Method for node used for wireless communication and apparatus

A second node, comprising:

• at least one processor;
• and
• one or more non-transitory computer-readable storage media coupled to the at least one processor and storing programming instructions for execution by the at least one processor, wherein the programming instructions, when executed, cause the second node to perform operations comprising:
• receiving at least one uplink transmission, wherein the at least one uplink transmission is transmitted on a first transmission occasion;
• wherein each of the at least one uplink transmission is one of a plurality of candidate transmissions;
• a power of each of the at least one uplink transmission is allocated according to a priority of the respective uplink transmission in a first priority order;
• the plurality of candidate transmissions comprise a first physical random access channel (PRACH) transmission that comprises a plurality of repeatedly transmitted preambles over a plurality of PRACH occasions, wherein each of the plurality of repeatedly transmitted preambles corresponds to a different PRACH occasion in the plurality of PRACH occasions, and the first PRACH transmission belongs to one of a plurality of PRACH transmission groups;
• wherein the plurality of PRACH transmission groups include a first PRACH transmission group, a second PRACH transmission group, and a third PRACH transmission group that each corresponds to a different priority;
• and
• wherein the operations comprise:
• transmitting first configuration signaling, wherein the first configuration signaling indicates a plurality of candidate orders, and the first priority order is one of the plurality of candidate orders;
• and the PRACH transmission group to which the first PRACH transmission belongs is used to determine the first priority order from the plurality of candidate orders.
