SSB measurement method and apparatus

A terminal device, comprising at least one processor;

• and one or more memories coupled to the at least one processor and storing programming instructions for execution by the at least on processor to cause the terminal device to:
• receive first information, wherein the first information indicates a time domain position of a synchronization signal/physical broadcast channel block (SSB) sent by a serving cell;
• receive second information, wherein the second information indicates a set of SSBs that the terminal device needs to measure and that are sent by a neighboring cell;
• measure, in a first measurement window based on the first information, the SSB sent by the serving cell, wherein a first SS/PBCH block measurement timing configuration (SMTC) window and a second SMTC window are configured for one frequency, the first SMTC window has same offset and same length as the second SMTC window, the first SMTC window has a longer periodicity than the second SMTC window, and the terminal device selects the first SMTC window for measurement of a cell on the one frequency in response to determining that configuration information does not explicitly indicate an SMTC window applicable to the cell;
• and
• measure, in a second measurement window based on the second information, the SSB sent by the neighboring cell.

• receive second information, wherein the second information indicates a set of SSBs that the terminal device needs to measure;
• measure, in a first measurement window based on the first information and the second information, the SSB sent by the serving cell, wherein the first information comprises a first bitmap, the second information comprises a second bitmap, and wherein the programming instructions, when executed by the at least one processor, cause the terminal device to:
• when a value of an Nth bit in the first bitmap is 1 and a value of an Nth bit in the second bitmap is 0, refrain from measuring an SSB indicated by an SSB index corresponding to the Nth bits, wherein N is an integer greater than or equal to 0;
• and
• when a value of an Mth bit in the first bitmap and a value of an Mth bit in the second bitmap both are 1, measure an SSB indicated by an SSB index corresponding to the Mth bits, wherein M is an integer greater than or equal to 0, and M is different from N;
• and
• measure, in a second measurement window based on the second information, an SSB sent by a neighboring cell.
