Abstract

The embodiment of the invention provides a method for transmitting a physical uplink control channel PUCCH. The method comprises the following steps: determining a physical resource block occupied bymultiple times of repeated transmission of the PUCCH according to a resource mapping manner during the multiple times of repeated transmission of the PUCCH; and performing multiple times of repeated transmission of the short PUCCH according to the physical resource block. In this way, the frequency diversity gain can be improved during the multiple times of repeated transmission of the short PUCCH, and interference randomization is performed, and further, a redundancy version used by the repeated transmission of the short PUCCH in the multiple times of repeated transmission of the short PUCCHis determined according to a preset redundancy version sequence, thereby obtaining an incremental redundancy gain.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular to a method for sending a Physical Uplink Control Channel (Physical Uplink Control CHannel, PUCCH) and a user terminal. Background technique [0002] In long-term evolution (Long Term Evolution, LTE), when acknowledgment (Acknowledgment, ACK) / negative acknowledgment (Not-Acknowledgment, NACK) repetition (Repetition) Physical Uplink Control Channel (PhysicalUplink Control CHannel, PUCCH) is sent repeatedly, use The same frequency domain resource, the disadvantage of this method is that the frequency domain diversity gain cannot be fully utilized, and if the PUCCH of other user equipment (UE) also uses the same time-frequency resource to repeatedly send the PUCCH, the UE will always interference from other UEs. For a 1-symbol short PUCCH (short PUCCH) in New Radio (NR), since there is only one Orthogonal Frequency Division Multiplexing (OFDM) symb...
