  2. In Japan, SoftBank Mobile launched LTE-TDD services in February 2012 under the name Advanced eXtended Global Platform (AXGP), and marketed as SoftBank 4G (ja). The AXGP band was previously used for Willcom's PHS service, and after PHS was discontinued in 2010 the PHS band was re-purposed for AXGP service.[96][97]
  3. According to the European Telecommunications Standards Institute's (ETSI) intellectual property rights (IPR) database, about 50 companies have declared, as of March 2012, holding essential patents covering the LTE standard.[120] The ETSI has made no investigation on the correctness of the declarations however,[120] so that "any analysis of essential LTE patents should take into account more than ETSI declarations."[121] Independent studies have found that about 3.3 to 5 percent of all revenues from handset manufacturers are spent on standard-essential patents. This is less than the combined published rates, due to reduced-rate licensing agreements, such as cross-licensing.[122][123][124]

It increases the capacity and speed using a different radio interface together with core network improvements.[1][2] The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9. 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.

Further it is converted into bits per second depending on the how many bits a symbol can carry. Let’s consider LTE system with 20 MHz FDD mode , there are 100 Resource Blocks and each Resource block have 12x7x2=168 Symbols per ms in case of Normal CP. So there are 16800 Symbols per ms or 16800000 Symbols per second or 16.8 Msps. If modulation used is 64 QAM (6 bits per symbol) then throughput will be 16.8×6=100.8Mbps for a single antenna port.

RF and Wireless Terminologies

2004년, 3GPP는 IP를 미래의 차세대 네트워크로 제안하고 All IP 망(AIPN)의 타당성 조사를 시작했다. 제안서는 3GPP Release 7(2005)을 추천했으며,[11] 이는 LTE와 같은 상위 계층 OSI 모델 프로토콜의 기반이다. 인터넷 프로토콜(IP)는 OSI 모델 계층 3(네트워크 레이어) 프로토콜이다. 이러한 추천은 SAE(3GPP System Architecture Evolution)의 일부이다. 그러나 All IP 네트워크의 어떤 측면은 release 4에 이미 규정되어 있었다.[12] LTE Protocol Stack Layers - Let's have a close look at all the layers available in E-UTRAN Protocol Stack which we have seen in previous chapter. Below is a more ellaborated diagram of E-U LTE stands for Long Term Evolution[7] and is a registered trademark owned by ETSI (European Telecommunications Standards Institute) for the wireless data communications technology and a development of the GSM/UMTS standards. However, other nations and companies do play an active role in the LTE project. The goal of LTE was to increase the capacity and speed of wireless data networks using new DSP (digital signal processing) techniques and modulations that were developed around the turn of the millennium. A further goal was the redesign and simplification of the network architecture to an IP-based system with significantly reduced transfer latency compared with the 3G architecture. The LTE wireless interface is incompatible with 2G and 3G networks, so that it must be operated on a separate radio spectrum. LTE Throughput Optimization is one of the most frequently discussed topic. So, I have decided to write about the various aspects which can help in LTE throughput optimization

LTE Network Infrastructure and Elements - lteencyclopedi

LTE has been marketed both as "4G LTE" and as "Advanced 4G",[citation needed] 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. LTE is also commonly known as 3.95G. The requirements were originally set forth by the ITU-R organisation in the IMT Advanced specification. However, due to marketing pressures and the significant advancements that WiMAX, Evolved High Speed Packet Access, and LTE bring to the original 3G technologies, ITU later decided that LTE together with the aforementioned technologies can be called 4G technologies.[3] The LTE Advanced standard formally satisfies the ITU-R requirements to be considered IMT-Advanced.[4] To differentiate LTE Advanced and WiMAX-Advanced from current 4G technologies, ITU has defined them as "True 4G".[5][6] This page describes LTE PUSCH channel or Physical Uplink Shared Channel with respect to LTE system.

The LTE specification provides downlink peak rates of 300 Mbit/s, uplink peak rates of 75 Mbit/s and QoS provisions permitting a transfer latency of less than 5 ms in the radio access network. LTE has the ability to manage fast-moving mobiles and supports multi-cast and broadcast streams. LTE supports scalable carrier bandwidths, from 1.4 MHz to 20 MHz and supports both frequency division duplexing (FDD) and time-division duplexing (TDD). The IP-based network architecture, called the Evolved Packet Core (EPC) designed to replace the GPRS Core Network, supports seamless handovers for both voice and data to cell towers with older network technology such as GSM, UMTS and CDMA2000.[21] The simpler architecture results in lower operating costs (for example, each E-UTRA cell will support up to four times the data and voice capacity supported by HSPA[22]). In uplink we have only one transmit chain at UE end so no MIMO benefits. So with 20 MHz we can get Maximum of 100.8 Mbps as calculation shown above with single antenna. After considering 25% of overhead of SRS, PUCCH, PRACH etc. we get 75Mbps in uplink. For uplink there are certain constraints about modulation, this 75 Mbps throughput number is to be considered with 64 Modulation support at uplink. Most of eNodeB does support 64 QAM in uplink but few UE only support 16 QAM as maximum modulation in uplink.Long-Term Evolution Time-Division Duplex (LTE-TDD), also referred to as TDD LTE, is a 4G telecommunications technology and standard co-developed by an international coalition of companies, including China Mobile, Datang Telecom, Huawei, ZTE, Nokia Solutions and Networks, Qualcomm, Samsung, and ST-Ericsson. It is one of the two mobile data transmission technologies of the Long-Term Evolution (LTE) technology standard, the other being Long-Term Evolution Frequency-Division Duplex (LTE-FDD). While some companies refer to LTE-TDD as "TD-LTE" for familiarity with TD-SCDMA, there is no reference to that acronym anywhere in the 3GPP specifications.[72][73][74] In the U.S., Clearwire planned to implement LTE-TDD, with chip-maker Qualcomm agreeing to support Clearwire's frequencies on its multi-mode LTE chipsets.[98] With Sprint's acquisition of Clearwire in 2013,[75][99] the carrier began using these frequencies for LTE service on networks built by Samsung, Alcatel-Lucent, and Nokia.[100][101]
