Samsung and MediaTek say they completed an industry-first 3Tx five-layer 5G uplink validation using MediaTek's M90 modem platform and Samsung vRAN, Massive-MIMO and macro radio technology. The setup reached 670 Mbps across n66 and n77 spectrum. The signal for BTW readers is that uplink efficiency is becoming a sharper 5G-Advanced, FWA and RAN-asset optimisation battleground.

事实
三星和联发科表示，他们使用联发科M90 5G调制解调器平台以及三星的vRAN、大规模MIMO和宏基站无线电技术，完成了业界首个3Tx五层上行测试。该测试将1.7 GHz的n66作为主小区，结合3.7 GHz的双n77载波，使用30 MHz的n66和200 MHz的n77频谱，在上行吞吐量达到670 Mbps的同时，测试了多频段资源分配和频谱效率。 另见: 台积电权衡AI芯片涨价，面临短缺.
评估
这只是一次实验室验证，而非商业网络结果，但它表明5G性能压力正在向上行转移。随着FWA、云应用、视频创作和企业流量对用户到网络性能的要求提高，上行容量正变得更加具有战略意义。三星与联发科的测试与爱立信和KDDI最近进行的AI上行优化试验并列，标志着设备商正在更广泛地推动从现有频谱和RAN资产中提取更多可用容量。 另见: AI芯片通胀：设备制造商受挤压，影响超越数据中心.
关注点
关注运营商是否会在FWA和密集城市网络的现场试验中部署3Tx上行配置，这些场景中上行拥塞可能会抵消良好的下行覆盖。 另见: IBM 与 Google 扩展企业 AI 代理.
