Claim of US Patent No. 11,071,090


1. A method for transmitting a synchronization signal, comprising:determining, by a transmitting end, the synchronization signal;
transmitting, by the transmitting end, the synchronization signal determined to a receiving end, and
notifying, by the transmitting end, the receiving end of configuration information related to the synchronization signal determined;
wherein the determining, by a transmitting end, the synchronization signal comprises: determining, by the transmitting end, X synchronization signal groups, wherein each of the X synchronization signal groups comprises a respective one of N1, N2, . . . Nx types of downlink synchronization signals corresponding to transmission configuration, X is an integer greater than or equal to 1, N1, N2, . . . Nx are all integers greater than or equal to 1 and a sum Ntot of a total number of classifications of the downlink synchronization signals included in the X synchronization signal groups equals to N1+N2+ . . . +Nx;
the notifying, by the transmitting end, the receiving end of configuration information related to the synchronization signal determined comprises: determining, by the transmitting end, M physical broadcast channels; notifying, by the transmitting end, the receiving end of the configuration information related to the synchronization signal determined through the M physical broadcast channels; wherein each of the M physical broadcast channels is bound to a respective one of Ntot types of the downlink synchronization signals, M is a positive integer less than or equal to Ntot; or the M physical broadcast channels are bound to part or all of the synchronization signals among the Ntot types of the downlink synchronization signals;
in the case that the configuration information related to the synchronization signal determined is notified to the receiving end by the transmitting end in the manner of being indicated by the sequence group to which the sequence of the synchronization signal belongs, at least one of the followings is met:it is promised by the transmitting end and the receiving end that available sequences of the synchronization signals are divided into Y sequence groups, wherein Y is a natural number greater than 1, wherein an index of each of the Y sequence groups is used for indicating at least one of the followings: the resource allocation information about a synchronization signal classification and/or a synchronization signal group to which the synchronization signal belongs; the resource configuration information about the X synchronization signal groups; and at least one parameter of a group consisting of: Ntot, N1, N2, . . . Nx and X;
it is promised by the transmitting end and the receiving end that the number of repetitions of the sequence of the synchronization signals is adopted for indicating at least one the followings: the resource allocation information about the synchronization signal classification and/or synchronization signal group to which the synchronization signal belongs; the resource allocation information about the X synchronization signal groups; and at least one parameter of a group consisting of: Ntot, N1, N2, . . . Nx and X;

in the case that the configuration information related to the synchronization signal determined is notified to the receiving end by the transmitting end in the manner of being indicated by the frequency domain mapping of the synchronization signal, features about the number of sub-carriers in the frequency domain mapping and/or positions of the sub-carriers are adopted for indicating at least one of the followings:the resource allocation information about the synchronization signal group corresponding to the synchronization signal; the resource allocation information about the X synchronization signal groups; and at least one parameter of a group consisting of: Ntot, N1, N2, . . . Nx and X; and

in the case that the configuration information related to the synchronization signal determined is notified to the receiving end by the transmitting end in the manner of being indicated by the time domain mapping of the synchronization signal, a parameter about a transmitting time interval of the same type of synchronization signal in the time domain is adopt for indicating at least one of the followings:
the resource allocation information about the synchronization signal group corresponding to the synchronization signal; the resource allocation information about the X synchronization signal groups; and at least one parameter of a group consisting of: Ntot, N1, N2, . . . Nx and X.
