Abstract: A communication method and an apparatus are provided, where the method includes: determining, by a base station, a pre-configured value; and sending, by the base station, a downlink subframe in a first subframe, where the downlink subframe carries a control format indicator and a physical downlink control channel, the control format indicator is used to indicate a quantity of symbols occupied by the physical downlink control channel, and the base station determines a value of the control format indicator based on the pre-configured value or the quantity of symbols occupied by the physical downlink control channel that needs to be sent in the downlink subframe. In this case, in a WCE scenario, PCFICH coverage enhancement may not be performed any longer, and therefore resource consumption is reduced and impact on PDCCH performance is avoided.

Abstract: Example coverage mode identification methods and apparatus are described. One example method includes determining a first coverage mode by a terminal. The terminal determines a preamble sequence based on the first coverage mode, and sends the preamble sequence to a base station, where the preamble sequence is used to determine the first coverage mode. Because the base station can determine the coverage mode of the terminal by using only the preamble sequence sent by the terminal, without using a channel used to receive a signal of the terminal, resources do not need to be grouped or planned, and there is no need to strictly distinguish between different coverage mode sets or groups.
