| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This paper introduces a transmission/reception technique based on mobile terminal collaboration that equivalently increases the number of antennas by sharing received signals among mobile terminals. To overcome the shortage of antennas on the mobile terminal side, multi-user MIMO (Multiple-Input Multiple-Output) transmission has been studied. However, the accuracy of precoding degrades in mobile environments. On the other hand, terminal collaboration systems, in which terminals collaborate to increase the equivalent number of antennas, eliminate the need for precoding and are therefore suitable for mobile environments. The terminal collaboration system requires high-speed and low-latency communications over short distances, making the use of high-frequency bands suitable. This terminal collaboration system has the potential to effectively expand the number of MIMO signal streams in the so-called platinum band by utilizing the high-frequency bands. In this presentation, we describe recent research results on the terminal collaboration system and its potential application to the uplink. |
