    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.

    Abstract: A method of transmitting a narrow-band orthogonal frequency division multiplexing signal, comprising: determining a spectrum resource of a narrow-band orthogonal frequency division multiplexing system in a bandwidth of a long-term evolution (LTE) system sharing the bandwidth with the narrow-band orthogonal frequency division multiplexing system according to a resource selection strategy; and transmitting the narrow-band orthogonal frequency division multiplexing signal on the determined spectrum resource of the narrow-band orthogonal frequency division multiplexing system. The solution enables transmission of a narrow-band orthogonal frequency division multiplexing signal in a bandwidth of an LTE system, thus facilitating signal detection and cost reduction of a terminal served by the barrow-band orthogonal frequency division multiplexing system, and also reducing interference between the LTE system and the narrow-band orthogonal frequency division multiplexing system.

    Abstract: The present invention provides a data transmission method and apparatus. The method includes: transmitting physical downlink channel data according to a first-type reference signal (RS) or a second-type RS or a third-type RS. The method of the present invention ensures a balance between data transmission performance and RS overheads for different NarrowBand-Internet Of Things (NB-IOT) physical downlink channel data, thereby resolving the problem in the related art of not knowing which RS is to be used to transmit NB-IOT physical channel data.
