Unlicensed spectrum is a spectrum that can be used for radio equipment communications divided by countries and regions. This spectrum is usually considered to be a shared spectrum, that is, communication devices in different communication systems as long as they meet the regulatory requirements set by the country or region on the spectrum. To use this spectrum, there is no need to apply for a proprietary spectrum authorization from the government.

In order to allow various communication systems that use unlicensed spectrum for wireless communication to coexist friendly on this spectrum, some countries or regions have stipulated the legal requirements that must be met when using unlicensed spectrum. For example, communication equipment follows the "listen before talk (LBT)" principle, that is, the communication equipment needs to perform channel detection before transmitting signals on channels of unlicensed spectrum. Only when the channel detection result is that the channel is idle, the communication device needs to perform channel detection. The communication device can only perform signal transmission; if the channel detection result of the communication device on the channel of the unlicensed spectrum is that the channel is busy, the communication device cannot perform signal transmission. In order to ensure fairness, in one transmission, the time that the communication device uses the channel of the unlicensed spectrum for signal transmission cannot exceed the maximum channel occupation time (Maximum Channel Occupancy Time, MCOT).

However, in the Rel-16NR system, due to the relaxation of the restriction conditions, the scenario where uplink resources occupy resources in the time domain is more relaxed, resulting in certain scenarios (for example, uplink resources occupy at least two time slots in the time domain). Part or all resources), there is no corresponding timer start or stop rule support, which is not conducive to the transmission of uplink resources.
