Method and apparatus for scheduling PDSCHs of multiple subframes, base station, and user equipment

A communication method, comprising:

• receiving, in one subframe, a physical downlink control channel (PDCCH) sent by a base station, wherein the PDCCH is used to schedule transmission of physical downlink shared channels (PDSCHs) of at least two subframes of a user equipment, the PDCCH carries first indicator information, and the first indicator information indicates a channel resource for transmitting uplink acknowledgment/non-acknowledgment (ACK/NACK) information that is corresponding to the PDSCHs;
• and
• determining a transmission subframe carrying the uplink ACK/NACK information that is corresponding to the PDSCHs, and sending the uplink ACK/NACK information on the channel resource in the transmission subframe;
• wherein the PDCCH carries an ACK/NACK resource indicator (ARI) indicating a channel resource of uplink ACK/NACK information corresponding to at least one of the PDSCHs.

A base station, comprising:

• a channel sending unit, configured to send a physical downlink control channel (PDCCH) to a user equipment in one subframe, wherein the PDCCH is used to schedule transmission of physical downlink shared channels (PDSCHs) of at least two subframes of the user equipment, the PDCCH carries first indicator information, and the first indicator information indicates a channel resource for transmitting uplink acknowledgment/non-acknowledgment (ACK/NACK) information that is corresponding to the PDSCHs;
• and
• an information receiving unit, configured to determine a transmission subframe carrying the uplink ACK/NACK information that is corresponding to the PDSCHs, and receive the uplink ACK/NACK information on the channel resource in the transmission subframe;
• wherein a channel resource of uplink ACK/NACK information corresponding to a first PDSCH in the PDSCHs is indicated by an ACK/NACK resource indicator (ARI) in the PDCCH.

A user equipment, comprising:

• a channel receiving unit, configured to receive, in one subframe, a physical downlink control channel (PDCCH) sent by a base station, wherein the PDCCH is used to schedule transmission of physical downlink shared channels (PDSCHs) of at least two subframes of the user equipment, the PDCCH carries first indicator information, and the first indicator information indicates a channel resource for transmitting uplink acknowledgment/non-acknowledgment (ACK/NACK) information that is corresponding to the PDSCHs;
• and
• an information sending unit, configured to determine a transmission subframe carrying the uplink ACK/NACK information that is corresponding to the PDSCHs, and send the uplink ACK/NACK information on the channel resource in the transmission subframe;
• wherein uplink ACK/NACK information corresponding to at least one of the PDSCHs is transmitted on a channel resource indicated by an ACK/NACK resource indicator (ARI) carried in the PDCCH.
