1. A method for determining uplink control channel resources, comprising:determining, by a terminal, a quantity N of bits of uplink control information to be transmitted;
determining, by the terminal, a first quantity of physical resource blocks (PRBs) according to a target code rate and the N;
determining, by the terminal, a quantity of PRBs to be actually used according to the first quantity of PRBs and a quantity of preconfigured PRBs, wherein the quantity of the PRBs to be actually used is not greater than the quantity of the preconfigured PRBs; and
transmitting, by the terminal, uplink control information using the quantity of the PRBs to be actually used,
wherein the quantity of the preconfigured PRBs is determined by indicating through a higher layer signaling.
