Abstract
A method for channel transmission on an unlicensed spectrum, includes that: within the range of time of channel occupation by a first unlicensed carrier, channel sensing is performed on at least one second unlicensed carrier.
Claims18
A method for channel transmission on an unlicensed spectrum, applied to a network device, comprising:
- performing channel sensing on at least one second unlicensed carrier within a range of Channel Occupation Time (COT) of a first unlicensed carrier;
- and
- acquiring, within the range of the COT of the first unlicensed carrier, that a sensing result of a second unlicensed carrier is idle, then transmitting a downlink channel or a downlink signal via the second unlicensed carrier when the COT of the first unlicensed carrier ends.
A method for channel transmission on an unlicensed spectrum, applied to a terminal device, comprising:
- receiving a downlink channel or a downlink signal via an idle second unlicensed carrier of at least one second unlicensed carrier when Channel Occupation Time (COT) of a first unlicensed carrier ends.
A network device, comprising:
- a processor, configured to control a network interface to perform channel sensing on at least one second unlicensed carrier within a range of Channel Occupation Time (COT) of a first unlicensed carrier;
- and
- the network interface, configured to perform the channel sensing under the control of the processor,
- wherein the processor is configured to acquire, within the range of the COT of the first unlicensed carrier, that a sensing result of a second unlicensed carrier is idle, and control the network interface to transmit a downlink channel or a downlink signal via the second unlicensed carrier when the COT of the first unlicensed carrier ends.
1 more element
A terminal device, comprising:
- a network interface, configured to receive a downlink channel or a downlink signal via an idle second unlicensed carrier of at least one second unlicensed carrier when Channel Occupation Time (COT) of a first unlicensed carrier ends.
