1. A method for controlling a power ramping counter, applied to a terminal and comprising:
determining that a random access preamble is transmitted on one or more first carriers; and
in response to the random access preamble being transmitted on the one or more first carriers, controlling a count value of the power ramping counter according to whether the one or more first carriers change relative to one or more second carriers, wherein
the one or more second carriers are used for transmitting the preamble before the preamble is transmitted on the one or more first carriers; and
the controlling the count value of the power ramping counter according to whether the one or more first carriers change relative to the one or more second carriers comprises:
determining that a first preset condition is met; and
in response to the first preset condition being met, controlling the count value of the power ramping counter to be increased by 1, wherein the first preset condition comprises at least one of:
a type of the one or more first carriers used for transmitting the preamble is different from a type of the one or more second carriers used for transmitting the preamble;
a scanning sequence of the one or more first carriers used for transmitting the preamble is different from a scanning sequence of the one or more second carriers used for transmitting the preamble; or
a number of the first carriers used for transmitting the preamble is different from a number of the second carriers used for transmitting the preamble;
or
determining that a second preset condition is met; and
in response to the second preset condition being met, controlling the count value of a power ramping counter corresponding to the first carrier to be increased by 1, wherein the second preset condition comprises:
types of the second carrier and the first carrier that are respectively used when the preamble is transmitted at two continuous times are different.
