Performance Estimation of the Forward Link in a Macrocell/Microcell Hierarchical Cellular System Using Code Division Multiple Access∗

چکیده
In order to serve traffic hot spots, the hierarchical cellular systems or the hybrid TDMA/CDMA have been proposed, recently. In order to depress the multi-user interference and increase capacity, the forward link power control strategy is adopted in the macrocell/microcell hierarchical cellular system using code division multiple access (CDMA). Its effects are estimated in this paper. Especially, the impact of τ -th distance power control laws on the forward link outage probability and capacity plane for the hierarchical cellular system are investigated. The coverage area user capacity of the overlaid macrocell/microcell cellular system is obtained. The numerical results and discussions with previous published results are presented in detail. key words: hierarchical system, forward link, power control,

Capacity analysis of spectrally overlaid macro/microcellular CDMA systems supporting multiple types of traffic
The reverse link capacity of a spectrally overlaid macrocell/microcell cellular code-division multiple-access system supporting various types of traffic is analyzed. Several narrow-band subsystems are overlaid with a wide-band subsystem in macrocells, while in a microcell a single narrow-band subsystem is operated with the same spectrum as one of the macrocell narrow-band subsystems. Using a ty...
متن کاملForward-link soft-handoff in CDMA with multiple-antenna selection and fast joint power control
We consider forward-link soft-handoff with multiple antenna selection and fast joint power control at high data rates in a cellular code-division multiple-access network, where signals are directed to a mobile station (MS) from antennas located at the same or different base stations. The total power transmitted to any mobile is divided among the active antennas selected according to the momenta...
متن کاملMacrocell/microcell selection schemes based on a new velocity estimation in multitier cellular system
The Intermational Mobile Telecommunications IMT-2000 system uses a microcell concept to provide multimedia services and to support increasing number of users. However, in a microcell system, the number of handoffs is greatly increased. To solve this problem, a multitier cellular structure is proposed, in which high-speed mobile terminals (MTs) are serviced in macrocell and low-speed MTs are ser...
متن کاملHandoff analysis of the hierarchical cellular system
As mobile telephone traffic demands increase in the future, interest in cellular systems with a hierarchical structure will grow. Hierarchical cellular system can provide high system capacity, efficient channel utilization, and an inherent load-balancing capability. In this type of system, calls blocked in a microcell flow over to a macrocell which is superimposed on a number of microcells. Whe...
متن کاملModeling Asymmetric Slot Allocation for Mobile Multimedia Services in Microcell TDD Employing FDD Uplink as Macrocell
This paper introduces an analytical approach which is provided to calculate the downlink and uplink capacities of the time division duplex (TDD) system utilizing the underused frequency division duplex (FDD) uplink which shares the same frequency band. Then the ratio of downlink and uplink slots in one frame is adjusted, so as to prevent the radio resource waste due to asymmetric traffic charac...
