1. A hybrid automatic repeat request (HARQ) feedback method, performed by a terminal, comprising:
receiving a power saving signal, wherein the power saving signal is configured to indicate the terminal to perform a power saving related action; and
performing HARQ feedback based on a receipt result of the power saving signal,
wherein the power saving related action comprises one of:
in response to a data scheduling requirement, detecting and receiving a physical downlink control channel (PDCCH) for data scheduling during corresponding active time of the terminal; or
in response to no data scheduling requirement, skipping detection and receipt of a PDCCH for data scheduling during corresponding active time of the terminal;
wherein the active time is specific time of the terminal for monitoring PDCCH;
wherein performing the HARQ feedback based on the receipt result of the power saving signal comprises one of the following:
sending an acknowledge (ACK) feedback message to a base station in response to successfully receiving the power saving signal, and sending a non-acknowledge (NACK) feedback message to the base station in response to failing to receive the power saving signal;
sending an acknowledge (ACK) feedback message to a base station in response to successfully receiving the power saving signal, and feeding back nothing to the base station in response to failing to receive the power saving signal;
and
feeding back nothing to a base station in response to successfully receiving the power saving signal, and sending a non-acknowledge (NACK) feedback message to the base station in response to failing to receive the power saving signal.
