A large number of phone calls and data services will take place in indoor environments. In Long Term Evolution (LTE), femtocell, as a home base station for indoor coverage extension and wideband data service, has recently gained significant interests from operators and consumers. Since femtocell is frequently turned on and off by a personal owner, not by a network operator, one of the key issues is that femtocell should be identified autonomously without system information to support handover from macrocell to femtocell. In this paper, we propose a dynamic reservation scheme of Physical Cell Identities (PCI) for 3GPP LTE femtocell systems. There are several reserving types, and each type reserves a different number of PCIs for femtocell. The transition among the types depends on the deployed number of femtocells, or the number of PCI confusion events. Accordingly, flexible use of PCIs can decrease PCI confusion. This reduces searching time for femtocell, and it is helpful for the quick handover from macrocell to femtocell. Simulation results show that our proposed scheme reduces average delay for identifying detected cells, and increases network capacity within equal delay constraints.

“…LTE was initially planned by NTT DoCoMo of Japan in November, 2004 as the international standard [2]. Today different cellular and wireless firms want a major increase in capacity which has to be carried in coming years beyond fourth generation of wireless standards in Long Term Evolution (4GLTE) [3] or 3GPP Long Term Evolution [4].…”

Abstract-The area of mobile communication is fast developing as a result of the technological advancement in the field of mobile and wireless communication. Obviously, 3G was once acclaimed as a recent technology in the field of wireless and mobile communication until the arrival of 4GLTE. The quest for a faster speed, lower latency, better QoS and ability to interoperate with all existing network are some of the factors that brought up the emergence of 4GLTE network. In this paper we provide an overview of all network generations from the first generation to the fourth generation as well as the differentiating features that supports the superiority of the 4GLTE network to the 3G network are well stated. We use self-analytical tools like bar charts to compare the features of 4GLTE and 3G networks. The concluding part of this paper presents improvements needed in 4GLTE.Index Terms-3G, 4GLTE, OFDMA, comparison of 3G and 4GLTE networks.
