Abstract: A method and an apparatus for allocating ACKnowledgement (ACK)/Non-ACKnowledgement (NACK) channel resources and processing confirmation information are disclosed. The method includes: The network side determines one physical channel area among multiple physical channel areas to be used by an ACK/NACK channel, and notifies the determined physical channel area to a User Equipment (UE) so as to enable the UE to determine a channel for receiving or sending ACK/NACK information in the determined physical channel area according to a mapping rule. Moreover, the network side may send or receive ACK/NACK information on the physical channel area that includes the ACK/NACK channel. The method and apparatus improve the utilization ratio and flexibility of the ACK/NACK channel, and reduce the probability of conflict generated by the ACK/NACK channel.

The method further includes allocating, according to priorities of the first channel and the second channel, a first transmit power to the first subframe j and a second transmit power to the second subframe i. The first transmit power is less than or equal to a first power upper limit. A sum of the first transmit power and the second transmit power is less than or equal to a first threshold. A sum of third transmit power of the third subframe i+1 and the first power upper limit is less than or equal to a preset threshold.

Abstract: A sequence-based signal processing method and apparatus are provided. A sequence meeting a requirement for sending a signal by using a physical uplink control channel (PUCCH) is determined, where the sequence is a sequence {fn} consisting of N elements, fn is an element in the sequence {fn}, and the determined sequence {fn} is a sequence meeting a preset condition; then, the N elements in the sequence {fn} are respectively mapped to N subcarriers to generate a first signal; and the first signal is sent. By using the determined sequence, when a signal is sent by using a PUCCH, a low sequence correlation can be maintained, and a relatively small peak-to-average power ratio (PAPR) value and cubic metric (CM) value can also be maintained, thereby meeting a requirement of a communication application environment in which a signal is sent by using a PUCCH.
