PILOT SHIFTING

摘要

Some example embodiments presented herein may be directed towards a method in a Base Station, which may be comprised in a Radio Network, for transmitting a combined wireless communication signal. The combined wireless communication signal may comprise a primary and a secondary signal component. The method may comprise transmitting the secondary signal component to be received by an user equipment, the secondary signal component may comprise secondary pilot resources that may be dynamically shifted, where the dynamic shifting may be based on a current estimation procedure. Some example embodiments presented herein may be directed towards a method in an user equipment, which may be comprised in a Radio Network, for estimating the combined communication channel. The method may comprise receiving from the Base Station the dynamically shifted combined wireless communication signal comprising primary and secondary signal components. The method may also comprise estimating the primary channel when the current estimation procedure is a primary channel estimation procedure, and estimating the secondary channel when the current estimation procedure is a secondary channel estimation procedure.
