CoMP (2): CoMP Coordination Areas Defined in 3GPP (7 Scenarios)

In the CoMP scenarios defined in 3GPP Release 111 and Release 122, CoMP is used within a single eNB (intra-eNB) with ideal backhaul only - in restricted areas in Release 11 among eNBs (inter-eNB) with non-ideal backhaul as well - in more expanded areas in Release 12 According to NGMN3, ideal backhaul refers to one with latency of 2.5 usecs or less and capacity of 10 Gbps or higher, whe...

CoMP (1): CoMP Types - CS, CB, JT and DPS

Today, we will learn about CoMP, an inter-cell cooperation technology in LTE-A, since we learned about ICIC and eICIC in the previous posts. At an early stage of LTE/LTE-A, offering high speed is the most important marketing point for operators. However, as LTE subscribers and traffic grow, satisfying users with high Quality of Experience (QoE), for example, by improving user throughputs at cel...

Interference Coordination in LTE/LTE-A (2): eICIC (enhanced ICIC)

Enhanced Inter-Cell Interference Coordination (eICIC) As noted in the previous post about ICIC, we will find out about enhanced Inter-Cell Interference Coordination (eICIC), an interference control technology in LTE-A in this post. In LTE/LTE-A, one key challenge for operators is that they have to increase network capacity to keep up with fast-growing traffic. Especially, crowded areas in m...

Interference Coordination in LTE/LTE-A (1): Inter-Cell Interference Coordination (ICIC)

As mobile communication technology has evolved dramatically, from LTE (10 MHz) to LTE-A (10+10 MHz), and then to wideband LTE (20 MHz), South Korea's mobile market is hotter than ever with its big 3 operators competing fiercely in speed and quality (see Netmanias Report, LTE in Korea UPDATE - May 1, 2014). Operators can offer different maximum speeds depending on how wide frequency bandwidt...
