METHOD FOR SWITCHING BANDWIDTH PARTS, TERMINAL DEVICE AND COMPUTER DATA CARRIER Russian patent published in 2022 - IPC H04W52/02 H04W72/04 H04W76/28 

FIELD: communication.

SUBSTANCE: invention relates to means for switching bandwidth parts. If a timer runs out, it is determined to switch from the active first bandwidth part (hereinafter – BWP) to the second BWP, wherein the active first BWP is not the second BWP. It is determined, based on a state of discontinuous receiving (hereinafter – DRX) of a terminal device and a long DRX cycle, whether the timer should be activated. Moreover, when determining, based on DRX state of the terminal device and the long DRX cycle, whether the timer should be activated, it is determined that the timer should be activated, when the duration, during which DRX state of the terminal device is in the long DRX cycle, is more than the predetermined duration, or it is determined that the timer should be activated, when a number of long DRX cycles, in which DRX state of the terminal device is present, is more than the predetermined number. The timer is stopped, if the terminal device is no longer in the long DRX cycle before the timer runs out.

EFFECT: decrease in the transmission of control information on a network side.
