Overview
Antenna Ports belongs to the broader PHY topic set covered by the Release 18 specification baseline. It matters because port-based reference-signal and channel interpretation across nr phy. This page will expand into a full reference entry so the main website carries the usable explanation directly.
Scope
The completed page will cover definition, where the topic fits in PHY, main behavior, related procedures, practical reading notes, troubleshooting value, and links to the nearest channels, signals, and control areas.
- Read it together with the main PHY overview.
- DMRS - DMRS interpretation often depends on antenna-port understanding.
- CSI-RS - CSI-RS resources and ports are closely connected.
- Precoding and Codebooks - Spatial transmission and ports should be read together.

FAQ
Why does this page exist already if the full topic is still growing?
The PHY library works better when the main structure is visible early. This page keeps the topic connected to the rest of the PHY section while the full reference coverage is added.
