This disclosure relates to a method for reducing power consumption of a first device for use in a wireless communication system. The first device receives a signal within a first reference sub-frame of a radio channel. The device determines whether to use the signal for obtaining channel state information to be reported to a second device within a reporting sub-frame, or whether to receive and use a second signal within a second reference sub-frame of the radio channel for obtaining channel state information to be reported to the second device within said predetermined later sub-frame. Based on this determination, the first device reports channel state information obtained based on the signal received within said first reference sub-frame or said second signal within said second reference sub-frame to the second device within said reporting sub-frame.

A method for transmitting a plurality of uplink messages may include transmitting a first uplink message to a sink device and monitoring a feedback channel for feedback information from the sink device during one or more default feedback reception periods associated with the first uplink message. The method may further include skipping monitoring of the feedback channel during the remaining default feedback reception periods associated with the first uplink message if a number of consecutive default feedback reception periods containing positive feedback information exceeds a threshold, updating the threshold based on a channel quality measure, transmitting a second uplink message, and monitoring or skipping monitoring of the feedback channel during default feedback reception periods associated with a second uplink message based on the updated threshold.

Method for transmitting a plurality of uplink messages and mobile radio communication terminal device

A method for handover in a mobile communication system, wherein cell search is performed by determining cell identities based on cell identity information transmitted within downlink data is provided. The cell power of cells detected by cell search is measured. Moreover, the cell power of an additional cell is measured, the additional cell having a cell identity that is related to a cell identity of a cell detected by cell search in that the additional cell and the cell detected by cell search are adjacent cells. The method is applicable in cross-sector scenarios avoiding call drops due to lengthy cell detection.

Fast handover method for cross sector scenario in mobile communication systems

A method is provided for controlling measurements in a wireless telecommunications terminal. In a Long Term Evolution (LTE) wireless communication system, the network instructs a UE to measure the received power and quality of the reference signals of the serving cell as well as of neighbor cells. The object of improving the system power consumption of user equipment (UE) that has to perform such measurements is solved by distributing the measurement functionality between RRC and PHY layers such that the RRC layer is enabled to rest in a power save mode unless results of the measurements have to be reported to the network, and to be only active for a minimum to ensure that the UE still behaves standard compliant to the network.

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.
