Embodiment Construction

[0094] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to specific embodiments and accompanying drawings.

[0095] Such as figure 1 As shown, the embodiment of the present invention provides a transmission method applied to a terminal, and the transmission method includes:

[0096] Step 101: Receive downlink control information DCI, the DCI includes N-bit indication information, the N-bit indication information is used to indicate whether the DCI triggers data transmission, and N is an integer greater than or equal to 1.

[0097] Preferably, N is 1, and the embodiment of the present invention indicates whether the DCI triggers data transmission through 1-bit indication information included in the DCI.

[0098] Specifically, when the 1-bit indication information is 0, it is used to indicate that the transmission of data is not triggered, and when the ...

Abstract

The invention provides a transmission method, a terminal and a base station, and solves the problem that a specific method for distinguishing whether downlink control information triggers transmissionof control information and data at the same time or only triggers transmission of the control information does not exist in a 5G system. The transmission method comprises the steps that downlink control information (DCI) is received, the DCI comprises N-bit indication information, the N-bit indication information is used for indicating whether the DCI triggers data transmission or not, and N is an integer larger than or equal to 1; And transmitting is performed according to the indication information in the DCI. According to the invention, whether the DCI triggers data transmission or not isindicated through the N-bit indication information contained in the DCI; Therefore, the transmission end can know whether the DCI triggers data transmission or not according to the indication information, and the problem that a specific method for distinguishing whether downlink control information triggers data transmission or not does not exist in a 5G system is solved.

Description

technical field [0001] The present invention relates to the technical field of communication applications, in particular to a transmission method, a terminal and a base station. Background technique [0002] In the long term evolution (Long Term Evolution, LTE) wireless communication system, aperiodic channel state information (Channel State Information, CSI) is transmitted through the Physical Uplink Shared Channel (Physical Uplink Shared Channel, PUSCH), and the eNodeB schedules the downlink control information of the uplink data (Downlink Control Information, DCI) triggers the UE to report aperiodic CSI. There is an information field in the downlink control information DCI for scheduling uplink data to trigger aperiodic CSI reporting. When the information field indicates that the UE needs to report aperiodic CSI, the UE reports aperiodic CSI through PUSCH at a predefined position. [0003] In the LTE system, control information (including hybrid automatic repeat request ...
