Abstract

The invention provides a processing method and a system for downlink control information (DCI), a base station and user equipment, wherein the method comprises the following steps: the base station confirms the position information of the downlink control information of the active user equipment in a downlink subframe; the base station takes along the downlink control information of the user equipment in the downlink subframe according to the position information of the downlink control information of the user equipment in the downlink subframe; the base station sends the downlink subframe to the user equipment so as to enable the user equipment to acquire the position information of the downlink control information of the user equipment in the downlink subframe, and the user equipment acquires the downlink control information of the user equipment from the downlink subframe according to the position information of the downlink control information of the user equipment in the downlink subframe. With the adoption of the technical proposal provided by the invention, probability of false detection does not exist, the implement is easy, and the DCI acquiring efficiency is improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to a processing method and system, base station and user equipment of Downlink Control Information (DCI). Background technique [0002] Orthogonal Frequency Division Multiplexing (OFDM) technology is the basis of the Home-Plug Power-line Alliance (HPA) industry specification. It uses a discontinuous multi-tone technology and will be called A large number of signals in different frequencies of the carrier are combined into a single signal to complete signal transmission. [0003] In the prior art, the more popular application of OFDM technology for commercial networking is in the Long Term Evolution (LTE) system. For example, in the LTE system, three downlink physical control channels are defined: Physical Control Format Indicator Channel (PCFICH), Physical Hybrid Automatic Repeat Request Indicator Channel (Physical HARQ Indicator Channel; PHICH) and Physical Downlink Co...
