[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: orthogonal frequency division multiplexing OFDM symbol, short transmission time interval sTTI (short Transmission Time Interval), search space, time slot, mini-slot, and candidate set. Transmission granularity refers to the unit size of data repeatedly sent on the channel. Taking OFDM symbol as the transmission granularity, it means that data can be repeated to the extent of OFDM symbol size. Taking sTTI as the transmission granularity, it means that data can be repeated to a given The magnitude of the sTTI. The size of the sTTI can be given arbitrari...

[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 thereto. This embodiment is described by using 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, use pattern Pattern1; when sPDSCH is configured to start from OFDM symbol #2 To start, use Pattern2. Note that the numbering of OFDM symbols here starts from 0, that is, there are 14 OFDM symbols in a ...

[0113] The base station schedules the terminal to repeatedly transmit downlink data at the granularity of OFDM symbol (referred to as OS, OFDM symbol) in a single transmission time interval (TTI), 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 thereto. This embodiment is described by using 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 numbering of OFDM symbols here starts from 0, that is, there are 14 OFDM symbols in a 1ms subframe, and the serial numbers are #0 to #13.

Abstract

The embodiment of the invention provides a channel transmission method and device, network equipment and a computer readable storage medium, the transmission granularity of channel transmission is determined and a channel is repeatedly transmitted based on the transmission granularity. Through the implementation of the embodiment of the invention, the repeated transmission of the channel is carried out after the transmission granularity of the channel transmission is determined, so that the possibility is provided for the transmission with smaller granularity, and the repeated transmission canbe realized by adopting a short transmission interval.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a channel transmission method and device, network equipment, and a computer-readable storage medium. Background technique [0002] Currently, the 4th generation mobile communication technology (4G, the 4th Generation mobile communication technology) long-term evolution (LTE, Long-Term Evolution) / advanced long-term evolution (LTE-Advance / LTE-A, Long-Term Evolution Advance) and the fifth generation mobile Communication technology (5G, the 5th Generation mobile communication technology) is facing more and more demands. Judging from the current development trend, both 4G and 5G systems are researching features that support enhanced mobile broadband, ultra-high reliability, ultra-low latency transmission, and massive connections. [0003] In order to support the characteristics of ultra-high reliability and ultra-low delay transmission, it is necessary to tran...
