1. A method, comprising:
activating a first bandwidth part in response to a first message in a case of switching from a second bandwidth part to the first bandwidth part, wherein the second bandwidth part is a bandwidth part that has been activated before a user equipment activates the first bandwidth part, wherein timing of a target timer is based on a unit time length of the second bandwidth part when the second bandwidth is activated;
in response to the first bandwidth part being activated, controlling the target timer to perform timing continuously based on the unit time length of the second bandwidth part until the target timer is stopped or the target timer expires, wherein the unit time length of the second bandwidth part is a slot length or a symbol length of the second bandwidth part; and
after the target timer is stopped or expires, controlling the target timer to perform timing based on a unit time length of the first bandwidth part, wherein:
the unit time length of the first bandwidth part is a slot length or a symbol length of the first bandwidth part, the target timer comprises a discontinuous reception (DRX)-retransmission timer or a DRX hybrid automatic repeat request-round-trip time (DRX HARQ RTT) timer, wherein, the unit time length of the first bandwidth part is greater than the unit time length of the second bandwidth part or the unit time length of the first bandwidth part is less than the unit time length of the second bandwidth part.
