Uplink Transmissions in URLLC Systems with Shared Diversity Resources.
Abstract—
5G features flagship use cases with Ultra Reliable Low Latency Communication (URLLC), supported through high diversity. When multiple URLLC connections are only intermittently active, dedicating many diversity resources to a single connection leads to inefficient operation.
This paper addresses this problem through shared diversity resources and compare it to per-link dedicated diversity. Two receiver types are considered, MMSE (minimum mean squared error) and MMSE-SIC (successive interference cancellation). Outage probability is evaluated by assuming channel estimation errors. The results show that it is possible to remain close to the reliability of reference system with a relatively low amount of pre-allocated resources.
