Abstract: Systems and methods are for configuring a periodic uplink (UL) resource on a first carrier of a user equipment (UE); transmitting a buffer status report (BSR) on the first carrier using the configured UL resource, the buffer status report indicating a request for transmission resources on a second carrier; receiving an UL grant for data transmission on the second carrier, the UL grant indicating transmission resources on the second carrier; and transmitting a user data packet on the second carrier using the transmission resources indicated in the UL grant.

Abstract: A user equipment (UE) may establish a connection with a network for transmission of a plurality of data bursts further comprising a plurality of data segments. The UE may transmit, to the network, a first data segment corresponding to a first quality of service flow identifier (QFI) associated with a first quality of service (QoS) flow and a second data segment corresponding to a second QFI associated with a second QoS flow. The UE may be configured to map one or more data segments to one or more QFIs based on at least one of a slice type, a frame type, a modulo operation, and a sequence number. The plurality of data bursts may be transmitted according to at least one of one or more configured grants (CGs), one or more dynamic grants (DGs), and one or more instances of the one or more CGs or one or more DGs.

Abstract: Embodiments disclosed herein include methods and apparatuses that enable the UE to transmit message 3 in an NTN network. A gNB can include, a time duration indicating the time at which the UE should transmit message 3. The network can ensure that the UE has adequate time to apply the timing advance, assemble and transmit message 3. The UE can compute time of UL grant application based on a timing advance. The time of application of the UL grant can be determined by the UE and by the gNB according to a specified rule.
