A method for measuring a synchronization signal, comprising: receiving, by a user equipment, configuration information sent by a network device, wherein the configuration information is used to instruct the user equipment to use a measurement set to measure a synchronization signal, wherein the measurement set is used by the user equipment in a connected state to measure a synchronization signal, the measurement set is a first synchronization signal block, SS block, set and the number of SS blocks included in the first SS block set is smaller than the number of SS blocks included in a second SS block set which comprises an SS block used by the user equipment in an idle state to measure a synchronization signal; adopting, by the user equipment, the measurement set to measure a synchronization signal when the user equipment is in a connected state, characterized in that the configuration information comprises: a measurement period of a signal in the SS block; a time offset of measurement signals in two adjacent SS block periods; and second indication information which is used to instruct the user equipment to adopt K designated signals in M designated SS blocks of the second SS block set in each SS block period to measure a synchronization signal, and wherein M and K are positive integers; and the configuration information further comprises third indication information which is used to instruct the user equipment to measure a synchronization signal for W designated cells including a first cell and a second cell, wherein the first cell is a cell in which the user equipment is located, the second cell is a cell in which the user equipment is not located, and W is a positive integer. receiving, by a user equipment, configuration information sent by a network device, wherein the configuration information is used to instruct the user equipment to use a measurement set to measure a synchronization signal, wherein the measurement set is used by the user equipment in a connected state to measure a synchronization signal, the measurement set is a first synchronization signal block, SS block, set and the number of SS blocks included in the first SS block set is smaller than the number of SS blocks included in a second SS block set which comprises an SS block used by the user equipment in an idle state to measure a synchronization signal; adopting, by the user equipment, the measurement set to measure a synchronization signal when the user equipment is in a connected state, characterized in that the configuration information comprises: a measurement period of a signal in the SS block; a time offset of measurement signals in two adjacent SS block periods; and second indication information which is used to instruct the user equipment to adopt K designated signals in M designated SS blocks of the second SS block set in each SS block period to measure a synchronization signal, and wherein M and K are positive integers; and the configuration information further comprises third indication information which is used to instruct the user equipment to measure a synchronization signal for W designated cells including a first cell and a second cell, wherein the first cell is a cell in which the user equipment is located, the second cell is a cell in which the user equipment is not located, and W is a positive integer.
