Abstract
An information transmission method and an apparatus, where the method includes: sending first indication information to a terminal, where the first indication information is used to indicate a format configuration of one or more time units in first time duration, where the format configuration is a time domain structure configuration of the one or more time units in a transmission direction, where the first time duration is not greater than second time duration, and where the second time duration is a maximum channel occupancy time of a network device.
Claims20
A method applied to a terminal and comprising:
- determining, based on a format configuration indicated by a network device and information about surroundings of the terminal, available time units in the format configuration;
- and
- sending, to the network device, an uplink control information (UCI) on a preset frequency domain resource in an unlicensed spectrum,
- wherein the preset frequency domain resource is configured by the network device via higher-layer signaling,
- wherein the UCI comprises second indication information of the available time units, and
- wherein the second indication information indicates to the network device to perform scheduling for data transmission.
A method applied to a network device and comprising:
- sending a first indication information to a terminal device, wherein the first indication information indicates a format configuration to be used by the terminal device for determining available time units in the format configuration;
- receiving an uplink control information (UCI) on a preset frequency domain resource in an unlicensed spectrum, wherein the preset frequency domain resource is configured by the network device via higher-layer signaling, wherein the UCI comprises second indication information of the available time units, wherein the second indication information indicates to the network device to perform scheduling for data transmission;
- and
- scheduling the data transmission based on the second indication information.
A communications apparatus, comprising:
- a processor;
- and
- a memory coupled to the processor and configured to store a computer execution instruction that, when executed by the processor, enable the communications apparatus to:
- determine, based on a format configuration indicated by a network device and information about surroundings of the communications apparatus, available time units in the format configuration;
- and
- send, to the network device, an uplink control information (UCI) on a preset frequency domain resource in an unlicensed spectrum,
- wherein the preset frequency domain resource is configured by the network device via higher-layer signaling,
- wherein the UCI comprises second indication information of the available time units, and
- wherein the second indication information indicates to the network device to perform scheduling for data transmission.
