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.
Claims12
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
- if it is acquired, within the range of the COT of the first unlicensed carrier, that a sensing result of a second unlicensed carrier is idle, transmitting a downlink channel or a downlink signal via the second unlicensed carrier after an end of the COT of the first unlicensed carrier.
A method for channel transmission on an unlicensed spectrum, applied to a terminal device, comprising:
- in a case that a network device determines that a sensing result of a second unlicensed carrier is idle within a range of Channel Occupation Time (COT) of a first unlicensed carrier, receiving a downlink channel or a downlink signal via the second unlicensed carrier after an end of the COT of the first unlicensed carrier.
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:
- if it is acquired, within the range of COT of the first unlicensed carrier, that a sensing result of a second unlicensed carrier is idle, control the network interface to transmit a downlink channel or a downlink signal via the second unlicensed carrier after an end of the COT of the first unlicensed carrier.

A terminal device, comprising:
- a network interface, configured to:
- in a case that a network device determines that a sensing result of a second unlicensed carrier is idle within a range of Channel Occupation Time (COT) of a first unlicensed carrier, receive a downlink channel or a downlink signal via the second unlicensed carrier after an end of the COT of the first unlicensed carrier.
