Apparatuses and methods for optimizing usage of a single interference cancellation and suppression receiver

A cellular station, comprising:

• a wireless transceiver, configured to perform wireless transmission and reception to and from a mobile communication device;
• and
• a controller, configured to not schedule simultaneous operations of both a Network-Assisted Interference Cancellation and Suppression (NAICS) and a Multi-User Superposition Transmission (MUST) in signaling information for the mobile communication device, and transmit the signaling information to the mobile communication device via the wireless transceiver.

A method for a cellular station to optimize usage of a single interference cancellation and suppression receiver in a mobile communication device, the method comprising:

• not scheduling simultaneous operations of both a Network-Assisted Interference Cancellation and Suppression (NAICS) and a Multi-User Superposition Transmission (MUST) in signaling information for a mobile communication device;
• and
• transmitting the signaling information to the mobile communication device.

A mobile communication device, comprising:

• a wireless transceiver, comprising a single interference cancellation or suppression receiver, configured to perform wireless transmission and reception to and from a cellular station;
• and
• a controller, configured to receive first signaling information of a Network-Assisted Interference Cancellation and Suppression (NAICS) operation and second signaling information of a Multi-User Superposition Transmission (MUST) operation from the cellular station via the wireless transceiver, and not perform the NAICS operation when the MUST operation is ongoing.

A method for a mobile communication device to optimize usage of a single interference cancellation and suppression receiver therein, the method comprising:

• receiving first signaling information of a Network-Assisted Interference Cancellation and Suppression (NAICS) operation and second signaling information of a Multi-User Superposition Transmission (MUST) operation from a cellular station;
• and
• not performing the NAICS operation when the MUST operation is ongoing.
