Cross-carrier scheduling with different cell numerologies

An apparatus for a user equipment (UE) configured for operation in a Fifth Generation New Radio (5G NR) and beyond wireless network, the apparatus comprising:

• processing circuitry, wherein to configure the UE for cross-carrier scheduling of data transmissions in the 5G NR and beyond wireless network, the processing circuitry is to:
• decode configuration signaling received from a base station, the configuration signaling indicating a first numerology parameter for a scheduling cell of the base station and a second numerology parameter for a scheduled cell of the base station;
• decode downlink control information (DCI) received via a physical downlink control channel (PDCCH) of the scheduling cell, the DCI scheduling a downlink (DL) data transmission in the scheduled cell of the base station;
• decode the DL data transmission received via a physical downlink shared channel (PDSCH) of the scheduled cell, when a difference between the first numerology parameter and the second numerology parameter is smaller than or equal to a pre-configured numerology threshold value;
• and
• refrain from decoding the DL data transmission when the difference between the first numerology parameter and the second numerology parameter is greater than the pre-configured numerology threshold value;
• and
• a memory coupled to the processing circuitry and configured to store the configuration signaling.

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a user equipment (UE), the instructions to configure the UE for cross-carrier scheduling of data transmissions in a Fifth Generation New Radio (5G NR) and beyond wireless network, and to cause the UE to perform operations comprising:

• decoding configuration signaling received from a base station, the configuration signaling indicating a first numerology parameter for a scheduling cell of the base station and a second numerology parameter for a scheduled cell of the base station;
• decoding downlink control information (DCI) received via a physical downlink control channel (PDCCH) of the scheduling cell, the DCI scheduling a downlink (DL) data transmission in the scheduled cell of the base station;
• decoding the DL data transmission received via a physical downlink shared channel (PDSCH) of the scheduled cell, when a difference between the first numerology parameter and the second numerology parameter is smaller than or equal to a pre-configured numerology threshold value;
• and
• refraining from decoding the DL data transmission when the difference between the first numerology parameter and the second numerology parameter is greater than the pre-configured numerology threshold value.

• encoding configuration signaling for transmission to a user equipment (UE), the configuration signaling indicating a first numerology parameter for a scheduling cell of the base station and a second numerology parameter for a scheduled cell of the base station;
• encoding downlink control information (DCI) for transmission via a physical downlink control channel (PDCCH) of the scheduling cell, the DCI scheduling a downlink (DL) data transmission in the scheduled cell of the base station;
• and
• encoding DL data for the DL data transmission via a physical downlink shared channel (PDSCH) of the scheduled cell, when a difference between the first numerology parameter and the second numerology parameter is smaller than or equal to a pre-configured numerology threshold value.
