Communication method, device, terminal, base station and storage medium

Abstract

Embodiments of the present invention provide a communication method and device, a terminal, a base station, and a storage medium. In view of the problem in the prior art that when each control information in the two-level control information cannot be received correctly, the two ends of the communication cannot normally perform data transmission, the present invention The communication method provided by the embodiment includes a transmission method. In the transmission method, the terminal receives the first control information sent by the base station through the first control channel, and when the second control information is not obtained from the base station, according to the first control information. The information and the preset control information determine the transmission configuration parameters of the data channel, and perform data transmission with the base station through the transmission configuration parameters of the data channel; through this method, even if the terminal does not obtain the second control information from the base station side, the terminal can still use the The preset control information replaces the second control information, and is combined with the control information to determine a data channel, so that data transmission continues, data transmission efficiency is improved, and user experience on the terminal side is guaranteed.

Description

technical field [0001] The present invention relates to the field of communication, and in particular, to a communication method, device, terminal, base station and storage medium. Background technique [0002] On the one hand, in the prior art, two-level control channels are often used to transmit control information: the transmitting end uses the first control channel L1 to carry the first control information, and the first transmission configures the first control channel L1; at the same time, the transmitting end uses the second control channel L2 carries the second control information, and uses the second transmission to configure the second control channel L2. The first control information transmitted on the first control channel L1 and the second control information transmitted on the second control channel L2 are used to indicate the transmission configuration of the data channel. However, the second control channel L2 is generally not as robust as the first control...

AI Technical Summary

Problems solved by technology

[0004] With regard to the first aspect, the embodiments of the present invention provide a method and device for transmission and uplink reception, a terminal, a base station, and a storage medium, so as to solve the problem of communication between two ends of the communication when there are two levels of control information and one of the control information cannot be received correctly. The data transmission cannot be performed normally, which affects the data transmission efficiency; for the second aspect, the embodiment of the present invention provides a feedback policy determination method and device, a terminal and a storage medium to solve the problem that the sending end sends a first control information, two When receiving the second control information, it is impossible to understand the receiving end’s reception of the control information and data.
