Introduction • “Service Specific BR without STID Header” is sent through dedicated UL resource

Introduction • “Service Specific BR without STID Header” is sent through dedicated UL resource assigned to the AMS, which needs to change the scheduling parameters of its service flow – That is, Qo. S parameter switching is done via this specific BR header • When the Qo. S parameter set is alternated, so as the traffic characteristics • The goal of sleep mode is to mimic the traffic characteristic of a service flow – In 802. 16 m, multiple sets sleep mode configuration are configured with SCIDs • Motivation: is it possible to combine the Qo. S parameter set updating and SCID updating in a single procedure? – The sleep mode configuration could be updated accordingly • Benefit: – No MOB_SLP-REQ/RSP are required 2

Observation • There are 14 reserved bits in service specific BR without STID header
