Qualcomm expanded its Chinese telecom footprint in a 6G demo with China Mobile.<\/p>\n
Claimed to be a world-first operator\u2013chipmaker validation, Qualcomm China worked with the operator on a 6G prototype base station and terminal using the upper 6 GHz (U6G) band (6425\u20137125 MHz) with 3GPP-defined wide-bandwidth baseband and radio frequency RF alignment requirements.<\/p>\n
Carried out at China Mobile\u2019s Collaborative Innovation Base, the test utilized Qualcomm\u2019s 4T8R U6G terminal prototype, which touts 4 transmit and 8 receive chains. Integrated together were the U6G band, a 400 MHz downlink and 200 MHz uplink ultra-large channel bandwidth, plus a 128-channel ultra-large massive multiple-input, multiple-output (MIMO) base station.<\/p>\n
According to both companies, the demonstration confirmed the feasible co-evolution of future 6G networks, terminals, and services. The development follows China\u2019s 6G push with the launch this year of its second phase of technical trials<\/a>. The drive helps form part of China\u2019s 15th Five-Year Plan running from this year to 2030, which aims to steer the country in areas such as artificial general intelligence (AGI), sovereign semiconductor stacks, and quantum networking.<\/p>\n China\u2019s advancements in 6G have since seemingly trumped American efforts, first with the launch of a pre-6G test network<\/a> in the city of Nanjing, which touted support from Qualcomm, and later with the approval of the 6 GHz band<\/a> for large-scale 6G field trials and technical standardization.<\/p>\n
