Abstract
A sending parameter of a preamble is compared with at least one preset parameter threshold to obtain a comparison result. A channel priority is determined in accordance with the comparison result. When a plurality of uplink channels are required for simultaneous transmission, the transmitting powers of the plurality of uplink channels is determined in accordance with the channel priority; and the plurality of uplink channels comprising a PRACH. This scheme adopts an unfixed strategy for the ranking of the PRACH in the channel priority, and determines the ranking of the PRACH in the channel priority by comparing the sending parameter of the preamble with a preset parameter threshold or receiving a signaling from a base station.
