The indication information is used for indicating a position relationship between the first terminal and the second terminal and/or a condition required to be met by the signal strength of the target signal. The target signal is a signal transmitted on a physical side link.
In one possible implementation, for example, as shown in fig. 2A, in a case where the first terminal has no network signal coverage, the second terminal serves as a relay terminal (relay UE), and the first terminal serves as a remote terminal (remote UE). The base station configures the indication information for the first terminal, the base station may send the indication information to the second terminal through a connection reconfiguration signaling, and the second terminal sends the indication information to the first terminal through a physical sidelink (sidelink).
In another possible implementation manner, for example as shown in fig. 2B, the indication information may be configured directly for the first terminal by the second terminal, and in a case that the first terminal has no network signal coverage, the second terminal sends the indication information to the first terminal through the physical sidelink.
In the above embodiment, the second terminal may send the indication information to the first terminal, so that the first terminal in the area without network coverage performs cell measurement when determining that the signal strength and/or the location relationship satisfy the condition. The purpose of saving the electric quantity of the first terminal is achieved.

in step 301, indication information transmitted by the second terminal is received.
In the embodiment of the present disclosure, the indication information is used to indicate a position relationship between the first terminal and the second terminal and/or a condition that needs to be satisfied by the signal strength of the target signal. Wherein the target signal is a signal transmitted on a physical side link. The target signal may be a discovery signal and/or a sidelink signal.
In step 302, it is determined that the signal strength and/or the positional relationship satisfy a condition.
In one possible implementation manner, the first terminal may determine that the signal strength and/or the position relationship satisfies a condition within a preset time period.
In step 303, cell measurements are performed.
In the above embodiment, the first terminal performs cell measurement when it is determined that the signal strength and/or the position relationship satisfy the condition. The method and the device can avoid continuous cell measurement when the first terminal is in an area without network coverage, and achieve the purpose of saving the electric quantity of the terminal.
In some optional embodiments, the indication information includes a correspondence between the condition and a measurement object, and the measurement object is an object to be measured by the cell measurement.

The signal strength of the target signal may be RSRP of the target signal. The target signal may be a discovery signal and/or a sidelink signal. The relationship between the signal strength of the target signal and the preset signal threshold may be that the signal strength is greater than the preset signal threshold, or the signal strength is less than the preset signal threshold.
In a possible implementation manner, the first relative relationship is that the signal strength is greater than a preset signal threshold, and when the target signal is the discovery signal, the first terminal performs cell measurement when the RSRP of the discovery signal is greater than the preset signal threshold.
In a possible implementation manner, the first relative relationship is that the signal strength is smaller than a preset signal threshold, and when the target signal is a sidelink signal, the first terminal performs cell measurement when RSRP of the sidelink signal is smaller than the preset signal threshold.
In a possible implementation manner, the first relative relationship is that the signal strength is smaller than a preset signal threshold, and when the target signal is the discovery signal and the sidelink signal, the first terminal may perform cell measurement when both the RSRP of the sidelink signal and the RSRP of the discovery signal are smaller than the preset signal threshold.

In one possible implementation manner, the first terminal may perform cell measurement when the distance value between the first terminal and the second terminal is smaller than the preset distance value.
In one possible implementation, the first terminal may perform cell measurements in the same area as the second terminal.
In another possible implementation, the first terminal may perform cell measurements in a different area from the second terminal.
In a possible implementation manner, the first terminal may determine the longitude and latitude of the first terminal, so as to determine the identifier of the area where the first terminal is located, and when the identifier of the area where the first terminal is located is consistent with the identifier of the designated area, the first terminal performs cell measurement.
In one possible implementation, the condition includes an identifier of the second terminal, the first terminal may detect multiple discovery signals from different terminals or may establish a physical sidelink with multiple terminals when the first terminal is in an area without network coverage, and the first terminal may determine the second terminal based on the identifier of the terminal indicated by the indication information.
I.e. the condition indicated by the indication information corresponds to the identity of the relay UE. The first terminal determines a second terminal as a relay UE based on the indication information, thereby determining whether the signal strength and/or the positional relationship satisfy the condition.
In one possible implementation, the first terminal may perform cell measurement if any one of the above conditions is met.
In one possible implementation, the first terminal may perform cell measurement when the two or more conditions are satisfied. For example, the first terminal may perform cell measurement when the signal strength of the target signal is greater than a preset signal threshold, and the first terminal and the second terminal are in the same area.
Optionally, the first terminal may also determine a correspondence between the condition and the measurement object based on agreement.
Optionally, the correspondence between the condition and the measurement object includes any one of: one condition corresponds to one measurement object; the plurality of conditions correspond to one measurement object; one condition corresponds to a plurality of measurement objects.
In a possible implementation manner, the corresponding relationship agreed by the protocol may be that one condition corresponds to a plurality of measurement objects.
In one possible implementation manner, in a case that one condition corresponds to one measurement object, the first terminal may perform measurement with respect to the first measurement object when it is determined that the condition corresponding to the first measurement object is satisfied.
In another possible implementation manner, in a case where the plurality of conditions correspond to one measurement object, the first terminal may perform measurement with respect to the second measurement object when it is determined that at least some of the plurality of conditions corresponding to the second measurement object are satisfied.
For example, the second measurement object is a cell identifier, and the corresponding multiple conditions include: finding that the signal intensity of the signal is smaller than a preset signal threshold; the first terminal and the second terminal are in different areas.
The first terminal may measure the cell identity in a different area than the second terminal.
Or the first terminal may measure the cell identifier when the signal strength of the discovery signal is smaller than a preset signal threshold and the first terminal is in a different area from the second terminal.
In another possible implementation manner, in the case that one condition corresponds to a plurality of measurement objects, the first terminal may perform measurement on a plurality of third measurement objects corresponding to the condition when the condition is satisfied.
In the above embodiment, the first terminal may perform measurement with respect to the corresponding measurement object when the condition is satisfied based on the correspondence between the condition and the measurement object. The method and the device can avoid continuous cell measurement when the first terminal is in an area without network coverage, and achieve the purpose of saving the electric quantity of the terminal.
