A method of operating a terminal of a wireless communication network is disclosed, wherein the terminal operates according to a discontinuous reception mode. The wireless communication network comprises one or more wireless network nodes having at least first and second downlink transmission modes, the first downlink transmission mode comprising normal operation of a particular network node and the second downlink transmission mode comprising restricted downlink transmission of the particular network node and being applicable when the number of active terminals in the cell associated with the particular network node is less than or equal to a second mode threshold value. The method comprises detecting a cell identity for a cell associated with a wireless network node of the wireless communication system, determining a current downlink transmission mode of the wireless network node as the first or second downlink transmission mode, and adapting a time pattern based on the determined current downlink transmission mode, wherein the time pattern specifies when a receiver of the terminal is turned on. Corresponding computer program product and arrangement are also disclosed.

Abstract:
The present disclosure relates to a technique for avoiding, forestalling, or reducing re-establishment procedures in a telecommunications system having multiple carriers. A method aspect of this technique includes monitoring a signal quality of an anchor component carrier associated with a serving cell of a mobile terminal and used by the mobile terminal. If the signal quality of the anchor component carrier violates a first signal quality condition, then a parameter (of, e.g., a downlink signal) of at least one candidate component carrier associated with the serving cell and distinct from the anchor component carrier is measured and the signal quality of the at least one candidate component carrier is determined based on the measured parameter. If the determined signal quality fulfils a second signal quality condition, then reselection to the at least one candidate component carrier is initiated such that the candidate component carrier becomes the anchor component carrier associated with the serving cell and used by the mobile terminal.
Abstract:
In a cellular radio system Transmission Power Control (TPC) power offset is set so that it is adjusted for each transmitting radio base station based on available relevant measurements that reflect the quality of the downlink channel carrying the uplink TPC command whereby an improved performance is obtained. The TPC power offset can for example be based on an estimated uplink Dedicated Physical Control CHannel (DPCCH) SINR, the number of TPC “up” and the number of TPC “down” sent by a radio base station and aggregated UE receiver power or UE transmit power over a number N slots. Also a mobile station used in a cellular radio system supporting soft handover may be adapted to apply TPC discarding thresholds based on the number and the quality of simultaneously received TPC commands. The discarding procedure in the mobile station may also be carried out selectively such that TPC commands that are determined to be unreliable are not discarded but selectively discarded based on how reliable they are determined to be.
Abstract:
A wireless terminal (30) capable of operating in a discontinuous mode comprising and method for operating such wireless terminal (30) facilitate measurements pertaining to position of the wireless terminal (30). The method includes receiving a message from the radio access network (28). The measurement request message is configured to indicate that measurements are to be performed by the wireless terminal on downlink signals transmitted by the base station or by the base station on downlink signals transmitted by the base station. The method further comprises, as a result of or after receiving the message, changing operation of the wireless terminal (30) from a discontinuous mode to a modified mode to facilitate performance of the measurements. Relative to the discontinuous mode at least one of following are shortened or eliminated in the modified mode: (i) the non-reception periods, and (ii) the non-transmission periods. “Changing from a discontinuous mode . . . to a modified mode” includes one or more of: (1) changing mode of the wireless terminal (e.g., changing from a discontinuous mode [such as discontinuous reception (DRX) or discontinuous transmission (DTX)] to a continuous transmission mode); (2) changing from the discontinuous mode (a first discontinuous mode) to a modified discontinuous mode (a second discontinuous mode).
Abstract:
Wireless communication network terminal operation is disclosed. The network comprises wireless network nodes having first and second downlink transmission modes. The first mode involves normal operation of a particular network node and is applicable when a number of active terminals in a cell associated with the particular network node is greater than a first mode threshold value. The second mode involves restricted downlink transmission of the particular network node and is applicable when the number of active terminals in the cell associated with the particular network node is not greater than a second mode threshold value. A cell identity is detected for a cell associated with a wireless network node of the wireless communication system. A current downlink transmission mode of the node is detected as the first or second downlink transmission mode, and an operation of the terminal is adapted based on the detected current downlink transmission mode.
