a first type of uplink transmission taking priority over a second type of uplink transmission, where the first type of uplink transmission is uplink transmissions for initiating establishment of an uplink connection, and the second type of uplink transmission is uplink transmissions other than the first type of uplink transmission in all uplink transmissions;
in order of uplink transmission priority of a primary cell and secondary cell(s);
an uplink control channel transmission taking priority over an uplink data channel transmission; and
in order of priority of data.
Optionally, the rule for prioritizing uplink signal transmissions is prescribed by a protocol or configured by a network-side device.
Optionally, when the second power control operation includes determining a transmit power corresponding to at least one second identification based on a maximum power reduction corresponding to the at least one second identification, an uplink transmit power reduction configuration is prescribed by a protocol or configured by a network-side device.
Optionally, the uplink transmit power reduction configuration includes at least one of the following:
-
- identification information of the at least one second identification; and
- a maximum power reduction corresponding to a radio access technology; and
- a maximum power reduction corresponding to the at least one second identification.
