Embodiment Construction

[0114] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0115] In order to better understand the present invention, first a brief introduction is made to the SS Block (SynchronicSignal Block, synchronous signal block) involved in the embodiment of the present invention. SS Block is used by NR system to complete broadcast and synchronization. Each SS Block contains PSS (Primary Synchronization Signal, primary synchronization signal), PBCH (Physical Broadcast Channel, physical broadcast channel) and SSS (Secondary Synchronization Signal, secondary synchronization signal) channel. In order to meet the beam scanning requirements of NR using high-frequency spectrum, SS Block itself performs beam scanning, but the original intention of designing SS Block is to solve the synchronization and system broadcasting probl...

Abstract

The invention provides a paging monitoring method and a terminal, relates to the field of communication, and solves the problem that a paging mechanism in the prior art cannot realize beam scanning ofa terminal side in a high-frequency scene. The method comprises the following steps: before a PO to which a terminal belongs appears, carrying out beam scanning in an SS Block window closest to the PO to obtain a receiving beam; And monitoring the paging message vector in the PO through the receiving beam. According to the scheme of the invention, the terminal side multiplexes the scanning periodof the SS Block to carry out the beam selection process of the terminal side; Therefore, the terminal can determine the received wave beam conveniently and complete paging monitoring according to thedetermined wave beam. The problem that an existing paging mechanism cannot achieve terminal side beam scanning in a high-frequency scene is solved, and due to the fact that the receiving beam scanning work of the terminal is completed together with the SS block scanning process of the system, a new terminal scanning period is not introduced to the system, and the system overhead is reduced.

Description

technical field [0001] The invention relates to the communication field, in particular to a paging monitoring method and terminal. Background technique [0002] In NR, due to the high-frequency transmission, the network side needs to use the beam scanning method for paging the terminal; and for the terminal, the terminal can also support the beam scanning operation. No matter in the LTE or NR system, each terminal will monitor a paging moment in a paging cycle. The difference is that there is no beam scanning problem in the LTE system. The duration of a paging moment is the cycle of a subframe ; In the NR system, the duration of a paging moment is the occupancy time of several subframes or multiple symbols, because the beam scanning operation on the network side is reflected in each paging moment, in each paging During the time duration, the network side needs to send paging messages in multiple directions respectively. [0003] The paging mechanism of the existing LTE sys...
