Embodiment approach

[0040] As an optional implementation manner, the first downlink control message includes:

[0041]Downlink Control Information (DCI) or Media Access Control Control Element (Media Access Control Control Element, MAC CE).

[0042] Wherein, the above-mentioned DCI may be that the DCI is an activation DCI for activating the SPS transmission, so that the DCI can not only activate the SPS transmission of the terminal, but also indicate the transmission period of the SPS transmission, thereby saving resource transmission overhead.

[0043] Of course, in the embodiment of the present invention, the above-mentioned DCI is not limited to the activation DCI, for example: it can also be other DCI, such as the reactivation or adjustment DCI sent to the SPS transmission that the terminal has activated, and the SPS transmission can be adjusted specifically through the DCI. transmission cycle.

[0044] In this implementation manner, the transmission cycle of the SPS can be indicated through...

Abstract

An embodiment of the present invention provides a semi-persistent scheduling transmission method, a terminal, and a network device. The method includes: receiving a first downlink control message, where the first downlink control message is at least used to indicate the transmission period of the SPS transmission; according to the The SPS transmission is performed in the transmission period. The embodiment of the present invention can improve the transmission performance of the terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a semi-persistent scheduling (Semi-Persistent Scheduling, SPS) transmission method, a terminal and a network device. Background technique [0002] In order to reduce the overhead of control signaling in the communication system, a Semi-Persistent Scheduling (Semi-Persistent Scheduling, SPS) transmission mode is introduced. In the current SPS transmission mode, the network pre-configures a set of parameters for the terminal, and each parameter item in this set of parameters includes only one parameter value, for example: including a transmission period, a Hybrid Automatic Repeat Request (HARQ ) number of processes, etc. During the transmission process, the terminal can only transmit according to the above-mentioned set of pre-configured parameters, so that the transmission performance of the terminal is relatively low. Contents of the invention [0003] Em...
