China Mobile, Huawei and Qualcomm Technologies said they completed the commercial verification of TDD+ uplink data compression technology on a commercial LTE-TDD network.
UDC is claimed to enable operators to maximize LTE-TDD uplink resources, increasing the number of uplink users and achieve compression efficiency for various applications such as messaging services and Web browsing.
Huawei said that the deployment of UDC does not require any hardware upgrade. On the network side, operators need only upgrade Huawei’s ENodeB software. On the terminal side, the technology is fully implemented in the LTE modem and thus completely independent from the mobile phone’s operating system.
Last month, the Chinese vendor launched its new TDD+ solution in collaboration with its industry partners China Mobile and Japanese telecom operator SoftBank. The solution is set to be commercially available next year.
Huawei said that the TDD+ technology can provide a multi-gigabit-per-second-level user experience, uncover more business opportunities for carriers and maximize their return on investment. TDD+ is also designed to increase spectral efficiency and system capacity by using high-performance cloud-baseband chips and features such as distributed multiple input/multiple output, massive carrier aggregation, high-order modulation, high-order MIMO and multiuser 3D beamforming.
In related news, China Mobile rolled out its voice-over LTE voice services in Zhejiang, the first province in China to enter into the VoLTE era. The rollout was carried out in partnership with Huawei, which recently won nearly half of China Mobile’s nationwide VoLTE project. The provinces involved in Huawei’s contract are Beijing, Shanghai, Tianjin, Guangdong, Zhejiang, Jiangsu, Fujian, Hunan, Guizhou, Shanxi, Guangxi, Jiangxi, Heilongjiang, Hubei, Anhui and Jilin.
China Mobile aims to provide services for 50 million commercial VoLTE subscribers by the end of 2015 or the beginning of 2016.
China Telecom ends first half of 2015 with 320,000 LTE base stations
China Telecom invested a total of 17.8 billion yuan ($2.8 billion) in its LTE network in the first half of 2015. The operator ended June with 320,000 LTE base stations across the country, and aims to reach 510,000 LTE base stations by the end of 2015.
By the end of the first half of the year, China Telecom had 29 million 4G terminal users, compared to 7 million at the end of last year.
The telco recorded revenue of 164.9 billion yuan in Q1 2015, down 0.6% vs. the year-ago period. The company’s net profits for the period totaled 10.9 billion yuan, down 4% year-on-year.
China Telecom is looking to provide LTE coverage to 95% of the country’s population by the end of the year, according to previous press reports.
The country’s No. 3 mobile company with approximately 192 million subscribers, China Telecom obtained its nationwide FDD-LTE license in February, having previously launched 4G services through a hybrid TDD/FDD network.
