SYSTEMS AND METHODS FOR ADAPTIVE PILOT ALLOCATION

WIPO Patent Application WO/2016/192676

A1

System and method embodiments are provided for adaptive pilot allocation. In an embodiment, a method in a communication controller for adaptive pilot allocation includes determining at least one channel condition parameter for a wireless channel between the communications controller and a user equipment (UE). The method includes selecting a microframe pilot pattern to use for subsequent communications on the wireless channel according to the at least one channel condition parameter. Additionally, the method includes signaling an indication of the selected microframe pilot pattern to the user equipment. The method further includes transmitting data to the UE using the selected microframe pilot pattern.
