CHANNEL STATE INFORMATION AND ADAPTIVE MODULATION AND CODING DESIGN FOR LONG-TERM EVOLUTION MACHINE TYPE COMMUNICATIONS

摘要

A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE. The UE determines CSI. The UE determines whether to send the CSI based on at least one of a timer or a threshold. The UE sends the CSI upon determining to send the CSI. The UE may send the CSI in a MAC header upon determining to send the CSI. When the UE determines whether to send the CSI based on the threshold, the UE may determine whether to send the CSI based on a difference between the CSI and reference CSI. The UE may determine the reference CSI based on at least one of previously reported CSI, fixed CSI, or an MCS of a received data transmission from a base station. The UE may send CSI to the base station in an initial connection setup with the base station.
