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.

Abstract: A sending method, a receiving method, a sending device, and a receiving device for signals in a multi-carrier system are provided. The sending method includes the following steps. Sequences are generated according to Cell-IDs used as parameters. The Cell-IDs satisfy predefined function corresponding relations between the Cell-IDs of multiple carriers in the same cell, and the predefined function corresponding relations include: corresponding relations between results obtained from rounding down quotients resulting from dividing the Cell-IDs of the carriers by N, where N is any integer greater than or equal to 0 and smaller than or equal to a maximum value of the Cell-IDs. Signals formed by the sequences or formed due to action of the sequences are sent. The methods and devices facilitate cell planning for the multi-carrier system, and avoid the uplink pilot interference between different cells.
