Abstract: The present application relates to the technical field of wireless communications, and in particular, to a PBCH transmission method, system, and device, which are used to transmit an enhanced PBCH. The method of the present application comprises: a network side device determining a resource of a coverage-enhanced PBCH mapped in at least one radio frame; and the network side device transmitting the coverage-enhanced PBCH on the determined resource. In the present application, a network side device determines a resource of a coverage-enhanced PBCH mapped in at least one radio frame, and transmits the coverage-enhanced PBCH on the determined resource. Because a resource that bears a coverage-enhanced PBCH can be determined, thereby implementing transmission of the coverage-enhanced PBCH and improving system performance.

Abstract: Disclosed is a random access channel transmission method that is applicable at a terminal side. The method comprises: a terminal acquires a channel quality; the terminal determines, on the basis of a mapping relation between channel qualities and PRACH resources, a PRACH resource corresponding to the channel quality acquired; and, the terminal performs a PRACH transmission on the PRACH resource determined. Also disclosed are a random access channel transmission method that is applicable at a network side, a corresponding terminal device, and a corresponding base station. Employment of the present invention allows the terminal to select, on the basis of the channel quality of self, the corresponding random access channel resource for random access channel transmission.

Abstract: Disclosed are a signal processing method, a base station, a terminal, and a system. A base station side method comprises: sending a synchronization signal to a terminal through a predetermined first time-frequency resource; sending a supplemental synchronization signal different from the synchronization signal to the terminal through a predetermined second time-frequency resource, the synchronization signal and the supplemental synchronization signal being corresponding to a same physical layer cell identifier. In the technical solution provided by the embodiments of the present invention, in addition to that the synchronization signal is sent, the supplemental synchronization signal is also sent, and it is equivalent to increase of the transmission frequency of the synchronization signal. In a case where the network coverage is poor, the increase of the transmission frequency of the synchronization signal can increase the probability that the terminal completes cell searching by performing relevant detection on the same number of signals, so as to not only shorten the time required by the terminal to perform cell searching, but also decrease the amount of data buffered by the terminal, thereby decreasing the requirements on the buffer of the terminal.
