Section: 6.4.2 Requirements 6.4.2.1 General
Content: The 5G system shall minimize control and user plane resource usage for data transfer from send only UEs. The 5G system shall minimize control and user plane resource usage for stationary UEs (e.g. lower signalling to user data resource usage ratio). The 5G system shall minimize control and user plane resource usage for transfer of infrequent small data units. The 5G system shall optimize the resource use of the control plane and/or user plane for transfer of small data units. The 5G system shall optimize the resource use of the control plane and/or user plane for transfer of continuous uplink data that requires both high data rate (e.g. 10 Mbit/s) and very low end-to-end latency (e.g. 1-10 ms). The 5G network shall optimize the resource use of the control plane and/or user plane to support high density connections (e.g. 1 million connections per square kilometre) taking into account, for example, the following criteria: - type of mobility support; - communication pattern (e.g. send-only, frequent or infrequent); - characteristics of payload (e.g. small or large size data payload); - characteristics of application (e.g. provisioning operation, normal data transfer); - UE location; - timing pattern of data transfer (e.g. real time or non-delay sensitive). The 5G system shall efficiently support service discovery mechanisms where UEs can discover, subject to access rights: - status of other UEs (e.g. sound on/off); - capabilities of other UEs (e.g. the UE is a relay UE) and/or; - services provided by other UEs (e.g. the UE is a colour printer). The 5G system shall be able to minimise the amount of wireless backhaul traffic (e.g. consolidating data transmissions to 1 larger rather than many smaller), when applicable (e.g. providing service in an area subject to power outages). The 5G system shall support small form factor UEs with single antenna. NOTE: Small form factor UEs are typically expected to have the diagonal less than 1/5 of the lowest supported frequency wave length. Satellite access related resource efficiency requirements are covered in clause 6.46.5.
