Abstract: To facilitate sending a reference signal in a wireless communication environment, a transmitter sends a reference signal in a first time-frequency resource to a user equipment (UE); the transmitter sends data information in a first portion of a second time-frequency resource different from the first time-frequency resource to the UE; and the transmitter excludes data information from being sent in a second portion of the second time-frequency resource. The second portion of the second time-frequency resource is designated for use by another transmitter for sending another reference signal to the UE.

Abstract: Example control information format processing methods, base stations, and apparatuses are described herein. One example method includes determining a control information format of downlink control information. When the control information format of the downlink control information is a first control information format, a first field included in the downlink control information corresponding to the first control information format indicates a valid setting. When the control information format of the downlink control information is a second control information format, a second field included in the downlink control information corresponding to the second control information format indicates an invalid setting. The downlink control information is then sent to user equipment (UE).

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.
