Signal strength measurement method, and related apparatus and system

A terminal device, comprising:

• a receiver, configured to receive first indication information from a network device, wherein the first indication information comprises first sub-information, second sub-information, and third sub-information, the first sub-information is used to indicate a measurement period for measurement, the measurement period comprises at least one second time unit, the second time unit comprises at least two first time units, the third sub-information is used to indicate an offset of a start position of a second time unit for measurement relative to a start position of the measurement period, and the second sub-information is used to indicate an offset of a start position of a first time unit for measurement in the measurement period relative to the start position of the second time unit for measurement;
• a processor, configured to determine a measurement resource based on the first indication information received by the receiver, wherein the measurement resource is determined in the measurement period based on the start position of the first time unit and the start position of the second time unit;
• perform signal strength measurement on a signal on the measurement resource determined by the processor, to obtain a measurement result;
• and
• a transmitter, configured to send the measurement result obtained by the processor to the network device.

An information transmission device, comprising:

• a computer-readable storage medium storing program code;
• and
• computer hardware coupled to the computer-readable storage medium and configured to execute the program code to cause the information transmission device to:
• receiving first indication information from a network device, wherein the first indication information comprises first sub-information, second sub-information, and third sub-information, the first sub-information is used to indicate a measurement period for measurement, the measurement period comprises at least one second time unit, the second time unit comprises at least two first time units, the third sub-information is used to indicate an offset of a start position of a second time unit for measurement relative to a start position of the measurement period, and the second sub-information is used to indicate an offset of a start position of a first time unit for measurement in the measurement period relative to the start position of the second time unit for measurement;
• determining a measurement resource based on the first indication information, wherein the measurement resource is determined in the measurement period based on the start position of the first time unit and the start position of the second time unit;
• performing signal strength measurement on a signal on the measurement resource, to obtain a measurement result;
• and
• sending the measurement result to the network device.
