  • Publication number: 20220361023
    Abstract: This application relates to a communication method and apparatus. A terminal device sends first uplink data to a network device. After sending the first uplink data, the terminal device monitors a first downlink control channel in a first search space in a first duration; and after the first duration ends, the terminal device monitors a second downlink control channel in a second search space in a second duration. A length of a periodicity of the second search space is greater than a length of a periodicity of the first search space. In this case, the terminal device monitors the second downlink control channel based on the second search space at a low frequency. Therefore, the second search space with a long periodicity is set, so that power consumption of monitoring the downlink control channel by the terminal device can be reduced.
