Abstract: In a random access method, random access preambles are grouped, and an electronic device selects a random access preamble from the grouped random access preambles, and receives an indication of a base station for the electronic device to send a message 3 repeatedly or in a diversity mode, so that the electronic device sends the message 3 repeatedly or in a diversity mode in a random access process. Accordingly, a probability of detecting the message 3 by the base station can be effectively improved, coverage performance of an uplink signal is improved, and/or resources of the base station are less wasted.

Abstract: Methods, apparatuses, and storage media for transmitting a system information block are described. In an example implementation, a network device sends indication information to a terminal device. The terminal device determines a period of periodic transmission of a system information block (SIB) based on the received indication information, and receives, based on the period, a SIB1 sent by the network device. Alternatively, the terminal device determines a transmission location of aperiodic transmission of a system transport block based on the indication information, and receives, at the indicated transmission location, a SIB1 sent by the network device.

Abstract: A random access/responding method and device are provided. In some embodiments, at least two random access preambles can be received before responding to random access of a terminal device, where each of the at least two random access preambles includes at least one sequence. In some embodiments, one random access preamble can be received before responding to random access of a terminal device, where the one random access preamble includes at least two sequences. The sequences in the received random access preambles can be checked. A successfully detected sequence or a random access preamble with the successfully detected sequence can then be responded to. In this way, responding to a plurality of successfully detected random access preambles or a plurality of successfully detected sequences included in one random access preamble is implemented.

Abstract: This application provides a random access preamble transmission method and an apparatus. In one example method, a terminal receives indication information, and may indicate, with reference to the indication information, whether a first path loss is the same as a second path loss, and determine the first path loss based on the second path loss. Then, the terminal may set, based on a path loss for transmitting a random access preamble between the terminal and a network device, a transmit power for sending the random access preamble.
