Inter-cell interference coordination (ICIC) is considered as the most promising approach for LTE to mitigate inter-cell interference. One important approach for ICIC is Soft Frequency Reuse (SFR). However, the analytical model of SFR has not been fully studied yet as cell-center mobile platforms occupying channels from the center band or the edge band were not distinguished. We derive a new analytical...
The number of users accepted by a cell is limited by the total received interference power at base station transceiver in code-division multiple access (CDMA) system. In this paper, we propose a received power based call admission control (MSRP-CAC) scheme supporting multi-class services for uplink, which determines the admission of multi-class services via presetting power allocation ratios. The...
The proposed Grade of Service based Call Admission Control (GoS-CAC) algorithm in the next generation mobile communications system operates a threshold comparison, which integrates many factors that affect the decision accuracy of a CAC scheme such as system traffic loads, quality of service (QoS) requirements, channel quality, interference level, system GoS and user handoff, etc. The GoS-CAC algorithm...
