Abstract: A method for scheduling multiple users for multi-user full duplex communications in a wireless network over a wireless channel. The scheduling may be based on base station beam indices, base station channel measurements, received UE capabilities, received UE measured channel conditions and/or received UE positional information. In another embodiment, the scheduling of the UE full duplex time slots may be updated based on base station channel interference measurements, received UE measured channel interference, the received UE measured channel conditions, and/or received UE positional information updates.

Abstract: An apparatus in a user equipment node (UE) is configured to perform a method for channel feedback. The method includes determining, based on a common reference signal received from a base station and one or more channel conditions, a plurality of values for a receiver table. The method also includes determining a plurality of values for a decision table based on corresponding values in the receiver table and a predetermined interference table. The method further includes selecting a value from the decision table. In addition, the method includes transmitting, to the base station, at least one of a rank indicator (RI) value and a precoding matrix indicator (PMI) value associated with the selected value in the decision table.
