Abstract

An embodiment of the present invention provides a method for transmitting a physical uplink control channel PUCCH, including: determining the physical resource block occupied by multiple repeated transmissions of the short PUCCH according to the resource mapping method when the PUCCH is repeatedly transmitted; The short PUCCH is repeatedly transmitted multiple times. In this way, when the short PUCCH is repeatedly transmitted, the frequency diversity gain can be improved, and interference randomization can be performed. Further, the redundancy used by the short PUCCH repeated transmission in the short PUCCH repeated transmission is determined according to the pre-configured redundancy version sequence. version, thereby gaining incremental redundancy gains.

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 the time domain length is only one Orthogonal Frequency Division Multiplex...
