Reconfigured uplink resource (PUR) for non-terrestrial networks (NTN)

A user equipment in a network comprising a plurality of mobile cells, comprising:

• a transceiver;
• one or more processors;
• and
• one or more non-transitory computer-readable storage media to store instructions executable by the one or more processors to cause the user equipment to:
• receive, via the transceiver, a radio resource control release message comprising configuration data, wherein the configuration data indicates one or more preconfigured uplink resources and indicates an association between each one of the mobile cells and a corresponding subset of the one or more preconfigured uplink resources, wherein the one or more preconfigured uplink resources enable the user equipment to perform a transmission without a connection to the network;
• select a first preconfigured uplink resource from a particular subset associated with one of the mobile cells, said selection being based on the user equipment being in a coverage area of one of the mobile cells;
• and
• transmit, via the transceiver, a first transmission using the first preconfigured uplink resource.

A base station of a serving cell in a network comprising a plurality of mobile cells, comprising:

• a transceiver;
• one or more processors;
• and
• one or more non-transitory computer-readable storage media to store instructions executable by the one or more processors to:
• transmit, via the transceiver, to a user equipment, a radio resource control release message comprising configuration data, wherein the configuration data indicates one or more preconfigured uplink resources and indicates an association between each one of the mobile cells and a corresponding subset of the one or more preconfigured uplink resources, wherein the one or more preconfigured uplink resources enable the user equipment to transmit to the network without a connection to the network;
• and
• receive a first transmission, via the transceiver from the user equipment based on the user equipment being in a coverage area of one of the mobile cells and using a first preconfigured uplink resource from a particular subset associated with the one of the mobile cells.
