Abstract

Supporting time-sensitive communication in a radio spectrum shared with broadband data is challenging, especially if the unlicensed spectrum is being used. A Multi-Technology Access Point (MTAP) equipped with two different radio interfaces, which is serving both time-sensitive and broadband data, suffers from Head-of-Line (HOL) blocking phenomenon that severely degrades its latency performance. This paper presents an approach that utilizes the possibilities of Cross-Technology Communication (CTC) to solve this problem. With CTCforLowLat, the MTAP is equipped with only a single radio interface providing native support for the wireless technology used for broadband transmission while the radio technology to be used for time-sensitive communication is emulated through CTC. In the event of the arrival of a time critical data packet, we do not have to preempt any ongoing broadband data transmission of the MTAP but, instead, we embed the CTC emulated time-sensitive data frame into the not yet transmitted payload of an ongoing broadband transmission. Our approach offers a superior performance to state-of-the-art solutions requiring two radio interfaces and preemption because the overhead of channel access can be fully avoided in most of the cases. CTCforLowLat represents some kind of reverse virtualization, as it requires only a single radio interface at the MTAP, hence reducing the cost.
