HSPA+ key technologies for better user experience
Enhanced CELL_FACH
Reduce the latency of user and control plane in the CELL_FACH, CELL_PCH
and URA_PCH state by higher data peak rate
Reduce state transition delay from CELL_FACH, CELL_PCH and URA_PCH
state to CELL_DCH state
Reduce call setup delay and HTTP response time
CPC (Continuous Packet Connectivity)
DTX_DRX save power consumption of terminal so that more users can stay inCELL_DCH state and spend less time in reactivation with no need of state transfer.
L2 Enhancement
With flexible RLC PDU size, small size will be configured in poor
coverage area in order to be sent successfully.
