one of the most successful innovations in modern history. Demand for wireless data services is growing rapidly due to the increasing consumer and business adoption of smartphones and other mobile data devices such as tablets, "notebook" computers, netbooks, e-book readers and machine-type devices . To meet the rapid growth of mobile data traffic and support new applications and deployments, improvements in radio interface efficiency and cov...
