Provided are a method, apparatus and system for transmitting and receiving control information. The method for transmitting control information includes that: a base station determines, according to predefined information, resources used for repeatedly sending control information, wherein the predefined information at least includes one of: a start sub-frame k0, a System Frame Number (SFN), a repetition number or a repetition level N and a User Equipment (UE) Identity (ID); and the base station repeatedly sends the control information on the resources.
Abstract:
Disclosed is a system information transmitting method, including: in one modification period, determining a frequency domain location for transmitting a coverage enhancement system message and time domain locations for periodically transmitting a coverage enhancement system message; a base station periodically transmitting the coverage enhancement system message; and the determined frequency domain location and the time domain locations for periodically transmitting are different from the re-transmission locations of main information block (MIB) information. Also disclosed are a receiving method corresponding to the transmitting method, as well as devices corresponding to the transmitting and receiving methods. The method and device of the embodiment of the present document is used to determine the time domain and frequency domain locations of the system message, thus avoiding the problem that an LTE network can't be accessed due to an address conflict caused by periodically transmitting system information for a plurality of times
