1. An unlicensed frequency band feedback method, comprising:
determining, by a network device, that a high-priority physical uplink shared channel is received; and
transmitting, by the network device, downlink feedback information to a terminal, wherein the downlink feedback information feeds back hybrid automatic repeat request acknowledgement information for the high-priority physical uplink shared channel;
wherein transmitting the downlink feedback information comprises:
transmitting the downlink feedback information at a first available downlink control information monitoring occasion after a time domain resource of ending position of the high-priority physical uplink shared channel, wherein the first available downlink control information monitoring occasion is one of a plurality of available downlink control information monitoring occasions, each available downlink control information monitoring occasion is a downlink control information monitoring occasion configured to monitor the downlink feedback information, and an interval between a time domain resource starting position corresponding to the first available downlink control information monitoring occasion and the time domain resource of the ending position of the high-priority physical uplink shared channel is greater than or equal to a first duration;
wherein the unlicensed frequency band feedback method further comprises:
receiving, by the network device, the high-priority physical uplink shared channel retransmitted, in response to the terminal not receiving the downlink feedback information in the first available downlink control information monitoring occasion or the first duration and the terminal being configured with a configured grant physical uplink shared channel, by the terminal through the configured grant physical uplink shared channel.
