“…The performance of JT CoMP has been extensively studied in the literature. For example, in [4], the outage probability of joint processing CoMP when maximum ratio transmission is used at the TPs was presented. Similarly, the macro diversity gain of CoMP in dense cellular networks was investigated in [5] of TPs form a random network topology.…”

Joint transmission (JT)-based Coordinated Multipoint (CoMP) systems achieve high performance gains by allowing full coordination among multiple cells, transforming unwanted intercell interference into useful signal power. In this paper, we present an analytical model to perform adaptive modulation for a typical JT CoMP system, consisting of three transmission points, under a target bit error rate (BER) constraint. Probability density functions of the signal-to-interference-plus-noise ratio (SINR) are derived for different JT CoMP schemes, and based on them, closed-form expressions for the average spectral efficiency (ASE) are obtained when adopting continuous-rate adaptive modulation. The study of ASE is also extended for the case of discrete-rate modulations, where the performance comparison of different practical quantized modulation schemes is carried out. Index Terms-Average spectral efficiency (ASE), continuous-rate adaptive modulation, Coordinated Multipoint (CoMP), discrete-rate adaptive modulation, joint transmission (JT).

“…In CoMP, these improvements are achieved by coordinating transmissions, scheduling decisions, or beam patterns among BSs. In [11], Cheikh et al derive the outage probability in a joint processing CoMP scenario. In contrast to CoMP, which enables interference mitigation and targets throughput improvement, we investigate the capability of providing high availability by a joint transmission over various links at different carrier frequencies.…”

Future cellular networks have to meet enormous, unprecedented, and multifaceted requirements, such as high availability and low latency, in order to provide service to new applications in, e.g., vehicular communication, smart grids, and industrial automation. Such applications often demand a temporal availability of six nines or higher. In this work, we investigate how high availability can be achieved in wireless networks. To elaborate, we focus on the joint availability of powercontrolled Rayleigh-fading links while using selection combining. By applying a basic availability model for uncorrelated links, we determine whether it is more efficient in terms of power to utilize multiple links in parallel rather than boosting the power of a stand-alone link. The results reveal that, for high availability, it can actually be beneficial to use multiple links in parallel. For instance, an availability of 1 − 10 −12 is achieved with 100 dB less power when power is shared among multiple links. Depending upon the availability desired, an optimal number of parallel links in terms of power consumption exists. Additionally, we extend the availability model to correlated links and investigate the performance degradation due to correlation.Globecom 2014 Workshop -Ultra-Low Latency and Ultra-High Reliability in Wireless Communications 978-1-4799-7470-2/14/$31.00 ©2014 IEEE

“…In [18] in order to cover the coverage area of the switched off BS's and to compensate the loss due to increased distance between the user equipment (U E) and the BS, CoMP transmission by the neighbouring BS's surrounding the switched off cell, is considered. However the effect of interference on extending the signal to the users at worst case locations has not been taken into account.…”

Existing cellular networks remain operational throughout the year irrespective of traffic. The usage of Coordinated Multipoint (CoMP) transmission to provide service in the coverage area of a switched off base station (BS) during off-peak traffic hours has been investigated in this work. The switching off of a BS reduces its energy consumption to zero, however to cover the switched off BS coverage area by neighbouring BS’s, CoMP transmission causes an increase in energy consumption of the neighbouring BS’s. With increasing the number of base stations taking part in CoMP transmission the power consumption of CoMP base stations and site air conditioning unit increases. Results show that the aggressive usage of CoMP is not feasible in most of the twelve switching modes investigated. From the Energy Efficiency Ratio the most energy efficient switching mode is identified. It is then applied to part of a cellular network and the amount of power saving and Carbon Dioxide equivalent (CO2e) is determined. It is found that within a network of 42 cells 7.26% power can be saved by switching off seven base stations during off-peak traffic hours.
