Abstract: Provided are a hybrid automatic repeat request timing method and apparatus. The method comprises: in the case where a device detects physical shared channel transmission within a first target transmission time interval (TTI), the device transmitting an acknowledgement instruction (ACK) response or a negative acknowledgement instruction (NACK) response of a hybrid automatic repeat request (HARQ) of a corresponding physical shared channel within the (pre-set number)th TTI after a second target TTI, wherein the number of symbols L1 contained in a TTI for downlink data transmission and the number of symbols L2 contained in a TTI for uplink data transmission satisfy the following condition: LI∈{1, 2, 3, 4, 5, 6, 7}, I=1 or 2. According to the embodiments of the present invention, the problem in the relevant art that an HARQ timing relationship cannot satisfy the further shortening of a TTI length is solved.
