    Abstract: This application relates to the mobile communications field, and in particular, to a random access technology in a wireless communications system. This application provides a method for sending a random access preamble sequence, an apparatus, and a system. In this solution, a terminal device obtains a cyclic shift value that satisfies a high-speed movement scenario and sends a random access preamble sequence corresponding to the cyclic shift value. Impact brought by the high-speed movement scenario is considered when the random access preamble sequence is determined, thereby avoiding interference between terminal devices in the high-speed scenario.

    Abstract: A channel estimation method, a base station, user equipment (UE), and a system are provided. The method includes: setting up, by a base station, a connection to user equipment UE; and sending, to the UE, notification information indicating that the UE is in a radio remote scenario, where the notification information is used to instruct the UE to perform channel estimation by using a channel estimation algorithm applicable to the radio remote scenario, and the channel estimation algorithm is used to perform channel estimation on a signal that is obtained after downlink signals from multiple radio remote units RRUs are superposed. The UE can perform channel estimation by using the appropriate channel estimation algorithm, to effectively improve accuracy of the channel estimation, thereby effectively improving a downlink data throughput of the UE.

    Abstract: A channel transmission method, a base station, and a terminal device are provided. In one example method, a base station determines a communication mode to be used between the base station and a terminal device. The base station determines a transmission parameter set of a first channel according to the determined communication mode. The communication mode corresponds to the transmission parameter set of the first channel. The base station transmits information associated with the first channel to the terminal device.

    Abstract: The present disclosure provides an enhanced physical channel transmission method. The method includes: determining first information corresponding to each of one or more enhanced physical channel transmission levels, where the first information includes repetition configuration information and enhanced transmission configuration information that are of enhanced transmission of a physical channel; determining, according to the first information, a start radio frame of an enhanced physical channel transmission opportunity corresponding to each enhanced physical channel transmission level and a start position, in the start radio frame, of the enhanced physical channel transmission opportunity, where the start position is a start subframe, or the start position is a start physical channel transmission opportunity; and performing the enhanced transmission of the physical channel by using the start position in the start radio frame as a start point. Therefore, enhanced transmission of a physical channel for terminals of different levels is implemented.
