Abstract

This paper studies paging operation when carrier aggregation (CA) is adopted in LTE-A system. A numerical analysis is provided and shows signaling overhead would increase significantly if paging is not properly controlled under CA. To overcome the problem, efficient paging controls are proposed while adaptive paging configurations on different component carrier are able to resist excessive overhead. In additional, a hierarchical paging message delivery scheme is jointly controlled to take paging latency into account. The results demonstrate that our proposal can work well in different environments with minimum changes in 3GPP specification.
