Method for using unlicensed spectrum and apparatus

A method comprising:

• receiving, from a terminal device, a first measurement result of each to-be-measured unlicensed frequency band in one or more to-be-measured unlicensed frequency bands, wherein the first measurement result comprises information about a to-be-measured unlicensed frequency band that meets at least one of first conditions in the one or more to-be-measured unlicensed frequency bands, wherein the information about the to-be-measured unlicensed frequency band comprises at least one of:
• reference signal received power (RSRP), reference signal received quality (RSRQ), or a signal to interference plus noise ratio (SINR), wherein the information is obtained based on the first measurement result and one or more second measurement results received from one or more other terminal devices, and wherein the information, and wherein the target unlicensed frequency band meets the at least one of first conditions comprising:
• the RSRP of the target unlicensed frequency band is less than or equal to a first threshold, the RSRQ of the target unlicensed frequency band is less than or equal to a second threshold, or the SINR of the target unlicensed frequency band is less than or equal to a third threshold;
• and
• determining, based on the first measurement result, position information of the terminal device.

A communication apparatus, comprising:

• a transceiver;
• at least one processor;
• and
• at least one memory coupled to the at least one processor and storing programming instructions for execution by the at least one processor to cause the communication apparatus to perform operations comprising:
• receiving, from at least two terminal devices, at least two measurement reports, wherein each of the at least two measurement reports comprises a measurement result of each to-be-measured unlicensed frequency band in one or more to-be-measured unlicensed frequency bands;
• obtaining, based on measurement results comprised in the at least two measurement reports, information about a target unlicensed frequency band that meets at least one of first conditions in the one or more to-be-measured unlicensed frequency bands, wherein the information about the target unlicensed frequency band comprises at least one of reference signal received power (RSRP) of the target unlicensed frequency band, reference signal received quality (RSRQ) of the target unlicensed frequency band, or a signal to interference plus noise ratio (SINR) of the target unlicensed frequency band;
• and
• transmitting, based on the information about the target unlicensed frequency band, a signal on a supplementary uplink (SUL), wherein a spectrum of the SUL comprises the target unlicensed frequency band.
