Description

Information transmission and reception method, device, equipment and storage medium

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, a device, and a storage medium for transmitting and receiving information.

Background

Network power saving (Network energy saving) is one of the possible issues for R18. The issue is how to perform energy saving of base stations and networks. In this issue, one possible way to save power is to turn off part of the beam or carrier of the base station. For example, some beams/carriers may cover little or no User Equipment (UE), and it may be considered to turn off the beams/carriers.

If a beam or carrier is turned off, UEs under the beam or carrier coverage need to switch/reselect to other beams/carriers, or other cells. However, abrupt beam or carrier switching off may cause UE handover/reselection to be not timely, resulting in communication interruption, paging loss, paging delay, or the like.
