Signal monitoring method and apparatus

A network device, comprising:

• at least one processor;
• and
• a memory coupled to the at least one processor and configured to store programming instructions that, when executed by the at least one processor, cause the network device to:
• determine a second signal, where the second signal is a first type of signal, and the first type of signal is a downlink control information (DCI) and the first type of signal indicates power consumption reduction information, and wherein there is a mapping relationship between bit value in the first type of signal and the power consumption reduction information;
• wherein the power consumption reduction information indicates the following:
• that a terminal device does not monitor a second type of signal in a first time resource length, wherein the second type of signal is a signal that indicates data scheduling, and the terminal device does not monitor the second type of signal in the first time resource length comprises:
• that the terminal device does not monitor the second type of signal in a first search space in the first time resource length, and that the terminal device monitors the second type of signal in a second search space in the first time resource length;
• and
• send a second signal in a downlink signal to a terminal device.

A non-transitory computer readable storage medium, wherein the computer readable storage medium stores a computer program, and when the computer program is run, cause a device to:

• detect a second signal in a downlink signal, where the second signal is a first type of signal, and the first type of signal is a downlink control information (DCI) and the first type of signal indicates power consumption reduction information;
• and
• determine, based on the second signal and a mapping relationship between at least one bit value in the first type of signal and at least one meaning of the power consumption reduction information, that the power consumption reduction information indicated by the second signal indicates the following:
• that the device does not monitor a second type of signal in a first time resource length, wherein the second type of signal is a signal that indicates data scheduling, and that the device does not monitor the second type of signal in the first time resource length comprises:
• that the device does not monitor the second type of signal in a first search space in the first time resource length, and that the device monitors the second type of signal in a second search space in the first time resource length.
