In addition, while measuring the uplink beam, the impact of uplink interference is also taken into account, thereby making the accuracy of the determined third measurement result higher and improving the accuracy of cell switching.

[0640] FIG7 is a flow chart of a measurement method according to an embodiment of the present disclosure. As shown in FIG7 , the embodiment of the present disclosure relates to a measurement method, which can be executed by a terminal and may include:
[0641] Step S7101: Send an SRS for uplink beam measurement.
[0642] In some embodiments, the TA value sent by the SRS adopts the TA of the serving cell.
[0643] In other embodiments, in order to prevent a certain candidate cell from having a too long protection time and a too long transmission interruption time, the average of the TAs of the candidate cells with the same frequency may be used to transmit the SRS.
[0644] In one implementation, the TA value of each candidate cell may be indicated to the terminal, and the TA of each candidate cell may be maintained in advance; or the TA value for transmitting the SRS may be indicated to the terminal.
[0645] In some embodiments, in order to avoid affecting other transmissions in the serving cell, an additional guard time is required before transmitting the SRS. The guard time may be specified by a protocol or configured by the network.
[0646] In some embodiments, for candidate cells with different frequencies than the serving cell, SRSs for uplink beam measurement can be sent separately for these candidate cells. Because a terminal may not be able to transmit SRSs on other frequency bands while maintaining communication with the serving cell, a transmission window / gap configuration for SRSs on other frequency bands is being considered. The window / gap can be configured by the network or specified by the protocol. During the window / gap, the terminal does not need to communicate with the serving cell.
[0647] In some embodiments, the terminal may transmit an SRS for interference measurement.
[0648] In a possible implementation, no uplink data is sent in the time-frequency resources corresponding to the SRS used for interference measurement, so that the candidate cell measures interference at the corresponding time-frequency position.
[0649] In some embodiments, the terminal may receive configuration information sent by a serving cell, where the configuration information may be configuring SRS resources for the terminal.
[0650] In some embodiments, the SRS resources configured for the terminal for uplink beam measurement include at least one of the following: time-frequency resources, port configuration, frequency position, and TA.
[0651] In some embodiments, the serving cell may configure SRS resources for uplink beam measurement for the terminal, including: time-frequency resources, port configuration, and frequency position.
[0652] In some embodiments, the serving cell may inform the candidate cells that need to perform uplink beam measurement based on the SRS resources configured for uplink beam measurement.
[0653] In some embodiments, the serving cell may configure SRS resources (interference measurement, SRS-IM) for the terminal for uplink interference measurement.
[0654] In some embodiments, the SRS resources used for uplink interference measurement may include: period and offset, symbol position, frequency band, and carrier position.
[0655] FIG8 is a flow chart of a measurement method according to an embodiment of the present disclosure. As shown in FIG8 , the embodiment of the present disclosure relates to a measurement method, which can be performed by a first network device and can include:
[0656] Step S8101: Perform beam measurement according to configuration information.
[0657] In some embodiments, the first network device may measure SRS-RSRP or SRS-SINR.
[0658] In one implementation, if the SRS resource is associated with an SRS-IM configuration for interference measurement, the SRS-SINR is measured.
[0659] In some embodiments, when measuring SINR, uplink interference is measured according to SRS-IM.
[0660] In another implementation, if the SRS resource is not associated with an SRS-IM configuration for interference measurement, SRS-RSRP is measured.
[0661] In some embodiments, since the terminal does not send the SRS completely according to the TA value of the candidate cell, the sent SRS cannot be aligned with the timing of other uplink transmissions of the candidate cell. In order to prevent interference with other uplink transmissions of the candidate cell, the candidate cell needs to determine a guard time, during which there will be no uplink transmissions from other users and the candidate cell.
[0662] In some embodiments, the specific length of the guard time is determined by the candidate cell. If the difference between the arrival timing and the timing of the candidate cell is less than the CP length, the guard time may not be introduced.
[0663] In some embodiments, the first network device may receive configuration information sent by the serving cell, ie, SRS resources.
[0664] In some embodiments, the configuration information includes at least the time-frequency resources of the SRS and the TA value used when the SRS is sent.
[0665] In some embodiments, the SRS used for uplink interference measurement and the SRS used for uplink beam measurement may be correlated.
[0666] In some embodiments, after completing the uplink beam measurement, the candidate cell may feed back the measurement result to the serving cell.
