Licensed band fallback for wireless devices that operate in unlicensed bands
Aspects of the present disclosure describe a fallback silencing mechanism for wireless communications. A wireless device that operates primarily on unlicensed frequency bands, such as a factory automation device, may occasionally have a need to make Ultra-Reliable Low-Latency Communication (URLLC) transmissions. If the unlicensed band becomes unsuitable for URLLC transmissions, the wireless device may fallback to licensed band transmissions. A silencing signal may be sent on downlink resources to silence uplink Enhanced Mobile Broadband (eMBB) transmissions for one or more mini-slots. The wireless device may then send a URLLC transmission on the one or more min-slots.
