Method and apparatus for allocating resources and processing confirmation information
First Claim
1. A method, comprising:
- receiving, by a user equipment from a base station, a physical downlink control channel (PDCCH), wherein the PDCCH indicates a resource for carrying a physical downlink shared channel (PDSCH) on a downlink carrier of at least two downlink carriers and indicates one physical uplink control channel (PUCCH) area of at least two PUCCH areas for the PDSCH, at least one PUCCH area of the at least two PUCCH areas comprises at least two PUCCH resources, the at least two PUCCH areas comprises a first area and a second area, the one PUCCH area is dynamically being the first area or the second area, the first area is for carrying ACK/NACK information in a long term evolution (LTE) system, and the second area is for carrying ACK/NACK information in a LTE-A system compatible with the LTE system;
receiving, by the user equipment from the base station, the PDSCH on the downlink carrier of the at least two downlink carriers, wherein the at least two downlink carriers are capable of being configured to receive a downlink signal; and
transmitting, by the user equipment to the base station on a PUCCH resource in the one PUCCH area, acknowledgement or non-acknowledgement (ACK/NACK) in response to the PDSCH.

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.
