Survey on Low Latency for 3gpp Lte

The rapidly increasing number of mobile devices, capacious data, and higher data rate are pushing to rethink the current generation of the cellular mobile communication. The next or fifth generation (5G) of the cellular networks is expected to meet the requirements. Pervasive connectivity, low latency and very high data transfer are the unique features of 5G networks. Long Term Evolution is a standard for high-speed wireless communication for mobile phones and data terminals, based on the GSM/EDGE and UMTS/HSPA technologies. It increases the capacity and speed using a different radio interface together with core network improvements. LTE is the upgrade path for carriers with both GSM/UMTS networks and CDMA2000 networks. The different LTE frequencies and bands used in different countries mean that only multi-band phones are able to use LTE in all countries where it is supported. LTE is commonly marketed as 4G LTE, but it does not meet the technical criteria of a 4G wireless service, as specified in the 3GPP Release 8 and 9 document series, for LTE Advanced.
