In the New Radio Access Network architecture (New RAN), currently envisioned by 3GPP, the evolved NodeB (eNB) functions can be split between a Distributed Unit (DU) and Central Unit (CU). Furthermore, as per the Virtual RAN (VRAN) approach, such functions can be virtualised (e.g., in simple terms, deployed in virtual machines). In such scenario, the fronthaul network connecting DU and CU must fulfill...
The high risk of random access collisions leads to huge challenge for the deployment massive Machine-Type Communications (mMTC), which cannot be sufficiently overcome by current solutions in LTE/LTE-A networks such as the extended access barring (EAB) scheme. The recently studied approaches of grouped random access have shown a great potential in simultaneously reducing the collision rate and the...
Machine-to-Machine (M2M) communication is considered one of the essential elements of the Internet of Things (IoT) for enabling objects to communicate over potentially large distances. It is predicted to be the dominant source of traffic in 5G networks. To enable M2M communications on LTE networks, which is considered the main cellular access technology for M2M communications, several issues need...
Active queue management (AQM) is broadly accepted as the tool of choice for tackling bufferbloat (the accumulation of large queueing delays) in network buffers. CoDel and PIE are considered two of the most promising AQM schemes, but little has been done to adopt them in cellular networks, which are particularly plagued by bufferbloat. This is partly due to the lack of adequate evaluation of their...
In the world of Internet of Things (IoT), it is desired that every IoT device is able to communicate with the network all the time. Among various technologies to enable network connectivity, Long Term Evolution (LTE) is by far the most ubiquitous technology to provide coverage for IoT devices. The IoT devices are inherently resource constraint and efficient communication is one of the primary requirements...
Almost Blank Subframes (ABSs) are an important part of enhanced Inter-Cell Interference Coordination in 3GPP standard. The concept of ABS is to blank some subframes of macro base stations (MBSs), therefore, PBSs can have no interference from MBSs during these periods. In this work, we propose Multi-tone ABS to enhance ABS, which is referred to single-tone since only two choices can be applied on each...
Data applications can tolerate an initial delay before packet transmission begins. It is possible to take advantage of this initial delay to reduce the energy required to operate the small access points (SAPs) and decrease transmission power in small cell networks. To demonstrate the trade-off between delay and transmit power, we consider a simple access scheme and analyze the distribution of the...
