This paper proposes an unsourced random access (URA) scheme that can accommodate massive connectivity in the fifth generation (5G) and future 6G mobile networks. While most of conventional studies on URA have assumed narrowband transmission over flat fading channels, the proposed scheme supposes that broadband signals are transmitted from some user terminals to one base station (BS) equipped with massive multiple-input multiple-output (MIMO) receive antennas. Since such transmitted signals can experience frequency selective fading, the paper employs orthogonal frequency division multiplexing (OFDM), where the transmitted signals are spread over time-frequency domain. The transmission frame is partitioned into several slots and each user independently selects one slot for uplink packet transmission upon the index modulation (IM) principle. Each packet is composed of the following three parts: The first part activates a slot index while the second part selects one pilot sequence and random access pattern (RAP) from a common pool. The remaining part is polar encoded and the corresponding modulated symbols are spread over the whole selected slot. On the receiver side of the proposed scheme, concatenated activity detection (AD) is proposed to detect the active pilot indices with low complexity. Using both the result of AD and estimated channel frequency responses, the multiuser detector of the proposed scheme provides soft information on the coded bit sequences for single-user channel decoders that can extract data bit sequences. Furthermore, successive interference cancellation (SIC) is meticulously designed and repeats subtraction of detected signals from the received signals, which can gradually improve the message recovery performance. computer simulations demonstrate that the proposed scheme can achieve excellent packet recovery and convergence performance over frequency selective channels while avoiding a considerable increase in computational complexity.
