1. A method of wireless communications, comprising:
receiving, by a user plane of a base station from a control plane of the base station, a quality of service (QoS) update,
wherein the QoS update comprises information indicative of (1) a mapping between a QoS flow and a corresponding radio resource for user data transmission, and (2) one or more quality of service flow identities (QFIs) for one or more quality of service (QoS) flows that are non-access stratum (NAS) reflective, and
wherein the QoS update is received in response to the QoS flow and the corresponding radio resource that are remapped by the control plane of the base station;
storing, at the user plane, the information from the QoS update;
receiving, by the user plane, a downlink data packet of the QoS flow from a core network, wherein the downlink data packet comprises a quality of service flow identity (QFI);
performing a determination that the QFI is same as one of the one or more QFIs that are NAS reflective; and
transmitting, by the user plane, the downlink data packet of the QoS flow on the corresponding radio resource, wherein the downlink data packet is transmitted with the QFI in the downlink data packet in response to the determination.
