Method for controlling operation activity modes of a wireless telecommunications terminal
First Claim
1. A method for controlling operation activity modes of a telecommunications terminal affiliated to a wireless telecommunications network, comprising receiving configuration data from the network upon connection to the network at a Radio Resource Control (RRC) layer of a protocol stack of the terminal;
- the method further comprising;
communicating said configuration data from the RRC layer to a physical layer entity of the terminal; and
the physical layer entity controlling a stack controller entity of the terminal to go into and off a power save mode as a function of said configuration data and as a function of any activity events detected,wherein said stack controller entity executes functionality of layers above the physical layer entity,wherein said configuration data comprise Semi-Persistent Scheduling (SPS) configuration data, andwherein the controlling the stack controller comprises, in case of unsuccessful data transmission received at the physical layer entity, the physical layer entity proceeding with downlink retransmission according to a Hybrid Adaptive Response and Request (HARQ) rotocol and keeping the stack controller in a power save mode until data transmission is successful.

Abstract
A method is provided for controlling Discontinuous Reception (DRX) mode in telecommunication user equipment (UE), with the object to improve system power consumption of a UE of a wireless communication system that is running the DRX mode in RRC_CONNECTED state. In an LTE communication system, DRX functionality is applied to the Medium Access Control (MAC) layer to discontinue monitoring the Physical Downlink Control Channel (PDCCH) for certain periods in order to reduce power consumption of the UE. Typical physical UE implementations have the stack controller and the Physical Layer (PHY) running on several hardware blocks that can enter power saving modes independently. The method comprises a partitioning of the functionality between stack controller and PHY layer that allows the stack controller entity to be active at a minimum while ensuring that the UE still behaves standard compliant to the network.
