1. A method of wireless communication at a transmitting device, comprising:
- receiving one or more quality of service (QoS) flows from a protocol layer;
mapping the one or more QoS flows to one or more data radio bearers (DRBs) established between the transmitting device and a receiving device; and
transmitting a plurality of media access control (MAC) protocol data units (PDUs) corresponding to the one or more DRBs, each MAC protocol data unit (PDU) comprising;
a packet data compression protocol (PDCP) PDU comprising a PDCP header and a partially ciphered PDCP payload.

Abstract
Aspects of the present disclosure relate to methods and apparatuses for wireless communication using a protocol data unit (PDU) including a service data adaptation protocol (SDAP) PDU that has an unciphered header. The unciphered SDAP header facilitates various optimizations in wireless communication.

8. A method of wireless communication at a receiving device, comprising:
-
receiving a media access control (MAC) protocol data unit (PDU) comprising a packet data compression protocol (PDCP) PDU comprising a PDCP header and a partially ciphered PDCP payload; extracting a service data adaptation protocol (SDAP) PDU corresponding to one or more quality of service (QoS) flows, from the partially ciphered PDCP payload; and reading an SDAP header of the SDAP PDU to obtain information on the one or more QoS flows prior to deciphering an SDAP payload of the SDAP PDU. - View Dependent Claims (9, 10, 11)
