At a glance

At RAN2 #135, RAN2 agreed to confirm gNB generation of the transaction identifier for Release 20 Ambient Internet of Things (IoT) Topology 2.

What was agreed

RAN2 is the radio access network working group for radio layer 2 and radio resource control. A gNB is a network base station, and ID means identifier in the recorded outcome. For agenda item 8.2.3, the meeting report records "Confirm the working assumption that the transaction ID is generated by the gNB". Our reading: Confirming this working assumption makes gNB generation an agreement, not a provisional assumption.

Sharp proposed "Confirm the following working assumption: the transaction ID is generated by the gNB". China Mobile wrote that the working assumption could be confirmed. Huawei, with HiSilicon, also proposed confirming that the gNB generates the transaction ID. These are company positions, while the meeting report records the agreement.

The report separately lists reader assistance for resource allocation under Release 20 Ambient IoT phase two. That contribution was noted, not recorded as part of the transaction-ID agreement.

How this page was made

Written with AI assistance from TDocs indexed by 3GPP Scout. 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.
