[0030] Please refer to figure 1 , figure 1 It is a flow chart of the channel transmission method provided by the first embodiment of the present invention, including:
[0031] S101. Determine the transmission granularity used in channel transmission;
[0032] S102. Repeat the transmission channel based on the transmission granularity.
[0033] Optionally, the transmission granularity may include at least one of the following: an OFDM symbol, a short transmission time interval (sTTI), a search space, a time slot, a mini-slot, and a candidate set. Transmission granularity refers to the unit size of data repeatedly sent on the channel. Taking the OFDM symbol as the transmission granularity, it means that the repetition of data can reach the size of the OFDM symbol. Taking sTTI as the transmission granularity, it means that the repetition of data can reach the given level. The magnitude of the size of the sTTI. The size of the sTTI may be arbitrarily given, and generally it co...

[0102] This embodiment provides a method for repeatedly sending data whose transmission granularity is a short transmission interval sTTI.
[0103] The base station schedules the terminal to repeatedly transmit downlink data in multiple transmission time intervals (TTIs), using the sPDSCH channel. Optionally, the number of OFDM symbols included in the TTI is less, for example, no more than 7 OFDM symbols, but not limited to this. This embodiment is described with the short TTI structure in the LTE system, that is, the TTI is a short TTI (short TTI, sTTI for short), but it is not limited thereto. DL short TTI frame structure such as figure 2 As shown, 6 DL (Down Link) short TTIs are included in the 1ms subframe. When sPDSCH is configured to start from OFDM symbol #1 or #3, pattern 1 is used; when sPDSCH is configured to start from OFDM symbol #2 To start, use Pattern2. Note that the OFDM symbol numbering starts from 0, that is, there are 14 OFDM symbols in a 1ms subframe, a...

[0113] The base station schedules the terminal to repeatedly transmit downlink data with an OFDM symbol (abbreviated as OS, OFDM symbol) as the granularity in a single transmission time interval (TTI), and uses the sPDSCH channel. Optionally, the number of OFDM symbols included in the TTI is less, for example, no more than 7 OFDM symbols, but not limited to this. This embodiment is described with the short TTI structure in the LTE system, that is, the TTI is a short TTI (short TTI, sTTI for short), but it is not limited thereto. DL short TTI frame structure such as figure 2 As shown, 6 DL (Down Link) short TTIs are included in the 1ms subframe. When sPDSCH is configured to start from OFDM symbol #1 or #3, Pattern1 is used; when sPDSCH is configured to start from OFDM symbol #2 Initially, use Pattern2. Note that the OFDM symbol numbering starts from 0, that is, there are 14 OFDM symbols in a 1ms subframe, and the sequence numbers are #0 to #13.
