At a glance

Technical Specification (TS) 38.141-2 V17.22.0 adds base station type 1-O to its co-location spurious emissions limits title.

What changed

Clause 6.7.5.5.5.1 covers test requirements for base station type 1-O. In V17.21.0, the co-location limits title read "OTA spurious emissions limits for BS co-located with another BS". In V17.22.0, that limits title reads "BS type 1-O OTA spurious emissions limits for BS co-located with another BS". BS means base station, and OTA means over-the-air. The clause title itself already named base station type 1-O in V17.21.0.

The sentence about the table notes was reworded in V17.22.0. Its new opening is "For a multi-band RIB". RIB means radiated interface boundary, where over-the-air requirements apply. For that condition, the table notes' exclusions and conditions apply for each supported operating band. The per-band ending also appeared in V17.21.0.

Change request 0735 made these clause edits and identifies inconsistencies between Technical Specifications 38.141-1 and 38.141-2. It lists work items for n65, n18 and frequency division duplex bands with variable duplex. The shown clause edits contain no numeric limit values or frequency-range values.

How this page was made

Written with AI assistance from two versions of the specification indexed by 3GPP Scout and the 3GPP CR database. An AI model (GPT-6 Sol) drafted each sentence and named the source it rests on. Code checked every quote word for word against the stored source text, and the live check fetched each TDoc again before publishing. A second AI model from another company (Claude Opus 5.5) reviewed the page against the same sources. The 3GPP documents themselves govern.
