Uplink Channel Transmission Flexibility via LBT Detection

The patent applies dynamics by enabling the terminal device to dynamically determine whether to perform repeated transmissions on continuous PUSCHs based on LBT detection results. Instead of static configuration, the system adapts the transmission strategy in real-time: if LBT succeeds on the first PUSCH, no repeated transmission is needed; if LBT fails, repeated transmission is performed. This dynamic adjustment resolves the contradiction by sacrificing implementation simplicity to gain flexibility in channel transmission.

The patent implements feedback by using LBT detection results to control whether repeated transmissions are performed. The terminal device detects the channel status before each PUSCH transmission and adjusts its behavior accordingly. This feedback mechanism ensures reliability only when necessary (when LBT fails initially), rather than always performing repeated transmissions, thus improving channel utilization efficiency while maintaining transmission reliability when needed.

The patent applies partial action by performing LBT only when necessary - specifically, when the terminal device needs to determine whether to perform repeated transmissions. The system does not require LBT before every single PUSCH transmission, but rather uses LBT results to make a decision about the transmission strategy. This selective approach maintains channel access reliability while reducing overall transmission complexity compared to performing LBT before every transmission.
