Cross-carrier scheduling enhancements in new radio (NR)

An apparatus for wireless communications by a base station, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and executable by the processor to cause the apparatus to:
• apply a minimum scheduling delay when a subcarrier spacing (SCS) of a first component carrier is different than an SCS of a second component carrier;
• transmit, on the first component carrier, a first downlink control information (DCI) scheduling a first downlink data transmission on the second component carrier, the first DCI comprising a first slot offset associated with the first downlink data transmission;
• identify a timing of the first downlink data transmission on the second component carrier based at least in part on the first DCI, wherein the identified timing is at least the minimum scheduling delay after a timing of the first DCI transmitted on the first component carrier;
• and
• transmit the first downlink data transmission on the second component carrier during the identified timing of the first downlink data transmission in accordance with the first DCI.

A method of wireless communications by a user equipment (UE), comprising:

• applying a minimum scheduling delay when a subcarrier spacing (SCS) of a first component carrier is different than an SCS of a second component carrier;
• receiving, on the first component carrier, a first downlink control information (DCI) scheduling a first downlink data transmission on the second component carrier, the first DCI comprising a first slot offset associated with the first downlink data transmission;
• identifying a timing of the first downlink data transmission on the second component carrier based at least in part on the first DCI, wherein the identified timing is at least the minimum scheduling delay after a timing of the first DCI received on the first component carrier;
• and
• receiving the first downlink data transmission on the second component carrier during the identified timing of the first downlink data transmission in accordance with the first DCI.
