Description

RELATED APPLICATION This application claims priority to PCT Application No. PCT/CN2020/075150, filed on Feb. 13, 2020. FIELD Embodiments of the present disclosure generally relate to the field of telecommunication and in particular, to a device, method, apparatus and computer readable medium of dynamic signaling for a measurement gap. BACKGROUND As mentioned above, a configuration of measurement gap may be required for a gap assisted measurement performed at a terminal device depending on the capability of the terminal device. In general, the measurement gap may be referred to as a gap in which a terminal device will interrupt the data transmission to serving cell and perform the signal measurement to target cell. The 5G Radio Access Network (RAN) decided to introduce the capability signalling “NeedForGap” in Release 16 to improve the data transmission efficiency. The network will configure measurement gap for a terminal device only in the case that the terminal device reports NeedForGap=true, otherwise no measurement gap will be configured to the terminal device. The motivation to introduce this dynamic NeedForGap signaling procedure is that, whether the terminal device could perform gapless measurement not only depends on the current band combination but also some parameters that define the occupation of some band resource. In a conventional way, the terminal device may have to set NeedForGap=TRUE in most cases unless this terminal device can support gapless measurement for all kinds of Layer 1 (L1) configuration in the band combination.
