Problems solved by technology

To handle such scenarios, existing mobility control methods are inefficient and thus cause long outage times and even high loss rates

Abstract

The embodiments disclose methods and devices for mobility control of UEs in a HetNet with multiple frequency carriers. In the methods, intra-frequency measurement and inter-frequency measurement are performed sequentially for determining a target cell to handover to.

Description

technical field [0001] The present technology relates generally to radio communications, and more particularly to methods and apparatuses for mobility management. Background technique [0002] In Long Term Evolution-Advanced (LTE-A), which is a next-generation cellular communication standard discussed in the 3rd Generation Partnership Project (3GPP), an introduced technology called Carrier Aggregation (CA) has been studied. Carrier aggregation is a technology that forms a communication channel between a user equipment (UE) and a base station (BS or evolved Node B (eNB)) by, for example, aggregating multiple frequency bands supported in LTE, and thus improves communication throughput. Each frequency band included in one communication channel through carrier aggregation is called a component carrier (CC). The bandwidths of frequency bands available in LTE are 1.4 MHz, 3.0 MHz, 5.0 MHz, 10 MHz, 15 MHz, and 20 MHz. Accordingly, if five 20 MHz bands are aggregated as constitue...
