Description

An information transmission and reception method, device, equipment and storage medium

technical field

The present disclosure relates to the technical field of wireless communication, and in particular, to an information transmission and reception method, device, device, and storage medium.

Background technique

Network energy saving is one of the possible topics of R18. This topic studies how to save energy in base stations and networks. In this issue, a possible energy saving method is to turn off some beams or carriers of the base station. For example, if the number of user equipment (User Equipment, UE) covered by certain beams/carriers is small or none, it may be considered to turn off the beams/carriers.

If a beam or carrier is turned off, UEs covered by the beam or carrier need to switch/reselect to other beams/carriers, or other cells. However, turning off the beam or the carrier suddenly may cause UE handover/reselection to be untimely, resulting in communication interruption, paging loss or paging delay, etc.
