In recent years, the increasing demand for mobile data services has promoted the acceleration of LTE network commercialization. Throughout the world, LTE commercial networks are still dominated by lte fdd, but with the gradual development of their networks, users and businesses are increasing, lte fdd network frequency
China's LTE commercialization is approaching, and the industry's attention to the subsequent evolution of LTE has reached a new peak. Compared with 3G, LTE significantly improves the spectrum efficiency. However, the industry has not stopped. A few years ago, 3GPP began to research and develop the LTE-Advanced standard

At present, there are two 4G standards based on LTE, namely lte fdd and lte tdd (China is used to call lte tdd TD-LTE, both stand
Currently there are two 4G standards based on LTE, namely LTE FDD and LTE TDD (the domestic custom of LTE TDD is called Td-lte). See the name you will have an intuitive impression, the two standards are based on the different branches of

-frame is to allow the terminal to decode the downlink dispatch information at an early stage (the translator note: The terminal can know how to decode the Dl-sch information), so that the terminal before the end of the sub-frame transmission can be Dl-sch demodulation and decoding, reduce dl-sch decoding delay, This reduces the delay of the overall downstream transmission. More importantly, the control domain is placed at the beginning of the sub-frame, then those non-scheduled terminals do not

Influence of LTE technology on PTN
China and the rest of the world are entering the brand new 4G/LTE era at full speed. As a mobile return technology, PTN faces severe challenges even after years of evolution and maturity. Some of these technological changes are huge enough to trigger a PTN revolution. This article takes into account the deployment of macro base stations and micro base stations, and review
Network Collaboration of TD-LTE
Is there mutual interference between the TD-LTE and the current 2G system in the adjacent frequency? How can this problem be solved?
A: In actual network deployment, the F-band (1880-1915 MHz) TD-LTE base station will be affected by the stray/blocking/Intermodulation Interference of DCS1800, the Second Harmonic Interference of GSM
Latest Advances in TD-LTE Testing
At present, the first phase of core network, transmission, bearing and security testing work has been completed in the six test fields of TD-LTE. The results meet the test expectations, and all of them have entered the formal test conditions, in the future, the wireless performance, multi-antenna, terminal, indoor distribution system, network management and other aspects of
In December 5, Wei leping, director of China Telecom Technology Commission, said that after China Telecom obtained a 4G license, it will coordinate the coordinated development of LTE and FTTH and give full play to its respective advantages ~ In the past 10 years, LTE and FTTH will be two major technical levers for China Telecom. In terms of 4G network planning, China Telecom will first adopt TDD and FDD hyb

Layered Structure of LTE air Interfaces
LTE air interface layer structure, and WCDMA air interface layer structure is the same, from top to bottom is also divided into several layers of RRC-PDCP-RLC-MAC-PHY, RRC belongs to the network layer, PDCP, RLC and MAC belongs to the link layer, PHY belongs to the physical layer. T
With the division of spectrum resources, a huge rock in the road of TD-LTE commercialization was moved. At the recently held "TD-LTE technology and spectrum Seminar", China's 2.6GHz spectrum planning scheme was announced,-2690hz of the 2.6GHz band all divided into TDD spectrum. The determination of spectrum division, which sent a clear signal to the TD-LTE indust
