B.4 Example implementation of Non-Terrestrial Networks

38.3003GPPNRNR and NG-RAN Overall descriptionRelease 17Stage 2TS

The following figure illustrates an example implementation of an Non-Terrestrial Network for transparent NTN payload:

Figure B.4-1: NTN based NG-RAN

The gNB depicted in Figure B-1 may be subdivided into non-NTN infrastructure gNB functions and the NTN Service Link provisioning System. The NTN infrastructure may be thought of being subdivided into the NTN Service Link provisioning System and the NTN Control function. The NTN Service Link provisioning System may consist of one or more NTN payloads and NTN Gateways.

The NTN payload is embarked on a spaceborne (or airborne) vehicle, providing a structure, power, commanding, telemetry, attitude control for the satellite (resp. HAPS) and possibly an appropriate thermal environment, radiation shielding.

The NTN Service Link provisioning System maps the NR-Uu radio protocol over radio resources of the NTN infrastructure (e.g. beams, channels, Tx power).

The NTN control function controls the spaceborne (or airborne) vehicles as well as the radio resources of the NTN infrastructure (NTN payload(s) & NTN Gateway(s)). It provides control data, e.g. Ephemeris, to the non-NTN infrastructure gNB functions of the gNB.

Provision of NTN control data to the gNB is out of 3GPP scope.

NOTE: The transport of NR-Uu protocol between the NTN Service Link provisioning system and the non-NTN infrastructure gNB functions is out of 3GPP scope.

At least the following NTN related parameters are expected to be provided by O&M to the gNB for its operation:

a) Earth fixed beams: for each beam provided by a given NTN-payload:

– The Cell identifier (NG and Uu) mapped to the beam;

– The Cell’s reference location (e.g. cell’s center and range).

b) Quasi Earth fixed beams: for each beam provided by a given NTN-payload:

– The Cell identifier (NG and Uu) and time window mapped to a beam;

– The Cell’s/beam’s reference location (e.g. cell’s center and range);

– The time window of the successive switch overs (feeder link, service link);

– The identifier and time window of all serving satellites and NTN-Gateways.

c) Earth moving beams: for each beam provided by a given NTN-payload:

– The Uu Cell identifier mapped to a beam and mapping information to fixed geographical areas reported on NG, including information about the beams direction and motion of the beam’s foot print on Earth;

– Its elevation wrt NTN-payload;

– Schedule of successive serving NTN-Gateways/gNBs;

– Schedule of successive switch overs (feeder link, service link).

Annex C (informative):
I-RNTI Reference Profiles

The I-RNTI provides the new NG-RAN node a reference to the UE context in the old NG-RAN node. How the new NG-RAN node is able to resolve the old NG-RAN ID from the I-RNTI is a matter of proper configuration in the old and new NG-RAN node.

Table C-1 below provides some typical partitioning of a 40bit I-RNTI, assuming the following content:

UE specific reference: reference to the UE context within a logical NG-RAN node;

NG-RAN node address index: information to identify the NG-RAN node that has allocated the UE specific part;

NOTE: RAT-specific information may be introduced in a later release, containing information to identify the RAT of the cell within which the UE was sent to RRC_INACTIVE. This version of the specification only supports intra-RAT mobility of UEs in RRC_INACTIVE.

PLMN-specific information: information supporting network sharing deployments, providing an index to the PLMN ID part of the Global NG-RAN node identifier.

Annex D (informative):
SPID ranges and mapping of SPID values to cell reselection and inter-RAT/inter frequency handover priorities

The SPID values are defined in Annex I of TS 36.300 [2].

From the SPID reference values, only the SPID=253 also applies for 5GC.

Annex E (informative):
NG-RAN Architecture for Radio Access Network Sharing with multiple cell ID broadcast

Each NG-RAN node serving a cell identified by a Cell Identity associated with either a subset of PLMNs, or a subset of SNPNs, or a subset of PNI-NPNs is connected to another NG-RAN node via a single Xn-C interface instance.

Each Xn-C interface instance is setup and removed individually.

Xn-C interface instances terminating at NG-RAN nodes which share the same physical radio resources may share the same signalling transport resources. If this option is applied:

– Non-UE associated signalling is associated to an Xn-C interface instance by including an Interface Instance Indication in the XnAP message;

– Node related, non-UE associated Xn-C interface signalling may provide information destined for multiple logical nodes in a single XnAP procedure instance once the Xn-C interface instance is setup;

NOTE 1: If the Interface Instance Indication corresponds to more than one interface instance, the respective XnAP message carries information destined for multiple logical nodes.

– A UE associated signalling connection is associated to an Xn-C interface instance by allocating values for the corresponding NG-RAN node UE XnAP IDs so that they can be mapped to that Xn-C interface instance.

NOTE 2: One possible implementation is to partition the value ranges of the NG-RAN node UE XnAP IDs and associate each value range with an Xn-C interface instance.

Annex F (normative):
Use and structure of the I-RNTI

The I-RNTI provides an NG-RAN node with a reference to the UE context and a reference to the NG-RAN node that allocated the UE context.

To support an NG-RAN node in resolving the Local NG-RAN ID of the NG-RAN node that allocated the UE context, the I-RNTI structure is as follows:

– the first part (starting from the MSB of the I-RNTI) identifies the I-RNTI profile. It is 2 bits long for a Full I-RNTI or 1 bit long for a short I-RNTI, and it indicates the length of a Local NG-RAN Node Identifier of the NG-RAN Node that allocated the I-RNTI;

– the second part, immediately following the first part, is a Local NG-RAN Node Identifier;

– the third part, immediately following the second part, identifies the UE context stored in the NG-RAN node that allocated the I-RNTI.

In case a NG-RAN node takes an additional Local NG-RAN Node identifier into use or removes a Local NG-RAN Node identifier currently in use it informs its neighbor NG-RAN nodes about this change.

The I-RNTI profiles for Full I-RNTI are described in table F-1.
