Problems solved by technology

In the design of the above-mentioned two-layer control message, the terminal needs to demodulate the fast control information through blind detection in each sTTI. If the number of blind detections required to demodulate the fast control information is not reduced, the control information will be affected. The demodulation speed, for which there is no effective solution

Abstract

The present invention provides a method for managing downlink control information, a management device, a base station, and a terminal, wherein the method for managing downlink control information is used for a base station, and includes: configuring the first dedicated downlink control information corresponding to the terminal scheduled by the target TTI and The second dedicated downlink control information, wherein the second dedicated downlink control information is carried in the frequency domain range of the resource module group corresponding to the terminal, and the first dedicated downlink control information includes the resource module corresponding to the terminal Group identification information, the duration of the target TTI is less than 1 ms; sending the first dedicated downlink control information and the second dedicated downlink control information to the terminal. Through the technical solution of the present invention, the number of attempts of the terminal to blindly detect the second dedicated downlink control information can be effectively reduced, and the efficiency of demodulating the downlink control information can be improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a method for managing downlink control information, a device for managing downlink control information, a base station and a terminal. Background technique [0002] In the current LTE (Long Term Evolution) system, the downlink data sent by the base station to the terminal is carried in the PDSCH (Physical Downlink Shared Channel), and the downlink data corresponds to the downlink data. The PDSCH transmits DCI (Downlink Control Information, downlink control information) on PDCCH (Physical Downlink Control Channel, physical layer downlink control channel) transmitted in the same TTI (Transmission Time Interval). The DCI is used to indicate various information required by the terminal to demodulate the corresponding downlink data, such as the RB (Resource Block, resource module) where the downlink data is located, the modulation and coding format used, and the redundan...
