3.1 Terms p. 8
For the purposes of the present document, the terms given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
direct network connection:
one mode of network connection, where there is no relay UE between a UE and the 5G network.
emergency report:
in the context of this study, it is a data sent for emergency purpose (e.g., emergency messaging) and can be subject to international regulation.
indirect network connection:
one mode of network connection, where there is a relay UE between a UE and the 5G network.
satellite access:
direct connectivity between the UE and the satellite.
serving satellite:
a satellite providing the satellite access to a UE. In the case of NGSO (Non-Geostationary Satellite Orbit), the serving satellite is always changing due to the nature of the constellation.
S&F Satellite operation:
in the context of this study, S&F (Store and Forward) Satellite operation is an operation mode of a 5G system with satellite-access where the 5G system can provide some level of service (in storing and forwarding the data) when satellite connectivity is intermittently/temporarily unavailable, e.g. to provide communication service for UEs under satellite coverage without a simultaneous active feeder link connection to the ground segment.
S&F data retention period:
it is the data storage validity period for the 5G system with satellite access supporting store and forward operation (e.g. after which undelivered data stored is being discarded).
UE-Satellite-UE Communication:
for the 5G system with satellite access, it refers to the communication between UEs under the coverage of one or more serving satellites, using satellite access without going through the ground segment.
3.2 Abbreviations p. 9

4 Overview p. 10
The present document captures a set of use cases and potential service requirements related to the 5G system with satellite access taking into account new capabilities such as:
- S&F Satellite operation for delay-tolerant communication services: S&F Satellite operation is an operation mode of a 5G system with satellite-access, where the 5G system can provide some level of service (in storing and forwarding the data) when satellite connectivity is intermittently/temporarily unavailable, e.g. to provide communication service for UEs under satellite coverage without a simultaneous active feeder link connection to the ground segment. This is particularly relevant for delay-tolerant IoT services via NGSO space segment.
- UE-Satellite-UE communication: In some scenarios, UEs need to communicate using satellite access without going to the ground network in order to avoid long delays and limited data rate as well as reducing the consumption of backhaul resources.
- GNSS independent operation: This would allow to provide satellite access to UEs without GNSS receiver or with no access to GNSS services.
- Positioning enhancements for satellite access: 3GPP positioning methods are needed in some scenarios for UEs using only satellite access.
