    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: The application pertains to determining a rank of channel loss extent. A base station sends to a terminal a signaling indicating that there are N ranks of channel loss extent. Each rank has a corresponding number of random access preamble repetitions. The base station receives from the terminal device one or more transmissions of a random access preamble in a first number of repetitions of the random access preamble. The base station determines the rank of channel loss extent according to a random access preamble group in which the received random access preamble is located, or the first number of repetitions of the received random access preamble. A channel loss is a reference signal received power (RSRP). After determining the rank of channel loss extent, the base station determines a second number of repetitions corresponding to the determined rank of channel loss extent, for sending or receiving uplink/downlink information.

    Abstract: The present disclosure provides a transmission method for a common message and a device, which relates to a field of communication technologies and is invented for effectively ensuring that both a low cost MTC terminal and a normal LTE terminal may reliably receive the common message. The transmission method for the common message includes: determining common message transmission time instances corresponding to a first terminal, wherein the common message transmission time instances corresponding to the first terminal are a part of time instances of cell common message transmission time instances; sending a common message at the determined common message transmission time instances corresponding to the first terminal, a bandwidth of frequency resources used for sending the common message being no larger than a data processing bandwidth that the first terminal is capable of supporting. The present disclosure may be used in an M2M application based on an LTE network.
