Abstract
Official abstract text for this publication.
A user equipment (UE) of re-organizing a timing advance group (TAG) is provided. The UE comprises: a receiving unit for receiving, from a serving base station, secondary serving cell (SCell) configuration information which includes a first field and a second field, the first field including an ScellIndex of an SCell to indicate a removal of the SCell, the second field including at least one of the ScellIndex to indicate an addition of the SCell and a TAG ID indicating a TAG of the SCell, and a radio resource control (RRC) processing unit for performing the addition of the SCell after performing the removal of the SCell from one or more SCells configured in the UE, and for reorganizing the TAG by including the SCell in the TAG.
First claim
Opening claim text (preview).
What is claimed is: 1. A user equipment (UE) of re-organizing a timing advance group (TAG) that is a group of serving cells with an uplink configured that use the same timing reference cell and the same timing advance value, the UE comprising: a receiving unit for receiving, from a serving base station, secondary serving cell (SCell) configuration information which includes a first field and a second field, the first field including an ScellIndex of an SCell to indicate a removal…
