Description

Measurement method, terminal and network side equipment
Technical Field
The present invention relates to the field of wireless communication technologies, and in particular, to a measurement method, a terminal, and a network side device.
Background
For the same-frequency measurement and the different-frequency measurement, the measurement behaviors of a terminal (User Equipment, abbreviated as UE) are different. Common-frequency measurement, generally without measurement interval (MG); inter-frequency measurements, typically require a measurement interval. And in the measurement interval, the terminal modulates the frequency to a target frequency point for measurement, the terminal interrupts the data transmission with the service cell during the period, and after the target frequency point measurement is completed, the terminal modulates the frequency to the original frequency point to continue the data transmission with the service cell.
The frequency domain Resource of a Channel State Information Reference Signal (CSI-RS) is configured by the number of occupied Resource Blocks (RBs) and the frequency domain starting position, the CSI-RS is distributed in the frequency range, and the CSI-RS occupies a plurality of Resource Elements (REs) in each RB. The CSI-RS Resource configuration used for Radio Resource Management (RRM) measurement in the neighboring cell and the active Part Bandwidth (BWP) of the UE have various position relationships in the frequency domain, and different frequency domain position relationships may affect whether a measurement interval and/or measurement performance is needed. For example, referring to fig. 1, CSI-RS bandwidth configuration 1 completely overlaps with the active bandwidth of the UE, and the terminal may not need a measurement interval (MG) to complete the corresponding measurement; the CSI-RS bandwidth configuration 5 is completely not overlapped with the activation bandwidth of the UE, and the terminal can complete corresponding measurement only by a measurement interval (MG); the CSI-RS bandwidth configuration 2-3 cannot be completely covered by the activated bandwidth of the UE, if the terminal measures based on complete CSI-RS frequency domain resources, a measurement interval may need to be adopted, data loss (data loss) is introduced, the system throughput rate is reduced, and if the terminal measures based on received partial CSI-RS resources, the measurement performance is affected due to the reduction of measurement resources. That is, at present, for CSI-RS whose bandwidth is completely covered by the terminal-activated BWP and CSI-RS whose bandwidth does not overlap with the terminal-activated BWP, whether measurement intervals are needed and measurement performance are both determined, but for the case where the CSI-RS bandwidth overlaps with the terminal-activated BWP, it is not clear at present.
