Cover Story: Grant-free access is promising for supporting massive random access with low latency. In grant-free access, the length of pilots used for joint activity detection and channel estimation (JADCE) is limited by the duration of access slot and becomes the bottleneck for system performance, especially for base-station with multiple antennas. The inter-user interference (IUI) caused by non-orthogonal pilots is random owing to random access and it affects the JADCE performance. This paper focuses on pilot design to reduce pilot overhead for grant-free access. Compared with the existing designs, which reduce the mean IUI to users, the proposed pilot design exploits the IUI distribution to shorten its tail and consequently improves JADCE performance. View this paper
