Claim 0:
1. A method for transmitting positive acknowledgement (ACK)/negative acknowledgement (NACK) (ACK/NACK) information for data, comprising:
dividing, by a user equipment, a set of all available preamble sequences in a random access process into a plurality of sequence groups, wherein each sequence group of the plurality of sequence groups includes a plurality of preamble sequences, and wherein each preamble sequence in a same sequence group corresponds to a same processing capability level;
selecting, by the user equipment for the random access process, a preamble sequence from a sequence group of the plurality of sequence groups, wherein the sequence group corresponds to a processing capability level of the user equipment;
sending, by the user equipment to a base station, processing capability information of the user equipment by using the selected preamble sequence, wherein the processing capability information of the user equipment represents the processing capability level of the user equipment;
receiving, by the user equipment, a data packet from the base station;
receiving, by the user equipment, downlink control information (DCI) for the data packet from the base station, wherein the DCI comprises a field used to instruct a first delay to be used by the user equipment to send ACK/NACK information corresponding to the data packet, and wherein the first delay is associated with a scheduling requirement or a service priority corresponding to the data packet;
acquiring, by the user equipment, data information of the data packet;
computing, by the user equipment, a second delay by using the processing capability information of the user equipment and the data information of the data packet; and
determining, by the user equipment based on the first delay and the second delay, a subframe to send the ACK/NACK information corresponding to the data packet.
