    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.

    Abstract: An information transmission method and an information transmission device are provided, so as to determine redundancy versions corresponding to a plurality of consecutive subframes as an identical redundancy version, thereby to enable identical information to be transmitted within the plurality of consecutive subframes after a rate matching and enable an opposite end to perform coherent combination on the information transmitted within the plurality of consecutive subframes. The information transmission method includes steps of: determining, by a local end serving as a transmitting end, information to be repeatedly transmitted within a repetition time period containing a plurality of subframes; and determining, by the local end, a redundancy version corresponding to each subframe in the repetition time period, performing a rate matching on a bit stream acquired by encoding the information based on the redundancy version corresponding to the subframe, and transmitting the bit stream processed through the rate matching to an opposite end, where a plurality of consecutive subframes among the subframes in the repetition time period corresponds to an identical redundancy version.

    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.
