Problems solved by technology

[0003] In the idle (IDLE) state, for the purpose of saving UE power consumption, the sleeping UE will turn off the high-precision clock and only use the low-precision clock for timing processing. Therefore, when waking up from sleep to receive paging, there will be certain Time offset and frequency offset, if the time offset / frequency offset is not corrected first, then in extreme cases, the UE may not receive paging, and the phenomenon of missed paging may occur

Embodiment Construction

[0024] As mentioned in the background art, in the prior art, paging may not be received due to time frequency and frequency offset, and paging missed phenomenon may occur.

[0025] In NR technology, usually, SSB can be used for pre-synchronization to eliminate time offset and / or frequency offset. Specifically, in the prior art, the strongest SSB measured by the previous serving cell can be used as the SSB used for pre-synchronization when waking up from sleep next time, and the time offset and / or frequency offset can be adjusted according to the measurement result of the SSB , and then receive paging, and then receive and measure other SSBs configured by the serving cell.

[0026] figure 1 It is a schematic flowchart of a paging receiving method in the prior art. refer to figure 1 , before receiving paging, the UE first receives the strongest SSB of the serving cell for pre-synchronization, and completes time offset and frequency offset correction; after that, it receives p...

Abstract

Provided are a paging receiving method and device, a storage medium and a terminal. The paging receiving method comprises the steps: measuring a plurality of SSBs of a serving cell to determine the strongest SSB with the best signal quality among the plurality of SSBs; calculating a paging time-frequency position associated with the strongest SSB; and receiving paging at the paging time-frequencyposition. According to the invention, paging can be received at a time-frequency position with higher accuracy, the decoding performance of paging is ensured, and the power consumption is saved.

Description

technical field [0001] The present invention relates to the technical field of communications, and in particular to a paging receiving method and device, a storage medium, and a terminal. Background technique [0002] In the Fifth-Generation mobile communications (5G for short) New Radio (NR for short, also known as NR) system, the difference between the time position of paging and the previous communication system is that, in addition to In addition to being different in the basic configuration, it is also related to the position of an index (index) of a synchronization signal block (Synchronization Signal and physical broadcast channel Block, SSB for short). As the position changes, the strength of each beam (beam) of a user equipment (User Equipment, UE for short) may also change. Therefore, for the UE, measuring each beam of a serving cell is also a necessary work. [0003] In the idle (IDLE) state, for the purpose of saving UE power consumption, the sleeping UE will tu...
