Abstract
This application discloses a message sending method, a message receiving method, an apparatus, and a device. The message sending method includes: A network device sends, by using a physical downlink control channel PDCCH, DCI with s a cyclic redundancy check CRC bit, wherein the DCI is in a first DCI format or a second DCI format, wherein the DCI is used to indicate a terminal device to enter a sleep mode at a first moment. The network device receives a response message that is sent by the terminal device based on the DCI.
Claims20
A message sending method, wherein the method comprises:
- sending, by a network device by using a physical downlink control channel PDCCH, downlink control information DCI with a cyclic redundancy check CRC bit, wherein the DCI is in a first DCI format or a second DCI format, wherein the DCI is used to indicate a terminal device to enter a sleep mode at a first moment, the first DCI format is a DCI format used to indicate a scheduling of physical downlink shared channel PDSCH, and the second DCI format is a DCI format used to indicate a scheduling of physical uplink shared channel PUSCH;
- and
- receiving, by the network device, a response message that is sent by the terminal device based on the DCI.
A message receiving method, wherein the method comprises:
- detecting, by a terminal device, a physical downlink control channel PDCCH sent by a network device;
- if downlink control information DCI with a cyclic redundancy check CRC bit is found on the PDCCH through detection, entering, by the terminal device, a sleep mode at a first moment based on the DCI, wherein the DCI is in a first DCI format or a second DCI format, wherein the first DCI format is a DCI format used to indicate the scheduling of physical downlink shared channel PDSCH, and the second DCI format is a DCI format used to indicate the scheduling of physical uplink shared channel PUSCH;
- and
- sending, by the terminal device, a response message to the network device based on the DCI.
A communications apparatus, wherein the apparatus comprises:
- a transmitter, configured to send, by using a physical downlink control channel PDCCH, downlink control information DCI with a cyclic redundancy check CRC bit, wherein the DCI is in a first DCI format or a second DCI format, wherein the DCI is used to indicate a terminal device to enter a sleep mode at a first moment, the first DCI format is a DCI format used to indicate a scheduling of physical downlink shared channel PDSCH, and the second DCI format is a DCI format used to indicate a scheduling of physical uplink shared channel PUSCH;
- and
- a receiver, configured to receive a response message that is sent by the terminal device based on the DCI.
A communications apparatus, the apparatus comprises:
- a processor, configured to:
- detect a physical downlink control channel PDCCH sent by a network device;
- and if downlink control information DCI with a cyclic redundancy check CRC bit, wherein the DCI is in a first DCI format or a second DCI format is found on the PDCCH through detection, enter a sleep mode at a first moment based on the DCI, wherein the first DCI format is a DCI format used to indicate a scheduling of physical downlink shared channel PDSCH, and the second DCI format is a DCI format used to indicate a scheduling of physical uplink shared channel PUSCH;
- and
- a transmitter, configured to send a response message to the network device based on the DCI.
