The increased carrier bandwidth and the number of antenna elements expected in 5G networks require a redesign traditional IP-based backhaul CPRI-based fronthaul interfaces used 4G networks. We envision future mobile to encompass these legacy together with novel RAN functional splits. In this scenario, consistent transport network architecture able jointly support 4G/5G is paramount importance. article we present 5G-XHaul, featuring wireless optical technologies multi-technology software...
Abstract The common European Information and Communications Technology sector vision for 5G is that it should leverage on the strengths of both optical wireless technologies. In context, a wide spectra radio access technologies—such as millimetre wave transmission, massive multiple‐input multiple‐output new waveforms—demand high capacity, highly flexible convergent transport networks. As requirements imposed future networks rise, so do challenges in network. Hence, 5G‐XHaul proposes...
Fronthaul (FH) bandwidth in cloud radio access network (C-RAN) can be significantly reduced with an appropriate functional split by offloading more signal processing functionalities to the remote unit (RRU). However, this not only reduces acclaimed centralization benefits but also increases complexity of RRU. Considering practical aspects such as power consumption, cost, size and weight, it is often desirable make RRUs simple, yet efficient, possible. In paper, we analyze RRU 5G New Radio...
With the emergence of cloud radio access network (C-RAN) architecture, latency in fronthaul (FH) is a critical performance metric especially for ultra-reliable and low-latency communication applications. The stringent FH capacity requirements C-RAN can be relaxed by offloading some baseband functionalities to remote unit (RRU), referred as functional splitting. This allows packetized solutions such ubiquitous Ethernet. In this paper, we calculate uplink system with massive MIMO-based RRUs...
Cloud radio access network (C-RAN) is envisaged as a potential enabler of 5G and future generation mobile networks to meet the diverse stringent requirements use cases application scenarios due its promising advantages. For practical deployment, proposed C-RAN architecture should not only be cost effective but also energy efficient. Common public interface (CPRI) based fronthaul (FH) demands huge bandwidth new technologies (RATs), which necessitate large number high capacity transceiver...
Functional splitting and packetized fronthaul (FH) are two approaches to realize cloud radio access networks in a cost-effective manner. In the former, some baseband functionalities offloaded remote units (RRUs) instead of centralizing all them at unit pool. This reduces capacity latency requirements on FH when massive multiple-input-massive-output RRUs used. The latter approach aims use ubiquitous Ethernet for FH. However, this leads random packet delays due queuing switching/aggregating...
Despite the promising benefits of cloud-radio access network (C-RAN), fronthaul (FH) imposes stringent requirements in terms data rate, latency, jitter and synchronisation. In classical C-RAN, FH capacity scales linearly with number transmitting antennas, which has posed severe demands on capacity, especially due to emerging 5G technologies such as massive MIMO. However, this can be relaxed by performing precoding at remote radio units (RRUs) instead centrally, leading traffic depends...
Latency is the one of critical performance metrics for 5G and beyond mobile networks, particularly ultra-reliable low-latency communications (URLLC). In URLLC applications, it required that transmitted packets reach destination within a certain time are unable to meet this strict latency requirement will be discarded. paper, we compute waiting in packetized fronthaul at Ethernet switch packet loss rate (PLR) incurred due inability FH threshold. addition, derive tractable closed-form solution...
Cloud-radio access network (C-RAN) has been an attractive solution in the recent years for future generation mobile networks due to its promising benefits. However, transport link between remote radio unit (RRU) and baseband (BBU), known as fronthaul (FH), imposes stringent requirements terms of data rate, latency, jitter, synchronization. In conventional C-RAN, FH capacity scales linearly with number transmitting antennas, which posed severe demands on capacity, especially emerging 5G...
