Webb24 maj 2024 · Han et al. propose an authorization-free random access scheme. The scheme allows all active user equipment (UEs) to transmit their uplink information via time-frequency resources and utilizes the proposed integrated independent component analysis of channel-free estimation. Webb11 maj 2024 · Abstract: The grant-free random access (RA) can minimize the access delay but also brings severe data transmission interferences. To overcome this defect, we propose a new RA scheme that inserts a base station (BS) broadcasting message after user equipments (UEs) transmitting pilots.
