Abstract

The invention provides a data analysis method and device. The method comprises the following steps: enabling a base station to configure downlink data in downlink control information of a physical downlink control channel; and sending the configured physical downlink control channel to a terminal, so that the terminal analyzes the configured downlink control information from the configured physical downlink control channel, and according to the frequency domain resource indication value in the configured downlink control information, analyzes the downlink data from the configured downlink control information. According to the invention, the downlink data is directly configured in the downlink control information of the physical downlink control channel, and the configured physical downlink control channel is sent to the terminal, so that the terminal can acquire the downlink data only by analyzing the downlink control information of the physical downlink control channel, the time delay caused by PDSCH analysis can be reduced, and physical resources occupied by PDSCH issuing can be reduced.

Description

technical field [0001] The present invention relates to the field of communication technologies, in particular to a data analysis method and device. Background technique [0002] In the NR (New Radio, new air interface) system, the downlink usually needs to solve the PDCCH (Physical Downlink Control Channel, Physical Downlink Control Channel) and PDSCH (Physical Downlink Shared Channel, Physical Downlink Shared Channel) at the same time to obtain downlink data. Such as figure 1 Shown is the existing data parsing process, which specifically includes: the terminal completes downlink synchronization with the base station through SSB (Synchronization Signal Block, synchronization signal block), and completes uplink synchronization with the base station through access. Then, the terminal monitors the PDCCH. After monitoring that the PDCCH blind detection is successful, the terminal needs to indicate the frequency domain resource assignment (Frequency domain resource assignment) ...
