Description

TECHNICAL FIELD The present disclosure relates to a field of communications, and more particularly, to a method, a terminal and an apparatus for determining a physical uplink control channel (PUCCH) resource. BACKGROUND Hybrid automatic repeat request (HARQ) technology is a universal feedback technique used in wireless communication systems. In HARQ technology, after receiving the physical downlink shared channel (PDSCH) of the downlink service data sent by a network device, a terminal may feed back acknowledgment (ACK) or non-acknowledgement (NACK) information of the PDSCH to assist the network device in determining whether to reschedule the downlink service data or to schedule new downlink service data to the user terminal. The ACK and NACK information are collectively referred to as hybrid automatic repeat request acknowledgment (HARQ-ACK) feedback information. In the related art, a physical uplink control channel (PUCCH) resource of the HARQ-ACK feedback information is configured for the terminal. The PUCCH resource configured for the terminal may be a PUCCH resource at a slot level or a PUCCH resource at a subslot level. If the terminal is configured with both the slot-level PUCCH resource and the subslot-level PUCCH resource, after the terminal receives the PDSCH of the downlink service data, what level of PUCCH resource should be used for the HARQ-ACK feedback information of the PDSCH is a problem that is to be solved.

SR priority (e.g. high or low priority) should be defined. Exact details can be left to WI, which should also take into account RAN2 decision.
