Incremental pilot insertion for channel and interference estimation

摘要

A method of generating a signal in a wireless communication device having dynamically allocated channel estimation resources, the method comprising assigning a baseline level of resources for channel estimation, wherein the baseline level of resources comprising a common pilot signal; determining a receiver signal quality metric greater than a predetermined threshold; determining resources to be omitted from the baseline level of resources; and generating a signal based in part on the baseline level of resources having data symbols allocated to the resources omitted from the baseline level of resources after determining by a receiver that one or more data symbols were unsuccessfully demodulated at the receiver using the baseline level of resources, wherein a dedicated pilot signal is punctured onto the one or more data symbols as well as a corresponding apparatus.
