UE capabilities for supporting complementary bandwidth part operations in wireless communication

A method of wireless communication at a user equipment (UE), comprising:

• receiving, from a scheduling entity, a UE capability enquiry message;
• transmitting, to the scheduling entity, a UE capability information message in response to the UE capability enquiry message, the UE capability information message comprising bandwidth part (BWP) information of the UE, the BWP information indicating that the UE is capable of using a complementary BWP with a predetermined constraint;
• and
• communicating with the scheduling entity using an anchor BWP and the complementary BWP based on the BWP information,
• a first switching time between the anchor BWP and the complementary BWP being shorter than a second switching time between the anchor BWP and a non-complementary BWP.

A scheduling entity for wireless communication, comprising:

• a transceiver configured to communicate with a user equipment (UE);
• a memory;
• and
• one or more processors coupled with the transceiver and the memory,
• the one or more processors being configured to:
• transmit, to the UE, a UE capability enquiry message;
• receive, from the UE, a UE capability information message comprising bandwidth part (BWP) information that indicates a capability of the UE to utilize an anchor BWP and a complementary BWP to communicate with the scheduling entity, the BWP information indicating that the UE is capable of using the complementary BWP with a predetermined constraint, wherein a first switching time between the anchor BWP and the complementary BWP is shorter than a second switching time between the anchor BWP and a non-complementary BWP;
• and
• communicate with the UE using the anchor BWP and the complementary BWP based on the BWP information.
