full_form: Integrated Access and Backhaul
context: The IAB-node can reduce UL scheduling latency through signalling of a Pre-emptive BSR to its parent node. The IAB-node can send the Pre-emptive BSR based on UL grants it has provided to child nodes and/or UEs, or based on BSRs it has received from child nodes or UEs (Figure 4.7.3.3-1). The Pre-emptive BSR conveys the data expected rather than the data buffered. Figure 4.7.3.3-1: Scheduling of BSR in IAB: a) regular BSR based on buffered data, b) Pre-emptive BSR based on UL grant, c) Pre-emptive BSR based on reception of regular BSR
description: Integrated Access and Backhaul (IAB) is a technology that enables the integration of access and backhaul links in wireless networks. It allows for more efficient use of spectrum and resources, reducing latency and improving overall network performance. In the context of 3GPP specifications, IAB-nodes can utilize Pre-emptive Buffer Status Reports (BSR) to signal expected data transmission, thereby optimizing uplink scheduling and reducing latency.
explanation: IAB is classified as a Technology because it represents an innovative approach to managing access and backhaul in wireless networks. The provided context highlights its application in reducing UL scheduling latency through the use of Pre-emptive BSR, demonstrating its alignment with 3GPP's goals for efficient network operations.
