Method and apparatus for allocating resources and processing confirmation information

An apparatus, comprising:

• a storage medium including executable instructions;
• and
• a processor;
• wherein the executable instructions, when executed by the processor, causes the apparatus to:
• transmit a physical downlink control channel (PDCCH) to a terminal device, 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 indicated as the first area or the second area, and the at least two downlink carriers are capable of being configured to transmit downlink signals for the terminal device;
• receive 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
• receive, on a PUCCH resource in the one PUCCH area, acknowledgement or non-acknowledgement (ACK/NACK) in response to the PDSCH.

A non-transitory computer-readable storage medium comprising instructions which, when executed by a base station, cause the base station to carry out the steps of:

• transmitting 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 indicated as the first area or the second area, and the at least two downlink carriers are capable of being configured to transmit downlink signals for a terminal device;
• transmitting the PDSCH on the downlink carrier;
• and
• receiving, on a PUCCH resource in the one PUCCH area, acknowledgement or non-acknowledgement (ACK/NACK) in response to the PDSCH.

• receiving the PDSCH on the downlink carrier of the at least two downlink carriers, wherein the at least two downlink carriers are configured for the terminal device and are capable of being configured to receive downlink signals;
• and
• transmitting, on a PUCCH resource in the one PUCCH area, acknowledgement or non-acknowledgement (ACK/NACK) in response to the PDSCH.
