Embodiment Construction

[0067] Different transmissions utilizing time-division duplex (TDD) or frequency-division duplex (FDD) and involving low-latency communication (LLC) user equipment (UE), base stations, and side-link UEs in a geographic area may cause interference that prevents Or reduce the efficiency of low-latency based communication between base station and LLC UE. For example, in an FDD system, LLC UEs (e.g., UEs capable of LLC communications such as Ultra-Reliable Low-Latency Communications (URLLC)) can send LLC transmissions in a grant-free manner to the uplink allocated for sidelink data. Route resources are punched. Sidelink UEs may also transmit sidelink data via the same resources allocated to sidelink data during the same or overlapping times—causing interference to the transmitted signal. The LLC data may not have been successfully received or decoded, and the LLC UE may need to resend the LLC data using resources otherwise allocated to sidelink data. As another example, the base...

Abstract

Systems, methods, and devices for wireless communications are described. In an FDD system, a UE may recognize an indicator associated with ultra-reliable low-latency communication (URLLC) while communicating in a sidelink channel. The UE may also identify dedicated uplink resources in the sidelink channel and reserve the dedicated uplink resources. Dedicated uplink resources may be reserved for acknowledgment / negative acknowledgment (ACK / NACK) feedback or for scheduling requests (SRs). URLLC data can be transmitted and ACK / NACK feedback or SR can be sent using the reserved uplink resources. In a TDD system, a base station may transmit information identifying dedicated resources for URLLC data. In some cases, the base station may transmit an indicator channel that the sidelink UE may monitor for the presence of URLLC data and respond accordingly.
