Abstract: An information indicating method, an information determining method, a terminal and a base station are provided. The information indicating method includes: indicating, by using a predetermined parameter of a physical broadcast channel (PBCH) in a first system synchronization block (SSB), whether the first SSB includes associated remaining minimum system information (RMSI); or indicating, by using a predetermined parameter of a PBCH in a first SSB, that the first SSB does not include associated RMSI, and indicating frequency offset information of a synchronization raster where a second SSB is located, where the second SSB is an SSB with the associated RMSI.

Abstract: The embodiments of the present application relate to the technical field of wireless communications, and in particular to a method and device for detecting data transmission and received signals, which are used for solving the problem in the prior art that it is disadvantageous for signal detection due to the fact that when a receiving end is detected in the scenario that each column of an encoding matrix of PDMA corresponds to one layer of data stream, multiple layers of data modulation symbols are superposed. The embodiments of the present application adjust various layers of data modulation symbols modulated by an initial modulation constellation diagram according to a modulation constellation rotating factor corresponding to various layers of data modulation symbols, so that the modulation constellation diagrams corresponding to various layers of data modulation symbols are not superposed, thereby preventing the problem of being disadvantageous for signal detection of a receiving end due to the fact that multiple layers of data modulation symbols are superposed in the scenario that each column of the encoding matrix of PDMA corresponds to one layer of data stream; and further improving the system performance.

Abstract: The present application relates to the field of wireless communications, and in particular, to a method and device for random access, for use in resolving the problem in the prior art of conflict between a time domain resource used by a terminal for random access and a time domain resource occupied for transmission of a SS Block and/or RMSI. In embodiments of the present application, a terminal determines a PRACH time domain resource configured by a base station for the terminal; when determining that at least one time slot comprises a first type of OFDM symbols used for transmission of a SS Block and/or RMSI, the terminal performs random access by means of OFDM symbols different from the first type of OFDM symbols in the at least one time slot. In the embodiments of the present application, the terminal performs random access by means of OFDM symbols different from the first type of OFDM symbols in the time slot, so that conflict between the time domain resource used for random access and the time domain resource occupied for transmission of the SS Block and/or RMSI is avoided, and the system performance is further improved.
