Method for beam switching in mmWave systems

A method for a user equipment (UE) system performing wireless communications at millimeter wavelength (mmWave) frequencies, comprising:

• determining a modified candidate value of a beam switching parameter based at least on operations at an mmWave frequency of the mmWave frequencies;
• and
• transmitting the modified candidate value of the beam switching parameter to a base station (BS);
• receiving a first control resource set (CORESET) on a first beam and a second CORESET on a second beam, wherein a beam switching gap (BSG) occurs between the first CORESET and the second CORESET;
• and
• performing beam switching within the BSG from the first beam to the second beam based at least on the beam switching parameter.

A base station (BS) system comprising:

• a transceiver configured to operate in millimeter wavelength (mmWave) frequencies;
• and
• a processor coupled to the transceiver, configured to:
• receive via the transceiver, a beam switching gap (BSG) capability corresponding to a user equipment (UE) including a modified candidate value of a beam switching parameter based at least on operations at an mmWave frequency of the mmWave frequencies;
• in response to the reception, transmit via the transceiver, a first transmission configuration indicator (TCI) state for the UE to receive a first beam;
• and
• transmit via the transceiver, a first control resource set (CORESET) on the first beam and a second CORESET on a second beam, wherein a BSG occurs between the first CORESET and the second CORESET, wherein the first CORESET identifies a second TCI state for the UE to receive the second beam.
