Abstract

Disclosed are a DCI format receiving method, a pre-configured downlink channel receiving method, a DCI format configuration method, a pre-configured downlink channel sending method and apparatus, a terminal device, and a network device. The DCI format receiving method at least includes: a terminal device being configured to detect a DCI format 2_0, wherein the terminal device does not expect a no slot format indicator field to be configured in the DCI format 2_0; or, if the terminal device determines that no slot format indicator field is configured in the DCI format 2_0, the terminal device not detecting the DCI format 2_0; or, if the terminal device determines that a slot format indicator field is configured in the DCI format 2_0, the terminal device detecting the DCI format 2_0.

Claims (10)

1. A method for receiving a Downlink Control Information (DCI) format, comprising:

in response to that a terminal device is configured to detect a DCI format 2_0 and the DCI format 2_0 is not configured with a slot format indicator field and a channel occupancy duration indicator field, detecting, by the terminal device, the DCI format 2_0; and

determining, by the terminal device after detecting the DCI format 2_0, a channel occupancy duration, the channel occupancy duration being a preset value configured by a network device.

2. A method for configuring a Downlink Control Information (DCI) format, comprising:

configuring, by a network device, a terminal device to detect a DCI format 2_0;

configuring, by the network device, no slot format indicator field and no channel occupancy duration indicator field in the DCI format 2_0 for the terminal device; and

configuring, by the network device, a first parameter for the terminal device, wherein the first parameter is used for the terminal device to determine a channel occupancy duration after detecting the DCI format 2_0.

3. A terminal device, comprising: a processor and a memory, wherein the memory is configured to store a computer program, and the processor is configured to execute the computer program stored in the memory to perform a method for receiving a Downlink Control Information (DCI) format, comprising:

in response to that the terminal device is configured to detect a DCI format 2_0 and the DCI format 2_0 is not configured with a slot format indicator field and a channel occupancy duration indicator field, detecting the DCI format 2_0; and

determining a channel occupancy duration after the terminal device detects the DCI format 2_0, the channel occupancy duration being a preset value configured by a network device.
