Incremental pilot insertion for channel and interference estimation

摘要

An apparatus for dynamic allocation of resources for channel estimation, the apparatus comprising a channel quality module configured to determine a request for channel estimation resources in place of at least one data symbol; a resource allocation module in communication with a receiver and configured to determine a baseline resource level comprising a common pilot signal and a variable resource level, the variable resource level based at least in part on the request for channel estimation resources and wherein the variable resource level comprises a dedicated pilot signal which is code punctured onto a data symbol; and a receiver module configured to receive a request for variable channel resources after determining that one or more data symbols were unsuccessfully demodulated and a corresponding method.
