Bandwidth part (BWP) switching delays for new radio (NR)

1. An apparatus comprising:

a memory to store a bandwidth part (BWP) configuration information for indicating a length of an interruption time for a BWP switch delay for a BWP switch, wherein the length of the interruption time is represented by a number of slots, and the interruption time does not occupy a symbol for a Demodulation Reference Signal (DMRS), wherein the BWP switch comprises changing a cyclic prefix based on a higher layer parameter; and

processing circuitry, coupled with the memory, to:

retrieve the BWP configuration information from the memory;

generate a message that includes the BWP configuration information; and

encode the message for transmission to a user equipment (UE).

2. The apparatus of claim 1 , wherein the message is to be transmitted via radio resource control (RRC) signaling.

3. The apparatus of claim 1 , wherein the number of slots for the BWP switch delay correspond to a largest subcarrier spacing (SCS) from a first SCS before BWP switching (SCS1) and a second SCS after BWP switching (SCS2).

4. The apparatus of claim 1 , wherein the BWP configuration information indicates a change of a center frequency of a BWP without a change of a bandwidth (BW) of the BWP.

5. The apparatus of claim 1 , wherein the BWP configuration information indicates a change of a BW of a BWP without a change of a center frequency of the BWP.

6. The apparatus of claim 1 , wherein the BWP configuration information indicates a change of a BW of a BWP and a center frequency of the BWP.

7. The apparatus of claim 1 , wherein the BWP configuration information indicates a change of subcarrier spacing (SCS).

8. The apparatus of claim 7 , wherein the BWP configuration information indicates that a center frequency of a BWP and a BW of the BWP is to remain unchanged.

9. One or more non-transitory, computer-readable media storing instructions, that, when executed by one or more processors, cause a user equipment (UE) to:

receive a message comprising bandwidth part (BWP) configuration information, the BWP configuration information indicating a length of an interruption time for a BWP switch delay for a BWP switch, wherein the length of the interruption time is represented by a number of slots, and the interruption time does not occupy a symbol for a Demodulation Reference Signal (DMRS), wherein the BWP switch comprises changing a cyclic prefix based on a higher layer parameter; and

perform the BWP switch based on the BWP configuration information.

10. The one or more non-transitory, computer-readable media of claim 9 , wherein the instructions are further to cause the UE to:

receive a downlink control information (DCI) command; and

perform the BWP switch based on the DCI command.

11. The one or more non-transitory, computer-readable media of claim 9 , wherein the BWP switch causes an interruption to one or more serving cells.

12. The one or more non-transitory, computer-readable media of claim 9 , wherein the BWP switch does not cause an interruption to one or more serving cells.

13. The one or more non-transitory, computer-readable media of claim 9 , wherein the BWP switch causes an interruption to a first serving cell in a first frequency range and does not cause an interruption to a second serving cell in a second frequency range.

14. The one or more non-transitory, computer-readable media of claim 13 , wherein the first frequency range (FR1) is 450 MHz to 6000 MHz, and wherein the second frequency range (FR2) is 24250 MHz to 52600 MHz.

15. One or more non-transitory, computer-readable media storing instructions, that, when executed by one or more processors, cause a base station to:

generate a first message comprising an initial bandwidth part (BWP) configuration;

encode the first message for transmission to a user equipment (UE);

generate a second message comprising BWP reconfiguration information, the BWP reconfiguration information for indicating a length of an interruption time for a BWP switch delay for a BWP switch, wherein the length of the interruption time is represented by a number of slots, and the interruption time does not occupy a symbol for a Demodulation Reference Signal (DMRS), wherein the BWP switch comprises changing a cyclic prefix based on a higher layer parameter; and

encode the second message for transmission to the UE.

16. The one or more non-transitory, computer-readable media of claim 15 , wherein the media further stores instructions for causing the base station to:

generate a DCI command message to initiate the BWP switch; and

encode the DCI command message for transmission to the UE.

17. The one or more non-transitory, computer-readable media of claim 15 , wherein the second message is to be transmitted via radio resource control (RRC) signaling.

18. The one or more non-transitory, computer-readable media of claim 15 , wherein the number of slots for the BWP switch delay correspond to a largest subcarrier spacing (SCS) from a first SCS before BWP switching (SCS1) and a second SCS after BWP switching (SCS2).

19. The one or more non-transitory, computer-readable media of claim 15 , wherein the BWP configuration information is to indicate a change of a BW of a BWP or a center frequency of the BWP.

20. The one or more non-transitory, computer-readable media of claim 15 , wherein the BWP configuration information is to indicate a change of subcarrier spacing (SCS).
