The performance of contention-based access mechanism mainly depends on the resource allocation. This paper presents a generalized resource allocation scheme to support access prioritization in a multichannel slotted ALOHA system. The proposed scheme has great usability as it can be implemented in any similar mechanism such as OFDMA, which is used in LTE and beyond. We simulate its access-success probability and access delay in a one-shot random access attempt. The result demonstrates that the scheme can be used to represent any resource allocation schemes, such as dedicated, shared, partially-shared, as well as arbitrary resource allocation.
