Abstract

Listen-Before-Talk (LBT) is an essential function of many MAC protocols and a key mechanism of sharing spectrum in an uncoordinated manner. However, this simple but effective concept remains a major challenge for Software-Defined Radios (SDRs). If performing the protocol stack on a host PC, due to their structure, SDRs have inherent latencies built in. These latencies increase their reaction time, the so-called turnaround time, significantly, compared to their conventional radio counterparts. Unfortunately, this means that they can- not comply with the LBT channel access procedures used in modern protocols like IEEE 802.11 or LTE Licensed-Assisted Access (LTE-LAA). Given the flexibility and rapid-prototyping capabilities of SDRs, these protocols could clearly benefit from such SDR-based implementations. In this paper, we fill this gap and present a design approach for SDRs supporting LBT. We particularly focus on the rather complicated timing issues. As a proof-of-concept, we showcase our LBT-enabled implementation of the srsLTE software stack for LTE.
