Embodiment 1
[0122] The network can issue indication information, which indicates whether the UE can perform serving cell measurement on other SSB frequencies, so that if the UE switches to a BWP that does not include SSB#1, it can also use other SSBs for measurement.
[0123] If the SSB at the frequency location includes the same second SSB transmitted by the base station as the transmission SSB #1, then the UE may perform serving cell measurement based on the second SSB, or further include intra-frequency neighbor cell measurement of the frequency.
[0124] Further, the network may also indicate whether the same-frequency neighbor cell measurement can be performed on the frequency based on the SSB through the indication information, and if the indication information is received, the UE may perform the same-frequency neighbor cell measurement on the frequency.
[0125] Further, the indication information may be transmitted through high-layer signaling.
Embodiment 2
[0127] The network may use downlink control information (Downlink Control Information, DCI) to indicate whether the UE can perform serving cell measurement and / or intra-frequency neighbor cell measurement on the frequency.
[0128] For example, in the DCI indicating to perform BWP handover, it also indicates to perform serving cell measurement and / or intra-frequency neighbor cell measurement.
Embodiment 3
[0130] The network indicates the measurement of the serving cell and / or the measurement of the neighboring cells of the same frequency in a non-explicit (implicit) way. In the current version 15 (Rel-15) protocol, it does not support the quasi-shared SSB of different frequencies. address (Quasi Co-Loacted, QCL) instructions.
[0131] Furthermore, the network can indicate the QCL relationship of SSBs at different frequency positions. If the UE receives the QCL indications of SSBs at two frequency positions, the UE can use the measurement results of SSBs at any one of the two frequencies as the link of the serving cell. Road measurement results. Further, the UE may perform intra-frequency measurement on a frequency.

Abstract
Embodiments of the present invention provide a measurement method, a measurement indication method, and a device. The method includes: receiving indication information, the indication information indicating whether the terminal can perform measurements at one or more second SSBs; wherein, the frequency position of the second SSB is different from the frequency position of the first SSB, and the The first SSB is the SSB used for serving cell measurement. In the embodiment of the present invention, the terminal can use the non-cell defining SSB in the BWP currently receiving downlink to perform RRM measurement, which reduces the interruption of data transmission and increases the flexibility of the terminal's measurement behavior.
Description
technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a measurement method, a measurement indication method, and a device. Background technique [0002] When the bandwidth of the downlink active bandwidth part (Bandwidth part, BWP) received by the UE does not include the terminal (such as the cell defining synchronization signal block (Synchronization Signal and PBCH block, SSB) of the user equipment (User Equipment, UE) In this case, the terminal cannot perform measurement on the current BWP, and needs to jump to the frequency where the SSB is located for measurement. This will cause frequent readjustment of the terminal receiving frequency, resulting in discontinuous downlink reception. Contents of the invention [0003] An object of the embodiments of the present invention is to provide a measurement method, a measurement indication method, and a device to solve the problem that the termin...
