Abstract: A backscatter communication method and apparatus provides operation including: receiving a first excitation signal from a first device; determining a first resource based on a candidate resource; and sending a backscattered signal of the first excitation signal to a second device based on the first resource. This can reduce a probability of selecting a same resource as another device to some extent, so that a conflict is reduced, and an access success rate of a backscatter device can be improved.

Abstract: A random access method includes determining, by a network device, configuration information and sending the configuration information to a terminal. The configuration information indicates at least a quantity of random access preambles transmitted on one random access resource, a quantity of contention-based random access preambles transmitted on the one random access resource, a quantity of contention-free random access preambles transmitted on the one random access resource, the quantity of random access preambles associated with one downlink signal, the quantity of contention-free random access preambles associated with the one downlink signal, the quantity of contention-based random access preambles associated with the one downlink signal, or a quantity of transmitted downlink signals associated with the one random access resource.

Abstract: A random access method and apparatus are provided. In the method, a configuration information element indicating a quantity of downlink signals per random access occasion and a first indication indicating a first downlink signal are sent by a network device to a terminal, and the terminal determines a correspondence between the first downlink signal and a random access occasion is determined based on the configuration information element, and sends a random access preamble via a random access occasion corresponding to the first downlink signal . In this way, the first random access occasion can be relatively accurately determined, and then a random access resource used for random access can be relatively precisely determined.

Abstract: This application provides a random access method and apparatus. In the method, a terminal device may determine a first random access resource for sending a random access preamble by using reference signal grouping information. This helps the terminal device send the random access preamble to a network device on the first random access resource, thereby improving a random access success rate.

Abstract: This application provides a signal transmission method and apparatus, a reflector, and a receiver. In one example method, a reflector receives W excitation signals, where W exciters may be configured to carry data and a reference signal that are reflected by the reflector; and the reflector reflects data and L reference signals to a receiver, where the L reference signals are respectively carried in L excitation signals in the W excitation signals, where W and L are both integers greater than or equal to 1, and L is less than or equal to W.

Abstract: Embodiments of this application provide a synchronization signal transmission method, a network device, and a terminal device. The method includes: determining, by a network device, time domain positions for sending m synchronization signal blocks, where the time domain positions are {s1, s2, . . . , sm}+n×T, s1 represents a start symbol index of the first synchronization signal block in a time unit, s2 represents a start symbol index of the second synchronization signal block in the time unit, sm represents a start symbol index of an mth synchronization signal block in the time unit, the time unit includes T symbols; and sending, by the network device, the synchronization signal blocks to a terminal device in the time domain positions of the synchronization signal blocks. The technical solutions provided in this application have relatively high flexibility, and can meet, to some extent, a synchronization signal block sending requirement for a high-frequency technology.
