Method for performing bandwidth part switching by a user equipment

1. A method of performing Bandwidth Part (BWP) switching by a user equipment (UE), the method comprising:

scheduling to receive a Synchronization Signal Block (SSB) during a first period;

determining whether to perform the BWP switching based on the first period and a second period representing a time duration for performing the BWP switching; and

based on that the first period and the second period do not overlap, performing the BWP switching,

wherein a starting point of the BWP switching is earlier than a starting point of receiving the SSB by at least the second period.

2. The method of claim 1 , further comprising receiving, from a base station, a request for the BWP switching,

wherein the UE determines whether to perform the BWP switching based on the request.

3. The method of claim 1 , further comprising driving a timer for the BWP switching,

wherein the UE determines whether to perform the BWP switching based on the timer.

4. The method of claim 1 , wherein based on the first period and the second period overlapping, the BWP switching is not performed.

5. A user equipment (UE) configured to perform Bandwidth Part (BWP) switching, the UE comprising:

a transceiver; and

a processor configured to control the transceiver,

wherein the processor is further configured to:

schedule to receive a Synchronization Signal Block (SSB) during a first period;

determine whether to perform the BWP switching based on the first period and a second period representing a time duration for performing the BWP switching; and

perform the BWP switching based on that the first period and the second period do not overlap,

wherein a timing to start the BWP switching is earlier than a timing to start receiving the SSB by at least the second period.

6. The UE of claim 5 , wherein the processor is further configured to:

receive, from a base station through the transceiver, a request for the BWP switching, and

determine whether to perform the BWP switching based on the request.

7. The UE of claim 5 , wherein the processor is further configured to:

drive a timer for the BWP switching; and

determine whether to perform the BWP switching based on the timer.

8. The UE of claim 5 , wherein based on the first period and the second period overlapping, the BWP switching is not performed.

9. A processing apparatus configured to control a user equipment (UE) to perform Bandwidth Part (BWP) switching, the processing apparatus comprising:

at least one processor, and

at least one computer memory operably connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, perform operations comprising:

scheduling to receive a Synchronization Signal Block (SSB) during a first period;

determining whether to perform the BWP switching based on the first period and a second period representing a time duration for performing the BWP switching; and

performing the BWP switching based on that the first period and the second period do not overlap,

wherein a timing to start the BWP switching is earlier than a timing to start receiving the SSB by at least the second period.

10. The processing apparatus of claim 9 , wherein the operations further comprise:

receiving, from a base station, a request for the BWP switching, and

determining whether to perform the BWP switching based on the request.

11. The processing apparatus of claim 9 , wherein the operations further comprise:

driving a timer for the BWP switching; and

determining whether to perform the BWP switching based on the timer.

12. The processing apparatus of claim 9 , wherein based on the first period and the second period overlapping, the BWP switching is not performed.
