US 2019/0174571 A1 · LIGHT CONNECTIVITY AND AUTONOMOUS MOBILITY

Abstract

Light and/or Inactive state connectivity and/or autonomous mobility techniques are contemplated. A WTRU may, for example, have an inactive/idle mode, a light connected/loosely connected/Inactive mode and/or a connected/fully connected/Active mode. A WTRU in light connected mode may have a WTRU context stored in a RAN. A WTRU may perform an area monitoring procedure while in light connected state. A WTRU may engage in autonomous mobility during light connectivity. A WTRU may move within a logical area (e.g., a RAN paging area), perhaps without notifying the network. The WTRU may provide notice when it has moved outside a logical area (e.g., update RAN paging area). Mobility in light connected state may be network controlled (e.g., to enable handover when data transfer may be allowed and/or ongoing). A WTRU may be reachable during a light connectivity state. A WTRU may engage in autonomous mobility during light connectivity and/or an Inactive state.

Dependent claims

A wireless transmit/receive unit (WTRU) comprising circuitry, including a receiver, a transmitter, a processor, and memory, wherein:

the receiver is configured to:
receive, from a network node of an access network, (i) a request to transition to a radio resource control (RRC) inactive state and (ii) context information indicating one or more logical channels (LCHs) that remain available for uplink (UL) transmission while in the RRC inactive state;
the processor is configured to:
transition to the RRC Inactive state with respect to the network node while remaining in an RRC connected state with respect to a core network;
and
the transmitter is configured to:
on condition that UL data associated with any of the indicated one or more LCHs becomes available for transmission and the UL data satisfies one or more criteria for transmission while in the RRC inactive state, transmit the UL data and an identity of the WTRU while in the RRC Inactive state.

4 more elements

A method used by a wireless transmit/receive unit (WTRU) for wireless communications, the method comprising:

receiving, from a network node of an access network, (i) a request to transition to a radio resource control (RRC) inactive state and (ii) context information indicating one or more logical channels (LCHs) that remain available for uplink (UL) transmission while in the RRC inactive state;
transitioning to the RRC inactive state with respect to the network node while remaining in an RRC connected state with respect to a core network;
and
on condition that UL data associated with any of the indicated one or more LCHs becomes available for transmission and the UL data satisfies one or more criteria for transmission while in the RRC inactive state, transmitting the UL data and an identity of the WTRU while in the RRC inactive state.
