Time period configuration method and apparatus, communication device,and storage medium

A method for configuring a period for synchronous signal block (SSB) measurement, performed by a serving cell, comprising:

• sending ephemeris information, wherein the ephemeris information comprises at least one of:
• ephemeris information of a serving cell satellite of the serving cell, or ephemeris information of a neighboring cell satellite of a neighboring cell, wherein the ephemeris information of the serving cell is configured to determine a position of the serving cell satellite of the serving cell, and the ephemeris information of the neighboring cell is configured to determine a position of a neighboring cell satellite of the neighboring cell,
• receiving update indication information reported by a terminal;
• and
• updating a period configuration of the period for SSB measurement based on the update indication information, wherein the period configuration comprises indication information for determining the period for SSB measurement;
• wherein updating the period configuration of the period for SSB measurement based on the update indication information comprises:
• updating the period configuration of the period for SSB measurement based on a transmission delay difference carried by the update indication information, wherein the transmission delay difference comprises one of:
• a difference obtained by subtracting the transmission delay between the terminal and the serving cell from the transmission delay between the terminal and the neighboring cell, or a difference obtained by subtracting the transmission delay between the terminal and the neighboring cell from the transmission delay between the terminal and the serving cell.

A communication device, comprising:

• a processor, a transceiver, a memory, an executable program stored on the memory and executed by the processor,
• wherein the processor is configured to execute the executable program to:
• receive ephemeris information of a serving cell satellite of a serving cell and ephemeris information of a neighboring cell satellite of a neighboring cell sent by the serving cell, wherein the ephemeris information of the serving cell is configured to determine a position of the serving cell satellite of the serving cell, and the ephemeris information of the neighboring cell is configured to determine a position of a neighboring cell satellite of the neighboring cell,
• detect a synchronous signal block (SSB) of a neighboring cell within a period for SSB measurement, wherein the period for SSB measurement comprises at least one of:
• an SSB measurement timing configuration (SMTC) window or a measurement gap;
• and
• report update indication information based on a detection result of the SSB, wherein the update indication information is configured to update a period configuration at a network side, and the period configuration comprises indication information for determining the period for SSB measurement,
• wherein reporting the update indication information based on the detection result of the SSB comprises:
• determining a transmission delay difference, wherein the transmission delay difference comprises one of:
• a difference obtained by subtracting a transmission delay between the terminal and the serving cell from the transmission delay between the terminal and the neighboring cell, or a difference obtained by subtracting the transmission delay between the terminal and the neighboring cell from the transmission delay between the terminal and the serving cell;
• and
• reporting the update indication information based on the transmission delay difference.
