Terminal Uplink Control Information Transmission Optimization

The patent segments the repeated transmission of uplink control information into multiple distinct subframes, with each subframe containing a PUCCH transmission. By dividing the transmission process across time (multiple subframes) and applying different configurations (first configuration information for initial subframe, second configuration information for other subframes), the system achieves reliable communication while managing complexity through structured segmentation rather than unmanaged repetition.

The patent applies preliminary action by transmitting HARQ-ACK information in the initial subframe before subsequent retransmissions. This ensures that critical acknowledgment information is sent as early as possible, allowing the base station to begin processing feedback while still permitting additional transmissions in later subframes if needed. The first configuration information specifically enables this early transmission of complete information.

The patent applies local quality by using different configuration information for different subframes based on their specific roles. The initial subframe uses first configuration information optimized for starting the repeated transmission sequence (including HARQ-ACK capability), while other subframes use second configuration information optimized for continuation transmissions. This localized optimization improves overall transmission efficiency while maintaining manageable complexity through clear differentiation of subframe purposes.
