Description
Technical field
The present invention relates to the communications field, in particular to a kind of transmission of Downlink Control Information, the detection method and the device of down control channel.
Background technology
MTC user terminal (MTC User Equipment abbreviates MTC UE as) claims the M2M user communication device again, is the main application form of present stage Internet of Things.But low power consumption and low cost is the important leverage of its large-scale application.At present, the M2M technology has obtained the support of international well-known manufacturers such as NEC, HP, CA, Intel, IBM, AT﹠T and the approval of various countries mobile operator.The M2M equipment of existing market deploy is mainly based on global mobile communication (Global System of Mobile communication abbreviates GSM as) system.In recent years, because the spectrum efficiency height of Long Term Evolution (Long Term Evolution abbreviates LTE as), increasing mobile operator selects the evolution direction of LTE as the future wireless system.Many kinds of class data services of M2M based on LTE will be more attractive also.It is lower than the MTC terminal of gsm system to have only the one-tenth instinct of LTE-M2M equipment to accomplish, the M2M business could really forward in the LTE system from GSM.
The cost that influences MTC UE mainly is Base-Band Processing and radio frequency.And reduce to send and receive bandwidth is to reduce a kind of very effective mode of MTC UE cost.The maximum support transmitting-receiving bandwidth that is MTC UE is less than the traditional LTE terminal of routine (Ordinary Legacy R8/9/10UE is called for short OL UE) desired maximum transmitting-receiving bandwidth 20MHz under single carrier wave.The reception of MTCUE and send bandwidth and can be set to the little bandwidth that 1.4MHz or LTE systems such as 3MHz or 5MHz are supported.
Radio frames in the LTE system (Radio Frame abbreviates RF as) comprises the frame structure of Frequency Division Duplexing (FDD) (Frequency Division Duplex abbreviates FDD as) pattern and time division duplex (Time Division Duplex abbreviates TDD as) pattern.
