Embodiment Construction

[0032] In the 5G system, paging messages are also transmitted by broadcast. In the multi-beam scenario, due to the mobility of the user terminal, the base station usually cannot know the optimal downlink beam where the user terminal in the idle state and inactive state resides, so the base station cannot be in the corresponding beam of the user terminal. To send a paging message on the optimal downlink beam, the same paging message can only be transmitted on all beams by beam scanning. When there are many user terminals to be paged and the number of beams configured by the base station is large, the downlink overhead occupied by broadcasting and transmitting the paging signal through the method of beam scanning is relatively large.

[0033]In order to reduce the overhead of downlink resources, one method is to send paging through the mechanism of paging indication, and group the user terminals in the inactive state and idle state in the system into paging groups, and the base ...

Abstract

A user terminal and a paging message transmission method thereof, and a computer-readable storage medium, wherein the paging message transmission method includes: receiving a downlink control message issued by a base station, and obtaining a paging indication from the downlink control message; when detecting When there is a paged user terminal in the corresponding paging group, determine whether to perform the uplink random access process, including: when the uplink random access process has been performed in the previous paging cycle, and the optimal downlink is detected When the beam does not change, it is determined not to perform the uplink random access process; and the paging message delivered by the base station is received. The above solution can reduce uplink resource overhead and reduce the probability of uplink access collision.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and in particular, to a user terminal, a paging message transmission method thereof, and a computer-readable storage medium. Background technique [0002] In a Long Term Evolution (LTE) system, when sending downlink data to a user terminal in an idle (IDLE) state, all Tracking Areas (Tracking Areas) registered with the user by the Mobility Management Entity (MME) , all base stations (eNBs) in TA) send a paging message. After receiving the paging message, the user terminal in the idle state will initiate an uplink random access radio resource control (Radio Resource Control, RRC) connection establishment process to receive the call if it finds itself being called. If it finds itself not being called, the user terminal discards the received paging message and enters a dormant state. [0003] In the 5G system, paging messages are also transmitted by broadcast. In a ...
