Abstract: The present disclosure relates to subframe configuration indication methods and apparatus. One example method includes determining, by a network device, a quantity of downlink symbols included in an (n+N)th subframe, where N is an integer greater than or equal to 2, and n is an integer greater than or equal to 0, and sending, by the network device and in both a control region and a data region of an nth subframe, downlink control information (DCI) through downlink control channels, where the DCI is used to indicate the quantity of downlink symbols included in the (n+N)th subframe.

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: Embodiments of this application provide methods for detecting or sending a discovery signal, associated base station, and associated user equipment. A method includes: performing, by a base station, first carrier sense on first R subframes of one radio frame in a time sequence in a first discovery signal measurement timing (DMTC) window; and if the first carrier sense succeeds, sending, by the base station, a discovery signal in M consecutive subframes, where M is greater than or equal to 2, and the first subframe of the M consecutive subframes is located in the radio frame in the first DMTC window. The embodiments of this application are used to support enhanced discovery signal transmission by using a new DMTC, so that to implement accessing UE in a weak coverage scenario, thereby ensuring cell coverage performance.

Abstract: Embodiments of this application provide a communication method and a communications apparatus. An example method includes: sending an ePDCCH to a terminal, where the ePDCCH carries scheduling information of a SIB; and sending a PDSCH to the terminal based on the scheduling information of the SIB, where the PDSCH carries the SIB.

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.
