Embodiment Construction

[0023] In the LTE system, the Paging message can send a call request to the UE in the RRC_IDLE state. Paging supports Discontinuous Reception (DRX), so that the UE in the RRC_IDLE state only "wakes up" on a specific subframe (called PO) of a specific frame (called PF) within its Paging cycle to monitor The PDCCH scrambled by the P-RNTI can be kept in a "sleep" state at other times, so that power consumption can be reduced and the battery life of the UE can be improved.

[0024] PO (Paging Occasion) is a subframe, on which there may be a PDCCH scrambled with P-RNTI and indicating a Paging message. When DRX is used, the UE only needs to detect 1 PO in each DRX cycle, that is, corresponding to each UE, only 1 subframe can be used to send Paging in each Paging cycle. DRX cycle and Paging cycle are the same concept.

[0025] PF (Paging Frame) is a wireless frame, which may contain one or more POs. The paging frame position PF is a system frame satisfying the following formula (1...

Abstract

The embodiment of the invention discloses a method and device for determining a reconfiguration paging position, a terminal and a storage medium. The method comprises the steps: determining a paging frame PF; determining an initial time slot number corresponding to a paging opportunity PO in each PF according to the synchronization signal block number / the number L of the physical broadcast channelblocks and the configuration parameters of the search space; and determining L search spaces as the positions of the PO according to the start time slot number and the configuration parameters of thesearch spaces.

Description

technical field [0001] Embodiments of the present invention relate to, but are not limited to, communication technologies, and in particular, relate to a method, device, terminal, and storage medium for determining a reconfigured paging location. Background technique [0002] In the fifth generation (5 th Generation, 5G) in the new radio (New Radio, NR) system, paging (paging) downlink control information (Downlink Control Information, DCI) position default and remaining minimum system information (Remaining Minimum System Information, RMSI) search space ( search space) in the same location, but through the 3rd Generation Partnership Project (3 rd Generation Partnership Project, 3GPP) discussion, in this case the physical downlink control channel (Physical Downlink Control Channel, PDCCH) and physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) capacity is limited, so consider RMSI reconfiguration search The case of the search space. When the RMSI ...
