“…For instance, Dunkin et al (1998) introduce besides forbidden combinations for pairs, forbidden combinations of frequencies for triples of vertices. Kalvenes et al (2005) present a model featuring antenna location and user allocation in addition to the assignment frequencies. Objective is to maximize the total revenue generated by the cellular network designed.…”

Wireless communication is used in many different situations such as mobile telephony, radio and TV broadcasting, satellite communication, wireless LANs, and military operations. In each of these situations a frequency assignment problem arises with application specific characteristics. Researchers have developed different modeling ideas for each of the features of the problem, such as the handling of interference among radio signals, the availability of frequencies, and the optimization criterion.This survey gives an overview of the models and methods that the literature provides on the topic. We present a broad description of the practical settings in which frequency assignment is applied. We also present a classification of the different models and formulations described in the literature, such that the common features of the models are emphasized. The solution methods are divided in two parts. Optimization and lower bounding techniques on the one hand, and heuristic search techniques on the other hand. The literature is classified according to the used methods. Again, we emphasize the common features, used in the different papers. The quality of the solution methods is compared, whenever possible, on publicly available benchmark instances. This is an updated version of a paper that appeared in 4OR 1, 261-317, 2003.

“…The minimum SIR thresholds are fixed to 0.03125 for both the UL and DL. 4 The exact numerical values of these parameters have been obtained from [22] and have no special significance. Orthogonality factor k = 0.06 [21] and the noise variances at the BS and mobile handset are taken to be 4.…”

Abstract-In this paper, we propose an optimization framework for the design of CDMA-based cellular networks. The framework incorporates both the uplink (UL) and downlink (DL) quality of service (QoS) constraints to determine the base station (BS) selection and base-station-to-mobileuser association. The framework also allows the network planner the flexibility to trade-off the net profit with the total transmission power. The framework also allows the network operator to examine the effect of varying number of service classes and frequency reuse factor. Representative numerical results of the optimization are given.

“…For 2G systems, many research efforts [7][8][9][10] consider two-phase BS deployment. In phase 1, they select a set of candidate locations to place macrocell BSs in order to meet the given capacity demand such that the system cost can be reduced.…”

Efficient eNB deployment strategy for heterogeneous cells in 4G LTE systems

a b s t r a c tBase station deployment is an important issue in cellular communication systems because it determines the cost to construct and maintain a system and also the service quality to users. Conventional 2G and 3G systems assume that base stations are identical in the sense that they have the similar coverage range. For 4G systems, LTE introduces the concept of heterogeneous base stations (also called eNBs), which supports different sizes of coverage range. Given the user distribution and demands in a service area, the problem of deploying heterogeneous eNBs is NP-hard. Therefore, we propose a four-stage eNB deployment strategy to efficiently solve the problem. Our strategy first employs a geometric approach to provide the basic coverage to the service area. Then, it adaptively adjusts the cell range to satisfy the user demands under the power and bandwidth constraints on each eNB. Simulation results verify that the proposed strategy not only significantly saves the system cost, but also reduces the power consumption while balances the traffic loads of eNBs.
