“…The Greedy Clustering, summarized in Algorithm 4, consists in initializing the cluster of BSs as the set of best server cells of group users (step 3). Then, at every iteration and if possible, we add to the cluster the BS that decreases at most the objective function (13) (steps [5][6][7][8][9][10][11][12]. If there is no such BS (step 13) or if we have reached the whole set of cells (step 16), we return the current cluster (steps 17 or 14).…”

“…This technique is called Single-Cell Point-To-Multipoint (SC-PTM) by 3GPP [6] and has the advantage of maximizing the capacity of the network at the price of a degraded SINR for the group users, especially those at cell edge owing to the higher ICI compared to MBSFN. More MCC group calls can be served at the price of a degraded coverage reliability [7].…”

Reliable group video call is one of the main services offered by future Mission-Critical Communications (MCC). To support its requirements, coordinated multi-point transmission in multi-cell environments is an attractive feature for MCC over Multimedia Broadcast Multicast Services owing to its potential for coverage improvement and multicast transmission. In such a scheme, full cooperation among all cells of an area achieves the highest cooperative gain, but has stringent impact on system capacity. A trade-off in the cluster's size of serving cells thus arises between high Signal to Interference plus Noise Ratio (SINR) and network capacity. In this paper, we formulate an optimization problem to maintain an acceptable system blocking probability, while maximizing the average SINR of the multicast group users. For every multicast group to be served, a dynamic cluster of cells is selected based on the minimization of a submodular function that takes into account the traffic in every cell through some weights and the average SINR achieved by the group users. Traffic weights are then optimized using a modified Nelder-Mead simplex method with the objective of tracking a blocking probability threshold. The proposed clustering scheme is compared to full cooperation and to Single-Cell Point-To-Multipoint (SC-PTM) schemes. Results show that dynamic clustering offers the best trade-off between coverage and capacity for MCC.

“…At last, they consider at most 20 UEs per cell, which is low for MC Scenarios in massive events. The work in [4] compares MBSFN, SC-PTM and UC in terms of radio quality, system spectral efficiency and cell coverage. Their study considers 4 UE/cell in most simulations and a BS density of ∼0.31 BS/km 2 with omnidirectional antennas.…”

Mission Critical Communication (MCC) Services are currently provided through secure and reliable Professional Mobile Radio (PMR) dedicated networks. These services include voice, data and video delivery. During an emergency, timely access to video streaming can increase situational awareness and enhance life-saving operations. Therefore, to improve the capabilities of PMR networks and benefit from the advantages of mutualization, standard cellular technologies based on 4G and 5G were adopted for MCC. In particular, the evolved Multimedia Broadcast Multicast Service (eMBMS) is suitable for the transmission of group communication services. There are two broadcast transmission modes proposed in eMBMS: Multicast Broadcast Single Frequency Network (MBSFN) and Single-Cell Point-to-Multipoint (SC-PTM). In this paper, we compare MBSFN, SC-PTM and Unicast (UC) in Mission Critical (MC) scenarios from a resource use perspective. More precisely, we calculate the system spectral efficiency in each mode and estimate the number of users per square kilometer demanding the same MC service from which MBSFN and SC-PTM become more efficient than UC. Results show that SC-PTM is the best solution for locally restricted and small-scale emergencies while MBSFN is more suitable for emergencies during massive events or wide-area scenarios.

“…Thus, the SE is further increased. The benefits of the SC-PTM mode over MBSFN in terms of SE is investigated in [5,6] for mission critical communications and in [7] for public safety communications. However, these work does not consider AL-FEC mechanism.…”

ÖZ3. nesil ortaklık projesi, ileri seviyede geliştirilmiş uzun vadeli evrim (LTE-A) ağları üzerinden geliştirilmiş çoklu multimedia servisleri için (eMBMS) uygulama katmanlı ileri hata düzeltme kodlarının (AL-FEC) kullanılmasını belirtmiştir. 3GPP, eMBMS'in veri iletimi için sabit bir modülasyon ve kodlama şeklinin (MCS) seçildiği tek frekanslı ağ (MBSFN) üzerinden kullanımını standardize etti. Spektral verimliliği artırmak için 3GPP tarafından tek hücreli noktadan çok noktaya (SC-PTM) iletim yöntemi tanımlandı. Bu nedenle, bu makalede LTE-A SC-PTM üzerinden AL-FEC'e dayanan çoklu video gönderimi önerilmektedir. Önerilen sistemin performansının analiz edilmesi için katmanlararası LTE-A simülatörü geliştirilmiştir. Simülasyon sonuçları önerilen sistemin LTE-A tarafından önerilen sisteme göre daha fazla kapsama alanı sağladığını (Sinyal Parazit Gürültü Oranında 4 dB gelişme sağlamaktadır) ve daha az radyo ve ağ kaynağı kullandığını (%48,7 daha fazla spektral verimlilik sağladığını) göstermektedir. MBSFN'den farklı olarak SC-PTM modu, kullanıcılardan geri bildirim alarak her bir gelişen düğümB'de (eNB) MCS gibi sistem parametrelerinin dinamik olarak seçilmesine izin verir.
