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: Methods, apparatus, and systems for data or information transmission are provided. In one aspect, a data sending method by a terminal device includes: determining indication information, determining, based on the indication information, a transport block size (TBS) used to send data, and sending the data based on the determined TBS. The terminal device can determine at least two of first information indicating that the TBS is a first TBS, second information indicating that the TBS is a second TBS, or third information indicating the terminal device to select a TBS from a TBS set as a third TBS used by the terminal device to send data. The TBS set is determined based on the first TBS, and can include at least one of the second TBS or the third TBS. The indication information includes one of the at least two of the first, second, or third information.

Abstract: A terminal device receives downlink control information sent by a network device. The downlink control information includes a resource allocation field. The resource allocation field includes ⌈ log 2 ⌊ N RB UL 6 ⌋ ⌉ high-order bits and M low-order bits. When the resource allocation field is used to indicate an allocated subcarrier resource, K bit states in bit states of the M bits are used to indicate allocation of subcarrier resources, and a quantity of subcarriers indicated by each of the K bit states is less than 12. The terminal device determines, based on the resource allocation field, whether the resource block or the subcarrier resource is allocated. The terminal device sends information on the allocated resource block or the subcarrier resource. The method and the device provided in embodiments of the application can be applied to a communications system.

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.
