What is claimed is:

1. A method for wireless communication at a user equipment (UE), comprising:

establishing a connection with a base station via at least a first component carrier (CC) and a second CC, wherein the first CC has a different numerology than the second CC;

receiving the downlink control channel transmission via the first CC;

receiving, responsive to the downlink control channel transmission, the reference signal transmission on the second CC based at least in part on the minimum gap; and

measuring one or more channel characteristics of the reference signal transmission.

2. The method of claim 1, wherein the resource associated with the downlink control channel transmission comprises an orthogonal frequency division multiplexing (OFDM) symbol of the downlink control channel transmission on the first CC, the resource associated with the reference signal transmission comprises an OFDM symbol of the reference signal transmission on the second CC, and the minimum gap is measured in OFDM symbols of a numerology of the second CC.

3. The method of claim 1, wherein the resource associated with the downlink control channel transmission comprises a first slot containing the downlink control channel transmission on the first CC, the resource associated with the reference signal transmission comprises a second slot containing the reference signal transmission on the second CC, and the minimum gap is measured as a number of slots of the second CC, wherein the minimum gap is identified based at least in part on a location of the downlink control channel transmission within the first slot.

4. The method of claim 1, further comprising:

transmitting an indication of the minimum gap to the base station.

5. The method of claim 4, wherein the minimum gap is measured with respect to a first or last orthogonal frequency division multiplexing (OFDM) symbol of the downlink control channel transmission relative to a first or last OFDM symbol of the reference signal transmission.

6. The method of claim 4, wherein the indication of the minimum gap is provided for a plurality of different combinations numerologies of the first CC and the second CC.

7. The method of claim 1, wherein the minimum gap is prespecified at the UE and the base station for each of a plurality of different numerology combinations.

8. The method of claim 7, wherein a same minimum gap is provided for each of the plurality of different numerology combinations.

9. The method of claim 1, wherein the minimum gap is further based at least in part on a beam switching gap of the UE.

10. The method of claim 9, wherein the minimum gap is determined as a sum of a minimum offset between the downlink control channel transmission and the reference signal transmission and the beam switching gap, or based on a maximum value of the minimum offset or the beam switching gap.

11. The method of claim 10, wherein the minimum offset is prespecified for each of a plurality of different numerology combinations.

12. The method of claim 11, wherein a same minimum offset is provided for each of the plurality of different numerology combinations.

13. The method of claim 1, wherein the minimum gap is identified when the second CC has a shorter resource duration than the first CC.

14. The method of claim 1, wherein the minimum gap is determined based at least in part on a duration of the downlink control channel transmission and a scaling factor, wherein the scaling factor is proportional to a difference in the numerologies of the first CC and the second CC.

15. The method of claim 1, wherein the minimum gap is provided for each frequency band combination configured for the connection with the base station, for each frequency band pair combination configured for the connection with the base station, or any combinations thereof.

16. The method of claim 1, wherein the UE transmits minimum gap information to the base station that indicates minimum gaps for two or more frequency band combinations configured for the connection with the base station, two or more frequency band pair combinations configured for the connection with the base station, one or more frequency band pair combination that is unsupported by the UE, or any combinations thereof.

17. A method for wireless communication at a base station, comprising: establishing a connection with a user equipment (UE) via at least a first component carrier (CC) and a second CC, wherein the first CC has a different numerology than the second CC;

identifying a minimum gap between a resource associated with a downlink control channel transmission on the first CC and a resource associated with a reference signal transmission on the second CC;

transmitting the downlink control channel transmission to the UE via the first

CC; and

transmitting, responsive to the downlink control channel transmission, the reference signal transmission to the UE on the second CC based at least in part on the minimum gap.
