Method and device for channel detection configuration of listen-before-talk mechanism on unlicensed spectrum

A device for a channel detection configuration of a listen-before-talk mechanism on an unlicensed spectrum, comprising:

• a processor;
• and
• a memory, coupled with the processor and configured to store program codes which, when executed by the processor, become operational with the processor to:
• compare a current cell load value with a preset cell load threshold value when there is data to be sent in a data buffer;
• calculate a priority of a current cell based on a channel occupation time required for transmitting the data to be sent, a duration proportion of which the current cell occupies a channel in a preset duration prior to transmitting the data to be sent, and an adjustment factor determined according to an occupation condition of current cell channel resources and a service quality requirement of the data to be sent, when the current cell load value is less than or equal to the preset cell load threshold value;
• compare the priority of the current cell with a preset priority threshold;
• and
• perform a channel detection with clear channel assessment (CCA) according to a channel detection parameter of a listen-before-talk mechanism when the priority of the current cell is greater than the preset priority threshold, and start to transmit the data when the channel detection with CCA is completed.

A non-transitory computer storage medium, configured to store programs which, when executed by a computer, are operable with the computer to:

• compare a current cell load value with a preset cell load threshold value when there is data to be sent in a data buffer;
• calculate a priority of a current cell based on a channel occupation time required for transmitting the data to be sent, a duration proportion of which the current cell occupies a channel in a preset duration prior to transmitting the data to be sent, and an adjustment factor determined according to an occupation condition of current cell channel resources and a service quality requirement of the data to be sent, when the current cell load value is less than or equal to the preset cell load threshold value;
• compare the priority of the current cell with a preset priority threshold;
• and
• perform a channel detection with clear channel assessment (CCA) according to a channel detection parameter of a listen-before-talk mechanism when the priority of the current cell is greater than the preset priority threshold, and start to transmit the data when the channel detection with CCA is completed.
