Embodiment Construction

[0046]In some wireless communication systems, various applications (e.g., motion control, discrete manufacturing, etc.) can utilize low-latency communications (e.g., ultra-reliable low-latency communications (URLLC)) to Reliably send messages with minimal delay. In some cases, low-latency communications may occur concurrently with lower priority communications (eg, related to low-latency communications). In this way, the access node can employ Time Sensitive Networking (TSN), which includes a feature set that supports scheduling of hard real-time (hard RT) traffic (eg, low-latency communications) when communications of different priority levels occur simultaneously. Specifically, TSN may include a frame preemption feature that allows hard RT traffic to be prioritized over lower priority traffic in the time domain. In some cases, frame preemption can occur in a local area network (LAN) (eg, Ethernet) without affecting physical layer operations. Additionally, frame preemption ...

Abstract

Methods, systems, and devices for wireless communications are described. An access node may schedule traffic with different levels of priority for communications with a user equipment. The access nodemay receive a time-sensitive networking time-aware schedule from a first interface via an Ethernet frame that defines a set of periodic time intervals reserved for transmitting traffic with a high-priority (e.g., hard-real time traffic). In some cases, one or more frequency resources may additionally be reserved for the high-priority traffic. Accordingly, during the reserved time intervals, if the high-priority traffic is present, the access node may transmit the high-priority traffic on the reserved frequency resource(s). Outside the reserved time intervals, the access node may schedule lower-priority traffic on the reserved frequency resource(s) in addition to the other resources. Alternatively, high-priority traffic may interrupt previously scheduled lower-priority traffic during the reserved time intervals if high-priority traffic is present.

Description

[0001] cross reference [0002] This patent application claims the benefit of U.S. Patent Application No. 16 / 353,906, filed March 14, 2019, by HAMPEL et al., entitled "Time-SensitiveNetworking Frame Pre-Emption Across Cellular Interface," and HAMPEL et al., March 2018 Interest in U.S. Provisional Patent Application No. 62 / 644,976, filed on the 19th, entitled "Time-Sensitive Networking Frame Pre-Emption Across Cellular Interface"; assigned to its assignee. technical field [0003] The following relates generally to wireless communications, and more specifically to time-sensitive network (TSN) frame preemption across cellular interfaces. Background technique [0004] Wireless communication systems are widely deployed to provide various types of communication content such as voice, video, packet data, messaging, broadcast, and so on. These systems are capable of supporting communication with multiple users by sharing available system resources (eg, time, frequency, and power)....
