Abstract

The invention provides a transmission, acquiring method and apparatus of public downlink control information. The method herein includes the following steps: performing grouping scrambling on public downlink control information through preset grouping scrambling information which corresponds to each terminal grouping in a one by one manner, obtaining grouping public downlink control information; transmitting a Physical Downlink Control Channel (PDCCH) which carries the object public downlink control information to a terminal, such that the terminal demodulates the PDCCH based on the preset grouping scrambling information, acquiring the object public downlink control information, wherein the object public downlink control information refers to public downlink control information which corresponds to the object terminal grouping belonged to the terminal in the grouping public downlink control information. According to the invention, the method realizes the purpose of transmitting and acquiring public downlink control information based on terminal grouping.

Description

technical field [0001] The present disclosure relates to the communication field, and in particular, to methods and devices for transmitting and acquiring public downlink control information. Background technique [0002] In related technologies, the transmission of the terminal is based on the scheduling of the base station. For downlink transmission, the terminal will receive PDCCH (Physical Downlink Control Channel, physical layer downlink control channel) to instruct the terminal to receive information such as time domain position, frequency domain position and transmission format of the data. The PDCCH can be divided into a common PDCCH and a terminal-specific PDCCH. The common PDCCH is used to carry common downlink control information (Downlink Control Information, downlink control information) for multiple terminals. The terminal obtains common downlink control information by demodulating the common PDCCH. [0003] 5G or NR (New Radio) system-related standardizatio...
