1. A laundry treating appliance for treating laundry items according to a cycle of operation, the laundry treating appliance comprising:
a chassis defining an interior;
a rotatable treating chamber located within the interior;
an antenna configured to repeatedly receive radio frequency identification (RFID) signal data from a set of RFID tags on the laundry items and outputting a signal indicative of the RFID signal data for each of the set of RFID tags, defining a set of RFID signal data; and
a controller configured to:
receive the set of RFID signal data during a rotation of the treating chamber;
determine a subset of the RFID signal data from the set of RFID signal data, the subset of RFID signal data defined by RFID signal data that varies repeatedly over time and representative of laundry items present within the treating chamber, wherein the varying of the RFID signal data indicates a rotating movement of the laundry items;
determine a subset of RFID tags from the set of RFID tags, the subset of RFID tags being associated with the subset of the RFID signal data; and
to at least one of: suggest, alter, or implement the cycle of operation based on the determined subset of RFID tags.
